This study suggests that OAGB with a Nissen antireflux valve may be a safe and effective surgical technique, reducing the risk of postoperative reflux for patients with preexisting hiatal hernia.
Introduction: The realization of an antireflux valve according to the Nissen technique during the operation of one-anastomosis gastric bypass (OAGB) may theoretically decrease the incidence of postoperative reflux in patients with hiatal hernia (HH). Material and Methods: In this retrospective study, we included all patients operated on between January 2015 and January 2019 for an OAGB associated with the creation of an antireflux Nissen valve (360-degree wrap). The patients included had type II or type III HH that had been diagnosed preoperatively or discovered intraoperatively. Results: Twenty-two patients were operated on during the period considered. The mean preoperative BMI was 40 +/- 14 kg/m(2). Five patients (22.7%) had a history of bariatric surgery. Typical symptoms of gastroesophageal reflux disease (GERD) were preoperatively present in four patients (18%), and HH was revealed preoperatively only in four patients; for all the other patients, the diagnosis of HH was made intraoperatively. The rate of early and/or late postoperative complications was 0%. The mean duration of follow-up was 23 +/- 15 months. No dysphagia was reported during follow-up. Three patients presented with symptomatic GERD postoperatively, including one de novo. Mean BMI at the end of follow-up was 24 +/- 3 kg/m(2), and the % of total weight loss was 108 +/- 30%. Conclusions: OAGB with a Nissen antireflux valve seems to be a safe and effective surgical technique and it could be an extra arrow in the surgeon's quiver in the presence of HH in a patient scheduled for OAGB.
