BackgroundPeritoneal dialysis (PD) is an important home-based dialysis modality for patients with end-stage kidney disease (ESKD). The initiation of PD requires timely and skilled insertion of a Tenckhoff catheter (TC). At most centres, TCs are inserted laparoscopically by surgeons under general anaesthetic. This requires access to increasingly scarce surgical, anaesthetic and hospital inpatient resources. Radiological insertion of TCs performed as a day procedure under local anaesthetic allows for easier access to the TC insertion with reduced resource requirements. We report our 1-year experience following the introduction of this technique to our PD programme.MethodsThis is a retrospective review of the outcomes for all patients who had TCs inserted radiologically (percutaneously with the assistance of ultrasound and fluoroscopy) over the 12-month period from December 2011 to December 2012. Relevant patient demographics collected included age, gender, body mass index (BMI), previous abdominal surgery and cause of ESKD. Extended details of the insertion procedure were also obtained including length of stay, early complications and time to first use of the catheter for PD.ResultsThirty Argyle™ Swan Neck TCs were inserted under radiological guidance during the study period. The mean age of patients was 56 (SD ± 14). The male-to-female ratio was 2:1. The mean BMI was 25.7 (SD ± 4.8). PD was the initial dialysis modality in 22 (73%) patients. Of the 30 patients, 14 (46.7%) had previously undergone extraperitoneal abdominal surgery. All catheters were inserted successfully as day cases except four patients (13.3%) who had catheters inserted during an inpatient hospital admission. Most catheters were not accessed for a minimum of 10 days to reduce the chance of exit site leakage, in two cases the catheters were used within 5 days without complication. There were no cases of peritonitis or exit site infection during the observation period. Catheter migration occurred in four patients (13.3%) but only one required surgical intervention. Minor pain issues were noted in six patients (20%) and bleeding around the exit site requiring suturing in two patients (6.7%). The introduction of this technique at our institution saw a 67% increase in the number of patients performing PD.ConclusionsRadiological insertion of TCs for PD provided improved access to catheter insertion in a timely manner with reduced resource requirements. Over the 12-month observation period we noted a high technical success rate with very few complications. Our study supports radiological insertion of TCs under local anaesthetic as a viable alternative to catheter insertion in theatre under general anaesthetic. The relative ease of radiological TC insertion has resulted in a significant increase in patient uptake of PD at our centre.
Various methods of peritoneal dialysis (PD) catheter insertion are available. The purpose of this study was to evaluate a percutaneous insertion technique using ultrasound (US) and fluoroscopy performed under conscious sedation and as day case procedure. Data of 87 percutaneous inserted dialysis catheters were prospectively collected, including patients' age, gender, body mass index, history of previous abdominal surgery and cause of end stage renal failure. Length of hospital stay, early complications and time to first use were also recorded. Institutional review board approval was obtained. A 100% technical success rate was observed. Early complications included bleeding (n = 3), catheter dysfunction (n = 6), exit site infection (n = 1) and exit site leakage (n = 1). All cases of catheter dysfunction and one case of bleeding required surgical revision. Median time of follow-up was 18 months (range 3-35), and median time from insertion to first use was days 14 (1-47). Of the 82 patients who started dialysis, 20 (23%) ceased PD at some stage during follow-up. Most frequently encountered reasons include deteriorating patient cognitive or functional status (n = 5), successful transplant kidney (n = 4) and pleuro-peritoneal fistula (n = 4). Sixty-two (71%) PD catheter insertions were performed as day case. The remaining insertions were performed on patients already admitted to the hospital. Percutaneous insertion of dialysis catheter using US and fluoroscopy is not only safe but can be performed as day case procedure in most patients, even with a medical history of abdominal surgery and/or obesity.
The burden of neurocognitive impairment (NCI) in patients receiving maintenance dialysis represents a spectrum of deficits across multiple cognitive domains which are associated with hospitalisation, reduced quality-of-life, mortality and forced decision-making around dialysis withdrawal. Point prevalence data suggests that dialysis patients manifest NCI at rates 3-5 fold higher than the general population with executive function the most This article has been accepted for publication and undergone full peer review but has not been through the copyediting, typesetting, pagination and proofreading process, which may lead to differences between this version and the Version of Record.

The unique physiology of the renal failure state and maintenance dialysis appears to drive an excess of vascular dementia subtype compared to the general population where classical Alzheimer's disease predominates. Despite the absence of evidence based cost-effective therapies for NCI, detecting it in this population creates opportunity to proactively personalise care through education, supported decision making and targeted communication strategies to cover specific areas of deficit and help define goals of care. This review discusses NCI in the dialysis setting, including developments in the definition of neurocognitive impairment, dialysis-specific epidemiology across modalities, screening strategies and opportunities for dialysis providers in this space.
A 67-year-old man developed Serratia marcescens peritonitis within a week of commencing peritoneal dialysis. Dialysate cultures isolated multidrug-resistant S. marcescens, which was treated with intraperitoneal meropenem. This unusual case highlights the problem of multidrug-resistant peritoneal dialysis infections and the potential viability of intraperitoneal meropenem as ambulatory peritonitis therapy.
