目的:探讨应用弧形切割缝合器在治疗低位直肠癌(距肛缘3～7 cm)中的保肛效应。方法:14例低位直肠癌患者,遵循全直肠系膜切除治疗原则,应用弧形切割缝合器行保肛手术。随访6个月,观察其根治性、术后排便功能、手术并发症及局部复发率情况。结果:本组无手术死亡,术后病理学检查无切端癌残留,无大便失禁,无吻合口漏发生,吻合口狭窄1例,发生率为7.1%(1/14),局部无复发,患者术后肛门功能恢复较满意。结论:保肛手术可获得较好的手术根治与保肛门功能的效应。在狭窄骨盆中应用弧形切割缝合器保肛治疗安全、有效。
Objective: To investigate the anal sphincter effect in the treatment of low rectal cancer (3 ~ 7 cm from the anal verge) by arc cutting stapler. Methods: Fourteen patients with low rectal cancer followed the principle of total mesorectal excision. An arc-shaped incision suture was used for anal sphincter preservation. Followed up for 6 months, observed its radical, postoperative defecation function, surgical complications and local recurrence rate. Results: There was no surgical death in this group. There was no residual incision, no incontinence, no anastomotic leakage and anastomotic stenosis in 1 patient. The incidence was 7.1% (1/14) Postoperative anal function is more satisfactory. Conclusion: Anal sphincter preserving surgery can obtain good effect of operation cure and anal anus function. In the narrow pelvic arc cutting stapler anal suture security, effective.
