ETOH, ethanol alcohol; CR, complete response; PR, partial response; AE, adverse event; RCT, randomized clinical trial.
The overall % of AEs described here represents the sum of AEs reported in corresponding studies (in parentheses), focusing on the two most common AEs reported: abdominal pain and pancreatitis. However, based on reported study results, it cannot be determined whether AE categories overlapped (e. g., whether a patient documented with pancreatitis also counted toward the reported AE rate for abdominal pain). Other less commonly reported AEs include intracystic bleeding (26), splenic vein obliteration (21), hyperamylasemia (20), gastric wall cyst (27), and peritonitis (27)
In this study, 23 % of patients undergoing saline lavage and a second ETOH lavage had CR, 33 % undergoing ETOH lavage twice had CR, and 75 % undergoing a single ETOH lavage had CR[ 3] The published results [12] are from a smaller sample (N = 10; ETOH arm: 75 % CR, 20 % AEs; ETOH-free arm: 67 % CR, 0 % AEs), but the final randomized controledl trial is listed at the bottom (8).
