conclusions cpaa provided not only better functional results than scaa, but also improved quality of life, thus may be the better choice. background the tendency towards sphincter preserving for low rectal cancers with low anterior resection, has led to the technique of straight coloanal anastomosis (scaa) or colonic j-pouch anal anastomosis (cpaa). objectives the aim of our study was to compar...

background: colorectal carcinoma is the third most common cause of death in iran. this study was performed in order to determine the appropriate distal clearance margin (dcm) for resection of rectal cancer in patients who undergo neoadjuvant chemoradiotherapy for sphincter preserving procedure. materials and methods: this was a cross-sectional study conducted in shahid faghihi hospital of shira...

PURPOSE Lymph-node metastasis is the most important predictor of survival in stage III rectal cancer. The number of metastatic lymph nodes may vary depending on the level of specimen dissection and the total number of lymph nodes harvested. The aim of this study was to evaluate whether the lymph node ratio (LNR) is a prognostic parameter for patients with rectal cancer. METHODS A retrospectiv...

BACKGROUND There may be a weak association between total alcohol intake and colorectal cancer but the effect of different types of alcohol and effect on colon subsites have not been investigated satisfactorily. AIMS To investigate the relationship between amount and type of alcohol and the risk of colon and rectal cancer. SUBJECTS A population based cohort study with baseline assessment of ...

There are few reported cases of colorectal metastasis from cancers of other organs, particularly other segments of the colon. Here we describe the long-term survival of a 68-year-old male patient with metachronous rectal metastasis from cecal cancer who underwent repetitive resection and chemotherapy. The patient underwent ileocecal resection and hepatectomy for cecal cancer with liver metastas...

We examined associations of dietary patterns with colon cancer risk in African Americans and Whites from a case-control study in North Carolina. Incident colon cancer cases, 40 to 80 yr (n = 636), and matched controls (n = 1,042) were interviewed in person to elicit information on potential colon cancer risk factors. A validated food frequency questionnaire adapted to include regional foods cap...

High-resolution MRI is the best method of assessing the relation of the rectal tumor with the potential circumferential resection margin (CRM). Therefore it is currently considered the method of choice for local staging of rectal cancer. The primary surgery of rectal cancer is total mesorectal excision (TME), which plane of dissection is formed by the mesorectal fascia surrounding mesorectal fa...

PURPOSE Locally advanced rectal cancer may require an intraoperative decision regarding curative multivisceral resection (MVR) of adjacent organs. In bulky tumor cases, ensuring sufficient distal resection margin (DRM) for achievement of oncologic safety is very difficult. This study is designed to evaluate the adequate length of DRM in multiviscerally resected rectal cancer. METHODS A total ...

BACKGROUND Transanal endoscopic microsurgery (TEM) is a newly developed, minimally invasive technique for the local resection of rectal tumours. Its place needs to be defined. METHODS Literature review. RESULTS Local excision of rectal tumours is associated with low mortality and morbidity. It is indicated in adenomas for curation and in rectal cancer for palliation. Transanal resection is ...
