Management and Outcomes for Peritoneal Dialysis Patients Diagnosed with Abdominal Hernias.

Background/objectives: The success of peritoneal dialysis is highly dependent on the integrity of the abdominal wall. Therefore, routine examination and treatment of abdominal hernias can prevent peritoneal dialysis (PD) failure, discontinuation, and conversion to hemodialysis. In this present study, we present our examination protocol for patients proposed for PD and our attitude in treating parietal defects in patients on peritoneal dialysis.

Objectives: highlight whether PD is a risk factor for the occurrence of ventral hernias, the relationship between associated pathologies and the occurrence of hernias and the need for an HD switch in the postoperative period.

Methods: Between January 2016 and December 2022, a group of 133 patients proposed for insertion of a PD catheter were evaluated according to the protocol established by our hospital. Routine examination for the diagnosis of abdominal hernias and repair before starting the DP is part of the procedure. We included patients with a 3 year minimum follow-up after insertion and evaluated the incidence of parietal defects that appeared during PD treatment.

Results: Nine patients were diagnosed and operated on for abdominal hernia before starting peritoneal dialysis and none of them had a recurrence of hernia during PD. Twelve patients were diagnosed with abdominal hernias during dialysis treatment (9% incidence) and the median length of time at which parietal defects occur during PD is 12.5 months [range 2-48]. Median BMI is 27.12 [range 22.3-31.24], with a female-male ratio of 2:1 Five patients were transferred to HD, three permanently and two patients temporarily. No patient abandoned PD treatment due to the presence of an abdominal parietal defect.

Conclusions: Diagnosis of ventral hernias prior to the time of catheterization for PD leads to a decrease in the incidence of parietal defects during PD and is mandatory in patients who are candidates for PD. Open alloplastic surgical procedures are safe procedures with a low recurrence rate in PD patients. The postoperative continuation of PD is feasible but the decision is to be made by the multidisciplinary team and individualized for each patient.
