A fistula brush and forceps for cleaning the tract and clearing any granulation tissue. The VAAFT procedure is done in two phases, diagnostic and operative. Before the procedure, the patient is given a spinal or general anaesthetic and is placed in the lithotomy position (legs in stirrups with the perineum at the edge of the table).
Goodsall's rule relates the external opening (in the perianal skin) of an anal fistula to its internal opening (in the anal canal). It states that if the perianal skin opening is posterior to the transverse anal line, the fistulous tract will open into the anal canal in the midline posteriorly, sometimes taking a curvilinear course.

There are several forms of imperforate anus and anorectal malformations. The new classification is in relation of the type of associated fistula. [7] The Wingspread classification was in low and high anomalies: [citation needed] A low lesion, in which the colon remains close to the skin.
A rectal prolapse occurs when walls of the rectum have prolapsed to such a degree that they protrude out of the anus and are visible outside the body. [2] However, most researchers agree that there are 3 to 5 different types of rectal prolapse, depending on whether the prolapsed section is visible externally, and whether the full or only partial thickness of the rectal wall is involved.
The diagnosis can be made clinically with tests like ultrasound, X-rays, voiding cystourethrogram (VCUG) and cloacagram. MRI of the spine and pelvis and endoscopic examinations may also be performed. [6] Failure to identify a cloaca as being present in a newborn may be dangerous, as more than 90% have associated urological problems.
Dynamic pelvic MRI, also called MRI defecography is an alternative that is better for some problems but not as good for other problems. [38] Proctosigmoidoscopy involves the insertion of an endoscope (a long, thin, flexible tube with a camera) into the anal canal, rectum and sigmoid colon. The procedure allows for visualization of the interior ...
