BACKGROUND AND AIMS Gastrin and the cholecystokinin type B/gastrin receptor (CCKBR) have been shown to be expressed in colorectal adenocarcinoma. Both exogenous and autocrine gastrin have been demonstrated to stimulate growth of colorectal cancer but it is not known if gastrin affects the growth of colonic polyps. The purpose of this study was to determine if gastrin and CCKBR are expressed in ...

Objective Endometrial polyps are localised growths of endometrial tissue containing glands, stroma and blood vessels, covered with epithelium. The reported prevalence of endometrial polyps is dependent upon the population being studied and the uterine imaging technique utilised. The light microscopy literature provides very little information regarding their microvasculature and lymphatic syste...

BACKGROUND/AIMS Gallbladder polyps and colorectal adenomas share many common risk factors; however, their association has never been studied. The aim of this study was to investigate this association in asymptomatic healthy subjects. METHODS Consecutive asymptomatic subjects who underwent both screening colonoscopy and abdominal ultrasonography at Kyung Hee University Hospital in Gang Dong be...

Colorectal polyps are precursor lesions of colorectal cancer; hence, early detection and dysplasia grading essential for determining cancer risk, the possibility developing subsequent polyps, follow-up recommendations. The significant contribution this study is development an enhanced deep-learning model called Fast Fourier Convolutional ResNet (FFC-ResNet) to classify grades polyps. It based o...

The most frequently occurring lesions in the colon are the hyperplastic polyps. Hyperplastic polyps have long been considered as lesions with no malignant potential and colonoscopy for these patients is not recommended. However, recent works suggest that hyperplastic polyps may represent precursor lesions of some sporadic colorectal cancers. Until now, no biomarker allows to identify the subset...

Background and study aims  The majority of polyps removed at colonoscopy are diminutive (≤ 5 mm) to small (< 10 mm) and there are few guidelines for the best way for these polyps to be removed. We aimed to assess the feasibility and effectiveness of cold biopsy forceps polypectomy with pre-lift (CBPP) for polyps ≤ 7 mm. Our aims were to assess completeness of histological resection of this tech...

BACKGROUND Nasal polyposis is a common problem in the eastern province of Saudi Arabia. Since allergic fungal sinusitis (AFS) can present with unilateral or bilateral nasal polyps, it is important to be aware of the prevalence of AFS in patients with nasal polyps. PATIENTS AND METHODS The medical records of 91 patients with nasal polyps admitted for functional endoscopic sinus surgery were re...

XB Serrated colon polyps are a group of heterogeneous lesions characterized histologically by glandular serration (ie, a saw-toothed folding of colonic crypt epithelium). The World Health Organization has classified serrated lesions into 3 general categories (Table). Historically, serrated polyps were called hyperplastic polyps (HPs) and were thought to have no malignant potential. However, rec...

Colorectal adenomas and possibly some hyperplastic polyps are precursors of colorectal cancer. Tobacco use is associated in epidemiologic studies with these polyps, although links between smoking and colorectal cancer are less consistent. To characterize the role of tobacco in early colorectal carcinogenesis, we compared tobacco use among 4,383 subjects with histologically verified benign (hype...
