A 65-year-oldman presented to the emergency department with a foreign body in his rectum. He had inserted a Cuban cigar case into his anus approximately 9 hours before admission. The case had no sharp edges, and its cap was on. The patient’s abdomen was soft and not distended. Abdominal radiography showed a long, radiopaque, cylindrical foreign body in the rectum and sigmoid (●" Fig.1), with no...

To investigate the reason why, during a mass contraction, the stool moving from the colon to the sigmoid colon stops short of the rectosigmoid junction (RSJ) instead of passing directly to the rectum, and whether the sigmoid colon and RSJ share in the anorectal continent mechanism, 12 mongrel dogs were studied. Under anesthesia, the anorectum was excised, sigmoid colon and RSJ were mobilized an...

Patients with irritable bowel syndrome (IBS) with diarrhea (IBS-D) carrying human leukocyte antigen (HLA)-DQ2/8 genotypes benefit from gluten withdrawal. Our objective was to compare gastrointestinal barrier function, mucosal inflammation, and transit in nonceliac IBS-D patients and assess association with HLA-DQ2/8 status. In 45 IBS-D patients who were naive to prior exclusion of dietary glute...

Carpeted villous adenomas of rectum may be extensive and not suitable for transanal excision or Endoscopic mucosal resection. We present a case of such lesion extending from anorectal junction to rectosigmoid region. After biopsy and staging, this was managed by a sphincter saving procedure, i.e. a combination of transabdominal total mesorectal excision and transanal intersphincteric dissection...

Personal watercrafts (PWC), also known as jet skis, seadoos, and wave-runners have risen in popularity since their introduction in the 1970s. Hydrostatic rectal injury is a rare presentation of passengers thrown off a PWC. The perforation of the rectum is owing to the excessive hydrostatic force of water exerted through the anal canal. We present the first case of rectosigmoid perforation secon...

Sudeck's critical point at the rectosigmoid junction is described as the point of origin of the last sigmoid arterial branch, originating from the inferior mesenteric artery (IMA). There is controversy on the importance of Sudeck's point, and the frequency in which the anastomosis is found. Furthermore, the diameter of the anastomosis, if present, may also impact on the viability of the caudal ...

BACKGROUND The regulations of the Norwegian Patient Register (NPR) and the Cancer Registry of Norway (CRN) allow linkage of the registries for evaluation of completeness and validity of data. MATERIAL AND METHOD Data on patients registered as having C18 (colon cancer), C19-C21 (cancer of the rectum, rectosigmoid junction or anus), C33-C34 (cancer of the lungs or trachea), C50 (breast cancer),...
