title: A Review of Sleeve Gastrectomy Specimen Histopathology.
abstract: With the increasing popularity of sleeve gastrectomy, many stomach specimens are being evaluated. Understanding the significance and treatment for unexpected pathology is important. This study examines the incidence of relevant histopathology of sleeve gastrectomy specimens. It evaluates previous data for each histopathology and provides recommendations for treatment. In this study, a retrospective review was performed for 241 patients who underwent sleeve gastrectomy from 2009 to 2014 at a single institution. Of the specimens, 122 had no significant histopathology, 91 had gastritis, 13 had lymphoid aggregates, 5 had hyperplasia, 3 had intestinal metaplasia, 3 had gastrointestinal stromal tumors (GISTs), and 3 had gastric polyps. Of the GISTs all had a low mitotic rate and the size of the tumor ranged from 1.5 to 4.5 cm. The findings of metaplasia may be a marker for increased risk of malignancy and may require additional surveillance. The findings of GIST may warrant interval imaging to survey for recurrence, though the likelihood of recurrence for the tumors in this study is less than 2 per cent based on previous studies.
