Sustaining continuous ambulatory peritoneal dialysis after herniotomy.

Controversy still exists as to whether peritoneal dialysis (PD) treatment can be safely continued after herniotomy. Many nephrologists withhold PD treatment for several weeks after herniotomy for fear of dialysate leakage and hernia recurrence. Here, we report on 9 patients (2 women, 7 men) in whom herniotomy was performed for umbilical (n = 3), inguinal (n = 5), or cicatricial hernia (n = 2), or for open processus vaginalis (n = 2). Surgery was performed according to the Lichtenstein method with insertion of a polypropylene mesh and ligation of the hernia sac. In all patients, PD treatment was paused for the day of surgery and for 1-3 days postoperatively, depending on residual renal function. Over the next several days, low-volume (1.0-1.5 L), high-frequency (6 per day) exchanges were started. The patient's original PD regimen was gradually reinstated over the next 2-4 weeks. All patients recovered rapidly, with no uremia or dialysis-related complications. Particularly, no leakage and no hernia recurrence could be observed 3 months thereafter. None of the patients had to be hemodialyzed intercurrently. In conclusion, continuing a modified regimen of CAPD treatment after herniotomy seems to be safe, with excellent patient comfort.
