| [ Summary ] |
The development of expandable metallic stent endoprosthesis for colorectal obstructions, was some what delayed, compared to other digestive tract procedures for treatment of anatomical peculiaries of the large bowel. However, in the late 1990's, several clinical cases concerning the application of metallic stents for rectal malignant stenosis were reported. Also, insertion of self-expanding stainless steel stents, under colonoscopic observation, for stenosis of large bowel cancer began in November 1993, as a preoperative preparation in our hospital. In this review, we described the history of the clinical literature on metallic stent endoprosthesis for colorectal obstruction. We also described the method of and results from stent endoprosthesis for colorectal cancer(SECC) that we developed. SECC was performed on 34 patients and the rate of insertion was 82% (28 cases) . SECC is a new method for operative preparation of patients with obstructing colorectal cancers, which may reduce morbidity and mortality associated with this difficult problem. This method is noteworthy. An exclusive stent and associated kit are being developed for sale. Development of an exclusive stent for use in the colon or rectum would promote popularization of metallic stent endoprosthesis for colorectal obstruction being popularized as a part of therapeutic endoscopic treatment. |
