Purpose: The purpose of this study is to determine the incidence of gastric tube abnormalities after SG and its relationship with esophagitis progression.
Methods: Retrospective study which included 459 patients in the postoperative period of SG who underwent an esophagogastroduodenoscopy in both pre- and postoperative periods. The main studied variables were presence of gastric tube abnormalities (dilation, neofundus, twist, and hiatal hernia) and esophagitis progression.
Results: Among the 459 patients who underwent SG, 393 (85.6%) were women, and 66 (14.4%) men, with mean age of 40.4 years. Mean preoperative BMI was 39.70 kg/m2. In total, 20.3% of the sample presented progression of esophagitis after surgery. Among the whole sample, 130 (28.3%) presented with an abnormality of the remnant gastric tube. The most common alteration was gastric dilation, which occurred in 16.1% of the patients, followed by gastric twist (10.7%), neofundus (7.4%), and hiatal hernia (0.2%). Patients who presented with any abnormality of the gastric tube were significantly prone to presenting esophagitis progression (p = 0.013). When analyzing each morphological abnormality isolated, there was no statistically significant correlation.
Conclusion: Abnormalities of the gastric tube are not uncommon after SG and seems to contribute partially to the relevant rates of GERD and esophagitis after this surgery.
