Background and Objectives: Implantation of cardiac implantable electronic devices (CIEDs) is increasingly performed in elderly and comorbid patients, for whom minimizing perioperative complications—including pain and systemic drug use—is critical. Traditional local infiltration often provides insufficient analgesia. The ultrasound-guided PECS II block, an interfascial regional technique, offers promising analgesic benefits in thoracic wall procedures but remains underutilized in cardiac electrophysiology. Materials and Methods: We conducted a prospective, controlled, non-randomized clinical study including 106 patients undergoing de novo CIED implantation. Patients were assigned to receive either a PECS II block (n = 53) or standard lidocaine-based local anesthesia (n = 53). Pain intensity was assessed using the numeric rating scale (NRS) intraoperatively and at 1, 6, and 12 h postoperatively. Secondary outcomes included the need for rescue analgesia, procedural duration, length of hospitalization, and patient satisfaction. Results: Patients in the PECS II group reported significantly lower NRS scores at all time points (mean intraoperative score: 2.1 ± 1.2 vs. 5.7 ± 1.6, p < 0.001; at 1 h: 2.5 ± 1.5 vs. 6.1 ± 1.7, p < 0.001). Rescue analgesia (metamizole sodium) was required in only four PECS II patients (7.5%) vs. 100% in the control group within 1 h. Hospital stay and procedural time were also modestly reduced in the PECS II group. Patient satisfaction scores were significantly higher in the intervention group. Conclusions: The ultrasound-guided PECS II block significantly reduces perioperative pain and the need for additional analgesia during CIED implantation, offering an effective, safe, and opioid-sparing alternative to conventional local infiltration. Its integration into clinical protocols for device implantation may enhance procedural comfort and recovery. Full article

Background: Recurrent apical pelvic organ prolapse (POP) presents significant management challenges, with limited evidence on optimal surgical approaches. This study evaluated the safety and long-term effectiveness of minimally invasive sacrospinous ligament (SSL) fixation using the EnPlace^® device for treating recurrent apical POP. Methods: A cohort analysis was performed on 82 consecutive patients (mean age 65.9 ± 8.6 years) with stage III or IV recurrent symptomatic apical POP. All patients underwent transvaginal SSL fixation using the EnPlace^® device between January 2021 and July 2023. Primary outcomes included anatomical cure rates, patient satisfaction, and complications. Long-term follow-up was conducted via a structured telephone survey in December 2024. Results: The mean interval between primary and recurrent repair was 3.2 ± 2.6 years. Most patients (64.6%) underwent surgery under regional anesthesia with a mean operative time of 24.1 ± 7.1 min and minimal blood loss (23.8 ± 6.5 mL). No intraoperative complications occurred, and 98.8% of patients were discharged the same day. Two early postoperative complications occurred, neither requiring surgical intervention. At six-month follow-up, significant improvements were observed in POP-Q measurements for apical prolapse, cystocele, and rectocele. Long-term follow-up (mean 31.6 ± 8.3 months) revealed that only 11 patients (13.4%) reported mild POP symptoms. Patient satisfaction scores averaged 90.8 ± 17.1, with only 8.5% reporting low satisfaction. Only two patients (2.4%) required additional intervention for recurrent apical POP. Conclusions: Minimally invasive SSL fixation using the EnPlace^® device demonstrates favorable safety and efficacy for recurrent apical POP, offering a viable alternative to more invasive procedures with high patient satisfaction and low recurrence rates.

Background: Iatrogenic nerve injuries (NIs) are an under-recognized complication of urological surgery. Though less common than vascular or organ damage, they may cause lasting sensory and motor deficits, significantly affecting patients’ quality of life. With increasing complexity in pelvic procedures, a consolidated understanding of nerve injuries is essential. Purpose: This review aims to synthesize current knowledge regarding peripheral and autonomic NIs in urological surgery, highlighting mechanisms of injury, associated procedures, preventative strategies, and treatment options. Scope: Focused on common urological interventions such as radical prostatectomy, cystectomy, pelvic lymphadenectomy, and reconstructive techniques, the review explores injuries from positional compression, traction, and intraoperative transection to their surgical management. Key Findings: The review categorizes nerve injuries into crush and transection types and details intraoperative signs and repair techniques. Skeletonization of nerves, avoidance of energy devices near neural structures, and prompt end-to-end anastomosis using 7-0 polypropylene are central to management. Adoption of novel sutureless nerve coaptation devices have also been described with promising outcomes. Early repair offers a better prognosis. New intraoperative technologies like NeuroSAFE during robotic-assisted procedures may enhance nerve preservation. Conclusion: Iatrogenic NIs, although rare, are clinically significant and often preventable. Prompt intraoperative recognition and repair are critical. Further research is warranted to develop standardized preventative protocols and enhance intraoperative nerve monitoring. A multidisciplinary approach, extended across surgical specialties, could improve outcomes and guide timely treatment of nerve injuries. Full article

This review provides an in-depth analysis of argatroban as an alternative anticoagulant in cardiac surgery, with a focus on its use in patients with heparin-induced thrombocytopenia (HIT). We examine argatroban’s pharmacokinetics and dosing regimens and the challenges associated with cosnventional monitoring methods—such as activated clotting time (ACT) and activated partial thromboplastin time (aPTT)—to evaluate its safety and effectiveness in high-risk surgical settings. Drawing on data from multiple case reports and series, our review highlights both the potential benefits and limitations of argatroban, including complications such as clot formation in extracorporeal circulation systems and prolonged postoperative coagulopathy. In addition to the literature review, we present a detailed clinical case of urgent HeartMate 3 left ventricular assist device implantation in a patient with advanced heart failure and active HIT. In this case, despite targeting an ACT above 400 s, intraoperative complications such as clot formation in the heart–lung machine and difficulty achieving hemostasis highlight the need for improved monitoring and dosing protocols. Our findings call for refined anticoagulation strategies and advanced monitoring techniques to optimize argatroban use in cardiac surgery, offering valuable insights for clinicians managing complex scenarios where conventional heparin therapy is contraindicated.

Background and Clinical Significance: Non-prosthetic peri-implant fractures (NPPIFs) are rare injuries occurring around internal fixation devices, and are distinct from periprosthetic fractures. While most studies focus on the femur, humeral NPPIFs remain poorly documented. This case illustrates a complex humeral NPPIF and highlights key surgical considerations. Case Presentation: A 62-year-old woman presented with a spiral humeral shaft fracture (AO 12B2) after a fall. Following closed reduction and antegrade intramedullary nailing, an intraoperative peri-implant fracture occurred at the distal interlocking screw. CT imaging revealed a complex fracture extending from the lateral condyle to the proximal humerus. Treatment included implant removal and open reduction with dual plate fixation—lateral distal and helically contoured proximal plates—plus cerclage bands and antibiotic-loaded beads. Recovery was uneventful, with a full range of motion achieved at six months. At one year, the DASH score and MEPS were 86 and 75, respectively. Conclusions: Humeral NPPIFs are challenging and require individualized, biomechanically sound strategies. This case reinforces the importance of intraoperative assessment and careful implant selection in humeral fracture management. Full article

Understanding the tensile properties of extraocular muscles (EOMs) is crucial for successful strabismus surgery and accurate predictions of surgical outcomes. Assessments of EOM tensile strength are traditionally highly dependent on the expertise of the ophthalmic surgeon, since they involve manually pulling the EOM in opposite directions. This approach only provides subjective measurements that are not quantifiable. Previous quantitative approaches have utilized various devices such as implanted force transducers or dial tension gauges connected to muscle tendons with nylon sutures, but these methods are complex and so are rarely used outside of research settings. Consequently, the goal of this study was to create a quantitative and clinically applicable device for assessing EOM tensile strength. This developed device uses a strabismus hook connected to a strain gauge load cell that measures the tensile force and includes a tilting sensor to ensure that the hook is pulled at a consistent angle when a force is applied. The performance of the device was tested on 22 EOMs in 11 patients with intermittent exotropia during surgery for resecting the medial rectus (MR) and recessing the lateral rectus (LR) under general anesthesia. The measured tensile strengths of the MR and LR were 284.9 ± 58.3 and 278.3 ± 64.6 g (mean ± SD), respectively. In conclusion, the novel device developed in this study for quantitative measurements of EOM tensile strength in clinical settings will facilitate understanding of the pathophysiology of strabismus, as well as of the mechanical properties of the EOMs, and enhance the precision of surgical interventions.

Background: Reamer–irrigator–aspirators (RIAs) are newer orthopedic devices intended to harvest bone while minimizing complications associated with traditional harvesting techniques. Its high success rate has resulted in relatively few studies on its intraoperative and postoperative complications, especially in pediatric populations. This study provides a scoping review of complications associated with the RIA and presents an institutional case series of RIA complications. Materials and Methods: The scoping review was conducted via modified Joanna Briggs Institute (JBI) guidelines. Cases at a single institution were selected on an individual basis as they occurred during or after RIA-associated surgeries. Results: Our case series consists of three males and one female, ranging from 8 to 14 years old, with varying comorbid orthopedic conditions. All complications occurred intraoperatively, with three instances of retained hardware and one instance of cortical disruption. Each complication was classified as stage I according to the modified Clavien–Dindo–Sink classification system. There were no long-term sequelae despite limited management. A scoping review of the literature revealed extremely limited data on pediatric complications, but several mechanical and clinical complications have been described. Conclusions: Complications associated with RIA use in children appear to be inconsequential, but data are very sparse, and further studies are required. Full article

Background: Hallux rigidus is a painful and degenerative pathology of the first metatarsophalangeal (MTP1) joint. In severe cases it is usually appropriate to consider arthrodesis or arthroplasty of the joint. Arthrodesis represents the gold standard, but arthroplasty allows patients to recover mobility. Although arthroplasty has slightly inferior functional results to arthrodesis, it has shown very good results in terms of joint mobility, patient satisfaction and pain reduction. The goal of the present study was to evaluate short-term outcomes of patients that received a third-generation double-stemmed MTP1 implant manufactured from high-performance silicon. Methods: In this retrospective study the authors analyzed data of 37 patients who underwent MPT1 joint arthroplasty with Silktoe^TM double-stemmed implant using the R 4.2.2 software (R Foundation for Statistical Computing, Vienna, Austria). The indications were hallux rigidus of grade III and grade IV (81.1%), hallux rigidus plus valgus (10.8%), painful or unstable joint following previous surgery (5.4%) and hallux rigidus due to gout (2.7%). Data were collected during routine visits at 1 and 6 months and 1 and 2 years. Results: There were no intraoperative and postoperative complications. There were no revisions or reoperations at a follow-up of two years. The American Orthopaedic Foot and Ankle Society-Hallux Metatarsophalangeal-Interphalangeal Scale (AOFAS-HMI) score was 94.6 ± 7.6 (median, 100; range, 70–100) and the Visual Analogue Scale (VAS) score was 0.4 ± 0.80 (median, 0; range, 0–3.5) at the final follow-up. Conclusions: The data from this study presented excellent short-term results for patients who received an arthroplasty of the MTP1 joint using a third-generation double-stemmed spacer made of high-performance silicone. For all patients who received the Silktoe^TM implant, AOFAS-HMI scores of 94.6 and VAS scores of 0.4 were obtained at a two-year follow-up. These values were in line with results reported in the literature for similar devices. Full article

Mammary tumours are the most common neoplasia in adult female dogs. Mastectomy leads to moderate to severe pain. Effective pain management is crucial in veterinary medicine. This review outlines analgesic techniques for managing perioperative pain in dogs undergoing mastectomy. A literature search on dog mastectomy analgesia was conducted from January 2001 to January 2025. Pre-emptive meloxicam reduces postoperative cardiovascular changes without affecting renal function. When combined with gabapentin, it lowers the need for rescue analgesic opioids, similar to robenacoxib. With regard to tramadol, it offers contrasting analgesia in the studies considered when used alone, while its effect appears enhanced when used in combination with meloxicam/dipyrone. However, methadone provides superior pain control, especially when given preoperatively or intraoperatively. The combination of ketamine, lidocaine, and maropitant enhances pain management, while fentanyl, alone or with lidocaine and ketamine, is effective for intraoperative pain control. Local infiltration with lidocaine/bupivacaine provides effective pain control, and devices like Comfont-in^® or WSC facilitate this process. Tumescent anaesthesia using lidocaine/ropivacaine allows for extensive infiltration of the mammary gland. Epidural analgesia, paravertebral blocks, and TAP blocks are beneficial in multimodal protocols. Transdermal patches containing fentanyl/buprenorphine offer prolonged analgesia, while electroacupuncture can help reduce the need for rescue analgesics. Multimodal analgesic protocols are crucial for effective pain management in dog mastectomy surgeries, minimising the need for rescue opioids. Full article

Background: Thromboelastography-6s (TEG^®6s), a novel device developed to assess coagulation status, presents advantages such as less frequent calibration, ease of use, and greater stability against movements compared to the previous system (TEG5000). This is the first study in the literature to compare coagulation profiles in the early postoperative period of liver resection (LR) using conventional coagulation tests (CCTs) and TEG^®6s. Methods: Forty-six adult patients admitted to the ICU post-surgery after elective LR for malignancy were included. CCTs were used to classify patients into hypocoagulable (HCG) (platelet count < 80 × 10⁹/L, international normalized ratio ≥ 1.4, or activated partial thromboplastin time > 38 s) and normocoagulable (all other cases) groups. Mann–Whitney tests, Spearman’s correlation, and linear regression were used. Results: On ICU admission, nineteen (41.3%) patients had a hypocoagulable profile based on CCTs, but only two (10.5%) of them were rated as hypocoagulable by TEG (p = 0.165). Intraoperatively, HCG patients experienced higher estimated blood loss (EBL) (p = 0.002); they required more fluids (p = 0.019), and more of them received red blood cell transfusions (p = 0.025). They also had higher postoperative arterial lactate levels (p = 0.036). Postoperative 12 h EBL was similar in the two groups (around 150 mL). The ICU stay was longer for HCG group (p = 0.010). Weak associations were observed between TEG/CCTs measures of coagulation initiation [e.g., between R time citrated rapid TEG, and international normalized ratio (r² = 0.448; p < 0.001)], clot formation [i.e., between conventional fibrinogen value using Clauss method and α-angle citrated rapid TEG (r² = 0.542; p < 0.001)], and clot strength [e.g., between conventional fibrinogen and citrated kaolin maximum amplitude (r² = 0.484; p < 0.001)]. Conclusions: CCTs revealed hypocoagulability that was not confirmed by TEG^®6s. However, the thromboelastography coagulation profile was more consistent with the detected non-relevant postoperative bleeding. Full article

Background: Artificial intelligence (AI) is rapidly transforming thoracic surgery by enhancing diagnostic accuracy, surgical precision, intraoperative guidance, and postoperative management. AI-driven technologies, including machine learning (ML), deep learning, computer vision, and robotic-assisted surgery, have the potential to optimize clinical workflows and improve patient outcomes. However, challenges such as data integration, ethical concerns, and regulatory barriers must be addressed to ensure AI’s safe and effective implementation. This review aims to analyze the current applications, benefits, limitations, and future directions of AI in thoracic surgery. Methods: This review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A comprehensive literature search was performed using PubMed, Scopus, Web of Science, and Cochrane Library for studies published up to January 2025. Relevant articles were selected based on predefined inclusion and exclusion criteria, focusing on AI applications in thoracic surgery, including diagnostics, robotic-assisted surgery, intraoperative guidance, and postoperative care. A risk of bias assessment was conducted using the Cochrane Risk of Bias Tool and ROBINS-I for non-randomized studies. Results: Out of 279 identified studies, 36 met the inclusion criteria for qualitative synthesis, highlighting AI’s growing role in diagnostic accuracy, surgical precision, intraoperative guidance, and postoperative care in thoracic surgery. AI-driven imaging analysis and radiomics have improved pulmonary nodule detection, lung cancer classification, and lymph node metastasis prediction, while robotic-assisted thoracic surgery (RATS) has enhanced surgical accuracy, reduced operative times, and improved recovery rates. Intraoperatively, AI-powered image-guided navigation, augmented reality (AR), and real-time decision-support systems have optimized surgical planning and safety. Postoperatively, AI-driven predictive models and wearable monitoring devices have enabled early complication detection and improved patient follow-up. However, challenges remain, including algorithmic biases, a lack of multicenter validation, high implementation costs, and ethical concerns regarding data security and clinical accountability. Despite these limitations, AI has shown significant potential to enhance surgical outcomes, requiring further research and standardized validation for widespread adoption. Conclusions: AI is poised to revolutionize thoracic surgery by enhancing decision-making, improving patient outcomes, and optimizing surgical workflows. However, widespread adoption requires addressing key limitations through multicenter validation studies, standardized AI frameworks, and ethical AI governance. Future research should focus on digital twin technology, federated learning, and explainable AI (XAI) to improve AI interpretability, reliability, and accessibility. With continued advancements and responsible integration, AI will play a pivotal role in shaping the next generation of precision thoracic surgery. Full article

Background: Intrauterine adhesions (IUAs) or Asherman syndrome (AS) represent pathological conditions that affect the endometrium and significantly influence female fertility through a variety of mechanisms. This study aims to identify risk factors, explore pathophysiological mechanisms, diagnostic approaches, and assess how medical background influence the development of these conditions. It also seeks to associate the severity of conditions with clinical outcomes, such as fertility, miscarriages, and menstrual cycle disorders, using American Fertility Society (AFS) scoring system. Materials and methods: This retrospective cohort study included 134 patients aged 18 to 45, who followed hysteroscopy between 2016 and 2024 at two hospitals in Iasi, focusing on those diagnosed with IUAs (102 patients) and AS (32 patients), based on hysteroscopic approach. The exclusions were based of factors like acute uterine bleeding, intrauterine device, obesity and other severe conditions. Results and discussions: Women over 35 years are more likely to develop these conditions due to prior gynaecological procedures which are often associated with fertility issues. Hysteroscopy is established as the gold standard for both diagnosis and treatment, intraoperative diagnosis representing 45.6 % of cases. Amenorrhea is a primary indicator in AS patients (OR = 26.19) and dysmenorrhea as a potential marker for IUAs (OR = 2.67). Patients with IUAs and primary infertility (82.9%) typically have an AFS score 1, corresponding to improved conception rates. Those with AS and primary infertility often present an AFS score 2 (54.5%); patients with AS and secondary infertility were linked to AFS score 3 (58.8%; p = 0.137). Although the incidence of miscarriages is comparable between the two groups, the timing differs: IUAs are predominantly associated with first trimester losses (64.9%), whereas AS is more commonly linked to second trimester miscarriages (45.5%; p = 0.001). Conclusions: The study highlights the necessity of a personalized approach in diagnosing and treating IUAs and AS, considering factors such as age, fertility index, and disease severity. The integration of hysteroscopic techniques with individualized treatment plans based on the patient’s unique medical profile is crucial for adequate management of IUAs and AS. Full article
