Background: Laparoscopic liver surgery has progressively evolved. Consequently, liver procedures are increasingly performed laparoscopically, particularly in experienced centers. However, vascular resection and reconstruction still are considered a limitation for laparoscopy1 due to the risk of bleeding and the technical difficulty. Methods: A 72-year-old woman with a history of colorectal cancer had a 10 cm metastasis diagnosed in the right hemiliver with tumoral invasion of the right portal branch and tumor thrombus advancing to the portal confluence. After adjuvant chemotherapy and with stable disease, surgical resection was planned.2,3 Tips to avoid portal stenosis were carefully followed. Results: The operation was performed with a fully laparoscopic procedure. To minimize manipulation, an in situ right hepatectomy was performed.4 The right hepatic artery was dissected and ligated. The liver transection was guided with a caudal approach of the middle hepatic vein.5 The right biliary duct was then divided, achieving an excellent exposure of the portal bifurcation. The main and left portal trunks were occluded with vascular clamps, and the right portal vein was sharply divided with scissors. The stump was sutured to minimize backflow bleeding and to cover the tumor thrombus. Then, the portal opening was transversally sutured with a 5/0 running suture. The clamps were released, and the authors observed no bleeding and an adequate caliber with no stenosis. The procedure was completed in the standard fashion. The postoperative course was uneventful, and the woman was discharged on postoperative day 3. No early or late complications were observed.6 CONCLUSIONS: In selected cases, patients who require vascular resection and reconstruction during hepatectomies can benefit from the advantages of a laparoscopic approach.

BACKGROUND: Radical re-resection has been demonstrated beneficial in incidental gallbladder cancer (iGBC) stages¿pT1b [1]. Anatomical resection (AR) of segments IVb-V is recommended, particularly for iGBC and liver-sided tumors [2]. Laparoscopically, this is a challenging procedure, as well as the regional lymphadenectomy, since inflammation from previous surgery can hinder identification of extrahepatic bile ducts. This difficult minimally invasive procedure, facilitated with indocyanine green (ICG) fluorescence enhancement [3] is herein didactically demonstrated. METHODS: A 73 y. o. female patient underwent laparoscopic cholecystectomy for cholelithiasis. An iGBC -pT2b with positive cystic node-was found. Completion radical surgery was decided. Before surgery, 1.5mg of ICG was intravenously administered. A regional lymphadenectomy (stations 5-8-9-12-13) was safely performed: ICG allowed for bile duct visualization despite scarring from previous procedure. AR (IVb-V) was performed based on a glissonian-pedicle approach. After completing the procedure, a new dose of ICG was administered to discard ischemic areas in the remnant. RESULTS: Total operative time was 359 min. Intermittent Pringle maneuver resulted in <50 ml bleeding. Hospital stay was 3 days. Pathological examination revealed no residual tumor in the liver bed. Ten lymph nodes were resected; 3 of them (2 retroportal and 1 common hepatic artery) showing tumoral invasion. After surgery, 6 cycles of adjuvant chemotherapy (Gemcitabine-Oxaliplatin) was administered. CONCLUSIONS: Laparoscopic radical surgery (AR of segments IVb-V plus regional lymphadenectomy) for iGBC is feasible and safe [4]. ICG fluorescence can be of help to identify hilar structures and rule out areas of ischemia

Background Liver surgery after radioembolization (RE) entails highly demanding and challenging procedures due to the frequent combination of large tumors, severe RE-related adhesions, and the necessity of conducting major hepatectomies. Laparoscopic liver resection (LLR) and its associated advantages could provide benefits, as yet unreported, to these patients. The current study evaluated feasibility, morbidity, mortality, and survival outcomes for major laparoscopic liver resection after radioembolization. Material and methods In this retrospective, single-center study patients diagnosed with hepatocellular carcinoma, intrahepatic cholangiocarcinoma or metastases from colorectal cancer undergoing major laparoscopic hepatectomy after RE were identified from institutional databases. They were matched (1:2) on several pre-operative characteristics to a group of patients that underwent major LLR for the same malignancies during the same period but without previous RE. Results From March 2011 to November 2020, 9 patients underwent a major LLR after RE. No differences were observed in intraoperative blood loss (50 vs. 150 ml; p = 0.621), operative time (478 vs. 407 min; p = 0.135) or pedicle clamping time (90.5 vs 74 min; p = 0.133) between the post-RE LLR and the matched group. Similarly, no differences were observed on hospital stay ( median 3 vs. 4 days; p = 0.300), Clavien-Dindo = III complications (2 vs. 1 cases; p = 0.250), specific liver morbidity (1 vs. 1 case p = 1.000), or 90 day mortality (0 vs. 0; p = 1.000). Conclusion The laparoscopic approach for post radioembolization patients may be a feasible and safe procedure with excellent surgical and oncological outcomes and meets the current standards for laparoscopic liver resections. Further studies with larger series are needed to confirm the results herein presented.

The purpose of this study is to describe a technical modification that facilitates right liver mobilization in laparoscopic right hepatectomy (LRH). In the supine position, an inflatable device is placed under the patient's right chest. For right hemiliver mobilization, the table is placed in 30A degrees anti-Trendelenburg and full-left tilt. Balloon inflation offers an additional 30A degrees left inclination that places the patient in an almost left lateral position. Foot and lateral supports are placed to prevent patient slippage during changes in the patient positioning. From December 2013 to October 2015, this technique has been used in 10 consecutive LRH. The indications for these procedures were as follows: four donor hepatectomies for living donor liver transplant, three hepatocellular carcinomas and one peripheral cholangiocarcinoma in cirrhotic patients, one hepatocellular carcinoma in a non-cirrhotic patient, and one case of colorectal cancer metastases. In this period, it has also been used to facilitate mobilization and resection in the posterior segments of the liver in seven patients. In every case, right hemiliver mobilization was easily performed in a maximum time of 15 min and placement of a tape or plastic tube for liver hanging was prepared. We have not observed any complication directly attributable to the technique herein described (i.e. right brachialgia; arms, back or left flank pain) in the early or late postoperative follow-up. The additional left inclination obtained with the inflation of a balloon under the right chest facilitates right hemiliver mobilization. Its use may help in the performance and adoption of LRH.

Background. The pure laparoscopic approach in right hepatectomy (LRH) for living donor liver transplantation (LDLT) is a controversial issue. Some authors have reported the procedure to be feasible but surgical outcomes and impact on short and longterm morbidity rates are yet to be determined. The aim of this study is to present the results of a preliminary 5 consecutive cases series of LRH for LDLT and to compare it with a successive cohort of open right hepatectomies (ORH) for LDLT. Methods. From May 2013 to October 2015, 5 consecutive donors underwent LRH for LDLT in our center. The previous last 10 ORH for LDLT were selected for comparison. Special care was taken to include all adverse events. Each patient's complications were graded with the Clavien-Dindo Classification and scored with the Comprehensive Complication Index. Results. All 5 consecutive donors completed a pure laparoscopic procedure. All allografts (open and laparoscopically procured) were successfully transplanted with no primary graft failures. Only 2 Clavien-Dindo Grade-I complications occurred in the LRH donors, while ORH donors had 10 Grade I, 2 Grade II and 1 Grade IIIa complications in the short term (< 3 months). In the long term (6-12 months follow-up), LRH donors had a significant lower incidence of complications (Comprehensive Complication Index: 1.74; SD, 3891 vs 15.2 SD; 8.618; P = 0.006). Conclusions. In our experience, LRH for LDLT is a feasible procedure. Further comparative series may support our preliminary findings of reduced incidence and severity of complications as compared with the open approach.

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.

Background: In this observational study we reviewed the efficacy and side effects of different antiemetic combinations used in our hospital for postoperative nausea and vomiting (PONV) prophylaxis in high-risk women undergoing highly emetogenic surgery. Methods: After reviewing retrospectively the medical records of patients undergoing highly emetogenic elective surgeries under general anaesthesia, we selected 368 women whose Apfel risk score was ¿ 3 and receiving a combination of 2 antiemetics for PONV prophylaxis. We analysed the incidence of PONV at 2, 6, 12 and 24h after surgery, antiemetic rescue requirements, pattern of occurrence of PONV, side effects and level of sedation were also assessed. The main goal was complete response defined as no PONV within 24h after surgery. Results: Ondansetron 4mg i.v. plus dexamethasone 8mg i.v. (O&Dex), haloperidol 1mg i.v. (O&Hal1), haloperidol 2mg i.v. (O&Hal2) or droperidol 1.25mg i.v. (O&Dro) were the combinations most frequently used. The complete response was better in groups O&Dex: 68.5% (CI: 58-78), O&Hal2: 64.1% (CI: 53-74) and O&Dro 63% (CI: 52-73) than in group O&Hal1: 41.3% (CI: 31-52) (p<0,01). Peak incidence of PONV occurred within the 2-6h period. The incidence of side effects was higher in group O&Hal2. Conclusion: In high risk patients for PONV who underwent highly emetogenic surgeries, the efficacy of low-dose haloperidol (1mg) in combination is limited. Higher doses (2mg) are more effective but its use is associated with a high incidence of side effects.
