Dr. Clifford LeMaster and Students Published in Surgical Endoscopy

Dr. Clifford LeMaster, Professor in the Boise State University Department of Chemistry & Biochemistry, in collaboration with local surgeons Thomas Huntington, M.D. and Ciara Huntington, M.D. of St. Luke’s Regional Medical Center and Boise State University students Jonathan Prince, Kerstin Hazelbaker, Bradley Lopes, & Tyler Webb, recently published a manuscript entitled “Safety First: Significant Risk of Air Embolism in Laparoscopic Gasketless Insufflation Systems” in the journal Surgical Endoscopy (

Gasketless insufflation systems are marketed for use in the United States and advertise the ability to prevent abdominal collapse and desufflation during laparoscopy. However, community surgeons Thomas Huntington, M.D. and Ciara Huntington, M.D. raised concern for the potential entrainment of room air into the abdomen during laparoscopy and increased risk of fatal nitrogen embolism with these systems, and this team’s collaborative research efforts found these concerns to be justified.

The authors have submitted two separate Food and Drug Administration complaints with their experimental findings to communicate the potential hazard of these devices, and current marketers of this technology were approached directly by the research team with concerns for patient safety based on this research. The team with also be contacting the EMA (European Medicines Evaluation Agency), which is the European Union’s equivalent to the U.S. Food and Drug Administration (FDA), with the findings. Dr. LeMaster’s research team plans future collaborative studies on the risks involved.
