Recently, the Department of Hepatobiliary Surgery of the First Affiliated Hospital of Xi'an Jiaotong University successfully performed endoscopic pulsed electric field tumor ablation for a patient with locally advanced pancreatic cancer. It was confirmed by scientific and technological novelty that this operation is the world's first endoscopic pulsed electric field tumor ablation operation.

Experts said that the smooth development of this innovative medical technology marks a major breakthrough in the field of innovative endoscopic surgery technology in my country, and is expected to provide a new method for the diagnosis and treatment of hepatobiliary and pancreatic tumors.

According to reports, the first surgical patient was a patient with locally advanced pancreatic cancer, who lost the opportunity for radical surgery. At the same time, due to obstructive jaundice and underlying diseases such as diabetes, the general condition was poor, it was difficult to tolerate chemotherapy, and conventional treatment methods could not Effectively carry out. According to the patient's condition, after preoperative discussion and doctor-patient communication, the medical team finally performed endoscopic retrograde cholangiopancreatography + endoscopic pulsed electric field tumor ablation + biliary stent implantation for the patient. Thanks to the high energy density of the pulsed electric field, the pulsed ablation process only takes about 100 seconds, and the average temperature of the ablation zone is 40°C.

It is understood that compared with the traditional method of puncture ablation using needle electrodes, endoscopic pulsed electric field ablation can better attach the ablation electrodes to the tumor tissue growing in the cavity, and greatly improve the focusing ability of pulse energy in the local tumor , significantly improve treatment efficacy, reduce surgical trauma, avoid tumor spread along the needle tract or complications such as bleeding and tube wall perforation, and also reduce the difficulty of surgery and the learning curve for doctors. In addition to being used in the treatment of hepatobiliary and pancreatic tumors, endoscopic pulsed electric field ablation also has broad application prospects in the fields of gastrointestinal, respiratory, urinary and metabolic diseases.

According to the hospital, the patient's vital signs were stable after the operation, the bile drainage was smooth, and the recovery was smooth.
