Insights
In children with biliary-type pain and low gallbladder ejection fraction (GBEF), acid-related gastrointestinal (GI) issues are common. Proton pump inhibitor (PPI) trials may resolve pain, potentially avoiding laparoscopic cholecystectomy (LC).
Area of Science:
- Pediatric Gastroenterology
- Biliary System Disorders
- Gastrointestinal Pathology
Background:
- Decreased gallbladder ejection fraction (GBEF) is linked to abdominal pain and GI diseases in children.
- Acalculous biliary-type abdominal pain in pediatric patients requires thorough gastrointestinal (GI) evaluation.
- Understanding the underlying GI pathology is crucial for effective pain management.
Purpose of the Study:
- To investigate GI tract pathology in children presenting with acalculous biliary-type abdominal pain.
- To assess the efficacy of a 2-week proton pump inhibitor (PPI) trial in alleviating pain.
- To evaluate the outcomes of laparoscopic cholecystectomy (LC) for persistent symptoms.
Main Methods:
- Pediatric patients (<18 years) with Rome III-defined biliary-type abdominal pain were enrolled.
- Upper endoscopy and proximal GI tract histologic analysis were performed.
- Patient responses to a 2-week PPI trial and subsequent LC were analyzed.
Main Results:
- Sixteen children with biliary-type pain and GBEF <35% were identified.
- Acid-related GI pathologies, including reflux esophagitis (11/16) and gastritis (3/16), were prevalent.
- Four of ten children achieved complete pain relief with PPIs, avoiding LC; nine underwent LC with four complete and four partial pain improvements.
Conclusions:
- Proton pump inhibitor (PPI) therapy shows promise as a cost-effective initial treatment for pediatric biliary-type abdominal pain.
- A significant proportion of children experienced complete pain resolution with PPIs, negating the need for laparoscopic cholecystectomy (LC).
- Laparoscopic cholecystectomy (LC) provided significant pain improvement in most cases where it was performed.
Aim:
Decreased gallbladder ejection fraction (GBEF) was reported in patients who had abdominal pain and gastrointestinal (GI) diseases. The study aims were to review pathology of GI tract in children with acalculous biliary-type abdominal pain and to evaluate the pain improvement after a 2-week trial of proton pump inhibitor (PPI) and laparoscopic cholecystectomy (LC).
Methods:
Children below 18 years of age with a history of biliary-type abdominal pain by ROME III criteria were evaluated. All underwent an upper endoscopy and their histologic findings of the proximal GI tract were reviewed. Responses to a 2-week trial of PPI and LC were analyzed.
Results:
Sixteen were identified with biliary-type abdominal pain with GBEF <35%. Endoscopic and histologic evidence of reflux esophagitis was observed in 11 children those of gastritis in 3 children. A GI pathology of these children is mostly acid-related and four of ten children experienced a complete response to PPIs and did not require LC. Nine children had LC; four had complete and four had partial pain improvement.
Conclusion:
A trial of PPIs may be cost-effective prior to considering LC in these patients since four of ten children experienced a complete response to PPIs without the requirement of LC, compared with four of nine children who improved completely.
