657. COMPARISON BETWEEN GASTRIC TUBE AND COLOPLASTY IN ESOPHAGECTOMY AND ESOPHAGEAL BYPASS IN ESOPHAGEAL STENOSIS DUE TO INGESTION CORROSIVE SUBSTANCE

Abstract

Abstract The treatment of ingestion of caustic agents is controversial in the literature. Surgical therapy has been shown to be the best way to proceed, but the surgical methodology has been varied according to the patient's involvement. This study aims to expose the experience of a single institution in relation to the methodology used for the surgical treatment of esophageal stenosis by ingestion of a caustic substance. A retrospective study was carried out in which data were collected from 27 patients who underwent a surgical procedure for the treatment of esophageal stenosis due to alkali ingestion at the Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo between 2010 and 2019 and their subsequent comparison between the conduits used in the surgical intervention. Fisher's test was performed to compare the groups regarding cervical leakage and post-surgical symptoms with a significance level of 5%. Of the 27 surgical procedures for esophageal stenosis due to alkali ingestion, 12 performed gastric conduits and 15 colon conduits. When comparing the groups regarding cervical leaks, no statistically significant difference was noted (p = 0.7060). There were also no statistically significant differences regarding the presence of symptoms in the postoperative period (p > 0.99...) Surgical intervention by both gastric and colon conduits showed no differences in cervical leakage and symptom control. Surgical intervention by both gastric and colon conduits showed no differences in cervical leakage and symptom control.
