The anatomical shelter theory contributes to lesions within the pelvis, with the rectosigmoid
colon blocking the cephalad flow of effluxed menstrual blood from the pelvis, thus leading to a preponderance of lesions in the pelvis and along the rectosigmoid
Lymph node involvement and lymphovascular invasion in deep infiltrating rectosigmoid
Site of Transition Zone Site Number (n) Percentage (%) Rectosigmoid
31 49.21 Sigmoid 29 46.03 Rectum 3 4.76 Table 2.
For example, if a patient had right colectomy, the bowel cleansing quality was assessed in the remnant colon segment divided into three parts (transverse colon, descending colon, and rectosigmoid
Clostridium difficile infection and mycophenolate mofetil (MMF) toxicity from a rectosigmoid
colon biopsy (E) and MMF toxicity from a stomach biopsy (F) (hematoxylin-eosin, original magnification X20 [A, C, E, and F]; CMV immunohistochemistry, original magnification X20 [B and D]).
perforation: a rare personal watercraft injury.
"Real-time CAD can achieve the performance level required for a diagnose-and-leave strategy for diminutive, non-neoplastic rectosigmoid
polyps," the authors write.
Our patient showed rectosigmoid
involvement with severe active inflammation.
As will be noted, when compared with segmental rectosigmoid
resection for deep infiltrating endometriosis, the risk of temporary ileostomy, bowel complications, and rectal and bladder dysfunction are all decreased.
Mural soft tissue thickening of rectosigmoid
area was also noted which was approximately 10.2cms.
The location of ulcers in the rectum was classified like that used for colorectal cancer: rectosigmoid
(Rs), rectum above the peritoneal reflection (Ra), or rectum below the peritoneal reflection (Rb).
The lower rectosigmoid
colon is the most common localization of the disease, followed by the rectovaginal septum, the distal part of the small intestine, the cecum, and the appendix.
