IntroductionSelf-expanding metal stents (SEMS) can be used as a bridge to surgery (BTS) or for palliation in the treatment of malignant large bowel obstruction. This case series evaluates the short-term outcomes of SEMS and success rates over time.MethodsA total of 75 consecutive patients who underwent colonic stenting for malignant colonic obstruction over a period of six years were included. This time period was subdivided into two equal parts for analysis. The procedure was carried out by a single surgeon from a tertiary institution in Singapore.ResultsTechnical success was reported in 93.3% of cases and clinical success in 81.3% of cases, with better success rates in the second half of the study (89.2% vs. 73.7%; p < 0.05). There were seven cases of inadequate decompression and two cases of colonic perforation. The median duration from stent insertion to surgery was ten days, and the median postoperative length of stay was six days.ConclusionSEMS are a safe and effective way of relieving malignant large bowel obstruction, including those that are proximal. The improvement in success over time reflects the importance of having an experienced endoscopist carry out the procedure to ensure optimum success rates.Copyright: © Singapore Medical Association.
