Abstract:
Background and Objective: Colonic stenting in left-sided tumor is being commonly used. However, placing a stent in the flexure tumors is rare because it is technically more difficult. In this study, we aimed to retrospectively screen patients with flexure tumors admitted to our clinic who were treated using a colonic stent and discuss our findings. Methods: Patients admitted to the emergency department for obstructive colonic tumors between 2012 and 2017 were retrospectively evaluated, and 21 patients treated using stents were included in the study. The expandable metal stent (Wallflex (R), Boston Scientific, Marlborough, MA, USA) was placed at the obstruction through the lead wire. Results: The mean age of the patients was 62 years, and the ratio of females to males was 3: 18. Splenic flexure tumors were detected in 18 patients and hepatic flexure tumors in 3 patients. Seven of the patients were stented for palliative purposes. Fourteen of the cases underwent surgery. Three of them underwent laparoscopic surgery and eleven underwent open surgery. Conclusions: Preoperative stenting in colonic flexura tumors is associated with faster healing, less postoperative complications, lower rates of colostomy, and higher rates of minimally invasive surgery, and can be safely used at experienced centers.
