BACKGROUND/AIMS: The Dieulafoy lesion is an important cause of gastrointestinal bleeding. The bleedings from caliber- persistent vessel or abnormally large and tortuous submucosal artery are usually located on proximal stomach. Endoscopic band ligation (EBL) is currently regarded as the treatment of choice of Dieulafoy lesions. This study reports on the clinical features, the efficacy and safety of EBL. METHODS: 10 patients with Dieulafoy-like lesion (median age: 47 yr range: 22~71, M:F 8:2 ) were treated using EBL. EBL was performed as the primary hemostatic tratment as follows in 8 cases of urgency and 2 cases of emergency. RESULTS: The location of all lesions (n=10) were in stomach, 8 in body (4 in posterior wall), 2 in fundus. The bleeding focuses were identified during the first endoscopy. Five lesions were bleeding, 5 had adherent clots or protruding vessels without active bleeding. Hemostasis were achieved with first session of EBL in 9 patients successfully, one case in the fundus was failed due to early band release. CONCLUSION: EBL is a simple, effective, and safe endoscopic method of Dieulafoy-like lesions and, it should be proposed as a primary option.

Gastric antral vascular ectasia (GAVE) is a rare but important cause of chronic gastrointestinal bleeding. Endoscopically, it has characteristic thickened red vascular folds radiating from the pylorus to the antrum. Diagnosis is made primarily by endoscopy. Histologic examination of the endoscopic mucosal biopsies may confirm the endoscopic diagnosis. Many treatment modalities of the gastric antral vascular ectasia exist. One of them, the argon plasma coagulation (APC) is an excellent therapeutic tool. Inactive argon gas is converted to ionized form by means of electrical energy. Ionized argon plasma conducts high frequency electrical energy to tissues and leads coagulation necrosis of tissues. We experienced a case of gastric antral vascular ectasia presenting melena for about one month in a 72-year-old man treated endoscopically in four sessions with argon plasma coagulation.

PURPOSE: The purpose of this study is to investigate the role of fibroblast growth factor receptor 4 (FGFR4) polymorphism in esophageal cancer after chemoradiotherapy (CRT). MATERIALS AND METHODS: Peripheral blood samples from 244 patients treated with CRT for esophageal squamous cell carcinoma were assessed for the role of FGFR4 genotype on treatment response and survival. RESULTS: A total of 94 patients were homozygous for the Gly388 allele, and 110 were heterozygous and 40 homozygous for the Arg388 allele. No significant association was found between the FGFR4 genotype and clinicopathological parameters. However, patients carrying the Gly388 allele showed a better overall response rate than Arg388 carriers (p=0.038). In addition, Gly388 allele patients at an earlier stage showed better overall survival (OS) and progression-free survival than Arg388 carriers. Among these, the Gly388 allele showed significantly improved OS compared to Arg388 carriers in the lymph node (LN) metastasis group (p=0.042) compared to the no LN metastasis group (p=0.125). However, similar survival outcomes were observed for advanced-stage disease regardless of genotype. CONCLUSION: This result suggests that the role of FGFR4 Gly388 in treatment outcomes differs according to esophageal cancer stage. It showed a predictive role in the response of esophageal cancer patients to CRT with a better trend for OS in Gly388 than Arg388 carriers in the early stages. In particular, LN-positive early-stage patients carrying the Gly388 allele showed improved OS compared to those carrying Arg388.

BACKGROUND: Compared with classic achalasia, vigorous achalasia has been defined as achalasia with relatively high esophageal contraction amplitudes, often with minimal esophageal dilation and prominent tertiary contractions on radiographs and the presence of chest pain. The lesser success of pneumatic balloon dilation, also, has been reported for the subset with vigorous achalasia. Nevertheless, some authors have questioned the usefulness of making this distinction. We evaluated the difference of clinical manifestations and response to pneumatic balloon dilation between classic and vigorous achalaisia. METHODS: 28 cases involving patients with achalasia who underwent balloon dilation treatment were available for the review of their clinical findings, radiographic, manometric, esophageal scintigraphic parameters. Patients with vigorous achalasia [n=10] were defined by contraction amplitude >or=37 mmHg on esophageal manometry and patients with classic achalasia [n=18] as contraction amplitude <37 mmHg. RESULTS: Both groups of patients had substantial overlap in clinical findings, radiographic, manometric and esophageal scintigraphic parameters. The success rates of balloon dilation, also, were similar for both groups (classic vs vigorous, 78% vs 70%). CONCLUSION: It is concluded that the distiction of achalasia as classic and vigorous by an amplitude criterion is arbitrary and not useful.

BACKGROUND: Failed or hypotensive peristalsis, two of the diagnostic criteria for NEMD, correlates with impaired anterograde propulsion and retrograde escape of esophageal contents. The aim of this study was to evaluate esophageal acid clearance (EAC) in patients with ineffective esophageal motility (IEM). METHODS: Of 252 patients performing esophageal manometry and ambulatory esophageal pH monitoring, 51 patients with normal motility and acid reflux and 40 patients with IEM and acid reflux were included. RESULTS: The amplitude of peristaltic waves in the proximal and distal esophagus and lower esophageal sphincter pressure was lower significantly in patients with IEM than those with normal motility. Percentage of time of pH<4 in total, upright, and supine period and number of reflux episodes was not different in both. Supine EAC was significantly increased in patients with IEM when compared to those with normal motility. Upright EAC was not different in both. CONCLUSION: We concluded supine EAC is increased in patients with IEM. Since IEM is frequently associated with gastroesophageal reflux disease (GERD), a more intensive therapy must be needed. We propose IEM can be as a specific entity of primary esophageal motility disorder, especially in patients with GERD.
