Purpose: The aim of this study is to evaluate the feasibility and safety of cardia preserving proximal gastrectomy, in early gastric cancer of the upper third. Materials and Methods: A total of 10 patients were diagnosed with early gastric cancer of the upper third through endoscopic biopsy. The operation time, length of resection free margin, number of resected lymph nodes and postoperative complications, gastrointestinal symptoms, nutritional status, anastomotic stricture, and recurrence were examined. Results: There were 5 males and 5 females. The mean age was $56.5{\pm}0.5$ years. The mean operation time was $188.5{\pm}0.5$ minutes (laparoscopic operation was 270 minutes). Nine patients were T1 stage (T2 : 1), and N stage was all N0. The mean number of resected lymph nodes was $25.2{\pm}0.5$. The length of proximal resection free margin was $3.1{\pm}0.1$ cm and distal was $3.7{\pm}0.1$ cm. Early complications were surgical site infection (1), bleeding (1), and gastro-esophageal reflux disease (1) (this symptom was improved with medication). Late complications were dyspepsia (3) (this symptom was improved without any treatment), and others were nonspecific results of endoscopy or symptom. Conclusions: Cardia preserving proximal gastrectomy was feasible for early gastric cancer of the upper third. Further evaluation and prospective research will be required.

Dysphagia may result from dysfunction of any of the components involved in the complex neuromuscular interaction of swallowing. Hyperfunction of any of the muscles involved in swallowing is a frequent cause of dysphagia. The cricopharyngeus muscle (CPM) is a key component of the upper esophageal sphincter. Cricopharyngeus muscle dysfunction (CPD) refers to the muscle's failure to appropriately and completely relax or expand during deglutition. A variety of disease processes may cause CPD and accurate diagnosis is paramount for appropriate treatment. In appropriately selected patients, intervention at the CPM may yield significant improvement in dysphagia. Interventions include nonsurgical, pharyngoesophageal segment dilatation, botulinum toxin (BoNT) injection, and criccopharyngeal myotomy. Injections of BoNT in patients with CPD have been reported to result in marked relief of dysphagia. Different techniques for instilling BoNT into the CPM have been described. Awake, in-office CPM BoNT injection with electromyography and/or fluoroscopic or ultrasound guidance is performed transcervically or via flexible endoscopy. Operative CPM BoNT injection involves rigid laryngoscopy and esophagoscopy with direct visualization of the CPM. BoNT should be prepared in low-volume, high-concentration dilutions to minimize the potential for undesired diffusion of the toxin. The effects of BoNT occur within weeks of injection and typically last up to 5 or 6 months.

Acquired bronchoesophageal fistula rare. Conservative treatment such as endoscopy is widely used. The recurrence rate after endoscopic treatment, however, is not well known. We report here on a case of a 54-year-old female who presented with recurrent bronchoesophageal fistula after endoscopic treatment that filled the fistula tract with $Histoacryl^{(R)}$.

Achalasia is very uncommon in children, and cases accompanied with alacrima and adrenal insufficiency is even more uncommon. When these three disorders are seen altogether, it is called triple A syndrome. It is inherited in an autosomal recessive manner and has potentially life-threatening sequelae. So, pediatricians should always consider the possibility of triple A syndrome when seeing children with achalasia. Neurological abnormalities such as autonomic neuropathy, peripheral neuropathy, sensory impairment and mental retardation occasionally accompany. We report a 2-year-old girl who presented with repeated vomiting, short stature and alacrima. Diagnosis of achalasia was made after perfoming esophagogram and endoscopy and was confirmed with esophageal manometry. After pneumatic dilatation, she became asymptomatic.

A previously healthy 3-year-old girl was admitted to the Department of Pediatrics in Severance Hospital with sudden symptoms of melena. The vital signs were stable, and splenomegaly was found in a physical examination. The patient had moderate thrombocytopenia. There was no evidence of autoimmune disease. A upper gastrointestinal endoscopy and esophagogram showed a varix on the lower esophagus. Coarse liver parenchymal echoes and increased periportal echogenicity were seen on a Doppler sonogram. The velocity of the portal vein mildly increased. Magnetic-resonance-cholangiopancreatogram (MRCP) demonstrated normal portal structures. A sono-guided liver biopsy was performed, but the pathological findings were unremarkable. Based on these findings, we diagnosed the patient with idiopathic portal hypertension. The patient was discharged and was treated with oral beta blocker. We report a case of idiopathic portal hypertension with a brief review of the literature.

Cyclic vomiting syndrome (CVS) is a functional disorder characterized by stereotypical episodes of intense vomiting separated by weeks to months. Although it can occur at any age, the most common age at presentation is 3-7 years. There is no gender predominance. The precise pathophysiology of CVS is not known but a strong association with migraine headaches, in the patient as well as the mother indicates that it may represent a mitochondriopathy. Studies have also suggested the role of an underlying autonomic neuropathy involving the sympathetic nervous system in its pathogenesis. CVS has known triggers in many individuals and avoiding these triggers can help prevent the onset of the episodes. It typically presents in four phases: a prodrome, vomiting phase, recovery phase and an asymptomatic phase until the next episode. Complications such as dehydration and hematemesis from Mallory Wise tear of the esophageal mucosa may occur in more severe cases. Blood and urine tests and abdominal imaging may be indicated depending upon the severity of symptoms. Brain magnetic resonance imaging and upper gastrointestinal endoscopy may also be indicated in certain circumstances. Management of an episode after it has started ('abortive treatment') includes keeping the patient in a dark and quiet room, intravenous hydration, ondansetron, sumatriptan, clonidine, and benzodiazepines. Prophylactic treatment includes cyproheptadine, propranolol and amitriptyline. No mortality has been reported as a direct result of CVS and many children outgrow it over time. A subset may develop other functional disorders like irritable bowel syndrome and migraine headaches.

The congenital tracheoesophageal fistula without atresia of the esophagus is considered a rare variant, and the literature concerned to the tracheoesophageal fistula without atresia, is little in adult especially. The 22-year-old male was admitted to Yeungnam University Hospital with his chief complaints of weight loss (6kg/6 months), abdominal discomfort, and intermittent coughing. The diagnosis was made by the endoscopy and esophagography. The fistula was 1.5cm in diameter, 0.5cm in length. The level was around second thoracic vertebra. The operation was performed transpleurally through the right third intercostal space and the fistula was secured with interrupted silk suture after division. The fibrotic adhesion was seen around the tracheoesophageal fistula. The postoperative course was uneventful, and postoperative esophagogram revealed ho extraluminal leakage. Herewith we report this unusual case of isolated tracheo-esophageal fistula with review of literatures.

Hemangioma in the esophagus is an uncommon tumor. There have only been about 30 cases reported in the world literatures. It occurs predominantly in men and although majority are asymptomatic, may cause bleeding and dysphagia. Hemangioma in the esophagus was diagnosed with a barium swallowed esophagography and endoscopy. The main treatment modes recommended are surgery and endoscopic resection. We experienced one case of cav ernous hemangioma occurring at the distal esophagus. The patient was a forty-six year old male with dysphagia and indigestion. Barium esophagogram showed a filling defect at the distal portion. Esophagoscopy showed a bluish polypoid mass. Surgical resection was per formed and the pathologic diagnosis was confirmed as cavernous hemangioma. Postoperative course was uneventful and the patient had been followed up without any problems.

Vagal damage and subsequent pyloric denervation inevitably occur during esophagectomy, potentially leading to delayed gastric emptying (DGE). The choice of an optimal pyloric procedure to overcome DGE is important, as such procedures can lead to prolonged surgery, shortening of the conduit, disruption of the blood supply, and gastric dumping/bile reflux. This study investigated various pyloric methods and analyzed comparative studies in order to determine the optimal pyloric procedure. Surgical procedures for the pylorus include pyloromyotomy, pyloroplasty, or digital fracture. Botulinum toxin injection, endoscopic balloon dilatation, and erythromycin are non-surgical procedures. The scope, technique, and effects of these procedures are changing due to advances in minimally invasive surgery and postoperative interventions. Some comparative studies have shown that pyloric procedures are helpful for DGE, while others have argued that it is difficult to reach an objective conclusion because of the variety of definitions of DGE and evaluation methods. In conclusion, recent advances in interventional technology and minimally invasive surgery have led to questions regarding the practice of pyloric procedures. However, many clinicians still perform them and they are at least somewhat effective. To provide guidance on the optimal pyloric procedure, DGE should first be defined clearly, and a large-scale study with an objective evaluation method will then be required.

We report a bronchoesophageal fistula that treat with bronchial stent insertion and histoacryl injection. A 52-year-old man with esophagel cancer was transferred for dysphagia management. At the CT scan that underwent on admission, esophageal cancer with multiple lymph node metastasis was observed. At the gastroduodenoscopy and contrast study, bronchoesophageal fistula was observed. Recurrent stent insertion treatment was failed, and then, By the broncoscopy, covered stent was inserted to right bronchus, and By the endoscopy, fibrin glue and histoacryl was injected in the fistula opening. At the contrast study, contrast leakage was not observed, and the patient was discharged. But, at the 14 days after discharge, the patient was admitted to the emerency room because of cough symptom whenever he eat food. The patient was diagnosed with aspiration pneumonia, we were determined that it is unable to oral intake. The patient received a jejunostomy and antibiotic treatment for aspiration pneumonia. He was discharged after symptomatic improvement.
