BACKGROUND The objective of the present investigation was to assess the risks and benefits of pre-cutting with the needle knife at the papilla of Vater and to compare the findings with the results of classic endoscopic sphincterotomy. METHODS From January 1973 to December 1993, 2752 endoscopic cutting procedures-biliary or pancreatic sphincterotomy (EST)(More)
OBJECTIVE To implement a computer-based adverse drug reaction monitoring system and compare its results with those of stimulated spontaneous reporting, and to assess the excess lengths of stay and costs of patients with verified adverse drug reactions. DESIGN A prospective cohort study was used to assess the efficacy of computer-based monitoring, and(More)
One hundred symptomatic patients with radiolucent gallbladder stones were treated with a new piezoelectric lithotripter and oral chemolitholytic agents. Stone disintegration was achieved in 99 of these patients (99%) with a mean (+/- SD) maximum fragment size of 5.1 +/- 4.1 mm. Significant differences were found when the mean (+/- SD) fragment sizes of(More)
BACKGROUND AND STUDY AIMS The aim of the study was to investigate the evolution of endoscopic sphincterotomy (EST) over a period of 25 years at its birthplace in Erlangen, Germany. PATIENTS AND METHODS A total of 3498 consecutive ESTs between 1973 and the end of 1997 were reviewed with respect to indications, technology, success, complications, therapy of(More)
BACKGROUND Good clinical results of main pancreatic duct (MPD) stent placement in chronic pancreatitis (CP) are clouded by early stent occlusion. The aim of this study was to increase knowledge about stent occlusion and its effects on clinical symptoms, and to define criteria that enable the prediction of clogging. METHODS A total of 100 pancreatic(More)
BACKGROUND AND STUDY AIMS The aim of the present study was to analyze the risk factors associated with complications of endoscopic sphincterotomy (ES). PATIENTS AND METHODS In all consecutive endoscopic sphincterotomies carried out between September 1994 and December 1996, the possible risk factors (12 patient-related factors and 12 procedure-related(More)
BACKGROUND A critical review of the experience with extracorporeal shockwave lithotripsy (ESWL) of gallbladder stones is needed to clarify whether this method should continue to be applied to patients. METHODS Patients with symptomatic gallbladder stones were treated by piezoelectric ESWL according to a prospective protocol between 1988 and 1997. ESWL(More)
Surgical extirpation of the affected gland has been necessary for cases of sialolithiasis in which the stone cannot be removed by dilatation or dissection of the salivary duct. The ability of the piezoelectric lithotripter to deliver shockwaves to a small focus makes extracorporeal shockwave lithotripsy of salivary gland stones potentially safe. Its safety(More)
Pancreatic endotherapy is frequently performed in patients with chronic pancreatitis and stenoses of the main pancreatic duct. In a patient with long-standing chronic pancreatitis and treatment with pancreatic stents, metastatic pancreatic head carcinoma was suspected because of infiltration of the neighboring organs and hepatic lesions. Ultrasound-guided(More)
BACKGROUND Our aim was to assess the influence of the skill and experience of the endoscopist on the success and risk of endoscopic sphincterotomy techniques. METHODS The outcome of all endoscopic sphincterotomies (n = 1335) carried out between 1988 and 1995 were retrospectively analyzed with respect to the endoscopist performing the procedure.(More)
