Colonoscopy is a key investigation used to exclude large bowel pathologies including surveillance for CRC (Colorectal cancer) Poor bowel preparation (bowel prep) is one of the most important factors affecting its diagnostic yield. Different formulations of bowel prep are currently in use depending upon patient tolerance, indication & co-morbidities. In University Hospital Llandough we retrospectively reviewed the outcome of colonoscopies performed over period of 3 months, in relation to the type and outcome of bowel preparations used...

INTRODUCTION AND AIMS: A high quality colonoscopy is key in preventing colorectal cancer, but the risk of colorectal cancer (CRC) exists. The aims of the study were to investigate the incidence, characteristics and predictive factors of post-colonoscopy colorectal cancer (PCCRC). MATERIAL AND METHOD: A retrospective and prospective observational study was designed. A population undergoing colonoscopy between 1-01-1997 and 31-12-2014 was included. We analysed demographic variables, characteristics of the diagnostic colonoscopy of CRC, of the previous ones and the lesions found in them...

Effective bowel cleansing is crucial for high quality colonoscopy. A notable portion of patients still present with low quality bowel preparation prior to their colonoscopy, compromising the overall quality of their colonoscopy. Areas covered: This review focuses on the main strategies that can improve the cleansing quality with a special interest on those clinical conditions that have been associated with a poor bowel preparation quality, such as patients with chronic constipation, history of bowel resection, liver cirrhosis, diabetes mellitus and chronic kidney disease...

OBJECTIVE: Enema administration in the morning of routine colonoscopy is known to be useless. However, the potential bowel cleansing effects of distal colon emptying with enema prior to purgatives are not known. The aim of this study is to investigate the effects of enema use before purgatives in preparation for colonoscopy. MATERIAL AND METHODS: Two hundred twenty-seven patients were randomly assigned into three groups; enema before purgative use, enema after purgative use, and no enema...

Colorectal cancer is a leading cause of morbidity and mortality worldwide in both men and women. The gut microbiome is increasingly recognized as having an important role in human health and disease. Fusobacterium has been identified in former studies as a leading gut bacterium associated with colorectal cancer but it is still not clear if it plays an oncogenic role. In the current study, fecal samples were collected prior to bowel preparation from participants of screening colonoscopy in the German BliTz study...

BACKGROUND: A recommendation to undergo a colonoscopy, an invasive procedure that requires commitment and motivation, planning (scheduling and finding a driver) and preparation (diet restriction and laxative consumption), may be uniquely challenging for individuals with multiple chronic conditions (MCCs). This qualitative study aimed to describe the barriers and facilitators to colonoscopy experienced by such patients. MATERIALS AND METHODS: Semistructured focus groups were conducted with male Veterans who were scheduled for outpatient colonoscopy and either failed to complete the procedure or completed the examination...

OBJECTIVES: Precolonoscopy dietary regimens often are restricted to clear liquids; however, the superiority of a clear liquid diet (CLD) for bowel preparation quality is ambiguous. We performed a meta-analysis of randomized trials comparing bowel preparation outcomes between a low-residue diet (LRD) or regular diet (RD) compared with a CLD. METHODS: MEDLINE, clinicaltrials.gov, Cochrane Central Register, Scopus, Embase, Cumulative Index to Nursing and Allied Health Literature, and the Web of Science databases were used to conduct a search for randomized controlled trials from 1976 to March 2015...

BACKGROUND AND STUDY AIMS : Some guidelines recommend a minimum standard of 90 % cecal intubation rate (CIR) in routine clinics and 95 % in screening colonoscopy, while others have not made this distinction - both with limited evidence to support either view. This study questions the rationale for making such differentiation. PATIENTS AND METHODS:  We assessed cecum intubation rates amongst colonoscopies recorded in the Norwegian national quality register Gastronet by 35 endoscopists performing both clinical and screening colonoscopies...

BACKGROUND AND STUDY AIMS:  Patients undergoing bowel preparation for colonoscopy are at risk of potentially severe adverse events such as large-bowel obstruction (LBO) and perforation. These patients usually need emergency surgery and the consequences may be fatal. Little is known about the risk factors for LBO and perforation in these circumstances. We sought to establish the natural history of LBO and perforation caused by oral preparation for colonoscopy. PATIENTS AND METHODS:  We retrospectively analyzed data from 20 patients with LBO or perforation associated with oral preparation for colonoscopy...

BACKGROUND: Colon capsule endoscopy (CCE) offers direct mucosal visualisation without sedation or gas insufflation required in conventional colonoscopy (CC). However, evidence for the role of CCE as an adjunct or alternative to CC remains equivocal. In this observational cohort study, we report our experience of using CCE to investigate patients with suspected colon pathology at a tertiary referral centre. METHODS: From 2007-2015, consecutive patients requiring colonoscopy were recruited from a tertiary care centre in Malmo, Sweden...

OBJECTIVES: A cecal intubation rate (CIR) of >90% is a well-accepted quality indicator of colonoscopy and is consequently monitored within endoscopy units. Endoscopists' desire to meet this target may mean that incomplete colonoscopies are recorded as flexible sigmoidoscopies. The aim of this study was to examine whether the conversion of requested colonoscopies is a clinically significant phenomenon and whether this impacts upon the measurement of quality indicators. METHODS: A retrospective review of all flexible sigmoidoscopies performed between 1 January 2015 and 31 December 2015 at Nottingham University Hospitals, Sheffield Teaching Hospitals, and Cambridge University Hospitals was performed...

BACKGROUND: Collagenous colitis (CC) is by definition a histological diagnosis. However, colonoscopy often reveals characteristic endoscopic findings. The aim of this study was to evaluate the frequency and type of endoscopic findings in patients diagnosed with CC in 4 participating centers. METHODS: This was a retrospective study; the databases of 2 university hospitals in Edinburgh (Scotland) and Malmö (Sweden), and 2 district general hospitals in Tomelloso (Spain) and Gateshead (England) were interrogated for patients diagnosed with CC between May 2008 and August 2013...

SUMMARY: Colonoscopy is a useful tool in modern medicine and is increasingly employed for both diagnostic and treatment reasons. However, its effectiveness is highly reliant on the quality of bowel cleansing. Among different bowel-cleansing agents available, PEG (polyethylene glycol) is considered to be the safest cleansing agent, especially in relation to fluid and electrolyte problems. We present here a case of severe symptomatic hyponatremia that developed after the use of PEG for an elective colonoscopy...

BACKGROUND/AIMS: Low-volume polyethylene glycol (PEG) bowel preparations are better tolerated by patients than high-volume preparations and may achieve similar preparation quality. However, there is little data comparing their effects on a recommendation for an early repeat colonoscopy (because of a suboptimal preparation), procedure times, adenoma detection rate (ADR), and advanced adenoma detection rate (AADR). METHODS: This is a retrospective cohort study of outpatient colonoscopies performed during a one-year period at a single academic medical center in which low-volume MoviPrep® (n = 1841) or high-volume Colyte® (n = 1337) was used...
