ABSTRACTQuantifying restoration success is a key objective for the UN Decade on Ecosystem Restoration. We evaluated the potential of acoustic indices to predict the recovery success of bird communities within abandoned agricultural areas in a biodiversity hotspot in Ecuador. Using audio recordings from a lowland tropical forest region, we identified 334 bird species and calculated established acoustic indices. Community composition was analyzed using Hill numbers, accounting for incomplete sampling. Acoustic indices effectively predicted verified species data (R2 = 0.59–0.76), capturing not only taxonomic but also functional and phylogenetic composition. Taxonomic composition was best predicted for common and dominant species, while functional and phylogenetic composition was more accurately predicted for rare and common species. Our findings demonstrate that a small set of acoustic indices, once validated by stratified ground truth data, provides a powerful tool for assessing restoration success over large tropical areas, including functional composition of rare tropical birds.

ABSTRACTBackgroundIn recent decades, parents are highly concerned for improving the cosmetic effectiveness of primary teeth restorations.AimTo assess and evaluate the success of the endodontic treatment in primary mandibular molars restored with zirconia crown and bulk-filled (BF) composite resins.Materials and methodsIn this split-mouth randomized controlled trial, 25 children aged 4–8-year-old were randomized into zirconia and BF groups. The endodontic treatment success and survival of restorations were evaluated using Kaplan–Meier and Cox regression analysis.ResultsSurvival rate was 88% in zirconia and 84% in BF for interradicular radiolucency, and the survival rate was 92% in zirconia and 88% in BF for periapical radiolucency. The survival rate difference between the two categories was 4% in both groups. The assumed noninferiority margin was 15%; according to that, in terms of endodontic success, the BF method was noninferior to the zirconia crown. The study failed to show the noninferiority of BF in terms of survival of restorations.ConclusionThe survival rate of endodontic treatment of BF was noninferior to zirconia, so BF can be considered as a postendodontic esthetic restoration in coronally restorable teeth.Clinical significance(1) BF composite resin can be used as a postendodontic restoration to satisfy the esthetic demand in developing countries like India. (2) Failure in BF restorations can lead to inadequacy in endodontic treatment.How to cite this articleZacharia NA, Paulindraraj S, Ramkumar H, et al.

The success of adhesive restorations largely depends on the optimal bond strength between the tooth structure and the restorative material. The aim of this study was to evaluate the shear bond strength (SBS) of four different adhesives applied to mandibular molars on deep and superficial dentin. The total of 56 teeth used in the study were randomly divided into 2 subgroups of superficial dentin and deep dentin participants (n = 28). Superficial and deep dentin groups were randomly divided into 4 subgroups (n = 7) for application with different adhesive agents. We formed the following groups: Group 1 (G1)-deep dentin and GC bonding agent (G-Premio BOND); Group 2 (G2)-superficial dentin and GC bonding agent; Group 3 (G3)-deep dentin and Clearfil S3 bond bonding agent (Clearfil TM S3 BOND); Group 4 (G4)-superficial dentin and Clearfil S3 bond bonding agent; Group 5 (G5)-deep dentin and KerrOptibond bonding agent (KerrOptibondTM Universal); Group 6 (G6)-superficial dentin and Kerr Optibond bonding agent; Group 7 (G7)-deep dentin and 3M-ESPE universal bonding agent (3M ESPE); Group 8 (G8)-superficial dentin and 3M-ESPE universal bonding agent. The silicone block with a diameter of 3 mm and a thickness of 1 mm was placed in the middle of the occlusal surface and the test composite was loaded. All prepared specimens were aged in thermal cycles at 5-55 °C for 5000 cycles. The teeth were subjected to SBS (shear bond strength) tests at a crosshead speed of 1 mm/min in a universal testing machine. In all adhesive systems, deep dentin showed a higher bond strength than superficial dentin and the bond strength value was statistically significant (p = 0.05). The bond strength in all tested adhesive systems was observed to be significantly higher in deep dentin than in superficial dentin.

ABSTRACTAimsRecreational use on mountain summits has caused severe degradation of soils and vegetation, and climate change is exacerbating these impacts. Best practices for restoration of these important ecosystems are unknown. Here, we examine the effectiveness of different treatments for restoring native vegetation (plant cover and native species richness) in degraded areas on a mountain summit through an experimental restoration approach.LocationCadillac Mountain, Acadia National Park, Maine, USA.MethodsWe tested six restoration‐method treatments: control, planting modules, coir erosion control, seed and coir, soil and coir, and soil, seed, and coir. We established four replicates of each restoration‐method treatment in 2016 and monitored percent cover and species richness twice per year from 2017 to 2022. In 2017, we established four more plots for each of three soil‐depth treatments (2.5 cm soil, seed, and coir, 13 cm soil and coir, and 13 cm soil, seed, and coir) and monitored percent cover.ResultsSix years after restoration began, native vegetation cover was highest in treatments with added soil. Seeding (502 seeds/m2) had no effect on percent cover. Planting seedlings added vegetative cover initially, but did not increase over time. Cover was equally high in treatments with shallow soil (2.5 cm deep) and deep soil (13 cm deep). Treatments with added soil also had the highest native species richness. Adding a small amount of soil (2.5 cm soil depth) with erosion control (i.e., coir matting) successfully restored vegetation to previously degraded areas of the Cadillac Mountain summit.ConclusionsMountain ecosystems will continue to experience degradation from human recreation and climate change. Restoration of degraded areas is critical to maintain these rare ecosystems. Our results suggest that restoring and maintaining soil is key to restoring degraded areas. However, more research is needed to understand the long‐term implications and success of mountain summit restoration. Our study provides an example of how this work can be done without delaying restoration using an experimental restoration approach.

All-ceramic crowns have gained immense popularity in modern day dentistry owing to their enhanced aesthetics, biocompatibility, and durability. Among these, lithium disilicate (LS2 ), zirconia (Z), and zirconia-reinforced lithium silicate (ZLS) are three most desired restorative materials, each offering varying benefits. The advances of material science and digital dentistry are constantly refining their clinical behaviour, making material selection a major part of restorative decision making. This review article provides a general summary of these three all-ceramic crown materials and discusses their evolution, specifically the development in the translucency of zirconia and the transformation of ZLS as a hybrid material. It covers the most important properties of each of these materials, such as aesthetics, biocompatibility, strength, and bonding procedures. It also discusses the effect of traditional vs. computerised impression methods on their clinical success. A lot of this review also contrasts traditional and digital impression technology. It discusses how developments such as intraoral scanning (IOS) and Computer-Aided Design and Computer-aided Manufacturing (CAD/CAM) technology impact the accuracy, efficiency, and clinical success of crown restorations. Through critical examination of the literature, this review is intended to provide clinicians with information necessary for evidence-based decision making in material selection and impression-taking techniques, which will ultimately maximise patient outcomes and long-term restorative success.

ABSTRACTIdentifying suitable donor sites is an important component of successful restoration and reduces the likelihood that a restoration action will have negative impacts on surrounding populations. Whether the most suitable donor site has (1) fast‐growing phenotypes, (2) high genetic diversity, or (3) harbors alleles that are beneficial for the current or future environment at the restoration site is an ongoing debate in restoration genomics. It is also debated whether one single donor site is the best choice, or if a mixed provenance strategy from sites with different characteristics is preferable. For eelgrass restoration, donor material is typically sourced within a few kilometers. It is therefore also this small spatial scale that needs to be considered when testing which local meadows harbor the most beneficial donor material for a given restoration site. We here assessed micro‐habitat differences at 10 eelgrass meadows across 1.5–14 km and genotyped the 10 meadows at 1689 single nucleotide polymorphisms (SNPs). We observed substantial differences in temperature regimes, genetic differentiation, and genetic diversity. We found that even on this small scale, 10% of the overall genetic variation was explained by the local environment of the meadow as well as geographic distance and genetic differentiation. We also identified putative adaptive loci associated with environmental variables and detected differences in growth in common‐garden mesocosm experiments simulating ambient summer conditions as well as a marine heatwave with concurrent freshening. We highlight that the variation in environment, genetic diversity, local adaptation, the potential for preadaptation for future conditions, and differences in individual growth can be strong in eelgrass meadows even on the small spatial scale. We suggest a donor registry to take into account these differences and narrow down the pool of potential donor meadows to source the most beneficial combination of donor material for any given restoration site.

Introduction: Internal Root Resorption (IRR) is the gradual deterioration of dentine due to clastic activity, typically appearing as a radiolucent area in the radicular dentine in communication with the root canal. Bioceramic materials such as Mineral Trioxide Aggregate (MTA) and Biodentine are available to restore the resorption cavity, offering biocompatibility and better sealing to the dentine. The present study employs the Finite Element Analysis (FEA) method to simulate stress behaviour, providing valuable insights into the effectiveness of these materials in reducing stress concentrations and reinforcing structurally compromised teeth. The findings aim to support clinical decision-making for achieving long-term restoration success. Aim: To evaluate and compare the stress distribution patterns in tooth models with IRR restored with MTA and Biodentine at the apical, middle and coronal thirds, employing FEA. Materials and Methods: This FEA study was conducted in the Conservative Dentistry and Endodontics department at Sibar Institute of Dental Sciences in Guntur, Andhra Pradesh, India, from June 2024 to August 2024. Seven three-dimensional (3D) FEA models of mandibular first premolars were designed: M1 (IRR at apical third restored with MTA), M2 (IRR at middle third restored with MTA), M3 (IRR at cervical third restored with MTA), M4 (IRR at apical third restored with Biodentine), M5 (IRR at middle third restored with Biodentine), M6 (IRR at cervical third restored with Biodentine) and M7 (control model). A force of 300 N was applied to the buccal side at a 30° inclined angle to the occlusal plane. Linear analysis was conducted to assess the Von Mises stress values along the central XY plane of the tooth model. The maximum and minimum Von Mises stresses were recorded and directly compared for each virtual tooth model. Results: Stress analysis showed maximum stress concentrations near the edges of the resorption cavities for both materials. In MTA-filled models, peak stress values were 73.35 MPa (apical), 104.35 MPa (middle) and 102.79 MPa (coronal), while Biodentinefilled models showed slightly lower peaks at 72.33 MPa (apical), 103.65 MPa (middle) and 101.86 MPa (coronal). Minimum stress values ranged from 0.0002 MPa to 0.0022 MPa across models, primarily in regions distant from the cavities. Conclusion: Biodentine exhibited slightly better stress redistribution than MTA, with lower peak stress values across all resorption levels; however, both materials left the cavity edges as critical stress concentration zones. These findings emphasise the need for additional restorative measures to address structural vulnerabilities.

Marginal and internal fit accuracy are critical factors for the success of indirect restorations. With advancements in Liquid Crystal Display (LCD)-based 3D printing technology, this study evaluates the effects of build angle and preparation margin design on the accuracy of 3D-printed resin composite overlays. This study aims to analyze differences in the marginal and internal fit accuracy of 3D-printed resin composite overlays based on build angle (150° and 180°) and preparation margin designs (shoulder and functional cusp bevel). This experimental study used 40 overlay samples divided into four groups based on combinations of build angle and preparation margin design. Marginal and internal fit accuracy was assessed using the silicone weight technique, and using the silicone replica technique with a digital optical microscope. Data were statistically analyzed using Two-way ANOVA and Post Hoc Tukey tests. Build angle statistically influenced both marginal and internal fit accuracy (p<0.05). The 180° angulation group showed better results compared to 150°. Preparation margin design did not significantly affect internal fit accuracy, although the functional cusp bevel design exhibited larger marginal gaps than the shoulder design in specific measurements. Conclusion: The build angle affects the marginal and internal fit accuracy for 3D-printed resin composite overlays using the LCD method and 180° yields better marginal and internal fit accuracy. Preparation margin design did not significantly affect internal fit accuracy.

Post-mining land rehabilitation is an important strategy to mitigate climate change and conserve tropical ecosystems. Surface mining activities in East Kalimantan have caused ecological degradation and the release of carbon stored in vegetation and soils. Revegetation has been widely practiced as the main approach to restore ecosystem functions, including initial carbon accumulation by understory plants. This study aims to estimate the carbon stock of the understory on post-mining land that has undergone revegetation for one year at the PT Insani Baraperkasa site in Loa Janan, East Kalimantan. The method used was destructive sampling of understory biomass from 10 plots measuring 5 m x 5 m, each with subplots measuring 0.5 m x 0.5 m. Biomass samples were dried and converted to carbon. The results showed an average carbon stock of 1.26 tons/ha. These results suggest that understorey vegetation plays an important role in early stage carbon recovery on post-mining land. Understory carbon monitoring can be an effective early indicator to measure the success of ecosystem restoration. Keywords: revegetation, understorey, post-mining, carbon

Coal mining activities have caused severe environmental degradation, particularly in the form of soil structure damage, loss of natural vegetation, and a decline in soil organic carbon (SOC) reserves. This study aimed to evaluate the amount of SOC stock as an indicator of restoration success and its contribution to long-term carbon stock. Soil sampling was conducted in a post-mining area under a 10-year-old Acacia mangium stand at PT. Ratu Samban Mining, Batu Beriang Village, Pematang Tiga District, Central Bengkulu Regency, Bengkulu Province, at depths of 0–10 cm, 10–20 cm, and 20–30 cm. The samples at each depth were analyzed for SOC content, pH, bulk density, and soil texture (percentages of sand, clay, and silt). Statistical analyses used were ANOVA, regression, and correlation. The results showed SOC stock of 23.70 Mg ha⁻¹, 20.75 Mg ha⁻¹, and 16.88 Mg ha⁻¹ at depths of 0–10 cm, 10–20 cm, and 20–30 cm, respectively. These values are close to the SOC stock of secondary forests (28.5 Mg ha⁻¹). In addition, clay content and soil pH had significant correlations with SOC. Reclamation through 10 years of revegetation using A. mangium stands effectively increased SOC stocks.

Metformin is commonly used to manage type 2 diabetes (T2D) and is being investigated for its potential antiproliferative effects in cancer, particularly in patients with both T2D and malignancies. Drug resistance can develop with any therapeutic agent, and metformin is no exception. As we showed in our previous study, metformin-resistant MDA-MB-468 (MET-R) cells exhibited an EMT-like phenotype. Many transcription factors, as well as miRNAs, can contribute to this altered phenotype. Our current study identifies the contribution of hsa-miR-26a-5p expression to the previously observed phenotype. By utilizing bioinformatic tools, we identified hsa-miR-26a-5p, whose expression was significantly altered with increasing concentrations of metformin in MET-R cells. We rescued hsa-miR-26a-5p expression and examined the EMT phenotype and apoptotic markers via Western blot analysis. We observed a reduction in hsa-miR-26a-5p expression in response to increasing concentrations of metformin in MET-R cells. Upon successful restoration of hsa-miR-26a-5p expression, a subsequent decrease in the proliferation rate was noted. Moreover, when combined with a PI3K inhibitor, we observed increased sensitivity to the PI3K inhibitor. The EMT and apoptotic markers also tended to decrease upon combinatorial treatment. In this study, we rescued the diminished expression of hsa-miR-26a-5p in MET-R cells to increase the sensitivity to PI3K inhibitor. The combination of a PI3K inhibitor and rescued hsa-miR-26-5p expression resulted in the restoration of the EMT phenotype and proliferation in these cells.

Introduction: Coronal restoration following endodontic therapy is critical for success. Restorations after endodontic treatment should minimize fractures of residual hard tissues, and leaks, and maintain dental function. The aim of this study was to evaluate the success of post-endodontic restorations using various restorative materials over a two-year period. Methods: The study involved 60 individuals aged 18 to 40. The patients were randomly divided into three groups. Conventional composite restorations were used to restore the first group. The second group was treated with a fiber-reinforced composite covered in composite resin. The third group was reconstructed using endocrowns. The restorations were prospectively investigated for two years. Results: In the composite restoration group, two restorations and one tooth were fractured, with two polishable surfaces found on one restoration surface. In the fiber-reinforced resin-supported composite restoration group, one restoration fragmented and one polishable surface was found. In the endocrown restoration group, 2 endocrowns had decementation. No significant difference was observed in periodontal examination including gingival pocket depth, plaque index and bleeding index assessment (p> 0.05). There were no marginal discrepancies and no caries in any of the restorations. At the last appointment, patient satisfaction was evaluated aesthetically and functionally using a visual analog scale. Conclusion: All groups had a 100% survival rate over the two-year follow-up period. According to the patients, there was no functional difference between the restoration groups (p> 0.05); however, aesthetically, restorations with endocrowns were more successful (p

Background and Objectives: Ensuring the optimal shear bond strength (SBS) is essential for the long-term success of prosthodontic restorations. Our in vitro study aimed to evaluate the SBS of three types of ceramics (feldspathic, alumina, and lithium disilicates) using three adhesive cements (Variolink Esthetic LC, Variolink Esthetic DC, and Maxcem Elite). Materials and Methods: Healthy molars were prepared, and ceramic blocks were cemented following universally accepted luting protocols. SBS tests were performed using a custom-made testing machine. A multiple linear regression model assessed the effects of ceramic type, surface treatment, and luting agent on SBS. Results: The regression model explained 61.3% of the variation in SBS values (R2 = 0.613); the adjusted R2 = 0.605 confirmed the model’s robustness. The global F-test was statistically significant (F = 78.96, p < 0.001). The total-etch technique (+4.47), the use of feldspathic ceramic, and 5% hydrofluoric acid treatment (+3.28) significantly affected SBS. Feldspathic ceramic and lithium disilicate showed superior performance against alumina. Light-cured and self-cured cement showed negative effects. Conclusions: Ceramic material and cement type have combined effects on SBS. Optimal results were obtained with the total-etch technique, feldspathic ceramic, 5% hydrofluoric acid treatment, and dual-cured cement.

Oysters, Crassostrea virginica, are economically and ecologically valuable but have severely declined, and restoration is needed. As with the restoration and aquaculture of many shellfish species, restored oyster reefs are often impeded by predation losses, reducing restoration success and restricting locations where restored reefs are viable. Like many organisms, shellfish can modify their morphology to reduce predation risk by detecting and responding to chemical signals emanating from predators and injured prey. Oysters grow heavier, stronger shells in response to predation risk cues, which improves their survival. We tested if using predator cues to trigger shell hardening in oysters could be performed over a scale suitable for oyster reef restoration and improve oyster survival long‐term. We constructed an intertidal oyster reef using oysters grown in a nursery for 4 weeks while exposed to either exudates from Blue crab (Callinectes sapidus) predators or grown in controls without predator cues. Oysters grown with predators were 65% harder than those grown in controls, and after 1 year in the field, had a 60% increase in survival. Predation losses on the restored reef were significant, and the benefit of predator induction for survival was highest at intermediate tidal elevations, presumably due to intermediate levels of predation and abiotic stress. Our results suggest that manipulating the morphology of cultivated or restored species can be an effective tool to improve survival in habitats where consumers impede restoration success.

Ongoing ecosystem degradation and loss demand restoration efforts worldwide. In Central Europe, semi‐natural grasslands are in focus, and better understanding of restoration success and its drivers is needed. For practical projects, systematic screening remains lacking. We compared plant species composition of 41 recipient sites 3–18 years after restoration via plant material transfer with composition of their donor sites. Further, we analyzed establishment of habitat‐typical and endangered species. Spanning a gradient of moisture conditions, sites were located in Germany and Luxembourg. Soil characteristics, biomass productivity, and restoration setup (e.g. previous site state, age) were investigated as potential drivers of success. In dry grasslands, success was highest, likely due to the creation of raw soils at several sites before plant material application. While raw soils generally favored the establishment of endangered species, the resulting low‐productive and dry conditions sometimes posed challenges for mesic grassland restoration. In mesic grasslands, elevated soil pH of some recipient sites further contributed to divergence in species composition compared to donor sites. In alluvial grasslands, high nutrient and productivity levels of recipient sites impeded restoration success. Wet grasslands were successfully restored when soil moisture was sufficient. Across grassland types, species richness decreased with time since restoration, yet the number and cover of habitat‐typical and endangered species remained stable. Introducing typical species in addition to plant material transfer supported restoration. We advocate for large‐scale, systematic investigations of practical grassland restoration projects combined with well‐defined monitoring guidelines across different regions to address this complex challenge in the coming decades.

Proper polymerization protocol is crucial for the long-term success of full-ceramic crown restorations. This study investigates the margin continuity and degree of conversion (DC) of a universal dual-curing cement under full-ceramic crowns subjected to different polymerization protocols and thermal aging. Intact human upper central incisors and canines were prepared for crowns, digitally designed, and milled from reinforced lithium silicate (Celtra Duo, Dentsply). Crowns were cemented using a universal dual-curing cement (G-Cem One, GC) with two polymerization protocols: (G1) microbrush excess removal, 1 min waiting, and 20 s light curing per side; (G2) 5 s tack curing per side, excess removal with a scaler, and 20 s light curing. Marginal adaptation was assessed using micro-computed tomography, and DC was evaluated with Raman spectroscopy before and after artificial thermal aging (10,000 cycles between 5 °C and 55 °C). Statistical comparisons were performed with significance set at p < 0.05. Results showed significantly poorer marginal adaptation in the tack-curing group, with no post-aging differences between groups. Baseline DC was high in all samples, with no protocol-dependent variations; nevertheless, aging increased DC in G1. These findings highlight the importance of selecting an appropriate polymerization protocol to ensure optimal marginal adaptation and polymerization efficiency.

Ngong River is a vital water resource which is heavily polluted due to improper waste disposal. Despite restoration programmes that have been ongoing for decades and efforts to develop and implement restoration strategies such as integrated system of solid waste management, little has been achieved. This study aimed at investigating the effectiveness of stakeholder’s roles in solid waste management and their contribution to the successful restoration of Ngong River. Purposive sampling method was used in selection of 30 officials for the study. This approach permitted for target selection which ensured inclusion of only key stakeholders in the study, who participated directly in solid waste management, implementation of policies and restoration of river. Institutional questionnaires and key informant interviews were used to collect the information from the respondents and result presented in tables, graphs and charts. The findings revealed that, restoration of Ngong River entailed multiple stakeholders engaged in diverse solid waste management activities, primarily focused on public awareness and education (36%), waste collection (31%), and recycling initiatives (14%). Government agencies and NGOs/CBOs collaborate to implement policies and provide technical support, but challenges such as inadequate funding, poorinfrastructure, and inconsistent waste collection hinder effective management. Among the stakeholders, Nairobi City County Government was rated most ineffective (75%) in waste collection and disposal services. Solid waste management in restoration of Ngong River restoration necessitates collaboration among government agencies, Nairobi County, NGOs, CBOs, and local communities, despite challenges. Holistic approach should be applied in improving solid waste management in restoration of heavily polluted Ngong River restoration.

Dental restoration failure is one of the major problems faced in dentistry and results in further treatment requirements, dissatisfaction by the patients, and increased costs. Therefore, a thorough knowledge of causes and consequences of restoration failure is necessary for designing effective preventive measures. Objective: The present study aimed to determine the causes and consequences leading to restoration failure and eventually develop prevention strategies. Methodology: This cross-sectional study was conducted in a dental clinic setting. Dental records of 100 middle-aged patients (25-50 years) from restoration failure were used for the record review study. Standardized Dental Record Extraction Form (SDREF) was used to extract the relevant clinical and demographic data. Patient Satisfaction Questionnaire (PSQ) was used to assess the satisfaction levels of patients with their dental restorations. Descriptive statistics and logistic regression were used for data analysis to determine factors associated with restoration failure. Results: The study reveals that 62% of those restoration failures are due to poor oral hygiene, 22% to inadequate restoration design, and 16% due to material failure. The logistic regression analysis demonstrated that a significant association was found between restoration failure and poor oral hygiene (OR=2.3, p&lt;0.001). Results revealed that patient satisfaction was significantly lower among subjects experiencing restoration failures (mean: 2.9 vs. 4.1, p &lt; 0.001). Conclusion: This study emphasized the importance of accurate restoration design, material, and the maintenance of acceptable oral hygiene standards in hindering restoration failure. The results will aid in developing evidence-based strategies to enhance restoration success rates and improve the patients' conditions.

The purpose of this study was to assess the efficacy and safety of self-expandable metal stents (SEMS) in treating anastomotic obstruction associated with recurrent gastric cancer. Ten patients with anastomotic obstruction in recurrent gastric cancer were treated by SEMS implantation under fluoroscopic guidance. All patients presented with refractory nausea, vomiting and complete inability to tolerate oral intake before stent placement, requiring total parenteral nutrition (TPN). Clinical data were retrospectively analyzed the technical and clinical success rates, stent patency and complication rates. SEMS was successfully implanted in all patients, and clinical success rate was 100%. The operations were subtotal gastrectomy with Billroth-II reconstruction (n = 3), radical distal gastrectomy (n = 3), total gastrectomy with esophagojejunostomy (n = 3), and palliative gastrojejunostomy (n = 1). Three patients developed stent occlusion due to intrastent tumor ingrowth secondary to disease progression after initial anastomotic stent placement, and underwent secondary stent implantation with successful maintenance of patency postoperatively. One patient developed stent obstruction due to food impaction on postoperative day 10, which was managed endoscopically with successful restoration and maintenance of luminal patency. The mean stent patency was 78d (range, 8-225 d). No serious complications, such as anastomotic leakage, stent migration and bleeding were observed in these patients. Fluoroscopically-guided SEMS placement represents a technically safe and clinically effective intervention for managing anastomotic obstructions in recurrent gastric cancer. SEMS placement offers rapid symptom relief, shorter hospital stays, and improved quality of life compared to surgical alternatives in this patient population. Thus, based on its technical feasibility and clinical outcomes, this method warrants primary consideration in palliative treatment algorithms.
