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.

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.

The pathophysiology of Gastroesophageal reflux disease (GERD) has been known that it is developed when the offense-primarily the gastric acid-pepsin content of the refluxate-overcomes a 3-tiered esophageal protective defense. consisting of antireflux mechanisms, luminal clearance mechanisms, and tissue resistance. Laryngopharyngeal reflux (LPR), which is known as an extraesophageal variant of GERD, has been considered to be developed by transient lower esophageal sphincter relaxation (TLESR), direct mucosal injury by gastric contents, more sensitive mucosa compared to esophagus, and absence of buffering effect and aggravation of the injury due to pepsin. However, hypothesis of the pathophysiology in both entities are numerous and still lack of understanding for being a theory. There is no conflict that understanding the pathophysiology is necessary for resolving the problems of these diseases and numerous studies and results have been releasing. This review could provide clinicians dealing with GERD and LPR with applicable new information and help for overcoming the clinical obstruction.

Background and Objectives: Gastric acid reflux is known to be the most important cause of contact granuloma. Therefore, anti-gastric acid reflux medication has been used as the first line treatment although there are other treatment methods such as surgery or steroid injections. Actually, the role of surgery in the treatment of contact granuloma has not been established clearly. The purpose of this study was to evaluate the effectiveness of surgical treatment for contact granuloma. Materials and Methods: We retrospectively reviewed the medical records of 14 patients who were diagnosed with contact granuloma and treated with surgery from 2011 to July 2016 at Hanyang University hospital. Results: Of 14 patients, 9 (64.3%) were male and 5 (27.4%) were female. The mean age was 53.8 (${\pm}6.1$) years. The main symptoms were voice change followed by globus, dyspnea, and asymptomatic. Mean Reflux Finding Score (RFS) before surgery was 13.5 and mead Reflux Symptom Index (RSI) was 10.4. The causes of surgery were inadequate response to proton pump inhibitor (PPI) in 4 cases, airway obstruction with large granuloma in 8 cases, and differential diagnosis in 2 cases. Of 14 patients, recurrence occurred in 8 (53.3%) patients after surgery. In 8 recurrent cases, 5 patients showed complete remission and 3 patients showed partial remission with PPI medication. Conclusion: The role of surgery in the treatment of contact granuloma might be limited due to high recurrence rate.

The term laryngopharyngeal reflux (LPR) refers to the backflow of food or stomach acid back up into the larynx (the voice box) or the pharynx (the throat). Esophagopharyngeal reflux is suggested as an etiologic factor in laryngeal disease. To examine a possible esophageal basis for laryngopharyngeal symptoms, we studied 48 patients with persistent laryngopharyngeal symptoms, and 12 relative control subjects. Patients were evaluated for cervical symptoms by questionnaire and underwent gastrofiberoscopy, fiberoptic laryngoscopy, esophageal manometry and 24-hour ambulatory double-probe pH monitoring. We found LPR in fourteen out of 48 patients with cervical symptoms (29%). The LPR group consisted of nine men and five women. The symptoms that LPR patients complained were throat lump sensation, hoareness, sore throat, throat clearing, chronic coughing and dysphagia in order of frequency, and they were not different significantly from non-LPR patients. The laryngoscopic findings in LPR patients were posterior erythema, laryngeal edema and diffuse erythema, and there was also no significant difference between LPR group and non-LPR group. There was statistically significant correlation between LPR and gastroesophageal reflux (GER). We concluded that there is no pathognomonic symptoms or laryngoscopic findings in diagnosis of LPR, and 24-hour ambulatory double-probe pH monitoring is an essential diagnostic tool in LPR.

Gastroesophageal reflux is thought to be an important etiology of the various upper aerodigestive tract disease. To investigate the role of gastric acid and pepsin as an etiologic factor of laryngotracheal stenosis, and the difference of injury by synthetic gastric juice between in ciliated respiratory epithelium and in squamous epithelium, experimental study was carried out using rabbits. Mucociliary transport affected by synthetic gastric juice was also studied in dogs. Synthetic gastric juice of low pH caused serious damage and Impairment of mucociliary transport in the epithelium of the larynx and trachea. Gastric acid played major role in the mucosal damage. Squamous epithelium of vocal folds and pharynx was more resistant to synthetic gastric juice than respiratory epitheium. In conclusion, gastroesophageal reflux may be an etiologic factor in the developement of laryngotracheal stenosis, so the adequate management is necessory In patients of laryngotracheal stenosis.

Objectives: The purpose of this study was to confirm the effects of Liriope platyphylla extract on relieving Gastroesophageal reflux disease (GERD) through regulation of acid secretion. Methods: 8-week-old ICR mice were divided into untreated control group (Ctrl), GERD elecitation group (GERDE), Omeprazole administrate group before GERD elicitation (OMA), and Liriope platyphylla extract administrate group before GERD elicitation (LPA). After inducing GERD, gross observation and histological examination were performed and ATP6V1B1 (ATPase H+ Transporting V1 Subunit B1), GRPR (Gastrin-releasing peptide receptor), COX-1 (Cyclooxygenase 1), 8-OHdG (8-hydroxy-2'-deoxyguanosine), Cathelicidin, p-JNK (phospho c-Jun N-terminal kinase) were observed to confirm the damage defense effect of the esophageal mucosa, acid secretion regulation, antioxidant, anti-inflammatory, mucosal protection, and apoptosis regulation Results: OMA and LPA showed lower levels of damage compared to GERDE in gross observation and histological examination. ATP6V1B1, GRPR, and 8-OHdG showed lower positive reactions in OMA and LPA than in GERDE. COX-1 were less positive in GERDE and OMA than in Ctrl, but showed higher secretion in LPA than in Ctrl. Cathelicidin showed a decreased positive reaction in GERDE, OMA and LPA compared to Ctrl, but the decrease in positive reaction was smaller in OMA and LPA compared to GERDE. p-JNK showed increased positive reaction in GERDE, OMA and LPA than in Ctrl, but the increase in the positive reaction was smaller in the OMA and LPA compared to GERDE. Conclusions: The effects of Liriope platyphylla extract on esophageal mucosal damage protection, acid secretion regulation, antioxidant, anti-inflammatory, mucosal protection and apoptosis regulation were confirmed.

1998년 5월부터 1999년 4월까지 상부소화기내시경 검사상 위궤양 또는 십이지장 궤양으로 진단된 환자 중 24시간 보행성 식도산도검사를 완료한 57명을 대상으로 하여 다음과 같은 결과를 얻었다. 1) 전체 57명 중 31명(54.2%)에서 병적 산역류가 관찰되었다. 반면 대조군에서는 22명 중 5명으로 22.7%였다. 2) 소화성 궤양에서 역류의 양상은 대조군과 다른 경향이 있으며 3) 소화정 궤양 환자에서 증상만으로 위식도 역류의 유무를 평가하기는 어렵다. 4) 십이지장 궤양, 남자, H. pylori가 위식도 역류의 의미 있는 변수로 생각된다. 이상의 결과로 소화정 궤양의 진단시와 치료 후 역류성 식도염 외에 위식도 역류의 유무를 확인하는 것이 H. pylori 제균치료 후 소화기 증상이 남아 있는 환자들의 치료에 도움이 될 것으로 생각되며, 이 경우 24시간 보행성 식도산도검사가 유용할 것이다.
