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 colon.
Lymph node involvement and lymphovascular invasion in deep infiltrating
rectosigmoid endometriosis.
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 colon).
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]).
Hydrostatic
rectosigmoid 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.
