About me

Mr Markakis is a General, Upper gastrointestinal and Bariatric Surgeon based at University College Hospital and The London Clinic. His subspecialty interests include metabolic and bariatric (weight-loss) surgery, abdominal wall hernia surgery and upper gastrointestinal surgery particularly hiatus hernia and gallbladder surgery.

Bariatric Surgery

Mr Markakis has extensive experience in weight management including treatment with weight loss medications (Saxenda, Wegovy) and bariatric surgery for people living with severe and complex obesity. He performs all major bariatric procedures including gastric band, sleeve gastrectomy, one anastomosis (�mini� gastric bypass), Roux-en-Y gastric bypass and single-anastomosis duodeno-ileostomy (SADI) and has an interest in revisional bariatric surgery for the treatment of complications including acid reflux, but also weight regain both after gastric bypass and sleeve gastrectomy with a combination of pharmacotherapy and revisional surgery including endoscopic options (Apollo Overstitch). He is the highest volume surgeon in University College Hospital where the bariatric surgery team focuses on the most complex procedures including high-risk patients, revisional surgery and management of complications.

Hernia surgery

Mr Markakis� focus on minimally invasive (�keyhole�) surgical techniques means he can offer laparoscopic and robotic surgery for complex procedures that would otherwise require open surgery. This is particularly relevant to abdominal wall hernia surgery where he performs >95% of all procedures laparoscopically and this includes inguinal, epigastric, incisional, lumbar, spigelian, and parastomal hernias as well as repair of rectus abdominis divarication (diastasis recti). He was one of the first surgeons in the UK to introduce laparoscopic retro-rectus (eTEP Rives-Stoppa) and transversus abdominis release (TAR) techniques for ventral and incisional hernia surgery which have enabled the successful application of laparoscopic and robotic surgery for complex abdominal wall hernias. Preoperative optimisation is key to prevent complications and hernia recurrence and Mr Markakis utilizes his experience in weight management to improve outcomes for patients undergoing abdominal wall hernia surgery. This is combined, when indicated, with robotic-assisted surgery which facilitates hernia repair for patients living with obesity.

Upper gastrointestinal surgery and endoscopy

At the London Clinic our team offers a range of endoscopic and surgical options for the management of a range of pathology that includes acid reflux, hiatus hernia and achalasia. Mr Markakis specializes in the minimally invasive management of large hiatus and paraoesophageal hernias and his research experience has enabled him to develop a deep understanding of the use of prosthetic materials for the most complex of these hernias.

Mr Markakis performs preoperative and postoperative endoscopy including for diagnosis, preoperative planning for hiatus hernia and bariatric surgery and therapeutic endoscopy for management of complications.

Mr Markakis performs cholecystectomy using keyhole techniques in 100% of patients including when this is complicated by morbid obesity. He has an excellent safety record having never caused a bile duct injury or duodenal/bowel injury during cholecystectomy.
