Insights
Chylous ascites, a rare complication after pediatric choledochal cyst surgery, was successfully treated with somatostatin. This finding offers a new therapeutic option for managing similar post-operative cases.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Clinical Case Reports
Background:
- Choledochal cysts are congenital dilations of the bile ducts.
- Surgical excision with Roux-en-Y hepaticojejunostomy is the standard treatment.
- Postoperative complications can include fluid collections, such as chylous ascites.
Observation:
- A pediatric patient developed chylous ascites two weeks post-operatively after choledochal cyst excision.
- Initial management with fasting was unsuccessful in resolving the chylous ascites.
- Intravenous somatostatin administration was initiated for treatment.
Findings:
- Intravenous somatostatin effectively resolved the chylous ascites in this pediatric patient.
- No significant adverse side effects were observed during somatostatin therapy.
- This represents the first reported case of successful somatostatin treatment for post-choledochal cyst excision chylous ascites in children.
Implications:
- Somatostatin is a potential therapeutic agent for managing pediatric postoperative chylous ascites.
- This case highlights the utility of somatostatin in challenging surgical complications.
- Further research may explore somatostatin's role in similar gastrointestinal surgical scenarios.
Abstract:
We report a case of chylous ascites developing 2 weeks after excision of a choledochal cyst with a Roux-en-Y hepaticojejunostomy. Despite the failure of the initial attempts to resolve the chylous ascites by fasting, subsequently, we successfully treated the patient's chylous ascites with intravenous somatostatin. No obvious adverse side effects occurred during the use of somatostatin. To the best of our knowledge, this is the first report of chylous ascites after choledochal cyst excision in children, which was successfully treated with somatostatin. Somatostatin may be considered as a therapeutic option of managing pediatric postoperative chylous ascites.
