Minimally Invasive Surgeon

Dr Ozmen is passionate about minimally invasive “key hole” surgery, which offers faster recovery time and less post-surgical pain, and has performed over 3,000 laparoscopic operations; with over 1,000 of them in weightloss and 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.
