Cholecystectomy Concomitant with Laparoscopic Gastric Bypass: A Trend Analysis of the Nationwide Inpatient Sample from 2001 to 2008
Obesity Surgery, 01/06/2012
Worni M et al. – Concomitant cholecystectomy and laparoscopic gastric bypass surgery have decreased significantly over the last decade. Given the higher rates of postoperative complications, reinterventions, mortality, as well as longer hospital stay, concomitant cholecystectomy should only be considered in patients with symptomatic gallbladder disease.
Methods- The authors used data from adults undergoing laparoscopic gastric bypass for obesity from the Nationwide Inpatient Sample.
- The Cochran–Armitage trend test was used to assess changes over time.
- Unadjusted and risk–adjusted generalized linear models were performed to assess predictors of concomitant cholecystectomy and to assess postoperative short–term outcomes.
- A total of 70,287 patients were included: mean age was 43.1 years and 81.6% were female.
- Concomitant cholecystectomy was performed in 6,402 (9.1%) patients.
- The proportion of patients undergoing concomitant cholecystectomy decreased significantly from 26.3% in 2001 to 3.7% in 2008 (p for trend<0.001).
- Patients who underwent concomitant cholecystectomy had higher rates of mortality (unadjusted odds ratios [OR], 2.16; p=0.012), overall postoperative complications (risk–adjusted OR, 1.59; p=0.001), and reinterventions (risk–adjusted OR, 3.83; p<0.001), less frequent routine discharge (risk–adjusted OR, 0.70; p=0.05), and longer adjusted hospital stay (median difference, 0.4 days; p<0.001).
