Crohn's disease is not usually regarded as a premalignant state. Recent reviews of the literature1' 2 make scant reference to an association of regional enteritis with carcinoma. However, at the World Congress of Gastro-enterology, I958, Crohn observed that he had seen two cases of carcinoma of the small intestine co-existing with regional enteritis.3 Rare cases of carcinoma arising in patients...

BACKGROUND Liposarcoma is one of the most common soft tissue sarcoma of adult life, usually occurring in the retroperitoneum and the extremities. Primary liposarcoma of the colon is very rare. The optimal treatment has not been established due to the small number of cases reported. We report a case of primary liposarcoma of the colon presenting as a massive intraluminal lesion. CASE PRESENTAT...

Butanoic acid plays a significant role in the maintenance of mucosal health and is the preferred energy substrate for the cells in the colon. Here, butanoic acid was selectively conjugated to the secondary hydroxyl group of β -cyclodextrin through ester bond using sodium hydride as the deprotonation reagent. The preliminary release behaviors of butanoic acid in rat gastrointestinal tract conten...

Bochdalek hernias are a rare diaphragmatic hernia, usually diagnosed in childhood. We report case of large hernia containing omentum, stomach, left colon and some small bowel (jejunum) including mesentery, the superior pole kidney, spleen tail pancreas adulthood. Our patient underwent laparoscopic repair this massive with composite mesh an excellent post-operative outcome.

The aim of this study was to characterize rat small intestinal and colon tissue slices as a tool to study intestinal metabolism and to investigate gradients of drug metabolism along the intestinal tract as well as drug-induced inhibition and induction of biotransformation. Tissue morphology and the intestinal mucus layer remained intact in small intestinal and colon slices during 3 h of incubat...

Background: A 25-year old female presented to the Emergency Department with intermittent abdominal pain. Computed tomography imaging demonstrated multiple fat-density tumors in the small intestine and colon associated with two long-segment intussusceptions. Methods: Colonoscopy showed a partially obstructing multilobulated mass in the descending colon; biopsy was non-diagnostic. At exploratory ...

The alimentary tract is the main source of 5-hydroxytryptamine (5HT, serotonin) in the body, but the physiological role of this amine is as yet uncertain. Bulbring and Crema (1958) have shown that 5HT potentiates the peristaltic reflex when applied to the mucosal surface of the guinea-pig ileum in vitro. In man, intravenous injections of serotonin stimulate pressure waves in the jejunum and ile...

We report a case of ileal atresia with meconium peritonitis evaluated by fetal MRI. Prenatal ultrasounds in the third trimester initially demonstrated a cystic abdominal mass that resolved with development of dilated bowel loops. Fetal MRI at 32 weeks gestation identified a perihepatic collection with several dilated small bowel loops and normal sized meconium filled rectosigmoid consistent wit...

The most frequent cause of pseudomembranous colitis is Clostridium difficile (C. difficile) infection. This type of colitis is characterized by an endoscopic pattern of numerous small, yellowish or whitish plaques diffusely distributed, which typically compromises the rectum extending to proximal colon. Occasionally, the pseudomembranes compromise only the transverse or right colon, but their e...
