Figure. 2. Surgical
findings of the transanal procedure
We entered the layer between the internal and external sphincters and
proceeded with the detachment of the pelvic muscles to the extent that
the prostate was palpable on the ventral side and the coccyx on the
dorsal side. After peeling to that depth, we spread three pieces of
gauze all around the deepest parts. They gauze contained a liquid
prepared by dissolving 25 mg of ICG in 10 mL of water containing sodium
arginine.
