On the occasion of the 110th Anniversary of the establishment of the Chinese Medical Association, the third conference of the Fourth Editorial Board of Chinese Journal of Digestive Surgery, and the Second Elite Group of Chinese Journal of Digestive Surgery, was successfully held in Kunming on July 4, 2025. This conference systematically summarizes the development experience of the journal over the past 20 years from three aspects: the role of ecological construction of thought in the discipline construction of digestive surgery, the display of the latest academic achievements in the field of digestive surgery, the development difficulties, and breakthrough paths of the discipline, and strategically plans the path of discipline construction in the new era.

Hospitals presently confront multiple challenges, including rapid technological advancements, escalating healthcare demands, and continuously rising healthcare costs, thereby necessitating the introduction of new quality productive forces to drive high-quality hospital development. Adopting the perspective of new quality productive forces, the authors examined the transformation trend from conventional fragmented medical services towards integrated digital healthcare systems. Through the establishment of digital infrastructure characterized by big data, cloud computing, the Internet of Things, and artificial intelligence, hospitals could realize deep integration between inpatient and outpatient care, as well as seamless online and offline service delivery. Concurrently, oriented by the healthcare needs of residents, a precise and efficient " prevention-diagnosis-treatment-rehabilitation" service mode was proposed. This mode could facilitate the extension of innovation and industrial chains originating from healthcare services, expedite the translation of research outcomes into practice, and promote scientifically meticulous hospital management. Collectively, these measures could enable hospitals to develop patient-centered, comprehensive life-cycle healthcare service systems, thereby promoting the high-quality development of hospitals.

With technological innovation and conceptual advancements, minimally invasive surgery (MIS) has been widely adopted across nearly all surgical specialties, establishing itself as a mainstream surgical procedure. In recent years, with the ever expanding application of laparoscopic surgery and robotic surgery, as well as continuous breakthroughs in novel MIS instruments and artificial intelligence, the precision and safety of MIS in complex surgeries have been further enhanced. Embracing the philosophy of multidisciplinary integration, MIS is progressing toward safe, non-invasive, and intelligent practices, delivering personalized and precise minimally invasive treatments to patients.

Objective:To summarize the initial experience of 5G-ultra-long-distance robotic hepatectomy.Methods:This is a retrospective case series study. The clinical information from 5 cases of 5G ultra-long-distance robot-assisted hepatectomy performed was collected from June 2023 to October 2024, in collaboration between Sir Run Run Shaw Hospital, Zhejiang University School of Medicine in Hangzhou and Alaer Hospital, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine in Alaer, located 4 600 km apart. The patients comprised 1 male and 4 females, aged from 36 to 59 years, with an average age of 48 years. Their body mass index ranged from 20.4 to 30.9 kg/m2, with an average of 24.62 kg/m2. Preoperatively, 5 patients were diagnosed with liver disease requiring hepatectomy. The operations used 5G ultra-remote four-arm endoscopic robot surgery system. The remote control room was located in Sir Run Run Shaw Hospital (Hangzhou, Zhejiang), and the robot operating room was located in Alaer Hospital (Alaer, Xinjiang). The wired network relied on 60 Mb/s high-speed public Internet special line (China Telecom). In order to ensure the security of data transmission, the system implemented a double-layer encryption strategy for the wired network, and carried out strict debugging and verification for both the wired and wireless networks. Perioperative data and information on network performance were collected for 5 patients.Results:The surgical duration of the 5 cases of 5G ultra-long-distance robot-assisted hepatectomy ranged from 49 to 342 minutes, with an average of 184 minutes. Intraoperative blood loss varied from 5 to 800 ml, averaging 183 ml. Network performance was evaluated during the surgery, revealing an average network latency of 108.2 ms, with no significant lag or delay observed during any of the procedures. All patients recovered smoothly, with a postoperative hospital stay ranging from 5 to 10 days, averaging 7.2 days. Postoperative complications included 1 case of hypoproteinemia and 1 case of pleural effusion. Pathological examination confirmed that all cases suffered benign liver diseases (three patients with hepatic hemangioma, one with regenerative nodule in cirrhosis, and one with hepatolithiasis and choledocholithiasis).Conclusion:The preliminary exploration of clinical practice indicated that 5G-ultra-long-distance robot-assisted surgery is feasible for hepatectomy, with no severe complications affecting patients′ recovery.

The combination of mobile communication technology and the medical field has given rise to telemedicine, whose clinical practice can greatly alleviate the problem of uneven distri-bution of regional medical resources and provide patients with instant and high-quality diagnostic and treatment services. The concept of telemedicine has also been applied in the field of surgery. With the rapid development of high-speed communication technology and robotic surgery systems, remote robotic surgery is gradually entering people′s vision. However, remote robotic surgery requires extremely high speed and stability in long-distance information exchange, and traditional communi-cation technologies are gradually unable to meet the development needs of remote robotic surgery. The fifth generation mobile communication technology, namely 5G network, is bringing significant changes to the development of remote healthcare, especially remote robotic surgery, due to its advantages such as high speed, high bandwidth, and low latency. The author has consulted relevant literature and combined with the team′s experience in conducting 5G remote robotic surgery, provi-ding a detailed introduction to the current application status and future prospects of 5G network based remote medical robotic surgery, aiming to promote the deep development and further promo-tion of this new technology.
