Abstract
Fistula-in-ano is one of the most common benign anal conditions in daily surgical practice.
The cryptoglandular hypothesis states that infection of the anal glands is the primary cause of anal fistula.
The present study aims at comparing the efficacy of open fistulotomy and ligation of intersphincteric fistula tract (LIFT) procedure based on its post-operative outcomes. The Present study included 30 patients presented with low transsphincteric perianal fistula 27 (90%) males and 3(10%) females divided into two groups each group consists of 15 patients. group I patients subjected to inter sphinectric ligation of perianal fistula (LIFT) procedure, group II patients subjected to conventional fistulotomy.
Operative time in our study was significantly higher in group (I) managed by LIFT with mean operative time 32.53 minutes than group (II) manged by fistulotomy with mean operative time 20.87 mins.
Wound healing was faster in group (I) manged by LIFT with mean time of wound healing (4.53) weeks than group (II) manged by fistulotomy with mean time of wound healing (5.67) weeks.
Post-operative pain perception and need for analgesics was more in group (II) managed by fistulotomy, than group (I) managed by LIFT. As the Mean Visual Analogue Scale (VAS) was significantly higher in group II (5.7) compared to group I (3.3).
Post-operative wound infection occurred in 2 Patients in group (I) manged by LIFT and in 2 patients in group (II) manged by fistulotomy.
Summary
80
Urine retention occurred in 2 Patients in group (I) manged by LIFT and in 2 patients in group (II) manged by fistulotomy.
There were no cases of incontinence after performing the LIFT technique in all our patients in group I.
There were 2 cases of incontenance to gases only after fistulotomy in group II with score 4/20 by (WIS).
Healing rate after LIFT was 80% (12/15 patients) with recurrence of 20% (3/15 patients).
Healing rate after fistulotomy was 93.3% (14/15 patients) with recurrence 6.7% (1/15 patients). Conventional fistulotomy is commonly used procedure and still relied on by the majority of surgeons as the gold standard for treatment of peri anal fistula. It can cure the fistula but this may involve prolonged wound healing, anal deformity and compromise of anal continence.
LIFT procedure is effective and sphincter saving technique for fistula in ano with shorter healing time and lower incidence of postoperative anal incontinence, as compared to open fistulotomy.
