We report a case of severe(gradeV) unilateral vesicoureteral reflux(VUR) without any renal damage in a 6-month-old boy through the early sil)ling screening test for VUR, whose old brother had reflux nephropathy. The early detection of VUR aroused us to take special precautions to prevent urinary tract infection in this patient. We believe that this approach was helpful to reduce the risk of renal damage in this patient and are reporting the case with a brief review of related literatures. It is our firm suggestion that screening for vesicoureteral reflux should be carried out in every child who has siblings with refluf nephrouathy.

It was evaluated the inhibitory action of quercetin-3-O-${\beta}$-D-glucuronopyranoside (QGC) on reflux esophagitis and gastritis in rats. QGC was isolated from the herba of Rumex Aquaticus. Reflux esophagitis or gastritis was induced surgically or by administering indomethacin, respectively. Oral QGC decreased ulcer index, injury area, gastric volume, and acid output and increased gastric pH as compared with quercetin. Furthermore, QGC significantly decreased gastric lesion sizes induced by exposing the gastric mucosa to indomethacin. Malondialdehyde levels were found to increase significantly after inducing reflux esophagitis, and were reduced by QGC, but not by quercetin or omeprazole. These results show that QGC can inhibit reflux esophagitis and gastritis in rats.

Objective: This study reports on a treatment case of Soojeom-san plus Jeungmiyijin-tang (SJJI) on gastroesophageal reflux disease with hiatal hernia. Method: We considered a male patient suffering from gastroesophageal reflux disease with hiatal hernia because of blood stasis and damp-heat of the spleen and stomach pattern and prescribed SJJI. The progress was evaluated using the frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) score, and the visual analogue scale for abdominal pain, sore stomach, and other symptoms. Results: The patient's symptoms, which included abdominal pain, sore stomach, dyspepsia, anorexia, insomnia, etc., almost disappeared. Conclusion: SJJI can be used for patients who have a chronic condition of gastroesophageal reflux disease with hiatal hernia because of blood stasis and a pattern of damp-heat of the spleen and stomach.

This study was conducted to examine the current status of traditional korean medicine studies on gastroesophageal reflux disease in Korea, identify deficiencies, and suggest the direction of future medicine research methods to lay the foundation for traditional korean medicine treatment. All domestic papers on the korean traditional treatment of gastroesophageal reflux disease were selected among the literature published until August 2022 in six domestic databases. A total of 52 selected research data were classified into experimental research papers, clinical research papers, and review papers. In experimental papers, to evaluate the effectiveness of treatment, improvement of esophageal mucosal lesions, anti-inflammatory mechanisms, antioxidant mechanisms, esophageal mucosal protection mechanisms, gastric peristalsis control, and gastric acid secretion inhibition mechanisms were used as evaluation measures. In the clinical research paper, the basis for diagnosis of cases was clinical symptoms through medical history listening and diagnosis through visits to hospitals in the past. The average treatment period was 40.7 days, and the duration of treatment was not significantly affected by the duration of the disease. The most widely used Korean medicine treatment intervention was herbal medicine. There were 3 literature review studies, 3 systematic literature review and meta-analysis studies, 1 comparative review study for clinical trial guideline development, all using Chinese papers. This study included all domestic papers on gastroesophageal reflux disease to identify the research trend of the Korean oriental medicine community, and based on this, it is meaningful to confirm areas that need to be supplemented in future research plans.

Purpose: The hepatobiliary scan is the examination which is the possibility of knowing the function of liver, gall bladder and closing of the biliary tract. Also, after subtotal gastrectomy, the increased gastric-bile reflux is known as the primary reason of reflux gastritis. In this study, according to changing the acquisition method, we tried to prove the reflux time and reflux index in patients who underwent subtotal gastrectomy. Materials and Methods: From Oct 2008 to Jan 2009, 72 patients with subtotal gastrectomy who took the hepatobiliary scan (man: 52, woman: 20, age range: 31-77, mean age: $60.5{\pm}7$) in our department. We used the radiopharmaceutical $^{99m}Tc$-mebrofenin 185 MBq/0.5 cc. After 5 minutes, we acquired 300,000 counts anterior image on supine, and then we acquired right lateral and $45^{\circ}$ LAO position by using the time setting method. We acquired 30 min, 60 min, 90 min, 120 min and fatty meal by the same method. We painted the ROI of liver, GB and CBD on 30 min anterior image and LAO image in patients had occurred the bile juice reflux. And then we painted the ROI of stomach on others image. We calculated the reflux index from those values. Results: According to this study, we found out 40 patients (55.6%) who had occurred the gastric-bile juice reflux (1 person from 30 min, 7 persons from 60 min, 4 persons from 90 min, 28 persons from after fatty meal). Hourly, the bile reflux highest level is 6 persons from 60 min, 2 persons from 90 min, 32 persons from fatty meal among those people. The reflux index of anterior is 0.85-23.36% (mean 6.53%). The reflux index of LAO is 1-29.13% (mean 8.89%). By visual assessment, we can distinguish that there were 26 of the 40 patients (65%) had occurred the reflux on LAO image more than anterior image. Conclusion: We find out that the patients with subtotal gastrectomy had occurred gastric-bile juice reflux more than 50% from hepatobiliary scan. And after eating fatty meal, we can know that it's the most possible to occur the gastric-bile juice reflux. When it happened, we have to change the acquisition method to reduce the overlap between colon and stomach. This study will be more valuable in diagnosis.

Objectives : In this study, we investigated the protective effects of Charybdis japonica (C. japonica) water extract on the acute reflux esophagitis in rat models. Methods : Twenty rats were divided into four groups for examination: normal control group (n=6), the reflux esophagitis group (n=6), reflux esophagitis treated with positive control group (ranitidine 40 mg/kg, n=6), reflux esophagitis treated with C. japonica group (100 mg/kg, n=6). All rats fasted for 18 hr and then were induced with reflux esophagitis by a pylorus and forestomach ligation operation. After 4 hr, the rats were sacrificed. The proinflammatory cytokine and proteins expression measured by western bolt assay, and the histopathological analysis of the esophageal mucosa measured by hematoxylin and eosin staining. Results : C. japonica administration significantly was protecting esophageal mucosal damage upon histological analysis of reflux esophagitis in rats. The C. japonica treatment confirmed the protection of the reduction of claudin-5, an evaluation index of the damage of tight junctions in the reflux esophagitis. C. japonica was also found to inhibit the expression of proteins such as COX-2 and TNF-α in the rat esophagus. C. japonica markedly attenuated the activation of NF-κB and phosphorylation of IκBα at the same time. Conclusion : These results indicated that C. japonica suppressed the development of esophagitis through the modulation of inflammation by regulating NF-κB activation. Based on these findings, we concluded that C. japonica can prevent reflux esophagitis.

Purpose: Reflux esophagitis is a disease caused by the reflux of stomach contents and stomach acid etc. into the esophagus due to defect in the lower esophageal sphincter and is currently increasing worldwide. This study was conducted to evaluate the effect of a mixture of Citrus Reticulata and Scutellariae Radix (CS) extract on acute reflux esophagitis in rats. Methods: Rats were divided into five groups for examination: normal group (Normal, n = 8), water-treated acute reflux esophagitis rats (Control, n = 8), tocopherol 30 mg/kg body weight-treated acute reflux esophagitis rats (Toco, n = 8), CS 100 mg/kg body weight-treated acute reflux esophagitis rats (CS100, n = 8), CS 200 mg/kg body weight-treated acute reflux esophagitis rats (CS200, n = 8). The experimental groups were administrated of each treatment compounds and after 90 min, acute reflux esophagitis was induced through surgery. Rats were sacrificed 5 h after surgery. We measured the level of reactive oxygen species (ROS) in serum and analyzed the expression of nicotinamide adenine dinucleotide phosphate, inflammatory, and tight junction-related proteins by western blot in the esophageal tissues. Results: CS administration significantly protected the esophageal mucosal damage due to reflux esophagitis, and the level of ROS in the serum was significantly reduced with CS administration as compared to Control. In addition, CS administration significantly suppressed mitogen-activated protein kinase (MAPK or MAP kinase) and nuclear factor-kappa B (NF-κB) pathways and increased protein expressions of tight junction protein. Conclusion: These results suggest that the CS not only regulates the expression of inflammatory proteins by inhibiting oxidative stress, but also reduces damage to the esophageal mucosa by inhibiting the expression of tight junction proteins.

Gastroesophageal reflux disease(GERD) refers to the varied clinical manifestations of reflux of stomach and duodenal contents into the esophagus and is preferable to the 'reflux esophagitis'. Clinical symptoms of reflux esophagitis are heartburn, dysphagia, blood loss, abdominal pain, nocturnal wheezing, coughing, hoarseness. We applied oriental medicines to patient who had reflux esophagitis. we treated them with herb-medication, acupuncture, moxa therapy and aroma therapy for about 2 months. During this period, we observed that symptoms had been improved.

Although there is a wide range of diseases caused by gastric acid reflux and the number of cases is on the rise, it is difficult for the laryngologist to make the correct diagnosis. The treatment for laryngopharyngeal reflux can be grouped into 3 categories - changes in lifestyle, medication, and surgery. The medication used to treat laryngopharyngeal reflux are prokinetic agents and acid supressive agents such as antacids, H2 blockers, and PPIs(Proton pump inhibitor). Rabeprazole sodium($Pariet^{\circledR}$) is a newly developed agent belonging to the PPI group, but in contrast with the existing drugs such as omeprazole, lansoprazole, pantoprazole, has a low dependency on CYP2C19 during the metabolic cycle. Thus, it is known to have a quick but fixed antiacid effect and less individual differences. We analyzed 2166 patients from 32 hospitals who were prescribed $Pariet^{\circledR}$ from May, 2001 to April, 2002. The patients were divided into 4 groups according to the duration of treatment - Group 1: 1-14 days, Group 2: 15-28 days, group 3: 29-56 days, Group 4: more than 56 days. The cases were then analyzed for improvement of 8 symptoms(heart bum, regurgitation, chronic cough, hoarseness, globus sensation, chronic throat clearing, sore throat, and dysphagia), improvement on laryngoscope, usefulness to the doctor, and complication development. Of the total of 2116 patients, 1627(75.1%) cases showed at least 50% improvement of symptoms and the amount of improvement increased according to the duration of medical treatment. Most of the patients showed objective improvement on the laryngoscope, with 32.9% showing significant improvement and 38.7% showing moderate improvement. 37.6% of the doctors questioned replied that $Pariet^{\circledR}$ was very useful and 50.3% said it was useful, showing that most were satisfied with the treatment results. The complications known to develop after taking PPI are headache, nausea, diarrhea, abdominal pain, constipation, dizziness, fatigue, and of these, only a small percentage of the patients complained of mild headache. $Pariet^{\circledR}$ has shown to be a relatively safe and effective drug for the treatment of laryngopharyngeal reflux.

Fundoplication is accepted as an effective treatment of gastroesophageal reflux disease. The recent results of laparoscopic fundoplication demonstrated safety and less morbidity, shorter hospital stay and less pulmonary complication compared to the open operation. Laparoscopic fundoplication has been our first choice of operation for gastroesophageal reflux disease since 2003. Among 29 cases, there were 2 conversion cases because of severe distension of transverse colon and hepatomegaly. We studied 27 consecutive patients operated upon from January 2003 through December 2004. There were 15 boys and 12 girls, ages from 1.5 months to 12 years (median 25.3 months). Body weight ranged from 2.9 kg to 37 kg (median 9.8 kg). Neurological abnormalities were present in 23 patients. Indications for surgery included medically refractory reflux associated with vomiting, pneumopathy, otorhinolaryngologic pathology, failure to thrive, esophagitis, apnea and bradycardia. We used 4-5 trocars of 5 mm or 12 mm with $30^{\circ}$ telescope and performed the Nissen technique in all patients. In neurological impaired patients, gastrostomy tube was placed at the time of fundoplication. Median operative time was 130 minutes (70 - 300 minutes). There was no mortality nor intraoperative complication. Twenty-six patients were followed for median of 19 months (8 - 31 months). Four patients (15.4 %), who were all neurological impaired, developed recurrent symptoms of gastroesophageal reflux disease. Two of these patients had reoperation (1 laparoscopic approach, 1 open method). There were significant increases in body weight in 11 patients after fundoplication. Laparoscopic fundoplication is acceptable as a safe and effective method for gastroesophageal reflux disease.
