Minimally Invasive (Laparoscopic) Surgeon

Dr Ozmen is passionate about laparoscopic “keyhole” surgery, which offers patients less cosmetic scarring, less post-surgical pain and faster recovery times when compared to conventional “open” surgery.

Dr Ozmen has performed over 5,000+ laparoscopic operations; with over 1,500+ of them in the field of bariatric surgery (including lap band surgery, sleeve gastrectomy, gastric bypass, and revisional procedures for failed bariatric surgery performed elsewhere).

In this photo, Dr Ozmen can be seen using the new ‘mini port’ laparoscopic technique, which leaves near invisible scars on the patient post-surgery.

Areas of Expertise:

  • Weight loss surgery: gastric sleeve, bypass
  • Hernia surgery: abdomen and groin
  • Reflux (GORD) surgery: hiatal hernia, fundoplication
  • Gallbladder: cholecystectomy and gallstones

Medical Research:

Dr Ozmen has a strong interest in medical research and advancing new surgical treatments, and was lead author on a peer reviewed scientific study into hernia surgery – comparing post-surgery pain after laparoscopic hernia surgery using a self-gripping mesh versus conventional methods.
