10ml Minimally Invasive Miracle! Robotic Precision Excision of Segment S2 Liver Tumor
10ml Minimally Invasive Miracle! Robotic Precision Excision of Segment S2 Liver Tumor
Recently, the team led by Director Xing Wenjun from the Second Department of Hepatobiliary Surgery at the Hepatobiliary Center of Wuwei Cancer Hospital successfully performed a precision resection of a liver tumor in Segment S2 for a patient from Beijing, utilizing a surgical robotic system. The entire procedure lasted only 2 hours, with intraoperative blood loss as low as 10 milliliters, once again highlighting the revolutionary advantages of robotic minimally invasive surgery in the field of hepatobiliary surgery.
Precision Preoperative Assessment:
Based on clear CT imaging, the team meticulously planned the resection boundaries, ensuring complete tumor removal while preserving as much healthy liver tissue as possible.


Technology empowers, ushering in a new era of precision surgery
In the operating room, Director Xing Wenjun's team worked in seamless coordination with the surgical robot. While the surgeon performed precise maneuvers at the console, the robot's flexible mechanical arms steadily and meticulously separated tissues and identified blood vessels within the patient's body. The high-definition 3D visual system magnified the surgical area severalfold, making even the finest blood vessels and bile ducts clearly visible, laying a solid foundation for the precision resection. The procedure resulted in a blood loss of only 10 ml, and the patient was able to get out of bed and move around on the same afternoon—a vivid demonstration of modern surgery's evolution toward super-minimally invasive techniques and rapid recovery.
The robot completed its self-check. Director Xing Wenjun sat before the console, his hands resting on the control levers like a conductor poised to begin a symphony of life. His gaze was calm, his fingertips moved subtly, and the mechanical arms danced in response. There was no glint of a scalpel, yet precision prevailed; no visible traces of blood, yet every step was filled with tension. Following commands, the robot cut into the liver tissue with millimeter-level accuracy, as if sculpting a masterpiece where no error was allowed. Two hours passed like a silent marathon, where every single move counted.

Sterile drapes were spread out as the robotic arms descended slowly, resembling a group of silent guardians. On the screen, the surgical field was magnified several times, revealing the intricate texture of the liver tissue like woven brocade, with the tumor's boundaries unmistakably clear in the high-definition imaging. The assistant kept a close watch on the display, ready to respond to instructions at any moment. Each subtle adjustment tested both experience and tacit understanding. In this environment, there was no noise—only the rhythm of breathing and heartbeat, weaving together with the tireless "robot" to create a web of safety.
Intraoperative Precision Decision-Making: Leveraging extensive experience and real-time feedback from the robotic technology, the surgical team flawlessly executed the planned procedure.
Do the gentlest things with the calmest mind

The robotic arm gently dissected within liver segment S2, precisely ligating blood vessels, bile ducts, and the segmental hepatic pedicle, while tissues were meticulously layered and separated. The assistant adjusted the angle, and the lead surgeon smoothly guided the handles—each movement flowing with practiced ease. Ten milliliters of blood loss, almost negligible—this was not luck, but instinct honed through countless hours of training. No one spoke in the operating room, yet everyone knew: this battle was won.

The three of them stood around the robot, like guardians of a moving fortress of life. As the surgery drew to a close, suturing began. Each stitch was placed with precision, and the liver surface lay as smooth as newly healed earth. The infusion stand hung silently, while numbers on the equipment screens pulsed steadily. At this moment, technology was no longer a synonym for coldness, but rather the hand that bore the weight of life.

Definitive Pathological Diagnosis: The postoperative pathology report conclusively confirmed the diagnosis as "nodular hepatocellular carcinoma, moderately differentiated." The tumor was completely excised with negative margins, achieving an R0 resection. Additionally, the surrounding liver tissue was thoroughly assessed, providing a definitive basis for subsequent treatment.

The report is out. Within the 6.5-centimeter specimen lies a 3.5-centimeter mass—a moderately differentiated hepatocellular tumor hidden beneath a grayish-white section. Under the microscope, cells appear disorderly, nucleoli are prominent, and mitotic figures are frequent—it once grew wildly, but now it has become history. The diagnosis is clear: nodular hepatocellular carcinoma, not otherwise specified. The immunohistochemistry results are appended at the end, like a comprehensive verdict. Yet no one is disheartened, because the surgery has achieved an R0 resection of the lesion. This report is no longer a source of fear but the starting point of recovery.

MDT (Multi-Disciplinary Team) In-Depth Integration to Formulate Individualized Precision Treatment Plans
The success of this surgical case was made possible by the robust multidisciplinary team (MDT) model of the hospital's Hepatobiliary Center. Prior to the surgery, experts from multiple disciplines—including the Second Department of Hepatobiliary Surgery, the Imaging Department, and the Hepatology Department of the Hepatobiliary Center—conducted in-depth and meticulous MDT consultations tailored to the patient's condition.

This surgery not only demonstrates technical excellence but also perfectly embodies the patient-centered, multidisciplinary collaboration-based, and precision minimally invasive-oriented treatment philosophy of the Second Department of Hepatobiliary Surgery at the Hepatobiliary Center of Wuwei Cancer Hospital. By integrating the strengths of internal medicine, surgery, and related disciplines, the Center provides every patient with liver and gallbladder diseases a comprehensive, personalized, and optimal treatment plan—spanning from diagnosis and surgery to postoperative management. This approach has truly achieved a leap forward in clinical standards, enabling more patients to benefit from the advancements of modern medical technology.
