Abstract

Objective: To investigate the effectiveness of endorectal advancement flaps for middle and low rectovaginal fistulas.

Methods: A retrospective cohort of 57 patients who underwent surgery via an endorectal advancement flap in the RVF between July 2007 and March 2022 was generated. The clinical features of the patients were reviewed. The associations between fistula closure and diverse clinical parameters, including age, body mass index, diameter of the fistula, prior repair, pathological type, diverting stoma and operative method, were analyzed.

Results: Congenital (n = 19, 33.33%) and obstetric (n = 19, 33.33%) injuries were the most common etiologies of rectovaginal fistulas. The success rate in patients who underwent a first repair was 66.7%, and the overall success rate was 70.2% after repetition of the same technique. There were no significant differences in the closure rate between the success and failure groups in age, body mass index, prior repair, preoperative colostomy, or pathological type (p > 0.05). However, a diameter greater than 1 cm predicted a lower success rate for both the first repair (p < 0.05) and the overall procedure (p < 0.05). Two cases of failure with a diameter greater than 1 cm succeeded after a sphincter repair procedure half a year later.

Conclusion: The endorectal advancement flap is safe and effective for removing simple rectovaginal fistulas at the middle and lower positions. A diameter greater than 1 cm is an independent risk factor for this surgical technique, and sphincteroplasty may be a better choice for this condition.

直肠内推进皮瓣治疗单纯性直肠阴道瘘的单中心回顾性分析。
目的:探讨直肠内推进皮瓣治疗中、低位直肠阴道瘘的疗效。方法:对2007年7月至2022年3月间接受裂谷热直肠内推进皮瓣手术的57例患者进行回顾性队列研究。回顾了患者的临床特点。分析瘘口闭合与年龄、体重指数、瘘口直径、既往修复、病理类型、转移造口及手术方式等临床参数的关系。结果:先天性损伤(n = 19, 33.33%)和产科损伤(n = 19, 33.33%)是直肠阴道瘘最常见的病因。首次修复患者的成功率为66.7%,重复相同技术后的总成功率为70.2%。成功组和失败组在年龄、体重指数、既往修复、术前结肠造口、病理类型等方面的结缔组织率差异无统计学意义(p < 0.05)。结论:直肠内推进皮瓣用于单纯性直肠阴道瘘中、下位的切除是安全有效的。括约肌直径大于1cm是这种手术技术的独立危险因素,括约肌成形术可能是这种情况下更好的选择。
