A 44-year-old male complained of abdominal pain was admitted to our hospital. He had been diagnosed as Peutz-Jeghers syndrome and operated three times due to ileus caused by intestinal polyps. His diagnosis was invagination which was treated in the operation with minor wound. Sixty-six polyps ranging in size from 5mm to 40mm were polypectomized or ligated with detachable snare by intraoperative laparoscope-assisted enteroscope.
