Background:
The prevalence of cholelithiasis correlates with obesity. Patients often present for bariatric surgery with symptomatic cholelithiasis. There is a concern of cross-contamination when performing laparoscopic adjustable gastric banding (LAGB) with concurrent cholecystectomy. The primary goal of this study is to address the safety and feasibility of this practice.
Methods:
A retrospective cohort study was designed from a prospectively collected database. All LAGB patients from July 2005 to April 2013 were included. Patients undergoing LAGB with concurrent cholecystectomy comprised the study group (LAGB/chole). The control group (LAGB) consisted of patients undergoing LAGB alone, and was selected using a 3:1 (control:study) case-match based on demographic and comorbidity data. The primary outcome was overall complication rate, with secondary outcomes including operating room (OR) time, length of stay (LOS), 30-day readmission/reoperation, erosion, infection, and band/port revisional surgery.
Results:
There were 4,982 patients who met criteria. Of these, 28 patients had a LAGB with concurrent cholecystectomy, comprising the LAGB/chole (study) group. The remaining 4,954 patients were eligible controls, of which 84 were selected for the LAGB (control) group. Demographic and comorbidity data, along with mean follow-up time, were similar between the two groups. OR time was longer in the LAGB/chole group, but LOS was the same. The overall complication rate in the LAGB/chole group was 21 (n = 6) versus 20% (n = 17) in the LAGB group (p = 0.893). Thirty-day readmission and reoperation were similar. There was also no difference in port site, wound, and intra-abdominal infections. There were no band erosions in either group.
Conclusions:
Performing a concurrent cholecystectomy at the time of LAGB does not result in increased immediate or delayed morbidity. Although longer to perform, this safe operation would avoid a second surgery for a patient already diagnosed with symptomatic cholelithiasis.
