Abstract
A 39-year-old man presented to our hospital because of a 2-week history of lower abdominal pain. Abdominal contrast-enhanced computed tomography revealed ileo-ileal intussusception due to a tumor of the small intestine.
Double-balloon endoscopy and intestinal radiography revealed a so-called penis-like tumor with Kercking's folds at 100 cm proximal to the terminal ileum.
Biopsy of the tumor revealed pyloric gland tissue. We strongly suspected intussusception by inverted Meckel's diverticulum. A single port laparoscopic partial resection of the small intestine was performed. The resected specimen contained a true diverticulum that protruded into the lumen of the small intestine, and ectopic gastric mucosa and pancreatic tissue were found. These results were consistent with the preoperative diagnosis. The postoperative period was uneventful, and after 6 days the patient was discharged. In adults, intussusception due to inverted Meckel's diverticulum is rare. We were able to achieve minimally invasive surgery, due to preoperatively gained definite diagnosis and denial of malignancy. The small intestine is a good adaptation for single port laparoscopic surgery because it is well tolerated and does not require complicated surgical procedure.
