Chinese team makes history with surgery
Print Edition
The Chinese University of Hong Kong said yesterday it had successfully preformed the world鈥檚 first colorectal endoscopic submucosal dissection recently by using a newly developed flexible endoscopic robotic platform.
The ESD is a more advanced and less-invasive endoscopic treatment for early gastrointestinal cancer when compared to minimally invasive surgery. It has significant advantages as an organ preservation surgical treatment, but it is technically challenging with substantial risk of perforation and bleeding.
In 2011, the research team of the university鈥檚 Faculty of Medicine had successfully performed the ESD for treatment of early gastric cancer by using the first prototype flexible endoscopic robot.
The team later further developed the robot for performing the ESD in the colorectum, namely the EndoMaster EASE system.
It consists of an independently designed flexible platform with an endoscopic imaging system, and allows the passage of two minute robotic arms to achieve tissue retraction and dissection.
The university led the world鈥檚 first clinical trial on robotic colorectal ESD using the new system in May and has shown satisfactory outcomes.
Philip Wai Yan Chiu, director of the university鈥檚 Minimally Invasive Surgical Skills Center, said six patients have been successfully treated by colorectal ESD using the new system and there was no case of perforation and the patients were able to resume a normal diet and were discharged within one or two days.
鈥淔rom our initial observation, the flexible endoscopic robotic system is a very promising armamentarium for performing ESD and treating early-stage colorectal cancer. Our clinical trial is still currently underway and we will continue to enroll suitable patients to participate,鈥 Chiu added.
