연구실 소개
박원서 교수의 연구실은 미세외과적 내시경 경로를 활용한 갑상선 및 경부외과 수술의 최적화에 초점을 맞추고 있습니다. 특히 후두주변 및 견갑부를 이용한 미세외과적 접근법(예: PAA, TOETVA)을 통해 외모적 불만을 최소화하면서도 안정적인 수술 결과를 도출하고자 합니다. 또한 갑상선 수술 후 합병증 예측 및 암의 분자생물학적 기전 규명을 위한 임상 및 분자생물학적 연구도 병행하고 있습니다.

15BACKGROUND: While the bilateral axillo-breast approach (BABA) to endoscopic neck surgery resolves various benign and malignant thyroid and parathyroid diseases with minimal adverse effects and excellent cosmetic outcomes, it involves circumareolar incisions. Many patients, especially young female patients, are reluctant to have their breast involved. Consequently, we developed the postauricular and axillary approach (PAA) that uses postauricular incisions. METHODS: From June 2006 to December 200
Co-stimulation mediated by the CD28 molecule is considered critical in the activation of CD4+ T cells. In patients with rheumatoid arthritis and infrequently in normal individuals, CD4+ T cells lacking CD28 expression are expanded and contain clonogenic populations. To analyze whether these cells are independent of co-stimulatory requirements or whether they use co-stimulatory signals distinct from the CD28 pathway, we have compared CD4+ CD28+ and CD4+ CD28- T cell clones isolated from rheumatoi
Female gender (P = 0.001), extent of CND (P = 0.014), and PTG in permanent pathologic sections (P = 0.035) were found to be significant factors affecting the development of hypocalcemia. Despite some study limitations, we suggest that the relative changes in the serum levels of calcium (20%) and of phosphorus (40%) on the second postoperative day may be reliable predictors of post-thyroidectomy hypoparathyroidism.
BACKGROUND: Upregulation of SLC2A genes that encode glucose transporter (GLUT) protein is associated with poor prognosis in many cancers. In colorectal cancer, studies reporting the association between overexpression of GLUT and poor clinical outcomes were flawed by small sample sizes or subjective interpretation of immunohistochemical staining. Here, we analyzed mRNA expressions in all 14 SLC2A genes and evaluated the association with prognosis in colorectal cancer using data from the Cancer Ge
It is very difficult for operators to predict the progression of a loss of coolant accident (LOCA) because nuclear plant operators are provided with only partial information during the accident or they may have insufficient time to analyze the data despite being provided with considerable information. Therefore, its break location should be identified and the break size should be predicted accurately in order to provide the operators and technical support personnel with important and valuable in
The transoral endoscopic thyroidectomy vestibular approach (TOETVA) has excellent cosmetic effects and its popularity is increasing worldwide. We present our experience with TOETVA and its short-term outcomes. This study included 110 consecutive patients who underwent TOETVA at a single institution between July 2016 and June 2020. We analyzed clinicopathologic data, short-term postoperative outcomes, and learning curve using cumulative summation (CUSUM) analysis. Of the 110 patients who underwen
BACKGROUND: The purpose of this study was to compare the surgical outcomes of robotic thyroidectomy (RT) using bilateral axillo-breast approach (BABA) with conventional open thyroidectomy (OT) in papillary thyroid carcinoma patients. METHODS: Between January 2009 and December 2013, 815 patients who had received thyroidectomy for papillary thyroid carcinoma were enrolled. Of these, 126 patients received RT and 689 patients underwent OT. Age, gender, body mass index, extent of surgery, tumor size,
Hypoxia-related gene (HRG) expression is associated with survival outcomes of colorectal cancer (CRC). Our aim was developing a nomogram predicting CRC overall survival (OS) with HRGs and clinicopathological factors. The Cancer Genome Atlas (TCGA) database was used as discovery cohort and two Gene Expression Omnibus databases (GSE39582 and GSE41258) served as validation cohorts. A genetic risk score model prognosticating OS was developed using mRNA expression level of HRGs. Nomogram predicting O
The previous results and our experiences suggest that a second TUR is recommended to reduce the chance of residual tumor and staging error because of nonstandardized TUR in the patients referred to an academic or referral center for a second opinion, irrespective of previous tumor stage.
BRCA1/2 are breast cancer susceptibility genes that are involved in DNA repair and transcriptional control. They are dysregulated in breast cancer, making them attractive therapeutic targets. Here, we performed a systematic multiomics analysis to expound BRCA1/2 functions as prognostic biomarkers in breast cancer. First, using different web-based bioinformatics platforms (Oncomine, TIMER 2.0, UALCAN, and cBioportal), the expression of BRCA1/2 was assessed. Then, the R package was used to analyze
Peritoneal loose bodies (PLBs) are usually discovered incidentally during laparotomy or autopsy. A few cases of giant PLBs presenting with various symptoms have been reported in the literature. Here, we describe a case of a giant PLB incidentally found in the pelvic cavity of a 50-year-old man. Computed tomography revealed a free ovoid mass in the pelvic cavity that consisted of central dense, heterogeneous calcifications and peripheral soft tissue. The mass was an egg-shaped, hard, glistening c
Introduction: Oncological and surgical safeties are pivotal issues of cancer operations. Robotic thyroidectomy adds cosmetic advantage to those safeties. We have performed bilateral axillo-breast approach robotic thyroidectomies (BABART) since 2009 and recently started transoral robotic thyroidectomy (TORT) in 2017. This study aimed to compare the surgical outcomes of a single surgeon's initial TORT and BABART. Materials and Methods: We retrospectively collected data of 103 patients who underwen
A 59-year-old woman with classic manifestations of hyperparathyroidism associated with multiple endocrine neoplasia type 1 presented with a right adrenal mass and two pituitary microadenomas on imaging studies. For evaluation of hypercalcemia, (99m) Tc-MIBI scintigraphy was done and showed focal uptake at the thyroid level of the right anterior neck. Subsequent neck sonography showed several thyroid nodules, but there was no parathyroid tumor. Percutaneous fine-needle aspiration of the dominant
The chemical and magnetic states of Fe/Fe2O3 thin films prepared by e-beam evaporation were investigated by using element-specific techniques, X-ray absorption spectroscopy (XAS) and X-ray magnetic circular dichroism (XMCD). It was clearly shown that the Fe layers are oxidized to form an antiferromagnetic (AFM) FeOx<1, while the bottom oxide remained a weak ferromagnet (wFM) (α+γ)-type Fe2O3. Dependences of the peak intensities and lineshapes on the Fe thickness and measurement geometry furth
