Low Progression Rate in Surveilled Side-Branch Intraductal Pancreatic Mucinous Neoplasms

Side-branch intraductal papillary mucinous neoplasms (sb-ipmns) have a low rate (15.3%) of clinically relevant progression (CR-progression), leading to invasive cancer mainly due to size increase or main-duct involvement. Patients with CR-progression benefit from timely resection, but initial size alone is not a reliable indicator for surgery. Non-operative surveillance is crucial, as most surveilled lesions show low-grade pathology and cancer development in the pancreas is rare.

Robotic liver resection with short-pitch dividing shortens hospital stay

Robotic liver resection using a close-to-open forceps technique was associated with no bile leakage and a shorter hospital stay than laparoscopic resection, even though more complex resections were performed in the robotic group.

Robotic bile duct stone surgery: fewer complications

Removing large common bile duct stones with a robot rather than laparoscopically was linked to fewer complications and shorter hospital stays, at a higher cost, in a study from one Chinese hospital.
