AIM OF THE STUDY It is estimated that between 15% and 35% of sporadic colorectal cancers (CRC) developing from adenomas come from serrated polyps. Currently, the most effective method used to prevent CRC is the removal of adenomas, including serrated polyps, during colonoscopy. The aim of this paper is to analyze the changes characterized as serrated polyps and detected during screening colonos...

PURPOSE To delineate the relationship between the optic nerves and the posterior paranasal sinuses using CT data. METHODS Direct coronal sinus CT scans of 150 consecutive patients with chronic inflammatory sinus disease were reviewed by two radiologists. Axial oblique reconstructions along the course of the optic nerve were obtained for the first 100 patients. The direct relationship between ...

BACKGROUND Primary small cell neuroendocrine carcinoma (SNEC) of paranasal sinuses is an extremely rare malignant tumor known for its aggressive clinical behavior. METHODS Nineteen patients with SNEC in paranasal sinuses by magnetic resonance imaging (MRI) (n = 19) and computerized tomography (CT) and MRI (n = 18) were retrospectively studied. CT and MRI were undertaken to investigate tumor f...

INTRODUCTION The aim of this study was to determine which technique of uncinectomy, classical or swing door technique. MATERIALS AND METHODS Four hundred eighty Cases of sinusitis were selected and operated for Functional Endoscopic Sinus Surgery (FESS). Out of these, in 240 uncinectomies classical uncinectomy was done whereas in another 240 uncinectomies swing door technique was used. Initia...

OBJECTIVE The aim of the study was to investigate the prevalence of endometrial polyps in patients with uterine fibroids and associated factors of coexistence of these two pathologies. MATERIALS AND METHODS The medical records of 772 patients who underwent hysterectomy because of uterine fibroids were retrospectively reviewed. Patients were divided into two groups according to the presence of...

BACKGROUND/AIMS The frequency of gastric polyps increases with the widespread use of endoscopy for diagnosis and treatment. As gastric polyps can be malignant or premalignant, histopathological evaluation is needed. The aim of this study is to determine the prevalence and characteristics of gastric polyps in patients undergoing endoscopy. MATERIALS AND METHODS This study consisted of a retros...

Detection and complete removal of precancerous neoplastic polyps are central to effective colorectal cancer screening. The prevalence of neoplastic polyps in the screening population in the United States is likely >50%. However, most persons with neoplastic polyps are never destined to develop cancer, and do not benefit for finding and removing polyps, and may only be harmed by the procedure. F...
