局部切除术对早期低位直肠癌的临床疗效

Effectiveness of Local Excision for Early Low Rectal Cancer

目的探讨局部切除术治疗早期低位直肠癌指征并评估其疗效。方法回顾性分析42例经局部切除术治疗和病理证实的早期低位直肠癌患者临床资料。结果42例早期低位直肠癌均为局部肿瘤完整切除。无手术死亡者。无严重术后并发症。获随访39例（92．86％）。39例早期癌中36例（92．31％）术后生存〉5年，3例术后1．5～4年仍健在。总局部复发率为9．52％（4／42），复发距手术间隔期为1．5-2年；其中再次行Dixon术2例，改良Bacon术1例，局部扩大全层切除术1例。结论对经仔细选择的早期低位直肠癌局部切除术是1种安全而有效的治疗方法。

Objective To discuss the indication and to evaluate the effectiveness of local tumor excision for the treatment of early low rectal cancer. Methods The clinical data of 42 patients with early low rectal cancer resected by operation and confirmed by pathology were retrospectively analysed. Results 42 patients with early low rectal cancer were treated by local tumor excision for curative intern ,no patients died and no severe complication occured in this technique. 39（92.86% ） patients of whom were followed up carefully. Among them,36（92.31% ） patients existed for over 5 years and 3 patients remain alive at 1.5-4 years after operation. 4 （9.52%） patients developed local recurrences at 1.5-2 years after operation,in 42 patients. Dixon＇s operation was again performed in 2 cases,modified Bacon＇s operation in 1 case,local excision once again in 1 case. Conclusion Local tumor excision is a safe and e：ffeetive preeedure for the treatment of carefully selected early low rectal cancer.
