William L. Diehl, M.D., F.A.C.S.
A specialist in cancer surgery, Dr. Diehl completed his training at the prestigious Memorial Sloan Kettering Cancer Center in New York.
With extensive expertise in the field of surgical oncology, he has a special interest in breast cancer and was one of the first surgeons to perform sentinel node mapping procedures, which reduce the need for extensive surgery. He also is heavily involved and skilled in the treatment of other types of tumors. As a result of the multiple pancreatic cancer resections he performs, Morristown Memorial Hospital is considered a “high-volume hospital” for the performance of pancreatic cancer surgery.
Dr. Diehl has special training and expertise in the treatment of tumors of the pancreas, liver, biliary tract and esophagus. Other areas of interest include melanomas, colon and rectal surgery, thyroid surgery, and other head and neck cancers. He was the first to perform Single Site Laparoscopy (SSL), also known as Single Incision Laparoscopic Surgery (SILS), at Morristown Memorial Hospital and has used the procedure for appendectomies, colectomies, gallbladder removal and other surgeries.
From 1986 through 1988, he completed his Fellowship in Surgical Oncology at Memorial Sloan Kettering. He has been in private practice and on staff at Morristown Memorial Hospital since then.
Dr. Diehl is board certified and an attending surgeon at Morristown Memorial Hospital, where he is head of the Multidisciplinary Breast Cancer Panel. He is actively involved in surgical research and in teaching within what is one of the premiere residency programs in the state. He has been awarded the John Alkhas Teaching Award at Morristown Memorial Hospital.
He is the past President of the Morris County Medical Society and the Morris Unit of the American Cancer Society. Dr. Diehl has consistently been chosen during the past several years as Top Doctor in New Jersey Monthly magazine's annual survey of physicians. In 2007 he also received the Annual Humanitarian Award by sharingVillage, a self-help and educational cancer survivor support group (www.sharingvillage.com) serving Morris and Somerset Counties.
