Laparoscopic Undo of Fundoplication with Roux-en-Y Gastric Bypass in a Morbidly Obese Patient with Prior Nissen's Fundoplication: A Video Report.

BACKGROUND: Roux-en-Y gastric bypass (RYGB) may be a better option for morbidly obese patients with gastroesophageal reflux (GERD) for long-term reflux control. It is recommended after fundoplication if a patient is morbidly obese with GERD with failed fundoplication or if bariatric surgery is planned with a prior successful fundoplication (Kim et al., Am Surg 80(7):696-703, 2014; Kambiz Zainabadi, Surg Endosc. 22(12):2737-40, 2008). Complete takedown of the wrap to avoid stapling over the fundoplication creating an obstructed, septated pouch is needed (Kambiz Zainabadi, Surg Endosc. 22(12):2737-40, 2008). The aim of this video was to demonstrate the technical aspect of dissection and undo of Nissen's fundoplication followed by performance of a RYGB in a morbidly obese patient with GERD with prior successful Nissen's fundoplication opting for bariatric surgery after a year.

METHODS: We present a case of a 50-year-old woman with a BMI of 36.14 with previous laparoscopic Nissen's fundoplication for severe GERD (controlled after surgery) and a prior laparoscopic intraperitoneal onlay mesh repair who presented for bariatric surgery 1 year after fundoplication. She was successfully treated by laparoscopic undo of the fundoplication with RYGB.

RESULTS: In this multimedia high-definition video, we present step-by-step the laparoscopic undo of a Nissen's fundoplication followed by RYGB. The procedure included lysis of all adhesions between the liver and the stomach, dissection of the diaphragmatic crura, complete takedown of the wrap, repair of the hiatal hernia, creation of a gastric pouch, creation of an antecolic Roux limb, gastrojejunal anastomosis, and jejuno-jejunal anastomosis.

CONCLUSION: Laparoscopic RYGB after fundoplication in morbidly obese patients with GERD is a technically difficult but feasible option.
