AIM To explore and to analyze the patterns in decisionmaking by pediatric gastroenterologists in managing a child with a suspected diagnosis of functional gallbladder disorder(FGBD).METHODS The questionnaire survey included a case history with right upper quadrant pain and was sent to pediatric gastroenterologists worldwide via an internet list server called the PEDGI Bulletin Board.RESULTS Differences in decision-making among respondents in managing this case were observed at each level of investigations and management.Cholecystokinin-scintigraphy scan(CCK-CS) was the most common investigation followed by an endoscopy.A proton pump inhibitor was most commonly prescribed treating the condition.The majority of respondents considered a referral for a surgical evaluation when CCK-CS showed a decreased gallbladder ejection fraction(GBEF) value with biliary-type pain during CCK injection.CONCLUSION CCK infusion rate in CCK-CS-CS and GBEF cut-off limits were inconsistent throughout practices.The criteria for a referral to a surgeon were not uniform from one practitioner to another.A multidisciplinary team approach with pediatric gastroenterologists and surgeons is required guide the decision-making managing a child with suspected FGBD.
