A 79-year-old man with a history of four surgeries for colorectal cancer, intestinal obstruction, stomach cancer, and choledocholithiasis underwent a fifth surgery for recurrent intestinal obstruction. Surgery consisted of partial resection of the small intestine segment containing the site of obstruction and reconstruction with end-to-end anastomosis. After surgery, a drain was placed for intraabdominal abscess caused by ruptured suture in the cecum on the anal side. Subsequently, dilatation developed and expanded from the small intestine near the abscess site presumably because of the development of stricture due to inflammation. Decompression by using an ileus tube did not improve the patient's condition, but to avoid a difficult surgery due to severe adhesions, we performed balloon dilation using single-balloon enteroscopy, which successfully improved the intestinal obstruction. The patient has been well with no sign of stricture for the past 1 year as of this writing.
