Histopathology findings of resected gastric specimens post sleeve gastrectomy: A cross-sectional study

Background: Sleeve gastrectomy is a safe and feasible bariatric procedure, but it is debatable whether the resected gastric specimen should be sent for histopathological examination. This is based on whether examination would reveal any serious findings in the absence of suggestive clinical symptoms. In this study, we aim to look for the percentage of examined resected gastric specimens and identify the prevalence of various histopathological findings among patients who underwent sleeve gastrectomy, comparing our results to the literature.Materials and methods: A retrospective cross-sectional study. Histopathology reports were retrieved for patients who underwent sleeve gastrectomy between January 2015 and October 2019. Data was collected from their medical records and analysed.Results: A total of 810 patients underwent sleeve gastrectomy in the study period. The majority of them (88.9%, n = 720) had their specimens sent for pathological examination. Female patients were 585 (77.5%), their mean age was 36 +/- 10.7 (mean +/- SD) years and body mass index was 46 +/- 7.5 (mean +/- SD) kg/m(2). Chronic gastritis was detected in 88.3% of the patients (n = 636), H. Pylori related gastritis was present in 50.3% of the patients (n = 362), intestinal metaplasia (2.2%, n = 16), gastric atrophy (0.4%, n = 3), and dysplasia (0.1%, n = 1), none had malignancy.Conclusion: This is the largest study in the area examining resected gastric specimens post sleeve gastrectomy. Most sleeve gastrectomy patients had chronic gastritis in their resected gastric specimens, and half of it is attributed to H. Pylori microorganism, only one had dysplasia.
