Background and study aims  This is a case report on use of the CryoBalloon as a salvage technique for ablation of residual neoplasia at an endoscopic mucosal resection site. The site contained an embedded clip that could not be removed at two different sessions by three experienced endoscopists. On follow-up endoscopy, the clips and residual polyp no longer remained. The subtle scar that was present was biopsied and confirmed complete eradication of neoplasia and no polyp tissue. This case shows the potential of the CryoBalloon to ablate unwanted tissue outside of the esophagus.

Downhill esophageal varices are a rare cause of upper gastrointestinal hemorrhage. We present a case of downhill variceal bleeding due to superior vena cava thrombosis resulting from a prior central venous catheter. The patient was managed with endoscopic band ligation and later with surgical axillary vein to right atrium bypass grafting. Successful long-term resolution of varices was achieved at 1 year of follow-up. This is the longest follow-up described for combined endoscopic and surgical management in the existing literature for catheter-associated downhill varices.

Background: To evaluate resident knowledge of colorectal cancer (CRC) screening guidelines and to define areas requiring attention., Methods: A survey was created using three published guidelines for CRC screening. Program directors for internal medicine residency programs were contacted within the metro New York City area to have their residents participate., Results: Five programs participated, and 115 responses were recorded. For the appropriate testing and interval to screen for CRC, 61/115 residents identified flexible sigmoidoscopy every 5 years, 108/115 identified colonoscopy every 10 years, 16/115 identified double contrast barium enema (DCBE) every 5 years and only 12/115 thought CT-colography every 5 years was appropriate. Only 40/115 respondents appropriately identified fecal occult blood testing (FOBT) administered in the patient's home annually, while fecal immunohistochemical testing (FIT) annually at home was identified by 8/115 residents., Conclusion: While most residents seem knowledgeable regarding CRC screening with colonoscopy, many deficiencies remain. FOBT for screening purposes remains undervalued, and confusion about administering the test persists. The distinction between screening and prevention needs further reinforcement.

Background: An association of Coronary artery disease (CAD) with hepatitis C (HCV) has been suggested, but definitive data are still lacking., Aim: Our study sought to estimate the prevalence and severity of CAD in HCV patients compared to with age-, sex-, and race-matched controls without HCV infection., Subjects and Methods: 63 HCV-infected patients were compared with 63 age, race, and sex-matched controls without HCV infection undergoing coronary angiography for evaluation of CAD. CAD was defined as more than a 50% blockage in any of the proximal coronary arteries on angiogram. The severity of the stenosis was defined by the modified Reardon severity scoring system: <50% stenosis of the luminal diameter, 1 point; 50-74%, 2 points; 75-99%, 3 points; 100% or total obstruction, 4 points. The points for each lesion in the proximal coronary circulation were summed to give the score for severity., Results: A significantly higher prevalence of CAD was noted in the HCV population (69.8% vs. 47.6%, = 0.01). The combined Reardon's severity score in the HCV group was significantly higher compared to the controls (6.26 ± 5.39 vs. 2.6 ± 3.03, P < 0.0005). Additionally, significant multivessel CAD (>50% stenosis and ≥2 vessels involved) was also noted significantly more commonly in the HCV group compared to controls (57.1% vs. 15.9%, P < 0.0005)., Conclusion: In this retrospective study the prevalence and severity of CAD was higher in HCV patients who were evaluated for CAD by angiogram compared with matched non-HCV patients. HCV-positive status is potentially a risk factor for CAD.
