Abstract
BACKGROUND: Coeliac plexus block (CPB) is a management option for pain control in chronic pancreatitis. CPB is conventionally performed by percutaneous technique with fluoroscopic guidance (PCFG). Endoscopic ultrasound (EUS) is increasingly used for CPB as it offers a better visualization of the plexus. There are limited data comparing the two modalities.
AIM: To compare the pain relief in chronic pancreatitis among patients undergoing CPB either by PCFG technique or by EUS guided technique.
METHODS: Chronic pancreatitis patients with abdominal pain requiring daily analgesics for more than 4 weeks were included. Fifty six consecutive patients (41 males, 15 females) participated in the study. EUSG-CPB was performed in 27 and PCFG-CPB in 29 patients. In both the groups, 10 mL of Bupivacaine (0.25%) and 3 mL of Triamcinolone (40 mg) were given on both sides of the coeliac artery through separate punctures.
RESULTS: Pre and post procedure pain scores were obtained using a 0-10 visual analogue scale. Improvement in pain scores was seen in 70% of subjects undergoing EUS-CPB and 30% in Percutaneous- block group (P = 0.044).
CONCLUSIONS: EUS-guided coeliac block appears to be better than PCFG-CPB for controlling abdominal pain in patients with chronic pancreatitis.
