Colonic stents in colorectal obstruction.
Obstruction is the presenting symptom of colorectal cancer in up to 40 per cent of patients. Benign strictures and other neoplasms including lymphoma and gynecologic tumors occur as well. Emergent operative therapy is often suboptimal and associated with significant morbidity and mortality. Our objective was to review our experience with stent placement for colonic obstruction. Seven patients underwent stent placement for a total of eight procedures. There were three patients with unresectable colorectal cancer, two patients with metastatic gynecologic cancer, one patient with rectal lymphoma, and one patient with metastatic cancer of unknown primary. All colonic stents were Wallstents placed by the same endoscopist under fluoroscopic and endoscopic guidance. Stents were successfully placed in all patients without complication. One patient underwent placement of two stents in succession for a long stenosis. Six of seven patients (86%) had resolution of the obstruction and return of bowel function. Five of seven were tolerating a diet within 24 hours. One patient's mental status did not allow for oral intake. Four patients were discharged within 48 hours. Two patients died within the same hospitalization as a result of metastatic disease. One patient was found to have multilevel disease requiring stoma placement. There was no morbidity or mortality associated with stent placement, and 86 per cent of patients had palliation of the obstruction. We conclude that colonic stent placement is a safe and effective therapy for colorectal obstruction at this institution.
