| [ Summary ] |
A questionnaire‒based survey was conducted regarding the outcomes in 285 p atients with malignant colorectal obstruction who were treated with self‒expanding metal stenting (SEMS) at 14 centers. Most of the patients (194 [68.1 %]) had primary colorectal cancer, and 86 (30.2 %) patients had non‒colorectal cancer. Additional chemotherapy was administered to 86 (30.2 %) patients. The longest duration for patency of a stent was 31.4 months. A total of 73 (25.6 %) complications occurred, including 38 (13.3 %) re‒obstructions, 14 (4.9 %) perforations, and 19 (6.7 %) migrations.
Colorectal SEMS placement can be used in the palliation of malignant colorectal obstruction and extracolonic malignant obstruction. It is generally safe and effective and has its own advantages and disadvantages over surgery for these indications. During follow‒up, short term and long term morbidities should be kept in mind. There is a need for careful clinical evaluation of each patient who is a candidate for this procedure. |
