Chronic Fistula Post Laparoscopic Nissen Sleeve Gastrectomy. Conversion to Roux-en-Y Gastric Bypass
Background: Sleeve gastrectomy (SG) is the most frequently performed bariatric intervention worldwide, and obese patients have a higher risk of developing reflux symptoms compared with the general population [1, 2]. One of the controversies of SG is to perform it in patients with gastroesophageal reflux disease (GERD). Some studies have shown that SG may exacerbate GERD symptoms or even increase the risk of “de novo” postoperative GERD [3, 4]. Laparoscopic Nissen fundoplication is an effective treatment for patients with severe GERD.
