Abstract
Fistula-in-ano is a track lined by granulation tissue, which connects deeply with the anal canal or rectum and superficially with the skin of the perianal region. It usually results from an anorectal suppuration which burst spontaneously or was surgically drained inadequately.
The current treatment of anorectal fistulae is confronted with two complication (a) change in sphincter function and (b) recurrence.
This study included 30 patients suffering from low perianal fistula (22 males& 8 females), their age ranged between 19 -43 years old (mean 28.5 years)The patients had been divided into 2 groups; each group was formed of 15 patients. This study was carried out at General Surgery Department of Minufiya University Group (A), all fifteen patients who treated by traditional fistulotomy.
Group (B), all fifteen patients who underwent fistulotomy by electrocautery.
After statistical analysis of the results we found that A-Operative assessment 1-Time of operation It is found that the operative time is significantly shorter in group (B) shorter than group (A)2-Operative blood loss Significant less or no blood loss was observed in group (B) while more blood loss occur in group (A)Post-operative assessment 1-Post operative pain Significant lower pain perception and faster pain relieve is noted in group (B)2- Hospital stay Significant short hospital stay was recorded in group (B) of cautery procedure mean= 0.85 day meanwhile hospitalization needed for about 1-3 day of group (A) mean=1.5 day 3-Time of healing Time needed for healing in group (B) was 3-5 week mean=4.06 which is shorter than needed for healing in group (A) was 6-10 week mean=8.06 C-post-operative complication-Major complication
1-facel incontinence
No patient in both groups suffering from post operative incontinence to stool or flatus
2-Recurrence Recurrence occurred in two cases of group (A) due to wound infection with percentage of recurrence (13.3%) meanwhile no recurrence in group(B)with percentage of recurrence (0%)This study was done to evaluate the efficacy of treatment of low anal fistula by electrocautery over fistulotomy and the study showed that fistula cauterization is a simple and easy technique without complication and less expensive. It is performed as an outpatient procedure and the results are satisfactory to the patients and surgeons.
