This study was conducted to evaluate the clinical usefulness of PET/CT in differentiating autoimmune pancreatitis from pancreatic cancer.To differentiate cancer, we analyzed cases 17 patients with and atypical imaging findings who underwent integrated PET/CT. The on were compared those 151 cancer.Fluorine-18 FDG uptake by pancreas found all 82% (124/151) cancer. Diffuse significantly more frequent (53% vs 3%, p < 0.001). salivary glands kidneys seen only pancreatitis, former reaching...
This study aimed to determine longterm outcomes and factors associated with increased survival after photodynamic therapy (PDT) compared endoscopic biliary drainage alone in patients presenting advanced hilar cholangiocarcinoma (CC).A retrospective analysis of the institutional database identifying all who presented a diagnosis CC between December 1999 January 2011 was conducted.Of 232 identified, 72 (31%) were treated PDT (Group A) 71 B). Median 9.8 months [95% confidence interval (CI)...
Patients with cholangiocarcinoma usually present at an advanced stage, and more than 50% of cases are not resectable the time diagnosis. Recently, photodynamic therapy (PDT) has been proposed as a palliative neoadjuvant modality. We evaluated whether combination PDT chemotherapy is effective alone.In total, 161 patients diagnosed between February 1999 September 2009 were evaluated. Sixteen treated (group A), 58 B).The median survival was 538 days (95% confidence interval [CI], 475.3 to...
Chronic obstructive pulmonary disease (COPD) is an ambulatory care-sensitive condition, and the rate of hospital admissions for COPD indicator quality outpatient care. We sought to determine long-term trends in Canada.Using a comprehensive national database Canada, we identified those with main discharge diagnosis patients aged 40 years older between 2002 2017. calculated sex-specific, age-standardized annual rates separately younger (40-64 yr) adults (≥ 65 yr). used spline regression...
Objectives: This study aimed to evaluate the adequacy of pancreatic core biopsy in histological diagnosis autoimmune chronic pancreatitis (AIP). Methods: Histopathologic as well immunohistochemical staining using anti-IgG4 antibody was done with tissue specimens 26 AIP patients (19 transabdominal ultrasound (US)-guided biopsies, 3 intraoperative wedge and 4 surgical resections). Eight alcoholic 10 cancer served controls. Results: Lymphoplasmacytic sclerosing (LPSP) histology observed 26%...
To evaluate the effect of photodynamic therapy (PDT) on metal stent patency in patients with unresectable hilar cholangiocarcinoma (CC).This was a retrospective analysis CC referred to our institution from December, 1999 January, 2011. Out 232 patients, thirty-three were treated. Eighteen PDT group treated uncovered stents after one session PDT. Fifteen control alone. Porfimer sodium (2 mg/kg) administered intravenously patients. Forty-eight hours later, using diffusing fiber that advanced...
Background: Patients with acute cholecystitis (AC) often receive antibiotics to reduce the risk of infectious complications after cholecystectomy. This study investigated clinical significance antibiotic use in patients mild-to-moderate AC who required emergency laparoscopic Methods: multicenter, double-blind, randomized controlled trial was conducted at four centers between February 2023 and January 2024. eligible for cholecystectomy were randomly assigned or placebo group. The group...
The most common form in bile duct cancers is a highly desmoplastic cancer with growth pattern characterized by periductal extension and infiltration. prognosis of cancers, especially hilar cholangiocarcinoma, limited tumor spread along the biliary tree leading to refractory obstructive cholestasis, cholangitis, liver failure. Although endoprosthesis improves occlusion rates reduces number therapeutic interventions, median survival time not ameliorated. Photodynamic therapy (PDT) local...
Peripancreatic tuberculous lymphadenopathy is very rare and can be misdiagnosed with pancreatic or peripancreatic malignancies. The clinical characteristics treatment outcome have not been well known. Herein, we investigated the accuracy of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA), features, outcomes.We retrospectively analyzed 42 patients diagnosed tuberculosis between December 2004 January 2011 at tertiary care hospital in Korea.Median age was 36 years (interquartile...
Pre-existing diabetes mellitus (DM) has been identified as an adverse prognostic variable associated with increased mortality in various cancers. Although DM and hyperglycemia are considered risk factors for pancreatic cancer (PC), antidiabetic treatments patients advanced PC have overlooked. This study aimed to evaluate the impact of hemoglobin A1c (HbA1c) levels on survival.We retrospectively reviewed medical records first-diagnosed who were admitted Konkuk University Medical Center from...
Background/Aims Intrahepatic cholangiocarcinoma (ICC) is the second-most common primary liver malignancy, arising from peripheral intrahepatic bile duct epithelium. Hepatitis B virus (HBV) or hepatitis C (HCV) may be involved in development of ICC. We explored prognostic value infection, as well other factors affecting survival patients with Methods A retrospective chart review was performed for diagnosed ICC between August 2005 and December 2018 at Konkuk University Medical Center....
We investigated the impact of direct peroral cholangioscopy (POC)-based holmium laser lithotripsy using an ultrathin endoscope with irrigation via a 2-mm-diameter working channel to remove difficult common bile duct (CBD) stones without separate biliary catheter.Few clinical studies have reported successful removal CBD by POC-based upper endoscope. Previous used catheter ensure continuous irrigation.Ten patients (6 males; mean age 63.3 years) who were not amenable conventional endoscopic...
This study aimed to compare the clinical outcomes of patients with advanced hilar cholangiocarcinoma (CC) who underwent photodynamic therapy (PDT) either percutaneous transhepatic cholangioscopy (PTCS) or endoscopic retrograde cholangiopancreatography (ERCP).PDT has been proposed as a promising for treatment unresectable CC that is resistant conventional standard treatment. However, few studies have compared delivery methods PDT in patients.Thirty-seven adult were included this study....
The Risk of Colorectal Neoplasia in Patients with Gallbladder DiseasesCholecystectomy is associated an increased risk colorectal cancer, but little known about the relationship between gallbladder disease and adenoma.Gallbladder polyps neoplasia (CRN) share several factors such as obesity, diabetes metabolic syndrome, which might account for their association.In this study, we investigated whether asymptomatic patients are at CRN identified to association.The study population consisted 4,626...
Background and objectives: Acute cholangitis can be life-threatening if not recognized early. We investigated the predictive value of neutrophil-lymphocyte ratio (NLR) in acute cholangitis. Materials Methods: retrospectively evaluated 206 patients with who underwent biliary drainage. The severity was graded according to Tokyo 2018 guideline. Patients were dichotomized (mild/moderate vs. severe), presence shock requiring a vasopressor/inotrope, blood culture positivity. baseline NLR, white...
