A 75-year-old man complained of lower abdominal pain for a week. Obstructive colorectal cancer was suspected by abdominal CT, and the patient was hospitalized immediately. A transanal ileus tube was inserted during emergency surgery to avoid colostomy. All circumference stenosis was observed, and the inflow of contrast medium to the oral side was not confirmed. Adenocarcinoma was reported in the biopsy results. Depression was insufficient, and a self-expandable metallic stent (SEMS) was placed on the 3rd day of hospitalization. After placing the SEMS (Wall FlexTM 90 mm) , the patient was scheduled to receive elective surgery and left our hospital. A temporary radical operation (laparoscopic low anterior resection and D3 lymph node dissection) was performed on the 24th day after hospitalization. Observations of the resected specimen showed that the SEMS covered the lesion without perforation, and that the SEMS expansion was sufficient. In conclusion, we experienced a case of obstructive colorectal cancer applicable to the temporary radical operation and avoided emergency surgery by inserting a SEMS. We report this case with some literature review.
