Objective: The objective of this study was to compare the outcomes and complications of percutaneous image-guided versus laparoscopic peritoneal dialysis (PD) catheter placement techniques in the urgent-start setting. Materials and Methods: The medical records of 273 patients who had their first PD catheter between November 2012 and May 2017 were retrospectively reviewed. Patients were divided into radiologic group (n = 26) and laparoscopic group (n = 16). Descriptive and Kaplan–Meier (KM) analysis were used to compare time to first complication, time to catheter removal, and patient survival between the two groups. Complication-free and catheter removal rates at 1, 3, and 12 months were estimated from KM analysis. Results: A total of 42 patients were included in the study. The baseline demographics were similar between the two groups. In the radiologic group, the estimated 1, 3, and 12 months' complication-free rate were 100%, 94%, and 67%, respectively, which was not significantly different from 93%, 85%, and 45%, respectively, in the laparoscopic group (P = 0.543). The rate of catheter complications was not significantly different between the radiologic group (50%) and the laparoscopic group (31%) (P = 0.3382). The catheter removal rate in the radiologic group was 8, 18%, and 38% at 1, 3, and 12 months, respectively, versus 0%, 8%, and 20%, respectively, in the laparoscopic group (P = 0.298). The overall patient survival between two groups was not significantly different (P = 0.116) with estimated patient mortality of 15.4% at 12 months in the radiologic group and no deaths in the laparoscopic group. Conclusion: Image-guided percutaneously placed PD catheters have a similar complication and removal rates compared to laparoscopically placed catheters in the urgent-start setting.

Radiofrequency ablation for lung carcinomas: A retrospective review of a high-risk patient population at a community hospital p. 9
Nathan A Cornish, Sarah Kantharia, Martin Oselkin, Leah Portnow, Jay Shah, Igor Brichkov, Jason Shaw, Loren Harris, Peter Homel, Debkumar Sarkar, David Mobley, Shaun Honig, Sergei Sobolevsky
Purpose: The purpose of this study is to retrospectively evaluate the technical efficacy, safety, and treatment outcomes of percutaneous radiofrequency ablation (RFA) of lung tumors in patients not amenable to surgery at an urban community hospital. Materials and Methods: Informed consent and IRB approval was obtained. Eligible tumors were defined as those in patients deemed poor surgical candidates by multidisciplinary consensus or those refusing surgery. Response to treatment was assessed by computed tomography (CT) performed immediately postprocedure and regular intervals up to 36 months later. Complete response was measured as a 30% decrease in mean tumor diameter without evidence of contrast enhancement or tumor growth within the ablation zone as defined by the response evaluation in solid tumors. Patient demographics, technical success, postprocedure complications, and survival were assessed and compared with data available in literature. Results: Twenty-four patients with a total of 29 tumors underwent percutaneous CT guided RFA for biopsy-proven lung malignancies between 2010 and 2016. Complete response was achieved in 82% (14/17) of treated tumors in patients who complied with postprocedure imaging recommendations. Immediate postprocedure complications occurred following 27.6% (8/29) ablations with pneumothorax being the most common, 17.2% (6/29). Mean survival is 28.5 months (95% confidence interval: 19.7–37.3). Progressive disease was seen in 18% (3/17) patients. No immediate treatment mortality was found. No significant difference was found in survival in patients with multiple comorbidities as measured by the Charlson Comorbidity Index. Conclusions: RFA of lung tumors is a well-tolerated procedure with low incidence of minor complications, a good tumor response and survival benefit in selected patients in the community setting. This is a positive endorsement of the potential success of tumor RFA programs outside of the academic setting. In addition, patients with multiple comorbidities should still be considered candidates for RFA as no difference was seen in survival in patients with multiple medical comorbidities.

Effectiveness of percutaneous ethanol injection therapy compared to parathyroidectomy in the management of secondary and tertiary hyperparathyroidism p. 15
Inmutto Nakarin, Srisuwan Tanop, Kattipatanapong Thanate, Pochan Prach
Background: Secondary hyperparathyroidism (SHPT) and tertiary hyperparathyroidism (THPT) are a common complication of chronic renal failure. Percutaneous ethanol injection therapy (PEIT) has been used as alternative to surgery, but its effectiveness is inconsistent. Objectives: The objective of the study is to evaluate the effectiveness of PEIT in the management of patients with SHPT and THPT. Materials and Methods: Ninety-one patients with chronic renal failure and SHPT or THPT were treated with PEIT (n = 55) and surgery (n = 36) between January 2006 and July 2015. The medical records, imaging studies, and ablation techniques were reviewed to assess the efficacy of each treatment modality and complications. Results: Parathyroid hormone (PTH) level after treatment <160 pg/mL was used to indicate success of treatment. PEIT showed lower effectiveness compared to surgery (1.8% vs. 61.1%). There was no complication in PEIT group. Symptomatic hypocalcemia was found 11.1% in surgery group. Conclusion: PEIT in treatment of secondary and THPT was much less effective than surgery due to large nodule sizes, high levels of PTH, and multiple parathyroid nodules.

Percutaneous transhepatic biodegradable stent placement for benign anastomotic biliary strictures: Short-term outcomes of a single-institution experience p. 19
Mohammad Arabi, Bassam Alrehaili, Refaat Salman, Shahbaz Qazi, Omar Bashir, Khalid Abdullah, Mohammad Almoaiqel
Purpose: The purpose of this study was to assess the safety and effectiveness of biodegradable stents in the management of benign anastomotic biliary strictures. Materials and Methods: This retrospective study included all consecutive adult patients who underwent percutaneous biodegradable stent insertion for benign anastomotic biliary strictures that were refractory to cholangioplasty or biliary drainage-dependent or preferred stent placement to avoid long-term tube dependence. Fourteen stents were used in 12 patients (9 males) with a mean age of 53 years (range: 23–72 years). Ten patients had liver transplant (7 – choledochocholedochal anastomosis and 3 – hepaticojejunal anastomosis). Two patients had primary sclerosing cholangitis with hepaticojejunal anastomosis. The mean time since surgery was 5.5 years (6 months–16 years). Ten patients had an average of three (range: 1–6) previous sessions of biliary dilatation. Two patients initially preferred stent placement to avoid long-term tube dependence. Results: Technical and clinical success was achieved in all cases. One patient died 2 months after stent insertion because of progressive liver cirrhosis. No re-intervention was required in 8 (72%) of the remaining 11 patients at a mean follow-up time of 234 days (96–539 days). Three liver transplant patients required re-intervention at a mean time of 287 days. There were one severe procedure-related complication (cholangitis and sepsis) and one mild complication (transient septicemia). Stent migration into the bowel occurred in one case a few days after insertion, but this required no re-intervention. No procedure-related mortality occurred. Conclusion: Biodegradable biliary stent may offer a safe and effective option to avoid tube dependence in patients with benign anastomotic biliary strictures.

Multiple, bilateral renal oncocytomas: An uncommon condition managed with percutaneous cryoablation p. 23
Robert A Esposito, Jennifer Gordetsky, Soroush Rais-Bahrami, Andrew J Gunn
Multiple, bilateral renal oncocytomas are uncommon, and the management of this condition is poorly described. Here, we report a case of multiple, bilateral, biopsy-proven renal oncocytomas that were successfully managed using percutaneous cryoablation. This procedure may serve as a less invasive treatment for patients with multiple, bilateral renal oncocytomas when compared to radical or partial nephrectomy.

Portal vein hemodialysis-tunneled catheter: A case report in a pediatric patient with extensive systemic venous thrombosis p. 26
Karim A. Abd El Tawab, Dina E Sallam
We report a case of an 11-year-old child with end-stage renal disease and extensive systemic venous thrombosis including the inferior and superior vena cava. Transhepatic portal vein hemodialysis tunneled catheter was inserted after exhausting all other possible venous access through internal jugular, subclavian, femoral, and hepatic veins.
