There have been limited data regarding screening colonoscopy in Thailand.... The objectives of this study were therefore to determine polyp and adenoma detection rates in Thai people, to evaluate the incidence of colorectal cancer detected during screening colonoscopy and to determine the endoscopic findings of the polyps which might havePublication Metadata only Colonoscopic perforation: A report from World Gastroenterology Organization endoscopy training center in Thailand(2008-11-21) Varut Lohsiriwat; Sasithorn Sujarittanakarn; Thawatchai Akaraviputh; Narong Lertakyamanee; Darin Lohsiriwat; Udom Kachinthorn; Mahidol Universitycolonoscopies and sigmoidoscopies performed between 1999 and 2007 in the Endoscopic unit, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok were reviewed.

Most surgeons started CRC screening in an average-risk patient at the age of 50 years and did no screening in populations with age above 80 years. Colonoscopy is the most popular investigation used in CRC screening, followed... by fecal occult blood testing and double contrast barium enema. When the surgeons themselves were subjected to CRC screening, colonoscopy was also the favorite investigation used. About 3-18% of surgeons showed interest in CRC screening with computedPublication Metadata only Colonoscopic perforation: Incidence, risk factors, management and outcome(2010-01-28) Varut Lohsiriwat; Mahidol UniversityThis review discusses the incidence, risk factors, management and outcome of colonoscopic perforation (CP). The incidence of CP ranges from 0.016% to 0.2% following diagnostic colonoscopies and could be up to 5% following some colonoscopic... interventions. The perforations are frequently related to therapeutic colonoscopies and are associated with patients of advanced age or with multiple comorbidities. Management of CP is mainly based on patients' clinical grounds and their underlying colorectal
