Abstract
A 76-year-old man had undergone high anterior resection for stage II rectal cancer. Colonoscopy was performed because the six-year post-surgery follow-up fecal occult blood test was positive. Stage II colon cancer was located 3cm from the anastomosis site toward the oral side. He was referred to our surgery department and underwent low anterior resection and double-barrel transverse colostomy. He did well, and colostomy closure was considered 4 months later. However, we endoscopically incised and dilated because of complete obstruction at the anastomotic site. With axis and direction of oral and anal sides of the transverse colon confirmed under fluoroscopic guidance, the obstructed area was incised with a needle-like knife and balloon dilated despite transverse colon perforation complication concerns. Because structures were not observed post-dilation and progress was satisfactory, colostomy closure was performed. Postoperative complete anastomotic obstruction is rare in recurrent colon cancer. We report a successful endoscopic incision of complete obstruction followed by colostomy closure case.
