In an attempt to clearly separate benign from malignant mucinous papillary tumors of the pancreas, Kawai et al have, in a small series, suggested that tumor size larger than 30 mm, mural nodules larger than 5 mm, and carcinoembryonic antigen levels higher than 110 ng/mL in pure pancreatic juice were predictive of malignant factors. How to perform the latter test effectively is a problem requiring further study.
Augmented reality in surgery is a new approach in executing detailed surgical operations. It requires low-performance surgical dexterity and is currently used as an effective teaching tool for training residents. Further, this entity may create new modes of diagnosis and treatment of technically challenging patients. Very experienced surgeons can extend the limits of a safe area to allow more complete and radical operative therapy, whereas younger surgeons may benefit by being oriented to critical anatomical landmarks.
