A Case of Intussusception due to Inverted Meckel.s Diverticulum with Lipoma

We report a case of adult intussusception due to inverted Meckel's diverticulum with lipoma, accompanied by idiopathic intussusception. A 34-year-old man with intermittent abdominal pain was found in enhanced abdominal CT to have multiple concentric ring signs of the intestines, diagnosed as ileoileal intussusception, necessitatingemergency surgery. After confirming the presence of two separate intussusceptions laparoscopically, we made a minimal 5cm incision at an appropriate site. The anal one shrank completely. The oral one, includingthe tumor, was resected after it had been shrunk as much as possible. Subserosal lipoma was located at the base of the inverted Meckel's diverticulum. Two such simultaneous intussusceptions are extremely rare.
