ABSTRACT
Introduction@#Colonoscopy is the cornerstone in diagnosis and management of colorectal disease allowing direct optical diagnosis, tissue sampling for histological analysis and therapy of colonic lesions. It is a multi-step process and therefore assessment of all aspects of the procedure must be addressed. The main aim of the study is to assess the quality of colonoscopy services in the Colonial War Memorial Hospital from 1st January, 2012 to December 2016.@*Methodology@#A 5-year single-centre, retrospective study.@*Results@#A total of 341 colonoscopies were included in the study. Six Quality indicators of colonoscopy which are applicable to our setting were chosen for the study. The study showed a Cecal Intubation rate of 67% is well below the recommended rate of 90%. The bowel preparation quality is adequate in 53% of the cases compared to a recommended rate of 85%. The withdrawal time has not yet been introduced however, an average withdrawal time of above 6 minutes is recommended for a quality colonoscopy. Acquisition of biopsies in diarrhoea patients was 79% (100% tissue acquisition rate was recommended for quality of colonoscopy). @*Conclusion@#The quality of colonoscopy services carried out at the Colonial War Memorial Hospital has room for improvement in the parameters determining the quality of colonoscopies.
ABSTRACT
Objective To find the related factors of the unsuccessful unsedated colonoscopy. Methods Clinical data of 1 726 consecutive subjects who underwent colonoscopy without sedation from April 2014 to January 2015 at the second affiliated hospital of Soochow university were analyzed. Data included characteristics of the patients (age, gender, body mass index, degree of education, the bowel-cleaning drugs, previous colonoscopy experience, bowel habits, history of chronic disease, history of sport, history of abdominal or pelvic surgery, the indication of colonoscopy, mood, quality of bowel preparation, and presence/absence of colonic diverticulum), the characteristics of the physicians (procedure experience, the instrument handling method). These factors were analyzed to evaluate their impact on result of unsedated colonoscopy. Results This study included 1 726 patients (male/female: 927/799). These patients' average age was 50.04 years old, the cecal intubation rate was 91.6%, and the average intubation time was 10.27 minutes. The multiple regression analysis showed the elderly patient, lower BMI, irritability, consti﹣pation, poor bowel preparation were associated with the lower cecal intubation rate. Conclusions The elderly patient, lower BMI, irritability, constipation and poor bowel preparation were associated with the failure of unsedated colonoscopy. In clinical practice, quality improvement programs are needed to improve the rate of total colonoscopy.
