Introduction and Welcome to Surgery and Gastroenterological Surgery

At our department of Surgery and Gastroenterological Surgery, as a core regional hospital, our guiding philosophy is to provide "safe, reliable, and compassionate" surgical care. We treat a wide spectrum of conditions centered on gastrointestinal diseases—both malignant and benign—offering highly specialized, team-based medical care ranging from acute and chronic diseases to emergency surgeries.

We have established dedicated teams for specific diseases, allowing our physicians to leverage their individual expertise. Dedicated specialists take full responsibility for each field—including upper gastrointestinal, colorectal, hepato-biliary-pancreatic, and benign diseases (such as hernia and gallstones)—delivering consistently high-standard medical care from preoperative evaluation and surgery to postoperative follow-up.

We actively perform minimally invasive, patient-friendly procedures, such as laparoscopic and robot-assisted surgeries, with an annual volume exceeding 800 surgical cases. Beyond enhancing the quality of our treatments, we are dedicated to providing attentive care tailored to our patients' lives after discharge.
