BACKGROUND Acute cholecystitis (AC) is a common emergency seen by general surgeons. Optimal treatment is laparoscopic cholecystectomy (LC); however, in cases where surgery cannot be performed due to high risk of morbidity and mortality, such as in elderly patients with comorbid diseases, other treatment modalities may be used. Percutaneous cholecystostomy (PC) is one alternative method to treat...

nowadays, tube bonding in vehicles structure is noticeably considered by many researches. in this paper, local tube compression process by a rubber ring has been studied. firstly, simulation of the process was performed by fem. then, experimental test has been carried out to validate the numerical results. numerical and experimental results were compared showing a good agreement. in the second ...

HYPOTHESIS Early laparoscopic cholecystectomy (LC) results in a shorter length of stay and acceptable conversion and complication rates when compared with antibiotic therapy plus interval LC or percutaneous cholecystostomy in patients admitted to a surgical service because of acute cholecystitis. However, actual practice does not conform to current evidence. DESIGN Retrospective cohort study....

We describe a 66-year-old man who presented initially with acute cholecystitis. He was treated by cholecystostomy and biopsy of the gallbladder mucosa which revealed carcinoma of the gallbladder. Four weeks later a cholecystectomy was performed followed by resection of the common bile duct, common hepatic duct and segments IV and V of the liver and a hepaticojejunostomy. Sixteen months later an...

chest tube (ct) or tube thoracostomy placement is often indicated following traumatic injuries. premature movement of the chest tube leads to increased hospital complications and costs for patients. placement of a chest tube is indicated in drainage of blood, bile, pus, drain air, and other fluids. although there is a general agreement for the placement of a chest tube, there is little consensu...

RATIONALE AND OBJECTIVES Percutaneous access to the renal collecting system or biliary system is most frequently performed under image guidance. However, current techniques lack a feedback mechanism to help confirm successful access. A percutaneous needle system has been developed consisting of a modified 18-gauge percutaneous access needle that measures tissue impedance at its needle tip. Init...
