After removal of the gallbladder, pain may persist in some patients. To study this condition, 124 patients from two randomized trials, including those with symptomatic noncomplicated gallbladder stones (n = 90) and acute cholecystitis (n =34), were interviewed, while 139 patients (90%) excluded from both trials responded to a questionnaire 5 years after the(More)
BACKGROUND Cholecystectomy is routinely recommended to prevent recurrent disease after an initial episode of acute cholecystitis. Therefore, randomized controlled trials have mainly focused on the timing of surgery, but many patients scheduled for cholecystectomy have deferred surgery with long periods of symptom-free intervals. Our present aim is to(More)
BACKGROUND/AIMS Cholecystectomy is considered the treatment of choice for symptomatic gallstone disease. Some patients abstain from surgery and provide the opportunity to study the natural history of cholelithiasis. The aim of the present study was to examine the feasibility and safety of observation after extended long-term follow-up in a randomized(More)
OBJECTIVE To investigate whether enhanced neuroproliferation could be involved in the pathogenesis of gallstone pain. MATERIAL AND METHODS Gallbladders from 117 patients with gallstones and 43 controls were examined. The gallbladder samples were immunostained against the pan-neuronal marker PGP 9.5 and the number of nerves and nerve area per tissue area(More)
OBJECTIVE The cardinal indication for surgical treatment of gallstones is pain attacks. However, following cholecystectomy, 20% of patients remain symptomatic. It is unclear to what extent post-cholecystectomy symptoms can be ascribed to persistence of preoperative symptoms or to new pathology. The pain and digestive pattern in gallstone patients has not(More)
AIM The aim of our study was to examine gastric function, gallbladder emptying, and dyspepsia in symptomatic gallbladder stone patients (SGBS) to see if a motility disorder, expressed by gastric function and gallbladder emptying, may cause dyspepsia in SBGS. MATERIALS AND METHODS Gastric function and gallbladder emptying in 21 SGBS referred for surgical(More)
