The TME technique involves removal of the rectum and the complete perirectal
soft tissue envelope (the mesorectum) using sharp dissection, under direct vision, in the plane between the visceral and parietal pelvic fascia.
Cost-effectiveness of perirectal
surveillance cultures for controlling vancomycin-resistant Enterococcus.
Tumors located below dentate line tend to drain into inguinal lymph nodes; while tumors located above the dentate line typically drain into internal iliac, perirectal
, and mesorectal lymph nodes (24, 25).
MRE also plays a role in the diagnosis of extra-enteric complications of IBD such as perirectal
abscess or sclerosing cholangitis.
Transparietal fixation of the perisigmoid and perirectal
fatty tissue or fixation of the sigmoid colon by appendix epiploicas after mobilization may provide adequate exposure of this field.
For rectosigmoidectomies we sought to ensure the bowel wall distal margin of at least 2 cms and perirectal
fat margin of 4 cms and proximal margin of 5 cms.
lymph node metastasis (N+), the diagnostic accuracy of MDCT was 84.1%.
For example, it was not initially clear which procedure root(s) best applied to abdominal aortic aneurysm repair or whether drainage of a perirectal
abscess should be coded as an open or a percutaneous approach (Utter et al.
pancreative masses, mediastinal masses, perirectal
masses and lymph nodes).
To detect CRE gastrointestinal carriers, fecal samples or rectal/ perirectal
swabs are recommended.
The mass extended upwards from the perirectal
region of the anus, coursing around the rectum with an additional lobulation.
Target volumes consisted of the primary tumor, metastatic lymph nodes, and elective regional lymphatics, including perirectal
, presacral, internal iliac, external iliac, and inguinal lymph nodes.
