BackgroundAdhesions in acute cholecystitis tax even the more experienced operator during laparoscopic cholecystectomy. Blunt and sharp dissection, electrocautery, laser, hydrodissection, and ultrasonic dissection may all have their limitations. Thus there is a need for an alternative and more effective method.MethodLaparoscopic cholecystectomy was carried out in 281 patients with acute cholecystitis. ...

BACKGROUND: Patients with spinal cord injury (SCI) have increased prevalences of gallstones and acute acalculous cholecystitis. A possible explanation for the increased prevalence of gallstone disease in SCI patients is decreased gallbladder motility causing gallbladder stasis, a known risk factor for gallstone disease. We investigated gallbladder function in SCI. METHODS: ...

BACKGROUND: Duodenal diverticula are acquired lesions found more often in older patients; when located near the major duodenal papilla they are called juxtapapillary. The prevalence of juxtapapillary duodenal diverticula (JDD) in the general population is around 20%; they are often associated with biliary lithiasis. This study assessed the association between ...

Our objective was to compare the effectiveness of percutaneous cholecystostomy (PC) vs conservative treatment (CO) in high-risk patients with acute cholecystitis. The study was randomized and comprised 123 high-risk patients with acute cholecystitis. All patients fulfilled the ultrasonographic criteria of acute inflammation and had an APACHE II score > or ...
Quallich Leonard G - - 2002
BACKGROUND: Microlithiasis has been proposed as a cause of both occult gallbladder disease and of idiopathic pancreatitis. Theoretically, microlithiasis could also cause postcholecystectomy pain by causing temporary biliary obstruction and may be more common in patients with sphincter of Oddi dysfunction. The frequency of crystals in bile duct aspirates was ...

OBJECTIVES: Uric acid stones are best managed by chemolysis. Some patients with acutely symptomatic stones opt for endourologic therapies. The radiolucent nature of these stones makes secondary interventions difficult to plan. Computed tomography becomes the modality of choice to identify stone locations and size in these patients. We analyzed patients ...

Acute acalculous cholecystitis remains a diagnostic challenge in critically ill trauma patients. Laboratory studies are nonspecific and associated injuries or mental status changes may mask clinical signs and symptoms. We conducted a retrospective study to assess the utility of ultrasound in the diagnosis of acute acalculous cholecystitis. We hypothesized that ...

BACKGROUND: There is a well established relationship between primary hyperparathyroidism and recurrent calcium-containing calculi. Traditionally, the diagnosis is confirmed by the presence of elevated intact parathyroid hormone (iPTH) and serum ionised calcium levels. The prevalence and role of elevated iPTH in the presence of normocalcemia in patients with renal stone ...
