One-year outcomes of percutaneous continuous ambulatory peritoneal dialysis catheter insertion by nephrologists: First experience from Sri Lanka

Introduction: Continuous ambulatory peritonealdialysis (CAPD) via a catheter placed in the peritoneum is an established mode of renal replacement therapy. CAPD catheters are placed using either percutaneous or surgical techniques. Percutaneous method is less invasive and avoids the need for general anaesthesia, surgical space, and expertise. This study was conducted to measure one-year outcomes of percutaneous CAPD catheter insertions performed by a nephrology team; the first experience from Sri Lanka.Methods: We retrospectively studied 96 patients in two centers, who underwent percutaneous CAPD catheter insertion over two years with a follow-up period of minimum one year. The catheter was placed using modified Seldinger technique under local anesthesia with ultrasound guidance.Results: Majority were males (78.1%) with a median age of 56 years. Most were on haemodialysis (HD) (85.4%) prior to CAPD catheter insertion. The commonest reason for opting for CAPD was to avoid hospital visits for HD (54.2%). During the follow-up of one year, 85.4% were free of complications. Frequent non-infectious complications were catheter removal (12.5%), visceral injury (4.2%), primary insertion failure (4.2%), and catheter dysfunction (2.1%). Pre-training peritonitis was found in 2.1% with an overall peritonitis rate of 0.4 episodes per patient a year. There was no significant association between catheter-related complications and gender (p=0.68), previous abdominal surgery (p=0.54), diabetes mellitus (p=0.84), and hypertension (p=0.46). One-year catheter survival was 92%.Discussion: One-year outcomes of percutaneous CAPD catheter insertion by nephrologists were efficacious and safe with low complication rates. Hence, CAPD catheter insertion by well-trained nephrologists should be encouraged. Further studies comparing percutaneous versus surgical catheter placement are warranted.

Perioperative management of patient with pre-existing deep vein thrombosis for laparoscopic peritoneal dialysis catheter insertion: a case report

BackgroundA patient with chronic kidney disease and recurrent catheter-related thrombosis.Case presentationThe patient had femoral vein thrombosis and was scheduled for laparoscopically assisted continuous ambulatory peritoneal dialysis catheter insertion. The chief concerns during the perioperative period were the risk of pulmonary thromboembolism, limited venous access, and risk of bleeding as the patient was on anticoagulation therapy. Meticulous attention was paid to history, clinical examination, and to the ongoing treatment with regard to risk of systemic thrombosis.ConclusionsManagement was tailored according to risk of thrombosis and bleeding during perioperative period along with identification adverse events associated with anticoagulation and preparedness for management of pulmonary embolism.

Continuous ambulatory peritoneal dialysis catheter insertion by open technique: 20-year experience from a single center.

Continuous ambulatory peritoneal dialysis (CAPD) catheter placement is a part of renal replacement therapy. We describe our 20-year experience in using the open technique and assess its safety, efficacy, and outcome in the treatment of end-stage renal disease patients. In a retrospective study, we analyzed data of all patients who had a CAPD catheter placed using our open dissection technique using local anesthesia over the previous 20 years, with minimum 1 year of follow-up. Intraoperative data, postoperative data, and complications were noted. A total of 1410 cases were included in the study. The mean duration of follow-up was 72 ± 18 months (range 12-120 months). The mean operative time was 19 ± 7.5 min and mean hospital stay was 3 ± 1 days. No major intraoperative complications were noted. We observed a peritonitis rate of 0.49 episodes/patient/year. The most common reason for permanent catheter removal was refractory peritonitis in 21%, followed by flow failure in 7%, and ultrafiltration failure in 6.5%. The death-censored technical survival rate was 94.3%, 83.2%, 75.9%, 69.2%, and 60.6% patients at 1 year, 2 years, 3 years, 4 years, and 5 years, respectively. The open dissection method of peritoneal dialysis catheter insertion using local anesthesia at well-experienced center is a simple, painless, and uncomplicated procedure with excellent outcomes. Optimal exposure, judicious use of energy source, and using appropriate technique provide good technical success rate with lesser complications.

Continuous Ambulatory Peritoneal Dialysis Catheter Insertion Technique: A Comparative Study of Percutaneous versus Surgical Insertion.

Continuous ambulatory peritoneal dialysis (CAPD) is a standard renal replacement therapy, but there is a lack of consensus for catheter insertion method and type of catheter used. We retrospectively analyzed 140 peritoneal dialysis catheters (PDC) inserted in 139 CAPD patients by two methods; percutaneous (Group “P,” n = 47) and surgical mini laparotomy (Group “S,” n = 93) technique over a 39-month period, with cumulative experience of 2415 catheter-months: 745 catheter-months for Group “P” and 1670 catheter-months for Group “S.” Break-in period was shorter in Group “P” (P = 0.002) whereas primary nonfunction rate was comparable (P = 0.9). The mean catheter survival was better in Group “S” (17.95 ± 10.96 months vs. 15.85 ± 9.41 months in “P” group, P = 0.05) whereas the death-censored and overall catheter survival was comparable in both groups. PDC removal due to refractory peritonitis was also comparable. Mechanical complications were more in “P” group (P = 0.049), leading to higher catheter removal (P = 0.033). The peritonitis rates were higher in “P” group (1 episode per 24.8 catheter-months vs. 1 episode per 34.8 catheter-months in “S” group, P = 0.026) and related to a higher number of rural patients in the group (P = 0.04). Patient survival was comparable. There was no effect on episodes of peritonitis in those CAPD patients who had diabetic etiology or prior hemodialysis catheter-related sepsis, age, and PDC insertion method.

Modified technique of continuous ambulatory peritoneal dialysis catheter insertion in the pediatric population

ObjectivesTo assess whether placement of a superficial cuff deeper to the external oblique aponeurosis reduces cuff extrusion and exit site infection in peritoneal catheter insertion in children. Material and methodsIn 2013, a total of fourteen children underwent open continuous ambulatory peritoneal dialysis catheter insertion using Tenckhoff double cuffed catheters. The initial eight patients underwent a conventional technique and developed exit site infection and cuff extrusion. In six other patients, the technique was modified by placing the superficial cuff deeper to the external oblique aponeurosis. ResultsIn the former group, three patients developed cuff extrusion, whilst none developed it in the latter, modified group. ConclusionContinuous ambulatory peritoneal dialysis catheter insertion in children is associated with superficial cuff extrusion as a complication. It can be prevented by placing the cuff deeper to the external oblique aponeurosis instead of placing it in the conventional subcutaneous plane. In early experiences with this innovative technique, results have been promising. Randomized controlled trials can thus be undertaken to strengthen this finding.

Laparoscopic internal fixation is a viable alternative option for continuous ambulatory peritoneal dialysis catheter insertion

PurposeOne of the major drawbacks of peritoneal dialysis (PD) is catheter migration and dysfunction. Preventing catheter migration is one of the main concerns. We compared laparoscopic internal fixation method with open surgical method for catheter migration rates.MethodsFrom January 2008 to August 2009, PD catheters were inserted by laparoscopic fixation (LF) method in 22 patients and by open surgery (OS) in 32 patients. Clinical data were reviewed retrospectively. The frequency of migration, peritonitis, and other complications were compared. Catheter and patient survival rates were also compared.ResultsThe mean age and sex ratio were not different between groups. Mean follow-up duration was 29.1 months in LF group and 26.1 months in OS group. More patients in LF group (27.3%) had history of laparotomy than in OS group (3.1%) (P = 0.01). The mean operation time was significantly longer in LF group (101.6 ± 30.4 minutes) than in OS group (72.4 ± 26.03 minutes) (P = 0.00). The cumulative incidence of catheter migration was 65.6% in OS group and 13.6% in LF group (P = 0.00). Migration-free catheter survival was higher in LF group (P = 0.001). There were no differences in complication rates between groups. Overall catheter survival was similar (P = 0.93). Patient survival rate at 2 years was not different (P = 0.13).ConclusionLaparoscopic internal fixation of continuous ambulatory peritoneal dialysis catheter significantly reduces migration rates without any addition of complications. Also, laparoscopic technique did not incur patient morbidity or mortality despite the requirement for general endotracheal anesthesia and longer operation time. Therefore, internal fixation can be afforded safely in patients with previous abdominal surgery as either a salvage or preventive measure in patients with repeated catheter migration.
