Abstract Background/Aims Alpha-fetoprotein (AFP) and des-gamma-carboxy prothrombin (DCP) have been used as diagnostic tools for hepatocellular carcinoma (HCC). However, prediction of outcome using AFP DCP has not elucidated. We investigated the clinical role predictors treatment in patients with HCC undergoing trans-arterial chemoembolization (TACE). Methods Between January 2003 December 2005, we enrolled 115 treatment-naïve who received TACE an initial modality. An or response was defined a...
This study aims to evaluate clinical outcomes of patients with hepatocellular carcinoma who underwent transarterial chemoembolization (TACE) using drug-eluting beads (DEB).This retrospectively compared the 250 consecutive DEB-TACE (n = 106) or conventional TACE (cTACE) 144) in a tertiary center between January 2010 and April 2014. The median age was 62 years 81.6% were men. primary endpoint overall survival (OS). time progression (TTP), radiological response rate modified evaluation criteria...
Abstract Very few population-based studies have examined the epidemiology of Wilson’s disease (WD). We investigated WD using National Health Insurance Service (NHIS) database in South Korea. analyzed not only statistical variables WD, but also those WD-related diseases. patients were identified with relevant International Classification Diseases-10 code out 50.5 million people. used NHIS from 2009 to 2016 and incidence rate, prevalence, clinical symptoms WD. A total 1,333 identified. The...
Background/Aims To investigate whether visceral fat area (VFA) measured by bioelectric impedance analysis (BIA) was associated with metabolic syndrome in subjects and without obesity. Methods A total 23,202 participants who underwent medical check-ups were assessed. Participants stratified body mass index (BMI) VFA. We evaluated six different groups for syndrome: Group 1 (normal weight low VFA), 2 high 3 (overweight 4 5 (obesity 6 VFA). Results Metabolic traits significantly more prevalent...
The prevention of post-endoscopic submucosal dissection (ESD) bleeding in high-risk patients is an important problem. This study evaluated the efficacy polysaccharide hemostatic powder preventing post-ESD patients.Patients at high risk for were prospectively enrolled between December 2015 and July 2016. A was considered if taking antithrombotic agents or had undergone a large resection (specimen size ≥ 40 mm). endpoints Forrest classification ulcer on second-look endoscopy 2 days after...
BACKGROUND The clinical trend and characteristics of peptic ulcer disease (PUD) have not fully been investigated in the past decade. AIM To evaluate changing trends PUD according to age etiology. METHODS We analyzed seven hospital databases converted into Observational Medical Outcomes Partnership-Common Data Model between 2010 2019. classified patients with who underwent rapid urease tests or Helicobacter pylori (H. ) serology three groups: H. -related, drug [nonsteroidal anti-inflammatory...
Humoral hypercalcemia of malignancy (HHM) is rarely associated with cholangiocarcinoma (CC), and represents dismal prognosis. A 63-year-old male was admitted for evaluation an intrahepatic mass. He diagnosed HHM locally advanced CC. As the tumor responded to concurrent chemoradiotherapy capecitabine cisplatin, serum calcium level normalized. However, according disease progression, he suffered recurrence expired approximately one year after initial diagnosis. 68-year-old who presented...
Conflicting results have been reported regarding the interaction between proton pump inhibitors (PPIs) and clopidogrel. We investigated whether concomitant PPI use influenced risk of recurrence in patients with stroke myocardial infarction (MI).This study used two databases for different designs, Korean National Health Insurance Service (NHIS) database a self-controlled case series design, national sample cohort NHIS data base converted to Observational Medical Outcomes Partnership-Common...
Background and Aims . Endoscopic submucosal dissection (ESD) is routinely performed in treating gastric neoplasia requires long-term higher levels of sedation. Endoscopist-directed nurse-administered sedation (EDNAS) has not been well studied ESD. This study aimed to evaluate the safety effectiveness EDNAS for Methods Patients treated with ESD tumors between 2013 2015 were retrospectively collected. divided into a midazolam-treated group (M group) midazolam plus propofol-treated (MP group)....
To estimate long-term outcomes after treatment modification in patients with chronic hepatitis B (CHB) treated entecavir (ETV) and telbivudine (LdT).The study enrolled 131 nucleos(t)ide analogue (NA)-naïve CHB ETV or LdT. During the 3-year study, NA history including incidence, type of modification, reasons for overall complete virologic response (CVR) rate were retrospectively evaluated using patients' medical records.Among patients, 84 47 initially LdT, respectively. course 82 group...
Background/Aims: This study aimed to compare the efficacy of a recently developed clear-cut knife with that widely used knives for endoscopic submucosal dissection (ESD) in early gastric cancer (EGC).Materials and Methods: Data were collected retrospectively from National Health Insurance Service Ilsan Hospital between May 2017 April 2019. The included 105 patients (108 lesions) EGC who underwent ESD. Fifty-six EGCs dissected using an insulation-tipped diathermic combination needle knife,...

A deep-learning-based approach for recognizing integrated circuit (IC) packaging type is presented in this paper. The objective of work to design a deep-learning method that can recognize multiple types per detection, performing counting operations, and calculating the centre location an IC with its tilting angle. transfer learning from model You-Only-Look-Once (YOLO) v5 was chosen because it has been trained coco dataset more reliable feature extraction system than other models. In order...
Background/Aims: Changing trends in the <i>Helicobacter pylori</i> (<i>H. pylori</i>) eradication protocol have not been investigated after publication of third-revised Korean guideline 2013. We aimed to analyze clinical characteristics <i>H. pylori</i>-infected patients alongside their treatment protocols using a common data model (CDM).Materials and Methods: A 16-year electronic health record (of 1,689,604 from 2004 2019) was converted into CDM Kangdong...
This is a case report of successful endoscopic resection (ER) bleeding duodenal lipoma.

Surgery has been the standard treatment for perforated duodenal ulcers, with mostly good results. However, resolution of postoperative leakage after primary repair ulcer remains challenging. There are several choices re-operation required in persistent from ulcers. many these complicated surgical procedures requiring prolonged general anesthesia that may increase chances morbidity and mortality. Several recent reports have demonstrated a treated endoscopic insertion using covered...
