AbstractAbstract PDF
Authors evaluated the accuracy of preoperative pelvic CT scan staging and its effects on management in 12 biopsy proved rectal cancer patients. Authors also studied postoperative CT in 5 patients to detect disease recurrence and metastasis. Preoperative CT staging was identical to surgical and/or pathological staging in 9 patients (75%), but it was underestimated in two cases and overestimated in one instance than in surgical stagings. In 7 cases, CT scan did not alter original choice of procedures. However, preoperative CT staging gave definitive informations to change management plans in 5 cases otherwise the treatment would be difficult and inadequate. Postoperative CT showed local recurrence in one and liver metastases in 2 cases. One of them was not detected at exploratory laparotomy.

AbstractAbstract PDF
Small bowel malignancy consists 1~2% of overall gastrointestinal tract cancer and leiomyosarcomas of small intestine are 10~20% of small bowel malignancy. Small bowel leiomyosarcomas are rare in incidence and have no specific symptoms, signs or definite radiologic findings, so it is not easy to diagnose at early stage of disease. They are found occasionally by unknown origined gastrointestinal bleeding, abdominal pain, intestinal obstruction, perforation and palpable mass, and diagnosed mostly by operation. Recently annual case reports are increasing trend in Korea. We experienced two cases of small bowel leiomyosarcomas which was diagnosed finally by pathologic findings, so we report them with literatural review.
