RESUMEN
BACKGROUND: Laparoscopic sleeve gastrectomy (SG) is the most commonly performed bariatric surgery. The resected gastric segment is routinely sent for pathology evaluation. No formal national recommendation exists that mandates pathology review. We proposed to study the largest histopathologic series in SG patients yet reported. OBJECTIVE: The primary objective of our study was to determine whether a subgroup of patients who underwent bariatric surgery in the northeastern Unites States is more susceptible to having clinically significant pathologic findings that may benefit from routine histopathologic evaluation of the gastric sleeve specimen. SETTING: University hospital. METHODS: A retrospective electronic chart review of patients who underwent SG at a single large academic institution was performed. Patient demographics, body mass index, and histopathologic reports of the gastric specimens obtained during SG were analyzed. RESULTS: The records of 3543 patients were reviewed. A total of 1076 patients had abnormal pathologies, including gastritis (938), follicular gastritis (98), intestinal metaplasia (25), gastrointestinal stromal tumor (12), leiomyoma (1), lymphoma (1), and other malignancy (1). Black and Hispanic patients had a higher incidence of developing gastrointestinal stromal tumor and intestinal metaplasia. A higher incidence of Helicobacter pylori infection among specimens with abnormal pathologies was noted. CONCLUSIONS: The findings of this study call into question the routine use of pathology workup in gastric specimens after SG. Our data suggest that such analysis may be warranted in certain subtypes of patients such as older Black and Hispanic patients in the northeastern United States.

Visceral myopathy is a rare, often misdiagnosed disease characterised by abnormalities in the gastrointestinal smooth muscle layer. Its clinical presentation includes pseudo-obstruction, intestinal dysmotility and spontaneous perforation. We report an atypical case of a 51-year-old man with a history of recurrent small bowel perforations who presented with an acute abdomen. A laparotomy was performed with identification of a distal jejunal perforation. A small bowel resection with end-to-end anastomosis was done. Minimal adhesions were seen intraoperatively despite the patient's multiple prior surgeries. Pathology showed histiocytic inflammation and patchy loss of the muscle layer reflective of visceral myopathy. Genetic testing revealed a variant of uncertain significance in the myosin light chain kinase gene. It is difficult to make a conclusive diagnosis given the patient's clinical presentation closely mimicking other gastrointestinal disorders. However, it is crucial to consider visceral myopathy in patients with recurrent spontaneous intestinal perforations as a differential diagnosis.
