Laparoscopy to Evaluate Scrotal Edema During Peritoneal Dialysis

Abstract

Diagnostic laparoscopy was found to be helpful in confirming the source of acute scrotal edema in patients on continuous ambulatory peritoneal dialysis.

Abstract

Background:

Acute scrotal edema is an infrequent complication in patients who undergo continuous ambulatory peritoneal dialysis (CAPD), occurring in 2% to 4% of patients. Inguinal hernia is usually the cause, but the diagnosis is sometimes confusing. Imaging modalities such as computed tomographic peritoneography are helpful but can be equivocal. We have used diagnostic laparoscopy in conjunction with open unilateral or bilateral hernia repair for diagnosis and treatment of peritoneal dialysis (PD) patients with acute scrotal edema.

Technique and Cases:

Three patients with acute scrotal edema while receiving CAPD over the span of 7 years had inconclusive results at clinical examination and on diagnostic imaging. All patients underwent diagnostic laparoscopy that revealed indirect inguinal hernia, which was concomitantly repaired using an open-mesh technique.

Results:

Diagnostic laparoscopy revealed the etiology of the scrotal edema 100% of the time, with no complications, and allowed concomitant repair of the hernia. One patient had postoperative catheter outflow obstruction, which was deemed to be unrelated to the hernia repair.

Conclusion:

Diagnostic laparoscopy is helpful in confirming the source of acute scrotal edema in CAPD patients and can be performed in conjunction with an open-mesh repair with minimal added time or risk.
