OBJECTIVE To evaluate whether prolonged waiting times for colonoscopy in public hospitals could result in delayed diagnosis of colorectal carcinoma. DESIGN, SETTING AND PATIENTS Analysis of all outpatient colonoscopies performed at a Western Australian tertiary teaching hospital, 1 November 2003 - 31 October 2005. Colonoscopy data, corresponding pathological findings, category of urgency at r...

Missed polyps are frequently observed in surveillance colonoscopy or referral resection. We evaluated the polyp missing rate and its associated risk factors in patients who were referred to a tertiary hospital for endoscopic resection of advanced colorectal neoplasia.A total of 388 patients with advanced neoplasia who underwent colonoscopy in their referring hospitals and only endoscopic resect...

Objective- The aim of this study was to evaluate the efficacy and safety of senna as an alternative or adjunct to polyethylene glycol (PEG) solution in dogs using colonoscopy and radiography.Design - Experimental study.Animals - 20 adult mongrel healthy dogs.Procedures- Dogs were randomly allocated to receive 1 of 4 different bowel preparation regimens including PEG, senna or ...

BACKGROUND & AIMS We investigated the safety and effectiveness of early colonoscopy (performed within 24 hours of hospital admission) for acute lower gastrointestinal bleeding (LGIB) vs elective colonoscopy (performed 24 hours after admission). METHODS We conducted a retrospective study by using a database of endoscopies performed at the National Center for Global Health and Medicine in Tokyo...

Evaluating predictive factors for high-risk adenomas at the third colonoscopy based on two prior colonoscopies may help evaluate high-risk adenoma at the third colonoscopy. We analyzed clinical data of 131 patients at Severance Hospital from January 1997 to January 2011. All of them underwent two subsequent colonoscopies after removal of adenomas during an initial colonoscopy. Among 20 patients...

Background/Aim. High-quality colonoscopy is needed to reduce the morbidity and mortality of colorectal cancer. Full-spectrum endoscopy (FUSE) has recently shown potential in improving adenoma detection during colonoscopy. This study aimed to evaluate the feasibility and utility of FUSE colonoscopy. Methods. From April 2015 to February 2016, 130 patients underwent FUSE colonoscopy for screening ...

Aim. To evaluate patient satisfaction towards an outpatient colonoscopy service and analyze areas of dissatisfaction for potential improvement. Method. Consecutive patients attending the outpatient diagnostic colonoscopy service in University of Malaya Medical Centre between 1st February and 31th July 2010 were interviewed using a questionnaire modified from the modified Group Health Associatio...

BACKGROUND Inadequate bowel preparation during screening colonoscopy necessitates repeating colonoscopy. Studies suggest inadequate bowel preparation rates of 20-60%. This increases the cost of colonoscopy for our society. AIM The aim of this study is to determine the impact of inadequate bowel preparation rate on the cost effectiveness of colonoscopy compared to other screening strategies fo...

OBJECTIVES Obesity is an important risk factor for the development of colorectal cancer (CRC). Although the impact of bariatric surgery on CRC is conflicting, its impact on precursor lesions is unknown. The aim of this study was to determine whether bariatric surgery before index screening colonoscopy is associated with decreased development of colorectal adenomas. METHODS We performed a retr...

Colonoscopy is the most widely used screening modality for the detection and removal of colon polyps and for the prevention of colorectal cancer. To identify all colon lesions and reduce the risk of colorectal cancer, it is important to perform a complete colonoscopy. The success of screening colonoscopy depends upon several parameters, including bowel preparation and adenoma detection rate. In...
