Anal Fistulotomy with Radiofrequency: a Better
Option to a Conventional Procedure
Gupta Nursing Home, Nagpur,
Even after the availability of many different surgical options,
most surgeons still prefer the classical lay open technique
(fistulotomy) as the gold standard for the treatment of anal
fistula. This study analyzes the procedure and outcome of radiofrequency
fistulotomy over the conventional scalpel method.
Material and methods.
Fifty patients with low fistula in ano were analyzed in a prospective
study. They were randomized into conventional and radiofrequency
fistulotomy groups. Parameters measured included time taken
for the procedure, amount of blood loss, postoperative pain,
period taken for return to work and recurrence rate. The patients
were followed over a period of 30 months.
The average time for complete wound healing was 49 days. The
patients took a mean period of 7 days to return to their routine.
In 7 patients the wounds took more than 80 days to heal and
were labeled as delay in wound healing. Two patients developed
a recurrence. The comparative study between conventional and
radiofrequency fistulotomy showed that procedure time was shorter
(p= 0.001); intra operative bleeding was much less (p=0.0004),
return to work was earlier (p= 0.029) and wound-healing time
was shorter (p=0.0017) in radiofrequency procedure.
In terms of parameters set for the study, the radiofrequency
technique was found to have significant advantages over conventional
fistulotomy procedure with regard to operation time, blood loss,
return to normal activity and healing of the wounds.
