Vertical Gastric Bypass with Fundectomy: Feasibility and 2-Year Follow-Up in a Series of Morbidly Obese Patients

Roux-en-Y gastric bypass (RYGB) is the gold standard procedure for morbid obesity and its results are well known and largely discussed. The major limitation of the procedure is the difficult exploration of the excluded gastric pouch and duodenum. The vertical gastric bypass with fundectomy was recently introduced in attempt to overcome these limitations. To date, its effectiveness is debated and outcomes still unclear. The purposes of this study were to describe the vertical gastric bypass with fundectomy and to analyse its outcomes in term of weight loss, complications, and comorbid resolutions. Since January 2012 to July 2014, 30 consecutive patients were enrolled and prospectively followed for a 24-month period. All patients underwent the vertical gastric bypass with fundectomy. Follow-up visits were scheduled at 7 days, 1, 6, 12, and 24 months, or whenever necessary. Overall, 24 women and six men were enrolled in the study. Mean preoperative BMI was 38.2 +/- 8.5 kg/m(2). No intraoperative complications were reported. Postoperative overall complication rate was 10%. Compliance to the 24-month follow-up was 100%. Mean BMI and excess weight loss (EWL%) were significantly lower compared to baseline (p < 0.05). Comorbid improvement or resolution was recorded in the 80% of the patients. Vertical gastric bypass with fundectomy is feasible and effective with similar results in terms of weight loss, complications, and comorbid improving compared to the classic RYGB. Complete evaluation of the gastric anatomy and easy access to the main duodenal papilla are unquestionable advantages.
