Endoscopic ultrasound-guided celiac plexus block and neurolysis.

摘要: Endoscopic ultrasound-guided celiac plexus neurolysis (EUS-CPN) is widely used for reducing pain originating from upper abdominal organs. It mainly indicated to treat pancreatic cancer pain, but also relieve as a result of chronic pancreatitis. Real-time guidance and color Doppler imaging by EUS made the procedure easier safer, resulting in greater relief. Currently, two techniques are EUS-CPN. The classic approach, known central technique, involves injection neurolytic agent at base axis. In bilateral injected on both sides addition, EUS-guided direct ganglia (EUS-CGN) was introduced recently. Pain relief achieved EUS-CPN 70-80% patients with 50-60% those technique may be more efficient than although possibly safer. Moreover, EUS-CGN provide conventional Procedure-related complications include transient exacerbation, hypotension, diarrhea, inebriation. Although most not serious, major adverse events such retroperitoneal bleeding, abscess, ischemic occasionally occur.
