BACKGROUND Several controversies exist regarding the superiority of double-bundle (DB) posterior cruciate ligament (PCL) reconstruction versus single-bundle (SB) reconstruction, although DB reconstruction has been shown to restore the intact knee kinematics more closely than SB reconstruction. HYPOTHESIS Double-bundle PCL reconstruction will present(More)
Foam cell formation from monocyte-derived macrophages is a hallmark of atherosclerotic lesions. Aspects of this process can be recapitulated in vitro by exposing M-CSF-induced or platelet factor 4 (CXCL4)-induced macrophages to oxidized (ox) or minimally modified (mm) low density lipoprotein (LDL). We measured gene expression in peripheral blood mononuclear(More)
BACKGROUND Although the sixth edition of the American Joint Committee on Cancer (AJCC) staging system for extrahepatic bile duct carcinoma was updated, the system has a problem on T classification due to its ambiguous definition of T1 as "tumor confined to bile duct histologically" and T2 as "tumor invading beyond the bile duct." METHODS The authors(More)
BACKGROUND AND AIM We analyzed the characteristics of gastrointestinal neuroendocrine tumors and examined the outcomes and safety of modalities in rectal neuroendocrine tumors. METHODS Between 2007 and 2011, a total of 91 patients with gastrointestinal neuroendocrine tumors were retrospectively reviewed in terms of the characteristics of tumors. RESULTS(More)
Recent research reveal that the diagnosis of gastric extraluminal compressions mimicking subepithelial tumor is increasing in numbers as esophagogastroduodenoscopy becomes widespread. Endoscopic ultrasonography is a very useful tool for differentiating extraluminal compressions from subepithelial tumors. Gastric extraluminal compressions are due to(More)
BACKGROUND/AIMS Subepithelial tumors are occasionally found during upper gastrointestinal endoscopy. The purpose of this study was to evaluate endoscopic characteristics of mesenchymal tumors originating from muscularis mucosa or muscularis propria. METHODS A total of 307 mesenchymal tumors of the upper gastrointestinal tract were diagnosed between March(More)
Although the relationship between malignancy risk with systemic sclerosis (SSc) has been inconclusive, there are some previous studies for a positive correlation. Most patients with SSc have some degree of lung parenchymal involvement in the form of interstitial thickening and fibrosis. Interstitial lung disease is the most common pulmonary manifestation of(More)
BACKGROUND/AIMS Ciprofloxacin is considered to be a safe and effective treatment for acute infectious colitis. However, this drug may cause drug-induced pancreatitis, albeit rarely. METHODS From March 2007 to February 2012, we studied 227 patients who were hospitalized for infectious colitis at St. Mary's Hospital. All of the patients received(More)
The Sengstaken-Blakemore tube (SB tube) is used to control esophageal or gastric variceal bleeding in emergencies, and various complications have been reported following its use. Tracheoesophageal fistula (TEF) is an extremely rare complication after SB tube insertion. We herein present a case of an 80-year-old female patient who experienced TEF after(More)
