Comparison of Clinical Efficacy and Safety Between TROPIS Modified Suture Method and Traditional Incision Suture Method in the Treatment of High Position Anal Fistula
Objective To investigate the clinical effect of modified transanal opening of intersphincteric space(TROPIS)and traditional incision and thread hanging surgery in the treatment of high position anal fistula.Methods 72 patients with high position anal fistula admitted to our hospital from May 2021 to May 2023 were selected as the research objects,and were divided into a control group and an observation group according to random number table method,with 36 cases in each group.The control group was treated with traditional incision and thread hanging surgery and the observation group was treated with TROPIS modified suture method.The operation status,postoperative recovery,pain score,anal function and complications were compared between the two groups.Results The operation time and hospital stay of the observation group were(62.52±6.13)min and(8.52±1.13)d,respectively,which were shorter than those of the control group,and the intraoperative blood loss was(80.41±6.32)mL,which was lower than that of the control group,with statistical significance(P＜0.05).The time of hematochezia,pus shedding and wound healing in the observation group were(5.12±1.02)d,(4.08±0.46)d and(25.63±2.38)d,respectively,which were shorter than those in the control group,and the differences between groups were statistically significant(P＜0.05).On 1,3 and 7 adys after surgery,the Visual Analogue Scores of the observation group were(3.96±0.45)points,(2.81±0.38)points and(1.81±0.24)points,respectively,which were lower than those of the control group,and the differences between the groups were statistically significant(P＜0.05).3 months after surgery,the average duration of MUP of puborectum muscle and internal sphincter muscle in the observation group was(6.95±1.05)ms and(7.57±1.12)ms,respectively,which were both longer than those in the control group.Anal canal resting pressure and maximum systolic pressure were(45.11±4.15)mmHg(1 mmHg=0.133 kPa)and(176.52±11.33)mmHg,respectively,higher than those in the control group,and the differences between groups were statistically significant(P＜0.05).The incidence of complications in the observation group was lower than that in the control group,the difference was statistically significant(P＜0.05).Conclusion TROPIS is more effective in the treatment of high position anal fistula,which can reduce surgical trauma,reduce postoperative pain score,protect anal function and reduce complications.
