- Liver resection for the treatment of post-cholecystectomy biliary stricture with vascular injury(2015) PERINI, Marcos V.; HERMAN, Paulo; MONTAGNINI, Andre L.; JUKEMURA, Jose; COELHO, Fabricio F.; KRUGER, Jaime A.; BACCHELLA, Telesforo; CECCONELLO, IvanAIM: To report experience with liver resection in a select group of patients with postoperative biliary stricture associated with vascular injury. METHODS: From a prospective database of patients treated for benign biliary strictures at our hospital, cases that underwent liver resections were reviewed. All cases were referred after one or more attempts to repair bile duct injuries following cholecystectomy (open or laparoscopic). Liver resection was indicated in patients with Strasberg E3/E4 (hilar stricture) bile duct lesions associated with vascular damage (arterial and/or portal), ipsilateral liver atrophy/abscess, recurrent attacks of cholangitis, and failure of previous hepaticojejunostomy. RESULTS: Of 148 patients treated for benign biliary strictures, nine (6.1%) underwent liver resection; eight women and one man with a mean age of 38.6 years. Six patients had previously been submitted to open cholecystectomy and three to laparoscopic surgery. The mean number of surgical procedures before definitive treatment was 2.4. All patients had Strasberg E3/E4 injuries, and vascular injury was present in all cases. Eight patients underwent right hepatectomy and one underwent left lateral sectionectomy without mortality. Mean time of follow up was 69.1 mo and after long-term follow up, eight patients are asymptomatic. CONCLUSION: Liver resection is a good therapeutic option for patients with complex postoperative biliary stricture and vascular injury presenting with liver atrophy/abscess in which previous hepaticojejunostomy has failed.
- LIVER RESECTION IN BRAZIL: A NATIONAL SURVEY(2018) FONSECA, Gilton Marques; JEISMANN, Vagner Birk; KRUGER, Jaime Arthur Pirola; COELHO, Fabricio Ferreira; MONTAGNINI, Andre Luis; HERMAN, PauloBackground: Liver surgery has developed significantly in the past decades. In Brazil, the interest on it has grown significantly, but there is no study regarding its clinical practice. Despite intrinsic limitations, surveys are well suited to descriptive studies and allow understanding the current scenario. Aim: To provide an overview on the current spread of liver surgery in Brazil, focusing on groups' profile, operative techniques and availability of resources. Method: From May to November 2016, was conducted a national survey about liver surgery profile in Brazil composed by 28 questions concerning surgical team characteristics, technical preferences, surgical volume, results and available institutional resources. The survey was sent by e-mail to 84 liver surgery team leaders from different centers including all regions of the country. Results: Forty-three study participants (51.2%), from all Brazilian regions, responded the survey. Most centers have residency/fellowship programs (86%), perform and do laparoscopic procedures (91%); however, laparoscopy is still responsible for a little amount of surgeries (1-9% of laparoscopic procedures over all liver resections in 39.5% of groups). Only seven centers (16.3%) perform more than 50 liver resections/year. Postoperative mortality rate is between 1-3% in 55% of the centers. Conclusion: This is the first depiction of liver surgery in Brazil. It showed a surgical practice aligned with worldwide excellence centers, concentrated on hospitals dedicated to academic practice.
