Superior mesenteric artery (SMA) syndrome is a rare condition in which the duodenum is compressed between the SMA and aorta. This often occurs following extreme weight loss and has been reported in the bariatric population. We present the first reported case of SMA syndrome following sleeve gastrectomy. The patient underwent laparoscopic duodenojejunostomy and recovered uneventfully. The following is a review of the literature and detailed operative approach in the attached video.

Introduction: The laparoscopic adjustable gastric band (LAGB) can be revised to sleeve gastrectomy (LSG) for various reasons. Data are limited on the safety and efficacy of single-stage removal of LAGB and creation of LSG., Methods: A retrospective review of cases was performed from 2010 to 2013. From the primary LSG group, a control group was matched in a 2:1 ratio., Results: Thirty-two patients underwent single-stage revision from LAGB to LSG, with a control group of 64. The most common indication for revision was insufficient weight loss (62.5%). Operative time for revision and control groups was 134 and 92 min, respectively (p < 0.0001). Hospital stay was 3.22 and 2.59 days, respectively (p = 0.02). Overall, the 30-day complication rate for revision and control patients was 14.71 and 6.25%, respectively (p = 0.20). There were no leaks, one stricture (3.13%) in the revision group, and one reoperation for bleeding in the control group (1.56%). For patients with BMI >30 at surgery, change in BMI at 12 months for revision and control was 8.77 and 11.58, respectively (p = 0.02)., Conclusion: Single-stage revision can be performed safely, with minimal increases in hospital stay and 30-day complications. Weight loss is greater in those who undergo primary LSG compared to those who undergo LSG as revision.

Background: Laparoscopic adjustable gastric banding (LAGB) is increasingly requiring revisional surgery for complications and failures. Removal of the band and conversion to either laparoscopic Roux-en-y gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG) is feasible as a single-stage procedure. The objective of this study is to compare the safety and efficacy of single-stage revision from LAGB to either LRYGB or LSG at 6 and 12 months postoperatively.Methods: Retrospective analysis was performed on patients undergoing single-stage revision between 2009 and 2014 at a single academic medical center. Patients were reassessed for weight loss and complications at 6 and 12 months postoperatively.Results: Thirty-two patients underwent single-stage revision to LRYGB, and 72 to LSG. Preoperative BMIs were similar between the two groups (p = 0.27). Median length of stay for LRYGB was 3 days versus 2 for LSG (p = 0.14). Four patients in the LRYGB group required reoperation within 30 days, and two patients in the LSG group required reoperation within 30 days (p = 0.15). There was no difference in ER visits (p = 0.24) or readmission rates (p = 0.80) within 30 days of operation. Six delayed complications were seen in the LSG group with three requiring intervention. At 6 months postoperatively, percent excess weight loss (%EWL) was 50.20 for LRYGB and 30.64 for LSG (p = 0.056). At 12 months, %EWL was 51.19 for LRYGB and 34.89 for LSG (p = 0.31). There was no difference in diabetes or hypertension medication reduction at 12 months between LRYGB and LSG (p > 0.07).Conclusion: Single-stage revision from LAGB to LRYGB or LSG is technically feasible, but not without complications. The complications in the bypass group were more severe. There was no difference in readmission or reoperation rates, weight loss or comorbidity reduction. Revision to LRYGB trended toward higher rate and greater severity of complications with equivalent weight loss and comorbidity reduction. [ABSTRACT FROM AUTHOR]
