Clinical outcomes of self-expandable metal stent (SEMS) placement as palliative treatment for malignant colorectal obstruction: A single-center study from Japan
چکیده انگلیسی


- It is necessary to establish a logistic framework with a mixed team of endoscopists and surgeons to support re-intervention and surgery.
- Colorectal stenting is a valid therapeutic option, palliative SEMS placement is likely to result in re-occlusion within a year of stenting.

ObjectivesWe aimed to assess the efficacy of self-expanding metal stent (SEMS) implantation as palliative treatment for malignant colorectal obstruction.MethodsWe retrospectively reviewed the records of patients with malignant colorectal obstruction who underwent SEMS insertion as palliative treatment in our hospital between March 2013 and December 2016. We analyzed demographic, clinical, and operative characteristics.ResultsA total of 13 patients (8 males, 5 females; median age, 80.1 years) were reviewed. Tumor location included the left colon, rectum, and right colon in 38.5%, 38.5%, and 23% of the patients, respectively. Advanced and early colorectal cancer were noted in 7 (63.6%) and 4 (36.4%) cases, respectively. The mean ColoRectal Obstruction Scoring System score was 0.92 before stenting and 3.92 after stenting. Oral intake was resumed at a median of 2.1 days after SEMS placement. Median stent patency was 7.6 months, and 69.2% of patients maintained stent patency until death or the end of follow-up. Stent-related adverse effects included: re-occlusion (4 cases, 30.8%); stent migration (1 case, 7.7%), and pain with tenesmus (2 cases, 15.4%). In patients with re-occlusion (median follow-up interval, 1.3 months), stent patency was maintained for a median of 10.3 months (early failure, within 3 months; late failure, >11 months).ConclusionSEMS placement as a palliative treatment is likely to fail within a year, leading to re-occlusion. It is very important to maintain vigilant monitoring using X-ray, CT, and colonoscopy after SEMS placement, with close cooperation between the endoscopist and surgeon. A logistic framework involving careful follow-up, even in the absence of symptoms, and a combined team involving endoscopists and surgeons should be established to support re-intervention and surgery. We recommend vigilant monitoring of patients who received SEMS placement for palliation of malignant colorectal obstruction.
