Thirty-two patients who had anastomoses to the extraperitoneal rectum underwent radiographic contrast studies about two weeks after operation in order to determine the incidence of anastomotic dehiscence. No extravasation occurred in the sixteen anastomoses in which the middle hemorrhoidal arteries were intact, but partial disruption occurred in four of seventeen (24%) anastomoses in which the middle hemorrhoidal arteries were sacrificed. Since not all patients with anastomotic dehiscence after low anterior resection are symptomatic, the incidence of anastomotic breakdown will be under-estimated unless x-ray studies are performed. More data are required for a better understanding of the technical features of operation which will reduce the incidence of leakage from anastomoses to the extraperitoneal rectum.
32例行直肠腹膜外吻合术的患者在术后约两周接受了X线造影检查，以确定吻合口裂开的发生率。在16例痔中动脉完整的吻合口中未出现造影剂外渗，但在17例（24%）牺牲了痔中动脉的吻合口中，有4例出现了部分裂开。由于并非所有低位前切除术后吻合口裂开的患者都有症状，因此除非进行X线检查，否则吻合口破裂的发生率将被低估。需要更多的数据来更好地了解手术的技术特点，以降低直肠腹膜外吻合口漏的发生率。
