The authors report the case of a 63-year-old man who underwent an open adrenalectomy for a synchronous, malignant, metastatic left adrenal tumor and a total colectomy for T3N0M1 (stage 4) primary, malignant colon cancer. Two polypoid lesions, one measuring 40 mm × 30 mm × 30 mm and the other measuring 20 mm × 10 mm × 10 mm, were found in the ascending colon and rectosigmoid (RS) junction, respe...

A 65-year-old man with no significant past medical history was admitted to an outside hospital with 1.5 months of crampy, lower abdominal pain associated with rectal urgency and tenesmus. Initial computed tomography showed thickening of his rectosigmoid and mid to distal descending colon; follow-up colonoscopy revealed inflammation of the affected areas with focal lamina propria vascular conges...

Background: Intussusception is a frequent cause of bowel obstruction in children but is rare in adults. In about 90% of cases, adult intussusception has identifiable cause acting as the lead point. A lipoma may develop as a benign tumor in any organ but rarely in large or small intestines. Intussusception due to a gastrointestinal lipoma constitutes an infrequent clinical entity. We present a c...

BACKGROUND To achieve optimal cytoreduction for advanced-stage ovarian cancer, modified posterior exenteration is the most frequently performed bowel surgery. We assessed the extents of tumor spreading in the rectosigmoid wall and pelvic side wall in modified posterior exenteration specimens during primary debulking surgery (PDS) and interval debulking surgery (IDS) following neoadjuvant chemot...

Gastrointestinal xanthomas are characterized by foamy cytoplasmic cells containing lipid in lamina propria, and occur almost in the gastric mucosa. Colonic xanthomas have been described in rare case. All reported colonic xanthomas were located in rectosigmoid. Rectosigmoid xanthomas have tended to exhibit small polypoid lesion, on the contrary flat in stomach. We report a case of xanthoma on as...

Background Hirschsprung-associated enterocolitis physiopathology likely involves disturbed interactions between gut microbes and the host during early neonatal period. Our objective was to create a porcine model of iatrogenic aganglionosis evaluate impact enteric nervous system (ENS) on microbiota intestinal barrier postnatal development. Methods Under general anesthesia, rectosigmoid serosa 5-...

Purpose Diagnosis of colorectal carcinoma on contrast-enhanced CT relies on demonstration of rectosigmoid wall thickening, perirectal fat stranding, and perirectal lymph nodes. Wall thickening may be the only sign in early carcinoma, and may be mimicked by spasm or adherent faecal matter. Rectosigmoid carcinoma may result in earlier venous return in inferior mesenteric vein (IMV) compared to su...

BACKGROUND/AIMS Endoscopic mucosal resection (EMR) of large colorectal lesions is associated with increased procedural time. The objective of this study was to evaluate the effect of double-channel gastroscope (DCG) use on the procedural time of EMRs in the rectosigmoid area. METHODS All EMRs for sessile or flat rectosigmoid lesions ≥2 cm performed between July 2011 and September 2012 were re...

The colonic response to a meal is often used to test the effect of drugs on colonic motility, but this test is hindered by its inconsistency. This study has used multiple manometric sensors situated in the rectosigmoid region to investigate whether recording of the site and type of contraction offers a clear discrimination of the colonic response to a meal and the effect of drugs. Two studies w...

BACKGROUND Early manifestations of pediatric inflammatory bowel disease (IBD) can be relatively nonspecific. Initial mucosal biopsies may not be conclusive, delaying the diagnosis until subsequent biopsies demonstrate typical histologic features of IBD. We hypothesized that certain inflammatory cell types may be utilized as early histologic indicators of IBD in children. METHODS A retrospecti...
