Abstract:
Objective To investigate the application value of self-expanding metallic stent (SEMS) implantation under fluoroscopy combined with endoscopy for acute left-side malignant colorectal obstruction. Methods Clinical date of 49 patients with left-side malignant colorectal obstruction who underwent SEMS implantation under fluoroscopy combined with endoscopy were retrospectively analyzed. Results Stents were implanted successfully in 48 patients. The technical success rate was 97.96% (48/49). One patient was transferred to emergency surgery because the guidewire could not pass through the stenosis. After stent implantation, colorectal obstruction relieved in 47 patients, while one patient was transferred to emergency surgery for unimproved obstruction. Postoperative perforation occurred in one patient after stent implantation, while a small amount of blood in excrement were found in 5 patients and then relieved after symptomatic treatment. Stent migration occurred in 2 patients. Totally 21 patients received tumor resection procedure after the symptoms of intestinal obstruction remission, and the success rate of surgery was 100% (21/21). Conclusion SEMS implantation under fluoroscopy combined with endoscopy is safe and effective to alleviate acute left-side malignant colorectal obstruction.
