What is difference between LAR and APR?
An APR, generally, results in a worse quality of life than the less invasive lower anterior resection (LAR). Thus, LARs are generally the preferred treatment for rectal cancer insofar as this is surgically feasible.
What is an APR in colorectal surgery?
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?
Abdominoperineal resection involves removing the tumor along with the anal canal and sphincter complex, creating a permanent end colostomy. To qualify for an LAR, both the tumor and the distal margin must allow preservation of the sphincter complex.
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.
What is the difference between low anterior resection and APR?
Low anterior resection and APR are two major surgical techniques used in lower and middle rectal cancers. Low anterior resection can provide comparable local control, disease free and overall survival rates compared with APR in eligible patients with lower and middle rectal cancer.
Does low anterior resection improve survival rates in Lower and middle rectal cancer?
Low anterior resection can provide comparable local control, disease free and overall survival rates compared with APR in eligible patients with lower and middle rectal cancer. None of the authors has any conflict of interest, financial or otherwise. This study was supported by Shiraz University of Medical Sciences.
What is an anterior resection of the rectum?
Anterior resection (AR) is most commonly performed for patients with high-to-mid level rectal tumors in the setting of rectal adenocarcinoma. AR can also be performed for benign conditions such as diverticular disease and other malignancies of the rectum.
What is the difference between APR and Lar for rectal cancer?
LAR can provide comparable local control, disease free and overall survival rates compared with APR in eligible patients with lower and middle rectal cancer. LAR can provide comparable local control, disease free and overall survival rates compared with APR in eligible patients with lower and middle rectal cancer.
