尽管直肠间质瘤仅占胃肠道间质瘤(GIST)的4.2％,但是直肠的特殊解剖位置和其同周围器官复杂的毗邻关系以及术中可能涉及是否需要保留肛门等问题,使直肠间质瘤的外科治疗具有一定的难度和挑战.由于直肠间质瘤所特有的生物学特性,在多数情况下可行局部切除.然而,当下有多种手术入路和手术方法可行直肠间质瘤的局部切除,究竟哪种手术更适合目前尚无定论.本文回顾性分析2003年3月至2012年9月北京协和医院采用后入路经肛门括约肌直肠肿瘤切除术(Mason术)治疗18例直肠间质瘤患者的临床资料.结果表明:该手术治疗直肠间质瘤不仅符合肿瘤学原则,而且可在最大程度上保留肛门和减轻手术创伤,是目前手术治疗直肠间质瘤较为理想的术式之一.

In spite of the fact that rectal stromal tumor accounts for only 4.2％ of the gastrointestinal stromal tumor,its surgical treatment is still very difficult and challenging due to the special anatomical position of rectum,its complicated anatomical relationship with adjacent organs,and whether the anus be preserved.Local resection of rectal stromal tumor is feasible and reasonable owing to its biological characteristics.However,there are many approaches and methods for local resection and no consensus has been reached.The clinical data of 18 patients with rectal stromal tumor who were treated by local resection via transposterior approach at the Peking Union Hospital from March 2003 to September 2012 were retrospectively analyzed.The surgery not only applies with the oncology treatment principle,but also preserves anus and limits the surgical injury to a large extent.Therefore,it is one of the most ideal surgical methods for the treatment of rectal stromal tumor.
