선천성 비후성 유문 협착증의 진단에 있어서 상부 위장관 내시경술의 역할 = Esophagus, Stomach & Intestine;The Role of an Upper Gastrointestinal Endoscopy in the Diagnosis of Congenital Hypertrophic Pyloric Stenosis

다국어 초록 (Multilingual Abstract)

Background/Aims: In 1977, Teele and Smith reported their positive experience using an ultrasonographic in the evaluation of Congenital Hypertrophic Pyloric Stenosis (CHPS). Since that time, ultrasonography has been advocated by some as the diagnostic procedure of choice, although a number of false-negative cases have been encountered at any rate, in 1994, Becker reported that an endoscopy was far more accurate than an ultrasonography, the diagnosis being made in 97% and 81% of the cases. Therefore, we performed a prospective study to evaluate the diagnostic value of an upper gastrointestinal endoscopy in CHPS patients. Methods: We reviewed the clinical records of 12 pediatric patients experiencing vomiting, who had visited Pusan National University Hospital from January 1993 to March 1997. We performed on upper gastrointestinal endoscopy and abdominal ultrasonography simultaneously in order to evaluate the diagnostic value of an upper gastrointestinal endoscopy in CHPS patients. Results: The male to female ratio was 11: 1. In 7 of 12 patients, 58%, vomited within 4 weeks after birth. Diagnostic sensitivity by abdominal ultrasonography was about 75%, and by upper GI endoscopy, almost 100%. Associated lesions were discovered in 5 cases, 3 esophagitis and 2 gastritis in the upper GI endoscopy. Conclusions: The upper GI endoscopy was more accurate in the diagnosis of CHPS than the ultrasonography, and was more effective in the diagnosis of associated lesions.
