How LapSurgery Australia began

LapSurgery Australia was established in 1984 by the two senior partners, Ray McHenry and Richard Gilhome. Today the clinic is operated by surgeons, Ray McHenry, Chris Hensman and Ara Saravanamuttu and has expanded to 6 locations including Boronia (Head Office), Berwick, Cranbourne, Frankston, Mulgrave and Warragul.

The practice offers a prompt referral service for patients who may need urgent consultation or review.

The surgeons offer a diverse range of services, practising general surgery as well as having their individual sub-specialties. They are unique in that they cooperate and assist each other with more complicated cases. They also advocate a team approach to patient care and thus provide an optimal service. This includes 24 hour 365 day per year cover for their patients and referring general practitioners.

Ongoing Medical Education and Introduction of New Technology

In order to provide optimal services, the Surgeons at LapSurgery Australia undertake extensive continuing medical education, regularly sourcing the latest technologies and trends overseas then incorporating these new ideas into the practice on return to Australia.

LapSurgery Australia pioneered the introduction of advanced laparoscopic surgery in our area with laparoscopic cholecystectomy in 1990. Laparoscopic (keyhole) surgery greatly reduces pain and the time taken to resume normal activities after surgery. Since then we have introduced to our area the operations of laparoscopic hiatus hernia (gastric reflux) surgery, laparoscopic appendectomy, laparoscopic inguinal hernia surgery and "keyhole" surgery for carpal tunnel syndrome. More specialised advanced laparoscopic procedures for treatment of severe obesity, including sleeve gastrectomy and, gastric bypass. Revisional surgery for previous obesity procedures is also available. We also offer medical and surgical management of Hyperhidrosis (sweaty palms and facial flushing). Many of these operations are exclusive to LapSurgery Australia in our area.

Exciting new developments were introduced in 1999 to include laparoscopic surgery for diseases of the large bowel and a new high-tech procedure for treating haemorrhoids promising much less pain than conventional operations. Mr Ray McHenry and Chris Hensman were the first to remove the entire large bowel and colon laparoscopically in 1999.

The Surgeons at LapSurgery Australia are now performing selected operations assisted by the Da Vinci XI surgical robot.

The team at LAPSurgery Australia are recognised for their exceptional and major contribution to the Government sponsored Bariatric Safety Registry (BSR). The BSR tracks surgical complications and provides an unbiased safety record for weight loss surgery.
