TurkeyHydatid disease is a zoonosis caused by the larvae of Echinococcus granulosus. Humans are an intermediate host and are usually infected by direct contact with dogs or indirectly by contaminated foods. Hydatid disease mainly involves the liver and lungs. The disease can be asymptomatic. Imaging techniques such as ultrasonography and computed tomography are used for diagnosis. The growth of hydatid cysts can lead to complications. Communication between bile duct and cysts is a common complication. The goal of treatment for hydatid disease is to eliminate the parasite with minimum morbidity and mortality. There are 3 treatment options: surgery, chemotherapy, and interventional procedures. Medical treatment has low cure and high recurrence rates. Percutaneous treatment can be performed in select cases. There are many surgical approaches for managing hydatid cysts, although there is no best surgical technique, and conservative and radical procedures are used. Conservative procedures are usually preferred in endemic areas and are easy to perform but are associated with high morbidity and recurrence rates. In these procedures, the parasite is sterilized using a scolicidal agent, and the cyst is evacuated. Radical procedures include hepatic resections and pericystectomy, which have high intraoperative risk and low recurrence rates. Radical procedures should be performed in hepatobiliary centers. The most common postoperative complications are biliary fistulas and cavityrelated complications. Endoscopic retrograde cholangiopancreatography can be used to diagnose and treat biliary system complications. Endoscopic sphincterotomy, biliary stenting, and nasobiliary tube drainage are effective for treating postoperative biliary fistulas.

This study shows that 14% of malignant liver tumors will develop LR within a year after LRFA. Additional 4% of the lesions will demonstrate recurrence within 1 cm of the ablation zone, mostly as part of a multifocal recurrence. Ablation margin is the only parameter that the surgeon can manipulate to decrease LR.

Infundibular stenosis may develop secondary to ventricular septal defect, and transannular patch plasty can affect mortality and morbidity rates. Therefore, dextroposition of the aorta has been investigated in order to eliminate discrepancies in the literature. Figures and illustrations from the selected references have been investigated and "actual dextroposition of the aorta" has been evaluated as far as the aorta is visible. A careful examination of these figures revealed the following tips and pearls for accurate diagnosis of dextroposition of the aorta: Aorta and ventricular septal defect should be adjacent for a "true" dextroposition of the aorta; the plane where the aorta exits from the ventricle should penetrate the plane of the ventricular septal defect towards the right ventricle; if the aorta and ventricular septal defect intersect at one edge, the aorta may seem to be dextroposed; new diagnostic modalities are necessary to evaluate the actual dextroposition status of the aorta for the proper planning of treatment.
