Background: Our centre introduced peritoneoscopic insertion of peritoneal dialysis (PD) catheter by nephrologists as a new method in August 2009 for its potential benefits.
Aim: The aim of this study was to compare perioperative complications and catheter survival of three techniques: peritoneoscopic, surgical and radiological techniques within a single dialysis centre.
Method: This study used retrospective analysis of all PD catheter inserted from 1 August 2009 to 31 July 2013 within Counties Manukau DHB, Auckland, New Zealand.
Results: During the study period, 293 PD catheters were inserted, 84 (29%) peritoneoscopic (P), 140 (48%) surgical (S) and 69 (23%) radiological (R). Total duration of follow-up was 5848 catheter-months, with median follow-up of 17 months. There was no difference in perioperative exit-site infections and overall early infections. There was however increased overall perioperative complications in P compared with R (HR 2.08; P < 0.05), predominantly from catheter removal within 60 days. Although there was no difference observed in first catheter 1-year and overall survival between insertion techniques, there was poorer complication-free survival comparing P to S (HR 1.82, P = 0.001) but not to R. Analyses of the latter cohort of P confirmed improvement in catheter survival compared with an earlier cohort and to other insertion techniques.
Conclusion: Peritoneoscopic PD catheter insertion is demonstrated to be a suitable alternative technique. As with any new procedure, 'learning curve' effects and development of operator expertise need to be taken into consideration.

Improvement of lactic acidosis in pyruvate dehydrogenase complex deficiency using custom-made amino acid-based dialysate for peritoneal dialysis.

This case report presents a newborn with pyruvate dehydrogenase complex deficiency who developed significant lactic acidosis and acute kidney injury after birth. Peritoneal dialysis with glucose-based peritoneal dialysis fluid was initially started, but the patient had worsening hyperglycemia and lactic acidosis, likely related to excess glucose reabsorption with shunting to lactate due to the underlying metabolic disorder. As amino acid-based dialysis solution was not available in our formulary, a dialysis fluid was manually created with Vaminolact, which was commonly used in neonatal parenteral nutrition.

Background: Peritoneal fibrosis is a serious complication of long-term peritoneal dialysis (PD) and abdominal surgeries, yet effective treatments remain elusive. Given the known roles of mucosal-associated invariant T (MAIT) cells in immune responses and fibrotic diseases, we investigated their involvement in PD-induced peritoneal fibrosis to identify potential therapeutic targets.
Methods: We employed single-cell RNA sequencing (scRNA-seq) and flow cytometry to characterize the activation and function of peritoneal MAIT cells in patients undergoing long-term PD.
Co-Producing Peritoneal Dialysis Nursing Sensitive Indicators for Quality Care: A Multinational Consensus Building Design.

Background: Nursing sensitive indicators are a way of measuring aspects of patient care that are most affected by the actions of the nurse. Despite the existence of nursing sensitive indicators, these are largely not suitable to measure peritoneal dialysis nursing practice.
Objective: This project aimed to co-develop a set of peritoneal dialysis nursing-sensitive indicators.
