[Discoveries and techniques that have contributed to improving the treatment of pancreatic diseases].

Due to its retroperitoneal location, the pancreas has historically been a mysterious organ that is difficult to examine and which complicates treatment. The discovery of anesthesia and asepsis in the mid-19th century allowed laparotomic diagnosis, which was previously only possible at autopsy. The expectations of surgery were improved by the detection of blood groups, vitamin K synthesis, and the development of intensive care units. In addition, high levels of presurgical diagnosis and an unquestionable improvement of its results were enabled by advances in laboratory methods (serum quantification of amylase and lipase, tumoral markers, genetics, and techniques for measuring exocrine pancreatic function), imaging and endoscopic modalities, and fine tuning of surgical techniques. In this article, we review the history of the main milestones that have allowed progress in all these aspects.
