As gastroduodenoscopy performed more frequently, case reports of human echinostomiasis are increasing in Korea. A Korean woman presented at a local clinic with complaints of abdominal pain and discomfort that had persisted for 2 weeks. Under gastroduodenoscopy, two motile flukes were found attached on the duodenal bulb, and retrieved with endoscopic forceps. She had history of eating raw frog meat. The two flukes were identified as Echinostoma hortense by egg morphology, 27 collar spines with 4 end-group spines, and surface ultrastructural characters. This report may prove frogs to be a source of human echinostome infections.

dopamine이 십이지장구를 포함한 소장의 운동성에 미치는 영향, cholecystokinin이 dopamine의 작용에 미치는 영향 그리고 이들 작용의 신경성 기전을 알아보고자 다음과 같은 실험을 실시하였다. ether로 마취한 토끼 54마리에서 십이지장구, 십이지장, 공장 그리고 회장을 적출하고 절편(길이 1cm)을 만들어 Krebs-Ringr 용액이 채워진 기록 용기에 넣고 자발적인 등장성 수축을 기록하였다. Krebs-Ringr 용액에는 5% $Co_2$를 함유하는 $O_2$를 계속 공급하였으며, 용액의 온도가 $37^{\circ}C$를 유지하도록 하였다. 자발적 수축이 시작하고 20분이 경과한 다음 dopamine($10^{-4}M$), CCK-8($10^{-8}M$), dopamine($10^{^6}M$)등을 투여하면서 수축성을 관찰하여 다음과 같은 결과를 얻었다. 1) dopamine은 소장의 모든 부위에서 자발적 수축성을 억제하였으며, 이러한 dopamine의 작용은 회장을 제외한 다른 부위에서 tetrodotoxin에 의하여 유의하게 감소하였다. 2) domperidone은 소장의 모든 부위에서 dopamine의 억제작용에 길항적으로 작용하였으며, tetrodotoxin을 전처치하면 회장을 제외한 다른 부위에서 domperidone의 길항작용은 완전히 소실되었다. 3) CCK-8는 소장의 모든 부위에서 dopamine의 작용을 감소시켰으며, tetrodotoxin을 전처치하면 CCK-8의 작용은 유의하게 감소되었다. 이상의 결과로 미루어 보아 dopamine은 십이지장구를 포함한 모든 소장의 수축성을 억제하며, CCK-8는 dopamine의 억제 작용을 감소시키는데, 이러한 작용들은 장관내 신경계를 거쳐서 간접적으로 일어나는 것으로 생각된다.

Cholelithiasis, duodenal ulcer, duodenal perforation and tumor invasion may lead to choledochoduodenal fistula (CDF). CDF often has no specific symptoms and may be incidentally detected in an upper gastrointestinal radiographic study or endoscopy; but in some cases, it may be accompanied by recurrent cholangitis and liver abscess. In this paper, a case of recurrent liver abscess caused by CDF is reported. A 62-year-old female was admitted to the authors' hospital because of right upper quadrant pain and fever. The abdominal computed tomography showed a liver abscess in the right lobe. A duodenal fistulous orifice was detected with endoscopy, and a contrast was injected through the duodenal orifice using a catheter under fluoroscopy. The injection of the contrast revealed a fistulous track between the duodenal bulb and the common hepatic duct. In fistulas complicated by recurrent liver abscess, surgery or medical management may be needed. The CDF in this case study was treated via endoscopic clipping.

Brunneroma, also known as Brunner's gland adenoma or harmatoma, is a very rare benign tumor of the duodenum, which is usually asymptomatic, and is discovered incidentally during endoscopic exam. These lesions are most commonly located in the duodenal bulb and clinical manifestations are variable. We report on a case of a large Brunner's gland adenoma in a 54-year-old man, which was successfully removed by endoscopic resection without complications, such as bleeding or perforation. Microscopically, it was composed entirely of variable Brunner's gland.

A 55-year-old man was admitted to the hospital for jaundice. Computed tomography (CT) scans showed a diffuse mass in the pancreas and peripancreatic area, with infiltration to of the whole pancreas, and overall reduced enhancement compared to normal pancreas. Esophagogastroduodenoscopy revealed elevated mucosal lesion covered hyperemic mucosa at duodenal bulb and ulcerative lesion at body of stomach. Endoscopic ultrasonography revealed an irregular mass with unclear boundaries was observed within the pancreas. Abrupt narrowing of mid to distal common bile duct was seen and the stricture was caused by compression of pancreatic mass. Plastic stent was inserted and clinical improvement was achieved including resolution of jaundice. The patient is currently being treated with combination of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone. We report a case of primary pancreatic lymphoma presenting with obstructive jaundice.

여러 개의 자석을 삼킨 경우 자석들이 서로 잡아당겨 압력 괴사로 인한 장폐쇄, 장천공, 누공 형성 등의 합병증을 일으킬 수 있다. 따라서 영 유아나 정신과적인 문제가 있는 큰 아이의 경우 자석이나 자석이 포함된 장난감과 같은 물건들을 멀리하고, 자석을 삼킨 경우에는 즉시 확인해 보아야 한다. 저자들은 1년 전부터 주기성 구토를 호소했던 중등도 정신지체를 가진 12세 남아에서 삼킨 장난감 자석 4개로 인해 위-십이지장 누공을 형성하였고 수술 후 호전된 1예를 치험하였기에 보고하는 바이다.

A human Echinostoma hortense infection was diagnosed by gastroduodenoscopy. An 81-year-old Korean male, living in Yeongcheon-shi, Gyeongsangbuk-do and with epigastric discomfort of several days duration, was subjected to upper gastrointestinal endoscopy. He was in the habit of eating fresh water fish. Two live worms were found in the duodenal bulb area and were removed using an endoscopic forcep. Based on their morphological characteristics, the worms were identified as E. hortense. The patient was treated with praziquantel 10 mg/kg as a single dose. The source of the infection in this case remains unclear, but the fresh water fish consumed, including the loach, may have been the source. This is the second case of E. hortense infection diagnosed by endoscopy in Korea.

Purpose: Safety pin ingestion is common in some regions of the world and may lead to severe morbidity and mortality. The aim of this study was to present some practical suggestions for ingested safety pins using an accompanying algorithm, presented for the first time in the literature to the best of our knowledge. Methods: Twenty children with ingested safety pins during a 4-year period were retrospectively included in the study. Results: Median age of patients was 9.5 months (interquartile range, 6.3-14 months), and 70% were girls. On endoscopic examination, safety pins were observed in the stomach (25%), duodenal bulb (20%), upper esophagus (15%), middle esophagus (10%), and second part of the duodenum (10%) but were not observed in 20% of the cases. Safety pins were removed using endoscopy in 15 cases (75%). In four cases (20%), no safety pin was observed on endoscopic examination. In one case (5%) involving a 6-month-old infant, the safety pin could not be removed although it was observed using endoscopy. No surgical intervention was needed for any patient. No complications such as perforation or deaths developed, except for erosions, due to the foreign body removal procedure. Conclusion: Safety pins are easily removed endoscopically. The best option is to remove the safety pin using endoscopy while it is still in the esophagus and stomach. For this reason, endoscopic procedures should be performed as soon as possible in children who have ingested safety pins.

This study was carried out to understand the macroscopic aspects of the digestive system symptoms occurring after taking oriental herb complex decoction as observing morphological changes in esophagus, stomach and duodenal bulb by endoscopy of upper gastrointestinal tract when these symptoms developed. The subjects of this study were 46 patients (male 22, female 24, mean age : $54.72{\pm}14.26$ years) who were chosen among ones who took oriental herb complex decoction for medical care and developed symptoms related to the gastrointestinal tract while taking an oriental herb decoction, which were assumed that the digestive symptoms were newly developed because of administration. The subjects were given morphological examination by endoscopy of the upper gastrointestinal tract. As a result of the endoscopy operated due to the digestive symptoms developed during the administration of oriental herb decoction, there were 2 cases of esophagitis, 5 cases of acute gastritis, 1 case of chronic gastritis A type, 15 cases of chronic gastritis B type, 1 case of duodenitis, 1 case of gastric ulcer, 1 case of gastric polyp, 2 cases of intestinal metaplasia, 1 case of gastric ptosis and 17 cases of normal findings which didn't have any abnormality macroscopically with endoscopy. With regards to the patients who complained of the digestive symptoms after taking oriental herb decoction, it has been found that the symptoms occurred as the oriental herbal medicine taken by the patients who had the digestive symptoms at ordinary times influenced on the gastrointestinal tract. Especially, many of them were had chronic gastritis and functional dyspepsia in the past. The disease accompanying macroscopic lesions at endoscopy which occurred due to the oriental herb decoction as direct cause, was acute gastritis, and it was the prescription to cure the pains and inflammations of skeletomuscular disease.
