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...

Background Adequate polyp detection is crucial to colonoscopy; however, detection can be impaired. In particular, flat polyps located behind folds or near the colonic flexures appear to be a problem. We present a cheap and easily adjustable 3D-printed tool to enhance the view of a standard colonoscope using additional commercially available sideoptics. Materials and methods A cap adjustable to a standard endoscope was printed by a 3 D printer and had two microcameras fixed to offer two additional views...

BACKGROUND: Sessile serrated adenomas/polyps (SSA/P) are an under-recognized disease with a unique malignant pathway. Improved endoscopic recognition and pathological interpretation is needed. AIMS: To determine whether an educational intervention that improved adenoma detection rate (ADR) could improve SSA/P detection rate after reclassification of previously termed "hyperplastic" polyps. METHODS: We reanalyzed data from a prospective randomized trial of an educational intervention aimed at increasing ADR...

OBJECTIVE: Endonasal resection of the pituitary embodies the minimally invasive concept. Pure endoscopic resection of pituitary adenoma has become the most popular surgical approach. Intraoperative magnetic resonance imaging (iMRI) systems have been in use for endoscopic resection of pituitary adenomas. The study aimed to evaluate the effectiveness of iMRI and neuroimaging navigation techniques during endoscopic endonasal transsphenoidal surgery of pituitary adenomas. METHODS: Data from 137 patients who underwent resection of endoscopic pituitary adenoma under 1...

Pituitary adenomas represent the third most common primary intracranial tumor in neurosurgical practice. To understand the biological behaviour of the pituitary adenomas previous studies have determined the tumor proliferation rate using monoclonal antibodies targeted against the Ki-67 antigen. The aim of this study was to correlate the Ki-67 index with hormonal profiles of pituitary adenomas. The study included 50 pituitary adenoma cases. For histopathologic evaluation, the sections were stained with routine hematoxylin and eosin method...

BACKGROUND & AIMS: Quality of endoscopists' performance of colonoscopy is measured by adenoma detection rate (ADR). Although ADR is inversely associated with interval colorectal cancer and colorectal cancer death, the effects of increasing ADR have not been demonstrated. We investigated whether increasing ADRs from individual endoscopists associates with reduced risks of interval colorectal cancer and subsequent death METHODS: We performed a prospective cohort study of individuals who underwent screening colonoscopy within the National Colorectal Cancer Screening Program in Poland, from January 1, 2004 through December 31, 2008...

BACKGROUND AND AIMS: Distal attachments placed on the colonoscope tip may positively affect performance by assisting insertion and polyp detection. The Endocuff-original appears to improve adenoma detection rate, but there are no data assessing the performance of the second generation Endocuff-vision. METHODS: A pilot service evaluation study (April-2013/September-2014) was conducted on patients with positive faecal occult blood tests within the National Bowel Cancer Programme during 3 consecutive periods: pre-cuff/no device used, during-cuff/device used and post-cuff/no device used...

BACKGROUND: The safety and diagnostic accuracy of colonoscopy depend on the quality of colon cleansing. The adenoma detection rate is usually used as a quality measurement score. OBJECTIVE: We aimed to introduce and evaluate three new parameters to determine polyps and adenomas segmental localization and their distribution in association with different bowel preparation levels during colonoscopy. We introduce the multiple adenoma detection rate (the percentage of patients with >2 adenomas diagnosed during colonoscopy), the zonal adenoma detection rate (the percentage of patients with >2 adenomas diagnosed during colonoscopy in different colon areas (rectum, sigmoid, descending, transverse, ascending and cecum colon)), and multi-zone adenoma detection rate (the percentage of patients with >2 adenomas diagnosed during colonoscopy in different colon areas with at least a segment between them with or without lesions (i...

BACKGROUND: The association between diverticulosis and colonic neoplastic lesions has been suggested, but data in literature are conflicting. This study aimed to investigate such a relationship in patients participating in a colorectal cancer screening program who underwent high-quality colonoscopy. METHODS: Data from consecutive individuals 50-75 years of age with a positive faecal immunological test were considered. Diverticulosis was categorised as present or absent...

Background and aims Colonoscopy is currently the reference method to detect colorectal neoplasia, yet some adenomas remain undetected. The water infusion technique and dying with indigo carmine has shown interesting results for reducing this miss rate. The aim of this study was to compare the adenoma detection rate (adenoma and adenocarcinoma; ADR) and the mean number of adenomas per patient (MAP) for blue-water infusion colonoscopy (BWIC) versus standard colonoscopy. Methods We performed a multicenter, randomized controlled trial in eight units, including patients with a validated indication for colonoscopy (symptoms, familial or personal history, fecal occult blood test positive)...

Endoscopy plays a major role in early recognition of cancer which is not externally accessible and therewith in increasing the survival rate. Raman spectroscopic fiber-optical approaches can help to decrease the impact on the patient, increase objectivity in tissue characterization, reduce expenses and provide a significant time advantage in endoscopy. In gastroenterology an early recognition of malign and precursor lesions is relevant. Instantaneous and precise differentiation between adenomas as precursor lesions for cancer and hyperplastic polyps on the one hand and between high and low-risk alterations on the other hand is important...

Inactivating mutations that lead to loss of heterozygosity within the HRPT2/Cdc73 gene are directly linked to the development of primary hyperparathyroidism, parathyroid adenomas, and ossifying fibromas of the jaw (HPT-JT). The protein product of the Cdc73 gene, parafibromin, is a core member of the polymerase-associated factors (PAF) complex, which coordinates epigenetic modifiers and transcriptional machinery to control gene expression. We conditionally deleted Cdc73 within mesenchymal progenitors or within mature osteoblasts and osteocytes to determine the consequences of parafibromin loss within the mesenchymal lineage...

Water exchange (WE) is a relatively new method of endoscope insertion during colonoscopy. Although its origin is rooted in the insertion phase of colonoscopy, allowing the procedure to proceed with more ease, less discomfort, and less or no sedation, its most important value may reside in the withdrawal phase. In this issue, a randomized, prospective study from China specifically designed to examine the effect of WE on adenoma detection rate (ADR) confirms previous findings: WE improves ADR. Here we discuss the trial results, the benefits of WE, and the challenges that may preclude or delay widespread WE implementation...
