Impact on sleeve gastrectomy in patients with esophageal motor disorder.

Abstract

Gastroesophageal reflux disease (GERD) and esophageal motor disorders (EMD) are frequent conditions among patients with obesity. The effects of sleeve gastrectomy (SG) on esophageal function can worsen GERD, but little is known about its effects on EMD and the consequences of preexisting EMD on GERD after SG. To study the postoperative outcomes of SG in a population of patients displaying preexisting EMD. University Hospital, France. Patients with EMD confirmed by high-resolution manometry who underwent a laparoscopic SG between 2010 and 2019 were retrospectively included in this monocenter study. GERD symptoms and high-resolution manometry results were recorded before surgery and during follow-up. Conversion to gastric bypass were also recorded. Thirty-seven patients were included. Mean age was 52.6 ± 12.9 years. Most patients were female (70%). EMD were achalasia (19% of patients), hypercontractile (22%), hypocontractile (30%) and nutcracker esophagus (22%), and ineffective esophageal motility (8%). GERD symptoms were present in 10 patients (27%) preoperatively and 18 (49%) postoperatively. Achalasia was not resolved after SG and was constantly associated with disabling food blockage or GERD symptoms after surgery, and 3 of 4 patients with nutcracker esophagus had postoperative GERD symptoms and underwent gastric bypass. This study is the largest to describe the course of GERD and EMD after SG in patients displaying preoperative EMD. Achalasia and nutcracker esophagus are associated with poorer postoperative outcomes, and another procedure such as a gastric bypass should be performed.
