Core tip: The effects of endoscopic retrograde cholangiopancreatography (ERCP) on pregnant women, addressed in the recent article by Smith et al, is an interesting topic. Despite the large sample of patients investigated by the authors, strong experimental evidence on this topic is still lacking. ERCP should be performed only with a therapeutic purpose and by experienced ERCP endoscopists, preferably during the second trimester of pregnancy.
