Small intestinal neuroendocrine tumors (SI-NETs) are the most common neoplasms of the small bowel. The majority of tumors are located in the distal ileum with a high incidence of multiple synchronous primary tumors. Even though up to 50% of SI-NET patients are diagnosed with multifocal disease, the mechanisms underlying multiple synchronous lesions remain elusive.

In the mid-seventies, biliopancreatic diversion became popular as weight-loss surgery procedure. This bariatric procedure combines distal gastric resection and intestinal malabsorption, leading to greater weight loss and improvement of co-morbidities than other bariatric procedures.

Meckel’s diverticula are a rare cause of small intestinal strangulation, diagnosed at laparotomy or necropsy. This congenital anomaly of the gastrointestinal tract originates from a remnant of the vitelline duct. In reported equine cases, they present as a full-thickness diverticulum on the antimesenteric border of the distal jejunum or proximal ileum.

Hirschsprung disease (HSCR), which is congenital obstruction of the bowel, results from a failure of enteric nervous system (ENS) progenitors to migrate, proliferate, differentiate, or survive within the distal intestine. Previous studies that have searched for genes underlying HSCR have focused on ENS-related pathways and genes not fitting the current knowledge have thus often been ignored.

Periampullary adenocarcinomas comprise pancreatic, distal bile duct, ampullary and duodenal adenocarcinoma. The epithelia of these anatomical structures share a common embryologic origin from the foregut.

Approximately 50 % of gastric adenocarcinomas belong to a molecular subgroup characterised by chromosomal instability and a strong association with the intestinal histological subtype. This subgroup typically contains alterations in the receptor tyrosine kinase–RAS pathway, for example EGFR or HER2 gene amplifications leading to protein overexpression.

The present study was conducted on 24 Uttara fowl birds. The gross and ultra-structural features with their age-related changes in the large intestine were studied. The length and weight of caeca and colorectum and their diameter and thickness at proximal, middle and distal portions in all the age groups increased with advancing age. The left caeca were slightly longer and heavier than right caecum in all studied age groups.
