Side-to-end anastomosis in a colostomy for acute malignant large-bowel obstruction: Side-to-end anastomosis with a colostomy (STEC procedure)

This report describes the use of side-to-end anastomosis in a colostomy for an acute malignant large-bowel obstruction. A 59-year-old man presented with a colonic obstruction due to advanced descending colon cancer. The preoperative imaging studies revealed a complete obstruction of the descending colon at the site of the splenic flexure, a remarkably dilated transverse colon, and no other metastatic lesions. Side-to-end anastomosis was performed with the colostomy because of the high comorbidity associated with such cases. When the patient’s general condition improved, a stoma closure was performed under local anesthesia. In conclusion, a side-to-end anastomosis with a colostomy (STEC procedure) was found to be a simple, useful, and cost-effective technique for an acute malignant large-bowel obstruction, particularly in a high-risk patient.
