BACKGROUND EMR has been accepted as a treatment modality for selected cases of early gastric cancer (EGC) in Japan. However, long-term outcomes after EMR for EGC have not been fully documented. OBJECTIVES We reviewed the experiences of EMR for EGC in Korea, with emphasis on the long-term outcome. DESIGN Multicenter, retrospective study. METHODS Data(More)
We report a rare case of a gastric plasmacytoma treated with endoscopic resection and oral thalidomide therapy. A 70-year-old man was admitted to our hospital with indigestion. He had no specific medical history and unremarkable laboratory results. Gastroendoscopic findings revealed a focal, erythematous, flat elevated lesion in the anterior wall of the(More)
Primary signet ring cell carcinoma (SRC) of colon at early stage is quite rare. Only 26 cases were reported until now. We report an early stage of primary SRC which was misdiagnosed as a juvenile polyp and treated with polypectomy followed by surgical resection. A 21-year-old male was administered for hematochezia. Abdominopelvic enhanced computed(More)
A primary leiomyosarcoma of the kidney is a rare, but highly aggressive, neoplasm, accounting for only 0.1% of all invasive renal tumors. Local or systemic recurrence is common, but a leiomyosarcoma is difficult to diagnose preoperatively. We recently encountered an interesting case of an unusual recurrence of a renal leiomyosarcoma. A 57-year-old woman(More)
OBJECTIVE To determine if the level of serum C-reactive protein (CRP) can be used to differentiate between inflammatory diarrhea and non-inflammatory diarrhea in patients with acute infectious diarrhea or acute gastrointestinal infection. METHODS This was a retrospective study based on medical records from a single military hospital located in Daejeon,(More)
BACKGROUND/AIMS Signal transducers and activators of transcription (STATs) are a family of transcription factors that are activated in response to cytokines and growth factors. STAT3 activation has been implicated in modulating the activity of downstream mediators, such as Bcl-xL and matrix metalloproteinase-2 (MMP-2). The aim of this study was to(More)
Gastric yolk sac tumors are extremely rare and their prognosis is poor; most patients have widespread metastases at the time of diagnosis. The treatment of gastric yolk sac tumors consists of aggressive chemotherapy combined with radiotherapy and surgery. Here, we first report a case of gastric yolk sac tumor presenting as an early gastric cancer that was(More)
BACKGROUND/AIMS The purpose of this study was to evaluate clinical outcome of proximal and total gastrectomy regarding reflux esophagitis, nutritional state, and anemia in early gastric cancer. METHODS 94 patients with early gastric cancer were included from January 2001 to January 2007 at Chungnam National University Hospital. Of whom 40 patients (31 men(More)
PURPOSE A colonoscopic polypectomy is an important procedure for preventing colorectal cancer, but it is not free from complications. Delayed hemorrhage after a colonoscopic polypectomy is one infrequent, but serious, complication. The aim of this study was to identify the risk factors for delayed hemorrhage after a colonoscopic polypectomy. METHODS This(More)
BACKGROUND/AIMS Early gastric cancer (EGC) that is undifferentiated or shows submucosal invasion has not been generally accepted as an indication for endoscopic treatment. But recently, experiences with endoscopic submucosal dissection (ESD) for undifferentiated EGC or submucosal invasive (SM) EGC have increased. The aim of this study was to evaluate(More)
