Hypothesis: Commercially produced fibrin sealant can be used to completely
close both simple and complex fistulae in ano.
Methods: A 29-patient prospective nonrandomized clinical trial was performe
d. In the operating room, the patient underwent an er;amination with anesth
esia and the primary and secondary fistula tract openings were attempted to
be identified. The fistula tract was curetted and fibrin sealant was injec
ted into the secondary fistula tract opening until fibrin sealant was seen
coming from the primary opening. A petroleum jelly gauze was then applied o
ver the secondary opening and the patient was sent home. Follow-up visits w
ere scheduled for 1 week, 1 month, 3 months, and 1 year later.
Results: Twenty-nine consecutive patients received fibrin sealant injection
s for their fistulae in ano, with a mean follow-up of 6 months. Two patient
s had a history of Crohn disease (regional enteritis) and 2 patients had hu
man immunodeficiency virus infection. Overall, 17 (68%) of 25 patients have
had successful closure of their fistula with 4 patients lost to follow-up.
Two patients required reinjection with fibrin sealant, and neither of thes
e subsequently had closure. One of the 2 patients with Crohn disease had cl
osure, as well as I human immunodeficiency virus-positive patient. In addit
ion, there has been no evidence of incontinence or complications related to
the use of fibrin sealant in this procedure.
Conclusions: Initial results in the treatment of chronic anorectal fistulae
using commercial fibrin sealant are optimistic, but require further suppor
t through longer follow-up data. Fibrin sealant treatment of anorectal fist
ulae offers a unique mode of management which is safe, simple, and easy for
the surgeon to perform. By using fibrin sealant, the patient avoids the ri
sk of fecal incontinence and the discomfort of prolonged wound healing that
may be associated with fistulotomy.
