The procedure was defined as technical success when SEMS covered the stricture fully and opened. The procedure was defined as clinical success when the patient tolerated enteral feeding after SEMS placement in patients with a malignant oesophageal stricture.
In patients with malignant colorectal stricture, the procedure was defined as technical success when SEMS covered the stricture fully and opened. Gas and stool discharge after procedure was defined as clinical success.
Assessment of adverse events: After SEMS placement, patients went through endoscopic inspection in case of suspicion of bleeding, persistent pain and/or obstruction. Direct radiography was performed to check for migration, and revision was conducted through endoscopic intervention. Patients went through endoscopic inspection to evaluate ingrowth and overgrowth over suspicion of reobstruction in the GIS during prolonged follow-ups. Routine control imaging or endoscopic control was not performed when patients presented no complaints during follow-up. The surveys of the patients were calculated at time the SEMS is active and the time of death.
Informed consent was obtained from all patients for the procedure and anaesthesia. The procedures were performed under sedation administered by an anaesthesiologist. Patients who underwent only biliary stenting due to malignant biliary obstruction, patients without pathological diagnosis of malignancy or benign aetiology and patients with missing data records were excluded from the study. All consecutive patients except these patients were included in the study.
The study was approved by the Ethics Committee of Health Sciences University Umraniye Training and Research Hospital (Date: 8 April 2021&No: B.10.1.TKH.4.34.H.GP.0.01/99).
