Objective To evaluate the diagnostic significance of esophageal minimal change in gastroesophageal reflux disease (GERD) and explore its clinical characteristics.Methods From May to September in 2013,patients with minimal esophageal mucosa changes including esophageal mucosa rough,white secretin adhesion,erythema,edema,increased brittleness,blurring of the Z line or zigzag looking and blurring of paliform blood vessel,or patients with Los Angeles classification (LA) which were identified by endoscopy were enrolled.The subjects received gastroesophageal reflux disease questionnaire (GcrdQ) investigation and the related history were collected.The total score of GerdQ over eight was set as the criteria for GERD diagnosis.The R × C chi-square test was performed for statistical analysis.Results A total of 417 valid questionnaires were completed.Of which,202 cases were in minimal change group,176 were in LA A group and 36 were in LA-B group.The diagnostic rate of GERD in minimal change group was 20.3％ (41/202),which was lower than that of LA-A group (74.4％,131/176) and LA-B group (83.3 ％,30/36),and the differences were statistically significant (x2 =129.144,P＜0.01).The incidences of heartburn in minimal change group,LA A group and LA-B group were 25.7％ (52/202),62.5％ (110/176) and 86.1％ (31/36),respectively.The incidences of reflux were 29.7％ (60/202),67.6％ (119/176) and 75.0％ (27/36),respectively.The incidences of non cardiac chest pain were 5.4％ (11/202),22.2％ (39/176) and 22.2％(8/36),respectively.The incidences of heartburn,reflux and non cardiac chcst pain of minimal change group were all lower than those of LA A group and LA-B group,and the differences were statistically significant (x2 =75.775,64.120,24.016;all P＜0.01).The leading cause of endoscopy examination in minimal change group was abdominal discomfort,which accounted for 49.0％(99/202).The leading causes of endoscopy examination in LA A group and LA-B group were esophageal symptoms,which accounted for 52.8％ (93/176) and 61.1％ (22/36).Conclusions The diagnostic rate of GERD in patients of minimal change group is low and the clinical symptoms are not typical,which is insufficient for diagnosis of GERD and needed further investigation.

BACKGROUND/AIMS: DA-9701 (Motilitone) is a new prokinetic agent formulated with Corydalis Tuber and Pharbitis Seed. We assessed the efficacy of DA-9701 in symptomatic patients with minimal change esophagitis. METHODS: Patients with minimal change esophagitis presenting with reflux or dyspeptic symptoms were randomly assigned to receive either DA-9701 30 mg or placebo t.i.d. (means 3 times a day). After 4 weeks of treatment, the primary efficacy end point determined by changes of the Nepean dyspepsia index questionnaire-Korean version (NDI-K) symptom scores, was analyzed. RESULTS: Forty-two and 39 patients were assigned to the treatment and control groups, respectively. After 4 weeks, NDI-K symptom scores were reduced from 35.4 to 13.5 (P < 0.001) and from 43.0 to 27.7 (P < 0.001) in the treatment and the control groups, respectively. However, changes in the symptom scores did not differ between the 2 groups (P = 0.741). Although the quality of life scores were significantly improved after 4 weeks in both groups, changes in the quality of life score between the baseline value and that at 4 weeks did not differ between the 2 groups. The reflux symptom score was significantly improved in the treatment group compared to the placebo group in patients aged 65 years or older (P = 0.035). CONCLUSIONS: Although NDI-K symptom scores and quality of life scores were improved after 4 weeks of treatment compared with baseline values in patients with minimal change esophagitis, DA-9701 did not improve the symptom scores or quality of life scores compared with the placebo.

La esofagitis de reflujo, es una entidad clínica que forma parte de la enfermedad de reflujo gastroesofágico (ERGE). A pesar que la endoscopia, tiene una excelente especificidad en 90% - 95%, su sensibilidad es sólo del 50%. Más del 50% de los pacientes con síntomas de ERGE han sido diagnosticados como enfermedad por reflujo no erosivo, (ERNE). El análisis más cuidadoso de los estudios publicados, reporta que la mayoría de los pacientes con ERNE tenían pequeños cambios en la mucosa del esófago distal, específicamente proximal a la línea Z; introduciéndose con estos hallazgos el término de esofagitis de cambios mínimos. Pero también cambios característicos de los bucles capilares papilares intraepiteliales (BCPIE) han sido demostrados, en pacientes con esofagitis de cambios mínimos por ERGE. Evaluar y comparar en pacientes con el diagnóstico de ERNE y en pacientes controles, la alteración morfológica de BCPIE en el esófago distal, con la intención de diagnosticar esofagitis de cambios mínimos, utilizando endoscopios de alta resolución con magnificación, cromoscopia electrónica e imagen espectral FICE. Estudio de corte transversal, prospectivo, con un muestreo no probabilístico, de tipo intencional y grupo control, realizado con pacientes que asistieron a la consulta ambulatoria del servicio de Gastroenterología del Hospital Universitario de Caracas y de la Clínica El Ávila, desde mayo de 2007 a noviembre de 2011. De 156 pacientes con diagnóstico de ERNE y 100 pacientes de grupo control. Grupo control: 100 pacientes, 3 pacientes con BCPIE tipo II (1%). Grupo ERNE 156 pacientes, 5 tenían un patrón: Tipo I considerado normal y 151 tenían un patrón de los BCPIE alterado: 146 con patrón de BCPIE Tipo II (96,68%), sensibilidad 97%, especificidad 97%; 5 (3,31%), tenían un patrón de BCPIE Tipo III sensibilidad 5% y especificidad 0%. Los cambios anatómicos encontrados en los BCPIE de la mucosa del esófago, cuando se hace una endoscopia digestiva...
Reflux esophagitis is a clinical entity that is part of Gastroesophageal Reflux Disease (GERD). Although endoscopy has an excellent specificity of 90% -95%, its sensitivity is only 50%. Over 50% of patients with symptoms of GERD have been diagnosed as non-erosive reflux disease (NERD). More careful analysis of the published studies reported that most NERD patients had minor changes in the distal esophageal mucosa, specifically proximal to the Z line; introducing with these findings the term of Minimal Change Esophagitis. Also changes characteristic of Intra Papillary Epithelial Capillary Loops (BCPIE) have been demonstrated in patients with Minimal Change Esophagitis by GERD. To evaluate and compare patients with the diagnosis of NERD and controls, BCPIE morphological alteration in the distal esophagus, with the intention of diagnosing minimal change esophagitis, using high-resolution magnification endoscopes, electronic and spectral imaging chromoscopy FICE. Prospective, cross-sectional study with a non-probability sampling, intentional kind and control group, of patients attending the outpatient clinic of the Department of Gastroenterology, University Hospital of Caracas and of Avila Clinic, from May 2007 to November 2011. Of 156 patients diagnosed with NERD and 100 patients in the control group. Control group: 100 patients, 3 patients with type II BCPIE (1%). NERD group 156 patients, 5 had a pattern: Type I considered normal and 151 had a pattern of altered BCPIE: 146 BCPIE with a Type II pattern (96, 68%), sensitivity 97%, specificity 97%; 5 (3, 31%), had BCPIE with a Type III pattern Sensitivity 5% and Specificity 0%. The anatomical changes found in BCPIE at the esophageal mucosa, when an endoscopy is performed in patients with GERD, allow the diagnosis of Minimal Change Esophagitis. The BCPIE type II pattern is the most frequently found in Minimal Change Esophagitis. The indication of Endoscopy with high definition magnification....
