[PMID: 38101131 DOI: 10.1016/j.amjoto.2023.104146] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Accepted: 12/03/2023] [Indexed: 12/17/2023]
Abstract
PURPOSE Percutaneous dilatational tracheostomy (PDT) is the preferred method for managing long-term ventilator-dependent patients in ICUs. This study aimed to evaluate the association between preprocedural screening (ultrasound Doppler [USD] or computed tomography [CT]) for major neck blood vessels and complications in ICU patients undergoing PDT. MATERIALS AND METHODS This was a retrospective cohort study of patients who underwent PDT between 2012 and 2023 at a tertiary referral center. We performed a multivariable analysis and created a propensity-matched cohort. The primary outcome was bleeding within the first seven days after PDT. Secondary outcomes included early and late PDT complications and PTD-related mortality. RESULTS A total of 1766 consecutive critically ill patients hospitalized at a tertiary academic hospital were evaluated for PDT. Of these, 881 (49.9 %) underwent only physical examination before PDT, while 885 (50.1 %) underwent additional imaging (CT/USD). A higher proportion of patients in the imaging group were referred to open surgery due to suspected major blood vessels interfering with the procedure (6.2 % vs. 3.0 %, p = 0.001). Among the 1685 patients who underwent PDT, there was no significant difference in the rate of early bleeding between the physical examination group and the imaging group (4.6 % vs. 6.3 %, p = 0.12). Similarly, the overall early complication rates (5.5 % vs. 7.6 %, p = 0.08), late complication rates (1.6 % vs. 2.2 %, p = 0.42), and PDT-related mortality rates (0.7 % vs. 0.6 %, p = 0.73) did not exhibit significant differences between the two groups. In a propensity score-matched cohort, results remained consistent. CONCLUSIONS Physical examination can effectively identify major neck blood vessels without increasing the risk of bleeding during and after PDT.

Alzubaidi S, Wallace A, Naidu S, Knuttinen MG, Kriegshauser SJ, Oklu R, Al-Ogaili M, Patel I. Single-arm prospective study comparing ablation zone volume between time zero and 24 h after microwave ablation of liver tumors. Abdom Radiol (NY) 2024:10.1007/s00261-024-04185-z. [PMID: 38400983 DOI: 10.1007/s00261-024-04185-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Revised: 01/02/2024] [Accepted: 01/07/2024] [Indexed: 02/26/2024]
Abstract
PURPOSE Percutaneous thermal ablation is an effective treatment for primary and metastatic liver tumors and is a recommended local therapy for early-stage hepatocellular carcinoma (HCC). Reported evidence shows an increase in the ablation zone volume over the first 24-h post-liver ablation. This report compares ablation zone volumes immediately at the completion (T = 0) of 26 microwave ablations of liver tumors to 24-h post-procedure (T = 24) volumes. MATERIALS AND METHODS 20 patients, 13 (65%) males, underwent a total of 26 hepatic microwave ablations (MWA) under ultrasound guidance. Contrast-enhanced CT (CECT) or MRI was performed immediately and another CECT 24 h post operatively. Evaluation of the ablation zone and comparison of the two post-operative scans were done using BioTrace software. The expansion of ablation zones on post-op CECTs was matched point by point per direction. The distance between each 2 points was measured and grouped by distance. The incidence of each specific distance was then converted into a percentage, first for each case separately, then for all cases altogether. Data were tested by a matched paired one-sided t test. RESULTS The median lesion diameter was 1.5 cm (range 0.5-3.3) with 16 (62%) HCC cases and 9 hepatic metastases (4 neuroendocrine carcinoma, 4 colorectal carcinomas, 1 breast carcinoma, 1 pancreatic cancer). The data show a consistent volume expansion greater than 30% (p = 7.7e-5) 24-h post-ablation, where the median expansion is 57%. Distances between T = 0 and T = 24 equal to 3-7 mm occur in over 35% of the cases. CONCLUSION The ablation zone expansion at 24-h post-op was not uniform. The final ablation zone is difficult to predict at the time of the procedure. The awareness of the ablation zone expansion is important when treating near-critical structures, managing the heat sink effect, and preserving liver parenchyma.

Abstract
OBJECTIVES To Investigate the value of 3D printed guide-assisted percutaneous management of minimally displaced scaphoid waist fractures(Herbert's B2) with delayed diagnosis or presentation. METHODS From October 2018 to February 2022, 10 patients with established delayed diagnoses and presentation of minimally displaced scaphoid waist fractures were treated with 3D printed guides assisted with percutaneous internal fixation without bone grafting. This technique was based on the patient's preoperative CT and imported into the software. Based on Boolean subtraction, the most centralized screw placement position was identified and a customized guide was produced. Intraoperative percutaneous insertion of the guide wire was assisted by the custom guide. RESULTS All 10 patients were successful in one attempt. The fractures healed at a mean of 7.7 weeks postoperatively (range 6-10 weeks). At a mean follow-up of 7.7 months (6-13 months), patients had excellent recovery of wrist function with minimal pain reduction. There were no major postoperative complications and the patients all returned to their previous activities before the injury. CONCLUSIONS Percutaneous internal fixation based on 3D printed guides is a safe and effective technique for delayed diagnosis or presentation of patients with minimally displaced fractures of the scaphoid waist. This method allows for easy insertion of screws and avoids multiple attempts.

Abstract
OBJECTIVE Spinal cord stimulators (SCSs) can be implanted via a percutaneous or paddle approach, the latter technique requiring a laminotomy or laminectomy. Revision surgery may be necessary in instances of migrated, misplaced, or failed stimulators. When revision of a percutaneous system is necessary, it is common to replace the electrodes with a paddle SCS. This study aims to describe a case series of patients with failed paddle SCS electrodes who underwent revision with percutaneous SCS hardware. METHODS A series of 5 patients were retrospectively analyzed. Medical records were reviewed for demographic data, operative technique, postoperative follow-up, and complications. RESULTS Five patients were included in this series. The median age was 63 (range 51-84), and the median duration from initial implantation to revision surgery was 19 months (range 5-60). The median operative duration was 92 minutes (mean 99 ± 19.6 minutes). The median length of follow-up after surgery was 24 months (mean 21.8 ± 6.0 months). All patients had improved pain relief and therapeutic coverage with no complications. CONCLUSIONS Paddle-to-percutaneous SCS surgery is a feasible and durable revision option in appropriately selected patients.

Abstract
Interventional approaches to head and neck vascular anomalies have evolved with our understanding of disease pathologic condition and advances in medical and surgical treatment. Embolization's role in the disease management ranges from stand-alone treatment with curative intent to adjunctive or even palliative, depending on the lesion. This decision is best made through multidisciplinary collaboration among surgeons, interventionalists, and medical specialists. Finally, setting realistic expectations with the patient and family is a crucial step preceding any intervention. This article elaborates on the considerations influencing a given treatment plan and specific interventional strategy.

Abstract
The use of coronary physiology allows for rational decision making at the time of PCI, contributing to better patient outcomes. Yet, coronary physiology is only one aspect of optimal revascularization. State-of-the-art PCI must also consider other important aspects such as intracoronary imaging guidance and specific procedural expertise, as tested in the SYNTAX II study. In this review, we highlight the technical aspects pertaining to the use of physiology as used in that trial and offer a glimpse into the future with emerging physiologic metrics, including functional coronary angiography, which have already established themselves as useful indices to guide decision making.

Percutaneous versus traditional open approaches for the treatment of thoracolumbar fractures in patients without neurologic deficits: a meta-analysis of 35 cohort studies. Neurosurg Rev 2024; 47:62. [PMID: 38263482 DOI: 10.1007/s10143-023-02259-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Revised: 11/23/2023] [Accepted: 12/18/2023] [Indexed: 01/25/2024]
Abstract
At present, percutaneous surgery is widely used to treat thoracolumbar fractures. However, the actual safety, feasibility, and effectiveness of percutaneous surgery are not clear. Through systematic review and meta-analysis, we compared the efficacies of percutaneous pedicle screw fixation and open pedicle screw fixation in the treatment of thoracolumbar fractures without nerve root symptoms. We systematically searched the PubMed, Embase, and Cochrane libraries for articles published on or before June 2023. All results were evaluated by standard methods recommended for meta-analysis, continuous data were expressed by standard mean differences (SMDs), and binary variables were analyzed by odds ratios (ORs) and 95% confidence intervals (95% CIs). We also explored the main sources of heterogeneity and the stability of the results through sensitivity analysis, Begg's funnel plots, and Egger's test. Thirty-five cohort studies with a total of 3039 patients were included. The study found that patients who undergo percutaneous approaches have less intraoperative blood loss (IBL), shorter length of hospital stay (LOS), shorter operation time, and shorter incision. Moreover, percutaneous approaches had more advantages in terms of visual analog scale (VAS) scores, Oswestry Disability Index (ODI) scores, and infection rates. However, there was no significant difference in anterior vertebral body height (AVB), Cobb angle (CA), or screw errors between the two groups. In the long run, the clinical and surgical results of the percutaneous approach are better than those of the open approach, but the radiological results of both operations do not seem to show an advantage for any specific approach. Because of publication bias and heterogeneity, our findings must be interpreted with caution. However, this paper will provide some support for clinicians to choose suitable surgical methods for the treatment of thoracolumbar fractures.

Abstract
BACKGROUND This retrospective multicentric study aims to report on technical safety and effectiveness of pseudoaneurysms embolization with glue (N-butyl cyanoacrylate) adopting a percutaneous direct puncture approach. RESULTS Fifty-four patients data were collected from five centers. All patients at the time of treatment presented with unruptured PAs and were hemodynamically stable. True aneurysms and lesions treated with embolics other than glue were excluded. Pseudoaneurysms diagnosis was based on CT and anamnestic data; initial investigation with digital-subtracted arteriography was acquired in all cases; then, percutaneous embolizations were performed in the angio-suite (ultrasound, fluoroscopy, ConeBeam CT guidance) or in CT. Technical success was considered as complete pseudoaneurysm embolization at final imaging with sole percutaneous strategy, without need for additional endovascular embolization. Clinical success was intended as pseudoaneurysm resolution within one week follow-up with stabilization or restored clinical conditions. Pseudoaneurysms origins were traumatic (57.4%), inflammatory (24.1%) or spontaneous (18.5%); 39 patients (72.2%) were symptomatic, presenting with pain and/or pulsatile mass. Mean lesions diameter was 19.3 mm (range: 7-30); pseudoaneurysms were located in abdomen (48.1%), limbs (42.6%) and thorax (9.3%). Coagulation function was impaired in 16.6% and 48.1% was under antiplatelets/anticoagulation therapy. In 16.6% the percutaneous approach followed previous treatments failure. The image-guidance modality for percutaneous puncture was most often ultrasound combined with fluoroscopy (38%). Clinical success was obtained in all patients while technical success occurred in 94.4% because 3 patients required an additional endovascular embolization. Complications were registered in 14.8%, all of low grade without clinical sequelae neither prolonged recovery (7 non target embolizations, 1 post-embolization syndrome). CONCLUSIONS In this study, pseudoaneurysms embolization with glue via percutaneous direct puncture was safe and effective with a low rate of minor complications.

Abstract
With the increasing use of cardiac implantable electronic devices, the number of patients with cardiac implantable electronic device-related endocarditis is also rising. The treatment of this type of endocarditis is a challenging clinical task, in particular if device removal is required in patients who are pacemaker dependent. This video tutorial describes a treatment strategy for cardiac implantable electronic device-related endocarditis involving the tricuspid valve in pacemaker-dependent patients. The proposed treatment strategy consists of implanting an epicardial pacemaker via a minimally invasive subxiphoid approach, percutaneous aspiration of tricuspid valve vegetations and complete transvenous explantation of the infected cardiac implantable electronic device system using advanced lead extraction tools.

Abstract
BACKGROUND This study aimed to investigate the positional consistency between the guidewire and the screw in spinal internal fixation surgery. METHODS This study involved 64 patients who underwent robot-assisted thoracic or lumbar pedicle screw fixation surgery. Guidewires were inserted with the assistance of the Tirobot. Either cannulated screws or solid screws were inserted. Guidewire and screw accuracy was measured using CT images based on the Gertzbein and Robbins scale. The positional consistency between guidewire and screw was evaluated based on the fused CT images, which could graphically and quantitatively demonstrate the consistency. The consistency was evaluated based on a grading system that considered the maximum distance and angulation between the centerline of the guidewire and the screw in the region of the pedicle. RESULTS A total of 322 screws were placed including 206 cannulated ones and 116 solid ones. Based on the Gertzbein and Robbins scale, 97.5% of the guidewires were grade A, and 94.1% of the screws were grade A. Based on our guidewire-screw consistency scale, 85% in cannulated group, and 69.8% in solid group, were grade A. Both solid and cannulated screws may alter trajectory compared to the guidewires. The positional accuracy and guidewire-screw consistency in the solid screw group is significantly worse than that in the cannulated screw group. The cortical bone of the pedicle has a positive guide effect on either solid or cannulated screws. CONCLUSION The pedicle screws may alter trajectory despite the guidance of the guidewires. Solid screws show worse positional accuracy and guidewire-screw consistency compared with cannulated screws. Trial registration The study was retrospectively registered and approved by our center's institutional review board.

Abstract
INTRODUCTION Bone conduction devices (BCD) are effective for hearing rehabilitation in patients with conductive and mixed hearing loss or single-sided deafness. Transcutaneous bone conduction devices (tBCD) seem to lead to fewer soft tissue complications than percutaneous BCDs (pBCD) but have other drawbacks such as MRI incompatibility and higher costs. Previous cost analyses have shown a cost advantage of tBCDs. The purpose of this study is to compare long-term post-implantations costs between percutaneous and transcutaneous BCDs. MATERIALS AND METHODS Retrospective data from 77 patients implanted in a tertiary referral centre with a pBCD (n = 34), tBCD (n = 43; passive (tpasBCD; n = 34) and active (tactBCD; n = 9) and a reference group who underwent cochlear implantation (CI; n = 34), were included in a clinical cost analysis. Post-implantation costs were determined as the sum of consultation (medical and audiological) and additional (all post-operative care) costs. Median (cumulative) costs per device incurred for the different cohorts were compared at 1, 3 and 5 years after implantation. RESULTS After 5 years, the total post-implantation costs of the pBCD vs tpasBCD were not significantly different (€1550.7 [IQR 1174.6-2797.4] vs €2266.9 [IQR 1314.1-3535.3], p = 0.185), nor was there a significant difference between pBCD vs tactBCD (€1550.7 [1174.6-2797.4] vs €1428.8 [1277.3-1760.4], p = 0.550). Additional post-implantation costs were significantly highest in the tpasBCD cohort at all moments of follow-up. CONCLUSION Total costs related to post-operative rehabilitation and treatments are comparable between percutaneous and transcutaneous BCDs up to 5 years after implantation. Complications related to passive transcutaneous bone conduction devices appeared significantly more expensive after implantation due to more frequent explantations.

Abstract
PURPOSE OF REVIEW Spinal cord stimulation (SCS) has been used for decades to alleviate chronic pain. A growing body of literature suggests that the procedure is not without risks. Understanding the risks of SCS implantation can help treating physicians formulate individualized care plans that promote patient safety and minimize risks. RECENT FINDINGS The overall complication rate associated with SCS has been reported to be 31.9 to 43%. The most common complication in the literature appears to be electrode migration. Other complications ranging in rates of occurrence include hematoma formation, infection, spinal cord injury, and cerebrospinal fluid (CSF) leak. Case reports of syrinx formation, foreign body reaction, and fibrosis have also been described. Our review shows that there are strategies available to reduce and prevent complications. In addition, close monitoring and early intervention may prevent some of the adverse neurological outcomes. Nevertheless, additional research regarding patient and procedural factors is necessary to improve the safety profile of this intervention.

Abstract
OBJECTIVE The aim of this study was to analyze the outcomes and complications of minimally invasive plate osteosynthesis (MIPO) for displaced proximal humerus fractures and elucidate if the percutaneous technique reduces the rate of avascular necrosis (AVN) without jeopardizing fracture reduction. MATERIAL AND METHODS 118 patients with a displaced proximal humerus fracture were treated with a polyaxial locking-plate through a standardized percutaneous approach. 73 % were women and mean age was 63 years (18-89) with an average follow-up of 51 months (12-256). There were 32 two-part fractures (27 %), 57 three-part fractures (48 %) and 24 four-part fractures (25 %). Shoulder function at the last follow-up, including ROM and ability to perform daily living activities, was objectively evaluated with an adjusted Constant Score (CS). Subjective patient satisfaction was rated with an Visual Analogic Scale from 0 to 10 and the degree of residual pain with a Verbal Rating Scale (VRS). Radiographic analysis at the most recent follow-up evaluated the presence of AVN, degree of residual medial calcar displacement, and the cervicodiaphiseal angle. RESULTS Forty patients (34 %) had a complication, 25 of them (21 %) requiring further surgery. ROM at the last follow-up was 131° of elevation (40°-180°), 38° of external rotation (SD: 17.7) and internal rotation to L3. Average adjusted Constant Score was 68 (SD: 17.76). Twenty-one patients (18 %) complained of shoulder pain (14 moderate and 7 severe) and seven were not satisfied. Radiographically, 29 patients (25 %) had varus malunion and 17 patients (14 %) showed some degree of AVN. Patients with varus malunion (CS 64.3 versus 69.8, p = 0.16) and AVN (CS 56.9 versus 70.4, p = 0.005) had lower CS. The presence of a varus malunion was directly related to the degree of initial medial calcar displacement (p = 0.001) and deficient calcar reduction at surgery (p = 0.004). AVN was statistically more prevalent when the medial calcar was inadequately reduced (p = 0.01). CONCLUSIONS MIPO surgery for proximal humerus fractures through an anterolateral approach does not reduce the rate of mechanical complications or AVN compared with standard ORIF techniques. Moreover, percutaneous plating may preclude adequate medial calcar reduction, leading to humeral head malunion and a worse clinical outcome.

Abstract
Introduction Management of spondylolysis in adolescents is generally successful with conservative management. Uncommonly, surgical fixation is necessary for refractory cases. Direct repair with intralaminar screws is one commonly utilized technique. Recently, less invasive spinal procedures are becoming viable with the enabling of technologies, including robotics. Case description A 14-year-old baseball player and surfer presented with low back pain, diagnosed by MRI as bony edema and stress fractures of the posterior spinal elements. After 18 months, the pain was unresponsive to rest, physical therapy, and bracing. There was no radicular pain or neurologic symptoms. Computed tomography (CT) revealed bilateral, chronic nonhealing pars defects at L5. He underwent outpatient, robot-assisted percutaneous intralaminar fixation with hydroxyapatite-coated screws through a 2 cm skin incision. Outcome On postoperative day 1, the patient reported relief of his preoperative pain and he was ambulating without difficulty. At 2 weeks follow-up, the patient was completely pain free and surfing. At 2 months follow-up, low-dose CT demonstrated partial incorporation of the hydroxyapatite-coated screws, and the patient returned to sports. At 6 months follow-up, the patient had no pain and was swinging his baseball bat with full force. Low-dose CT revealed complete healing of the defects with full incorporation of the hydroxyapatite-coated screws. Conclusions A novel minimally invasive robotic percutaneous approach for direct spondylolysis repair using hydroxyapatite-coated screws is a potential surgical treatment option for non-healing pars defects in adolescent patients.

[PMID: 37832868 DOI: 10.1016/j.otsr.2023.103705] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/27/2021] [Revised: 05/13/2023] [Accepted: 05/17/2023] [Indexed: 10/15/2023]
Abstract
INTRODUCTION Percutaneous forefoot surgery has been associated with higher radiation exposure than the conventional approach. However, there is little data on forefoot surgery using a mini C-arm intensifier. We, therefore, conducted a prospective study to (1) evaluate the intraoperative radiation received by the surgeon during percutaneous forefoot surgery with a mini C-arm; (2) compare the radiation received by the surgeon with the guidelines for occupational exposure issued by the International Commission on Radiological Protection (ICRP) (20 millisieverts per year [mSv/year] for the whole body, 500mSv/year for the hands, and 20mSv/year for the lens of the eye); and (3) compare the radiation received during percutaneous forefoot surgery with that of the open approach, which has already been reported in the literature. HYPOTHESIS The radiation received by the surgeon during percutaneous forefoot surgery with a mini C-arm is lower than the ICRP guidelines, and the findings reported in the literature. MATERIALS AND METHODS This prospective single-center study was conducted from September 2020 to May 2021. A total of 639 feet (i.e., 435 patients) were included. Of these 639 feet, 336 (52%) were hallux valgus repairs, 49 (8%) were stand-alone procedures of the lateral rays, and 124 (19%) were a combination of both. The radiation dose data was retrieved from the mini C-arm daily: dose-area product (DAP) in centigray per square centimeter (cGy/cm2) and radiation exposure duration in seconds. The doses received by the surgeon were collected every month by 4 passive dosimeters (hand, eye lens, and chest [on and under the lead apron]) and 2 active dosimeters (on and under the lead apron). RESULTS The DAP emitted by the mini C-arm during an operating day was 0.10±0.01cGy/cm2 (range, 0.0-3.9), and the mean daily radiation duration was 34.7±19.3seconds (range, 0.7-226.8). There was a mean of 8±8 (range, 1-18) elective procedures per operating day. The daily reading on the active dosimeter worn on the lead apron was 0.002±0 microSv (range, 0-0.04), while the one worn under the apron was 0.001±0 microSv (range, 0-0.03). The equivalent doses over the 7-month study period for the hand, eye lens, and chest (over and under the apron) were 0.14mSv, 0mSv, 0.22mSv, and 0mSv, respectively. DISCUSSION/CONCLUSION The radiation exposure in percutaneous forefoot surgery with a mini C-arm intensifier observed in our study was lower than the ICRP recommendations and literature findings during open surgery. LEVEL OF EVIDENCE IV; prospective study without a control group.

Abstract
RATIONALE AND OBJECTIVES To evaluate the targeting accuracy of laser-guided punctures in combination with an aiming device for computed tomography (CT) interventions during in vitro experiments. MATERIALS AND METHODS: A total of 600 CT-guided punctures were performed using a laser target system, half of them with the additional help of an aiming device. Conically shaped targets in a plexiglass phantom were punctured. The planning CT data sets were acquired with 1.25, 2.5 and 5 mm slice thickness. Needle placement accuracy, as well as procedural time, was assessed. The Euclidean (ED) and normal distances (ND) were calculated at the target point. RESULTS Using the aiming device, the accomplished mean ND at the target for the 1.25, 2.5 and 5 mm slice thickness was 1.76 mm (SD ± 0.92), 2.09 mm (SD ± 1.06) and 1.93 mm (SD ± 1.38), respectively. Without aiming device, the corresponding results were 2.55 mm (SD ± 1.42), 2.7 mm (SD ± 1.43) and 2.31 mm (SD ± 1.64). At a slice thickness of 1.25 mm and 2.5 mm, punctures with the aiming device were significantly more accurate for both the ED and ND as compared to the punctures without aiming device (p < 0.001). The mean time required to complete the procedure, including image acquisition, trajectory planning, the placement of 10 needles, and the control-CT scan was 24.8 min without and 29.8 min with the aiming device. CONCLUSION The additional use of the aiming device in combination with the commercially available laser guidance system significantly increased the level of accuracy during this in vitro experiment compared to freehand passes.

Abstract
Most infectious endocarditis patients can be managed medically. However, non-responders to antibiotics and ongoing sequelae such as septic emboli, may require mechanical interventions. AngioVac (Angiodynamics, Latham, NY, USA) is a percutaneous aspiration device used for removal of thrombi, emboli, masses, and vegetations. Main drawbacks are the requirement for a perfusionist, two large-bore accesses, and meticulous de-airing. These drawbacks make the procedure more time-consuming and possibly increase the risk of complications. AlphaVac (Angiodynamics) omits the motor element, thereby overcoming several of the limitations. In the current report, we describe two cases of percutaneous aspiration of tricuspid valve vegetations using AlphaVac. Learning objective To consider manual percutaneous aspiration of infective valvular vegetations using the AlphaVac cannula in case of insufficient response to antibiotics or for prevention of emboli.

Abstract
INTRODUCTION Peritoneal drainage is an established management strategy for spontaneous intestinal perforation (SIP) in premature infants. We sought to evaluate the safety and efficacy of percutaneous pigtail catheter placement as an alternative to drain insertion via a lower quadrant incision. METHODS Patients less than 32 weeks gestational age who underwent peritoneal drain placement for SIP at two neonatal intensive care units between 2011 and 2022 were identified. Incisional drainage (ID) or percutaneous pigtail catheter drainage (PD) was used based upon the usual practices of the surgeons. ID (n = 19) was performed via a 5-mm right lower quadrant incision into which a one-fourth-inch Penrose or red rubber catheter was placed. PD (n = 18) was accomplished using a Seldinger technique by which a 6.0 or 8.5 F pigtail catheter was passed through the left lower quadrant. Demographics and physiological parameters at the time of drainage were recorded and short-term and long-term outcomes were evaluated. RESULTS Thirty seven infants were identified. There were no differences in demographics or physiological derangement between the groups. Patients who underwent ID had more frequent stool drainage, a greater transfusion requirement, and a longer time to full feedings (60.6 v 37.7 d, P = 0.04). Incisional hernias (n = 3, 16%) only developed after ID. The duration of drain placement, length of stay, and time to resolution of pneumoperitoneum were similar with ID and PD as was the incidence of premature drain dislodgement and subsequent laparotomy. CONCLUSIONS Percutaneous drain placement provided effective drainage in infants with SIP and was associated with more rapid feeding advancement and no incidence of incisional hernia.

Abstract
OBJECTIVE To compare the results of surgical treatment of midshaft clavicle fractures, treated with the technique of minimally invasive plate osteosynthesis (MIPO) with locking compression plate versus open reduction and internal fixation (ORIF) with locked plate. METHODS Quasi-randomized comparative study, evaluating displaced midshaft clavicle fractures treated with MIPO versus ORIF, with procedures performed by a single surgeon. We evaluated patients at 12 months using the University of California at Los Angeles (UCLA) scale and radiographically at 8, 12, 26 and 52 weeks, in addition to describing complications. RESULTS We evaluated 44 patients; 22 submitted to MIPO and 22 to ORIF. The median UCLA scores at 12 months were 35 in the ORIF group and 35 in the MIPO group (p = 0.712). All patients had fracture healing at 3 months (p > 0.999). The mean surgery time was 87.5 min in the ORIF group and 47.5 in the MIPO (p < 0.001) group. As complications, 1 suture dehiscence (4.5%), 2 protruding plates (9.1%) and 1 change in sensitivity around the surgical wound (4.5%) were observed in the MIPO group, while in the ORIF group, 15 changes in sensitivity (68.2%) and 3 hypertrophic scars (13.6%) were observed. The only complication that showed a difference between the groups was the change in sensitivity (p < 0.001). No cases of pseudarthrosis or failure of osteosynthesis were identified in either technique. CONCLUSION This study demonstrated that the two treatments, ORIF and MIPO, are equally effective in the treatment of displaced middle third clavicle fractures. However, MIPO is superior to ORIF in regard to reduced surgical time and preservation of supraclavicular nerve sensitivity.

Abstract
PURPOSE To highlight and compare experts' laser settings during endoscopic laser treatment of upper tract urothelial carcinoma (UTUC), to identify measures to reduce complications, and to propose guidance for endourologists. METHODS Following a focused literature search to identify relevant questions, a survey was sent to laser experts. We asked participants for typical settings during specific scenarios (ureteroscopy (URS), retrograde intrarenal surgery (RIRS), and percutaneous treatment). These settings were compared among the reported laser types to find common settings and limits. Additionally, we identified preventive measures commonly applied during surgery. RESULTS Twenty experts completed the survey, needing a mean time of 12.7 min. Overall, most common laser type was Holmium-Yttrium-Aluminum-Garnet (Ho:YAG) (70%, 14/20) followed by Thulium fiber laser (TFL) (45%, 9/20), pulsed Thulium-Yttrium-Aluminum-Garnet (Tm:YAG) (3/20, 15%), and continuous wave (cw)Tm:YAG (1/20, 5%). Pulse energy for the treatment of distal ureteral tumors was significantly different with median settings of 0.9 J, 1 J and 0.45 J for Ho:YAG, TFL and pulsed Tm:YAG, respectively (p = 0.048). During URS and RIRS, pulse shapes were significantly different, with Ho:YAG being used in long pulse and TFL in short pulse mode (all p < 0.05). We did not find further disparities. CONCLUSION Ho:YAG is used by most experts, while TFL is the most promising alternative. Laser settings largely do not vary significantly. However, further research with novel lasers is necessary to define the optimal approach. With the recent introduction of small caliber and more flexible scopes, minimal-invasive UTUC treatment is further undergoing an extension of applicability in appropriately selected patients.

Abstract
Percutaneous nephrolithotomy (Labate et al.) is the standard procedure for the treatment of large (≥2cm) kidney stones. The patient can be in prone or modified supine position. The puncture is performed under fluoroscopy and/or ultrasound guidance. The stone-free rate seems to be comparable between miniaturized and standard PCNL. Procedures performed with smaller diameter instruments tend to be associated with significant lower blood loss, but longer procedure times. The limitation of the number of percutaneous tracts results in better preservation of the kidney function and lowers the risk of complications. The use of tranexamic acid during PCNL may be interesting for reducing the bleeding risk, the transfusion rate, and possibly the intervention duration. METHODOLOGY: These recommendations were developed using two methods: the Clinical Practice Recommendation (CPR) method and the ADAPTE method, depending on whether the question was considered in the European Association of Urology (EAU) recommendations (https://uroweb.org/guidelines/urolithiasis [EAU 2022]) and their adaptability to the French context.

Abstract
PURPOSE OF REVIEW This review will describe the various applications, benefits, risks, and approaches of conventional irreversible electroporation (IRE), as well as highlight the new technological developments of this procedure along with their clinical applications. RECENT FINDINGS Minimally invasive image-guided percutaneous IRE ablation has emerged as a newer, non-thermal ablation technique for tumors in the solid organs, particularly within the liver, pancreas, kidney, and prostate. IRE allows for ablation near heat-sensitive structures, including major blood vessels and nerves, and is not susceptible to the heat sink effect. However, it is limited by certain requirements, such as the need for precise parallel placement of at least two probes with a maximum inter-probe distance of 2.5 cm to reduce the risk of arching phenomenon, the requirement for general anesthesia with muscle relaxant, and the need for cardiac synchronization. However, new technological advancements in the ablation system and image guidance tools have been introduced to improve the efficiency and efficacy of IRE. IRE is a safe and effective treatment option for solid tumor ablation within the liver, pancreas, kidney, and prostate. Compared with other ablation techniques, IRE has several advantages, such as the absence of heat sink effect and minimal injury to blood vessels and bile ducts while activating the immune system. Novel techniques such as H-FIRE, needle placement systems, and robotics have enhanced the accuracy and performance in placement of IRE probes. IRE can be especially beneficial when combined with chemotherapy, immunomodulation, and immunotherapy.

Abstract
Mini-percutaneous nephrolithotomy (MPCNL), which has a smaller tract size (14-20 Fr) than conventional percutaneous nephrolithotomy, has been shown to be safe and effective in pediatric patients with large and complex upper urinary tract stones. This study aimed to compare the efficacy and safety of MPCNL between the supine and prone positions in a pediatric population. The data of pediatric patients who underwent MPCNL at our center between January 2010 and March 2023 were retrospectively analyzed. According to the surgical position, the patients were divided into the prone (Group P) and supine (Group S) groups. In both groups, dilatation was performed using 14-18 Fr metallic dilators. The two groups were compared in terms of perioperative data, postoperative stone-free rates (SFRs), and complications. There were 36 (59%) patients in Group P and 25 (41%) patients in Group S. Stones were mostly located in the pelvis (49.2%) and second most frequently in the lower pole (27.9%). Fluoroscopy time was shorter in Group S but did not statistically significantly differ compared to Group P (p = 0.181). However, operation time was statistically significantly shorter in Group S (73.8 ± 35 vs. 99.8 ± 37.4 min, p = 0.008). Although there was no significant difference, relatively higher SFR were detected in Group S (88% vs. 83%, p = 0.725). Endoscopic combined intrarenal surgery (ECIRS) was performed on six (24%) patients in Group S, and the SFR was 100% among these patients. There was no significant difference between the two groups in terms of the presence of complications (16.7% vs. 16%, p = 0.945). Both supine and prone MPCNL appear to be safe and effective in the pediatric age group, with similar stone-free and complication rates. In the supine procedure, the operation time is shortened compared to the prone. In addition, simultaneous retrograde access has the potential to increase the overall success rate of surgery.

Abstract
OBJECTIVE Open reduction and internal fixation (ORIF) is the standard treatment of unstable Colles fracture among the elderly. Modified percutaneous K-wire fixation is becoming increasingly popular in recent years. However, there is controversy concerning its appropriate use. This study aimed to compare the early safety and efficacy of the two different treatments and provide an alternative method for the treatment of unstable Colles fracture among the older population. METHODS Electronic medical records of 60 consecutive unstable Colles fractures patients who underwent surgery from June 2019 to October 2021, by modified percutaneous K-wire fixation (30 patients) or ORIF (30 patients), were reviewed retrospectively. All cases were followed up for 3 months. The outcomes of patients were assessed with operation time, intraoperative blood loss, visual analog score (VAS) for wrist joint pain, palmar tilt (PT), radial inclination (RI), radial height (RH), Gartland-Werley score, total hospitalization costs, hospital stays, postoperative complications, and patient subjective satisfaction. General patient information was also collected. Independent Student's t-test or Mann-Whitney U test were used to compare continuous data. Pearson's chi-square test or Fisher's exact test were used to analyze the categorical data. RESULTS The operation time and intraoperative blood loss were significantly shorter in the K-wire group than in the ORIF group (p < 0.05). Compared with the ORIF group, the VAS of the K-wire group was significantly lower at 1 and 3 days postoperatively (p < 0.05), and no significant differences were observed in VAS between the two groups preoperatively and 7 days postoperatively (p > 0.05). There were no significant differences in the PT, RI, and RH between the two groups preoperatively and at 1, 4, and 8 weeks postoperatively (p > 0.05). Patients in the K-wire group had significantly shorter hospital stays and lower total hospital costs (p < 0.05). All patients were followed up for 3 months, and there was no significant difference in the Gartland-Werley score between the two groups (p > 0.05). Compared with the ORIF group, postoperative complications were lower, and patient subjective satisfaction was higher in the K-wire group, but there were no significant differences (p > 0.05). CONCLUSIONS Modified percutaneous K-wire fixation in the treatment of unstable Colles fracture among the elderly is a safe, effective, rapid, and minimally invasive surgical option for surgeons.

Abstract
Cancer is a leading cause of death, with the spine being the most common site for skeletal metastasis. The spine is also a site for primary malignancy, such as sarcoma and chordoma, as well as non-neoplastic pathologies. An accurate diagnosis of spinal neoplastic diseases is crucial in determining appropriate management. With the advent of personalised oncology, the need to establish a definitive histopathologic diagnosis to guide management is more important than ever. Percutaneous biopsy has proven to be safe and efficient in establishing a reliable histopathologic diagnosis. The spine, however, can be a challenging site to biopsy, due to the proximity of critical neurovascular, respiratory, and gastrointestinal structures. Successful spine biopsy depends on several factors: suspected diagnosis, size of the lesion, location within the spine, modality for best imaging guidance, operator experience, technical equipment considerations, and desired approach and associated limitations. The specimen must also be obtained with a biopsy route amenable to any future surgical intervention, with surgical input often sought, frequently in a multidisciplinary setting, to confirm procedure-specific goals and expectations. Knowledge of the requisite local anatomy, procedural and patient-specific indications, and contraindications and various approaches that may be used to access different segments of the spine, potential complications, and how to address these are keys to a successful percutaneous spinal biopsy, even in the most challenging of circumstances.
