Clinical Application of Peritoneal Dialysis Catheterization without Capsular Puncture Technique

To summarize the advantages of peritoneal dialysis (PD) catheters without capsular puncture (only one pneumoperitoneum needle) puncture technique conducted by our center.

The study examines the clinical data of PD patients (including the general situation of patients, intraoperative and postoperative characteristics, and complications) undergoing pneumoperitoneum needle catheterization from January 2019 to May 2021 in the Department of Nephrology at the First Affiliated Hospital of Hebei North University (the largest peritoneal dialysis center in Zhangjiakou).

A total of 153 surgical cases were collected. There were 91 males and 62 females. The mean (± standard deviation) age was 56.1 ± 18.6 years, and the mean (± standard deviation) follow-up time was 16.7 ± 8.2 months. The average operation time was 30.33 minutes with a standard deviation of 14.80 minutes. The length of abdominal incision is 2.38 ± 0.42 cm, and the blood loss was about 26.3 ± 9.2 ml, including 2 cases of laparoscopic reposition of drift tube, 0 case of pipe blockage, 3 cases of fluid leakage, 1 case of peritoneal dialysis catheter tunnel infection, 4 cases of outlet infection, 12 occurrences of peritonitis, 121.3 patient months in peritonitis, and 0 times in omentum wrapping without bladder injury, incisional hernia, or intestinal injury.

Relative to open operation, the peritoneal dialysis (PD) catheters with pneumoperitoneum needle puncture technique has the following advantages: simpler operation, shorter operation time, less bleeding, less injury, less complications, and higher safety. Moreover, there are no additional costs compared with open operation. Thus, the technique is recommended for clinical applications.
