Parks' modified technique for treatment of upper and medium transphincteral fistula
Keywords:
fistula, rectumAbstract
The aim of Parks' technique is the preservation of ali
the externa! sphincter. Crypt resection with a section
of the interna! sphincter prevents relapses and the seton
placed in the traject ensures drainage. In spite of
this, in 20% of the cases, delayed sphincter section is
necessary because of trajee! persistence. In a series of
cases authors used Parks' technique but instead of placing
Seton, the externa! muscular orifice was closed
from the a·nal canal with Dexon 4-0 stitches. Results
were optimum from the point of view of trajects' primary
healing (1-2 weeks), rather slower for the interna!
defect (3-5 weeks) with no subsequent incontinence sequel.
No relapses were found in follow-ups of 4 months
up to 5 years.
