Objective: To evaluate the feasibility and clinical value of endoscopic interventional treatment of malignant gastrointestinal obstruction.
Methods: With the aid of X ray, 32 cases with malignant gastrointestinal obstruction were treated with endoscopic metal stenting. There were 8 cases with gastric outlet obstruction, 7 with duodenal obstruction, 13 with rectal obstruction, and 4 with sigmoid obstruction.
Results: Among the 32 patients, metal stenting was successfully performed in 30 cases (93.7%, and obstructive symptoms were relieved within 1-3 days. Metal stent placement was permanent in 15 cases with gastric outlet or duodenal obstruction. Twelve cases with colorectal obstruction received stent placement as palliative treatment, while other 3 cases underwent subsequent elective surgical resection. Metal stent placement failed in one case with recurrent rectal carcinoma, and perforation occurred in another one case with wide spread metastatic sigmoid colon carcinoma and Hartmann operation was performed. During the follow-up period, no stent migration was detected.
Conclusion: Endoscopic interventional treatment of malignant gastrointestinal obstruction is a feasible, safe, effective and well tolerated method. It can reduce the patients trauma and pain, and improve the quality of life.
