Abstract
BACKGROUND: Laparoscopic cholecystectomy (LC) is one of the safest, most commonly performed surgical procedures, but postoperative complications including bile leak, retained stone, cholangitis, and gallstone pancreatitis following LC occur in up to 2.6% of cases and may require readmission with possible endoscopic retrograde cholangiopancreatography (ERCP) intervention. There is a paucity of literature on factors predictive of need for ERCP following LC. The goal of this study is to describe the prevalence and risk factors for readmission with indication for ERCP. METHODS: We queried the ACS/NSQIP 2012-2017 Participant User Files for patients who underwent LC. Patient demographics, comorbidities, operative characteristics, and postoperative outcomes were evaluated. Multivariate logistic regression was used to identify risk factors for readmission with indication for ERCP intervention. RESULTS: Of 275,570 patients, 11,010 (4.00%) were readmitted within the 30-day postoperative period. Among these, 930 (8.44%) were admitted with indication for ERCP intervention. On multivariate regression, readmissions were more likely in older patients, inpatients, and patients with baseline comorbidities, acute preoperative morbidity, and those discharged to care facilities. The use of intraoperative cholangiogram was associated with lower odds of readmission. Less than 10% of readmitted patients had an indication for ERCP. Those who were readmitted with an indication for ERCP were more likely to have undergone emergency surgery, experienced longer operative times, and had elevated preoperative LFTs or gallstone pancreatitis prior to surgery. The risk of 30-day mortality was significantly higher among patients who experienced any complications after their surgery (OR 13.03, 95% CI 10.57-16.07, p < 0.001). CONCLUSIONS: Older patients, patients with greater preoperative morbidity, and those discharged to care facilities were more likely to be readmitted for any reason following laparoscopic cholecystectomy, whereas patients with evidence of complicated gallstone disease were more likely to be readmitted with an indication for ERCP, even when controlling for the use of intraoperative cholangiogram. Initiatives aimed at reducing readmission with indication for ERCP should focus on these patient subgroups.
