Background: Laparoscopic resection is the treatment of choice for colorectal cancer. Rates of conversion to open surgery range between 7% and 30% and controversy exists as to the effect of this on oncologic outcomes. The objective of this study was to analyze what factors are predictive of conversion and what effect they have on oncologic outcomes. Methods: From a prospective database of patients undergoing laparoscopic surgery between 2000 and 2018 a univariate and multivariate analyses were made of demographic, pathologic, and surgical variables together with complementary treatments comparing purely laparoscopic resection with conversions to open surgery. Overall and disease-free survival were compared using the Kaplan-Meier method. Results: Of a total of 829 patients, 43 (5.18%) converted to open surgery. In the univariate analysis, 12 variables were significantly associated with conversion, of which left-sided resection [odds ratio (OR): 2.908; P=0.02], resection of the rectum (OR: 4.749, P=0.014), and local invasion of the tumor (OR: 6.905, P<0.01) were independently predictive factors in the multiple logistic regression. Female sex was associated with fewer conversions (OR: 0.375, P=0.012). The incidence and pattern of relapses were similar in both groups and there were no significant differences between overall and disease-free survival. Conclusions: Left-sided resections, resections of the rectum and tumor invasion of neighboring structures are associated with higher rates of conversion. Female sex is associated with fewer conversions. Conversion to open surgery does not compromise oncologic outcomes at 5 and 10 years.

Background: Laparoscopic resection is the ideal treatment of colon cancer. The aim of the study was to analyze the predictive factors for postoperative complications and their impact on oncologic outcomes in laparoscopic resections in colon cancer.
Materials and Methods: In all patients undergoing elective laparoscopic surgery the number and degree of severity of postoperative complications were recorded and classified according to Clavien-Dindo. A univariate analysis was made of the demographic, surgical, and oncologic variables of patients with and without complications. The statistically significant variables were then entered into a multivariate model. In both groups overall and disease-free survival were analyzed using Kaplan-Meier estimates.
Results: Of 524 patients, 138 (26.3%) experienced some type of complication, 110 less severe (79.7%) and 28 (20.4%) severe. Twenty-nine conversions to open surgery occurred (5.5%) and hospital mortality was 0.2%. In the multivariate analysis, use of corticosteroids [odds ratio (OR): 3.619], oral anticoagulants (OR: 3.49), blood transfusions (OR: 4.30), and conversion to open surgery (OR: 3.93) were significantly associated with the development of complications. However, sigmoid resections were associated with fewer complications (OR: 0.45). Overall 5-year and 10-year survival in both groups, was 83.3%, 74.1%, 76.0%, and 67.1%, respectively (P = 0.18). Disease-free survival at 5 and 10 years, excluding stage IV tumors, was 88.6% and 90.4%, respectively (P = 0.881).
Conclusions: The use of corticosteroids, oral anticoagulants, blood transfusions, and conversion to open surgery are all independent predictive factors of postoperative complications. Sigmoid resections are associated with fewer complications. In laparoscopic resections of the colon, complications do not negatively affect long-term oncologic outcomes.

Background: the standard treatment for locally advanced rectal cancer is neoadjuvant chemo-radiotherapy, surgery and adjuvant chemotherapy. Only 50% of patients receive the adjuvant treatment due to the surgical complications and toxicity of radiotherapy. Recently, neoadjuvant chemotherapy has been investigated in the locally advanced rectal cancer setting, with the aim of guaranteeing an uninterrupted systemic treatment. The objective of the present study was to assess the safety and efficacy of neoadjuvant chemotherapy in locally advanced rectal cancer.
Methods and patients: patients treated with neoadjuvant chemotherapy and surgery were identified from a prospective database of patients with rectal cancer (cII-III). The primary outcomes were the assessment of the number of R0 resections, the degree of pathologic response, patterns of recurrence and overall and disease-free survival. Treatment schedule: patients received 6-8 cycles of oxaliplatin and fluoropyrimides based chemotherapy.
Results: twenty-seven patients who received neoadjuvant chemotherapy were identified. Twenty-six anterior resections and one Hartmann intervention were performed. An R0 resection was performed in 27 (100%) patients and no involvement of the circumferential margin was observed. Complete pathologic response (ypT0N0) was confirmed in four (14.8%) patients.The median follow-up was 35 months (range: 10-81) and four distant recurrences were recorded. Overall and disease-free survival at five years was 85% and 84.7%, respectively. Twenty-seven (100%) patients received all the cycles of chemotherapy, with a mean of six cycles (range 5-8) per patient.
Conclusions: neoadjuvant chemotherapy is a promising alternative in the locally advanced rectal cancer setting and further phase III clinical trials are clearly warranted.

Background: the prognostic value of the number of lymph nodes isolated (< 12 versus >= 12) in the surgical specimen continues to be controversial. In this study, the impact of isolating fewer or more than 12 lymph nodes in stage II colon cancer with a high-risk biologic phenotype was analyzed, such as the presence of perineural invasion.
Methods: all cases of stage II disease (T3-4N0M0) with perineural invasion (PNI+) were retrospectively identified from a prospective database of patients undergoing surgery for colon cancer. The cohort was divided into two groups depending on the number of lymph nodes isolated (< 12 vs >= 12). Apart from clinical and surgical data, the patterns of recurrence, overall (OS) and disease-free survival (DFS) at five and ten years were analyzed.
Results: sixty patients met the inclusion criteria, 31.7 % had < 12 lymph nodes isolated and 68.3 % had more than 12 isolated. There were no clinical or surgical differences between the two groups. OS at five and ten years was significantly lower in the patients with < 12 lymph nodes isolated (84.2 %, 62.7 % vs 94.6 % and 91.6 %, p = 0.01). DFS at five and ten years was 51 % vs 86.5 %, respectively (p = 0.005).
Conclusion: the number of lymph nodes isolated (with a cutoff of 12) in stage II colon cancer with PNI+ has prognostic value and should therefore be borne in mind when planning adjuvant chemotherapy.

COVID-19 is associated with severe coagulopathy. We present three cases of colonic ischemia that can be attributed to the hypercoagulable state related with SARS-CoV2 and disseminated intravascular coagulation. Three males aged 76, 68 and 56 with respiratory distress presented episodes of rectal bleeding, abdominal distension and signs of peritoneal irritation. Endoscopy (case 1) and computed tomography angiography revealed colonic ischemia. One patient (case 2) in which a computed tomography (CT) scan showed perforation of the gangrenous cecum underwent surgery. D-dimer levels were markedly increased (2,170, 2,100 and 7,360 ng/ml) in all three patients. All three patients died shortly after diagnosis.

Background: Current evidence suggests that local anesthetic wound infiltration should be employed as part of multimodal postoperative pain management. There is scarce data concerning the benefits of this anesthetic modality in laparoscopic weight loss surgery. Therefore, we analyzed the influence of trocar site infiltration with bupivacaine on the management of postoperative pain in laparoscopic bariatric surgery.
Methods: This retrospective randomized study included 47 patients undergoing primary obesity surgery between January and September 2014. Laparoscopic gastric bypass was performed in 39 cases and sleeve gastrectomy in 8 cases. Patients were stratified into two groups depending on whether preincisional infiltration with bupivacaine and epinephrine was performed (study group, 27 patients) or not (control group, 20 patients). Visual analogue scale (VAS), International Pain Outcomes questionnaire, and rescue medication records were reviewed to assess postoperative pain.
Results: VAS scores in the study group and sleeve gastrectomy group were lower than those in the control and gastric bypass groups in the first 4 h postoperatively without reaching statistical significance (p > 0.05). VAS scores did not differ in any other period of time. No statistically significant differences in pain perception were registered according to the patient's pain outcomes questionnaire or the need for rescue medication.
Conclusions: The present study did not conclusively prove the efficacy of bupivacaine infiltration by any of the three evaluation methods analyzed. Nevertheless, preincisional infiltration provides good level of comfort in the immediate postoperative period when analgesia is most urgent.

A 75-year-old woman who had undergone pancreatoduodenectomy 19 years earlier was referred to us for investigation of progressive abdominal pain without conclusive preliminary complementary tests. Computed tomography enabled us to identify that the transanastomotic pancreatic stent had migrated distally, resulting in bowel perforation. She underwent surgery and the foreign body was removed.
