Nowadays, gastropathy is a common disease. As endoscopic equipment are developed and used widely, it is possible to provide a large number of endoscopy images. Computer-aided Diagnosis (CADx) systems aim at helping physicians to identify possibly malignant abnormalities more accurately. In this paper, we present a CADx system to detect and classify the abnormalities of gastric lesions which include bleeding, ulcer, neuroendocrine tumor and cancer. We used an Inception module based deep learning model. And we used data augmentation for learning. Our preliminary results demonstrated promising potential for automatically labeled region of interest for endoscopy doctors to focus on abnormal lesions for subsequent targeted biopsy, with Az values of Receiver Operating Characteristic(ROC) curve was 0.83. The proposed CADx system showed reliable performance.

The microwave tissue coagulator was originally used for hemostasis in the hepatic surgery, which is effectively applied in the endoscopic surgery such as the hemostasis of gastric ulcer or tumor bleeding, stenosis relieving of esophageal or rectal stenosis and tumor reduction in inoperable early cancer cases. We experienced the good result of the microwave tissue coagulation therapy in the patient with the restenosis of esophagogastrostomy. The patient was 67 year-old female, who was admitted due to the lye stricture of esophagus for 40 years. We made the lower esophagectomy and the esophagogastrostomy with the upper intact esophagus in the right thorax. But the restenosis occurred at the esophagogastrostomy site because of the polypoid mucosal protrusion at one month after operation. We applied the microwave tissue coagulator 3 times with 6 day interval under esophagoscopy and the good symptomatic and endoscopic relief was alleviated. We think that the microwave tissue coagulation is a very convenient and advisable method in the case of restenosis after esophageal surgery.

The microwave tissue coagulation therapy was originally used for hemostasis in the hepatic surgery, which is effectively applied in the endoscopic surgery such as the hemostasis of gastric ulcer or tumor bleeding, stenosis relieving of esophageal or rectal stenosis and tumor reduction in inoperable early cancer cases.We experienced one case of the restenosis after the tracheal reconstruction. The patient, who was 42 year-old male, had severe dyspnea due to the tracheal stenosis for 4 years. The resection of tracheal stenosis and tracheal reconstruction was done. But the restenosis occurred at the tracheal anastomosis site because of the protrusive granulation at one month after operation. The patient was successfully treated by the microwave tissue coagulation therapy.

Heterotopic pancreas (HP) is defined as pancreatic tissue lacking anatomic and vascular continuity with the main body of the pancreas. Most are asymptomatic, but can cause ulcer, bleeding, intussusception, and mechanical obstruction. Herein, we presented one case of HP presented as duodenal tumor causing duodenal obstruction. A 7-year-old girl visited the emergency room for abdominal pain with vomiting for 24 hours. Computed tomography and upper gastrointestinal series revealed a polypoid mass with short stalk in the 2nd portion of duodenum. We attempted an endoscopic removal. However, the lumen was nearly obstructed by the mass and the stalk was too broad and hard to excise. The mass was surgically removed via duodenotomy. It was confirmed as a HP with ductal and acini components (type 2 by Heinrich classification). Postoperatively, the patient has been well without any complication and recurrence.

Nonsteriodal antiinflammatory drugs(NSAIDs) are widely used to treat pain, fever, and inflammatory conditions including osteoarthritis. But chronic patients suffer from gastrointestinal disturbances such as discomfort, nausea, peptic ulcer and severe bleeding because NSAIDs inhibit not only COX-2 associated with anti-inflammatory activity, but also COX-l accompanied with side effects in the stomach and kidney. Therefore, in this study, we designed a new 2-thiohydantoin derivatives as selective COX-2 inhibitors is that the 5-membered heterocycle ring is substituted with two aryl groups. (omitted)

Nonsteroidal antiinflammatory drugs(NSAIDs) are widely used to treat pain. fever and inflammatory condition. But chronic-disease patients suffer from gastro-intestinal disturbances such as discomfort. nausea. peptic ulcer and severe bleeding because NSAIDs inhibit not only COX-2 associated with anti-inflammatory activity but also COX-1 associated with adverse gastro-intestinal effects. On the basis of this fact. specific COX-2 inhibitors such as celecoxib and rofecoxib are introduced in the drug market. (omitted)

Purpose: We are going to establish the efficacy of endoscopic examinations in diagnosing and treating upper GI bleeding in full term neonates. Methods: We retrospectively reviewed newborns who underwent endoscopic examination because of hematemesis from July 1998 to April 2001. Results: Gestational ages were between 38 and 41weeks, and birth weights were between 2,730 and 3,400 gm. Total of 9 patients were reviewed. Endoscopic examination revealed gastric ulcer in 6 cases, multiple erosions in 2 cases and negative finding in 1 case. All 6 gastric ulcers were multiple and among them 2 patients endoscopic hemostatic therapy. No complication due to the procedure was noticed. Five patients recieved transfusions. All 9 cases were cured through conservative and endoscopic therapy without recurrence. Conclusion: The common cause of upper GI hemorrhage in newborns with no preceding disease turns out to be multiple gastric ulcers and the prognosis is good. The endoscopic approach is useful in diagnosing and treating upper GI bleeding in newborns.

Hyperplastic gastric polyps (HPPs) are the most common type of gastric polyps. They are assumed to be caused by chronic inflammation and regenerative proliferation, although this has not been clearly investigated yet. Many studies suggested the development of fundic gland polyps and carcinoid during long-term proton pump inhibitor (PPI) therapy, but the relationship between PPIs and HPPs is still unclear. We encountered a patient who showed aggravation of HPPs after long-term use of PPIs. A 58-year-old male patient with liver cirrhosis visited our hospital because of hematemesis. We started PPI medication after confirming esophageal variceal bleeding and duodenal ulcer with blood clot in its base via emergency endoscopy. He took PPIs for three years because of an intractable duodenal ulcer. There was a marked increase in the size of the pre-existing polyps and in the development of new polyps. We presumed that the PPIs caused the aggravation of the HPPs, so we stopped their administration. After five months, the HPPs shrank and the polyps were partially degraded. More prospective studies are needed to investigate the relationship between HPPs and PPIs.

The purposes of this research were to identify nursing interventions performed by Korean nurses and to compare the interventions performed by nurses working in the oriental medicine hospitals and with those performed by nurses working in the general hospitals. The samples consisted of 144 Korean nurses working in three hospitals, 70 nurses working in the oriental medicine hospitals and 74 nurses working in the general hospitals. The Nursing Interventions Classification (NIC) Use Questionnaire developed by the Iowa Intervention Project team was translated to Korean and verified using the method of back-translation. The questionnaire consists of 433 intervention labels and definition. Thirteen interventions were used at least daily by nurses working in the oriental medicine hospitals, while twenty-one interventions were used at least daily by nurses working in the general hospitals. The most frequently used interventions by nurses working in the oriental medicine hospitals were Documentation, Shift Report Vital Signs Monitoring, Pressure Ulcer Prevention, Positioning, Fall Prevention, Exercise Promotion, Intravenous (IV) Therapy, Pressure Ulcer care, and Bed Rest Care in that crder. For nurses working in the general hospitals the most frequent intervention was Analgesic Administration, followed by the interventions of Medication Administration : Parenteral and Intravenous Therapy (IV) Therapy, Documentation, Intravenous(IV) Insertion, Shift Report, Fall Prevention, Vital Signs Monitoring, Medication Adnninistraction : and, Fluid Monitoring, and Medication Maragement in that order. The interventions performed least often by nurses working in the oriental medicine hospitals were Hemodialysis Therapy and Bleeding Reduction : Antepartum Uterus, while the interventions performed least often by nurses working in the general hospitals were Rape Trauma Treatment and Contact Lens Care. The nurses working in the oriental medicine hospitals performed the interventions in the Physiological : Complex domain significantly more often than the nurses working in the general hospitals, while the nurses working in the general hospitals performed the intervention in the Behavior domain significantly more often than the nurses working in the oriental medicine hospitals. This study suggests that further study will be needed to developed and validate more interventions sensitive to Korean culture.

Gastric tuberculosis accounts for approximately 2% of all cases of gastrointestinal tuberculosis. Diagnosis of gastric tuberculosis is challenging because it can present with various clinical, endoscopic, and radiologic features. Tuberculosis manifesting as a gastric subepithelial tumor is exceedingly rare; only several dozen cases have been reported. A 30-year-old male visited emergency room of our hospital with hematemesis and melena. Abdominal CT revealed a 2.5 cm mass in the gastric antrum, and endoscopy revealed a subepithelial mass with a visible vessel at its center on gastric antrum. Primary gastric tuberculosis was diagnosed by surgical wedge resection. We report a rare case of gastric tuberculosis mimicking a subepithelial tumor with acute gastric ulcer bleeding.
