RESUMO
Background: Liver re-transplantation (re-LT) represents the only treatment for patients with irreversible graft failure. Objective: The aim of the current study was to describe the outcomes of both, patient and graft, after re- LT, at a high-volume referral center. Methods: Our population consisted of patients, with liver disease, who underwent re-LT in our institution between January 1996 and December 2019. Results: 49 patients met the inclusion criteria. The patient's overall survival (OS) for the first year was 85% (Confidence Intervals (CI) 71-92) and 70% at five years (CI 53-82). In our population, three (6.12%) patients presented loss of graft and were included again in the transplant list; of these, one agreed to a new transplant while the remaining two died. This gave us graft survival results similar to those obtained for the re-LT patient; 85% at one year (CI 71-92) and 70% at 5 years (CI 53-82). Conclusion: Our study shows that re-LT is a valid and safe treatment for both early graft dysfunction and for transplanted patients who again present end-stage liver disease, showing a satisfactory long-term evolution, with parameters comparable to primary transplantation.
RESUMO
BACKGROUND: Laparoscopic liver resections (LLR) have been increasingly performed in recent years. Most of the available evidence, however, comes from specialized centers in Asia, Europe and USA. Data from South America are limited and based on single-center experiences. To date, no multicenter studies evaluated the results of LLR in South America. The aim of this study was to evaluate the experience and results with LLR in South American centers. METHODS: From February to November 2019, a survey about LLR was conducted in 61 hepatobiliary centers in South America, composed by 20 questions concerning demographic characteristics, surgical data, and perioperative results. RESULTS: Fifty-one (83.6%) centers from seven different countries answered the survey. A total of 2887 LLR were performed, as follows: Argentina (928), Brazil (1326), Chile (322), Colombia (210), Paraguay (9), Peru (75), and Uruguay (8). The first program began in 1997; however, the majority (60.7%) started after 2010. The percentage of LLR over open resections was 28.4% (4.4-84%). Of the total, 76.5% were minor hepatectomies and 23.5% major, including 266 right hepatectomies and 343 left hepatectomies. The conversion rate was 9.7%, overall morbidity 13%, and mortality 0.7%. CONCLUSIONS: This is the largest study assessing the dissemination and results of LLR in South America. It showed an increasing number of centers performing LLR with the promising perioperative results, aligned with other worldwide excellence centers.

BACKGROUND: The role of intraoperative cholangiography (IOC) in the diagnosis, prevention and management of bile duct injury (BDI) remains controversial. The aim of the present study was to determine the value of routine IOC in the diagnosis and management of BDI sustained during laparoscopic cholecystectomy (LC) at a high-volume centre. METHODS: A retrospective analysis of a single-institution database was performed. Patients who underwent LC with routine IOC between October 1991 and May 2012 were included. RESULTS: Among 11,423 consecutive LCs IOC was performed successfully in 95.7 per cent of patients. No patient had IOC-related complications. Twenty patients (0.17 per cent) sustained a BDI during LC, and the diagnosis was made during surgery in 18 patients. Most BDIs were type D according to the Strasberg classification. The sensitivity of IOC for the detection of BDI was 79 per cent; specificity was 100 per cent. All injuries diagnosed during surgery were repaired during the same surgical procedure. Two patients developed early biliary strictures that were treated by percutaneous dilatation and a Roux-en-Y hepaticojejunostomy with satisfactory long-term results. CONCLUSION: The routine use of IOC during LC in a high-volume teaching centre was associated with a low incidence of BDI, and facilitated detection and repair during the same surgical procedure with a good outcome.
