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. 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.
Colorectal surgery is a field in medicine dealing with disorders of the rectum, anus, and colon. The field is also known as proctology, but this term is now used infrequently within medicine and is most often employed to identify practices relating to the anus and rectum in particular. The word proctology is derived from the Greek words πρωκτός proktos, meaning "anus" or "hindparts", and -λογία -logia, meaning "science" or "study".
Ileostomy is a stoma constructed by bringing the end or loop of small intestine out onto the surface of the skin, or the surgical procedure which creates this opening. Intestinal waste passes out of the ileostomy and is collected in an external ostomy system which is placed next to the opening. Ileostomies are usually sited above the groin on the right hand side of the abdomen.
In medicine, the ileal pouch–anal anastomosis (IPAA), also known as restorative proctocolectomy (RPC), ileal-anal reservoir (IAR), an ileo-anal pouch, ileal-anal pullthrough, or sometimes referred to as a J-pouch, S-pouch, W-pouch, or a pelvic pouch, is an anastomosis of a reservoir pouch made from ileum to the anus, bypassing the former site of the colon in cases where the colon and rectum have been removed. The pouch retains and restores functionality of the anus, with stools passed under voluntary control of the person, preventing fecal incontinence and serving as an alternative to a total proctocolectomy with ileostomy.
Proctocolectomy is the surgical removal of the entire colon and rectum from the human body, leaving the patients small intestine disconnected from their anus. It is a major surgery that is performed by colorectal surgeons, however some portions of the surgery, specifically the colectomy may be performed by general surgeons. It was first performed in 1978 and since that time, medical advancements have led to the surgery being less invasive with great improvements in patient outcomes. The procedure is most commonly indicated for severe forms of inflammatory bowel disease such as ulcerative colitis and Crohn's disease. It is also the treatment of choice for patients with familial adenomatous polyposis.
A lower anterior resection, formally known as anterior resection of the rectum and colon and anterior excision of the rectum or simply anterior resection, is a common surgery for rectal cancer and occasionally is performed to remove a diseased or ruptured portion of the intestine in cases of diverticulitis. It is commonly abbreviated as LAR.
The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) is a 501c6 non-profit professional organization providing education on gastrointestinal minimally invasive surgery. It describes itself thus: The mission of the Society of American Gastrointestinal and Endoscopic Surgeons is to innovate, educate and collaborate to improve patient care.
Obstructed defecation syndrome is a major cause of functional constipation, of which it is considered a subtype. It is characterized by difficult and/or incomplete emptying of the rectum with or without an actual reduction in the number of bowel movements per week. Normal definitions of functional constipation include infrequent bowel movements and hard stools. In contrast, ODS may occur with frequent bowel movements and even with soft stools, and the colonic transit time may be normal, but delayed in the rectum and sigmoid colon.
Nigro protocol is the preoperative use of chemotherapy with 5-fluorouracil and mitomycin and medical radiation for squamous cell carcinomas of the anal canal. Success of the preoperative regimen changed the paradigm of anal cancer treatment from surgical to non-surgical and was the advent of definitive chemoradiation being accepted as a standard-of-care for anal squamous cell carcinomas. Larger doses of radiation are used in modern chemoradiotherapy protocols versus the original Nigro protocol radiotherapy dose.

The National Accreditation Program for Rectal Cancer (NAPRC) was formed to address the differences between patient outcomes in the United States as compared to Europe. According to the American College of Surgeons, outcomes for rectal cancer patients in Europe have for years been significantly better than for those in the U.S. Characterized by the use of multidisciplinary teams to make treatment decisions, the NAPRC standards aim to decrease the average circumferential resection margins, decrease the overall colostomy rate, and increase quality of life as reported by recovering patients.
