Background
Preoperative evaluation and treatment of biliary lithiasis in morbid obese patients who are candidates to bariatric surgery raise a series of questions which to date has no clear consensus. The aim of this study was to evaluate the results of routine preoperative abdominal ultrasonography and selective cholecystectomy comparing patients who underwent laparoscopic Roux-en-Y gastric bypass (RYGBP) with and without simultaneous cholecystectomy.
Methods
The prospective database of all the patients who underwent laparoscopic RYGBP in our institution was reviewed. The demographic characteristics, comorbidities, operative time, hospital stay, and postoperative complications were analyzed.
Results
From August 2001 to December 2006, 1,311 patients underwent laparoscopic RYGBP, 137 (10.4%) of them were excluded due to previous cholecystectomy. In 128 (10.9%) of the remaining 1,174 patients, a cholecystectomy associated to laparoscopic RYGBP was performed. The mean age was 38.5 ± 10.1 years, and 106 (82.8%) were women. The mean operative time in patients with and without simultaneous cholecystectomy was 129.8 ± 45 and 108.5 ± 43 min, respectively (p < 0.001). The hospital stay was 3.6 ± 0.8 days in patients with simultaneous cholecystectomy and 4 ± 3 days in patients without simultaneous cholecystectomy (p = 0.003). There were no deaths. Postoperative complications were observed in 9 (7%) and 73 (6.9%) patients with and without simultaneous cholecystectomy respectively (p = NS). Postoperative complications were not related to the cholecystectomy.
Conclusion
Cholecystectomy associated to laparoscopic RYGBP should be considered in all patients with preoperative ultrasound diagnosis of cholelithiasis.
