A standardized technique of laparoscopic placement of peritoneal dialysis catheter with omentectomy and closure of patent processus vaginalis: a 3-in-1 minimally invasive surgical approach in children
Journal of Pediatric Urology(2020)
摘要
Background
Omental wrapping is a common cause for catheter failure in children on peritoneal dialysis (PD). Previous studies are conflicting in the benefits of omentectomy.
Methods
We conducted a retrospective study comparing children who underwent PD catheter placement by a standardized laparoscopic three-in-one technique (lap3-in-1) from 2013 to 2018 versus a historical control cohort by open surgery without omentectomy. Lap3-in-1technique combined catheter placement with well-defined indication and extent of omentectomy, and closure of any patent processus vaginalis (PPV).
Results
There were 33 and 32 children in the lap3-in-1 and control cohorts respectively. 4/33(12.1%) in lap3-in-1 had reoperations for catheter failures which equated 1 reoperation per 144 catheter months. No reoperations were performed in lap3-in-1 cohort for omental wrapping or inguinal hernia, compared with 13/32 (41%; p < 0.001) and 5/32 (16%; p = 0.02) in the control cohort. Kaplan Meier survival curves showed significantly longer catheter life in the lap3-in-1 cohort (p < 0.001). In multivariate analysis by the COX proportional hazards model, the lap3-in-1 approach had significantly reduced risk of reoperation for catheter failure (HR 0.11; 95% CI: 0.04–0.31; p < 0.001).
Conclusions
The lap3-in-1 technique is effective in selecting those children who would benefit from omentectomy, and avoiding a second operation for inguinal hernia which develops after PD.
