Range of services
Dr. Köstler studied and trained in general surgery. He has worked in many hospitals, which gave him the opportunity to gain a wide range of surgical experience in various settings.
At the canton hospital in Winterthur he was, for example, able to gain extensive knowledge in emergency surgery. As chief doctor in the hospitals Lachen and Limmattal, traumatology was one of his core areas of focus. He led the trauma department in the hospital Limmattal from 2005 to 2011, and implemented numerous contemporary and innovative features (e.g. angle-stable implants, new nail systems, new access paths in hip prosthetics (ventral approach), etc.).
Visceral surgery (surgery of the abdominal organs) has been a focus since the beginning of Dr. Köstler’s professional career. Within visceral surgery, he was highly interested in minimally invasive surgical techniques from the outset. This «keyhole surgery» enables complex visceral surgical operations (abdominal surgery) without imposing a large surgical trauma on the patient.
Alongside traumatology, these laparoscopic, minimally invasive surgeries on the colon, small intestine, stomach, gallbladder, bile ducts, and hernias (for example, inguinal hernia or abdominal hernia) increasingly became his professional focus.
In recent years Dr. Köstler has specialized further and has directed his skills toward bariatric surgery («obesity surgery»). He has been performing bariatric surgery by laparoscopy since 2003, and since then he has performed most of the bariatric surgeries at the hospital Limmattal.
Dr. Köstler has treated approximately 1300 bariatric patients since 2003. Due to his high interest in this field, and the increasing numbers of patients, he is head of the bariatric department at the hospital Limmattal, and the leading specialist. He is also supported by a highly skilled team of different specialists in obesity treatment at the hospital Limmattal.
He performs more than 200 bariatric operations per year at the hospital Limmattal which is recognized by BAG (Federal Office of Public Health) as a reference centre for bariatric surgery.
One of his areas of expertise is complex bariatric surgery. This includes surgery on extremely obese people (BMI > 50) and secondary operations due to chronic abdominal pain or insufficient weight loss after a primary surgery.
Since 2012 he has also been working as consultant physician for bariatric surgery at the University Hospital Basel.
