Index Admission Cholecystectomy for Biliary Colic Precludes the Risk of Readmissions with Biliary Complications and should be Standard Treatment

Background Emergency biliary colic admissions can be managed with an index or elective laparoscopic cholecystectomy (LC). Opting to perform an elective LC may have significant repercussions such as the risk of readmissions before operation with further attacks or with biliary complications (e.g. cholecystitis, pancreatitis, choledocholithiasis). The risk of readmission and biliary complications in patients admitted with biliary colic but scheduled for elective surgery has never been investigated. The secondary aim was to compare rates of peri-operative morbidity between the index admission, elective and readmission LC cohorts. Method All patients admitted with a diagnosis of biliary colic over a 5-year period and proceeding to LC were included in the study ( n = 441). The risk of being readmitted and suffering further morbidity whilst awaiting elective LC was investigated. Peri-operative morbidity was compared between the index admission, elective and readmitted LC groups using univariate and multivariate analysis. Results Following a biliary colic admission, the risk of readmission whilst awaiting elective LC is significant (2 months-25%; 10 months-48%). In this group, the risks of subsequent biliary complications (18.0%) and the requirement for ERCP (6.5%) were significant. Patients who are readmitted before LC, suffer a more complicated peri-operative course (longer total length of stay, higher post-operative complications, imaging and readmission). Discussion Index admission LC for biliary colic avoids the significant risk of readmission and biliary complications before surgery and should be the gold standard. Readmitted patients are likely to have higher rates of peri-operative adverse outcomes. Patients should be counselled about these risks.
