Led by Director Prof. Leng Jianjun, the team from the Hepatobiliary and Pancreatic Surgery Center of Peking University Shougang Hospital has consecutively completed more than 20 complex high-difficulty operations using domestically developed Shurui Single-Port Surgical Robot with snake-like instruments. These challenging procedures, all performed with the Shurui robotic system, include the first robotic pancreaticoduodenectomy of its kind, precise resection for complex liver cancer, and pancreatic duct-jejunum Roux-en-Y anastomosis.This series of clinical cases has verified the maturity and reliability of the Shurui robotic system for complex scenarios in hepatobiliary and pancreatic surgery.

In the field of abdominal surgery, hepatobiliary and pancreatic procedures have long been regarded as one of the most technically demanding subspecialties due to complex anatomical structures, proximity to major blood vessels, fragile tissues, and high postoperative complication risks. Among these, pancreaticoduodenectomy (PD), involving multi-organ en bloc resection and triple digestive tract reconstruction, demands extreme surgical experience and instrument precision, earning it the title "Crown Jewel of Surgery." Procedures including reconstructive anastomosis and complex hepatectomy similarly serve as the litmus test for minimally invasive surgical proficiency due to complex anatomical architecture, confined operative workspace and significant hazards in vascular handling.

Pancreaticoduodenectomy, with its extensive resection scope, multiple anastomotic reconstruction steps, and high intraoperative bleeding risk, poses the most stringent test of a surgical robotic system's stability, fine manipulation capability, and overall coordination.

All PD surgeries performed by Prof. Leng Jianjun's team were real-world consecutive cases. Take one typical patient as an example: a 64-year-old male diagnosed with pancreatic head cancer complicated by low-level biliary obstruction, who underwent preoperative bile duct puncture and drainage to relieve jaundice. Due to the tumor's deep location, close relationship with the portal vein and superior mesenteric vein, combined with the patient's frail constitution and poor preoperative general condition, traditional multiport laparoscopic or open surgery posed significant trauma and recovery risks.

Prof. Leng Jianjun’s team completed a radical pancreaticoduodenectomy entirely using the Shurui® Single-Port Surgical Robot with snake-like instruments. The surgery was performed through a single approximately 2.5cm umbilical incision where a multi-channel sheath was inserted, allowing three snake-like instruments to establish a 360-degree unrestricted workspace within the abdominal cavity. During the procedure, leveraging the robotic arms' 120-degree omnidirectional bending capability and 3D "cobra" perspective endoscopic visualization, the team precisely performed layered dissection of the portal vein, hepatic artery, and lymph nodes, successfully completing three anastomoses: pancreaticojejunal, cholangiojejunal, and gastrojejunal. Intraoperative blood loss was controlled within 100ml, with virtually no visible bleeding. The patient was able to ambulate on the second postoperative day, experienced no complications such as pancreatic fistula or bile leakage, and was discharged smoothly on postoperative day 16.

Beyond PD procedures, Prof. Leng Jianjun's team has completed multiple equally challenging hepatobiliary and pancreatic surgeries assisted by the Shurui® Robot.

Precision Resection of Complex Liver Cancer:A 63-year-old patient with hepatocellular carcinoma had a tumor located in liver segments S4b and S5v, closely abutting the right anterior pedicle, with suspected intrahepatic major vascular invasion. The patient also had a background of post-hepatitis cirrhosis. Under traditional protocols involving combined liver lobe resection, the risk of postoperative liver failure was extremely high. Prof. Leng's team first administered conversion therapy (TACE combined with targeted immunotherapy), reducing the tumor from 7.5cm to 4.6cm, then performed precise liver segmentectomy using the  Shurui®single-port robot. The  snake-like instruments, inserted through a 3-4cm umbilical incision into the abdominal cavity, achieved fine dissection of tumor-vascular adhesions with 120-degree omnidirectional bending and 540-degree axial rotation of the gripper tips. The procedure was blood transfusion-free, and the patient recovered well postoperatively.

Prof. Leng Jianjun's team has completed over 20 complex hepatobiliary and pancreatic surgeries using the Shurui® Single-Port Surgical Robot with snake-like instruments, covering the following procedures:

"The successful implementation of high-difficulty procedures such as pancreaticoduodenectomy is not a breakthrough in a single technical point, but rather a concentrated reflection of the Shurui® Single-Port Surgical Robot with snake-like instrument’'s systemic capabilities," Prof. Leng Jianjun remarked in his postoperative evaluation. "This system has three core advantages: First, the serpentine arm's omnidirectional bending capability (120 degrees) fundamentally solves the 'chopstick effect' of traditional single-port surgery, maintaining flexible operation even in deep, narrow spaces; second, the robotic arm delivers approximately 10 Newtons of load, allowing controllable traction on fragile organs like the liver and pancreas to avoid accidental tearing; third, the 3D endoscope can switch to 'cobra mode,' bypassing organ obstructions to provide a clear view, significantly enhancing surgical safety margins."

Prof. Leng emphasized: "We adopted a leasing model to introduce the Shurui robot, lowering the initial threshold for applying advanced technology. The smooth execution of nearly 30 surgeries demonstrates that domestically produced single-port robots have the potential to replace imported multiport robots in the most complex scenarios of hepatobiliary and pancreatic surgery."

Pancreaticoduodenectomy and complex hepatectomy — procedures once representing the pinnacle of open surgical techniques — can now be performed in a less invasive, more precise and safer manner with assistance from the Shurui® Single-Port Surgical Robot with snake-like instruments.In the future, Shurui Robot will continue to collaborate with leading clinical centers, accumulate evidence-based data, standardize technical pathways, and promote the standardization and popularization of single-port robotics in the field of hepatobiliary and pancreatic surgery, contributing the innovative power of domestically produced high-end medical equipment to "Healthy China."
