Chyloretroperitoneum following anterior spinal surgery

Area of Science:

• Spinal Surgery
• Vascular Surgery
• Abdominal Surgery

Background:

• Anterior approaches to the lumbar spine carry a risk of lymphatic channel injury.
• Such injuries can lead to the accumulation of lymphatic fluid in the retroperitoneal space, forming a lymphocele.

Observation:

• This study reports 4 cases of postoperative retroperitoneal chylous fluid collections following anterior lumbar spine surgery.
• These collections, if large, can cause abdominal pain, bowel ischemia, and compression of adjacent organs.

Findings:

• The authors detail the lymphatic anatomy and pathophysiology relevant to this complication.
• A review of existing literature highlights the rarity and underreporting of this condition.

Implications:

• A high index of suspicion is crucial for prompt diagnosis and management of post-lumbar spine surgery lymphoceles.
• The study proposes a treatment algorithm to guide clinical decision-making for this rare complication.
