Predictors of suboptimal bowel preparation in asymptomatic patients undergoing average-risk screening colonoscopy.

Aim: To identify risk factors for a suboptimal preparation among a population undergoing screening or surveillance colonoscopy.

Methods: Retrospective review of the University of Michigan and Veteran's Administration (VA) Hospital records from 2009 to identify patients age 50 and older who underwent screening or surveillance procedure and had resection of polyps less than 1 cm in size and no more than 2 polyps. Patients with inflammatory bowel disease or a family history of colorectal cancer were excluded.

The impact of fair colonoscopy preparation on colonoscopy use and adenoma miss rates in patients undergoing outpatient colonoscopy.

Background: The impact of fair bowel preparation on endoscopists' recommendations and adenoma miss rates in average-risk patients undergoing colonoscopy is unknown.

Objective: To assess the impact of fair bowel preparation on endoscopists' interval colonoscopy recommendations and miss rates in colonoscopies performed within 3 years of the index colonoscopy in average-risk patients undergoing colorectal cancer screening.

Design: Retrospective chart review.

Syndromic incidence of ovarian carcinoma after liver transplantation, with special reference to anteceding breast cancer.

Ovarian cancer is the gynecologic malignancy with the highest number of deaths in the United States. Previous studies had found a decreased incidence of female gynecological malignancies after liver transplantation. In order to estimate the incidence of ovarian carcinoma after liver transplantation, we evaluated 1708 consecutive liver transplant recipients from 1984 to 2001.

Thrombendvenectomy for organized portal vein thrombosis at the time of liver transplantation.

Objective: To determine the efficacy of portal thrombendvenectomy in cases of portal vein thrombosis at the time of orthotopic liver transplantation.

Summary Background Data: Portal vein thrombosis (PVT) has been reported to have an incidence of 2% to 39% in end-stage liver disease. Multiple techniques have been suggested to treat this finding.
