Purpose This article evaluates the short- and long-term outcomes of percutaneous peritoneal dialysis (PD) catheters inserted by interventional radiology service and analyzes the factors that affect the sustainability of patent and functional PD catheters. Patients and Methods Retrospective single-institution study between April 2015 and February 2021. A total of 131 patients (75 males) were enrolled with mean age of 50 ± 19.6 years with an average body mass index (BMI) of 28 ± 7 kg/m2. Technical and clinical success were evaluated. Catheter-related complications were classified into mechanical and nonmechanical categories, including infectious complications. Indications for removal were analyzed. Results Technical and clinical success were 100%. The average dwelling time for the entire cohort was 497.5 ± 462.3 days. Forty-six patients (35%) were on PD at the last follow-up with an average dwelling time of 492 days. PD-related complications were reported in 79/131 (60.3%) patients, including peritonitis (40.46%; 53/131), followed by malposition/migration (12.21%; 16/131), tunnel/exit site infection (10.69%; 14/131), and dysfunction (12.21%; 16/131). The incidence of peritonitis within 30 days postinsertion was 9.43% (5/53). The average interval between insertion and migration was 100.5 ± 144.8 days (95% confidence interval, 6.9–14.4). There was a trend for a higher rate of malposition/migration in patients with higher BMI (p = 0.0561). Causes for PD catheters removal were: (1) infection-related (24.4%; 32/131), (2) renal transplant recipients (16%; 21/131), (3) mechanical complications (13.7%; 18/131), and (4) patient's preference (7.6%; 10/131). Conclusion Percutaneous PD catheter placement by interventional radiologists provides acceptable long-term outcomes and complication rates that meet the recommended standards.

This article aimed to assess the safety and effectiveness of biodegradable stents in the management of benign biliary strictures. This is a retrospective observational study that included all adult patients who had biodegradable stent placement for a benign cause of biliary stricture between July 2016 and August 2019. Nineteen patients were included. Seventeen patients had liver transplant. One patient had hepaticojejunostomy due to primary sclerosing cholangitis and one patient had iatrogenic left main bile duct occlusion. Stents were successfully deployed in all 19 patients (technical success: 100%). Patency rate was 90% (17/19) at 6 months and 80% (12/15) at 12 months. Seven patients in the study had stricture recurrence and needed reintervention with mean time to reintervention of 418 days (range: 8–1,155 days). There was one major complication due to cholangitis and sepsis, which required a treatment course with piperacillin/tazobactam for 10 days. No procedure-related pancreatitis or deaths occurred. Biodegradable stents are a safe and effective treatment option for benign biliary strictures and can achieve long-term patency without the need for reinterventions.
