Additional ligation of the intersphincteric fistula tract did not improve the outcome after endorectal advancement flap. [15] Fistula clip closure (OTSC Proctology) is a recent surgical development, which involves the closure of the internal fistula opening with a superelastic clip made of nitinol (OTSC). During surgery, the fistula tract is ...
The perianal injection route (intersphincteric or transsphincteric) gives better results than the transanal route according to one review. [3] Submucosal implant location may have a higher risk of erosion and sepsis. [10]
In 1993 Matos et al. described a technique of total anal sphincter preservation in high fistula in ano, which is based on the concept of excision of intersphincteric anal gland infection through the intersphincteric approach. [3] This novel technique was also documented in Corman’s textbook of colon and rectal surgery. [4]
Anorectal abscess (also known as an anal/rectal abscess or perianal/perirectal abscess) is an abscess adjacent to the anus. [1] Most cases of perianal abscesses are sporadic, though there are certain situations which elevate the risk for developing the disease, such as diabetes mellitus, Crohn's disease, chronic corticosteroid treatment and others.
An anal sac adenocarcinoma is an uncommon and aggressive malignant tumor found in dogs that arises from the apocrine glandular tissue of anal sac. The disease exists in cats as well, but is much less common in that species. [1] They are the second most common cancerous cause of hypercalcaemia (high serum calcium) in dogs, following T-cell ...
Low anterior resection syndrome is a complication of lower anterior resection, a type of surgery performed to remove the rectum, typically for rectal cancer.It is characterized by changes to bowel function that affect quality of life, and includes symptoms such as fecal incontinence, incomplete defecation or the sensation of incomplete defecation (rectal tenesmus), changes in stool frequency ...
Dogs and cats primarily use their anal gland secretions to mark their territory, and generally will secrete small amounts of fluid every time they defecate. Many will often express these glands when anxious or frightened as well. Dogs who are healthy can usually have a wide variety in the appearance of their sac's content. [14]
A rectovestibular fistula, also referred to simply as a vestibular fistula, is an anorectal congenital disorder where an abnormal connection exists between the rectum and the vulval vestibule of the female genitalia. If the fistula occurs within the hymen, it is known as a rectovaginal fistula, a much rarer condition. [1]
