Routine cholecystectomy during laparoscopic biliopancreatic diversion with duodenal switch is not necessary.
Similar to gastric bypass patients, a regimen of ursodeoxycholic acid in the immediate postoperative period might obviate the need for routine cholecystectomy. Routine cholecystectomy has been recommended for patients who undergo biliopancreatic diversion (BPD), because of the high prevalence of gallstones in the obese patient and presumed development of gallstones postoperatively. We have considered elective cholecystectomy only if gallbladder disease were present. The aim of this study was to assess the need for cholecystectomy in the postoperative period in such patients.
In this retrospective study, the data from 219 patients who had undergone BPD with duodenal switch (BPD/DS), from January 1999 to January 2003, were analyzed. We performed a 150-cm alimentary limb and 100-cm common channel BPD/DS. The patients received 600 mg ursodeoxycholic acid orally daily for 6 months. The following data were recorded: demographics, medical history, medication, weight loss, diagnostic evaluation, and operative and pathologic data.
Of the 219 patients who underwent surgery, 59 were men (26.9%) and 160 women were (73.1%) (mean age 41.7 years, mean body mass index 55.7 kg/m(2)). The mean follow-up was 30 months (range 12-48). Of the 219 patients, 57 (19.6%) underwent cholecystectomy: 28 (12.7%) preoperatively, 10 (4.5%) simultaneously, and 19 (8.7%) postoperatively. Simultaneous cholecystectomy was performed when the patient had a history of colic episodes with gallbladder disease (disclosed by preoperative ultrasonography). The postoperative cholecystectomy pathology reports showed cholecystitis in only 7 patients.
The results of our study have shown that the incidence of postoperative cholecystectomy in BPD/DS patients is low, and cholecystitis is rare. Routine cholecystectomy in BPD/DS patients is no longer recommended.
