Methods: The UBE approach targeted the ventral part of the superior articular process in the transforaminal UBE setup, specifically for upper lumbar disc herniation, with an approach angle of approximately 30º on the axial plane. Intraoperative navigation was employed to improve puncture accuracy for this relatively unfamiliar surgical technique. Navigation-assisted transforaminal UBE lumbar discectomy was performed on four patients presenting with back or leg discomfort due to disc herniation at the L1–L2 or L2–L3 levels. Results: All patients experienced symptom relief and were discharged on postoperative day 2. Conclusions Transforaminal UBE lumbar discectomy is a viable therapeutic option for upper lumbar paracentral disc herniation, which is typically associated with poor prognosis. Integrating navigation integration into this novel approach enhances precision and safety.

Methods: Twelve consecutive patients underwent single-level BELIF for lumbar degenerative disease. The technique involves two small portals, one each for endoscopy and instruments. A large PEEK cage was inserted through a posterolateral approach. Clinical outcomes, including a Visual Analog Scale for back and leg pain, the Oswestry Disability Index, and the European Quality of Life-5 Dimensions, were assessed preoperatively and at 3, 6, and 12 months postoperatively. Fusion status was evaluated using computed tomography (CT) at 12 months. Results: The mean patient age was 69.1±7.2 years, with operations predominantly at the L4–5 level (83%). The mean operation time was 149.7±37.4 minutes, and the average surgical drainage was 201.4±59.7 mL. All clinical outcome measures showed significant improvement at 12 months (p<0.05). Fusion was achieved in 83.3% of patients. Cage subsidence (>1 mm) occurred in one patient (8.3%). Complications included one case each of incidental durotomy, wrong-site surgery, and wound dehiscence and three cases of asymptomatic hematoma. Conclusions BELIF using a large PEEK cage demonstrated promising clinical outcomes and fusion rates. The technique offers enhanced visualization and enables direct neural decompression while minimizing tissue trauma. The use of a large PEEK cage may contribute to improved stability and reduced subsidence risk.

Biportal endoscopic spinal surgery (BESS) with interbody fusion is a relatively novel minimally invasive technique that was developed to reduce soft tissue trauma and intraoperative blood loss and shorten recovery time while achieving comparable clinical outcomes for lumbar degenerative diseases. Despite the growing interest in BESS, a comprehensive analysis of its effectiveness, complication rates, and long-term outcomes remains lacking. This systematic review evaluated the clinical outcomes, surgical efficacy, and complication rates of BESS with interbody fusion for lumbar degenerative diseases. Recent literature on endoscopic lumbar interbody fusion was included to expand the scope and gain new perspectives, thereby, providing a comparative analysis that highlighted the advantages, limitations, and emerging trends in minimally invasive spine surgery. This review synthesized current evidence to guide future research and clinical applications. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and using a combination of MeSH (Medical Subject Headings) terms and relevant keywords, PubMed/Medline and Scopus databases were systematically searched for studies published between January 2000 and September 2024. The studies were assessed using the ROBINS-I (Risk of Bias in Nonrandomized Studies of Interventions) tool to determine the risk of bias. From the 12 studies that provided clinical evidence, the data extracted were patient demographics; operative time; blood loss; clinical outcomes, such as Visual Analog Scale (VAS) and Oswestry Disability Index (ODI) scores and fusion rates; and complications. The mean operative time ranged from 98 to 206 minutes, with fusion rates between 70% and 95%. Most studies reported significant improvements in VAS scores for back and leg pain and ODI scores. Complications, including dural tears (2.9%–6.4%) and hematomas (1.4%–4.3%), were infrequent but notable. BESS with interbody fusion demonstrated excellent clinical outcomes, high fusion rates, and few complications. Although these results are promising, more randomized controlled trials and long-term studies are required to confirm the broader applicability, particularly in more complex or multilevel spinal pathologies.

Incidentally detected gallbladder polyps (GBPs) and gallbladder wall thickening (GBWT) are frequently encountered in clinical practice. However, characterizing GBPs and GBWT in asymptomatic patients can be challenging and may result in overtreatment, including unnecessary follow-ups or surgeries. The Korean Society of Abdominal Radiology (KSAR) Clinical Practice Guideline Committee has developed expert recommendations that focus on standardized imaging interpretation and follow-up strategies for both GBPs and GBWT, with support from the Korean Society of Radiology and KSAR. These guidelines, which address 24 key questions, aim to standardize the approach for the interpretation of imaging findings, reporting, imaging-based workups, and surveillance of incidentally detected GBPs and GBWT. This recommendation promotes evidence-based practice, facilitates communication between radiologists and referring physicians, and reduces unnecessary interventions.

Radiofrequency ablation (RFA) is a minimally invasive treatment modality used as an alternative to surgery in patients with benign thyroid nodules, recurrent thyroid cancers (RTCs), and primary thyroid microcarcinomas. The Korean Society of Thyroid Radiology (KSThR) initially developed recommendations for the optimal use of RFA for thyroid tumors in 2009 and revised them in 2012 and 2017. As new meaningful evidence has accumulated since 2017 and in response to a growing global interest in the use of RFA for treating malignant thyroid lesions, the task force committee members of the KSThR decided to update the guidelines on the use of RFA for the management of RTCs based on a comprehensive analysis of current literature and expert consensus.

Objective: Full endoscopic cervical surgery (FECS) is an evolving minimally invasive approach for treating cervical spine disorders. This systematic review synthesizes current evidence on the clinical outcomes and patient perspectives associated with FECS, specifically evaluating its safety, efficacy, and overall patient satisfaction. Methods: A systematic search of the PubMed/MEDLINE, Cochrane Library, Embase, and Web of Science databases was conducted following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Studies published between January 2000 and September 2024 that reported on clinical outcomes or patient perspectives related to FECS were included. Risk of bias was assessed using the ROBINS-I (Risk Of Bias In Non-randomized Studies - of Interventions) tool and the Cochrane Risk of Bias tool. Inclusion criteria encompassed randomized controlled trials, prospective cohort studies, retrospective studies, and observational studies focused on adult populations undergoing FECS for cervical spine surgery. Results: The final synthesis included 30 studies. FECS was associated with significant reductions in both cervical and radicular pain, as well as meaningful functional improvements, measured by standardized clinical scales such as the Neck Disability Index and visual analogue scale. Patient satisfaction rates were consistently high, with most studies reporting satisfaction exceeding 85%. Complication rates were low, primarily involving transient neurological deficits that were typically resolved without the need for further intervention. Nonrandomized studies generally presented a moderate risk of bias due to confounding and selection, whereas randomized controlled trials exhibited a low risk of bias. Conclusion FECS is a safe and effective minimally invasive surgical option for cervical spine disorders associated with substantial pain relief, functional improvement and high levels of patient satisfaction.

RESULTS: Resveratrol significantly reduced cardiac hypertrophy and remodeling in aging hearts. In addition, resveratrol significantly ameliorated aging-induced mitochondrial dysfunction (e.g., decreased oxygen respiration and increased hydrogen peroxide emission) and mitochondria-dependent apoptotic signaling (the Bax/Bcl-2 ratio, mitochondrial permeability transition pore opening sensitivity, and cleaved caspase-3 protein levels).Resveratrol also significantly attenuated aging-induced apoptosis (determined via cleaved caspase-3 staining and TUNEL-positive myonuclei) in cardiac muscles. CONCLUSION This study demonstrates that resveratrol treatment has a beneficial effect on aging-induced cardiac remodeling by ameliorating mitochondrial dysfunction and inhibiting mitochondria-mediated apoptosis in the heart.
