    Abstract:
    BACKGROUND: Limited data are available regarding early postoperative small bowel obstruction (SBO) after laparoscopic Roux-en-Y gastric bypass (LRYGB). The aim of the present study was to review our experience with early SBO after LRYGB. The setting was a tertiary referral bariatric center. METHODS: We reviewed a prospectively maintained database to assess the diagnosis, management, and outcomes of patients who underwent surgery for SBO within 30 days of LRYGB. RESULTS: From April 2004 to December 2011, 2126 patients underwent LRYGB. Of these patients, 11 (.5%) required surgical management for early SBO. Of the 11 patients, 9 were women and 2 were men. with a mean age of 53 years (range 35-70) and mean body mass index of 45 kg/m(2) (range 38-65). The average interval from LRYGB to the presentation of SBO was 5.0 days (range 2-15). All early SBOs were diagnosed by computed tomography with oral contrast. The causes of early SBO included kinking at the jejunojejunostomy in 4, an intraluminal blood clot near the jejunojejunostomy in 2, angulation of the Roux limb in 1, mesenteric hematoma in 1, intra-abdominal hematoma in 1, obstruction of common channel in 1, and pelvic adhesions from previous surgery in 1. Diagnostic laparoscopy was attempted in all patients. Four patients required conversion to open surgery. Postoperative complications developed in 5 patients; no patient died. Laparoscopic management of early SBO resulted in fewer complications than the open approach. CONCLUSION: Early SBO after LRYGB is uncommon; however, a prompt diagnosis and surgical intervention are important to prevent additional morbidity. The ability to complete the reoperation laparoscopically varies with the etiology and location of the obstruction.
