Insights

Chylous ascites (CA), a rare condition with triglyceride-rich fluid, can occur after abdominal surgery. This case highlights postoperative CA following median arcuate ligament syndrome decompression.

Area of Science:

  • Gastroenterology
  • Surgical Complications

Background:

  • Chylous ascites (CA) involves triglyceride-rich peritoneal fluid, with malignancy, cirrhosis, and surgical trauma as common causes in adults.
  • No established clinical guidelines exist for managing chylous ascites.

Observation:

  • An 18-year-old female presented with abdominal pain and distention post-median arcuate ligament syndrome (MALS) decompression.
  • Computed tomography revealed significant ascites; paracentesis confirmed milky, triglyceride-rich fluid.
  • The patient's recent MALS decompression surgery was identified as the cause of acute CA.

Findings:

  • Postoperative chylous ascites occurred as a complication of median arcuate ligament syndrome decompression.
  • Ascitic fluid analysis confirmed high triglyceride levels, indicative of chylous ascites.

Implications:

  • This case underscores the varied etiologies of ascites, including surgical complications.
  • Emphasizes the critical role of thorough patient history and physical examination in diagnosing ascites.
  • Highlights the need for considering surgical complications in the differential diagnosis of chylous ascites.
