Beware of the interval cholecystectomy

Area of Science:

• Hepatobiliary Surgery
• Minimally Invasive Procedures
• Surgical Outcomes Research

Background:

• Percutaneous cholecystostomy (PC) use for acute cholecystitis (AC) has surged despite limited data on subsequent interval cholecystectomy (IC).
• The effectiveness and risks of IC, a common follow-up to PC, remain inadequately evaluated.
• This study quantifies the morbidity and mortality associated with interval cholecystectomy.

Purpose of the Study:

• To evaluate the morbidity and mortality rates of interval cholecystectomy (IC) following percutaneous cholecystostomy (PC).
• To identify predictors of difficult IC procedures.
• To compare outcomes of IC with direct cholecystectomy for acute cholecystitis.

Main Methods:

• Retrospective analysis of adult patients undergoing PC and IC between January 2008 and December 2013.
• Comparison of IC outcomes (conversion rate, operative time, complications, mortality) with a cohort undergoing direct cholecystectomy for AC.
• Linear regression analysis to identify predictors of difficult IC.

Main Results:

• Patients undergoing IC were older, had higher American Society of Anesthesia classifications, and more complex AC (Tokyo grade) than those with direct cholecystectomy.
• IC was associated with significantly longer operative times, increased blood loss, higher rates of conversion, surgical site infection, bowel injury, and 1-year mortality.
• Predictors of difficult IC included higher body mass index, longer time from admission to PC, and higher American Society of Anesthesia classification.

Conclusions:

• Interval cholecystectomy following percutaneous cholecystostomy is a challenging procedure with substantial associated morbidity.
• The study identifies key factors predicting operative difficulty, aiding in patient selection and surgical planning.
• Further research is needed to optimize the management of patients undergoing PC and subsequent IC.
