Abstract
Despite the lower cost, improved early survival, and preservation of the remaining kidney function, peritoneal dialysis is used by only 8.8% of the dialysis population in the USA. Intraabdominal adhesions reported in 70-90% of patients with prior abdominal surgery (PAS) reduce the peritoneal surface area and may increase the intraoperative and postoperative morbidity. The objective of this study is to evaluate the outcomes of laparoscopic peritoneal dialysis (LPD) catheter placement in patients with and without PAS. Patients who had LPD catheters placed between January 2014 and August 2016 were retrospectively reviewed. A Kaplan-Meier analysis was performed to assess the revision-free catheter survival (RFCS) and revision-assisted catheter survival (RACS) between the 2 groups. One hundred forty-two patients had had LPD catheter placed during the study time, 82 (58%) with PAS. Lysis of adhesions (LOA) was required in 26 patients (28%) with PAS. Demographics and comorbidities were similar, but more women had PAS (65% vs. 35%, P<0.001). Seventeen patients (12%) required revision, with no difference between the 2 groups. Both RFCS and RACS were similar in patients without and with PAS (P=0.38 and 0.98, respectively). RFCS was 73% vs. 64% at 1year (no PAS versus PAS) and 62% vs. 51% at 2years, whereas RACS was 84% vs. 77% at 1year (no PAS versus PAS) and 69% vs. 68% at 2years. Only 2 intraoperative complications occurred, namely a superficial liver injury and pelvic hematoma. Three complications (0.02%) occurred within 30days, namely 1 peritonitis and 2 catheter malfunctions. Overall complication rate was 25%, predominantly poor drainage (17% and 22% for PAS and no PAS, respectively), and there were no differences between the subgroups. No deaths occurred within a year of surgery during the study follow-up. LPD and LOA can be performed safely in patients with multiple PAS. When possible, LPD catheters should be part of the vascular surgery training armamentarium and offered to patients with PAS.
