Abstract
A 59-year-old man was admitted to our hospital for a feeling of weakness and abdominal pain. He had a history of appendectomy and laparotomy for ileus 38 years ago. He was found to be anemic. Colonoscopy revealed multiple ulcerations with two fistulas, which ran in the longitudinal direction, in the transverse colon. Barium enema revealed dilation of the lumen of the transverse colon and fistulous openings from a dilated ileum and a contracted ileum. The patient was diagnosed with blind loop syndrome due to ileocolic side-to-side anastomosis, and laparotomy was performed. The ileocolic anastomosis was resected and the short circuit was released. Annular strictures of the proximal and the distal ileum were seen at the anastomotic site, and histological examination revealed erosion in the mucosa and acute peritonitis at the anastomotic site of the ileum. Endoscopic diagnosis, such as diagnosis of ileal strictures, was important because blind loop syndrome by short circuit of the small intestine and colon is an indication for surgical removal of the short circuit.
