Tunnel fistulectomy with multiseton drainage in treatment of complicated anal fistula / 中华全科医师杂志

ABSTRACT

Seventy seven patients with complicated anal fistula were randomly assigned to receive tunnel fistulectomy with multiseton drainage (group A, n=38) or traditional fistulectomy (group B, n=39) for treatment.The clinical data and the treatment outcomes of two groups were compared.There was no significant difference in operation time between two groups (P>0.05). However, group A was significantly superior to group B in postoperative pain Numerical Pain Rating Scak (NPRS) score [(2.2±0.84) vs. (4.2±1.3), P<0.05)], wound surface area [(3.7±0.84) cm2 vs. (7.28±1.83) cm2, P<0.05], wound healing time [(23.4±2.41) d vs. (38.8±3.49) d, P<0.05 ], cure rate(97.4% vs. 79.5%, P<0.05) and recurrent rate 1 year after surgery(5.3% vs. 25.6%, P<0.05). The postoperative anorectal dynamic parameters of group A were also better than those of group B (P<0.05). Compared to traditional fistulectomy, the tunnel fistulectomy with multiseton drainage has advantages of less pain, faster recovery, less disturbance in anal function and better long-term clinical effect in treatment of complicated anal fistula.
