Colonic prostheses in the palliative treatment of colonic cancer. Our evaluation after 10 years of experience

Abstract

Abstract:

Background: Endoscopic self-expanding metallic colonic stent / prosthesis placement emerges as a therapeutic option for neoplastic colonic obstruction in two situations: palliative treatment and bridge to surgery. This procedure makes it possible to avoid two-stage surgeries and reduce the probability of a definitive colostomy with the consequent deterioration in quality of life and associated complications.

Aim: To report our experience in the placement of colonic prostheses in neoplastic obstruction as palliative treatment in our environment, after 10 years of experience.

Design: Prospective, longitudinal, descriptive and observational.

Method: From August 2008 to December 2019, all patients who received self-expanding metallic colonic stent with palliative intention due to advanced CRC were analyzed by the same group of endoscopists. Demographic and clinical variables, technical success, clinical success, survival, early and late complications, as well as their resolution were analyzed.

Results: A total of 54 self-expanding prostheses were placed. The mean age was 71 years. 85% of the lesions were located in the left colon. 58% of the cases (31 patients) were performed on an outpatient basis. Technical and clinical success was 92% and 98% respectively. With an average survival of 209 days.

Conclusion: These 10 years of experience allow us to conclude that the placement of self-expanding metal prostheses as a palliative treatment for neoplastic colonic obstruction is effective, safe, and can be performed in both an outpatient setting and with a short hospital stay, allowing early oral discharge and feeding. improving the conditions to face a possible palliative chemotherapeutic treatment.
