Endoscopic biliary drainage is cheaper and provides better quality of life in patients with biliary obstruction and metastatic pancreatic cancer.

Analysis for the presence of mutant kras gene supplements conventional cytopathology for the diagnosis of PAC even without a cytopathologist in attendance and using only 3 needle passes. Among patients with negative cytopathology, the presence of kras mutation represents pancreatic cancer while the absence of kras mutation increases the possibility of benign lesion.

Tumor bleeding is the most common cause of UGIB in cancer patients. UGIB in cancer patients correlates with a high mortality rate regardless of the bleeding source. Current endoscopic treatments may not be effective in preventing rebleeding or improving survival.

The device modification for PEG using the introducer technique is feasible, safe, and efficient in outpatients with obstructive head and neck cancer. In this series, it allowed the use of a larger-caliber tube with low complication rates and no procedure-related mortality.

Endoscopic application of SurgiSIS-an acellular fibrogenic matrix--is safe and effective for the treatment of gastrocutaneous fistula after RYGB.

AIM:To compare band ligation (BL) with endoscopic sclerotherapy (SCL) in patients admitted to an emergency unit for esophageal variceal rupture. METHODS:A prospective, randomized, single-center study without crossover was conducted. After endoscopic diagnosis of esophageal variceal rupture, patients were randomized into groups for SCL or BL treatment. Sclerotherapy was performed by ethanolamine oleate intravascular injection both above and below the rupture point, with a maximum volume of 20 mL. For BL patients, banding at the rupture point was attempted, followed by ligation of all variceal tissue of the distal esophagus. Primary outcomes for both groups were initial failure of bleeding control (5 d), early re-bleeding (5 d to 6 wk), and complications, including mortality. From May 2005 to May 2007, 100 patients with variceal bleeding were enrolled in the study: 50 SCL and 50 BL patients. No differences between groups were observed across gender, age, ChildPugh status, presence of shock at admission, mean hemoglobin levels, and variceal size. RESULTS:No differences were found between groups for bleeding control, early re-bleeding rates, complications, or mortality. After 6 wk, 36 (80%) SCL and 33 (77 %) EBL patients were alive and free of bleeding. A statistically significant association between Child-Pugh status and mortality was found, with 16% mortality in Child A and B patients and 84% mortality in Child C patients (P <0.001). CONCLUSION:Despite the limited number of patients included, our results suggest that SCL and BL are equally efficient for the control of acute variceal bleeding.

Double-balloon enteroscopy (DBE) is a useful method for endoscopic retrograde cholangiopancreatography (ERCP) in patients with Roux-en-Y anatomy. Depending on the distorted anatomy, endoscopic therapies with conventional scopes were very difficult or impossible before the advent of DBE and patients had to be submitted to a percutaneous or surgical approach. The case of 6 patients with different types of Roux-en-Y-altered anatomy in which DBE-ERCP was performed with 83.3% successful rate (5/6) is reported confirming recent data in the literature on the feasibility of this method.
