Dr Durmush

Medical Director and Surgeon

Dr Durmush is a general surgeon with particular interest in obesity surgery and advanced laparoscopy. He completed his surgical training in Germany, where he obtained the Arzt fuer Chirurgie (Fellow of General Surgery) in 1987. He was awarded a Fellow of the Australasian College of Surgeons in 1994 and in 2013 was awarded a Fellow of the International College of Surgeons. He has immense experience in laparoscopic surgery having performed over 5,000 laparoscopic operations to date.

As an advanced laparoscopic general surgeon, Dr Durmush became interested in obesity surgery in the late 1990’s which led him to Monash University, Melbourne , where he trained in laparoscopic gastric banding alongside the world renowned Professor Paul O’Brian. Dr Durmush, however, was not entirely convinced of the effectiveness of the band for sustained weight loss, especially for patients suffering from emotional and stress eating. Dr Durmush decided to address this deficit by attending a laparoscopic sleeve gastrectomy training program with Dr Leon Cohen, at the Mercy Bariatric Centre in Perth. As a result Dr Durmush was one of the first surgeons in Sydney to introduce the sleeve gastrectomy as a viable alternative to gastric banding.

The Life Weight Loss Centre was established shortly after By Dr Durmush, to provide a “Centre of Excellence” for obesity in 2007, and for this centre to offer a choice of surgical weight loss options ( more than just the gastric band) within a multidisciplinary environment (dietitians, clinical psychologists, exercise physiologists and bariatric surgeons) to cater for the needs of Sydney.

Since its inception the Life Weight Loss Centre has grown in reputation for its exceptional patient care, attention to detail and sustained weight loss. Dr Durmush has performed more thant 1200 sleeve gastrectomies with a complication rate of less than 0.5%, which is comparable to the results of the world leading bariatric surgeons. In fact, Dr Durmush was honoured by an invitation to address several European bariatric surgical meetings with regard to his sleeve gastrectomy leak management protocols and how to prevent leaks.

Dr Durmush is committed to ongoing research and data collection. In fact Dr Durmush’s recent journal article “Short-Term Outcomes of Sleeve GAstrectomy for Obesity: Does Stapleline Reinforcement Matter?” published in Obesity Surgery -The Journal of Metabolic Surgery and Allied Care in 2014 was nominated as one of the top ten most read articles for obesity by

In addition to obesity surgery Dr Durmush also performs surgery on all types of hernias, Gallbladder surgery, enoscopies, abdominoplasty and brachioplasty.

Dr Durmush is a full member of the Royal Australasian College of Surgeons (RACS), International Federation of Surgery of Obesity (IFSO), Obesity Surgical Society of Australia and New Zealand (OSSANZ) and International College of Surgeons.

As a point of interest Dr Durmush was nominated as “Australian Of The Year” for 2013 and 2014 consecutively.

Dr Vinh Hua

Consultant Anaesthetist


Since graduating in Medicine from Sydney University in 1995, I have worked at various tertiary teaching hospitals in NSW including 3 years at Westmead Hospital and 5 years at Liverpool Hospital. I have been practicing full-time anaesthesia for over 16 years. Currently I am a Visiting Consultant Anaesthetist at Westmead Private Hospital, St George Private Hospital, Hurstville Private Hospital, and Campbelltown Public & Private Hospitals. My current scope of anaesthetic practice encompasses many disciplines including emergency surgery, obstetrics & gynaecology, orthopaedics & trauma, urology, eye surgery, and general surgery including paediatrics. However, my most prominent area of anaesthetic practice is with Dr Durmush in bariatric obesity surgery (sleeve gastrectomy, gastric-banding and gastric-bypass).

Surgery and Anaesthesia is often a stressful time of high anxiety and apprehension. My professional motto is “First do no harm”, hence patient safety is of utmost importance in my practice. Amongst other things, patient satisfaction is also of paramount importance. I aim to provide a comfortable experience for the patient by providing adequate pain relief and preventing nausea and vomiting. Unfortunately, in medicine as in life, occasionally things don’t always go to plan, despite our best efforts. Complications do occur in anaesthesia, although very rarely, and Australia is one of the safest countries in the world to have anaesthesia. Most complications are minor, however, even with rare complications, with experience and expertise these complications can be well managed to ensure a complete and speedy recovery.

By sticking to the above principle of maintaining patient safety and satisfaction in the highest regard, I hope to allay your fears and ensure a positive experience through your life-changing journey. If you have any questions regarding the anaesthesia, I will be happy to answer all your questions at the pre-operative consultation and provide the necessary reassurance prior to your anaesthetic.
