高位肛瘘弹力挂线局部压强测算的设计和应用

The Tension and Partial Pressure Mearsurement of Elastic Seton Treating High Anal Fistula

目的:通过对高位单纯性肛瘘弹力挂线的拉力及对局部组织压强的测定,探讨弹力挂线数值量化的可行性及临床意义,使挂线疗法的经验转化为规范化操作,提高临床疗效,防止和减少术后肛门失禁的发生。方法:测量60例高位肛瘘弹力挂线橡皮筋的拉力和对局部组织的压强,初步估算不同弹力挂线的临床疗效,并收集每例患者挂线脱落时间和术中橡皮筋的拉力及对组织产生的压强。结果:60例高位单纯性肛瘘患者治愈率为96.67%。6例患者术后第8~13天橡皮筋脱落,平均橡皮筋拉力为8.2±1.59N,挂线局部压强886.2±471.7KPa;37例患者术后第12~17天橡皮筋脱落,平均橡皮筋拉力为6.3±0.37N,挂线局部压强576.1±314.8KPa;15例患者术后第18-22天橡皮筋脱落,平均橡皮筋拉力为4.5±0.42N,挂线局部压强289.3±147.6 KPa。结论:肛瘘挂线拉力和弹力的测定科学可行,可作为量化肛瘘挂线的合理依据。

Objective ： To explore the feasibility and clinical significance of quantifying seton elastic force by means of measuring and re-stricting the seton elastic force and partial pressure during the procedure of treating high anal fistula, and transform the seton experience to normalized operation. Methods：The seton elastic force and partial pressure of 60 cases of high simple anal fistula were measured, and the clinical efficacy was estimated Preliminary. The data of seton elastic force and partial pressure was collected. Results：The clinical curative ratioof 60 cases of simple high anal fistula was 95%. The rubber bands of 6 cases fell offafter 8 - 13days of seton operation, with average elastic force of 8.2 ± 1.59N and partial pressure of 886.2 ±471.7KPa; The rubber bands of 37 cases fell off after 14 - 17days of seton operation, with average elastic force of 6.3 ±0. 37N and partial pressure of 576. 1 ±314, 8KPa; The rubber bands of 15 cases fell off after 18 -22 days of seton operation, with average elastic force of 4. 5 ± 0 .42N and partial pressure of 289. 3 ± 147. 6KPa. Conclusion ： The Tension and Partial Pressure Mearsurement of Elastic Seton Treating High Anal Fistula is feasible and it is a practice significance, and it can Provide a reference for quantifing the seton of high fistula.
