HALLAZGOS HISTOLÓGICOS GÁSTRICOS EN OBESOS MORBIDOS SOMETIDOS A GASTRECTOMÍA VERTICAL LAPAROSCÓPICA: Pathological findings in resected gastric segments after laparoscopic sleeve gastrectomy

Abstract

Background: Laparoscopic sleeve gastrectomy (LSG) is used for the treatment of obesity and may provide gastric tissue for pathological studies. The association of obesity with dyslipidemias, diabetes and cardiovascular disease is of common knowledge. However its association with gastrointestinal diseases and gastritis is less well known. Aim: To analyze the pathological findings of the resected gastric segment during LSG. Material and Methods: Two hundred fifty patients aged 37 ± 12 years and with a body mass index of 37.7 ± 3.1 kg/m² (189 women), subjected to LSG, were included in a prospective protocol. Resected gastric segments were sent for a pathological study. Results: A gastric disease was identified in 220 (88%) cases. Chronic follicular gastritis was diagnosed in 117 patients (46.8%), chronic superficial gastritis in 76 (30.4%), chronic nonspecific gastritis in 38 (15.2%), intestinal metaplasia in 14% (5.6%) and in one case (0.4%) an early gastric carcinoma. Helicobacterpylori was present in 34 (13.6%) patients. Conclusions: This study shows a high prevalence of histopathological gastric lesions detected after the LSG, reaffirming the need for detection of these lesions before surgery.
