PURPOSE In recent years, the incidence of early-stage colorectal cancer (CRC) has markedly increased in the population within the Republic of Korea. The aim of this study was to evaluate the clinicopathologic features of adenomatous polyps in TNM stage I CRC patients and in the general population. METHODS Between March 2003 and September 2009, 168 patients with stage I CRC were enrolled in th...

BACKGROUND & AIMS The sensitivity of computed tomographic (CT) virtual colonoscopy (CT colonography) for detecting polyps varies widely in recently reported large clinical trials. Our objective was to determine whether a computer program is as sensitive as optical colonoscopy for the detection of adenomatous colonic polyps on CT virtual colonoscopy. METHODS The data set was a cohort of 1186 s...

BACKGROUND Flexible sigmoidoscopy (FS) is a safe and effective method for colorectal cancer (CRC) screening. Several studies have demonstrated that individuals who have undergone surgery are at a greater risk of having incomplete FS. This study explored predictors of incomplete FS and reduced polyp detection rates for participants who had undergone abdominal or pelvic surgery. METHODS From Ja...

py for the investigation of lower abdominal pain. Colonoscopy showed a whitish, flat, elevated polyp, 10mm in diameter, in the ascending colon (l" Fig. 1). Endoscopic mucosal resection (EMR) was carried out, and the resected specimen histologically revealed both invasive cancer and serrated adenomatous glands coexisting in an inverted hyperplastic polyp (IHP) (l" Fig. 2a–c). A follow-up colonos...

Polypoid lesions of the gallbladder in children are rare. We report a case of a gallbladder polyp in a 14-year-old boy who presented with recurrent right upper quadrant abdominal pain. Ultrasound examination of the abdomen revealed a polypoid lesion of the gallbladder. His symptoms resolved after laparoscopic cholecystectomy. Histological examination of the gallbladder demonstrated a benign ade...

Meckel's diverticulum which has been involved in an intussusception. Polyps Painless bleeding suggests a solitary rectal polyp. These are almost always not adenomatous. The bleeding, separate from the stool and of moderate quantity, necessitates sigmoidoscopy and snaring of the polyp. Such polyps should be sent for histological examination to check that they are not premalignant. Multiple polyp...

BACKGROUND To investigate the prevalence and risk factors of asymptomatic colorectal diverticulosis in Taiwanese general population. METHODS From January 2009 to December 2011, consecutive asymptomatic subjects undergoing a health check-up were evaluated by colonoscopy. The colorectal diverticulosis was assessed, and a medical history and demographic data were obtained from each subject. Logi...

OBJECTIVE To describe the implementation of a formal single-operator led endoscopic mucosal resection (EMR) service in a district general hospital, and the effect on patient outcome of this service development. DESIGN Prospective audit during initiation and subsequent development of EMR service. SETTING District general hospital. PATIENTS All patients referred to EMR service between 1 Jan...

The authors evaluated alcohol drinking and cigarette smoking in relation to risk of colorectal polyps in a Nashville, Tennessee, colonoscopy-based case-control study. In 2003-2005, cases with adenomatous polyps only (n = 639), hyperplastic polyps only (n = 294), and both types of polyps (n = 235) were compared with 1,773 polyp-free controls. Unordered polytomous logistic regression was used to ...
