Tunnel Cross-sectional Diameter (hung) Counterpart Floating Line Drainage For Treatment Of Clinical Research, High Heels Iron Anal Fistula

Objective:To observe and assess the therapeutic effect of the modus operandi with intercept the trail,tie the muscle and with a floating-rubber tissue in the tunnel for contra-aperture drainageing and the forte or the shortage of it in the treatment of posterior horseshoe anal fistula of superior position.Methods:The 40 cases of posterior horseshoe anal fistula of superior position were randomly divided into trials group and controlled group,20 cases in trials group received the modus operandi with intercept the trail,tie the muscle and with a floating-rubber tissue in the tunnel for contra-aperture drainageing,20 cases in controlled group received the modus operandi with arc incisions sutured.To observe the curative effect,the operability of operative procedure,the afterreaction and complication of operative procedure,the status of wound healing and the anal disfunction and the relapse rate in six months.The relative results were calculated statistically with SPSS13.0 software.Statistical standard was accepted as the "α" value equal 0.05 for double tailed test.Results:The trials group surpass the controlled group in the aspects of the time of the operation,the volume of blood loss in operation and in the postoperative pain in the following three days after the first day of operation,The hydropsia of incisal opening(P＜0.05),The controlled group surpass the trials group in the aspects of the time of the healing(P＜0.05),There was no difference between the two groups in the postoperative pain in the first day,the retention of urine,the secondary infection,the anal disfunction,the curative effect and the relapse rate in six months(P＞0.05).And in the whole,scored with weighting,there was no difference between the two groups(P＞0.05).Conclusion:The modus operandi with intercept the trail,tie the muscle and with a floating-rubber tissue in the tunnel for contra-aperture drainageing could not only protect the anal function and give anal fistula a radical cure but also have evident technical dominance,such as the advangtage in manipuility,the smaller lesions in operation,and so on,Furthermore it effectively prevent the postoperative complications.In all,the modus operandi with intercept the trail,tie the muscle and with a floating-rubber tissue in the tunnel for contra-aperture drainageing should be a superordinary technique in in the treatment of posterior horseshoe anal fistula of superior position.
