To study the efficacy of extracorporeal shock-wave lithotripsy (ESWL) of pancreatic duct stones, seventeen patients (mean age: 42 years) with recurrent attacks of abdominal pain as a result of chronic calcifying pancreatitis were treated with this method. In all cases, endoscopic removal of the stones proved impossible. When there was fragmentation, the(More)
Chronic calcifying pancreatitis presents a major clinical problem, often requiring extensive surgery. Extracorporeal shock wave lithotripsy (ESWL) offers a new therapeutic option. We applied ESWL after endoscopic sphincterotomy of the pancreatic orifice in eight patients with impacted pancreatic duct stones. An electromagnetic lithotriptor (Siemens(More)
OBJECTIVES We performed a randomized study that compared extracorporeal shock wave lithotripsy (ESWL) with conventional cholecystectomy for uncomplicated symptomatic gallstones. The primary outcome of the study was the influence of therapy on biliary colic and gastrointestinal symptoms. METHODS In the period October 1989-March 1992, 26 patients were(More)
PURPOSE Both "high tie" (HT) and "low tie" (LT) are well-known strategies in rectal surgery. The aim of this study was to compare colonic perfusion after HT to colonic perfusion after LT. METHODS Patients undergoing rectal resection for malignancy were included. Colonic perfusion was measured with laser Doppler flowmetry, immediately after laparotomy on(More)
Shortly after extracorporeal shock wave lithotripsy (ESWL) was introduced as a promising new treatment modality for gallstone disease, a randomized controlled study was performed to assess the cost-effectiveness of ESWL compared to open cholecystectomy, the gold standard. During the performance of this study it was found that during a 3-year intake period(More)
Extracorporeal shock wave lithotripsy (ESWL) is a new treatment modality for retained common bile duct stones. Sixty-two patients (mean age 75 years, range 27-95 years) with retained common bile duct stones were treated with two different lithotriptors. One of the lithotriptors operated on the electrohydraulic principle (Dornier HM-3) (n = 13), the other on(More)
OBJECTIVE Determination of the efficacy of extracorporeal shock wave lithotripsy (ESWL) of gallbladder stones and adjuvant treatment with oral bile acids. SETTING Department of Surgery, University Hospital Dijkzigt, Rotterdam, the Netherlands. DESIGN Descriptive clinical research. PATIENTS AND METHODS In 4 years, 133 patients (34 males and 99 females,(More)
To establish the value of ultrasound (US) in the follow-up of patients treated with extracorporeal shockwave lithotripsy (ESWL), the results of 484 US examinations of 87 patients were analyzed and related to the results of ESWL. Reliability of US in assessing efficacy was investigated by comparing consecutive US examinations. Unreliable US results were(More)
From April 1988 till May 1990 54 patients with symptomatic gallbladder stones were treated in the University Hospital Rotterdam-Dijkzigt with extracorporeal shock wave lithotripsy (ESWL) followed by oral administration of bile acids (urso- and chenodeoxycholic acid). These patients on average underwent 2 sessions of ESWL with an electromagnetic lithotriptor(More)
Extracorporeal shock wave lithotripsy (ESWL) was introduced as a nonsurgical treatment for uncomplicated, symptomatic gallstone disease. Due to its limited results and the possibility of stone recurrence, ESWL is mainly indicated for patients who reject or cannot tolerate cholecystectomy. For budgetary and planning purposes, it is essential to know what(More)
