The European Society of Gastrointestinal Endoscopy (ESGE) presents a short list of performance measures for colonoscopy in inflammatory bowel disease (IBD) patients. Current performance measures for colonoscopy mainly focus on detecting (pre)malignant lesions. However, these performance measures are not relevant for all colonoscopy indications in IBD patients. Therefore, our aim was to provide endoscopy services across Europe and other interested countries with a tool for quality monitoring and improvement in IBD colonoscopy. Eight key performance measures and one minor performance measure were recommended for measurement and evaluation in daily endoscopy practice.

Background and aims: Achieving adequate bowel cleansing is of utmost importance for the efficiency of colon capsule endoscopy (CCE). However, information about predictive factors is lacking. The aim of this study was to assess the predictive factors of poor bowel cleansing in the CCE setting. Methods: In this observational study, 126 patients who underwent CCE at two tertiary care hospitals were included between June 2017 and January 2020. Participants prepared for bowel cleansing with a 1-day clear liquid diet, a 4-L split-dose polyethylene glycol regimen and boosters with sodium phosphate, sodium amidotrizoate and meglumine amidotrizoate. Domperidone tablets and bisacodyl suppositories were administered when needed. Overall and per-segment bowel cleansing was evaluated using a CCE cleansing score. Simple and multiple logistic regression analysis were carried out to assess poor bowel cleansing and excretion rate predictors. Results: Overall bowel cleansing was optimal in 53 patients (50.5%). Optimal per-segment bowel cleansing was achieved as follows: cecum (86 patients; 74.8%), transverse colon (91 patients; 81.3%), distal colon (81 patients; 75%) and rectum (64 patients; 66.7%). In the univariate analysis, elderly (OR, 1.03; 95% CI (1.01¿1.076)) and constipation (OR, 3.82; 95% CI (1.50¿9.71)) were associated with poor bowel cleansing. In the logistic regression analysis, constipation (OR, 3.77; 95% CI (1.43¿10.0)) was associated with poor bowel cleansing. No variables were significantly associated with the CCE device excretion rate. Conclusion: Our results suggest that constipation is the most powerful predictor of poor bowel cleansing in the CCE setting. Tailored cleansing protocols should be recommended for these patients.

Background: The "diagnose-and-leave-in" policy has been established to reduce the risks and costs related to unnecessary polypectomies in the average-risk population. In individuals with Lynch syndrome, owing to accelerated carcinogenesis, the general recommendation is to remove all polyps, irrespective of size, location, and appearance. We evaluated the feasibility and safety of the diagnose-and-leave-in strategy in individuals with Lynch syndrome. METHODS : We performed a post hoc analysis based on per-polyp data from a randomized, clinical trial conducted by 24 dedicated colonoscopists at 14 academic centers, in which 256 patients with confirmed Lynch syndrome underwent surveillance colonoscopy from July 2016 to January 2018. In vivo optical diagnosis with confidence level for all detected lesions was obtained before polypectomy using virtual chromoendoscopy alone or with dye-based chromoendoscopy. Primary outcome was the negative predictive value (NPV) for neoplasia of high-confidence optical diagnosis among diminutive (¿ 5 mm) rectosigmoid lesions. Histology was the reference standard.
Results: Of 147 rectosigmoid lesions, 128 were diminutive. In 103 of the 128 lesions (81 %), the optical diagnostic confidence was high and showed an NPV of 96.0 % (95 % confidence interval [CI] 88.9 %-98.6 %) and accuracy of 89.3 % (95 %CI 81.9 %-93.9 %). By following the diagnose-and-leave-in policy, we would have avoided 59 % (75/128) of polypectomies at the expense of two diminutive low grade dysplastic adenomas and one diminutive sessile serrated lesion that would have been left in situ.
Conclusion: In patients with Lynch syndrome, the diagnose-and-leave-in strategy for diminutive rectosigmoid polyps would be feasible and safe.

1. ESGE/ESGAR recommend computed tomographic colonography (CTC) as the radiological examination of choice for the diagnosis of colorectal neoplasia. Strong recommendation, high quality evidence. ESGE/ESGAR do not recommend barium enema in this setting. Strong recommendation, high quality evidence.2. ESGE/ESGAR recommend CTC, preferably the same or next day, if colonoscopy is incomplete. The timing depends on an interdisciplinary decision including endoscopic and radiological factors. Strong recommendation, low quality evidence. ESGE/ESGAR suggests that, in centers with expertise in and availability of colon capsule endoscopy (CCE), CCE preferably the same or the next day may be considered if colonoscopy is incomplete. Weak recommendation, low quality evidence.3. When colonoscopy is contraindicated or not possible, ESGE/ESGAR recommend CTC as an acceptable and equally sensitive alternative for patients with alarm symptoms. Strong recommendation, high quality evidence. Because of lack of direct evidence, ESGE/ESGAR do not recommend CCE in this situation. Very low quality evidence. ESGE/ESGAR recommend CTC as an acceptable alternative to colonoscopy for patients with non-alarm symptoms. Strong recommendation, high quality evidence. In centers with availability, ESGE/ESGAR suggests that CCE may be considered in patients with non-alarm symptoms. Weak recommendation, low quality evidence.4. Where there is no organized fecal immunochemical test (FIT)-based population colorectal screening program, ESGE/ESGAR recommend CTC as an option for colorectal cancer screening, providing the screenee is adequately informed about test characteristics, benefits, and risks, and depending on local service- and patient-related factors. Strong recommendation, high quality evidence. ESGE/ESGAR do not suggest CCE as a first-line screening test for colorectal cancer. Weak recommendation, low quality evidence.5. ESGE/ESGAR recommend CTC in the case of a positive fecal occult blood test (FOBT) or FIT with incomplete or unfeasible colonoscopy, within organized population screening programs. Strong recommendation, moderate quality evidence. ESGE/ESGAR also suggest the use of CCE in this setting based on availability. Weak recommendation, moderate quality evidence.6. ESGE/ESGAR suggest CTC with intravenous contrast medium injection for surveillance after curative-intent resection of colorectal cancer only in patients in whom colonoscopy is contraindicated or unfeasible. Weak recommendation, low quality evidence. There is insufficient evidence to recommend CCE in this setting. Very low quality evidence.7. ESGE/ESGAR suggest CTC in patients with high risk polyps undergoing surveillance after polypectomy only when colonoscopy is unfeasible. Weak recommendation, low quality evidence. There is insufficient evidence to recommend CCE in post-polypectomy surveillance. Very low quality evidence.8. ESGE/ESGAR recommend against CTC in patients with acute colonic inflammation and in those who have recently undergone colorectal surgery, pending a multidisciplinary evaluation. Strong recommendation, low quality evidence.9. ESGE/ESGAR recommend referral for endoscopic polypectomy in patients with at least one polyp ¿6 mm detected at CTC or CCE. Follow-up CTC may be clinically considered for 6-9-mm CTC-detected lesions if patients do not undergo polypectomy because of patient choice, comorbidity, and/or low risk profile for advanced neoplasia. Strong recommendation, moderate quality evidence. Source and scope This is an update of the 2014-15 Guideline of the European Society of Gastrointestinal Endoscopy (ESGE) and the European Society of Gastrointestinal and Abdominal Radiology (ESGAR). It addresses the clinical indications for the use of imaging alternatives to standard colonoscopy. A targeted literature search was performed to evaluate the evidence supporting the use of computed tomographic colonography (CTC) or colon capsule endoscopy (CCE). The Grading of Recommendations Assessment, Development and Evaluation (GRADE) system was adopted to define the strength of recommendations and the quality of evidence.

Objective Monitoring established Crohn's disease (CD) through a treat-to-target strategy aims to reduce and prevent long-term bowel damage and disability. Despite the availability of different monitoring techniques, there is a current lack of integrated evidence to guide optimal monitoring in terms of appropriate tools and timing. Pan-intestinal video capsule endoscopy (PCE) enables non-invasive and direct visualization of the entire intestinal tract with proven safety and efficacy. This study aims to generate insights on the value of PCE for monitoring established CD from the physician's perspective. Methods The Nominal Group Technique (NGT) was used to create discussion around pre-defined research questions aimed at identifying target patient populations for PCE, benefits of PCE in terms of improving disease management, comparative benefits of PCE over standard of care, research priorities to ratify the use of PCE, and hurdles to PCE utilization. A NGT panel was held in Brussels, Belgium in October 2018 with 9 gastroenterology experts. Data were collected from multiple rankings of statements to the research questions and analyzed descriptively. Results Consensus indicated that PCE is differentiated from other diagnostic tools, allowing for non-invasive and direct visualization of the luminal intestinal tract in one single procedure. Participants agreed that PCE is beneficial for mapping and grading established CD in all patients, enabling individual and tailored treatment decision-making. Time required to read PCE results was identified as the main utilization hurdle by participants. Well-designed studies are needed to confirm improved outcomes amongst patients with CD managed through a PCE-guided approach. Conclusions This study, using the NGT, generated expert opinion on the value of PCE for monitoring established CD in terms of target patient populations and benefits compared to other diagnostic modalities. Participants perceived PCE to facilitate a treat-to-target strategy for CD management. Further research is needed to support this value perception.

Background: Small Bowel Capsule Endoscopy is the first-choice technique for investigating the majority of small bowel diseases. Its most common complications are related to incomplete examinations and capsule retention. There is no consensus on how patients with previous gastrointestinal surgery should receive the capsule. Objective: The primary endpoint was to compare the rate of complete small-bowel examinations (completion rate) between oral ingestion and endoscopic delivery of the capsule. The secondary endpoint was to compare diagnostic yield and adverse events in the two groups. Methods: A retrospective observational study was conducted in nine hospitals in Spain. Demographic data, previous surgery, indication for capsule endoscopy, intestinal transit time, diagnosis, completion rate (percentage of capsules reaching the caecum), diagnostic yield (percentage of results compatible with indication for the exam) and adverse events were collected. Results: From January 2009 to May 2019 fifty-seven patients were included (39 male, mean age 66 15 years). The most common indications for the exam were "overt" (50.9%) and "occult" (35.1%) small bowel bleeding. Previous Billroth II gastrectomy and Roux-en-Y gastric bypass were present in 52.6% and 17.5% of patients respectively. The capsule was swallowed in 34 patients and placed endoscopically in 23 patients. No significant differences were observed between the oral ingestion and endoscopic delivery groups in terms of completion rate (82.4% vs. 78.3%; p= 0.742), diagnostic yield (41.2% vs. 52.2%; p= 0.432) or small bowel transit time (301 vs. 377 min, p= 0.118). No capsule retention occurred. Only one severe adverse event (anastomotic perforation) was observed in the endoscopic delivery group. Conclusions: In our case series, there were no significant differences between oral ingestion and endoscopic delivery in terms of completion rate, diagnostic yield or safety. Being less invasive, oral ingestion of the capsule should be the first-choice method in patients with previous gastrointestinal surgery. (C) 2020 Elsevier Espana, S.L.U. All rights reserved.

Obscure gastrointestinal bleeding is defined as bleeding from a source that cannot be identified on upper or lower gastrointestinal endoscopy, being capsule endoscopy the next step in those patients. Some patients may be unsuitable for conventional endoscopy and performing a capsule pan-endoscopic test as a first line procedure might potentially reduce the number of endoscopies and their subsequent risk. The aim of our study was to analyse our experience with capsule endoscopy in the bleeding patient setting. We retrospectively reviewed the first 100 pan-endoscopic capsule procedures performed in our centre from August 2011 until December 2016. 61.2% of our patients had positive findings; 46.26% had a previous negative gastroscopy and in 67.7% of them the capsule detected small bowel lesions and in 80.64%, colonic findings. Taking into consideration that our population were high-risk patients (mainly because of comorbidities), and that we use up to 45 ml of sodium phosphate, we analysed sodium, potassium and creatinine changes before and after procedure. The mean "before" values were respectively 140.68, 4.04 and 1.36. The mean "after" values were 140.28, 3.9 and 1.35 (p=n.s) According to our findings in 64.5% of patients with negative gastroscopy no other endoscopic studies would be needed. According to capsule results, in all our study sample, in 68.6% of cases conventional endoscopy could have been avoided. Panendoscopy with capsule may be useful and safe in bleeding high-risk patients, by selecting the patients who need therapeutic endoscopy, avoiding up to 68.6% of diagnostic endoscopies in our series.

INTRODUCTION:
Flexible spectral imaging colour enhancement (FICE) is a form of virtual chromoendoscopy that is incorporated in the capsule reading software and that can be used by reviewers to enhance the delineation of lesions in the small bowel. This has been shown to be useful in the detection of pigmented (ulcers, angioectasias) lesions. However, its application to coeliac disease (CD) images from small bowel capsule endoscopies (SBCEs) has rarely been studied.
METHODS:
This was a European, multicentre study that included 5 expert capsule reviewers who were asked to evaluate a number of normal and abnormal de-identified images from SBCEs of patients with CD to determine whether the use of FICE and blue light can improve the detection of CD-related changes.
RESULTS:
Sensitivity and specificity of conventional white light in the delineation of CD-related changes were 100%. The next best image modification was FICE 1 with a sensitivity of 80% and a specificity of 100%. There was no difference between conventional white light, FICE and blue light for the identification of CD-related changes. There was a low agreement (Fleiss kappa 0.107; p = 0.147) between expert reviewers in selecting the best image modification that detected CD-related changes.
CONCLUSIONS:
FICE and blue light were not found to be superior to conventional white light in the delineation of macroscopic changes related to CD on SBCEs.

BACKGROUND & AIMS: Dye-based pancolonic chromoendoscopy is recommended for colorectal cancer surveillance in patients with Lynch syndrome. However, there is scarce evidence to support its superiority to high-definition white-light endoscopy. We performed a prospective study assess whether in the hands of high detecting colonoscopists, high-definition, white-light endoscopy is noninferior to pancolonic chromoendoscopy for detection of adenomas in patients with Lynch syndrome. METHODS: We conducted a parallel controlled study, from July 2016 through January 2018 at 14 centers in Spain of adults with pathogenic germline variants in mismatch repair genes (60% women; mean age, 47 +/- 14 years) under surveillance. Patients were randomly assigned to groups that underwent high-definition white-light endoscopy (n = 128) or pancolonic chromoendoscopy (n = 128) evaluations by 24 colonoscopists who specialized in detection of colorectal lesions in high-risk patients for colorectal cancer. Adenoma detection rates (defined as the proportion of patients with at least 1 adenoma) were compared between groups, with a noninferiority margin (relative difference) of 15%. RESULTS: We found an important overlap of confidence intervals (CIs) and no significant difference in adenoma detection rates by pancolonic chromoendoscopy (34.4%; 95% CI 26.4%-43.3%) vs white-light endoscopy (28.1%; 95% CI 21.1%-36.4%; P = .28). However, pancolonic chromoendoscopy detected serrated lesions in a significantly higher proportion of patients (37.5%; 95% CI 29.5-46.1) than white-light endoscopy (23.4%; 95% CI 16.9-31.4; P = .01). However, there were no significant differences between groups in proportions of patients found to have serrated lesions of 5 mm or larger (9.4% vs 7.0%; P = .49), of proximal location (11.7% vs 10.2%; P = .68), or sessile serrated lesions (3.9% vs 5.5%; P = .55), respectively. Total procedure and withdrawal times with pancolonic chromoendoscopy (30.7 +/- 12.8 minutes and 18.3 +/- 7.6 minutes, respectively) were significantly longer than with white-light endoscopy (22.4 +/- 8.7 minutes and 13.5 +/- 5.6 minutes; P <.001). CONCLUSIONS: In a randomized parallel trial, we found that for Lynch syndrome surveillance, high-definition white-light endoscopy is not inferior to pancolonic chromoendoscopy if performed by experienced and dedicated endoscopists.

Background and AimThe role of capsule endoscopy (CE) in established celiac disease (CD) remains unclear. Our objective was to analyze the usefulness of CE in the suspicion of complicated CD. MethodsThis was a retrospective multicenter study. One hundred and eighty-nine celiac patients (mean age: 46.616.6, 30.2% males) who underwent CE for alarm symptoms (n=86, 45.5%) or non-responsive CD (n=103, 54.5%) were included. Diagnostic yield (DY), therapeutic impact and safety were analyzed. ResultsCapsule endoscopy was completed in 95.2% of patients (small bowel transit time: 270.5100.2min). Global DY was 67.2%, detecting atrophic mucosa (n=92, 48.7%), ulcerative jejunoileitis (n=21, 11.1%), intestinal lymphoma (n=7, 3.7%) and other enteropathies (n=7, 3.7%, six Crohn's disease cases and one neuroendocrine tumor). The DY of CE was significantly higher in patients presenting with non-responsive disease compared to patients with alarm symptoms (73.8% vs 59.3%, P=0.035). The new findings of the CE modified management in 59.3% of the cases. There were no major complications. ConclusionCapsule endoscopy may be a moderately helpful and safe diagnostic tool in the suspicion of complicated CD, modifying the clinical course of these patients.

Capsule endoscopy (CE) has become a first-line noninvasive tool for visualisation of the small bowel (SB) and is being increasingly used for investigation of the colon. The European Society of Gastrointestinal Endoscopy (ESGE) guidelines have specified requirements for the clinical applications of CE. However, there are no standardized recommendations yet for CE training courses in Europe. The following suggestions in this curriculum are based on the experience of European CE training courses directors. It is suggested that 12 hours be dedicated for either a small bowel capsule endoscopy (SBCE) or a colon capsule endoscopy (CCE) course with 4 hours for an introductory CCE course delivered in conjunction with SBCE courses. SBCE courses should include state-of-the-art lectures on indications, contraindications, complications, patient management and hardware and software use. Procedural issues require approximately 2 hours. For CCE courses 2.5 hours for theoretical lessons and 3.5 hours for procedural issued are considered appropriate. Hands-on training on reading and interpretation of CE cases using a personal computer (PC) for 1 or 2 delegates is recommended for both SBCE and CCE courses. A total of 6 hours hands-on session-time should be allocated. Cases in a SBCE course should cover SB bleeding, inflammatory bowel diseases (IBD), tumors and variants of normal and cases with various types of polyps covered in CCE courses. Standardization of the description of findings and generation of high-quality reports should be essential parts of the training. Courses should be followed by an assessment of trainee's skills in order to certify readers' competency.

AIM To analyze the diagnostic yield (DY), therapeutic impact (TI) and safety of capsule endoscopy (CE). METHODS This is a multi-centre, observational, analytical, retrospective study. A total of 163 patients with suspicion of celiac disease (CD) (mean age = 46.4 +/- 17.3 years, 68.1% women) who underwent CE from 2003 to 2015 were included. Patients were divided into four groups: seronegative CD with atrophy (Group-I n = 19), seropositive CD without atrophy (Group-II, n = 39), contraindication to gastroscopy (Group-III, n = 6), seronegative CD without atrophy, but with a compatible context (Group-IV, n = 99). DY, TI and the safety of CE were analysed. RESULTS The overall DY was 54% and the final diagnosis was villous atrophy (n = 65, 39.9%), complicated CD (n = 12, 7.4%) and other enteropathies (n = 11, 6.8%; 8 Crohn's). DY for groups I to IV was 73.7%, 69.2%, 50% and 44.4%, respectively. Atrophy was located in duodenum in 24 cases (36.9%), diffuse in 19 (29.2%), jejunal in 11 (16.9%), and patchy in 10 cases (15.4%). Factors associated with a greater DY were positive serology (68.3% vs 49.2%, P = 0.034) and older age (P = 0.008). On the other hand, neither sex nor clinical presentation, family background, positive histology or HLA status were associated with DY. CE results changed the therapeutic approach in 71.8% of the cases. Atrophy was associated with a greater TI (92.3% vs 45.3%, P < 0.001) and 81.9% of the patients responded to diet. There was one case of capsule retention (0.6%). Agreement between CE findings and subsequent histology was 100% for diagnosing normal/other conditions, 70% for suspected CD and 50% for complicated CD. CONCLUSION CE has a high DY in cases of suspicion of CD and it leads to changes in the clinical course of the disease. CE is safe procedure with a high degree of concordance with histology and it helps in the differential diagnosis of CD.

Small bowel capsule endoscopy represents a significant advance in the investigation of the small bowel, allowing direct visualization of this section of the gastrointestinal system. More recently, new video capsules have been released, specifically designed to investigate the esophagus and the colon. In June 2006, Given Imaging Ltd received marketing clearance from the US FDA for the Rapid Access Real-Time (RT) and Rapid Access software. The Rapid Access RT is a handheld device that enables real-time viewing during capsule endoscopy procedures. To date, the clinical benefits of this device are unknown as studies on the Rapid Access RT system have not yet been published. However, it appears that the Rapid Access RT system may reduce the examination and reading time, and may impact significantly in cases where it is important to know the precise localization of the capsule (during PillCam ESO ingestion procedures, PillCam Colon examinations or when delayed gastric transit is suspected) or in case of severe gastrointestinal bleeding (when a therapeutic procedure is required urgently).

Background and Aims: It is known that sodium picosulfate-magnesium citrate (SPMC) bowel preparations are effective, well tolerated and safe, and that split-dosing is more effective for colon cleansing than previous-day regimens. Anesthetic guidelines consider that residual gastric fluid is independent of clear liquid fasting times. However, reluctance to use split-dosing persists. This may be due to limited data on residual gastric fluid volumes (RGFVs) and split-dosing bowel preparations, and that these may not be perceived as standard clear liquids. Furthermore, no studies are available on RGFV/residual gastric fluid pH (RGFpH) and SPMC. We aimed to evaluate the cleansing effectiveness and the RGFV/RGFpH achieved after an SPMC split-dosing regimen compared with a SPMC previous-day regimen.
Methods: This was a single-center observational study. A total of 328 outpatients scheduled for simultaneous EGD and colonoscopy and following a split-dosing or previous-day regimen of SPMC were included. We prospectively measured colon cleanliness by using the Ottawa Bowel Preparation Scale, RGFV, and RGFpH.
Results: Ottawa Bowel Preparation Scale scores for overall, right, mid-colon, and colon fluid were significantly better in the split-dosing group. In the split-dosing group, the 3- to 4-hour fasting time consistently achieved the best cleansing quality. RGFV was significantly lower in the split-dosing group (11.09 vs 18.62, P < .001). No significant differences in RGFpH were detected.
Conclusions: Split-dosing SPMC provides higher colon cleansing quality with lower RGFVs than previous-day SPMC regimens. SPMC in split-dosing acts exactly as a standard clear liquid acts, and thus anesthetic guidelines on this issue may be applied with no concerns.

In an average-risk screening population, technically adequate capsule colonoscopy identified individuals with 1 or more conventional adenomas 6 mm or larger with 88% sensitivity and 82% specificity. Capsule performance seems adequate for patients who cannot undergo colonoscopy or who had incomplete colonoscopies. Additional studies are needed to improve capsule detection of serrated lesions. Clinicaltrials.gov number: NCT01372878.

CE-related AEs are uncommon and difficult to predict by imagiological examinations. SB retention, that is usually asymptomatic, is the most frequent AE. In absence of symptoms, non-surgical management of CE-related AEs is recommended.

Background and objectives: recently, Olympus developed a new prototype (XCF-Q180AY2L) with responsive insertion technology (RIT), which besides the still known variable stiffness technology, included a passive bending section and a new high force insertion tube. Our objective was to investigate whether the use of this prototype could ease colonoscope insertion, increasing the cecal intubation rate, and/or shortening the cecal intubation time.
Material and methods: the study was designed as a prospective observational study in 305 consecutive patients from a colo-rectal cancer screening program. We compared colonoscopies performed with conventional colonoscopes (CFH180AL/CFQ160L) with those performed with the prototype XCF-Q180AY2L. End points were mean cecal and terminal ileal intubation times, cecum intubation rate, and need for specific maneuvers. All colonoscopies were performed under sedation with intravenous propofol. Finally, 288 patients were included.
Results: no complications were observed. Complete cecal intubation rate was 100 % in both groups. The ileum could be reached in 98.95 % of cases. Mean time required to reach the cecum was shorter in the prototype endoscope group (4.31 min, SD 2.63 min) than in the conventional endoscope group (4.66 min, SD 2.52 min) (p < 0.05). Compared with the standard colonoscope group, we observed in the prototype group less subjective sensation of difficulty in the passage of the sigma (p < 0.01), fewer maneuvers when it proved necessary to straighten the scope (p < 0.01), and less frequent need to modify the stiffness of the endoscope (p < 0.05).
Conclusion: we concluded that the prototype endoscope (XCF-Q180AY2L) facilitated colonoscope insertion, requiring slightly less time to reach the cecum than a standard colonoscope.

IM: To evaluate the long-term natural history of the gastroduodenal lesions secondary to extrahepatic embolization with Ytrium 90(Y-90) spheres.
METHODS: From September 2003 to January 2012, 379 procedures of liver radioembolization(RE) using resin microspheres loaded with Y-90 were performed in our center. We have retrospectively compiled the data from 379 RE procedures performed in our center. We report a comprehensive clinical, analytical, endoscopic and histologic long-term follow-up of a series of patients who developed gastroduodenal lesions after the treatment.
RESULTS: Six patients(1.5%) developed gastrointestinal symptoms and had gastrointestinal lesions as shown by upper endoscopy in the next 12 wk after RE. The mean time between RE and the appearance of symptoms was 5 wk. Only one patient required endoscopic and surgical treatment. The incidence of gastrointestinal ulcerations was 3.75%(3/80) when only planar images were used for the pre-treatment evaluation. It was reduced to 1%(3/299) when single-photon emission computed tomography(SPECT) images were also performed. The symptoms that lasted for a longer time were nausea and vomiting, until 25 mo after the treatment.
CONCLUSION: All patients were free from severe symptoms at the end of follow-up. The routine use of SPECT has decreased the incidence of gastrointestinal lesions due to unintended deployment of Y-90 particles.

Introduction: insufflation with carbon dioxide (CO2) during endoscopies compared to air is associated with a decrease in abdominal discomfort after the examination, because CO2 is readily absorbed through the small intestine and eliminated by the lungs.
Aim: the objective of this randomized clinical trial was to assess the effect of CO2 insufflation on pain and abdominal distension after an ileo-colonoscopy (I) and after an ileo-colonoscopy plus gastroscopy (I+G).
Material and methods: we included a total of 309 patients in the study and all endoscopies were performed under sedation with propofol. Two hundred fourteen patients underwent an I (132 with CO2 / 82 with air) and 95 underwent an I+G (53 with CO2 / 42 with air). Abdominal pain was studied at 10, 30 and 120 minutes of exploration and abdominal perimeter difference before and after the procedure.
Results: both in group I and in group I+G, the use of CO2 translated into an average of abdominal pain significantly lower (p < 0.05). Similarly, a smaller increase in waist circumference was found among group I and group I+G, in patients where CO2 was used (p < 0.05).
Conclusion: the insufflation of CO2 instead of air during the performance of endoscopy significantly reduces the discomfort and abdominal pain after an ileo-colonoscopy and after a gastroscopy + ileo-colonoscopy.

he identification of risk factors for the development of metachronous lesions allow to calculate, at the time of surgical treatment, an individual prognostic index and to classify patients into three different risk groups. In high and low risk groups, both specificity and accuracy were acceptable for the prognosis of metachronous lesions, being remarkable the negative predictive power of our classification, which could become relevant when planning a different endoscopic follow up of these patients.

Introduction: Colorectal cancer (CRC) can induce an anti-tumoral immune response mediated by T-lymphocytes, which express CD3. Objectives: To analyze the prognostic value of tissue expression of intraepithelial CD3 (CD3I) both overall and in the early tumoral stages. Methods: We revised 251 patients with resected CRC and favorable clinical course. CD3I expression was analyzed by immunohistochemistry. Multivariate analysis was used to analyze the variables independently associated with survival. We analyzed CD3I(+) expression in relation to survival and tumoral progression, both overall and in patients with pTNM(I-II) stage tumors. The sensitivity, specificity, positive and negative predictive values and diagnostic accuracy of CD3I expression were analyzed. Results: A total of 25.9% of patients with CRC were CD3I(+). After a mean follow-up of 74 months, CD3I(+) expression showed a favorable prognostic value for survival in the multivariate analysis (p = 0.045). Survival curves and absence of tumoral progression were more favorable in CD3I(+) cases, both overall (p = 0.009 and p = 0.004, respectively), and in stages I-II (p = 0.029 and p = 0.015). The specificity and positive predictive value of CD3I(+) were as follows: Survival: overall: specificity =0.89; positive predictive value =0.91. Stage (I-II): specificity =0.94; positive predictive value =0.98. Absence of tumoral progression: overall: specificity = 0.89; positive predictive value =0.88. Stage (I-II): specificity =0.92; positive predictive value =0.96. Conclusions: CD3I expression has an favorable independent prognostic value, with statistically significantly higher percentages of survival and absence of tumoral progression. This more favorable outcome is maintained in the less advanced stages (I-II). CD3I expression shows high specificity and positive predictive value. (C) 2012 Elsevier Espana, S.L. and AEEH y AEG.

Dysphagia is a common symptom in neuromuscular junction disorders, but it rarely occurs in isolation or is the presenting feature. We describe a patient presenting with isolated dysphagia to liquids. Electrophysiological studies, such as repetitive nerve stimulation and single-fiber electromyography, were normal. Serum anti-P/Q-type voltage-gated calcium-channel (anti-P/Q-type VGCC) and anti-acetylcholine receptor (AChR ab) antibodies were above the normal range. A computed tomography scan showed a mediastinal mass corresponding to a thymic carcinoma. After chemotherapy, surgical removal of the thymic carcinoma and radiotherapy, the patient no longer complained of dysphagia, AChR ab titers were reduced and anti-P/Q-type VGCC antibodies became negative. To the best of our knowledge, no previous reports of a paraneoplastic myasthenic syndrome related to thymic carcinoma with both anti-P/Q-type VGCC and AChR antibodies have been described.

OBJECTIVE:
To study the possibility of shift toward more proximal sites in colorectal cancer (CRC) after resection of tumors and synchronous lesions.
MATERIAL AND METHODS:
We reviewed 382 resected CRC diagnosed and followed-up with complete colonoscopies. The localization of metachronous adenomas was compared with that of synchronous lesions overall and by sex, tumoral size and the number of synchronous lesions. The frequency of exclusively proximal localization in first-, second- and third-generation metachronous adenomas was compared with that of synchronous adenomas.
RESULTS:
A total of 54.5% of patients with CRC had synchronous adenomas. After a median follow-up of 48 months, with 2.74+/-1.47 colonoscopies/case, 42.4% developed metachronous adenomas, 16.8% second-generation adenomas and 7.3% third-generation lesions. Proximal shift was found in metachronous adenomas in both sexes, independently of tumoral size and the number of initial lesions. The frequency of exclusively proximal localization in adenomas was 21.2% in synchronous lesions, 39.5% in first-generation metachronous adenomas (p=0.0001; OR=2.46 [1.50-3.95]), 42.6% in second-generation metachronous adenomas (p=0.0008; OR=2.77 [1.44-5.31]) and 39.3% in third-generation metachronous lesions (p=0.0003; OR=2.41 [0.97-5.93]).
CONCLUSIONS:
We found a high incidence of synchronous and metachronous adenomas. Metachronous adenomas showed a proximal shift, independently of sex, tumoral size and the number of synchronous lesions. This tendency was maintained in successive generations of metachronous adenomas, thus demonstrating the need to perform complete colonoscopies throughout the postoperative follow-up period.
