Abstract
We analyzed 15 small intestine tumors in the past 10 years. 10 of them were malignant and 5 were benign tumors. All cases were symptomatic, and 11 cases were diagnosed before the operation. All benign tumors were revealed by preoperative diagnosis, and laparoscopic surgery was performed. Successful preoperative diagnosis of small intestine tumors has been possible thanks to recent advances in the diagnostic imaging field. Because the small intestine is a flexible organ, when the lesion can be localized, laparoscopic surgery can be easily performed. Among the malign tumors, 1 was a smooth muscle sarcoma, 1 a gastrointestinal stromal tumor, 2 were malignant lymphomas, and 6 were small intestine adenocarcinomas. We performed open surgery in 9 of the 10 malignant tumors, because of the size or invasion of the tumors. Because small intestine malignant tumors have poor prognosis, an early detection is important.
