When additional ischioanal
fossa abscess or secondary tract is present, they are accepted as grade 4 fistula (Fig.
Results: Fifty (89%) patients received preoperative chemoradiotherapy: 51 (91%) patients were treated with the sacrococcyx preserved; 27 (48%) patients with the levator ani muscle partially preserved bilaterally; 20 (36%) patients with the levator ani muscle partially preserved unilaterally and the muscle on the opposite side totally preserved; 7 (13%) patients with intact levator ani muscle and part of the ischioanal
fat bilaterally dissected; and 2 (4%) patients with part of the ischioanal
fat and intact lavator ani muscle dissected unilaterally and the muscle on the opposite side partially preserved.
The location is most commonly perianal or ischioanal
. If that's not the suppuration site, the abscess is intersphincteric or supralevator, in which case a confirmatory CT scan is called for before proceeding with treatment.
We performed combined anal sphincteroplasty and counterclockwise rotation manner gracilis muscle transposition procedure by transperineal access to provide the ischioanal
fossa access in a male patient suffered from complet fecal incontinence (FI) for one year following low anterior rectal resection operation.
It passes through the greater sciatic foramen along the posterior aspect of the ischial spine close to the sacrospinous ligament and enters the ischioanal
fossa through the lesser sciatic foramen.
This is a 28-year-old nulliparous patient with a past medical history of polycystic ovarian syndrome (PCOS), anxiety, and depression with newly diagnosed endometrioid adenocarcinoma in her right ischioanal
There is no branching within the sphincteric complex or extension into the ischioanal
They also do not have the legs or the arms that are placed using trocars through the transobturator or ischioanal
fossae, which can approach nearby nerves, arteries, or other vital structures.
The anal triangle contains the anal canal, ischioanal
fossa, and the pudendal canal.
The CT also revealed a collection of smaller contiguous cysts in the left ischioanal
fossa and the left perineal subcutaneous fat.
abscess was correctly diagnosed in one patient.
After subdermal infiltration at two sites anterior and posterior of the anal ring, the anococcygeal ligament is deeply infiltrated with 5 ml; 8 - 10 ml are injected into both ischioanal
spaces while withdrawing the needle to anaesthetise the deep nerve endings.
