With MRI providing excellent anatomical details and relations of fistulous
tracts and their associated abscesses, an MR-based classification is now used that categorises perianal fistulas into five grades.
tract is marked by placing a 14-F Foley catheter.
In pythiosis lesions, dead cells behave as a foreign body, triggering an inflammatory response of the body in order to promote phagocytosis and allow for the subsequent repair of the tissue affected, so in the repair and healing process there are necrotic masses and calcifications of a white-yellowish color containing hyphae and eosinophil infiltrates, which dimensions vary from 2 to 10 mm in diameter, called "kunkers", which, together with the presence of fistulous
trajectories and fibrinosanguinolent discharges, are unequivocal signs of pythiosis (3).
A linear incision was made on skin extending the commisures of wound and fistulous
tract was identified.
Fourth branchial fistulous
tracts originate from the piriform sinus and descend to exit the pharynx deep to the superior laryngeal nerve.
His 1978 article on The final evaluation and classification of the surgical treatment of the primary anorectal cryptoglandular intermuscular (intersphincteric) fistulous
abscess and fistula (11) was a culmination of his understanding and treatment of the condition.
The presacral mass can erode into the rectum leading to neuroenteric fistulous
communication resulting in fatal meningitis and large pneumocephalus.
Forming of fibroses and fistulous

Migration of the gossypiboma may occur externally (extrusion) through a fistulous
tract or internally, when it is adjacent to a hollow viscus (rectum, vagina, bladder, or intestinal lumen) (10).

opening in the upper part of the anal canal with a bubbling mixture of methylene blue and hydrogen peroxide.
Ultrasonographic detection of fistulous
tracts and foreign objects in muscles of horses.
Stricture, proctitis, fistulous
connections, diminished rectal compliance, decreasing storage capacity with resultant small bowel movements and perforations are late complications of injury that are usually clinically manifested within 3-4 years after RT.
