Dermatomyositis (DM) is a kind of idiopathic inflammatory myopathy characterized by chronic proximal skeletal muscle weakness and unique skin lesions. However, DM with exfoliation of esophageal mucosa is rare. A 36-year-old male patient complained of muscular soreness of extremities, dysphagia, and pharyngalgia was diagnosed with DM with exfoliation of esophageal mucosa. After treatment with glucocorticoid, immunosuppressant, acupuncture, and endoscopic submucosal dissection (ESD), the above symptoms were disappeared. During the 3-year follow-up period, the results of routine physical examination, laboratory examination, gastroscopy, and imaging examination were normal. High-dose of corticosteroid is needed in the initial treatment, but it must be reduced regularly to avoid adverse reactions. Acupuncture and ESD are also effective as adjuvant therapy.

Multiple primary cancers, i.e., the occurrence of multiple malignant neoplasms in a single patient, were first reported by Billorth in 1889. The incidence is low but increasing gradually due to developments in cancer diagnosis, early detection, and prolongation of life. In Korea, double primary cancers are occasionally reported. However, the simultaneous presence of four primary cancers in a single patient is rare. Recently, we experienced the case of a 68-year-old male diagnosed with quadruple primary cancers involving the esophagus, tonsils, liver and buccal mucosa. Here, we report this very rare case of four metachronous primary neoplasms and provide a brief review of the related literature.

Hemangioma of the esophagus is a rare form of benign esophageal tumor. It usually presents as a single lesion located in the lower third of the esophagus and is mostly asymptomatic. However, it may occasionally cause hematemesis and/or obstruction. Surgical resection is the conventional treatment modality for managing esophageal hemangioma, but less invasive approaches such as endoscopic therapy are recently becoming more widely employed. Herein, we report a case of a 54-year-old man who presented with an esophageal hemangioma that was successfully treated by endoscopic mucosal resection without any complications.

BACKGROUND/AIMS: Endoscopic resection (ER) of superficial esophageal neoplasm (SEN) is a technically difficult procedure. We investigated the clinical outcomes of ER for SEN to determine its feasibility and effectiveness. METHODS: Subjects who underwent ER for SEN at Asan Medical Center between December 1996 and December 2010 were eligible. The clinical features of patients and tumors, histopathological characteristics, adverse events, ER results and survival were investigated. RESULTS: A total of 129 patients underwent ER for 147 SENs. En bloc resection (EnR) was performed in 118 lesions (80.3%). Complete resection (CR) was accomplished in 128 lesions (86.5%), and curative resection (CuR) was performed in 118 lesions (79.7%). The EnR, CR, and CuR rates were significantly greater in the endoscopic submucosal dissection group when compared to those in the endoscopic resection group. Adverse events occurred in 22 patients (17.1%), including bleeding (n=2, 1.6%), perforation (n=12, 9.3%), and stricture (n=8, 6.2%). Local tumor recurrence occurred in 2.0% of patients during a median follow-up of 34.8 months. The 5-year overall and disease-specific survival rates were 94.0% and 97.5%, respectively. CONCLUSIONS: ER is a feasible and effective method for the treatment of SEN as indicated by favorable clinical outcomes.

BACKGROUNDEndoscopic submucosal dissection of the esophagogastric junction is the most difficult gastric and esophageal dissection procedure. No reports of endoscopic submucosal dissection for Siewert type II carcinoma of the esophagogastric junction have compared the outcomes of endoscopic submucosal dissection for all three Siewert types of adenocarcinoma. This study aimed to evaluate the efficacy and safety of endoscopic submucosal dissection for intraepithelial neoplasia of the esophagogastric junction.

METHODSFrom October 2008 to June 2013, 73 patients underwent endoscopic submucosal dissection for intraepithelial neoplasia of the esophagogastric junction. The patients were prospectively evaluated regarding the executability of the technique, short-term results of the procedure, en bloc resection rate, curative resection rate, complications and additional treatment after endoscopic submucosal dissection, and follow-up outcomes.

RESULTSSixty-eight of the 73 patients (93.2%) underwent en bloc resection; the mean maximum specimen diameter was 33.7 mm. Fifty-seven of 61 patients (93.4%) who underwent curative resection were successfully followed-up for 1.0 to 56.0 months (average, 24.1 months). Local recurrence developed in one patient with high-grade intraepithelial neoplasm. Twelve patients underwent noncurative resection, including lateral resection margin residues in three, vertical resection margin residues in one, signet ring cell carcinoma or undifferentiated adenocarcinoma in four, lymphatic or vessel invasion in one, vertical residual margin residues combined with signet ring cell carcinoma in one, and undifferentiated adenocarcinoma with lymphatic or vessel invasion in two. In the noncurative resection group, one patient was lost to follow-up, seven underwent additional surgery, and the remaining four were periodically followed up; none had local recurrence or distant metastases. The only complication was delayed bleeding in three patients, which was successfully controlled by conservative treatment or endoscopic therapy.

CONCLUSIONSEndoscopic submucosal dissection is safe and effective for intraepithelial neoplasia of the esophagogastric junction. R0 en bloc resection is possible and can avoid the risk of local recurrence.

BACKGROUND/AIMS: Submucosal tumors of the esophagus are rare lesions among all esophageal neoplasms. The purpose of this study was to evaluate the clinicopathologic features of esophageal submucosal tumors treated by surgical approach. METHODS: We analyzed the clinicopathologic and endoscopic ultrasonographic features of 18 esophageal submucosal tumors which were treated by surgical approach at Boramae Medical Center and Seoul National University Bundang Hospital from January 2005 to June 2012. RESULTS: The mean age was 48.9 years old and male to female ratio was 2.6:1. Asymptomatic patients were most common (77.8%). In endoscopic ultrasonographic finding, the majority tumor arouse in the middle (55.6%) and lower (44.4%) esophagus, and appeared as hypoechoic lesion (72.2%) in the 4th layer (83.3%). The most common indication for surgical approach was unclear biological behavior of the tumor. Minimally-invasive technique using thoracoscopy was applied for the enucleation (83.3%). The mean diameter of the tumor was 5.4 cm, and the final diagnosis was leiomyoma (89.9%) and gastrointestinal stromal tumor (11.1%). CONCLUSIONS: Leiomyoma was the most common submucosal tumor in esophagus. However, endoscopic ultrasonography was not able to differentiate between leiomyoma and gastrointesinal stromal tumor. For more accurate diagnosis and treatment, minimally-invasive approaches may be suitable for the surgical enucleation of indicated esophageal submucosal tumor.

BACKGROUND/AIMS: The endoscopic findings and clinical relevance of portal hypertensive colopathy are not well described in Korea. We aimed to do a retrospective study of mucosal changes in the colon of patients with liver cirrhosis and to find their association with clinical characteristics. METHODS: We reviewed the clinical data and endoscopic findings of 48 patients with liver cirrhosis and 48 patients, matched for age and sex, with irritable bowel disease (IBS) who underwent colonoscopy over a 5 year span. RESULTS: Patients with liver cirrhosis were more likely to have colitis-like lesions and vascular abnormalities than IBS patients. Low platelet count (p=0.005) and severe esophageal varices (p=0.011) were associated with portal hypertensive colopathy, whereas the etiologies and severity of cirrhosis were not associated with these findings. CONCLUSIONS: Portal hypertensive colopathy can be defined with colitis-like lesions or vascular lesions. These lesions are more frequently present in patients with more severe esophageal varices and thrombocytopenia.

Intestinal mucosa plays important roles in digestion, absorption and substance exchange between organism and external environment. Meanwhile, it is the largest immune organ and mucosal barrier, including mechanical, biological and immune barrier. A variety of diseases, especially postoperative complications, are associated with the damage of mucosal barrier. Esophageal cancer surgery is complex and many perioperative factors, especially hypoperfusion and fasting, may affect the integrity of intestinal barrier. Understanding of the mechanism of intestinal barrier (mechanical, biological and immune barrier), the physiological function of probiotics, and the benefit of early enteral nutrition to intestinal barrier are important components to achieve fast recovery after surgery for esophageal cancer.

Portal hypertensive gastropathy (PHG) is a term used to define the endoscopic findings of gastric mucosa with a characteristic mosaic-like pattern with or without red spots, and a common finding in patients with portal hypertension. These endoscopic findings correspond to dilated mucosal capillaries without inflammation. The pathogenesis of PHG in not well known, but portal hypertension and some humoral factors seem to be crucial factors for its development. Pharmacological (e.g. propranolol), or interventional radiological (such as transjugular intrahepatic portosystemic shunt) procedures may be useful in preventing re-bleeding from PHG. The classic features of gastric antral vascular ectasia (GAVE) syndrome include red, often haemorrhagic lesions predominantly located in the gastric antrum which can result in significant blood loss. Although the pathogenesis of GAVE is not clearly defined, it seems to be a separate disease entity from PHG, because GAVE generally does not respond to a reduction of portal pressures. Endoscopic ablation (such as argon plasma coagulation) is the first-line treatment of choice. This review will focus on the incidence, clinical importance, etiology, pathophysiology, and treatment of PHG and GAVE syndrome in the setting of portal hypertension.

OBJECTIVEThe aim of this study was to observe the association between the occurrence of esophageal cancer lesions and esophageal mucosa fold (white ridges), and further identify where is the initial origin of esophageal cancer lesions in the esophagus mucosa.

METHODSThis was a cohort study which recruited 551 subjects underwent endoscopic examination in a high risk area of esophageal cancer in Linxian, Henan Province in 1987. 339 subjects with esophageal white ridges, and with red area or erosion lesion at the surface of the white ridges, was studied as exposure group. Other 212 subjects whose esophagus had no white ridges and pathological diagnosis was negative, was studied as control group. The endpoint was occurrence of pathologically confirmed esophageal cancer. After a 15-year follow-up, the results were compared between two groups.

RESULTSAmong the 551 subjects, there were 339 cases with esophageal mucosal white ridges in the exposure group. During the period of 15 year follow-up, the incidence of esophageal cancer was 11.8% (9/76) in 76 case with simple mucosal white ridges, 33.5% (88/263) in 263 subjects with white ridges and red area, or erosions on the surface of white ridge. While only 8.0% of subjects (17/212) developed esophageal cancer after the 15-year follow up in the control group. There was a significant difference between the two groups (P < 0.001).

CONCLUSIONEsophageal mucosal white ridge, especially white ridge with red area or erosions is closely associated with subsequent esophageal cancer occurrence in the esophageal cancer high risk area in China. It is suggested that esophageal mucosa with white ridge may be the initial origin of esophageal cancer. Further investigations focused on this spot are required.
