Abstract

Background Laparoscopic vertical sleeve gastrectomy is used with increasing frequency as a therapeutic option for morbid obesity. Before the procedure, patients undergo a rigorous preoperative evaluation including double contrast upper gastrointestinal radiographic series at our institution. Patients undergoing sleeve gastrectomy are presumed to have no significant gastric pathology. Objectives: To investigate the prevalence of histopathologic findings requiring clinical follow-up in sleeve gastrectomy specimens. Setting: University Hospital, United States. Methods Retrospective review was conducted of all primary vertical sleeve gastrectomy specimens performed for morbid obesity at our institution from July 2008 until August 2012 (N = 248). Results Unanticipated findings warranting clinical follow-up were identified in 8.4% of cases and included cases of H. pylori gastritis, autoimmune gastritis with microcarcinoid formation, necrotizing vasculitis, and intestinal metaplasia. H. pylori was identified in 5.2% of all cases and in 33.3% of cases of gastritis. Neoplasms were identified at laparoscopy in 2 additional cases (0.8%). Conclusions Surgeons and pathologists should be aware of the high prevalence of diagnoses requiring clinical follow-up in vertical sleeve gastrectomy specimens.
