This study was designed to detect factors that predict the occurrence of continence disorders after anal fistulotomy.
A retrospective study of the charts of 312 patients was undertaken. A questionnaire was sent to all patients, with a response rate of 90 percent.
Minor continence disorders occurred in 73 patients, incontinence did not occur. Multivariate analysis (chi-squared test) was performed showing that extensions (P = 0.008), location (P = 0.03), and level (P = 0.029) of the anal opening appeared to be independent factors.
Patients with high openings, posterior openings, or fistula extensions are at risk to develop continence disorders after anal fistulotomy.
本研究旨在检测预测肛瘘切开术后控便障碍发生的因素。
对312例患者的病历进行回顾性研究。向所有患者发放问卷，回复率为90%。
73例患者出现轻度控便障碍，未发生失禁。进行多因素分析（卡方检验）显示，肛管开口的延伸（P = 0.008）、位置（P = 0.03）和水平（P = 0.029）似乎是独立因素。
高位开口、后位开口或肛瘘延伸的患者在肛瘘切开术后有发生控便障碍的风险。
