Ultrasonic endoscopic abdominal cancer pain relief treatment Painful cancer in pancreatic cancer and abdominal malignancy can be relieved without the use or less use of pain medication. The ultrasonic endoscopic abdominal plexus block successfully carried out in our endoscopy center can effectively relieve the pain of advanced cancer tumors and significantly improve the quality of life of most patients. Patients with upper abdominal cancer suffer from pain due to compression, infiltration and metastasis of cancer tissue, which affects the abdominal plexus, especially pancreatic cancer has more severe pain, and patients mostly rely on painkillers to maintain their survival status. At present, some people clinically use ordinary B-ultrasound and CT-guided nerve block to relieve pain, but because of the long injection path, it is not easy to avoid the deep important organs in the abdominal cavity and difficult to locate, which makes the efficacy of treatment greatly affected. The longitudinal ultrasound endoscopic pain relief therapy used in our hospital is to inject anhydrous alcohol into the abdominal nerve plexus adjacent to the posterior wall of the cardia with a tiny puncture needle under the guidance of gastroscopic ultrasound to block the nociceptive nerves of the abdominal organs, thus providing pain relief. Since gastroscopic ultrasound is different from ordinary ultrasound, it uses a miniature ultrasound probe on the gastroscope, which can do ultrasound directly on the posterior wall of the stomach, thus being closer to the abdominal plexus, accurate judgment, short injection path, minimal damage to the adjacent tissues, and less complications and pain. At present, this method has been used in our hospital for injection pain treatment of advanced cancer pain in stomach, kidney and gallbladder, especially pancreatic cancer, with exact pain control and long pain relief time, which not only makes most cancer pain patients say goodbye to the days of repeated and large doses of pain medication, but also greatly reduces the mental pressure of patients’ families.
