Laparoscopic cholecystectomy can be subject to complications such as bile duct injury, which seriously harm the patient or even result in death. Computer-assisted interventions have potential prevent by highlighting critical structures (cystic and cystic artery) during surgery, helping surgeon establish Critical View of Safety avoid structure misidentification.

introduction: natural killer (nk) cells, of which cd56 is a specific marker, play an important role in host defense against tumors. cancer stem cells, of which aldehyde dehydrogenase isoform 1 (aldh1) is an immunohistochemical marker, are a group of tumorigenic cells which are involved in migration and tumor recurrences. we aimed to evaluate the expression of aldh1 and cd56 in common salivary g...

mirizzi’s syndrome is a rare complication of gallstone disease , that gallbladder lumen can lie alongside the common hepatic duct, resulting in inflamation and resultan bile duct stricture . most cases are not indentified preoperatively. variations of the cystic duct and its point of :union: with the common hepatic duct are surgically important . here, we present an unusual case of type i miriz...

Congenital cystic lesions of the pancreas are rare findings. Furthermore, dermoid cyst of the pancreas is exceptionally uncommon. A review of the world literature showed that only 18 documented cases of dermoid cyst of the pancreas were reported so far. The pre-operative evaluation of this lesion is rather questionable, with definitive diagnosis taking place intra-operatively. Herein, we presen...
