Purpose: Despite the widespread use of liquid skin adhesives (LSA), concerns persist regarding the increase in wound care costs. This study aimed to investigate the cost-effectiveness of LSA for surgical wound management. Methods: In this prospective, open-label, single-center randomized controlled trial, adults aged 19 years and older who were scheduled for elective minimally invasive colorectal surgeries were included. The participants were randomly divided into 2 groups: an n-butyl cyanoacrylate skin adhesive was used in the experimental group (LSA group), while a surgical skin stapler was employed in the control group (stapler group). The primary outcome measure was the sum of the total time required for wound management. Results: A total of 58 patients were randomly assigned to 2 groups, with 29 patients in each group. The findings revealed comparable wound complication rates in the 2 groups (8 out of 29 in the LSA group vs. 5 out of 29 in the stapler group, P = 0.530). Notably, the LSA group had a significantly shorter wound management time (median 235 seconds vs. 1,201 seconds, P < 0.001) and similar wound management cost (median US dollar [USD] 50.6 vs. USD 54.6, P = 0.529) compared to the stapler group. Subgroup analysis showed that the LSA group had a shorter management time for uncomplicated wounds and a lower cost for complicated wounds. Conclusion LSA not only provides a safe alternative but also offers a resource-efficient option for wound management compared to staplers.

Objectives: To assess the trends and disparities in the utilization of F-18 fluorodeoxyglucose positron emission tomography/ computed tomography (FDG PET/CT) in Korea between 2018 and 2022, with a focus on disease classification, patient demographics, and regional distribution. Methods: This national surveillance retrospective study uses data from the Health Insurance Review and Assessment Service (HIRA) database, which includes all FDG PET/CT examinations conducted in Korea from 2018 to 2022. Disease classifications, cancer types, age groups, gender, and geographic regions were analyzed using descriptive statistics. Utilization rates per 100,000 population were calculated for regional comparisons. Results: FDG PET/CT utilization increased by 25.4%, from 174,885 examinations in 2018 to 219,377 in 2022. Older age groups (60 years and above) accounted for the majority of examinations, with males undergoing more examinations than females. Oncology remained the primary indication, with lung, colorectal, and non-Hodgkin lymphoma leading in examination numbers. The number of examinations performed on patients aged 60 and above increased at a higher rate compared to those under 60. Significant geographic disparities were found, with Seoul reporting the highest utilization rate (1,114.3 examinations per 100,000 population), while Gyeongbuk exhibited much lower rate (26.2 examinations per 100,000 population). Conclusions This study highlights the growing utilization of FDG PET/CT in Korea, particularly among older adults, with significant gender differences in cancer types. The findings also reveal disparities in FDG PET/CT utilization across regions, indicating varying access to advanced imaging technology.

Background: This study was designed to determine the current status of diagnosis and treatment of valvular heart disease (VHD) in Korea. Methods: A nationwide registry study was conducted in 45 hospitals in Korea involving adult patients with at least moderate VHD as determined by echocardiography carried out between September and October of 2019. Of a total of 4,094 patients with at least moderate VHD, 1,482 had severe VHD (age, 71.3 ± 13.5 years; 49.1% male). Echocar‑ diographic data used for the diagnosis of each case of VHD were analyzed. Experts from each center determined the diagnosis and treatment strategy for VHD based on current guidelines and institutional policy. The clinical out‑ come was in-hospital mortality. Results: Each valve underwent surgical or transcatheter intervention in 19.3% cases of severe mitral stenosis, 31.4% cases of severe primary mitral regurgitation (MR), 7.5% cases of severe secondary MR, 43.7% cases of severe aortic stenosis, 27.5% cases of severe aortic regurgitation, and 7.2% cases of severe tricuspid regurgitation. The overall inhospital mortality rate for patients with severe VHD was 5.4%, and for secondary severe MR and severe tricuspid regur‑ gitation, the rates were 9.0% and 7.5%, respectively, indicating a poor prognosis. In-hospital mortality occurred in 73 of the 1,244 patients (5.9%) who received conservative treatment and in 18 of the 455 patients (4.0%) who received a surgical or transcatheter intervention, which was significantly lower in the intervention group (P = 0.037). Conclusions This study provides important information about the current status of VHD diagnosis and treatment through a nationwide registry in Korea and helps to define future changes.
