An acute fissure when observed by everting the anus *shows longitudinal muscle fibres in the floor of the ulcer. These are fibres of the conjoint longitudinal muscle layer which have passed downwards through the internal anal sphincter to gain attachment to the anal canal and perianal skin. If the lesion persists, the longitudinal fibres ulcerate through to expose the underlying whitish circula...

Anal pain is a common presentation in colorectal clinic. Accurate diagnosis often requires examination under anaesthesia as pain prevents careful assessment. This report intends to highlight a rare cause of a superficial perianal fistula caused by an ingested foreign body. A 36-year-old Afro-Caribbean gentleman underwent examination under anaesthesia of rectum. He had a 2-week history of perian...

A case in which an infiltrating mucinous carcinoma developed within a suprasphincteric fistula-in-ano is presented. The diagnosis was suspected on biopsy and confirmed by repeat biopsy. The clinical and histological features of this case establish with certainty that the carcinoma arose within the fistula and was not a secondary manifestation of the tumour. It is suggested that this rare compli...

Background: As a revolutionary sphincter-preserving approach, Wilhelm proposed "Fistula Laser Closure" (FiLaC) in 2016. It uses radial emitting laser probe and had an initial rate of success 81.8 percent 11 patients with median follow-up 7.4 months. Aim the study: To analyze Fistula Closure technique's efficacy treating high trans-sphincteric fistulas ano, look at procedure's effects on anal co...

The primary importance of magnetic resonance (MR) imaging in evaluating anal fistulas lies in its ability to demonstrate hidden areas of sepsis and secondary extensions in patients with fistula in ano. MR imaging is relatively expensive, so there are many healthcare systems worldwide where access to MR imaging remains restricted. Until recently, computed tomography (CT) has played a limited rol...

An ileal pouch fistula is an uncommon complication after an ileal pouch anal anastomosis. Most patients who suffer from an ileal pouch fistula will need surgical intervention. However, the surgery can be invasive and has a high risk compared to endoscopic treatment. The over-the-scope clip (OTSC) system was initially developed for hemostasis and leakage closure in the gastrointestinal tract dur...

Therefore, the fistulotomy is regarded as the standard treatment for simple anal fistulae and is the most widely-performed procedure. Although whether to perform a fistulotomy or a fistulectomy may be controversial, the fistulotomy is thought to be preferable because healing times are significantly shorter whereas recurrence rates are comparable. Compared with the fistulotomy, the fistulectomy ...
