Background:
s/Aims: Given the high mortality associated with gallbladder cancer (GBC), the efficacy of adjuvant therapy (AT) remains controversial. We audited our data over an 11-year period to assess the impact of AT.
Methods:
This study included all patients who underwent curative resection for GBC from 2007 to 2017. Analyses were conducted of clinicopathological characteristics, surgical details, and postoperative therapeutic records. The benefits of adjuvant chemotherapy (CT) or chemoradiotherapy (CTRT) were evaluated against surgery alone using SPSS version 20 for statistical analysis.
Results:
The median age of patients (n = 142) was 50 years. The median overall survival (OS) was 93, 34, and 30 months with CT, CTRT, and surgery alone respectively (p = 0.612). Multivariate analysis indicated that only disease stage and microscopically involved margins significantly impacted OS and disease-free survival (DFS). CT showed increased effectiveness across all prognostic subsets, except for stage 4 and margin-positive resections. Following propensity score matching, median DFS and OS were higher in the CT group than in the CTRT group, although the differences were not statistically significant (p > 0.05).
Conclusions
Radically resected GBC patients appear to benefit more from adjuvant CT, while CTRT should be reserved for cases with high-risk features.

BACKGROUND/AIMS: This study was aimed at determining the factors associated with the development of benign biliary stricture (BBS) in patients who had sustained a bile duct injury (BDI) at cholecystectomy and developed bile leaks. METHODS: A retrospective analysis of 214 patients with BDI who were referred to our center between January 1989 and December 2009 was done. RESULTS: One hundred fifty-three (71%) patients developed BBS (group I), and 61 (29%) were normal (group II). By univariate analysis, female gender (p=0.02), open cholecystectomy as the index operation (p=0.0001), delay in the referral from identification of injury (p=0.04), persistence of an external biliary fistula (EBF) beyond 4 weeks (p=0.0001), EBF output >400 mL (p=0.01), presence of jaundice (p=0.0001), raised serum total bilirubin level (p=0.0001), raised serum alkaline phosphatase level (p=0.0001), and complete BDI (p=0.0001) were associated with the development of BBS. Furthermore, open cholecystectomy as the index operation (p=0.04), delayed referral (p=0.02), persistent EBF (p=0.03), and complete BDI (p=0.001) were found to predict patient outcome in the multivariate analysis. CONCLUSIONS: For the majority of patients with BDI, the risk of developing BBS could have been predicted at the initial presentation.

BACKGROUNDS/AIMS: Mirizzi's syndrome (MS) poses great diagnostic and management challenge to the treating physician. We presented our experience of MS cases with respect to clinical presentation, diagnostic difficulties, surgical procedures and outcome. METHODS: Prospectively maintained data of all surgically treated MS patients were analyzed. RESULTS: A total of 169 MS patients were surgically managed between 1989 and 2011. Presenting symptoms were jaundice (84%), pain (75%) and cholangitis (56%). Median symptom duration s was 8 months (range, <1 to 240 months). Preoperative diagnosis was possible only in 32% (54/169) of patients based on imaging study. Csendes Type II was the most common diagnosis (57%). Fistulization to the surrounding organs (bilio-enteric fistulization) were found in 14% of patients (24/169) during surgery. Gall bladder histopathology revealed xanthogranulomatous cholecystitis in 33% of patients (55/169). No significant difference in perioperative morbidity was found between choledochoplasty (use of gallbladder patch) (15/89, 17%) and bilio-enteric anastomosis (4/28, 14%) (p=0.748). Bile leak was more common with choledochoplasty (5/89, 5.6%) than bilio-enteric anastomosis (1/28, 3.5%), without statistical significance (p=0.669). CONCLUSIONS: Preoperative diagnosis of MS was possible in only one-third of patients in our series. Significant number of patients had associated fistulae to the surrounding organs, making the surgical procedure more complicated. Awareness of this entity is important for intraoperative diagnosis and consequently, for optimal surgical strategy and good outcome.
