Catheter insertion techniques for improving catheter function and clinical outcomes in peritoneal dialysis patients.

Peritoneal dialysis catheter insertion techniques by the nephrologist.

Peritoneal dialysis (PD) catheter is the lifeline of PD patients, and despite the overall strength of the PD program in many countries, PD catheter survival remains the major weakness of the program. The prompt and effective implantation of the PD catheter, as well as speedy management of complications arising from catheter insertion, remains crucial for the success of the program.

Study of early complications associated with peritoneal dialysis catheters: an analysis of the New Zealand Peritoneal Dialysis Registry data

Early peritoneal dialysis catheter (PDC)-related complications are frequent and make an important contribution to long-term PD survival. We aimed to analyse the incidence and specific causes of early PDC-related complications. This study was conducted from January 2001 to December 2012, utilising the New Zealand PD Registry (NZPDR) data. The objectives of this study were to analyse the incidence and causes of PDC-related complications within 4weeks and 3months of insertion. A logistic regression analysis was conducted to analyse any demographic or clinical risk factors of early PDC-related complications. Of the 2573 PDC insertions during this period, majority 88% were surgically inserted. The number of complication within 4weeks ranged from minimum of 20% to a maximum of 34% annually, with infections and flow dysfunctions leading the causes. There has been a minor drop in the infection rates from 19 to 16% (p = 0.21), and flow dysfunction from 12 to 9% (p = 0.16), from 2001 to 2012. A reduced odds of early complication was noted in elderly individuals above 60years age, with odds ratio of (OR) of 0.73 (95% CI 0.53-0.99), while as higher odds of early complications were recorded in female gender, OR 1.41 (95% CI 1.06-1.88). Of the 10% of patients who failed to initiate PD within 90days, flow dysfunction contributed to 32%, followed by infectious and surgical causes in 16% and 15%, respectively. The median time from insertion of PDC to initiation of PD was 17days (interquartile range of 14-24days) CONCLUSIONS: Improvements in PDC insertion techniques and reduction in infection rates may result in improvements in long-term PD technique survival.

Percutaneous peritoneal dialysis catheter implantation with no break-in period: A viable option for patients requiring unplanned urgent-start peritoneal dialysis.

BackgroundUrgent-start peritoneal dialysis (PD) is applied to patients who need PD within two weeks but are able to wait for more than 48 hours before starting PD. To evaluate the usefulness of percutaneous PD catheter insertion in urgent-start PD, we reviewed the clinical outcomes of percutaneous catheter insertion with immediate start PD and surgical insertion with longer break-in time in Pusan National University Hospital.MethodsThis study included 177 patients who underwent urgent-start PD. Based on the PD catheter insertion techniques, the patients with urgent-start PD were divided into percutaneous (n = 103) and surgical (n = 74) groups. For the percutaneous group, a modified Seldinger percutaneous catheter insertion with immediate initiation of continuous ambulatory PD was performed by nephrologists.ResultsThe percutaneous group showed higher serum urea nitrogen, creatinine, and lower serum albumin compared with the surgical group (P < 0.05). Ninety-day infectious and mechanical complications showed no significant differences between the two groups. Ninety-day peritonitis in the percutaneous group was 9.7% compared to 5.4% in the surgical group (P = not significant [NS]). Major leakage was 3.9% in the percutaneous group compared to 1.4% in the surgical group (P = NS). Overall infectious and mechanical complication-free survival was not significantly different between the two groups. The percutaneous group and surgical group showed no statistical difference with respect to catheter survival over the entire observation period (P = NS).ConclusionThis study suggests that urgent-start PD can be applied safely with percutaneous catheter insertion by nephrologists with no break-in period.

Comparison of peritoneal dialysis catheter insertion techniques by nephrologists: Surgical vs blind methods.

The aim of the present study was to perform a comparative analysis of peritoneal dialysis catheter (PDC) insertion between blind and surgical methods by nephrologists. The present study enrolled 249 peritoneal dialysis patients who received first-time PDC insertion. All PDC insertions were performed using either the blind or surgical method. In our hospital during the study period, two of three nephrologists performed the blind method routinely in all eligible patients (blind group), and one of three nephrologists performed the surgical method in all eligible patients (surgical group). Catheter outcomes, including infectious or mechanical complications, functional parameters, and catheter survival, were evaluated. The numbers of patients underwent surgical or blind methods were 105 and 144, respectively. The use of systemic analgesics in the surgical group was higher than that in the blind group. The operation time was longer in the blind group than in the surgical group. The D0 level and peritoneal Kt/V were similar between the two groups. There was no significant difference in infectious and mechanical complications between the two groups. The catheter survival and intervention-free survival were similar between the two groups (P=.995 for catheter survival and P=.723 for intervention-free survival). Our study shows that catheter outcomes are similar between blind and surgical insertion techniques performed by nephrologists. These findings reveal that patients without previous major abdominal surgery would be suitable to receive any one of the two methods according to the operator-friendly technique.

Peritoneal Dialysis for Acute Kidney Injury Treatment in the United States: Brought to You by the COVID-19 Pandemic.

The coronavirus disease 2019 (COVID-19) pandemic has created unprecedented strain on health care resources in the United States. Initial reports of AKI rates from Wuhan, China ranged between 3% and 9%, although rates as high as 15% have been reported (1,2). For AKI requiring RRT, intermittent hemodialysis (HD) and continuous RRT (CRRT) have been mainstays of therapy in the United States. However, shortages in supplies, staffing, and available equipment among critically ill patients with COVID-19, particularly in the New York City area, have demanded alternative strategies such as acute peritoneal dialysis treatment for AKI (AKI-PD) that are being implemented. Here, we will review the rationale for the use of AKI-PD and describe potential advantages, criteria for patient selection, and practical considerations on the basis of initial experiences to consider when prescribing and delivering peritoneal dialysis (PD). PD was routine for AKI treatment worldwide well into the 1980s. However, by the 1990s with the development of the central venous catheter for HD and the advent of CRRT, PD became rarely used in higher-resource countries to treat adult patients with AKI (3). The utility and efficacy of PD to treat patients with AKI were re-examined after the publication of a series of articles from Brazil, including a randomized trial, demonstrating that PD provided acceptable care, was not inferior to daily HD in treating acutely ill patients with AKI in terms of patient mortality, and was associated with a shorter duration of AKI and need for RRT (4,5). These findings were confirmed in a randomized trial from Saudi Arabia comparing PD with hemodiafiltration (6). AKI-PD expanded dramatically in lower-resource countries with the advent of the Saving Young Lives Program in 2012, which promoted the use of PD because of minimal infrastructural requirements, including a lack of need for water …

United Kingdom Catheter Study – Protocol Synopsis

High-quality peritoneal dialysis (PD) catheter insertion pathways are essential for optimal access to the therapy. Dialysis outcomes are influenced by a range of patient and center-related factors, and there is a need to better understand these so that catheter insertion pathways can be better matched to individual circumstances. To examine how patient- and center-related factors influence the choice of catheter insertion pathways for a PD patient, and the impact of such factors and pathways on patient outcomes, and specifically, to compare the occurrence of and recovery from PD catheter-related adverse events and mortality in individuals who had surgical catheter insertion with those who had medical catheter insertion, and evaluate health economics. A prospective multi-center cohort study of incident PD patients at catheter insertion. This is an ancillary study nested within the International Peritoneal Dialysis Outcomes and Practice Patterns Study (PDOPPS). Patients will be recruited during a 30-month recruitment period at 45 United Kingdom (UK) renal facilities, with a minimum 12-month follow-up. A graphical Markov model will be fitted to describe the associations between patient demographics, comorbidities, and catheter insertion pathways that are not explained by center practices and their impact on the occurrence of catheter-related adverse events, and patient-reported outcomes. The model will also explore the extent to which the catheter insertion pathway is determined by the center practice patterns, accounting for patient mix. Multi-state models will compare the rate of occurrence of a PD catheter-related adverse event, recovery from this, and mortality in individuals who had surgical catheter insertion compared with those who had medical catheter insertion, accounting for competing events, and adjusting for patient and center factors. A health economics evaluation will establish which, if any, catheter insertion pathway is superior in terms of cost effectiveness. The study will provide information on which catheter insertion pathways are better according to individual characteristics and whether it is acceptable for dialysis units to rely on a single catheter insertion technique or whether they should invest in developing flexible pathways that incorporate both medical and surgical PD catheter insertion techniques.

Peritoneal dialysis catheter placement as a mode of renal replacement therapy: Long-term results from a tertiary academic institution

Peritoneal dialysis as a mode of renal replacement therapy still has not been embraced widely as an alternative to hemodialysis. Furthermore, there is marked variability in peritoneal dialysis catheter insertion techniques and perioperative management within the United States. After the publication of best-demonstrated practices for peritoneal dialysis catheter placement, the utilization of peritoneal dialysis has increased significantly at our institution. We detail the long-term success of peritoneal dialysis catheter placement after the adoption of best-demonstrated practices. Retrospective chart review was performed on all patients who underwent laparoscopic peritoneal dialysis catheter placement using the best-demonstrated practice technique from January 2005 through December 2015. Preoperative patient demographic information, intraoperative variables, 30-day morbidity and mortality, and long-term catheter durability outcomes were investigated. A total of 457 patients met inclusion criteria. Four (0.9%) patients experienced an immediate postoperative complication requiring return to the operating room. There were no perioperative mortalities. A total of 298 (65.2%) patients were available for long-term follow-up; 221 (74.2%) patients are still alive, 76 (25.6%) patients are still undergoing peritoneal dialysis, 63 (21.1%) patients transitioned from peritoneal dialysis to hemodialysis, and 88 (29.5%) patients have undergone kidney transplantation. Based on Kaplan-Meier survival plots, 30% of patients will transition from peritoneal dialysis to hemodialysis after 5.5years of peritoneal dialysis and the median time from commencing peritoneal dialysis to kidney transplantation is 5.6years. Based on our institutional data, the adoption of best-demonstrated practices should provide long-term and reliable access to the peritoneal cavity. We recommend the adoption of these techniques to facilitate long-term peritoneal dialysis catheter survival.

How I Do It: Percutaneous Image-guided Peritoneal Dialysis Catheter Insertion

Peritoneal Dialysis (PD) catheter insertion is traditionally performed using open surgical or laparoscopic techniques. The minimally invasive percutaneous PD catheter insertion techniques guided by fluoroscopy and ultrasound proved to provide comparable results in terms of catheter survival and dysfunction rates and lower incidence of catheter related peritonitis and leak. Percutaneous insertion by interventional radiologists offers more flexible scheduling and efficiency compared to surgical approaches that require operating room booking and general anesthesia. Here we report a step-by-step guide for percutaneous image-guided PD catheter insertion based on our institutional experience and previous best practice recommendations in the literature.

Role of Laproscopy in Peritoneal Dialysis Catheter Insertion

Peritoneal dialysis(PD) is regarded as a safe and effective dialysis modality for ESRD. PD catheter insertion using Laproscopic(lap) techniques has gained importance in the recent years especially in difficult and complicated cases. This review focuses on the Lap technique of PD Catheter insertion.

Catheter Insertion and Perioperative Practices Within the ISPD North American Research Consortium.

♦ In general, efforts to standardize care based on group consensus practice guidelines have resulted in lower morbidity and mortality. Although there are published guidelines regarding insertion and perioperative management of peritoneal dialysis (PD) catheters, variation in practice patterns between centers may exist. The objective of this study is to understand variation in PD catheter insertion practices in preparation for conducting future studies. ♦ An electronic survey was developed by the research committee of the International Society for Peritoneal Dialysis - North American Research Consortium (ISPD-NARC) to be completed by physicians and nurses involved in PD programs across North America. It consisted of 45 questions related to 1) organizational characteristics; 2) PD catheter insertion practices; 3) current quality-improvement initiatives; and 4) interest in participation in PD studies. Invitation to participate in the survey was given to nephrologists and nurses in centers across Canada and the United States (US) identified by participation in the inaugural meeting of the ISPD-NARC. Descriptive statistics were applied to analyze the data. ♦ Fifty-one ISPD-NARC sites were identified (45% in Canada and 55% in the US) of which 42 responded (82%). Center size varied significantly, with prevalent PD population ranging from 6 - 300 (median: 60) and incident PD patients in the year prior to survey administration ranging from 3 - 180 (median: 20). The majority of centers placed fewer than 19 PD catheters/year, with a range of 0 - 50. Availability of insertion techniques varied significantly, with 83% of centers employing more than 1 insertion technique. Seventy-one percent performed laparoscopic insertion with advanced techniques (omentectomy, omentopexy, and lysis of adhesions), 62% of sites performed open surgical dissection, 10% performed blind insertion via trocar, and 29% performed blind placement with the Seldinger technique. Use of double-cuff catheters was nearly universal, with a near even distribution of catheters with pre-formed bend versus straight inter-cuff segments. There was also variation in the choice of perioperative antibiotics and perioperative flushing practices. Although 86% of centers had quality-improvement initiatives, there was little consensus as to appropriate targets. ♦ There is marked variability in PD catheter insertion techniques and perioperative management. Large multicenter studies are needed to determine associations between these practices and catheter and patient outcomes. This research could inform future trials and guidelines and improve practice. The ISPD-NARC is a network of PD units that has been formed to conduct multicenter studies in PD.

Long-Term Outcomes of Single-Port Laparoscopic Placement of Peritoneal Dialysis Catheter

Laparoscopic insertion of peritoneal dialysis (PD) catheter has become a preferred method compared to the traditional open technique for PD catheter insertion. We retrospectively report the outcome of 1-port laparoscopic placement PD catheters in our institution. A total of 263 patients with end-stage renal disease who underwent single-trocar laparoscopic PD catheter insertion during a recent 6-year period were reviewed. Laparoscopic technique involves introducing a PD catheter over a stiff guidewire into the abdominal cavity through a 10-mm laparoscopic port. Pertinent clinical variables, procedural complications, and follow-up outcome were analyzed. There were 182 men and 81 women. The mean age was 56 years. Technical success was 95.8%. Catheter occlusion was the most common early complications (<6 months) that occurred in 4 (1.5%) patients. Late complications (> 6 months) including catheter occlusion, cuff extrusion, catheter leakage, catheter migration, infection, and hernia occurred in 5 patients (1.9%), 2 patients (0.8%), 3 patients (1.1%), 3 patients (1.1%), 6 patients (2.3%), and 4 patients (1.5), respectively. Mean follow-up time was 39 ± 18 months. Catheter survival rate at 1, 2, 3, 4, and 5 years was 96%, 94%, 90%, 85%, and 82%, respectively. Laparoscopic PD catheter implantation via a single-trocar utilizing a stiff guidewire technique is feasible and safe. This method can result in low complication and high catheter survival rate.

A novel technique of catheter placement with fibrin glue to prevent pericatheter leakage and to enable no break-in period in peritoneal dialysis

Pericatheter leakage is a catheter-related complication of peritoneal dialysis (PD). To prevent pericatheter leakage, a modified technique of PD catheter insertion with fibrin glue was performed in 19 children. At the time of PD catheter insertion, as much fibrin glue as possible was injected into the subcutaneous tissue along the tunneled segment of the catheter and then the skin was compressed. There was no occurrence of pericatheter leakage and full PD could be initiated 1 day (median) after implantation. This technique prevented pericatheter leakage completely even in smaller-weight infants and will enable initiation of full PD with no break-in period.

Laparoscopic versus open peritoneal dialysis catheter insertion, the LOCI-trial: a study protocol

BackgroundPeritoneal dialysis (PD) is an effective treatment for end-stage renal disease. It allows patients more freedom to perform daily activities compared to haemodialysis. Key to successful PD is the presence of a well-functioning dialysis catheter. Several complications, such as in- and outflow obstruction, peritonitis, exit-site infections, leakage and migration, can lead to catheter removal and loss of peritoneal access. Currently, different surgical techniques are in practice for PD-catheter placement. The type of insertion technique used may greatly influence the occurrence of complications. In the literature, up to 35% catheter failure has been described when using the open technique and only 13% for the laparoscopic technique. However, a well-designed randomized controlled trial is lacking.Methods/DesignThe LOCI-trial is a multi-center randomized controlled, single-blind trial (pilot). The study compares the laparoscopic with the open technique for PD catheter insertion. The primary objective is to determine the optimum placement technique in order to minimize the incidence of catheter malfunction at 6 weeks postoperatively. Secondary objectives are to determine the best approach to optimize catheter function and to study the quality of life at 6 months postoperatively comparing the two operative techniques.DiscussionThis study will generate evidence on any benefits of laparoscopic versus open PD catheter insertion.Trial registrationDutch Trial Register NTR2878

Dialysate leaks in peritoneal dialysis.

Dialysate leakage represents a major noninfectious complication of peritoneal dialysis (PD). An exit-site leak refers to the appearance of any moisture around the PD catheter identified as dialysate; however, the spectrum of dialysate leaks also includes any dialysate loss from the peritoneal cavity other than via the lumen of the catheter. The incidence of dialysate leakage is somewhat more than 5% in continuous ambulatory peritoneal dialysis (CAPD) patients, but this percentage probably underestimates the number of early leaks. The incidence of hydrothorax or pleural leak as a complication of PD remains unclear. Factors identified as potentially related to dialysate leakage are those related to the technique of PD catheter insertion, the way PD is initiated, and weakness of the abdominal wall. The pediatric literature tends to favor Tenckhoff catheters over other catheters as being superior with respect to dialysate leakage, but no consensus on catheter choice exists for adults in this regard. An association has been found between early leaks (< or =30 days) and immediate CAPD initiation and perhaps median catheter insertion. Risk factors contributing to abdominal weakness appear to predispose mostly to late leaks; one or more of them can generally be identified in the majority of patients. Early leakage most often manifests as a pericatheter leak. Late leaks may present more subtly with subcutaneous swelling and edema, weight gain, peripheral or genital edema, and apparent ultrafiltration failure. Dyspnea is the first clinical clue to the diagnosis of a pleural leak. Late leaks tend to develop during the first year of CAPD. The most widely used approach to determine the exact site of the leakage is with computed tomography after infusion of 2 L of dialysis fluid containing radiocontrast material. Treatments for dialysate leaks include surgical repair, temporary transfer to hemodialysis, lower dialysate volumes, and PD with a cycler. Recent recommendation propose a standard approach to the treatment of early and late dialysate leaks: 1-2 weeks of rest from CAPD, and surgery if recurrence. Surgical repair has been strongly suggested for leakage causing genital swelling. Delaying CAPD for 14 days after catheter insertion may prevent early leakage. Initiating CAPD with low dialysate volume has also been recommended as a good practice measure. Although peritonitis and exit-site infections are the most frequent causes of technical failure in peritoneal dialysis (PD), dialysate leaks represent one of the major noninfectious complications of PD. In some instances, dialysate leakage may lead to discontinuation of the technique (1). Despite its importance, the incidence, risk factors, management, and outcome of dialysate leakage are poorly characterized in the literature. We will review the limited available information on this topic in the next few sections.
