Peritoneal dialysis access

OBJECTIVE: To compare the clinical outcomes between nephroscope-assisted "pulling thread" technique (NPT) and conventional open placement (OP) of catheters in peritoneal dialysis patients. MATERIALS AND METHODS: We retrospectively reviewed 97 consecutive patients undergoing either NPT (n = 57) or OP (n = 40) for peritoneal dialysis catheter placement from March 2007 to May 2015. The operation-related data, early catheter-related complications, and long-term catheter survival were analyzed...

Successful performance of peritoneal dialysis (PD) depends on a properly functioning PD catheter. Catheter malfunction remains a significant cause of technique failure, especially early in the course of therapy. Common causes of catheter malfunction include catheter displacement, omental or bowel wrapping, and fibrin clots. Less commonly, various intraperitoneal structures have been reported to lead to obstruction, including appendices epiploicae of sigmoid colon and the fallopian tube. Peritoneal dialysis catheter blockage due to fimbriae of the fallopian tube is being recognized as an important cause of catheter malfunction in females due to the increasing availability of diagnostic laparoscopy...

♦ BACKGROUND: There are no large studies that have examined ultra-short break-in period with a blind, bedside, midline approach to Tenckhoff catheter insertion. ♦ METHODS: Observational cohort study of 245 consecutive adult patients who underwent percutaneous catheter insertion for chronic peritoneal dialysis (PD) at our center from January 2009 to December 2013. There were 132 (53.9%) diabetics and 113 (46.1%) non-diabetics in the cohort. ♦ RESULTS: The mean break-in period for the percutaneous group was 2...

AIM: The aim of this study was to compare peritonitis rates, peritoneal dialysis technique survival and patient survival between patients who started peritoneal dialysis earlier than 14 days (early starters) and 14 days or more (delayed starters) after insertion of a Tenckhoff catheter. METHODS: Observational analysis was performed for all patients who underwent insertion of a Tenckhoff catheter at Far Eastern Memorial Hospital between 1 January 2006 and 31 December 2012...

BACKGROUND: Using a proper laparoscopic trocar for making a downward rectus sheet tunneling (RSHT) during the implementation of peritoneal dialysis (PD) catheters leads to a longer survival of catheter and less catheter dysfunction. As no specific laparoscopic trocar has been invented for insertion of PD catheters, we designed a new trocar. In this article, we describe specifications of our new invented trocar for the first time. We will describe our experience with it in our patients as well...

BACKGROUND: We present the unusual complication of peritoneal dialysis (PD) catheter dysfunction in a patient who developed a retroperitoneal hematoma following an endoscopic procedure and review the existing literature regarding this rare complication. CASE REPORT: A 60-year-old man with end stage renal disease presented with PD catheter dysfunction. Computed tomography scan of his abdomen showed a large left retroperitoneal hematoma. He underwent a diagnostic laparoscopy and PD catheter revision...

UNLABELLED: ♦ BACKGROUND AND OBJECTIVES: Catheter-related infection, namely exit-site infection (ESI) and peritonitis, is a major infectious complication and remains a main cause of technique failure for patients receiving peritoneal dialysis (PD). Topical application of antibiotic cream might reduce catheter-related infection but emergence of resistant or opportunistic organisms could be a concern. Optimal topical agents and regimens remain to be determined...

BACKGROUND: The purpose of this study was to review surgical outcomes after elective placement of peritoneal dialysis (PD) catheters in children with end-stage renal disease. METHODS: Children with PD catheters placed between February 2002 and July 2014 were retrospectively reviewed. Outcomes were catheter life, late (>30days post-op) complications (catheter malfunction, catheter malposition, infection), and re-operation rates. Comparison groups included laparoscopic versus open placement, age<2, and weight<10kg...

OBJECTIVE: The objective of this study is to compare the catheter-related complications as well as catheter survival between laparoscopic and traditional surgery in peritoneal dialysis catheter insertion. RESULTS: Five randomized controlled trials and 11 cohort studies were identified. Meta-analysis showed laparoscopic catheter is superior to traditional surgery in terms of controlling catheter migration (OR 0.17, 95% CI 0.08-0.33; p < 0.00001) and catheter survival rate (1-year survival rate: OR 3...

To evaluate the efficacy our new, three-cuff peritoneal dialysis (PD) catheter, with the low-entry technique and to study its impact on catheter survival and mechanical and infectious complications, we prospectively used it in 36 incident PD patients and compared the results with those of conventional double-cuff PD Tenckhoff catheters with the classic approach used in 37 patients. The study was carried out at our university hospital over a period of 18 months. At the end of the study, significantly higher survival rate was observed with the use of new catheter compared with the conventional two-cuff Tenckhoff catheter, 91...

Interventional nephrologists and radiologists place peritoneal dialysis catheters using the percutaneous fluoroscopic technique in both the inpatient and outpatient setting. Nephrologists caring for such patients may have to diagnose and manage the complications resulting from these procedures. Abdominal pain can occur following peritoneal dialysis catheter placement when the local and systemic analgesia wears off. However, abdominal pain with hypotension is suggestive of a serious complication. Bleeding into the abdomen and perforation of the colon or bladder should be considered in the differential diagnosis...

Tenckhoff catheter placement is a well-established procedure to facilitate continuous ambulatory peritoneal dialysis (CAPD) in end-stage renal disease (ESRD) management. Catheter malposition is a possible cause of catheter malfunction. Options to deal with early malfunction are re-exploration, omentectomy, repositioning, or new catheter placement. Technical malpositioning can be dealt with early, with minimal morbidity and cost. Here we report a case of a CAPD catheter accidentally placed preperitoneally which was salvaged using videolaparscopy...

Extended catheters with an upper abdominal exit-site (UAE) are reportedly associated with a lower incidence of peritoneal dialysis (PD)-related infections. However, little information about the optimal peritoneal catheter configuration for UAE is available. In this nonrandomized multicenter trial, 147 consecutive cases of a UAE involving either a conventional straight (CS; 80 cases) or extended swan-neck catheter (SN; 67 cases) were analyzed to compare exit-site and tunnel infections (ESTI), peritonitis, and catheter survival...

BACKGROUND: In the last few years, peritoneal dialysis (PD) catheter placement techniques and outcomes have become important because of the growing population of PD patients. Although there are a growing number of catheters placed by the minimally invasive Y-TEC peritoneoscopic technique, there are still limited data on outcomes for these catheters, especially those placed by a surgeon. We aimed to conduct a retrospective study of our experience with PD catheters placed by the Y-TEC peritoneoscopic technique in our institution...

Peritoneal dialysis (PD) is often complicated by catheter dysfunction. We designed a PD catheter implantation technique to reduce catheter dysfunction. Between June 2008 and 2012, 89 patients with end-stage renal disease were enrolled into a prospective study and randomly assigned to receive traditional catheter implantation by open surgery (n = 41) or vertical tunnel-based low-site PD catheter implantation (n = 48). Both procedures used Baxter straight double-cuffed Tenckhoff catheters. The novel implantation technique involves a low-site (7 cm above the midpoint of the pubic symphysis), individually tailored intra-abdominal segment, and increased vertical subcutaneous tunnel...

UNLABELLED: ♦ BACKGROUND: 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...

UNLABELLED: ♦ BACKGROUND: Conventional management for peritoneal dialysis (PD)-related infectious and mechanical complications that fails treatment includes catheter removal and hemodialysis (HD) via a central venous catheter with the end result that the majority of patients will not return to PD. Simultaneous catheter replacement (SCR) can retain patients on PD by avoiding the scenario of staged removal and reinsertion of catheters. The aim of this study was to evaluate a protocol for SCR without interruption of PD...

OBJECTIVE: 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. METHODS: 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. RESULTS: There was no occurrence of pericatheter leakage and full PD could be initiated 1 day (median) after implantation...

Clostridium difficile is one of the most common nosocomial pathogens and the cause of pseudomembranous colitis in cases of prior antimicrobial exposure. Extraintestinal manifestations of C. difficile are uncommon and rarely reported. We report the first successfully treated case of catheter-related C. difficile peritonitis in a patient undergoing peritoneal dialysis.
