About the department

The department of general, abdominal, oncosurgery at Teknon Medical Center Barcelona specializes in laparoscopic treatment of the gastrointestinal tract. The experience of the department's medical team includes more than 12,000 laparoscopic interventions in the abdominal cavity and gastrointestinal tract. The department is also training laparoscopic surgery for surgeons worldwide, especially from Latin America. In 2011, the International Federation for the Surgery of Obesity and Metabolic Disorders accredited the department as a Center of Excellence for Metabolic and Bariatric Surgery. Currently, specially trained teams can perform by laparoscopy a large number of operations that were previously performed by open surgery, such as gastroesophageal reflux and hiatal hernia, operations on the colon, adrenal glands, and spleen.

The department's key focus is the diagnosing and treating all pathologies of the gastrointestinal tract, including inflammatory, autoimmune, and oncological. The department is equipped with five operating rooms for outpatient surgical interventions so that the patient can leave the hospital on the same or the next day after the operation. Particular attention is paid to the treatment of obesity, which affects more than 30% of the population. Together with nutritionists, psychologists and physiotherapists, surgeons select the most optimal treatment for patients. Doctors also adhere to minimally invasiveness with malignant tumours and achieve the best results.
