Project description:IntroductionOur objective was to assess whether clusters of centers with similar peritoneal dialysis (PD) catheter related practices were associated with differences in the risk of technique failure.MethodsPatients on incident PD in French centers contributing to the French Language PD Registry from 2012 to 2016 were included in a retrospective analysis of prospectively collected data. Centers with similar catheter cares practices were gathered in clusters in a hierarchical analysis. Clusters of centers associated with technique failure were evaluated using Cox and Fine and Gray models. A mixed effect Cox model was used to assess the influence of a center effect, as explained by the clusters.ResultsData from 2727 catheters placed in 64 centers in France were analyzed. Five clusters of centers were identified. After adjustment for patient-level characteristics, the fourth cluster was associated with a lower risk of technique failure (cause specific-HR 0.70, 95%CI 0.54-0.90. The variance of the center effect decreased by 5% after adjusting for patient characteristics and by 26% after adjusting for patient characteristics and clusters of centers in the mixed effect Cox model. Favorable outcomes were observed in clusters with a greater proportion of community hospitals, where catheters were placed via open surgery, first dressing done 6 to 15 days after catheter placement, and local prophylactic antibiotics was applied on exit-site.ConclusionSeveral patterns of PD catheter related practices have been identified in France, associated with differences in the risk of technique failure. Combinations of favorable practices are suggested in this study.

Project description:IntroductionHow patient, center, and insertion technique factors interact needs to be understood when designing peritoneal dialysis (PD) catheter insertion pathways.MethodsWe undertook a prospective cohort study in 44 UK centers enrolling participants planned for first catheter insertion. Sequences of regressions were used to describe the associations linking patient and dialysis unit-level characteristics with catheter insertion technique and their impact on the occurrence of catheter-related events in the first year (catheter-related infection, hospitalization, and removal). Factors associated with catheter events were incorporated into a multistate model comparing the rates of catheter events between medical and surgical insertion alongside treatment modality transitions and mortality.ResultsOf 784 first catheter insertions, 466 (59%) had a catheter event in the first year and 61.2% of transitions onto hemodialysis (HD) were immediately preceded by a catheter event. Catheter malfunction was less but infection was more common with surgical compared with medical insertions. Participants at centers with fewer late presenters and more new dialysis patients starting PD, had a lower probability of a catheter event. Adjusting for these factors, the hazard ratio for a catheter event following insertion (medical vs. surgical) was 0.70 (95% confidence interval [CI] 0.43 to 1.13), and once established on PD 0.77 (0.62 to 0.96).ConclusionOffering both medical and surgical techniques is associated with lower catheter event rates and keeps people on PD for longer.

Project description:A laparoscopic approach represents an effective alternative to open surgery in patients undergoing peritoneal dialysis (PD). In these patients, conventional thinking provides for removal of the peritoneal catheter during left colon resections because of higher risk of patient contamination and peritonitis. The present paper describes 3 cases of laparoscopic left hemicolectomy for colon cancer performed in PD patients without complications and without peritoneal catheter removal, leading to subsequent early PD resumption.Three normotype PD patients affected by early-stage sigmoid colon adenocarcinoma (T1-T2, M0, N0) underwent integrated surgical and nephrological management to reduce peritoneum stress, infective risk and postoperative complications. The day before surgery, patients were shifted to isovolumetric hemodialysis through tunneled central venous catheter. All patients underwent laparoscopic left hemicolectomy without Tenckhoff catheter removal. The postoperative period was uneventful, with concomitant antibiotic prophylaxis until the fifth day after surgery. Flushing of the PD catheter was performed twice a week postoperatively. Peritoneal dialysis was recovered 4 weeks after surgery in 2 cases with a well-maintained dialytic adequacy. One patient did not proceed to PD due to improvement of renal function after surgery.In selected PD patients, a minimally invasive surgical approach combined with careful nephrological management may represent a valid and safe strategy to treat early-stage colon cancer, avoiding PD drop-out.

Project description:Patients with end-stage renal disease (ESRD) often will ultimately require dialysis to survive. One type of dialysis is peritoneal dialysis (PD), which utilizes the vessel-rich peritoneum as a semi-permeable membrane to filter blood. In order to perform PD, a tunneled catheter must be placed through the abdominal wall and into the peritoneal space, with ideal positioning of the catheter within the most dependent portion of the pelvis, represented by the rectouterine or rectovesical space in women and men, respectively. There are several approaches to PD catheter insertion, including open surgical, laparoscopic surgical, blind percutaneous, and image-guided with the use of fluoroscopy techniques. Interventional radiology (through the use of image-guided percutaneous techniques) is an infrequently utilized resource to place PD catheters, and offers real-time imaging confirmation of catheter positioning with similar outcomes to more invasive surgical catheter insertion approaches. Although the vast majority of dialysis patients receive hemodialysis instead of peritoneal dialysis in the United States, some countries have moved towards a “Peritoneal Dialysis First” initiative, prioritizing initial PD, as it is less burdensome on healthcare facilities as it can be performed at home. In addition, the outbreak of the COVID-19 pandemic has produced shortages of medical supplies and delays in care delivery worldwide, while simultaneously generating a shift away from in-person medical visits and appointments. This shift may be met with more frequent utilization of imaged-guided PD catheter placement, reserving surgical and laparoscopic placement for complex patients who may require omental periprocedural revisions. This literature review outlines a brief history of PD, the various techniques of PD catheter insertion, patient selection criteria, and new COVID-19 considerations, in anticipation for the increased demand for PD in the United States.

Project description:IntroductionCatheter-related infections such as exit site infection (ESI) and tunnel infection (TI) are major causes of peritoneal dialysis (PD) discontinuation. For ESI/TI treatment, catheter diversion procedure (CDP) with exit-site renewal for catheter salvage presents an alternative to catheter removal. Nevertheless, CDP capability of improving PD catheter survival remains unclear.MethodsWe retrospectively reviewed our hospital patients who started PD during 2001-2019 (n=148): 33 treated for ESI/TI by CDP (CDP group) and 115 treated for ESI/TI using conservative therapy or none (non-CDP group). A "virtual discontinuation group" was designated for patients in the CDP group who had received PD catheter removal instead of CDP and who had stopped PD. Kaplan-Meier analysis and log-rank test PD were used for intergroup catheter survival comparison. Associations between clinical factors and PD discontinuation or death were examined using Cox proportional hazards regression analyses.ResultsFor patients (76% male, mean age of 61.7±13.0 years), 40 CDP were performed for 33 CDP group patients. Infection-free rates at 30 and 90 days after CDP were, respectively, 90% and 67%. The CDP group PD catheter survival rate was significantly higher than that of virtual discontinuation group (P < .01) and higher than that of the non-CDP group (P = .03). Multivariate analysis revealed independent association of serum albumin concentration (hazard ratio 0.33, 95% confidence interval 0.17-0.67), PD+HD combination therapy (hazard ratio 0.29, 95% confidence interval 0.17-0.49), and CDP (hazard ratio 0.44, 95% confidence interval 0.24-0.80) with PD discontinuation or death.ConclusionResults show that CDP may improve PD catheter survival as an effective and less-invasive surgical treatment for ESI/TI to avoid withdrawal of PD.

Project description:Background and objectivesLittle published information is available about access failure in children undergoing chronic peritoneal dialysis. Our objectives were to evaluate frequency, risk factors, interventions, and outcome of peritoneal dialysis access revision.Design, setting, participants, & measurementsData were derived from 824 incident and 1629 prevalent patients from 105 pediatric nephrology centers enrolled in the International Pediatric Peritoneal Dialysis Network Registry between 2007 and 2015.ResultsIn total, 452 access revisions were recorded in 321 (13%) of 2453 patients over 3134 patient-years of follow-up, resulting in an overall access revision rate of 0.14 per treatment year. Among 824 incident patients, 186 (22.6%) underwent 188 access revisions over 1066 patient-years, yielding an access revision rate of 0.17 per treatment year; 83% of access revisions in incident patients were reported within the first year of peritoneal dialysis treatment. Catheter survival rates in incident patients were 84%, 80%, 77%, and 73% at 12, 24, 36, and 48 months, respectively. By multivariate logistic regression analysis, risk of access revision was associated with younger age (odds ratio, 0.93; 95% confidence interval, 0.92 to 0.95; P<0.001), diagnosis of congenital anomalies of the kidney and urinary tract (odds ratio, 1.28; 95% confidence interval, 1.03 to 1.59; P=0.02), coexisting ostomies (odds ratio, 1.42; 95% confidence interval, 1.07 to 1.87; P=0.01), presence of swan neck tunnel with curled intraperitoneal portion (odds ratio, 1.30; 95% confidence interval, 1.04 to 1.63; P=0.02), and high gross national income (odds ratio, 1.10; 95% confidence interval, 1.02 to 1.19; P=0.01). Main reasons for access revisions included mechanical malfunction (60%), peritonitis (16%), exit site infection (12%), and leakage (6%). Need for access revision increased the risk of peritoneal dialysis technique failure or death (hazard ratio, 1.35; 95% confidence interval, 1.10 to 1.65; P=0.003). Access dysfunction due to mechanical causes doubled the risk of technique failure compared with infectious causes (hazard ratio, 1.95; 95% confidence interval, 1.20 to 2.30; P=0.03).ConclusionsPeritoneal dialysis catheter revisions are common in pediatric patients on peritoneal dialysis and complicate provision of chronic peritoneal dialysis. Attention to potentially modifiable risk factors by pediatric nephrologists and pediatric surgeons should be encouraged.

Project description:IntroductionBowel perforation is a rare but serious complication after peritoneal dialysis (PD) catheter insertion, which significantly increases mortality. Currently, there is no recommendation for preferring catheter insertion technique, since neither open surgical or percutaneous technique demonstrate superior outcome.Presentation of caseThis is a 78-year-old man who developed jejunal perforation during PD catheter placement, presenting with initial clear and satisfying PD fluid drainage. Bowel perforation was recognized after long dwell of PD fluid returned in yellowish color. Operative finding revealed a through and through jejunal wall perforation.ConclusionSatisfying dialysate flow and tip catheter location could not exclude accidental bowel perforation after PD catheter placement. Carefully patient monitoring is crucial in detecting postoperative complication.

Project description:IntroductionUrgent-start peritoneal dialysis (PD) in patients with newly diagnosed end-stage renal disease (ESRD) is a well-tolerated alternative to hemodialysis (HD). The primary aim of this study was to identify the demographic and clinical characteristics of ESRD patients, as well as the presurgical, surgical, and postsurgical factors associated with urgent-start PD complications.MethodsA retrospective cross-sectional observational study was performed on 102 patients with ESRD who merited urgent-start PD from January 2015 to June 2019. The primary clinical outcome measures were catheter leakage, dysfunction, and peritonitis, whereas the secondary outcomes were catheter removal, repositioning, and death. Statistical inferences were made with the χ2 or Fisher's exact test and independent samples t tests.ResultsOne hundred two subjects (65 men, 63.7%) 56.2 ± 15.1 years old were included in this study; 64 of the subjects had diabetes and hypertension (62.7%). Catheter leakage occurred in 8 patients (7.8%), catheter dysfunction in 27 patients (26.5%), and peritonitis in 14 patients (13.7%); meanwhile, catheter removal occurred in 6 patients (5.9%), catheter repositioning in 21 patients (20.6%), and death in 3 patients (2.9%). Peritonitis was associated with younger age (i.e., 47.0 ± 16.8 vs. 57.6 ± 14.4 years; P = 0.014; 95% confidence interval [CI]: 2.2-19.1; odds ratio [OR] 0.96; P = 0.018; 95% CI: 0.92-099), higher creatinine levels upon admission (i.e., 20.2 ± 9.8 vs. 14.1 ± 8.3; P = 0.014; 95% CI: -10.9 to -1.2), and heart failure (OR 4.79; P = 0.043; 95% CI: 1.05-21.88). Patients with abdominal hernia were 7.5 times more likely to have their catheter leak (OR 7.5; P = 0.036; 95% CI: 1.14-49.54). Catheter removal was associated with obesity (i.e., body mass index [BMI] of 31.6 ± 4.1 vs. 25.9 ± 4.9; P = 0.007; 95% CI: -9.8 to -1.6; OR 1.26; P = 0.013; 95% CI: 1.05-1.51) and Modification of Diet in Renal Disease glomerular filtration rate (MDRD-GFR) (i.e., 2.5 ± 0.6 vs. 3.7 ± 2.3; P = 0.003; 95% CI: 0.5-1.9).ConclusionPeritonitis was associated with younger age, higher creatinine levels upon admission, and heart failure; meanwhile, catheter removal was linked to obesity and lower glomerular filtration rate. Compared with previous reports, our study included patients in which PD was initiated shortly after catheter insertion, making the intervention a true urgent-start PD. This study contributes to the existing urgent-start PD literature by providing evidence that urgent-start PD with catheter opening within 72 hours has limited complications, making it a relatively safe option.

Project description:Revision patella tendon repairs are technically challenging, and to this point there is no gold standard with regard to treatment. Understanding how the surgeon previously repaired the tendon can be of use in the revision case. This includes a repair using anchor fixation in tunnels from the primary procedure, allograft augmentation under the retinacular layer, and application of a bioinductive implant. Technique Video Video 1 (0-0:05): Title. Video 2. (0:06-0:07): Disclosures. Video 3. (0:08-0:30): Intraoperative setup that includes both legs prepped in. Ensure the operative extremity is on a bone foam, has a tourniquet on, and x-ray machine is in the room. Video 4. (0:31-0:49): It’s critical to evaluate the primary repair. Sutures from the primary repair are seen extending from the inferior pole of the patella into the proximal portion of the tendon. Video 5. (0:50-1:10): This is a critical step in the procedure. Evaluates the patella bone tunnels from the primary repair. This needs to be thoroughly evaluated to determine if they can be used for anchor placement in the revision setting. Video 6. (1:11-1:24): Running locking sutures are placed within in the proximal aspect of the tendon. This suture will be anchored into the inferior pole of the patella using the old bone tunnels. Video 7. (2:12-2:37): Anchors are placed into the inferior pole of the patella using the old bone tunnels. The anchors are loaded using suture that was placed in the tendon. The allograft augmentation path in the retinacular layer is also viewed and showed being tied at the superior pole of the patella. Video 8. (2:38-2:52): Anchors placed within the inferior pole of the patella and the augment path under the retinacular layer. The yellow dotted layer is the path of the augment. Video 9. (1:25-1:40): A guide pin in the tibial tubercle in preparation for the allograft augmentation. This guide pin will be over-reamed. Video 10. (1:41-1:56): The allograft augment is placed through the tunnel and slide proximally. Video 11. (1:57-2:11): The graft is then placed under the retinacular layer. This is passed to the superior pole of the patella. Video 12. (2:53-3:10): Placement of the bioinductive implant over the portion of the tear.
