Anal Canal - Simplified Anatomy
Anal dysplasia is a condition in which some of the cells within the anus have transformed into abnormal cells. High resolution imaging is needed to detect these abnormal lesions. Anal dysplasia is not cancer, but it is a pre-cancerous condition. In other words, if the abnormal cells are left untreated, they can turn into cancerous tumors. Anal dysplasia is not always accompanied by symptoms.
A colposcope, a tool that provides magnified images. The colposcope provides a clear picture of the anal canal, allowing the doctor to see any abnormal cells.

Anal dysplasia is diagnosed with the use of two tests: an anal pap, and High Resolution Anoscopy, or HRA. In an anal pap, a swab is used to collect some cells from the anus. These cells are then examined under a microscope to determine if any of them are abnormal. HSIL is an acronym for high grade squamous intraepithelial lesion, and LSIL means low grade squamous intraepithelial lesion. A lesion is an area of abnormal tissue, and high grade versus low grade refers to the likelihood that it will progress to cancer. HSIL may also be referred to as anal dysplasia.
If any lesions are discovered, a biopsy can be performed during the HRA procedure. A biopsy is the only way to make an actual diagnosis of anal dysplasia.
Pain after a biopsy is minimal, and most patients only require over the counter medications like Tylenol or Advil for pain relief. If a biopsy is performed, the cells will be examined by a pathologist to determine if they represent a low-grade or high-grade lesion. Cancerous cells may also be identified.
Anal squamous intraepithelial lesions (ASIL) represent a spectrum of disease that spans from mild squamous dysplasia to severe squamous dysplasia, the putative precursor to invasive squamous cell carcinoma. 1 Although the management of mild dysplasia, known as condylomatous disease when grossly visible, and invasive disease are relatively straightforward, the management of severe Cited by: Jasmine Lynn is a huge fan of high heels and she is also an anal whore Tags: anal, beauty, blonde, cute, hardcore, high heels, jasmine lynn 38 days ago. High in the anal canal, the mucosa forms four to six longitudinal folds. Figure The main anatomic components of the rectum and anus. The smooth muscle of the internal anal sphincter (IAS) is continuous with the inner circular muscle of the rectum. It becomes more prominent low in the anal canal.
Low-grade lesions only need to be periodically monitored, whereas high-grade lesions will require further treatment. IRC is performed during an office visit.

It is nearly painless and causes minimal bleeding. Local anesthetics are used to keep you comfortable during the procedure. No suppositories or enemas are required ahead of time.
For many patients, two or three treatments will be needed to ensure that all abnormal cells have been destroyed. The anal canal is located within the anal triangle of the perineum between the right and left ischioanal fossae.
It is the final segment of the gastrointestinal tract, around 4cm in length. The canal begins as a continuation of the rectumand passes inferoposteriorly to terminate at the anus.
Except during defecation, the anal canal is collapsed by the internal and external anal sphincters to prevent the passage of faecal material. It is formed by the fusion of the internal anal sphincter, external anal sphincter and puborectalis muscle, and is palpable on digital rectal examination.
High anal canal
Above the anal valves are small pouches which are referred to as anal sinuses - these contain glands that secrete mucus. This is a result of their different embryological origins:.
Coccyx and sacrum. Bulb of the penis.
As discussed above, the pectinate line divides the anal canal into two parts - which have a different arterial supply, venous drainage, innervation and lymphatic drainage. Pathological haemorrhoids are observed in people who suffer from constipationprolonged straining when defecating, or raised intra-abdominal pressure e. They can cause bleeding and itchiness, and depending on the severity, can be managed conservatively or surgically.

Anastomosing branches from the middle rectal artery. Inferior rectal artery branch of the internal pudendal artery.
Nerve Supply Visceral innervation via the inferior hypogastric plexus. Somatic innervation via the inferior anal nerves branches of the pudendal nerve. Sensitive to pain, temperature, touch and pressure.
The anal canal is the final segment of the gastrointestinal tract. It has an important role in defecation and maintaining faecal continence. In this article, we shall look at the anatomy of the anal canal - its position, structure, relations and neurovascular supply/5.
