The time for surgery of peritonitis associated with peritoneal dialysis

Area of Science:

• Nephrology
• Infectious Diseases
• Surgical Pathology

Background:

• Peritonitis is the primary complication of peritoneal dialysis (PD), significantly increasing morbidity, mortality, and healthcare costs.
• It is the leading cause of PD technique failure, often leading to ultrafiltration failure due to severe, prolonged, or recurrent episodes.
• Effective peritonitis management is essential to maintain the functional integrity of the peritoneal membrane.

Observation:

• The primary treatment for PD peritonitis involves antibiotic therapy, with surgical intervention typically not required.
• A critical distinction must be made between catheter-related peritonitis and secondary peritonitis stemming from visceral lesions.
• Misdiagnosing secondary peritonitis as catheter-related can lead to incorrect treatment strategies, potentially endangering patient lives.

Findings:

• Differentiating refractory or secondary peritonitis in PD patients presents significant diagnostic challenges.
• Prompt surgical exploration is indicated for refractory PD peritonitis to identify and address underlying visceral causes.
• The ultimate goal of peritonitis treatment is the preservation of the peritoneal membrane, not merely the removal or management of the dialysis catheter.

Implications:

• Accurate differential diagnosis between catheter-related and secondary peritonitis is vital for appropriate and timely treatment selection.
• Delaying surgical intervention in cases of secondary peritonitis can have severe consequences for patient outcomes.
• Preserving peritoneal membrane function through effective peritonitis management is key to the long-term success of peritoneal dialysis.
