Title: Half-Perc surgical technique for catheter placement of peritoneal dialysis
Time: 16:45 -17:15


Dr. Yu Peng has been practicing integrated Chinese and western medicine for 15 years, majoring in the field of kidney failure and dialysis technique. She is the deputy director of the peritoneal dialysis (PD) center of Guangdong Provincial Hospital of Chinese Medicine. The novel device named “modified trocar” along with the new PD catheterization technique was first introduced by Dr. Peng in Guangdong province. By 2018, over 1000 cases of PD patients were operated by Dr. Peng, including 200 cases using modified trocar. Currently, over 600 PD patients are under regular follow-up and management in her PD center. 

Research Interest


Peritoneal dialysis (PD) catheter implantation is necessary for patients with end-stage renal disease (ESRD) to maintain continuous ambulatory PD (CAPD). We developed a half-percutaneous technique based on a modified trocar device for the placement of a PD catheter. The retrospectively evaluation of efficacy and safety of 84 cases using this technique will be presented.

All these patients received this new PD catheter implantation technique between September 2016 and October 2017 in the Guangdong Provincial Hospital of Chinese Medicine. All ESRD patients underwent successful PD catheterization with our novel technique. Neither conversion from this method to traditional open surgery nor major intraoperative complications were observed. The mean operative time was 20.8?±?4.5 min, and the incision length was 2.28?±?0.53 cm. The operative cost was CN ¥ 1762.45 (US $261), and the length of hospital stay was 7.5?±?0.58 days. One patient (1.19%) showed leakage, and one patient (1.19%) experienced bleeding 2 weeks after the surgery. Catheter dysfunction due to catheter tip migration occurred in nine patients (10.7%) 2 weeks after the procedure, and the placement of the catheter was corrected with conservative treatment. No visceral injuries or PD-related infections were observed up to 4 weeks after the catheters were implanted.

Based on the preliminary evaluation, we consider that this half-percutaneous technique for PD catheter implantation appears to be a safe, effective and feasible procedure. This technique has the advantages of reduced surgical trauma, a shorter operative time and faster postsurgical recovery. In particular, this novel technique is easy for nephrologists to perform and therefore may help to promote and popularize PD treatment.
