A 42-years-old woman had undergone operation for cholecochal cyst with gallbladder cancer 9 years ago. Pathology revealed a polypoid mass in the gallbladder with liver infiltration as poorly differentiated adenocarcinoma. Computed tomography, magnetic resonance cholangiopancreatography, and endoscopic ultrasound showed a newly developed suspected solid nodule in the peripheral portion of cystic lesion in the pancreas head. She underwent a pylorus preserving pancreaticoduodenectomy for the suspected mucinous cystic neoplasm of the pancreas. Pathology revealed poorly differentiated adenocarcinoma. The remnant choledochal cyst had developed to cholangiocarcinoma, which mimicked cystic neoplasm of the pancreas.

AbstractAbstract PDFPubReaderePub

The purpose of this study was to evaluate the efficacy and tolerability of dual therapy consisting of esomeprazole and amoxicillin as a rescue therapy for Helicobacter pylori infection.


From December 2009 to August 2010, 21 patients who experienced two consecutive eradication failures were included. They received esomeprazole (40 mg, b.i.d.) and amoxicillin (1,000 mg, b.i.d.) for 14 days as a third eradication regimen. Compliance and side effects were determined from an interview. H. pylori status was evaluated using the 13C urea breath test at least 6 weeks after treatment.


The mean age of the patients was 59 years and included 52% males. Indications for treatment were functional dyspepsia (61.9%), peptic ulcer disease (28.6%), and gastric adenoma (9.5%). H. pylori was eradicated in 14 of 21 (66.7%) patients. Minor side effects were reported in three of the 21 patients (14.3%). These side effects consisted mainly of nausea and epigastric discomfort.


A 2-week course of dual therapy failed to show satisfactory results in third-line H. pylori eradication, but it was very safe and tolerable. Therefore, dual therapy constitutes an encouraging empirical strategy for the elderly and infirm patients with multiple previous eradication failures.
