BACKGROUND: The guidelines for colonoscopy present withdrawal time (WT) and adenoma detection rate (ADR) as the quality indicator. The purpose of this retrospective study is to analyze the predicting factors with polyp detection rate (PDR) as a surrogate for ADR by using comprehensive health checkup data, and assess the correlation between PDR per each colonic segment and WT, and factors influencing WT. METHODS: One thousand and thirty six consecutive health checkup cases from April 2015 to March 2016 were enrolled in this study, and 880 subjects who undertook colonoscopy without polyp removal or biopsy were divided into the two groups (polyp not detected group vs polyp detected group)...

OBJECTIVE: Standardized strategy of bowel preparation before video capsule endoscopy (VCE) remains controversial. We aimed to assess the ideal dose of PEG based on small bowel visualization quality (SBVQ), diagnostic yield (DY) and complete rate (CR) of VCE using a network meta-analysis (NMA) of randomized controlled trials (RCTs). METHODS: This NMA included RCTs comparing any of the following bowel preparation interventions for VCE: fasting overnight ('Fast'), 1 liter PEG ('PEG 1L'), 2-liter PEG ('PEG 2L'), or 4-liter PEG ('PEG 4L')...

Caecal volvulus is a rare cause of intestinal obstruction. Caecal volvulus precipitated by acute appendicitis is even rarer. We report an unusual case of caecal volvulus with acute appendicitis as a cause. A 55-year female presented in surgical emergency with 3 days history of abdominal pain, distension and absolute constipation; and 2 days history of vomiting. Her past surgical history was significant for hysterectomy 5 years back. On examination, abdomen was distended and bowel sounds exaggerated. X-ray abdomen erect showed a single large air fluid level in the right hemiabdomen...

High resolution, microultrasound (μUS) scanning of the gastrointestinal (GI) tract has potential as an important transmural imaging modality to aid in diagnosis. Operating at higher frequencies than conventional clinical ultrasound instruments, μUS is capable of providing scanned images of the GI tract with higher resolution. To investigate the use of μUS for this application, a phantom which is cost effective, within ethical guidelines and, most importantly, similar in histology to the human GI tract is necessary...

The role of whole-body positron emission tomography (PET)/computed tomography (CT) with fluorodeoxyglucose ( FDG fluorodeoxyglucose ) is now established in the assessment of many gynecologic and genitourinary malignant tumors. FDG fluorodeoxyglucose PET/CT has been widely adopted for staging assessments in patients with suspected advanced disease, in cases of suspected disease recurrence, and for determining prognosis in a number of malignancies. A number of pitfalls are commonly encountered when reviewing FDG fluorodeoxyglucose PET/CT scans in gynecologic and genitourinary cases; these pitfalls can be classified into those that yield potential false-positive or false-negative results...

BACKGROUND & AIMS: The current guidelines for surveillance after polypectomy do not distinguish between diminutive (1-5 mm) and small (6-9 mm) polyps with low-grade dysplasia (LGD). We aimed to evaluate the risk for advanced neoplasia on follow-up colonoscopy. METHODS: We retrospectively analyzed 443 subjects whose worst finding at index colonoscopy was polypectomy of 1 to 5 or 6 to 9 mm polyps with LGD, and those who underwent a follow-up colonoscopy. RESULTS: During a mean follow-up of 32...

Background and study aims Single-center studies, which were retrospective and/or involved unblinded colonoscopists, have suggested that water exchange, but not water immersion, compared with air insufflation significantly increases the adenoma detection rate (ADR), particularly in the proximal and right colon. Head-to-head comparison of the three techniques with ADR as primary outcome and blinded colonoscopists has not been reported to date. In a randomized controlled trial with blinded colonoscopists, we aimed to evaluate the impact of the three insertion techniques on ADR...

The gastrointestinal tract digests and absorbs dietary nutrients; protects the body against physical and chemical damage from contents in its lumen; provides immunity against external antigens and keeps an optimum environment for the gut microbiota. These functions cannot be performed normally in several diseases of which the following are discussed here: irritable bowel syndrome, inflammatory bowel disease which includes Crohn's disease and ulcerative colitis. Because these diseases are associated with oxidative stress, a host of antioxidant supplements are used for maintenance and recovery of the gut functions...

OBJECTIVES: There is controversy whether constipation as a primary presenting complaint is an indication for diagnostic colonoscopy. Computed tomographic colonography (CTC) is a less invasive and more acceptable alternative. We compared the completion and sensitivity of colonoscopy with CTC in patients who presented with the primary symptom of constipation. METHOD: A retrospective study was conducted which examined the first 100 colonoscopies and 100 CTCs carried out for the primary symptom of constipation from June 2012 to December 2013...
