Colonic polyps: Experience from King Khalid University Hospital
1Division of Gastroenterology, Department of Medicine, King Saud University, Riyadh, Saudi Arabia.
Abstract:
To find out the frequency rate and anatomical distribution of colonic polyps in patients attending King Khalid University Hospital, we retrospectively reviewed all colonscopic files between 1406-1415 AH. Of 2772 patients who underwent colonoscopic examination, 109 patients (75 males and 34 females, mean age of 43.5 +/- 19 years) were found to have a total of 188 polyps. There were 73 Saudis; 47 males with a mean age of 48.6 +/- 17.4 years and 26 females with a mean age of 42.4 +/- 17.9 years. Polyp frequency rates in the whole group and in Saudi patients were 3.93% and 4.0%, respectively. There were 124 (66%0 polyps which were sessile. The majority of polyps (82%) were located in the left side of the colon. Tubular and tubulovillous adenoma constituted 89.5% of all histological reports of neoplastic polyps. Synchronous colonic pathology was observed in 32 (29.4%) patients. This shows that the colonic polyp frequency rate is low. The left side of the colon accommodated most of these polyps.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
