Palliative Gastroenterostomy in Malignant Gastric Outlet Obstruction: A Single-Center, Single Surgical Team Experience

Background: Malignant gastric outlet obstruction (GOO) is a common complication of stomach, pancreas, and periampullary region tumors, causing serious nutritional disorders and loss of quality of life. This study evaluated the clinical data and factors affecting the survival of patients who underwent palliative gastroenterostomy. Methods: Data from 23 patients who underwent palliative gastroenterostomy due to malignant gastric outlet obstruction in our center between June 2020 and January 2025 were analyzed retrospectively. Demographic characteristics, preoperative clinical data, intraoperative findings, and postoperative outcomes of the patients were evaluated. Patients were divided into two groups according to their survival times as below and above 90 days; factors affecting survival were analyzed by Kaplan-Meier curves and Cox regression analyses. Results: Patients who lived longer than 90 days had higher Karnofsky Performance Score, lower Charlson Comorbidity Index, higher albumin level, and preserved electrolyte balance (p
