Introduction
Sleeve gastrectomy is the most commonly performed bariatric operation globally. The main complication is GERD. In the medium term, it can increase the incidence of Barrett’s esophagus (BE), which is a risk factor for esophageal adenocarcinoma. Following conventional sleeve gastrectomy, BE is noted in up to 16% of patients postoperatively. Recently, Nissen sleeve gastrectomy (NSG) has been shown to reduce the frequency of postoperative GERD compared to conventional sleeve gastrectomy. This study aims to evaluate the impact of NSG on the incidence and remission of BE in the long term.
Material and Method
This bicentric retrospective study included 692 patients who received NSG from September 2013 to July 2021. All patients underwent preoperative upper GI endoscopy and were then scheduled to receive upper GI endoscopy between 1 and 2 years and then between 3 and 5 years postoperatively. BE was systematically confirmed by biopsies.
Results
Seventy-four patients had endoscopic suspicion of BE, which was confirmed on 54/692 patients by histology. The BE lesions consisted of 18.5% intestinal metaplasia and 75.9% fundal metaplasia. Among these 54 patients, 38 underwent endoscopic investigation within 2 years postoperatively. The biopsies showed healed BE in 25/38 patients (64.1%). At 5 years, two patients had proven BE. Concerning the incidence of BE post NSG: 234 performed the follow-up endoscopy within 2 years. The incidence of de novo BE is nil.
Conclusion
The NSG is associated with healing of known BE in approximately two-thirds of patients at 2-year follow-up. This is consistent with the GERD improvement that has been shown with NSG.
