title: Long-term outcome of endoscopic colorectal stenting for malignant and benign disease.
abstract: Although the technical success rate of endoscopic stenting has been defined, there is a paucity of outcome data. The purpose of this study was to evaluate the long-term results of colorectal stenting for both malignant and benign disease. A retrospective review was conducted of patients who underwent stenting at a tertiary center over 4 years. One surgeon performed all stents under endoscopic and fluoroscopic guidance. A total of 49 stent procedures were performed in 36 patients (19 females, mean age 65 years). Mean follow-up was 15 months. Twenty-eight patients (78%) underwent stenting for malignant disease and eight patients (22%) for benign conditions. The most common reason for intervention was obstruction (81%). Technical success rate was 72 per cent. Carcinomatosis was associated with a higher technical failure rate. Procedural related complications occurred in two patients (6%). Long-term stent migration rate was 24 per cent and was more common in patients with benign disease and patients who received nonmetal stents or stents with diameter < 25 mm. Endoscopic reintervention was required in 33 per cent of patients with initial technical success. Long-term need for subsequent operative intervention was 14 per cent. Endoscopic stenting is a viable option for a select group of patients with colorectal disease. Patient's selection and stent choice influence outcome.
