Prediction of the Response to Proton Pump Inhibitor Treatment Using Wireless Ambulatory pH Monitoring in Patients with Globus Sense / 대한소화기학회지

BACKGROUND/AIMS: Globus is a persistent or intermittent non-painful sensation of a lump or foreign body in the throat and a commonly encountered clinical condition. We aim to evaluate the prevalence of gastroesophageal reflux disease (GERD) and to determine the parameters for predicting the response to treatment with proton pump inhibitor (PPI) using wireless pH monitoring in patients with globus sense. METHODS: We retrospectively reviewed the medical records of 37 patients with atypical GERD symptoms. A total of 27 patients with dominant globus sense were enrolled. Endoscopic examination and 48-hour wireless esophageal pH monitoring were performed, and the patients underwent a therapeutic trial of full dose PPIs daily over a period of 4 weeks. RESULTS: Both typical and atypical GERD symptoms co-existed in 14 patients (51.9%, 14/27). According to ROME III criteria, 19 patients (70.4%, 19/27) were diagnosed as GERD. Twelve patients (44.4%, 12/27) were PPI responders. A significant difference in the frequency of symptom index (+) or symptom associated probability (+) was observed between the PPI responder group and the non-responder group (p<0.01). CONCLUSIONS: In patients with globus sense, 70.4% were diagnosed with GERD. Symptom index/symptom associated probability in wireless ambulatory pH monitoring was a good objective parameter for PPI responder.

Current Status and Clinical Impact of Pediatric Endoscopy in Korea / 대한소화기학회지

BACKGROUND/AIMS: In pediatrics, endoscopic examination has become a common procedure for evaluation of gastrointestinal presentations. However, there are limited data on pediatric endoscopy in Korea. The aim of this study was to analyze the current status and clinical impacts of endoscopic examination in children and adolescents. METHODS: We retrospectively reviewed the medical records of outpatients who visited the tertiary hospital. Patients under 18 years of age who underwent endoscopy were included. Endoscopic findings were classified as specific and normal based on gross findings. Specific endoscopic findings were reflux esophagitis, peptic ulcers, and Mallory-Weiss tear. Other findings included acute gastritis classified according to the updated Sydney system. RESULTS: In 722 of 330,350 patients (0.2%), endoscopic examination (554 esophagogastroduodenoscopies [EGDs], 121 colonoscopies, 47 sigmoidoscopies) was performed between January 2008 and January 2013. In EGD, abdominal pain was the most frequent presentation (64.1%). The most common diagnosis was gastritis (53.2%), followed by reflux esophagitis. The frequency of peptic ulcer disease was 12.8%. Frequent symptoms leading to colonoscopic examination were abdominal pain, diarrhea, and hematochezia. In colonoscopy, a negative result was more likely in children younger than 7 years old. After the procedure, the diagnostic yield of EGD and colonoscopy was 88.1% and 45.8%, respectively, and the rate of change in management was 67.1%. CONCLUSIONS: In pediatrics, endoscopic examination was useful for the choice of therapeutic strategy and it would be a standard method for evaluation of gastrointestinal presentation.
