Background: Rosacea is a chronic inflammatory skin disorder characterized by erythema, papules, ocular symptoms, and heightened sensitivity. Patients with neurogenic symptoms such as burning or stinging remain particularly difficult to manage. Current guidelines often underrepresent energy-based devices (EBDs), pigmentary sequelae, psychosocial burden, and ocular comorbidities. Objective: To examine Korean dermatologists’ expert perspectives on rosacea management, focusing on skin sensitivity, neurogenic symptoms, pigmentary changes, psychosocial impact, ocular involvement, and EBD use. Methods: A web-based, 29-item survey was administered to 25 board-certified Korean dermatologists (May–June 2025). Quantitative and qualitative responses were analyzed. Results: Erythematotelangiectatic and papulopustular phenotypes with sensitivity skin predominated. EBDs (pulsed dye laser, intense pulsed light) were frequently used but limited by cost and sensitivity issues. Neurogenic symptoms were recognized but rarely treated with neuromodulators. Post-inflammatory hyperpigmentation was infrequent, yet monitoring was inconsistent.Psychosocial and ocular aspects were acknowledged but seldomly systematically addressed.Respondents expressed interest in emerging adjunctive treatments such as cold plasma, skin boosters, and holistic care approaches. Conclusion Korean dermatologists adopt individualized strategies for rosacea, yet practice gaps remain regarding neurogenic symptoms, pigmentary complications, and psychosocial and ocular comorbidities. Findings support the need for updated multidisciplinary, phenotype-driven guidelines aligned with real-world practice.

In patients with ossification of the posterior longitudinal ligament (OPLL), the risk of incidental durotomy (ID) during anterior cervical spine surgery is relatively high. However, the anterior surgical approach is technically demanding because of limited visualization and restricted operative space, which makes direct dural repair difficult. As a result, indirect repair techniques are typically employed, but these approaches can pose significant postoperative management challenges, particularly in cases of symptomatic cerebrospinal fluid (CSF) leakage. A 68-year-old male patient presented with right-sided symptoms involving both the upper and lower extremities. Radiological evaluation revealed C3–4–5 anterolisthesis, OPLL at the C4–5 level, and bilateral foraminal stenosis at C3–4 and C4–5. During anterior cervical discectomy and fusion (ACDF), an ID occurred at the anterior aspect of the C4–5 segment and was managed with primary indirect repair. Approximately 2 weeks postoperatively, the patient developed symptomatic CSF leakage. Under fluoroscopic guidance, a needle was precisely positioned adjacent to the interbody cage at the anterior aspect of the C4–5 segment—the site of the durotomy—to administer a targeted anterior epidural blood patch (EBP). The procedure was completed successfully without complications and resulted in effective resolution of the CSF leak. ID at the anterior aspect of the spinal canal during ACDF may lead to persistent symptoms due to CSF leakage. In such cases, a minimally invasive strategy, such as a targeted anterior EBP performed under fluoroscopic guidance, may represent an effective alternative to surgical re-exploration for symptom resolution.

Transforaminal endoscopic lumbar foraminotomy (TELF) is widely performed as a full-endoscopic surgical procedure for the treatment of lumbar foraminal stenosis. The technique involves the use of a small-caliber endoscopic system introduced through Kambin triangle to accomplish the primary surgical steps. However, anatomical barriers are frequently encountered in the lower lumbar segments, particularly at L4–5 and L5–S1, which may limit the feasibility of the transforaminal approach. Although various advanced transforaminal techniques have been developed to overcome these anatomical barriers, these techniques often make the procedure more technically demanding and may prolong operative time. In this video presentation, we report 2 cases in which a full-endoscopic paraspinal lumbar foraminotomy was performed to achieve adequate decompression of the exiting nerve root (ENR) without being constrained by these anatomical limitations. We also outline the procedural details and technical characteristics of this approach. Both patients presented with lumbar foraminal stenosis at the L5–S1 level, where anatomical barriers such as a high iliac crest, large transverse process, and sacral ala were present. A full-endoscopic paraspinal foraminotomy was performed at this level using a large-caliber endoscopic system, allowing sufficient decompression of the ENR and resulting in marked relief of radicular leg pain. We report a surgical procedure for full-endoscopic paraspinal lumbar foraminotomy using a large-caliber endoscopic system that permits the use of instruments of various sizes and configurations. When applied in appropriate clinical scenarios, this technique may facilitate more convenient and expedited decompression of the ENR.

Radical cholecystectomy is the standard procedure for gallbladder (GB) cancer, offering the possibility of cure. Many surgeons have increasingly expanded surgical indications following the growing trend of robotic surgery in hepatobiliary and pancreatic surgery. This study presents our experience with several robotic single-port (SP) plus one-port radical cholecystectomies using the da Vinci system (Intuitive Surgical). Data from five patients who underwent robotic SP radical cholecystectomy for GB cancer between April 2024 and December 2024 were retrospectively reviewed. All patients presented with imaging findings suggestive of localized GB cancer (T2 or lower). The median operative time was 145 minutes (range, 121–153 minutes), and the median number of harvested lymph nodes was five (range, five to eight). The median hospital stay after surgery was 6 days (range, 6–7 days), with no major complications reported. Robotic SP radical cholecystectomy is a safe and feasible option for GB cancer.

Gastroesophageal reflux disease (GERD) is a chronic and relapsing gastrointestinal disorder characterized by the reflux of gastric contents into the esophagus, leading to troublesome symptoms and/or complications. Since the publication of the 2020 Seoul Consensus on GERD, significant new evidence has emerged, particularly regarding acid-suppressive therapies and diagnostic approaches. This 2025 focused update aims to refine GERD management strategies by incorporating the latest evidence on acid suppressive therapies and regional considerations in Asian populations. This study builds on the 2020 Seoul Consensus by integrating systematic reviews, meta-analyses, and expert consensuses to offer updated recommendations for the definition and medical treatment of GERD. These guidelines incorporate recent advances in acid-suppressive therapies, particularly potassium-competitive acid blockers, and adopt updated diagnostic frameworks in accordance with the Lyon Consensus 2.0. Key clinical questions were identified and structured using the following format: Population, Intervention, Comparator, Outcome. The resulting recommendations address the initial treatment, long-term maintenance strategies, and role of personalized therapy based on disease severity, such as the grade of reflux esophagitis. Six key statements are presented: updated definition and classification of GERD (Statement 1); initial and long-term treatment strategies tailored to GERD phenotypes, such as non-erosive reflux disease, mild erosive esophagitis, and severe erosive esophagitis (Statements 2-5); and dose optimization strategies for long-term safety (Statement 6). These guidelines aim to support gastroenterologists and general healthcare providers in making individualized evidence-based decisions for GERD management.

Objective: Although most gallbladder polyps are benign, some neoplastic polyps may be malignant or may serve as precursors to malignancy. Distinguishing neoplastic and non-neoplastic polyps using imaging examinations remains a major challenge.This meta-analysis aimed to identify the ultrasound (US) features that are significantly associated with neoplastic polyps. Materials and Methods: The MEDLINE, EMBASE, Cochrane, and KoreaMed databases were searched for articles published up to August 31, 2025. Bivariate random-effects models were used to calculate the meta-analytic pooled diagnostic odds ratios (DORs), sensitivities, and specificities, along with their 95% confidence intervals (CIs), for each US imaging feature in the diagnosis of neoplastic polyps. Results: Thirty studies evaluating 8,953 patients, including 1,216 (13.6%) patients with neoplastic polyps, were included.Among the nine evaluated US imaging features, namely, size ≥10 mm, sessile morphology, single polyp, coexisting gallstones, hypoechogenicity, heterogeneous echogenicity, gallbladder wall thickening (GBWT), absence of hyperechoic spot, and vascularity, eight were significantly associated with neoplastic polyps: size ≥10 mm (DOR: 6.23 [95% CI: 1.86– 20.90]), sessile morphology (DOR: 3.54 [1.93–5.97]), single polyp (DOR: 2.21 [1.76–2.74]), coexisting gallstones (DOR:1.86 [1.29–2.60]), hypoechogenicity (DOR: 3.55 [1.47–7.30]), GBWT (DOR: 9.38 [1.47–32.20]), absence of hyperechoic spots (DOR: 4.23 [2.46–6.83]), and vascularity (DOR: 9.72 [5.81–15.30]). Of these, size ≥10 mm demonstrated the highest pooled sensitivity (0.79 [95% CI: 0.68–0.87]), whereas hypoechogenicity showed the highest pooled specificity (0.93 [95% CI: 0.82–0.98]). Conclusion Eight US imaging features (size ≥10 mm, sessile morphology, single polyp, coexisting gallstones, hypoechogenicity, GBWT, absence of hyperechoic spots, and vascularity) were significantly associated with the presence of neoplastic polyps.These features may facilitate the management of gallbladder polyps.

Objective: This study aimed to compare the therapeutic outcomes of no-touch (NT) radiofrequency ablation (RFA) vs. tumorpuncture microwave ablation (MWA) in the treatment of single hepatocellular carcinomas (HCCs) measuring ≤3 cm. Materials and Methods: This multicenter retrospective study included 304 patients who underwent either NT-RFA (n = 144) or MWA (n = 160) for a single HCC measuring ≤3 cm. Comparative analyses were conducted for the overall cohort, while 81 patients per group were matched using propensity score matching (PSM). The analyzed outcomes included technical success, primary technique efficacy, local tumor progression (LTP), and major complications. Cumulative LTP was estimated using Kaplan–Meier analysis and compared using the log-rank text, while the rate of ablative margin ≥5 mm and ablation time were compared using Chi-squared and Mann–Whitney U tests, respectively. Results: Technical success was achieved in 98.6% (142/144) and 100% (160/160) of in the NT-RFA and MWA patients, respectively before PSM (P = 0.224), and 98.8% (80/81) and 100% (81/81) after PSM (P = 1.000). The primary technique efficacies were 98.6% (142/144) and 100% (160/160) before PSM (P = 0.224), and 97.5 % (79/81) and 100% (81/81) after PSM (P = 0.497), respectively. The 1-, 2-, and 3-year cumulative LTP rates were 1.4%, 1.4%, and 2.3%, respectively, for NTRFA and 5.1%, 8.6%, and 8.6%, respectively, for MWA before PSM (P = 0.013). After PSM, the corresponding rates were 0%, 0%, and 0% for NT-RFA, and 7.6%, 10.4%, and 10.4% for MWA (P = 0.006). Major complications were not observed. NT-RFA achieved a higher proportion, with an ablative margin ≥5 mm (88.7% [126/142] vs. 71.9% [115/160]; P < 0.001), but required longer ablation times (median, 10.0 vs. 6.0 min; P < 0.001). Conclusion NT-RFA showed superior local tumor control compared to MWA, despite greater procedural complexity and longer ablation times.

Knee osteoarthritis (KOA) is a progressive and chronic musculoskeletal condition that continues to be the leading cause of disability worldwide. Conventional treatment approaches for the management of KOA largely focus on symptom alleviation rather than halting or reversing disease progression. However, recent advancements have highlighted the integrated interplay of mechanical stress, inflammation, cellular senescence, and chondrocyte dysfunction in the progression of KOA, in turn prompting new therapeutic strategies. Therefore, emerging interventions such as regenerative medicine, gene therapy, senolytic, platelet-rich plasma (PRP), disease-modifying osteoarthritis drugs (DMODs), and biologics have broadened the therapeutic options. Additionally, natural compounds demonstrated potential in KOA treatment with promising chondroprotective and anti-inflammatory effects.Moreover, digital technologies and clinical and molecular phenotyping enhanced early diagnosis, monitoring, and personalized management of the disease. Therefore, the current narrative review focuses on the molecular insights, clinical outcomes and prospects for the rapidly evolving landscape of current and emerging treatment approaches for the management of knee osteoarthritis (KOA).

Subglottic stenosis (SGS) and tracheal stenosis (TS) are rare conditions that can cause significant breathing difficulties and, if not properly managed, may lead to life-threatening complications. Despite their clinical importance, debate continues regarding the optimal management of adult SGS and TS, and no comprehensive guidelines have been established to date. The Korean Bronchoesophagological Society appointed a task force to develop clinical practice guidelines with the goal of providing evidence-based recommendations for managing SGS and TS in adults. The task force conducted a systematic review of the relevant literature by searching PubMed, Embase, and the Cochrane Library using predefined search terms aligned with key clinical questions. The quality of evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach, which also informed the formulation and reporting of the recommendations. The strength of each recommendation reflects the guideline panel’s confidence that the benefits of an intervention outweigh its risks for eligible patients. After drafting the guidelines, feedback was obtained through Delphi questionnaires completed by members of the Korean Bronchoesophagological Society. Ultimately, the committee developed 17 evidence-based recommendations across four categories: initial evaluation, medical management, surgical treatment, and postoperative management and rehabilitation. These guidelines aim to support clinicians in delivering optimal care to adult patients with SGS and TS.
