Late Peritoneal Dialysis Exit-Site Leak: A Case Report

Area of Science:

• Nephrology
• Surgical Complications

Background:

• Peritoneal dialysis (PD) is a vital treatment for kidney failure.
• Pericathether exit-site leaks are a known complication of PD.
• Distinguishing between early and late leaks is crucial for effective management.

Observation:

• Early exit-site leaks (within 30 days) are common and often resolve with conservative management.
• Late exit-site leaks are infrequent and present unique challenges.
• This report details a rare case of late leak due to unusual PD catheter trauma.

Findings:

• Early leaks can be managed by temporarily pausing or adjusting PD therapy to promote healing.
• Late leaks typically do not resolve with PD cessation alone and frequently necessitate catheter replacement.
• The case highlights a novel cause of late-onset PD catheter trauma leading to an exit-site leak.

Implications:

• Understanding the timing and cause of PD exit-site leaks guides appropriate clinical intervention.
• Prompt diagnosis and tailored management can prevent further complications and optimize PD therapy.
• This case expands the differential diagnosis for late PD exit-site leaks, emphasizing the need for thorough investigation of catheter integrity.
