The rate of PD catheter complication does not increase with simultaneous abdominal surgery.

INTRODUCTION: Children with kidney failure requiring PD catheter placement often require additional intraabdominal surgery. However, the risk of complication related to simultaneous abdominal surgery at time of catheter placement is unknown.

METHODS: Patients (0-18years) who underwent PD catheter placement (2012-2015) in the NSQIP-P database were reviewed. Complication rates between patients who underwent additional abdominal surgery at the time of PD catheter placement and those that did not were evaluated. One to one case control matching was performed for additional adjusted analysis.

RESULTS: Of 563 patients who met inclusion criteria, 82 underwent simultaneous abdominal surgery at time of PD catheter placement. Patients in the simultaneous group had a higher rate of wound contamination but there was no difference in rates of SSI, 30-day PD catheter complication, or 30-day mortality compared with the nonsimultaneous group. There was no difference when overall simultaneous abdominal surgery or gastrointestinal surgery was evaluated. In our 1:1 adjusted analysis, there was a higher rate of PD catheter complication (11.3% vs. 2.8%, p=0.049) and SSI (31.0% vs. 4.2%, p<0.001) in the nonsimultaneous group.

CONCLUSIONS: Thirty-day PD catheter complication and SSI in patients who underwent simultaneous abdominal surgery at time of catheter placement were noninferior to outcomes in the nonsimultaneous.
