A proper functioning access to the peritoneal cavity is the first and foremost requirement to start peritoneal dialysis. Most commonly, peritoneal dialysis catheters are inserted using a surgical approach. Laparoscopic peritoneal dialysis catheter insertion is the recommended surgical technique because it offers to employ advanced adjunctive procedures that minimize the risk of mechanical complications. In patients with low risk of mechanical catheter complications, such as patients without prior history of abdominal surgery or peritonitis, and in patients ineligible for general anesthesia, the percutaneous approach of peritoneal dialysis catheter insertion is an alternative to surgical catheter insertion. Percutaneous insertion of peritoneal dialysis catheters can be performed by a dedicated nephrologist, interventional radiologist, surgeon or nurse practitioner under local anesthesia, either with or without image guidance using ultrasound or fluoroscopy. Several reports show similar catheter function rates, mechanical and infectious complications and catheter survival for percutaneously inserted peritoneal dialysis catheters compared to surgically inserted peritoneal dialysis catheters. This article describes the percutaneous insertion of peritoneal dialysis catheters technique adopted at Universitair Ziekenhuis Brussel since 2015. Our technique is a simple low-tech modified Seldinger procedure performed by the nephrologist and not using fluoroscopy guidance. We describe the excellent outcomes of our percutaneously inserted peritoneal dialysis catheters and offer a practical guide to set up your own percutaneous catheter insertion program.

Background: Percutaneous insertion of third-generation straight humeral nails is a recent alternative to the conventional open method. Rather than splitting, retracting and subsequently repairing the supraspinatus fibers to visualize the humeral head entry site, the percutaneous approach utilizes a cannulated awl to enter the intramedullary canal through the supraspinatus fibers without visualizing internal shoulder structures. Despite recent evidence demonstrating satisfactory outcomes in the percutaneous method, the potential for iatrogenic injury to the rotator cuff and other shoulder structures is not fully understood. Materials and Methods: We performed an anatomical study of 46 shoulders in 23 cadavers to compare damage caused to internal shoulder structures between the open and percutaneous techniques. Dimensions and morphologies of supraspinatus and humeral head perforations were recorded. Results: The percutaneous technique produced greater latitudinal tearing ( p = 0.002) and less longitudinal tearing ( p < 0.001) of muscle fibers, however there was no difference in supraspinatus hole area ( p = 0.748). The long head biceps tendon was within 3 mm of the bone entry hole in 13 (28%) shoulders, with one shoulder in the open group exhibiting full tendon transection. Conclusions: Percutaneous insertion of intramedullary nails using a cannulated awl appears to produce similar soft tissue and bone entry site morphology as compared to the conventional open technique. The percutaneous method was associated with slightly greater latitudinal tearing, however the effects of this remain to be clarified through clinical studies. External rotation should be avoided during instrumentation to reduce the risk of biceps tendon transection.

Background: Home-based peritoneal dialysis (PD) is an alternative to facility-based hemodialysis and has lower costs and greater freedom for patients with kidney failure. For a patient to undergo PD, a safe and reliable method of accessing the peritoneum is needed. However, different catheter insertion techniques may affect patient health outcomes. Objective: To compare the risk of infectious and mechanical complications between surgical (open and laparoscopic) PD catheter insertion and percutaneous catheter insertion. Design: Systematic review and meta-analysis. Setting: We searched for observational studies and randomized controlled trials (RCTs) in CENTRAL, EMBASE, MEDLINE, PubMed, and SCOPUS from inception until June 2018. Data were extracted by 2 independent reviewers based on a preformed template. Patients: Adult (aged 18+) patients with kidney failure who underwent a PD catheter insertion procedure. Measurements: We analyzed leak, malfunction, and bleed as early complications (occurring within 1 month of catheter insertion). Infectious complications (exit-site infections, tunnel infections, and peritonitis) were presented as both early complications and with the longest duration of follow-up. Methods: Random effects meta-analyses with the generic inverse variance method to estimate pooled rate ratios and 95% confidence intervals. We quantified heterogeneity by using the I2 statistic for inconsistency and assessed heterogeneity using the χ2 test. Sensitivity analysis was performed by removing studies at high risk of bias as measured with the Newcastle-Ottawa Scale and the Cochrane Risk of Bias tool. Results: Twenty-four studies (22 observational, 2 RCTs) with 3108 patients and 3777 catheter insertions were selected. Data from 2 studies were unable to be extracted and were qualitatively assessed. In the remaining 22 studies, percutaneous insertion was associated with a lower risk of both exit-site infections (risk ratio [RR] = 0.36, 95% confidence interval [CI] = 0.24-0.53, I2 = 0%) and peritonitis (RR = 0.52, 95% CI = 0.36-0.77, I2 = 3%) within 1 month of the procedure. There was no difference in mechanical complication rates between the 2 techniques. Limitations: Lack of consistency in the time periods for the various outcomes reported, risk of bias concerns with respect to population comparability, and the inability to analyze individual component causes of primary nonfunction (catheter obstruction, catheter migration, and leak). Conclusions: Our meta-analysis suggests differences in early infectious complications in favor of percutaneous insertion and no significant differences in mechanical complications compared with surgical insertion. These findings have implications on the direction of PD programs in terms of maximizing operating room resources.

OBJECTIVEIn this study the authors aimed to evaluate the rate of malposition, including pedicle breach and superior facet violation, after percutaneous insertion of pedicle screws using the coaxial fluoroscopic view of the pedicle, and to assess the risk factors for pedicle breach.METHODSIn total, 394 percutaneous screws placed in 85 patients using the coaxial fluoroscopic view of the pedicle between January 2014 and September 2017 were assessed, and 445 pedicle screws inserted in 116 patients using conventional open procedures were used for reference. Pedicle breach and superior facet violation were evaluated by postoperative 0.4-mm slice CT.RESULTSSuperior facet violation was observed in 0.5% of the percutaneous screws and 1.8% of the conventionally inserted screws. Pedicle breach occurred more frequently with percutaneous screws (28.9%) than with conventionally inserted screws (11.9%). The breaches in percutaneous screws were minor and did not reduce the interbody fusion rate. The angle difference between the percutaneous and conventionally inserted screws was comparable. Insertion at the L3 or L4 level, right-sided insertion, placement around a trefoil canal, smaller pedicle angle, and a small difference between the screw and pedicle diameters were found to be risk factors for pedicle breach by percutaneous pedicle screws.CONCLUSIONSPercutaneous pedicle screw placement using the coaxial fluoroscopic view of the pedicle carries a low risk of superior facet violation. The screws should be placed carefully considering the level and side of insertion, canal shape, and pedicle angle.

Background: Gender differences in systolic heart failure (HF) patients for the implantation of various cardiac implantable electronic devices (CIEDs) using ICD-10 have not been studied. We aim to explore the gender differences for each type of procedure. Methods: The National Inpatient Sample (NIS) 2016-2017 was used to obtain the hospitalizations with Systolic HF (ICD 10 CM codes I5020, I5021, I5022, I5023). Pacemaker/Defibrillator procedures were obtained using ICD 10 procedure codes. Demographic data were obtained using the variables provided in the NIS. All analysis was performed using SAS statistical software (9.4 Cary NC). Results: We identified 2,812,603 systolic HF hospitalizations from January 2016 to December 2017. Overall, two third of patients were male (62.9%). Table 1 elaborates on the demographics of these hospitalizations. Majority of hospitalizations were ascribed to white patient population (66% males were white & 63.2% females were white). Females were substantially higher Medicare beneficiaries (74.63% in females vs. 69.71% in males). Among the CIEDs, the males had a higher rates of procedure utilization compared to females (Table 2): Percutaneous insertion of defibrillator in right ventricle (1.6% in males vs. 1% in females); Insertion of defibrillator generator via sternotomy (1.1% in males vs. 0.7% in females); Percutaneous insertion of defibrillator lead in right atrium (1.1% in males vs. 0.7% in females); Cardiac resynchronization therapy-pulse generator via sternotomy (0.8% in males vs. 0.5% in females). Conclusion: Despite minimal differences in baseline characteristics, implantation of CIEDs appear to be underutilized in women. Further studies are required to confirm these findings and further explore gender differences.

While the gold standard for early stage lung cancers is still surgical resection, many patients have comorbidities or suboptimal lung function making surgery unfavorable. At the same time, more and more small lung nodules are being incidentally discovered on computer tomography (CT), leading to the discovery of pre-malignant or very early stage lung cancers without regional spread, which could probably be eradicated without anatomical surgical resection. Various ablative energies and technologies are available on the market, including radiofrequency ablation, microwave ablation, cryoablation, and less commonly laser ablation and irreversible electroporation. For each technology, the mechanism of action, advantages, limitations, potential complications and evidence-based outcomes will be reviewed. Traditionally, these ablative therapies were done under CT guidance with percutaneous insertion of ablative probes. Recently, bronchoscopic ablation under ultrasound, CT, or electromagnetic navigation bronchoscopy guidance is gaining popularity due to improved navigation precision, reduced pleural-based complications, and providing a true “wound-less” option.

Abstract Introduction One of the most seen neurosurgical complications is the ventriculoperitoneal (VP) shunt failure. The cause can be often due to peritoneal malabsorption of cerebrospinal fluid. The next safer alternative is to place a ventriculoatrial (VA) shunt. Various methods of access to the right atrium had been described. The percutaneous method of insertion of distal catheter using Seldinger technique is a safer alternative to open method. We describe the percutaneous insertion of distal catheter using Seldinger technique, modifications in the method, and specific tools required for the insertion. Clinical History The patient is a 22-year-old male who is a known case of tubercular meningitis with recurrent failure of VP shunt due to malabsorption at peritoneal end of catheter. During the last hospital visit, he presented with altered sensorium and computed tomography scan brain showed ventriculomegaly. He was planned for VA shunt placement. Surgical Technique The insertion of ventricular end of the catheter is similar to any other shunt placement. The internal jugular vein (IJV) was punctured using introducer needle and guide wire was placed in the IJV at the level of T6-T7 and the serial dilators passed on the guide wire for creating a track for passage of shunt catheter. The shunt catheter was passed over the guide wire to the desired vertebral level and distal shunt catheter is connected proximally to the shunt catheter in the neck. Conclusion The percutaneous insertion of distal catheter with serial dilators using Seldinger technique is a safe and effective method for VA shunt placement.
