What is an abdominoperineal resection surgery?
Surgery to remove the anus, the rectum, and part of the sigmoid colon through an incision made in the abdomen.
What is APR in surgery?
INTRODUCTION. An abdominal perineal resection (APR) includes the resection of the sigmoid colon, rectum, and anus (figure 1) and the construction of a permanent end colostomy.
Is low anterior resection the same as abdominoperineal resection?
Low anterior resection (LAR) and abdominoperineal resection (APR) are the two primary operations for surgical resection of rectal cancer. The decision to perform one operation over the other is based primarily on the tumor location in relation to the sphincter complex.
When do you use LAR vs APR?
In contrast to a LAR, the colostomy is permanent. Many patients would like to avoid a permanent colostomy. When the rectal cancer lies close to the sphincter or anus, an APR is typically recommended.
When is abdominoperineal resection done?
This procedure is most often used to treat rectal cancers located very low in the rectum. Often this surgery occurs after you have completed radiation and/or chemotherapy treatments.
What are the complications of abdominoperineal resection?
The most frequent complications of a perineal resection include hemorrhage, perineal wound complications, persistent perineal sinus, and perineal hernia.
When do you do APR?
APR should be performed in patients in whom negative margin resection (see Table 2, below) will result in loss of anal sphincter function. This includes patients with involvement of the sphincters, preexisting significant sphincter dysfunction, or pelvic fixation, and sometimes is a matter of patient preference.
Why is it called anterior resection?
Other terms used include low anterior resection (LAR), which classically refers to removal of the sigmoid colon and upper rectum and derives its name from the fact that the dissection is below the anterior reflection of the peritoneal lining.
What is a low anterior resection of colon?
Low anterior resection (LAR) LAR is a surgery that’s done to treat rectal cancer. During LAR surgery, the part of your rectum with the cancer will be removed. The remaining part of your rectum will be reconnected to your colon. You’ll be able to have bowel movements (poop) as usual once you recover from your surgery.
Is LAR surgery common?
LAR: A common surgery for rectal cancer in the proximal (upper) two-thirds of the rectum.
What is the primary reason for Aper surgery?
The operation is to remove the diseased bowel. In most cases this will give you the best chance of a cure or significant improvement in your bowel problems.
What is an abdominoperineal resection?
An abdominoperineal resection (APR) is a surgery in which the anus, rectum and sigmoid colon are removed. This procedure is most often used to treat rectal cancers located very low in the rectum. Often this surgery occurs after you have completed radiation and/or chemotherapy treatments. Cleveland Clinic is a non-profit academic medical center.
What is the meaning of abdominoplasty?
(ab-dom’i-nō-per-i-nē’ăl rē-sek’shŭn) A surgical treatment for cancer involving resection of the lower sigmoid colon, rectum, anus, and surrounding skin, and formation of a sigmoid colostomy; performed as a synchronous or sequential transabdominal and perineal procedure.
How is the perineal dissection of the rectum performed?
The perineal dissection may be performed in the prone or lithotomy positions according to surgeon preference without detrimental consequences to oncological outcomes. The anal canal is ideally closed with a purse-string suture at the beginning of the operation prior to rectal mobilization to prevent spillage.
How is a colon resection performed under general anesthesia?
This procedure is performed under general anesthesia at a hospital. Abdominoperineal resection steps include: Preparing the sigmoid colon and rectum for removal: Your surgeon will complete several steps before removing the anus, rectum and sigmoid colon.
