Despite running a very busy surgical practice Dr. Gillian enjoys teaching residents and visiting surgeons some of the techniques he has developed over the years in all areas of laparoscopic surgery. Surgeons travel to watch Dr. Gillian perform a variety of procedures at INOVA Alexandria Hospital and Virginia Hospital Center. Many of these educational events have focused on laparoscopic inguinal hernia repair, laparoscopic incisional hernia repair, and the evaluation and correction of defects that cause heartbur/reflux and GERD. This would include Laparoscopic Nissen Fundoplication and the LINX procedure. Dr. Gillian runs one of only 4 training centers in the USA for LINX. Our methods for evaluation of these patients in the HEARTBURN CENTER with 24 hr pH and esophageal function testing with impedance technology is typically part of the training day.
