Abstract

Small intestinal malignant tumor accounts for about 3% of all malignant tumors in the gastrointestinal tract, among which 13% are leiomyosarcoma (LMS). In addition, epithelioid LMS is of very rare occurrence. As small intestinal malignant tumors are initially asymptomatic and nonspecific, diagnosis is often delayed, and this can lead to large tumor at the time of detection and lead to intussusception. We observed ileocolonic intussusception in an 80-year-old male patient who was admitted to the hospital with a complaint of abdominal pain and palpable mass on right lower quadrant. The laparoscopic ileocecectomy was performed by the emergency operation because of obstruction. The pathologic examination revealed that the epithelioid LMS developed in the terminal ileum was the leading point of intussusception. To the best of our knowledge, laparoscopic surgery for ileocolonic intussusception with epithelioid LMS has not yet been reported.
