Purpose: Laparoscopic colon surgery is now commonly used for colorectal cancer (CRC) resection. The objective of this study was to compare the oncologic outcomes between open conversion and laparoscopic surgery, and to identify risk factors for open conversion.
Methods: We retrospectively reviewed the medical records of patients who underwent curative resection for stage 0-III CRC at five Hallym University-affiliated hospitals between January 2011 and June 2021.

Objectives: To compare presurgical skeletal factors and postsurgical relapse patterns between more relapsed (MR) and less relapsed (LR) groups.
Materials And Methods: This study retrospectively examined patients who underwent mandibular setback surgery, classifying them into two groups based on the amount of relapse of the pogonion using K-means analysis. Comparisons were conducted by analyzing cephalometric radiographs presurgically (T0), at 1-month post-surgery (T1), and immediately after orthodontic treatment (T2).
Purpose: The COVID-19 pandemic has influenced various aspects of colorectal cancer (CRC) patient care, including diagnosis, treatment, and outcomes. This study assesses the pandemic's impact on CRC patients.
Methods: We performed a retrospective analysis of medical records for CRC patients who underwent surgery at five hospitals affiliated with Hallym University from January 2017 to December 2022.
Bovine abortion is a critical problem in the cattle industry. Identifying causes of abortion is key to establishing appropriate herd management and prevention strategies. We used pathology examinations, detection of etiologic agents, and serology to determine the cause of bovine abortions in Korea.

Although the paracrine effect of growth factors in stem cell therapy made it a promising angiogenic therapy for CLI, poor cell survival in the harsh ischemic microenvironment limited its efficacy. Thus, an imperative need exists for a stem-cell delivery method that enhances cell survival.

Methods: We retrospectively reviewed patients who underwent curative resection for T1 or T2 CRC at five University-affiliated hospitals between January 2012 and December 2021. The patients were divided into several groups depending on the presence of LNM or the number of risk factors.
Background: Oncologic impact of genetic alteration across synchronous colorectal cancer (CRC) still remains unclear. This study aimed to compare the oncologic relevance according to genetic alteration between synchronous and solitary CRC with performing systematic review.
Methods: Multicenter retrospective analysis was performed for CRC patients with curative resection.
Background: The objective of this study was to evaluate clinicopathologic features of young patients with colorectal cancer (CRC) and to compare their prognosis with those of older patients Methods: We retrospectively reviewed the medical records of patients who underwent surgery for stage 0-III CRC at four university-affiliated hospitals between January 2011 and December 2020. The patients were divided into two groups, the young adult group (≤45 years) and the older group (>45 years).
Results: Of 1992 patients, 93 (4.
Stem cell therapy has emerged as a promising regenerative medicine strategy but is limited by poor cell survival, leading to low therapeutic outcomes. We developed cell spheroid therapeutics to overcome this limitation. We utilized solid-phase FGF2 to form functionally enhanced cell spheroid-adipose derived (FECS-Ad), a type of cell spheroid that preconditions cells with intrinsic hypoxia to increase the survival of transplanted cells.

The differentiation of implanted human adipose-derived stem cells (hADScs) into SMCs in an IAS-targeting AI model has also not been demonstrated. We aimed to develop an IAS-targeting AI animal model and to determine the differentiation of hADScs into SMCs in an established model.

We aimed to evaluate the perioperative and oncologic outcomes of SEMS as a bridge to surgery in obstructive CRC, as compared with ES. We retrospectively reviewed the medical records of patients who underwent curative resection of obstructive CRC at four Hallym University-affiliated hospitals between January 2010 and December 2019.

Methods: Medical records of the consecutive patients who underwent LS or open surgery (OS) for PPU at five hospitals between January 2009 and December 2019 were retrospectively reviewed.

Big data can be used to correlate diseases and climatic factors. The prevalence of influenza (flu) virus, accounting for a large proportion of respiratory infections, suggests that the effect of climate variables according to seasonal dynamics of influenza virus infections should be investigated. Here, trends in flu virus detection were analyzed using data from 9,010 tests performed between January 2012 and December 2018 at Dankook University Hospital, Cheonan, Korea.

Methods: We retrospectively analyzed the medical records of patients aged ≥ 80 years who underwent curative resection of colorectal cancer at six Hallym University-affiliated hospitals.
Appendicitis is a common intra-abdominal inflammatory disease, and morbidity increases with age when perforation occurs. Because, not all patients require emergency surgery, there have been numerous studies on factors for predicting perforated appendicitis. In this study, we aimed to confirm whether the delta neutrophil index (DNI) and the time from symptom onset to surgery are effective predictors for perforated appendicitis in different age groups.

We developed inclusion criteria to optimize antibiotic therapy use and compared the success rate to that seen in previous literature.
Methods: Our antibiotic therapy inclusion criteria were developed based on clinical findings (symptom onset ≤48 hours and body temperature ≤38.
