Postoperative Outcome of Fistulotomy with Marsupialization in the Surgical Management of Simple Anal Fistula...

Assess the wound healing time and early post-operative outcome of fistulotomy with marsupialization, as a surgical treatment of simple fistula-in-ano. This interventional study was performed at the Department of Colorectal Surgery, Bangabandhu Sheikh Mujib Medical University, Bangladesh from July 2017 to June 2018. Total 30 cases of simple anal fistula were selected according to inclusion criteria. Patients were non-randomly divided in two groups. Fifteen (15) cases were undergone a fistulotomy-lay open (control group) and another 15 cases undergone a fistulotomy with marsupialization (experimental group). The result was tested by t-test, chi-square test. Statistical significance was set at p<0.05. The mean age of the study population was 42.07±13.69 years in fistulotomy-lay open group and 46.00±12.99 years in fistulotomy with marsupialization group. In both group, number of male was higher. Perianal discharge and induration or swelling at perianal skin was most common findings. Mean healing time was earlier in fistulotomy with marsupialization group (16.60±11.15 days) than lay open group (27.07±14.28 days) due to marsupialization technique, the matter of fact that the deep, unepithelized wound has become smaller. No significant difference of postoperative pain, bleeding, wound infection and fecal incontinence in both group. The study shows marsupialization of the wound after fistulotomy for simple fistula in ano results in significantly faster healing in comparison with lay open-fistulotomy, less bleeding without increasing postoperative pain and the infections.
