The tumours of the small intestine constitute about 5% of all tumours of the gastrointestinal tract. These tumours are about equally divided between benign and malignant varieties. The autopsy incidence of small intestine tumours is about 0.2%. Lipoma of the small intestine is very rare and such tumour causing intussusception is also rare. We present a case of lipoma of the ileum causing intuss...

Small intestine is the longest organ in the gastrointestinal tract where much of the digestion and the food absorption take place. Wireless video capsule endoscope (VCE) is the first device taking 2-D pictures from the lesions and the abnormalities in the entire length of the small intestine. Since precise localization and mapping inside the small intestine is a very challenging problem, we can...

Methyl(acetoxymethyl)nitrosamine (DMN-OAc) when in jected i.p. in Sprague-Dawley Charles River CD rats selectively induces epithelial tumors of the intestines. Males are more severely affected than females. To determine whether the strain of rat determines the quantity or type of tumors induced, 5week-old male and female rats of Sprague-Dawley (SD), Buffalo (BUF) and Fischer (F344) strains were...

Commensal microflora engages in a symbiotic relationship with their host, and plays an important role in the development of colorectal cancer (CRC). Pathogenic bacteria promote chronic intestinal inflammation and accelerate tumorigenesis. In sporadic CRC, loss of an effective epithelial barrier occurs at early stage of CRC development. As a result, non-pathogenic bacteria and/or their products ...

The most significant development in liver transplantation in the USA over the past year was the full implementation of the MELD- and PELD-based allocation policy in March 2002, which shifted emphasis from waiting time within broad medical urgency status to prioritization by risk of waiting list death. The implementation of this system has led to a decrease in pretransplant mortality without inc...

Nitrogen absorption from the large intestine, largely as ammonia and possibly as amino acids (AAs), is generally thought to be of little nutritional value to nonruminant animals and humans. Ammonia-nitrogen absorbed from the large intestine, however, may be recycled into the small intestine as urea and incorporated into microbial AAs, whichmay then be used by the host. A cecal infusion study wa...

Cervical cancer metastasis to the small intestine is a rare occurrence that is easily misdiagnosed as a small bowel obstruction. The present study reports the case of a 46-year-old cervical cancer patient with metastasis to the small intestine, which presented as an acute abdomen due to intestinal obstruction. Enteroscopy revealed no primary intestinal tumors. The patient underwent exploratory ...

various clinical signs that may result from removal of a large part of the small intestine with or without removal of part of the large intestine. SBS is common in humans and, especially, infants but is uncommon in dogs and cats because most animals that need large portions of intestine removed are euthanized. The decreased absorptive surface area of the small intestine due to extensive resecti...

Ascariasis, a worldwide parasitic disease, is regarded by some authorities as the most common parasitic infection in humans. The causative organism is Ascaris lumbricoides, which normally lives in the lumen of the small intestine. From the intestine, the worm can invade the bile duct or pancreatic duct, but invasion into the gallbladder is quite rare because of the anatomical features of the cy...

more energy was transferred from the stomach to the intestine during the first 80 minutes after taking the meal. A high body weight was also associated with a rapid transit through the proximal 70 cm of intestine and the passing of a substantial part of the meal calories to the lower intestine. These circumstances favour a fast incorporation of fed calories. In subjects with lower body weights ...
