Intrathoracic Sleeve Migrations After Sleeve Gastrectomy: A Compilation of Case Reports.

Laparoscopic sleeve gastrectomy (LSG) is the most commonly performed bariatric procedure in the United States. Postoperative migration of the stomach into the chest is a rare complication of this procedure. In this study, we present a compilation of acute and chronic intrathoracic sleeve migrations (ITSMs) after LSG and present possible underlying mechanisms of this complication, as described in the literature. We retrospectively reviewed the preoperative, intraoperative, and postoperative course of patients who had an ITSM after LSG between 2011 and 2019. Two patients presented with this complication in the acute setting, whereas 3 patients developed ITSM as a chronic issue years after the primary procedure. All 5 were female patients, with a mean age and body mass index of 55.6 ± 9.5 (years) and 37.8 ± 2.9 kg/m, respectively. None of the cases had a hiatal hernia repair during the initial operation. All cases were completed laparoscopically with reduction of the migrated sleeve into the abdomen and primary hiatal hernia repair. One case required a return to the operating room for an acute reherniation. In this article, we report a compilation of cases of ITSMs after LSG with distinct clinical features that highlight the diversity of possible reasons and risk factors for its development.
