Recently, endoscopic placement of self-expanding-metal stents(SEMS)has been widely performed for treatment of acute malignant colorectal obstruction. This study aimed to compare the efficacy of SEMS placement as palliative treatment with that of surgical treatment in patients presenting with acute malignant colorectal obstruction.

A retrospective review was performed for 20 patients with unresectable malignant colorectal obstruction who had receivedinsertion of SEMS(n=9)or surgical treatment(n=11)for palliation between July 2006 andM ay 2014.

Patients who hadreceivedSEMS were in poorer clinical condition regarding age andperformance status. Duration of treatment was significantly lesser andthe postoperative date of initial oral intake after intervention was statistically earlier in the SEMS group. SEMS-relatedmorbid ity was foundin only 2 cases of obstruction due to tumor ingrowth; these patients were successfully treatedby reinsertion of SEMS. The prognosis of both groups showedno statistical difference.

Palliative SEMS placement for unresectable colorectal malignant obstruction in patients with more severe clinical condition relieved obstruction without severe morbidity. Palliative SEMS placement could be an alternative to surgery for the treatment of acute unresectable colorectal obstruction.
