Minimally invasive and precise are the themes and the philosophy pursued in contemporary surgery. With the application of advanced laparoscopic equipment and the advancement and maturity of laparoscopic technology, and with the fine laparoscopic instruments and the enlargement of the surgical field, many operations are more delicate, making precise surgical techniques possible. minimize the trauma of patients and provide a guarantee for their rapid recovery. However, because of the deep anatomical location of the bile duct and pancreas, the surrounding blood vessels are rich and difficult to resect, and the precise anastomosis with the intestine is required after resection, so it has been the bottleneck of minimally invasive surgery, especially laparoscopic pancreaticoduodenectomy, which has been in a slow development and exploration stage in China. In the past year or so, under the leadership of Professor Wang Jian, the Department of Biliary and Pancreatic Surgery has ventured into the forbidden area of surgery and continuously challenged the difficult surgery, and has successfully carried out laparoscopic pancreaticoduodenectomy and laparoscopic biliary cystectomy and bile-intestinal anastomosis. It is a physical, mental and volitional challenge for the medical staff. The advent of the da Vinci robot, with its 3D imaging, 10x image magnification, and fibrillation elimination technology, has solved the bottleneck of complex laparoscopic biliary and pancreatic surgery. With a remote console, special surgical instruments, and high-definition lumpectomy equipment, the system “can see areas that cannot be seen by human eyes and can do actions that cannot be done by human hands,” making it the most advanced field in the development of minimally invasive surgery. The robotic system’s mechanical arm can rotate 360 degrees, making suturing precise and convenient, while providing a clearer surgical field of view and a more accurate imaging system, making the surgery more delicate, precise and accurate, with less intraoperative bleeding and ultimately achieving rapid postoperative recovery, reflecting its unique minimally invasive advantages in biliary and pancreatic surgery. This surgical system expands the field of lumpectomy surgery and breaks through the bottleneck of limited development of laparoscopic surgery because it solves the limitations of traditional laparoscopy in terms of field of vision and flexibility of operating instruments, making minimally invasive biliary and pancreatic surgery extend to practical, difficult and high-risk large-scale surgery. ”Although the biliary tract and pancreas are located deep and hidden, and the operating space is narrow, the robot can easily complete operations such as separation, hemostasis and suturing because of its flexible rotating inner wrist. And the robot’s left and right hands are flexible, such as the ‘left hand’ holding bipolar electrocoagulation and the ‘right hand’ holding ultrasonic knife or needle holder, opening the bow at the same time, making lesion removal more rapid and anastomosis more precise.” Prof. Wang said. But Professor Wang also believes that while da Vinci robotic surgery is a boon to patients, it is a huge challenge for surgeons. Operating robotic surgery requires surgeons to have precise knowledge of local anatomy, rich surgical experience and good psychological quality. For example, if they encounter heavy bleeding in traditional surgery, doctors can immediately stop the bleeding by blocking it with gauze. This is unthinkable in robotic surgery. In order to avoid heavy bleeding, every action of the surgeon must be very sure, which requires a very high degree of familiarity with anatomy and precision of the main surgeon. Since its establishment one and a half years ago, the Department of Biliary and Pancreatic Surgery, under the leadership of Professor Jian, the chief of the Department, has applied the concept of “minimally invasive precision surgery” to complex hepatobiliary and pancreatic surgeries. While curing the patients, we minimize the trauma of the patients and provide guarantee for their rapid recovery. At present, we have successfully performed robotic pancreaticoduodenectomy, robotic choledochal cystectomy with bile-intestinal anastomosis, robotic spleen-preserving pancreatic caudal resection, robotic combined spleen pancreatic caudal resection and robotic liver lobectomy. With the successful performance of more and more robotic surgeries, it marks that the biliary and pancreatic surgery department of Renji Hospital has entered the “minimally invasive and robotic era”.
