A Comparison of Wound Related Complications Between Intramedullary and Lateral Plate Osteosynthesis After Fibula Osteotomy in the Lateral Approach Total Ankle Replacement.

Total ankle replacement (TAR) has evolved in the last decade from a procedure rife with complication and failure to a promising alternative to arthrodesis. The ability to maintain ankle joint range of motion is showing great promise in patient-reported outcomes, postsurgical pain, as well as long-term sequalae of joint fusion. Although TAR can be performed via either an anterior or lateral approach both with their own sets of benefits and potential complications, the consensus seems to be that one is no better than the other when performed by high-volume surgeons. Data were gathered over a 6-year period looking at an age- and gender-matched cohort of lateral approach TARs with either plate osteosynthesis or fibula nail fixation in the management of the fibula osteotomy and compared reoperation and infection rates with the working hypothesis that nail fixation would afford better outcomes. Secondary outcomes including rates of fibula union, tourniquet time as an adjunct to procedure length, and patient-reported outcome measures (PROMs) in the form of FAOS Quality scores were included. A total of 234 TARs were analyzed. Forty-five of these used intramedullary nail fixation (IM), and a control group of 45 plate osteosynthesis (PO) fixation cases was correlated. The Foot and Ankle International guidelines on reporting for complications arising from total ankle arthroplasty that resulted in reoperation were applied to the data set, and it was noted that 13 of 19 reoperations were noted in the PO group, which was statistically significant. Also of note, 12 of 16 patients treated with antibiotics, which included all those cases within the reoperation group, were noted to come from the PO group. This was also of statistical significance. Interestingly, the rate of fibula nonunion in the PO group was lower (8.88%) than that of the IM group (23.25%). Our results confirmed that the rates of reoperation and infection were statistically significantly improved with the use of nail fixation over plate fixation. This was tempered by a concerningly high nonunion rate. This article shows promising results for the use of a simple technique in improving long-term outcomes in ankle arthroplasty.

3D-Printing of Artificial Aortic Heart Valve Using UV-Cured Silicone: Design and Performance Analysis.

The advancement of medical 3D printing technology includes several enhancements, such as decreasing the length of surgical procedures and minimizing anesthesia exposure, improving preoperative planning, creating personalized replicas of tissues and bones specific to individual patients, bioprinting, and providing alternatives to human organ transplants. The range of materials accessible for 3D printing within the healthcare industry is significantly narrower when compared with conventional manufacturing techniques. Liquid silicone rubber (LSR) is characterized by its remarkable stability, outstanding biocompatibility, and significant flexibility, thus presenting substantial opportunities for manufacturers of medical devices who are engaged in 3D printing. The main objective of this study is to develop, refine, and assess a 3D printer that can employ UV-cured silicone for the fabrication of aortic heart valves. Additionally, the research aims to produce a 3D-printed silicone aortic heart valve and evaluate the feasibility of the final product. A two-level ANOVA experimental design was utilized to investigate the impacts of print speed, nozzle temperature, and layer height on the print quality of the aortic heart valve. The findings demonstrated that the 3D-printed heart valve's UV-cured silicone functioned efficiently, achieving the target flow rates of 5 L/min and 7 L/min. Two distinct leaflet thicknesses (LT) of the heart valve, namely 0.8 mm and 1.6 mm, were also analyzed to simulate calcium deposition on the leaflets.

The length of price&reimbursement negotiation procedures in Italy in the period 2021-2023 was independent from the price of medicines

Background: The duration of price&reimbursement (P&R) procedures is taken as a key performance indicator of Regulatory Agencies in Europe. In this study we have tested the hypothesis that the price of medicines may have negatively affected the duration of P&R negotiations in Italy in the period 2021-2023. Methods: Data were retrieved from the Intexo database, which included all medicines with EC approval within the period 2021-2023. Biosimilars, generics, gene therapies, Sars-Cov-2 vaccines and medicines with no negotiated price at the datalock of December 2023 were excluded from the analysis. The ex-factory price of the most expensive package was taken as the price of each reimbursed medicine, whereas the time between the publication of EC decision in the European GU and the publication of P&R AIFA decision in the Italian GU (gazette-to-gazette time) as well as the time between the submission of P&R dossier and the publication of AIFA decision in the Italian GU (AIFA negotiation time) were taken as the procedure duration. Results: Sixty-seven EC approved medicines completed the P&R procedure in Italy within the study period, and had a reimbursed price. The median and mean gazette-to-gazette times were 395 and 442.6 days, respectively, whereas the mean and median AIFA negotiation times were 389.5 and 434.7 days, respectively. The mean price was 10,942 euros. The analysis of correlation between the duration of procedure and the negotiated price showed that there is no correlation whatsoever between the length of procedures and the price of medicines. Conclusions: We can reasonably exclude that the price of medicines negatively affected the duration of P&R negotiation procedures.

Patent Ductus Arteriosus Morphology Changes in Preterm Neonates Undergoing Transcatheter Device Closure.

Evaluate patent ductus arteriosus (PDA) morphology changes in the preterm neonate undergoing transcatheter PDA closure (TCPC).We propose thetype F ductus is associated with lowercorrected gestationalage (CGA) and improved TCPCoutcomes. Retrospective review of premature neonates undergoing TCPC at a large volume institution from November 2020 to November 2023. Two independent cardiologists blindly reviewed angiograms to classify the PDA as one of the 6 published morphologies. Procedural characteristics and outcomes were compared for two cohorts of TCPC patients constituting the type F and the non-type F ductus; statistical significance set at p-value < 0.05. 104 TCPC neonates met inclusion criteria; these were categorized as type F (n = 44) and non-type F (n = 60) ductal morphology. Patients with type F ductal morphology was associated with African American race (p = 0.007), lower procedural/chronological age (p < 0.001), weight (p = 0.002), and CGA (p < 0.001). Procedural length was significantly shorter in the type F group (41 vs 57min; p < 0.01). Unsuccessful TCPC (n = 2) and device embolization (n = 2) events all occurred in patients with a non-type F ductal morphology. The CGA cut off < 34weeks represents a good predictor of having a type F ductus (sensitivity 0.93, specificity 0.67). Younger chronological andCGA are associated with type F ductal morphology. At this institution, a type F ductus was associated with a shorter TCPC procedure time and demonstrated a lower complication rate. This data may prompt consideration of earlier TCPC referral. However, determining ideal TCPC timing in premature neonates is multifactorial and requires a multidisciplinary review team.

Formulation of Quality Improvement Methodology for Risk Mitigation in Congenital Cardiac Catheterization.

The C3PO collaborative, with a history of successful quality improvement (QI) initiatives, leveraged registry participants to develop a multi-center QI initiative to reduce adverse events (AEs) in congenital cardiac catheterization. A 32-person, interdisciplinary working group analyzed audited data for all congenital cardiac catheterization cases from 2014-2017. The primary outcome was the occurrence of any high-severity (level 3/4/5) AE. Cases were organized from shortest to longest duration, and level 3/4/5 and 4/5 AE rates were summarized for each procedure duration decile. Observations from the root cause analysis were used to inform the creation of a key driver diagram and determine change strategies and implementation tools. To facilitate pre-procedure communication and risk assessment, an online risk calculator was developed using 2014-2019 data. Between 2014-2017, 14,717 cases were entered from 10 sites. Level 3/4/5 AEs occurred in 732 (5.0%) cases, while 4/5 AEs occurred in 224 (1.5%) cases. The key driver diagram defined three drivers: (1) Pre-Procedure Risk Assessment, (2) Possibly Preventable Events, and (3) Procedure Length Optimization. Actionable change strategies organized around five communication timepoints were developed in interdisciplinary discussions. Pre-case risk calculator outputs were available as a case summary print out and incorporated into a calendar for weekly schedule planning. Pre-intervention (2019) and preliminary intervention period data (2020-2021) are presented here. Through improved resource planning, the protocol equips catheterization teams to respond efficiently to AEs and possibly prevent escalation into dangerous events. This protocol provides reproducible interventions that can be adapted to local practice.

Laparoscopic Warshaw Procedure for Solid Pseudopapillary Neoplasms in Children

Background Solid pseudopapillary neoplasms (SPNs) arising in the body or tail of the pancreas can be amenable to laparoscopic distal pancreatectomy with or without concomitant splenectomy. The purpose of this study was to evaluate laparoscopic distal pancreatectomy for SPN using the Warshaw technique as a means to preserve spleens in children. Methods We reviewed our database of SPN patients 19 years and younger (January 2006-December 2023). Five had a laparoscopic Warshaw procedure. Using the volumetric analysis tool in Sectra, a pediatric radiologist calculated preoperative tumor, pancreas, and spleen volumes (including postoperative organ volumes) on computed tomography. Descriptive statistics were performed. Results All five spleens were salvaged, although small infarcts occurred centrally in four patients. Splenic volumes on first imaging after Warshaw averaged 93.9% of preoperative size. Splenic volumes were preserved over time, as the most recent scans averaged 110.6% of the preoperative spleen volume. Collateral flow through the short gastric arteries, inferred from dilation on scans, increased in all patients. Median tumor volume was 85.2 mL, and all SPN were resected with negative margins. No relapse occurred (median follow up: 407 days). Median estimated blood loss was 100 mL, median length of procedure was 4.9 hours, and median inpatient length of stay was 3 days. A multimodal pain regimen, including preoperative TAP blocks, non-opiate, and opiate medications, resulted in a median 81 Morphine Milligram Equivalents (MMEs) administered during the hospital stay. Conclusion Laparoscopic Warshaw for SPN in children appears highly effective at preserving splenic volume without compromising oncologic fidelity or consuming excess inpatient resources.

The influence of doctoral management and medical procedures on patient satisfaction: An analysis based on appointment and medical procedure data

The impact of medical procedures and physician management on patient satisfaction is investigated in this study. Physician experience, specialization, waiting time, and the length of medical procedures are the primary characteristics examined. Hospital appointment and procedure records were used to gather data, and waiting time and procedure length were used as stand-ins for patient satisfaction. Patient satisfaction is significantly impacted by waiting time, according to the results. There is a negative correlation between waiting time and satisfaction, particularly for specialists. Even though they have lengthier wait times, specialists and subspecialists nevertheless offer greater satisfaction than general practitioners. There were reduced wait times for doctors with five to ten years of experience. However, there was no discernible impact of the length of medical procedures on patient satisfaction. The main findings suggest that waiting time management is critical to improving patient satisfaction, while duration of medical procedures has no significant impact. Therefore, optimizing doctor scheduling and improving communication with patients should be considered.

Changing of Condylar Fracture Approach in Cipto Mangunkusumo Hospital

Management of condylar fracture draws controversy for over three decades. Previously, closed reduction with intermaxillary !xation (IMF) had been predominant for many surgeons, considering shorter length of procedure, ability to achieve preinjury occlusion with acceptable adjustment, and low cost of procedure. Introduction of osteosynthesis material rigid internal !xation (RIF) and adaptive miniplate !xation marked technology development in condylar fracture management and became popular in term of the applicability and outcome results. Over period time, several studies proposed vary classi!cation system and selection patient criteria for surgical treatment on the basis of age, location of fracture, degree of communition, direction of proximal fragment displacement, location of condylar head, concomitant medical illness or associated trauma, and patient’s preferences to achieve optimum goal. This review focuses on the shifting of condylar fracture management at Cipto Mangunkusumo Hospital from 2004-2012.

Effect of surgical timing on postoperative outcomes in patients with acute cholecystitis after delayed percutaneous transhepatic gallbladder drainage.

To date, the optimal timing for percutaneous transhepatic gallbladder drainage (PTGBD), particularly for patients who have missed the optimal window for emergency laparoscopic cholecystectomy (LC) (within 72 hours of symptom onset) has not been determined. To study the effects of LC timing on outcomes of grade II/III acute cholecystitis (AC) in patients with delayed PTGBD. Data of patients diagnosed with Tokyo Guidelines 2018 grade II or III AC who underwent delayed PTGBD followed by LC at a single hospital between 2018 and 2022 were retrospectively studied. According to the interval between gallbladder drainage and cholecystectomy, the patients were divided into early and delayed LC groups. Outcomes including surgery time, postoperative complications and hospital stay, and patient satisfaction were analyzed and compared between the two groups using t- and χ 2 tests. There were no significant differences between the two groups in intraoperative blood loss, postoperative abdominal drainage tube placement time, pain index, or total disease duration (all P > 0.05). Compared with those of the early LC group, the delayed group showed significant decreases in the length of procedure (surgery time), conversion rate to open surgery, degree of adhesions, surgical complications, postoperative hospital stay, and total treatment costs, and increased patient satisfaction despite a longer interval before PTGBD (all P < 0.05). For patients with grade II/III AC with delayed PTGBD, LC should be performed 2 weeks after PTGBD to decrease postoperative complications and hospital stays and improve patient satisfaction.

Loop duodenal switch confers more complications with little gain of weight loss compared to Roux-en-Y gastric bypass.

There are several surgical options each with their potential for complications, differences in length of procedure, and in meaningful outcomes. This study aims to explore those outcomes after Roux-en-Y Gastric Bypass (RYGB) and Loop Duodenal Switch (LDS). The purpose of this project is to offer a comparative analysis of RYGB and LDS at the NorthShore University Health System for up to 4years postoperatively. A retrospective review of a prospectively maintained database was queried for all patients who underwent RYGB and LDS from 2019 to 2023. Demographic, preoperative, post-operative data, and Quality of Life (QOL) data were included. χ2 and Kruskal-Wallis tests were used for comparison. Statistical significance was set at p < 0.05. Patient database included 238 patients who underwent RYGB, and 54 who underwent LDS. Initial BMI was significantly higher in LDS compared to RYGB (56.9 ± 8.0; 46.5 ± 7.3; p < 0.01). There were no statistically significant differences between reported comorbidities. There were no differences in intraoperative complications between the two groups, however postoperative complications were significantly higher in the LDS population (16.7%, 7.1%; p < 0.01). Percent total body weight loss (%TBWL) was significantly different at 2years post operatively with LDS having more %TBWL than RYGB (LDS: N = 10, %TBWL = 44.7 ± 14.1%; RYGB: N = 47) There were no statistically significant differences at any other postoperative time point. Subgroup analysis was completed in patients with initial BMI 50. There were no significant differences at any postoperative time point. QOL data showed no significant difference between both procedures at all postoperative timepoints. Patients who undergo LDS are more likely to experience postoperative complications compared to RYGB with no added benefit in weight loss or comorbidity resolution up to 3years post operatively.

Abdominoplasty With Umbilical Hernia Repair: A Long-term Comparative Analysis of Clinical Outcomes.

The risks and benefits of performing small fat-containing ventral or umbilical hernia repair (HR) during cosmetic abdominoplasty remains a reconstructive and aesthetic challenge for plastic surgeons. This study aimed to compare clinical outcomes in patients undergoing abdominoplasty with concurrent HR and abdominoplasty alone. Retrospective review of patients undergoing abdominoplasty with and without a concurrent HR from January 2015- June 2022 was performed. Patients were stratified by concurrent HR. All hernia patients underwent primary fascial repair, without the use of mesh. Demographics, surgical site occurrences (SSO) and cosmetic complications, including delayed healing and necrosis were assessed. Multivariate analysis was used to compare association of umbilical hernia repair with clinical outcomes. One hundred and six patients underwent abdominoplasty, 68 (64%) had concurrent HR. No significant difference in demographics was identified between groups including mean BMI (HR=27.2 kg/m2 and No HR= 26.3 kg/m2, P=0.73), and number of previous open hernia repairs (P=0.09). After a mean follow-up of 1.5 years, hernia recurrence rate was 1.4% (n=1), with a time to hernia recurrence of 12.2 months. After controlling for confounders, there was no difference in risk of SSO (OR 1.02 [0.31-3.36] P=0.978), cosmetic complications (OR 0.80 [0.14-4.57] P=0.805), procedure length (-21.5 minutes [-46.92-22.93] P=0.501), readmissions (2.8% vs. 0%, P=0.336), or reoperations (8.8% vs. 10%, P=0.766), compared to patients who underwent abdominoplasty alone. Abdominoplasty with concurrent HR can be performed safely and effectively, with no increase in adverse outcomes or cosmetic complications. The benefit of performing mesh-free HR with abdominoplasty can achieve an enhanced aesthetic outcome and reduce long-term abdominal wall morbidity.

Abstract 281: Factors Leading to ICU Stays After Endovascular Treatments for Unruptured Intracranial Aneurysms: A Review Study

Background For unruptured intracranial aneurysms (UIAs), conservative management is often possible. However, when direct treatment is warranted, endovascular treatments (EVTs) provide an effective minimally invasive approach. These procedures still necessitate careful patient monitoring, frequently in the Intensive Care Unit (ICU). The factors leading to ICU admission for these patients remains an area of debate. Objective This systematic review aims to highlight existing literature and identify gaps in understanding the factors contributing to ICU admission following EVTs for UIAs. Methods We utilized the Nested Knowledge Autolit semi‐automated software to gather studies published before April 2024. We followed the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines, and included studies that met predetermined population, intervention, control, and outcomes (PICO) criteria. Statistical analysis was performed using R software. Results We retrieved 181 studies and 9 met our inclusion criteria. There was significant variability across these studies on what factors they reported. Across included studies there were 8,098 patients, with 5,620 requiring ICU admission following EVTs for UIAs. Analysis revealed that anterior aneurysm location, aneurysm‐related symptoms, and procedure length were significant factors leading to ICU admission. The overall ICU admission rate was approximately 24.61 per 100 patients. Conclusion This review underscores the need for further research to understand what factors lead to ICU admission following EVTs for UIAs. Additional studies are needed that use a standardized approach to collect data on patient demographics, aneurysm characteristics, procedural details, and postoperative outcomes. Such studies will allow for concrete recommendations to be made on ICU needs and prognostic calculators to be developed in order to support clinical decisions and lower healthcare costs.

Arbitrability of Corporate Disputes in Foreign Doctrine and Foreign Legal Systems

According to the current doctrine of civil law, the subject of law independently exercises civil rights, including the right to judicial protection. The choice of the form of protection is provided to the person whose rights have been violated, and this can also be attributed to the preliminary agreement of the parties to the corporate dispute. It should be noted that due to the length and inefficiency of judicial procedures, more and more attention has recently been paid to issues of alternative dispute resolution. In this regard, the out-of-court form of resolving corporate disputes is of particular interest. Due to the heavy workload of national courts, the issue of out-of-court dispute resolution is becoming increasingly important. At the same time, arbitration is considered a traditional method of resolving disputes even in Roman law. One of the controversial and legally unresolved issues in the theory of arbitration is the possibility of arbitration of disputes. The problem lies not only in the legislative definition of the term “arbitrability”, but also in the lack of clear standards regarding the arbitrability/ non-arbitrability of disputes. The need to study arbitrability is also due to the formation of an ambiguous position in the theory of arbitrability of disputes, including issues of company relationships. Thus, it can be concluded that the principle of arbitrability does not allow for sufficient answers to the question of the arbitrability of disputes with corporate elements. Thus, the need for scientific understanding of the theoretical foundations and the formation of a strong institution of arbitration and a theoretically sound concept of arbitrability both in theory and in practice determined the relevance of the research topic. Keywords: arbitrability, arbitration, corporate dispute, arbitration agreement, non-arbitrability.

A comparison study of 90-day readmission and emergency department visitation after outpatient versus inpatient pediatric pollicization surgery

IntroductionTransition to outpatient surgery has grown with an emphasis on delivery of safe, high-quality medical care. The purpose of this study is to compare 90-day emergency department (ED) visits, readmissions, and complications between patients undergoing outpatient versus inpatient pollicization surgery. MethodsA single institution database was queried for primary thumb pollicization from 2010 to 2022 in patients under 18 years of age. Standard demographic data, comorbidities, surgical information, and discharge disposition were collected. Primary outcome measures were complications including ED visits, unplanned reoperations and hospital readmissions within 90-days of index procedure. ResultsTwenty-seven patients underwent pollicization surgery. Twenty patients were outpatient surgery while 7 had postoperative hospital admission, defined as an overnight hospital stay. The outpatient cohort had no major postoperative complications including no ED visits, reoperations or readmissions within 90 days of index procedure. One outpatient experienced swelling around bilateral thumb pin sites without infection or vascular compromise. One inpatient represented to the ED within 90 days of surgery for bilateral hand cellulitis.All patients with ASA I classification were performed outpatient. Three of 7 inpatients (43 %) had congenital heart disease versus 5 of the 20 (25 %) outpatients. There was a trend that inpatients were younger than the outpatient cohort (19 vs. 33 months). The average length of procedure in the inpatient cohort was significantly longer than the outpatient cohort (237 vs. 173 min). Pollicizations performed between 2017 and 2022 were more likely to be outpatient than those performed between 2010 and 2016. ConclusionOn properly selected patients, outpatient pollicization appears to be a safe option. Patients with longer operative times were more likely to require postoperative hospital admission. Over the study years evaluated at our institution, pollicization procedures were more likely to be performed outpatient, reflecting an evolution of our practice. Level of evidenceLevel III, retrospective cohort study.

Case Volume Is Not Associated With Outcomes After Adrenalectomy Performed by Urologic Surgeons.

Our goal was to compare outcomes of adrenalectomy performed by low-volume and high-volume academic urologists with extensive experience in renal surgery. A single-center retrospective review identified patients undergoing adrenalectomy by urologists from 2009 to 2023. Data were gathered on demographics, tumor characteristics, surgeon volume, surgical outcomes including length of procedure, estimated blood loss, length of stay, and complications identified by the Clavien-Dindo complication classification system. Bivariable and multivariable analyses adjusting for BMI, size of mass, age, and surgical approach compared outcomes between low- and high-volume adrenalectomy surgeons. A total of 304 adrenalectomies were performed by 7 urologic surgeons during the study period. One surgeon was high volume, with an average of 15 adrenalectomies per year during the study period. The remaining 6 surgeons ranged from < 1 to 4 adrenalectomies per year on average during the study period and were considered low volume. On multivariable analysis, the rate of any complication was found to be significantly different between the groups (5.3% vs 13.5%, P = .01). However, on analysis of Clavien 3 or higher complications, the rate was not found to be different (1% vs 4%, P = .22). Procedure time (130 vs 134 minutes, P = .33), estimated blood loss (30 vs 50 mL, P = .86), positive margin rate (11% vs 7%, P = .35), and length of stay (2 days vs 2 days, P = .22) were not different when the surgery was performed by a high-volume or low-volume urologist. Surgical volume may not affect outcomes of adrenalectomy when performed by urologists experienced in retroperitoneal surgery at a high-volume, specialized center.

Digital health in the EP lab: routine implementation of remote access and technical support for complex ablation procedures

Abstract Background Complex electrophysiological procedures are performed using three-dimensional (3D) electroanatomical mapping (EAM) systems, which are usually operated on site, by field technical engineers (FTE). Due to a lack of skilled personnel, the engineers usually must travel between different hospitals and the procedures have to be planed in advance. Remote access (RA) technologies were recently implemented in clinical practice, aiming to increase the flexibility in the EP lab and maximise healthcare resources use. Methods Electroanatomical mapping was performed remotely by means of an integrated audio-visual solution for RA. The operator and the FTE communicated exclusively using the RA system, while the latter worked only in home office. Consecutive procedures were prospectively enrolled and analysed in terms of indication, procedural characteristics, feasibility and saved travelled time by the FTA. Results Between September 2022 and July 2023, a total of 133 EP procedures were performed in a high volume, tertiary electrophysiological centre in Germany. The mean age was 67 (57.5, 75.5) years. Women represented 39.8% of the population. The median BMI was 26.2 (23.1, 30.3) Kg/m2. A total of 56 (42.1%) patients underwent an atrial fibrillation ablation procedure (37.5% paroxysmal), 22 (16.5%) an atrial tachycardia ablation, 13 (9.8%) cavotricuspid isthmus ablation, 15 (11.3%) supraventricular tachycardia ablation, 14 (10.5%) a premature ventricular contraction ablation, 12 (9%) ventricular tachycardia ablations and 1 patient an electrophysiological diagnostic study. The median time length of procedure was 130 (96.5, 168) minutes. The median number of radiofrequency applications was 63.5 (22.3, 109.5), while the median RF time was 14.2 (6.9, 25.1) minutes. The fluoroscopy time was 9.2 (6.5, 12.6) minutes, with a median radiation dose of 408.5 (233.0, 631.8) cGy x cm2. The median amount of contrast media was 40 (8.75, 50.0) ml and the median amount of heparin administered was 12000 (8000, 16000) UI. Protamine was used in 9 cases, with a median of 7000 (5000, 7000) UI. Except for one supraventricular procedure, where no arrhythmia induction was possible, all procedures were successful. One major complication was observed. In one case, the internet-based headphone connection was not stable. Therefore, the communication was established via a conventional smartphone. No change to on-site support was needed. The travel time reduction was available in 130 cases. In total, 290 travel hours could be saved. Conclusion The routine implementation of RA for complex EP procedures proved to be safe and efficient. This approach has the potential to increase the feasibility in case of emergency procedures, reduce travel times for FTE and streamline healthcare resources allocation.

Simultaneous versus staged approach in transcatheter aortic valve implantation for severe stenosis and endovascular aortic repair for thoracic and abdominal aortic aneurysm.

Thoracic/abdominal aortic aneurysms and aortic stenosis may be concomitant diseases requiring both transcatheter aortic valve implantation (TAVI) and endovascular aneurysm repair (T/EVAR) in high-risk patients for surgical approaches, but temporal management is not clearly defined yet. The aim of the study was to analyse outcomes of simultaneous versus staged TAVI and T/EVAR. Retrospective observational multicentre study was performed on patients requiring TAVI and T/EVAR from 2016 to 2022. Patients were divided into 2 groups: 'Simultaneous group' if T/EVAR + TAVI were performed in the same procedure and 'Staged group' if T/EVAR and TAVI were performed in 2 steps, but within 3 months. Primary outcomes were technical success, 30-day mortality/major adverse events and follow-up survival. Secondary outcomes were procedural metrics and length of stay. Forty-four cases were collected; 8 (18%) had T/EVAR and 36 (82%) had EVAR, respectively. Upon temporal determination, 25 (57%) and 19 (43%) were clustered in Simultaneous and Staged groups, respectively. In Staged group, median time between procedures was 72 (interquartile range-IQR: 57-87) days. Preoperative and intraoperative figures were similar. There was no difference in 30-day mortality (Simultaneous: 0/25 versus Staged: 1/19; P = 0.43). Pulmonary events (Simultaneous: 0/25 versus Staged: 5/19; P = 0.01) and need of postoperative cardiac pacemaker (Simultaneous: 2/25 versus Staged: 7/19; P = 0.02) were more frequent in Staged patients. The overall length of stay was lower in the Simultaneous group [Simultaneous: 7 (IQR: 6-8) versus Staged: 19 (IQR: 15-23) days; P = 0.001]. The median follow-up was 25 (IQR: 8-42) months and estimated 3-year survival was 73% with no difference between groups (Simultaneous: 82% versus Staged: 74%; P = 0.90). Both Simultaneous or Staged T/EVAR and TAVI procedures are effective with satisfactory outcomes. Despite the small numbers, simultaneous repair seems to reduce length of stay and pulmonary complications, maintaining similar follow-up survival.

Single-Port Robotic Ureteroenteric Stricture Repair: A Retrospective Cohort Review.

Introduction The objective of this study is to present a series of 16 cases utilizing single-port robot-assisted repair for ureteroenteric anastomosis stricture (UES). To our knowledge, this is the first case series recorded detailing successful single-port UES revision. Methods A retrospective review of all patients under a single surgeon undergoing single-port robotic revision of ureteroenteric stricture following radical cystectomy with urinary diversion at our institutions from September 2020 through July 2024 was performed. Patient demographics and perioperative outcomes were assessed. Results The study consisted of 3 bilateral ureteroenteric strictures and 13 unilateral strictures, more commonly on the left. Stricture length averaged 2.2 cm on the left and 2.1 cm on the right. Surgeries were performed by a single surgeon using the da Vinci SP surgical system (Intuitive Surgical, Sunnyvale, California, US). The type of stricture repair included excision and primary anastomosis (EPA) with Bricker or Wallace reconstruction or Heineke-Mikulicz (HM) repair, although one case involved the necessity of revision ileocalycostomy. Two of the 16 cases were converted from robotic to open due to extensive adhesions. The average procedure length was 265 minutes (148-440). Length of stay (LOS) ranged from 0-46 days, averaging 4.9 days. There were five postoperative complications encountered including two seromas, two incisional hernias, and an episode of urosepsis. Pre- and postoperative changes in creatinine level ranged from -0.26 to 0.3 mg/dL. No renal units were lost.No patients were readmitted following initial surgical discharge. All patientsreturned for follow-up; none required repeat intervention. Conclusion SP robotic repair of ureteroenteric anastomoses is safe and feasible. The risk of complications is low with a high chance of success and possibly a lower length of stay;more research is warranted.

Waterjet pulse lavage as a safe adjunct to video assisted retroperitoneal debridement in necrotising pancreatitis

BackgroundMinimally invasive surgical necrosectomy plays an important role in the management of infected pancreatic necrosis, with a goal of removing debris and debriding necrotic tissue. Pulse lavage is designed to simultaneously hydrostatically debride and remove the infected necrotic tissue with suction. It is also able to remove significant amounts of debris without traumatic manipulation of the necrotic tissue which may be adherent to surrounding tissue and can result in injury.Methods and resultsThe surgical technique of utilising a waterjet pulse lavage device during the minimally invasive necrosectomy is detailed. Sixteen patients being managed via a step-up approach underwent endoscopic necrosectomy via a radiologically placed drain tract. All sixteen patients were successfully managed endoscopically without conversion to open necrosectomy, and survived their admission. There were no complications associated with the use of the waterjet pulse lavage.ConclusionWaterjet pulse lavage is a useful adjunct in minimally invasive necrosectomy, which reduces the length of the necrosectomy procedure, and facilitates removal of necrotic tissue while minimising the risk of traumatising healthy tissue.

Large bore access for transcatheter aortic valve replacement, endovascular aortic repair, and thoracic endovascular aortic repair. A review of anatomic challenges and operative considerations.

Transcatheter aortic valve replacement (TAVR), endovascular aortic repair (EVAR), and thoracic endovascular aortic repair (TEVAR) are standard and prolific procedures in the modern cardiovascular world, and appropriate delivery of these endoprostheses requires adequate understanding of the requisite large bore access. Percutaneous large bore access is the preferred route but may be accompanied by complications like thrombosis, hemorrhage, or inability to deliver the device. Anatomic limitations such as vessel tortuosity, small size, and heavy calcification may require alternative approaches for successful large bore access. This study aimed to better define large bore access, as well as to elucidate optimal adjuncts and alternatives to enable successful delivery of large bore endoprostheses. A systematic review for "large bore access" in the cardiovascular literature was conducted on PubMed and the Cochrane Library Central according to PRISMA guidelines. Identified articles were filtered and sub-selected for TAVR, EVAR, and TEVAR; studies related to other large bore interventions were excluded. A representative selection of 39 full-text studies included both cardiac and vascular studies and was critically interpreted to identify a consensus definition for large bore access, challenging anatomy, and adjuncts or alternative approaches to the standard transfemoral approach. Transfemoral access remains the first-line approach but in the setting of unfavorable anatomy, adjunct maneuvers (e.g. intravascular lithotripsy, endoconduits) or alternative approaches (supra-aortic, transcaval) help decrease morbidity, mortality, length of procedure, and overall health care cost in large bore access.
