Impact of Intra-Abdominal Adhesion on Dialysis Outcome in Peritoneal Dialysis Patients

الملخص EN

Background.

Peritoneal dialysis (PD) is an increasingly popular therapeutic option for patients with advanced renal failure.

However, intra-abdominal adhesions (IAA) represent a major unsolved problem in adequate PD performance.

In this study, we investigated the role of previous abdominal surgery on the presence of subsequent IAA as well as outcomes in those patients with PD who had subsequent IAA.

Methods.

Two hundred and two patients who received continuous ambulatory peritoneal dialysis were prospectively enrolled in this study.

We compared the PD adequacy indices and outcomes for technical failure in patients with and without subsequent IAA at presentation and a minimum of 2 years of follow-up.

Results.

Subsequent IAA accounted for 19% (38/202) of patients.

Patients who had previous abdominal surgery had higher risks of subsequent IAA especially those patients who had higher mean ages (P=0.023).

PD adequacy indices including both 24-hour dialysate volume and peritoneal WCcr L/week/1.73 m2 were significantly lower in patients who had, as compared to those who did not have subsequent IAA (P=0.003 and 0.018, respectively).

Although patients who had subsequent IAA had decreased PD adequacy, the development of technical failures during PD maintenance did not show significant differences at the 2-year minimum follow-up study.

Conclusions.

Subsequent IAA is not rare, especially in high-risk patients including those with previous abdominal surgery and higher mean ages.

Although decreased PD adequacy after IAA was found, the development of technical failures was not significantly different at the 2-year minimum follow-up study.
