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)...

BACKGROUND In patients with large colon polyps, late-onset bleeding may be more likely to occur because of the larger cutting surface. In these patients, hemostatic agents may be applied to prevent the late-onset bleeding. A total of 7 patients developed hypofibrinogenemia caused by hemocoagulase following excision of colon polyps in our center from November to December 2015. CASE REPORT Seven patients underwent excision of colon polyps in our center from November to December 2015. The cutting face was large in these patients after surgery; therefore, hemocoagulase was used to prevent potential late-onset bleeding...

Evidence suggests that up to one fifth of colorectal carcinomas (CRC) develop from serrated polyps, named for their pattern of colonic crypts, and include the sessile serrated adenoma/polyp (SSA/P) that has malignant potential. SSA/Ps are typically located in the proximal colon and have molecular features of hypermethylation of CpG islands in gene promoters and activating point mutations (V600E) in the BRAF oncogene. Both of these features are seen in sporadic CRCs with microsatellite instability (MSI) which is potentially consistent with an origin of these cancers from precursor SSA/Ps...

REVIEW
Ryan K Schmocker, Anne O Lidor
Benign gastric lesions represent various pathologic entities and management considerations. Upper endoscopy serves as the primary diagnostic modality for gastric lesions. Persistent or giant gastric ulcers represent unique subtypes of ulcers, requiring investigation of the underlying cause. Medical management remains the mainstay of treatment; however, indications for surgical intervention remain. Gastric polyps also represent diverse etiologies, and accurate diagnosis requires pertinent information and tissue samples...

Early gastric cancer (ECG) can be difficult to diagnose endoscopically. Endoscopists should be familiar with subtle changes and endoscopic features of EGC. Chromoendoscopy and image-enhanced endoscopy improve diagnostic accuracy and facilitate endoscopic resection. Endoscopic submucosal dissection is a preferred endoscopic technique for resection of EGC and offers a comparable overall survival to surgical resection. Endoscopic management of benign gastric epithelial polyps (fundic gland polyps, hyperplastic polyps, and gastric adenoma) depends on patient symptomatology, patient's comorbidities (eg, familial syndromes), lesions' characteristics, and risk of malignant transformation...

Colorectal cancer (CRC) is the third leading causes of cancer mortality, and the early-stage detection could significantly enhance survival rates. Cancer influences the important metabolic pathways and the changes in metabolite levels had been used in many studies as the potential biomarkers. This study is aimed at screening metabolite biomarkers with CRC diagnosis potentials. The direct infusion mass spectrometry (MS) metabolomic analysis based on dried blood spot was used to distinguish CRC from polyp. The target metabolites were composed of 23 amino acids and 26 acylcarnitines...

The gallbladder polyps are a common finding during ultrasonography but only in rare cases they may be a cancer. When a polyp is greater than 1 cm, the cholecystectomy is usually performed. In these images, a polyp of 4 cm corresponding to a collection of mucus (mucocele) is reported. This unusual polyp of the gallbladder was caused by heterotopic intestinal mucosa.

Interval colorectal cancer (I-CRC) is defined as a CRC diagnosed within 60 months after a negative colonoscopy, taking into account that 5 years is the "mean sojourn time." It is important to prevent the development of interval cancer. The development of interval colon cancer is associated with female sex, old age, family history of CRC, comorbidities, diverticulosis, and the skill of the endoscopist. During carcinogenesis, sessile serrated adenomas/polyps (SSA/Ps) share many genomic and colonic site characteristics with I-CRCs...

Colonoscopy and endoscopic removal of precancerous polyps play an important role in colorectal cancer (CRC) prevention. Improved endoscopes and quality standards have led to an increasing polyp and adenoma detection rate. Optimal polyp resection techniques and management strategies are key for an effective colonoscopy practice. Areas covered: Strategies for how to improve diminutive polyp (polyps up to 5mm in size) management are discussed because of their high prevalence. Systematic removal of diminutive polyps leads to increasing costs of colonoscopy practice, while the effect on colorectal cancer prevention might be negligible...

BACKGROUND: Decreased expression of airway epithelial-specific transcription factor NK2 homeobox 1 (NKX2-1) was associated with allergic inflammation in asthma patients. However, the expression and role of NKX2-1 in nasal polyps (NPs) with different endotypes were undefined yet. METHODS: We examined the expression of key cytokines (interleukin [IL]-4 IL-5, IL-13, and IL-17A, etc.) and NKX2-1 in NPs with different endotypes and control tissues by immunohistochemistry staining, qualitative polymerase chain reaction (qPCR), enzyme-linked immunosorbent assay (ELISA), and Western blot analysis...

BACKGROUND: Cap-assisted colonoscopy (CAC) has been reported to increase the adenoma detection rate (ADR) in Asian population. However, CAC trials in non-Asian population have had conflicting results. Studies in North America have shown an improvement in ADRs with the use of CAC, but it mainly included white and African American patients. Given the lack of prospective studies of CAC in Hispanics, we conducted this randomized controlled trial. MATERIALS AND METHODS: This is a randomized controlled trial comparing CAC with standard colonoscopy (SC) in patients undergoing screening or surveillance colonoscopy...

Laterally spreading tumors (LSTs) are generally defined as superficial lesions ≥10 mm in diameter that typically extend laterally rather than vertically along the colonic wall. Such lesions are now increasingly reported because of increased awareness and the introduction of chromo and magnifying colonoscopy. Although the clinicopathological characteristics and the efficacy of endoscopic management of LSTs have been defined in Japanese cohorts, reports from the Middle East are lacking where surgical resection is the mainstay of treatment...
