Left pulmonary artery sling (LPAS) is a rare congenital anomaly in which the left pulmonary artery originates from the posterior aspect of the right pulmonary artery and courses between the trachea and esophagus to reach the left lung. This anomaly causes distal tracheal and/or right main-stem bronchus compression.

Solid pseudopapillary tumors (SPTs) of the pancreas is a low-grade malignant tumor, accounting for only 1–2.5% of all pancreatic tumors. In particular, small (≤ 3 cm) SPTs do not often have typical computed tomography (CT) features, making them easily misdiagnosed with other solid tumors and eventually affecting the choice of treatment method.

Calculating intra-aneurysm flow uses optical flow with computational fluid dynamics simulation on the numerical analysis. This is a new method to better understand the intravascular flow and aneurysm flow as well as factors related to the inflow vortex and the inflow jet which increase the rupture risk in patients with an aneurysm.

Laparoscopic adrenalectomy has emerged as the standard treatment for adrenal tumors. Although the application of high - resolution cameras has enhanced visualization in conventional two - dimensional laparoscopy, it has not fully overcome the limitations of depth perception and spatial recognition. This study aims to evaluate the outcome of three - dimensional laparoscopic adrenalectomy.
