In this prospective study, magnetic resonance (MR) imaging was used to localize gastrinoma in 24 patients with Zollinger-Ellison syndrome. The results were confirmed by means of either surgery or percutaneous liver biopsy and compared with results of computed tomographic (CT) scanning, selective abdominal angiography, and abdominal ultrasound (US). For(More)
STUDY OBJECTIVE To evaluate criteria of positivity for and usefulness of both the secretin and calcium gastrin-provocative tests in patients with the Zollinger-Ellison syndrome. DESIGN Prospective trial in consecutive patients. SETTING Referrals to a clinical research center. PATIENTS Consecutive sample of 80 patients with the Zollinger-Ellison(More)
The ability of operative endoscopic transillumination of the bowel wall to detect duodenal gastrinoma was evaluated prospectively in 26 patients with the Zollinger-Ellison syndrome. The results were assessed by exploratory laparotomy and compared with the results of other localization techniques. Twelve duodenal gastrinomas were resected from 10 patients.(More)
To determine the ability of selective abdominal angiography to localize gastrinoma in patients with Zollinger-Ellison syndrome, selective angiography was performed in 70 consecutive patients and the results were assessed prospectively by either surgery, autopsy, or percutaneous biopsy. In addition, to define the role of angiography in the management of(More)
The prevalence of recurrent Clostridium difficile infection (RCDI) is increasing; fecal microbiota transplantation (FMT) is an effective therapy. However, there have been no studies of the efficacy of a single session of combined enteral and colonic FMT or characterizations of changes in the microbiota between donors and recipients. We performed a study of(More)
To determine the long-term efficacy, safety, and toxicity of omeprazole, we studied 40 patients with Zollinger-Ellison syndrome given omeprazole for 6-51 mo (median 29). The mean daily dose of omeprazole required to control gastric acid secretion was 82 +/- 31 mg. Thirty-one patients required omeprazole once per day. In 9 patients acid output was not(More)
We examined prospectively the criteria for medical management in 16 patients with Zollinger-Ellison syndrome who had had previous gastric surgery. Each patient received sufficient antisecretory medication to lower gastric acid output to less than 10 mEq/h during the last hour before the next dose of drug. The 7 patients with a vagotomy but no gastric(More)
Twenty patients with Zollinger-Ellison syndrome who were undergoing surgery were studied prospectively to assess the efficacy and safety of IV omeprazole. During the preoperative period, in 19 of 20 patients, omeprazole 60 mg administered as an IV bolus every 12 hours inhibited acid output to less than 5 mEq/h measured in the last hour before the next dose(More)
The incidence of ulcers of the stomach and duodenum and their response to medical therapy, in patients with Zollinger-Ellison syndrome is well described. However, reflux esophagitis is less well recognized. In this study we determined the frequency of reflux esophagitis in 122 patients with Zollinger-Ellison syndrome and examined their response to medical(More)
The current standard of care for hepatitis C infection is peginterferon/ribavirin (PegIFN/RBV). We are entering the era where direct-acting antiviral agents (DAAs) will be added to PegIFN/RBV, leading to higher sustained response rates in genotype 1 infected individuals. Currently DAAs are directed toward specific proteins involved in hepatitis C(More)
