Purpose: The aim of this study was to evaluate the clinical characteristics, endoscopic findings and risk factors related to the upper gastrointestinal bleeding (UGIB) seen in full-term infants. Methods: A clinical analysis for 9 cases with UGIB confirmed by endoscopy was carried out retrospectively. Patients were admitted to the Department of Pediatrics, Eulji Hospital, from January to December 2003. Results: UGIB from gastric or duodenal mucosal lesions has been seen in 0.13% in newborns infants. All patients were full-term AGA neonates without asphyxic findings at birth. Hematemesis, melena or recurrent vomiting developed within $4.4{\pm}3.8days$ after birth. Vital sign and laboratory test was normal on admission. Endoscopic findings showed hemorrhagic gastritis in 6 cases and peptic ulcers in 3 cases. All patients were successfully managed by medical treatment for $18.6{\pm}5.0days$. On treatment, clinical symptoms improved within $0.9{\pm}0.3days$. Follow-up endoscopy was not performed because there was no recurrence of symptoms in all patients. Case mothers had no history of gastritis, ulcer or anti-ulcer medications before and during pregnancy. Conclusion: If the healthy full-term infants express UGIB within a few days after birth, it is necessary to take careful history of family, mother and delivery process and to practice endoscopy for mucosal lesions of the patients. A follow-up endoscopy dose not seem to be necessary if the infant is clinically well.

위궤양 증상일 수 있으니 먼저 내시경검사를 한번 받아보십시오. "이렇게 소화가 안되는데, 혹시 위암이 아닌가요? 등. 흔히 우리가 진료실에서 나누는 얘기들이다. 어떤 의사는 위염이니깐 1~2개월 치료해야 한다고 말하기도 하고, 또 어떤 의사는 남들 다 있는 위염이니깐 안 아프면 두고 봐도 된다고 하기도 하고, 또 어떤 경우에는 위염이 위암이 되니깐 위내시경 검사를 자주 받아야 된다고 하기도 한다. 심지어 위암의 위험인자라고 하면서도 치료는 필요 없다고 얘기하기도 한다.

Recently we have experienced an about 15cm long foreign body lodged at trachea in the adult patient, it was a toothbrush bar of which the head had been removed by patient himself. Its tip was shown above vocal cord on videogastroscope, so we removed the toothbrush bar by using the foreign body forcep. So we report it with review of literature.

Purpose: The Helicobacter pylori stool antigen (HpSA) enzyme immunoassay is a non-invasive test for the diagnosis and monitoring of H. pylori infection. But, there are few validation studies on the HpSA test after eradication in children. The aim of this study was to assess the diagnostic accuracy of HpSA enzyme immunoassay for the detection of H. pylori to confirm eradication in children. Methods: From January 2001 to October 2003, 164 tests were performed in 146 children aged 1 to 17.5 years (mean $9.3{\pm}4.3$ years). H. pylori infection was confirmed by endoscopy-based tests (rapid urease test, histology, and culture). All H. pylori infected children were treated with quadruple regimens (Omeprazole, amoxicillin, metronidazole and bismuth subcitrate for 7 days). Stool specimens were collected from all patients for the HpSA enzyme immunoassay (Primier platinum HpSA). The results of HpSA tests were interpreted as positive for $OD{\geq}0.160$, unresolved for $$0.140{\leq_-}OD$$<0.160, and negative for OD<0.140 at 450 nm on spectrophotometer. Results: 1) One hundred thirty-one HpSA tests were performed before treatment. The result of HpSA enzyme immunoassay showed three false positive cases and one false negative case. The sensitivity, specificity, positive predictive value, and negative predictive value of HpSA enzyme immunoassay before treatment were 96.4%, 97.1%, 90%, and 99%, respectively. 2) Thirty-three HpSA enzyme immunoassay were performed at least 4 weeks after eradication therapy. The results of HpSA enzyme immunoassay showed two false positive cases and one false negative case. The sensitivity, specificity, positive predictive value, and negative predictive value after treatment were 88.9%, 91.7%, 80%, and 95.7%, respectively. Conclusion: Diagnostic accuracy of the HpSA enzyme immunoassay after eradication therapy was as high as that of the HpSA test before eradication therapy. The HpSA enzyme immunoassay was found to be a useful non-invasive method to confirm H. pylori eradication in children.

Purpose: The purpose of this study was to verify the effect of aromatherapy hand massage on the anxiety of gastroscopy clients. Method: The data were collected during the period from March 10 to May 20, 2004 at S-Hospital in Kyungi-Do. There were sixty subjects, 30 for the experimental and 30 for the control group. The data were analyzed by descriptive statistics, t-test, $X^2$-test and paired t-test with SPSS program. Result: The pulse rate was reduced significantly, but there were no significant differences in the systolic and diastolic blood pressure between two groups. The status anxiety of experimental group was lower than the control group, but there was no significant difference statistically. Conclusion: Aromatherapy could be useful in the nursing practice, and be utilized as a way of nursing intervention to reduce anxiety of the client in specific clinical situations.

Small cell carcinoma of esophagus is a rare malignant tumor Recently we experienced one case of small cell carcinoma in mid thoracic esophagus. The patient was a 68 year old male patient. On preoperative endoscopic biopsy, neuroendocrine carcinoma was suspected. Esophagectomy and esophagogastrostomy was performed. Postoperative course was uneventful and patient was discharged without specific complicalion.

As rates of gastric cancer. fatness. and GERD (chronic gastric esophageal reflux disease) patients have been increased in the world, suturing mechanism using endoscope has been focused. which is the medical instrument to apply stitches and suturing inside the body, since it helps the patients lessen pains and reduce operation time. This paper deals with mechanism design, which makes it possible to apply multiple suturing without the repeat of inserting and removing the endoscope. This successive suture mechanism includes gripper, linkage, rotational part, and articulation part. Also, the mechanism is operated through 4mm one-side channel attached to the endoscope by means of pulling wires.

Basaloid-squamous cell carcinoma, a biologically high-grade variant of squamous cell carcinoma, is predominantly located at upper aerodigestive tract but it is extremely rare in the esophagus. Recently we experienced a case of basaloid-squamous cell carcinoma of esophagus. A 64 year-old man was referred to our hospital because of mucosal nodularity at 35 cm apart from the incisor in endoscopic examination. Result of Biopsy was squamous cell carcinoma. Left transthoracic esophagectomy was performed. Histologically, the lesion of tumor was basaloid-squamous cell carcinoma and no lymph node metastasis was found.

The early detection of early gastric cancer (EGC) is important. However, the sensitivity of conventional white light imaging (WLI) in detecting EGC had been reported to range only from 77% to 84%. Although the resolution of endoscopes has been remarkably developed, precancerous lesions such as adenomas and microscopic early cancers are difficult to diagnose with general endoscopy. Linked Color Imaging (LCI) magnifies the differences in color for easy detection. Therefore, it produces a bright image from a distance and is performed for screening endoscopy. The 410 nm wavelength of BLI (Blue Light Imaging) helps to detect cancer by showing microstructure and microvessels in the mucosal superficial layer. This review will focus on the utility of Image enhanced endoscopy (IEE) techniques in diagnosis of gastrointestinal cancer.
