Ann Saudi Med 2006;26(4):315-317 Postoperative intestinal obstruction (POI) is a well-recognized complication usually related to peritoneal adhesions. It is an uncommon and frequently overlooked cause of intestinal obstruction and accounts for 5% to 10% of postoperative ileus in children.1 The actual incidence of postoperative intussusception following laparotomy is low and varies from 0.01 to ...

Introduction A Meckel’s diverticulum (MD) is the most common congenital anomaly of the gastro-intestinal tract, and can present diagnostic and surgical challenges. Arising from failure of the omphalomesenteric duct to close properly, MD can occur in up to 2% of the population and can manifest as obscure gastrointestinal bleeding, Meckel’s diverticulitis, obstruction, and intussusception [1]. Wh...

Abstract Background Identification and photo-documentation of the ileocecal valve (ICV) appendiceal orifice (AO) confirm completeness colonoscopy examinations. We hypothesized that an artificial intelligence (AI)-empowered solution could help us automatically differentiate anatomical landmarks such as AO ICV from polyps normal colon mucosa. Purpose aimed to develop test a deep convolutional neu...

Stereotypical changes in pH occur along the gastrointestinal (GI) tract. Classically, there is an abrupt increase in pH on exit from the stomach, followed later by a sharp fall in pH, attributed to passage through the ileocecal region. However, the precise location of this latter pH change has never been conclusively substantiated. We aimed to determine the site of fall in pH using a dual-scint...

the opacities were tablets trapped in the right colon by a neoplastic stricture (Fig. 2). At laparotomy a tumour was found encircling and obstructing the colon 12 cm above the ileocaecal valve. A right hemicolectomy was performed. The tumour was 8 cm long and was invading but not perforating the muscle coat. The lymph nodes were not involved. Several of the tablets were enmeshed in the papillae of
