A Case of Postoperative Intussusception after Laparoscopic Sigmoidectomy Using Double Stapling Technique

Abstract

A case of postoperative intussusception after laparoscopic sigmoidectomy using double stapling technique (DST) in a 64-year-old man is reported. The patient, who had undergone laparoscopic sigmoidectomy, presented with abdominal pain and was admitted to our hospital 24 days after surgery. Computed tomography and colonoscopy showed intussusception at the previous anastomosis site using DST. Emergent laparoscopic surgery was performed because reduction without resection was thought to be impossible. Resection and re-anastomosis were completed. The patient's postoperative recovery was uneventful, and he was discharged after tolerating full oral intake and return of bowel function. Pathological investigation showed edema and fibrosis of the mucosa, but no lead point lesion was observed. To the best of our knowledge, this is the first case report of postoperative intussusception of an anastomosis using DST. Clinicians should be aware of intussusception as a rare complication of anastomosis using DST, and early diagnosis and intervention can lead to less invasive treatment.
