PREVENTION OF POST-ERCP PANCREATITIS IN HIGH-RISK PATIENTS

Aim. To study the efficacy of thoracic epidural analgesia (TEA) for the prevention of post-ERCP pancreatitis in high-risk patients. Materials and methods. A parallel, blinded, randomized study. The first (TEA group) group included patients (n = 98) in whom thoracic epidural analgesia was used during endoscopic transpapillary interventions (ETI), the second (OAI group) group included patients (n = 97) in whom opioid analgesics and indomethacin (per rectum). Results. The study showed that acute pancreatitis was diagnosed significantly less frequently in patients with the TEA group than in patients with the OAI group (p = 0.0135). If in the TEA group post-ERCP pancreatitis (PEP) was verified in 3.1% (3/98) patients, in the OAI group — in 12.4% (12/97) patients. When TEA was used in high risk patients of developing post-ERCP pancreatitis, its incidence decreased from 23.3% (10/43) to 4.4% (2/46) observations (p = 0.0095). Conclusion. The use of TEA is an effective and justified method of prevention in patients at high risk of developing post-ERCP pancreatitis. In patients with a low risk of developing this complication, the use of TEA is inappropriate due to the invasiveness of the method.
