RESUMEN
AIMS: This study aimed to determine readmission rates, causes for readmission and outcomes for patients undergoing elective Laparoscopic Cholecystectomy (LC) without intraoperative cholangiogram (IOC). METHODS: Timing related to readmissions was grouped as <6 weeks, 6 weeks-1 year, 1-2 years and >2 years. Outcomes and variables related to readmission were evaluated. RESULTS: 101 readmissions (6.6) were noted amongst 1523 consecutive LC. The median follow up was 4 years (range 1.6-6.4 years). There was no difference in the median age (48 vs. 53 years, P = 0.2) and sex of the patients between the readmitted and no readmission groups. The incidence of readmissions (n = 101) within the first 6 weeks, 6 weeks-1 year, 1-2 years and >2 years were 2.8%, 1.5%, 1.4% and 0.7% respectively. The most common reasons for readmissions were non-specific abdominal pain (NSAP) (36%), obstructive jaundice (14%), peptic ulcer disease (10%), intra-abdominal collection (4%) and bile leak (3%), pancreatitis (3%), and other reasons (30%). Overall, 24 (22%) of readmissions were related to biliary problems, the majority of these occurred (15/24, 63%) within 6 weeks of LC. The incidence of retained stones within the first 6 weeks, 6 weeks-1 year, 1-2 years and >2 years were 0.4%, 0.3%, 0.1% and 0% respectively. Overall 14 (14%) patients were readmitted with retained stones and all were managed by ERCP & ductal clearance. CONCLUSIONS: Readmission rate following elective LC is low with the majority occurring within the first 6 weeks and only a quarter of these related are directly to biliary pathology. In the absence of routine IOC, around 1% of patients present with retained stones within 2 years of LC. A small fraction of patients continue to suffer from NSAP and should be warned prior to the surgery.
