Effect of Celiac Plexus Block on Gastric Emptying and Symptoms Caused by Gastroparesis

NCT02420925 · Status: WITHDRAWN · Phase: NA · Type: INTERVENTIONAL

No results posted yet for this study

Summary

The investigators hypothesize that in patients with gastroparesis, gastric emptying will improve with celiac plexus block. By improving gastric emptying, symptoms related to gastroparesis including nausea, vomiting, bloating, abdominal pain, and weight loss, will also improve.

In order to study this hypothesis, the investigators will enroll patients with gastroparesis who are non-responsive to the current treatments available. Patients will fill out a questionnaire to assess the severity of their symptoms then undergo Ansar testing (a non-invasive test) to measure their autonomic function respectively. Then, patients will undergo a celiac plexus block which is performed via an upper endoscopy. One week after the procedure, patients will be asked to undergo a gastric emptying study as well as repeat the Ansar testing to evaluate for any improvement in the gastric emptying and autonomic function respectively. Patient will be asked to repeat the questionnaire, one, two, three, and eight weeks after their procedure.

PROCEDURE

Celiac Plexus Block

Patients will undergo celiac plexus block via upper endoscopy with endoscopic ultrasound guidance. Injections will be performed using 0.75% bupivicaine and 40mg/ml of triamcinolone, ideally 1ml each directly into the celiac ganglia. If no ganglia is identifiable, then the injection will be performed into the celiac space, located at the take off of the celiac artery from the aorta.
