BACKGROUND & AIMS An attenuated form of familial adenomatous polyposis has been described, but the phenotype remains poorly understood. METHODS We performed genetic testing on 810 individuals from 2 attenuated familial adenomatous polyposis kindreds harboring an identical germline adenomatous polyposis coli gene mutation. Colonoscopy was performed on mutation-positive persons. RESULTS The d...
Low folate status is a risk factor for colon carcinogenesis; mechanisms proposed to account for this relationship include uracil misincorporation into DNA and global DNA hypomethylation. We investigated whether such biomarkers are related to folate status in isolated colonocytes from colonoscopy patients. In cases with adenomatous polyps (n = 40) or hyperplastic polyps (n = 16), colonocytes wer...
INTRODUCTION Gastrointestinal lipomas, though rare are the second most common benign tumors of the colon after adenomatous polyps. The diagnosis is difficult and is often mistaken for adenomatous polyp or cancer (1). Management of incidentally detected asymptomatic large colon lipomas has not been well studied. To our knowledge, this is the first case report of asymptomatic colon lipoma that wa...
Histological sections of adenomatous polyps of the colon showing carcinoma were studied by video image analysis. Nuclear DNA content and morphology were measured in regions identified as either dysplasia, carcinoma confined to the mucosa, or carcinoma invading the muscularis mucosa. Where carcinoma was present, areas of dysplasia in the same polyp were found to have similar distributions of nuc...
We present a rare case of a benign fibroepithelial polyp of the renal pelvis in a patient with familial adenomatous polyposis. In our paper we describe a new minimally invasive technique developed in our unit using an amplatz goose neck snare via a percutaneous nephroscope sheath in the management of the benign fibroepithelial polyp of the renal pelvis and present a current review of management...
BACKGROUND/AIMS A flexible spectral imaging color enhancement system was installed in new capsule software for video capsule endoscopy. Contrast image capsule endoscopy (CICE) is a novel technology using light-emitting diodes selected for the main absorption range of hemoglobin. We assessed the feasibility and diagnostic effi cacy for small bowel surveillance in patients with polyposis syndrome...
