Joseph B Petelin, MD, FACS
Joseph B. Petelin, MD, FACS, graduated from the University of Kansas School of Medicine and received his doctorate in 1976. He completed his surgical residency at the same institution in 1981, and subsequently was appointed to the clinical faculty of the University in the same year. He has been certified and twice re-certified by the American Board of Surgery. He is currently a member, in good standing, of the American College of Surgeons.
Petelin’s undergraduate work in physics and his interest in computer science has been influential in shaping his career path since that time. In the late 1980s, he spent considerable time teaching the principles and application of laser technology to surgeons around the United States. This activity proved to be the platform from which the current renaissance of laparoscopic surgery would emerge. It was during this time that Petelin and other pioneers in the filed of laparoscopic surgery developed many of the techniques that are used around the world today.
Petelin personally developed the first sets of curved instruments for use in laparoscopic surgery in 1989. These instruments enabled operations that were not possible prior to their invention. In that same year, he developed the technique of percutaneous cholangiography, which has since become standard worldwide. His interest in biliary tract surgery naturally led to development of laparoscopic techniques for the removal of common duct stones. He produced the first papers, texts and videos detailing the laparoscopic common duct exploration, and has lectured on this subject and many others worldwide. He currently still has the world’s largest personal series of laparoscopic cholecystectomies, more than 5,500, and the largest series of laparoscopic common bile duct explorations, more than 400. His interest and success in this particular area have earned him an international reputation for his pioneering work in laparoscopic treatment of biliary tract disease.
Petelin’s work was integral to the expansion of laparoscopy in the early 1990s. In 1991 he performed the world’s first laparoscopic splenectomy, the first laparoscopic pancreatic pseudocyst-gastrostomy and the first laparoscopic gastrojejunostomy. He produced the first report on laparoscopic adrenalectomy for the 2nd World Congress of Endoscopic Surgery in Bordeaux, France in 1992. He has performed almost all types of laparoscopic surgery, including more than 5,000 laparoscopic hernia repairs and more than 1,000 laparoscopic colectomies. In all, he has performed more than 20,000 laparoscopic surgical cases.
In the early 1990s he developed a computer-assisted robotic camera manipulator, the AutoScope™, for use in minimally invasive surgery (MIS). This device was the first of its kind. This produced more accurate visualization than had been possible prior to that time. Since then, the industry has further developed other computer-assisted tele-manipulative devices that also improve the accuracy of laparoscopic surgery.
His technical expertise in the field of laparoscopic surgery led to the requests for live operative demonstrations throughout the world in the 1990s. He has performed multiple advance laparoscopic procedures for audiences of literally thousands of surgeons in England, France, Spain, Switzerland, Italy, Kazakhstan, China, New Zealand, Hong Kong, Canada, Israel, India and others. In 2006, he produced a live webcast of a laparoscopic sigmoid colectomy that was observed live on the Web by more than 1,200 sites, and has since been seen by more than 20,000 others.
Petelin sits on the editorial boards of the most influential peer-reviewed laparoscopic journals in the world. He has published extensively on a wide variety of laparoscopic subjects, including colectomy, adrenalectomy, enterolysis, anti-reflux surgery, intestinal surgery, robotic surgery, etc. He has also produced numerous video-based educational tools for surgeons and patients.
In 1995, he was elected President of the Society of Laparoendoscopic Surgeons, one of the premier international laparoscopic surgical organizations in the world.
In 1996, Petelin was named to the Board of Governors of the Society of American Gastrointestinal Endoscopic Surgeons (SAGES), one of the largest international organizations of surgeons interested in MIS.
Petelin continues his active involvement in the leadership of both of these societies.
Petelin is a founding member of the MIS Fellowship Council, a national organization that oversees the development and management of minimally invasive surgical fellowships. These fellowships have become the most sought after post-graduate surgical training opportunities in the world. The organized surgery establishment has recognized the importance of the fellowships and in 2003 inaugurated the first MIS fellowship match program. The Fellowship Council has assumed a vital role in the activities of the American Board of Surgery.
Petelin continues to pursue the development of this exciting field.
Glenn A. Deyo, MD, FACS
Glenn A. Deyo, MD, FACS, graduated from the University of Texas Medical School at Houston and received his doctorate in 1982. He completed his surgical internship and residency at Madigan Army Medical Center in Tacoma, Wash. Deyo is certified and twice re-certified by the American Board of Surgery and is a fellow of the American College of Surgeons and International College of Surgeons.
Deyo served in the U.S. Army from 1973 to 1992 as a Special Forces Weapons Specialist and Medic and later as a General Surgeon. He was activated from his surgical residency for a combat jump with the 2nd/75th Ranger Battalion into Grenada for Operation Fury. Deyo was again activated out of his practice at the peak of laparoscopy in 1991 to support Operation Desert Storm.
With a special interest in gastroesophageal reflux disease, Deyo has completed more than 1,000 laparoscopic Hill hiatal herniorrhaphies. He has completed several thousand laparoscopic procedures and has served as a lecturer and instructor for a number of laparoscopic courses, training surgeons worldwide.
Deyo has given numerous presentations on topics concerning laparoscopic surgery to include cholecystectomy, inguinal and hiatal herniorrhaphy, and perforated viscus repair. He has also published works on the subjects of laparoscopy including cholecystectomy, complications, inguinal herniorrhaphy and perforated ulcers.
Deyo performed the first laparoscopic cholecystectomy in the Pacific Northwest in 1989, and was the first surgeon to perform this procedure, as well as a transperitoneal inguinal herniorrhaphy, under local anesthetic. He is also the first in the Northwest to treat traumatic colon perforations and perforated diverticulitis with a laparoscopic repair and Graham patch.
In 1990, Deyo was the first to use the thumb of a sterile glove as an extraction bag; the first to use a Ray-Tec sponge during laparoscopy for retraction, dissection and hemostatic control; and performed the first flexible laparoscopic surgery using sterilized gastroscopes.
Deyo was Chief of Surgery at Puget Sound Hospital in Tacoma, Wash. from 1992-1993. He served as State Chairperson for the Society of American Gastrointestinal Endoscopic Surgeons. He is now a member of the Franciscan Acute Surgical Team, a subsidiary of the Franciscan Medical Group in Tacoma, Washington.
