About the department

The general surgery department at Memorial Sisli Hospital Istanbul offers surgical treatment at the highest level of modern medicine. The department's surgeons and nursing staff work diligently to provide excellent patient care and pride themselves on their reputation for surgical care. Doctors working in a medical institution keep pace with innovations. Therefore most surgical interventions are performed using gentle, minimally invasive, endoscopic and robotic techniques, which today are the gold standard of progressive international medicine. For a quick and accurate diagnosis, the department has state-of-the-art CT and MRI, endoscopic equipment and equipment for ultrasound diagnostics. Treatment is carried out on an outpatient and inpatient basis. For emergency cases, a medical team is available around the clock.

The priority clinical tasks of the department's doctors include surgical treatment of diseases of the abdominal organs, including the stomach, small and large intestines, liver, pancreas, gallbladder and biliary tract, as well as hernias and pathologies of the oesophagus and thyroid gland. Doctors also perform colorectal surgery in patients with colon and rectal cancer, ulcerative colitis, and Crohn's disease. Therefore, the department became an SRC Center of Excellence in Colorectal Surgery. As a rule, one surgical intervention is not enough to achieve a stable remission, so radiation therapists, chemotherapists, nutritionists, physiotherapists and other doctors are involved in the treatment process.
