We read with enormous interest the study by Kamal et al.1 For the past two decades, dispute on the carcinogenic effects of PPI has remained. In this retrospective study using nationwide registries, long-term use of PPIs was identified to be associated with increased risks of gallbladder, intrahepatic and extrahepatic bile duct cancers.
