Nowadays most Authors agree that preserving the rectum is useless, so it is sectioned at the level of anorectal junction. The preparation of the rectum toward anorectal junction is usually intramesorectal, which rises the risk of bleeding but also reduces the risk of nerve lesions. However mesorectal excision is mandatory in case of either severe dysplasia or cancer. After pouch construction, ileopouch-anal anastomosis can be either manual or stapled.

The ears therefore pertain to the kidney and kidney also control anterior and posterior orifices.

Unfortunately not much more was published about prostate aspiration biopsies for the next 20 years. Then in 1960 Parry and Finelli described a modified method which was highly successful in allowing a directed biopsy through the perineum (Parry and Finelli, 1960). Their technique afforded greater needle control by using digital-guidance.

In 1930 Ferguson modified the technique and published his series of 280 patients who had prostate needle aspiration biopsy using an 18-gauge needle via the transperineal approach and was able to remove adequate tissue in 78 to 86% of his cases (Ferguson, 1930) (figure 6). The patient was placed in the lithotomy position and local anaesthetic was infiltrated just lateral to the median raphe 1cm anterior to the anus. The index finger of the left hand was introduced into the rectum guiding an 18 gauge needle introduced into the perineum taking care to avoid the rectum and urethra....

The procedure described by Young involved a transverse incision between the ischial tuberosities 2 cm above the anus (Young, 1926). The ischiorectal fossa was then opened by blunt finger dissection, carrying the dissection medially and reflecting the rectum posteriorly. The central tendon of the perineum was then cut exposing the recto-urethralis muscle which was opened by sharp dissection and reflected laterally, exposing the capsule of the prostate (figure 5). The abnormal area on the prostate was grasped with Allis forceps and excised widely and deeply.

Cancers of the Anus Cancers of the anus account for 1–2% of the malignant tumors of the large bowel. Most such lesions arise in the anal canal, the anatomic area extending from the anorectal ring to a zone approximately halfway between the pectinate (or dentate) line and the anal verge. Carcinomas arising proximal to the pectinate line (i.e., in the transitional zone between the glandular mucosa of the rectum and the squamous epithelium of the distal anus) are known as basaloid, cuboidal, or cloacogenic tumors; about one-third of anal cancers have this histologic pattern.
