duodenostomy การใช้

In the early 20th century, performing a duodenostomy was considered very unsafe.
Two of the more important developments in surgery advanced by Welch included the development of a safe method of performing a catheter duodenostomy and performing the first replacement of an artery with a vein graft at MGH.
After discovering two other surgeons who had used a similar technique, Welch reported this new method of performing a duodenostomy to the " Journal of the American Medical Association " ( JAMA ) in 1949.
