AIM To investigate whether adenoma and polyp detection rates (ADR and PDR, respectively) in screening colonoscopies performed in the presence of fellows differ from those performed by attending physicians alone. METHODS We performed a retrospective review of all patients who underwent a screening colonoscopy at Grady Memorial Hospital between July 1, 2009 and June 30, 2015. Patients with a hi...

Background: Complete colonic duplication is a very rare congenital anomaly that may have different presentations according to its location and size. Complete colonic duplication can occur in 15% of gastrointestinal duplication. We report two cases of complete colonic duplications, and their characteristics. Case Presentation: We present two patients with complete colonic duplication with differ...

We present a case report of a patient with imaging findings of right colon diverticulitis that mimics colon cancer. The computed tomography showed a segment of narrowing with shoulder formation at ascending colon suggesting cancer. The colonoscopy and the follow-up imaging clarify the diagnosis of diverticulitis. We assess the value of computed tomography findings of acute diverticulitis in exc...

This case report describes the management of a frail older patient presenting with a rare case of an obstructing right-sided colonic lesion, combined with complex co-morbidities. The report briefly discusses use of colonic stenting in right colonic lesions as well as palliative management of colonic tumours in general.

BACKGROUND AND AIMS Resect and discard is a new paradigm for management of diminutive colon polyps. Little is known regarding whether patients would accept resect and discard. We surveyed colonoscopy patients and their drivers regarding acceptance of resect and discard. METHODS This was a cross-sectional survey of colonoscopy outpatients and their drivers at two outpatient academic endoscopy ...

The use of pharmaceuticals for colon cancer treatment has been increasingly personalized, in part due to the development of new molecular tools. In this review, we discuss the old and new colon cancer chemotherapeutics, and the parameters that have been shown to be predictive of efficacy and safety of these chemotherapeutics. In addition, we discuss how alternate pharmaceuticals have been devel...

a 22-year-old man presented with exertional dyspnea commencing one month prior to his admission. echocardiography revealed a non-homogenous mass, and the pathology examination of the pericardial biopsy was compatible with angiosarcoma.

The cytokinetics of a naturally occurring hyperplastic disease of the colon in mice were determined by autora diography and compared to kinetic changes seen by others in nonneoplastic and neoplastic colonic disease. Cell cycle parameters were determined using the fraction-labeled mi tosis method. Labeling index, labeling pattern, and migra tion rates were also evaluated. During colonic hyperpla...

Objective The purpose of this study was to investigate whether changes occurred in the clinical features of acute colonic diverticulitis (ACD) over a period of 10 years, to estimate the long-term probability of disease recurrence and to investigate whether it could be treated in an outpatient setting. Methods Between January 1998 and January 2009, 488 ACD patients were diagnosed and treated in ...
