Low anterior resection syndrome is a complication of lower anterior resection, a type of surgery performed to remove the rectum, typically for rectal cancer.It is characterized by changes to bowel function that affect quality of life, and includes symptoms such as fecal incontinence, incomplete defecation or the sensation of incomplete defecation (rectal tenesmus), changes in stool frequency ...
The symptoms collectively are referred to as low anterior resection syndrome (LARS) and adversely affect quality of life, sometimes so much so that some patients even prefer to have their stoma-reversal itself reversed, and to live with a permanent colonostomy or iliostomy. [11]
A lower anterior resection, formally known as anterior resection of the rectum and colon and anterior excision of the rectum or simply anterior resection (less precise), 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.
Surgery involving the rectum (e.g. lower anterior resection, often performed for colorectal cancer), radiotherapy directed at the rectum, and inflammatory bowel disease can cause scarring, which may result in the walls of the rectum becoming stiff and inelastic, reducing compliance.
A 2018 review mentions other techniques in addition to strengthening exercises: postural training; education and training for proper lifting mechanisms; manual therapy (which includes soft tissue mobilization); myofascial release; Noble technique (i.e., manual approximation of abdominal muscles during partial sit-up); and abdominal bracing and ...
This procedure aims to improve FI by restoring the anorectal angle and lengthen the anal canal. The main indication is denervation of the pelvic floor (e.g. descending perineum syndrome). After the patient is anesthetized, an incision is made posterior to (behind) the anus and a space between the EAS and IAS is opened up.
Anterior cutaneous nerve entrapment syndrome (ACNES) is a nerve entrapment condition that causes chronic pain of the abdominal wall. [1] It occurs when nerve endings of the lower thoracic intercostal nerves (7–12) are 'entrapped' in abdominal muscles, causing a severe localized nerve (neuropathic) pain that is usually experienced at the front of the abdomen.
Lateral internal sphincterotomy is the preferred method of surgery for persons with chronic anal fissures, and is generally used when medical therapy has failed. [1] It is associated with a lower rate of side effects than older techniques such as posterior internal sphincterotomy and anoplasty, [3] and has also been shown to be superior to topical glyceryl trinitrate (GTN 0.2% ointment) in ...
