OBJECTIVE
To generalize the clinical use of transsphincteric operation (Mason operation) for rectal lesions.
METHODS
Clinical data of 120 patients with middle and lower rectal lesions who underwent Mason operation from Aug. 1990 to Aug. 2005 were analyzed retrospectively.
RESULTS
There were 61 cases with villous adenoma including 26 with cancerization, 25 cases with rectal cancer including 16 cases with early rectal cancer, and 17 with submucosal tumor. Of the 103 patients with rectal tumor, 98 underwent partial rectectomy, 5 segmental rectectomy. The postoperative complications included incision infection in two cases (1.6%), fistula in 4 cases (3.3%). Three patients (3.0%) had postoperative local recurrence. 90.2% of the rectal cancer patients (46/51) survived more than five years after Mason operation.
CONCLUSION
Mason operation is satisfactory because of good exposure and simple access to the rectum, which is suitable for those lesions that could be locally resected on the mid and low rectum.
目的
总结经括约肌间手术（梅森手术）在直肠病变中的临床应用。
方法
回顾性分析1990年8月至2005年8月期间120例接受梅森手术的中低位直肠病变患者的临床资料。
结果
绒毛状腺瘤61例，其中癌变26例；直肠癌25例，其中早期直肠癌16例；黏膜下肿瘤17例。103例直肠肿瘤患者中，98例行直肠部分切除术，5例行直肠节段切除术。术后并发症包括切口感染2例（1.6%），肛瘘4例（3.3%）。3例（3.0%）术后局部复发。90.2%的直肠癌患者（46/51）在梅森手术后存活超过5年。
结论
梅森手术暴露良好，直肠显露简单，效果满意，适用于中低位直肠可局部切除的病变。
