Abstract: Objective: To evaluate outcomes of palliative surgery for malignant bowel obstruction (MBO) and identify factors associated with postoperative survival. Methods: We retrospectively reviewed 27 patients who underwent palliative surgery for MBO between April 2014 and March 2023. Clinical data including symptom relief, oral intake, discharge status, and overall survival (OS) were analyzed. Results: Median age was 70 years; 23 patients were Stage IV. Primary tumors included colon-rectum (15), stomach (6), pancreas (2), and others (4). Peritoneal dissemination was present in 18 cases. Median preoperative Palliative Prognostic Index (PPI) was 3.0. Postoperative symptom relief was achieved in 96.3%, oral intake in 81.5%, and discharge in 51.9%. Median OS was 118 days. Peritoneal dissemination and oral intake status were significantly associated with OS; sex, age, and PPI were not. Conclusion: Palliative surgery may improve outcomes such as symptom relief, oral intake, discharge to preferred care settings, and survival. These findings support its role in advance care planning and enhancing quality of life in patients with terminal cancer.
