Abstract
A 69-year-old man, complaining of abdominal pain, was admitted to our hospital. He has a past history of gastrectomy for a hemorrhagic gastric ulcer 30 years previously. We performed an emergency operation, as abdominal enhanced CT revealed a “target sign” of the small intestine in the left, upper abdomen, which represented the ongoing intussusception of the jejunum. We found that the reconstruction after gastrectomy had been made in the Billroth II manner with a Braun’s anastomosis, and that the efferent distal jejunum from the Braun's anastomosis had invaginated the afferent loop toward the remnant stomach through the Braun's anastomosis in a retrograde fashion. No lesions, such as tumors, likely to cause the intussusceptions could be recognized. A Hutchinson procedure was performed. The patient’s postoperative course was uneventful without recurrence. We report herein on this rare case of retrograde intussusception of the jejunal loop through a Braun’s anastomosis, and review the relevant Japanese literature.
