目的 :探讨大肠平滑肌肉瘤的临床病理特点和外科治疗问题。方法 :收集和分析 9例大肠平滑肌肉瘤的临床资料。结果 :肿瘤位于横结肠 2例 ,降结肠 1例 ,乙状结肠 1例 ,直肠 5例。主要临床表现为腹痛、消化道出血、腹部包块及大便不畅、肛门坠胀等。内镜和 X线钡剂检查为主要诊断手段。病理切片是确诊的关键。治疗以手术为首选。本组手术切除率为 78%。结论 :大肠平滑肌肉瘤多数位于直肠内。本组直肠平滑肌肉瘤占 5 6 %。一旦确诊 ,应行根治性的手术为宜。对复发及转移的病人 ,也应采取积极的态度。早期诊断及手术中的无瘤技术是预防复发、提高生存率的关键
Objective: To investigate the clinicopathological features and surgical treatment of large intestine leiomyosarcoma. Methods: The clinical data of 9 cases of large intestine leiomyosarcoma were collected and analyzed. Results: The tumor was located in 2 cases of transverse colon, 1 case of descending colon, 1 case of sigmoid colon and 5 cases of rectum. The main clinical manifestations of abdominal pain, gastrointestinal bleeding, abdominal mass and poor stool, anus bulge and so on. Endoscopic and X-ray sputum examinations are the main diagnostic tools. Pathological sections are the key to diagnosis. Treatment is the first choice for surgery. The surgical resection rate was 78% in this group. Conclusion: Most of the large intestine leiomyosarcomas are located in the rectum. The group of rectal leiomyosarcoma accounted for 56%. Once diagnosed, radical surgery should be appropriate. Patients with recurrence and metastasis should also adopt a positive attitude. Early diagnosis and operation of tumor-free techniques are key to prevent relapse and improve survival
