Inverse correlation between gastroesophageal reflux disease and atrophic gastritis assessed by endoscopy and serology

BACKGROUND Helicobacter pylori(H.pylori)infection is known to prevent the occurrence of gastroesophageal reflux disease(GERD)by inducing gastric mucosal atrophy.However,little is known about the relationship between atrophic gastritis(AG)and GERD.AIM To confirm the inverse correlation between AG and the occurrence and severity of GERD.METHODS Individuals receiving health checkups who underwent upper gastrointestinal endoscopy at Seoul National University Healthcare System Gangnam Center were included.The grade of reflux esophagitis was evaluated according to the Los Angeles classification.Endoscopic AG(EAG)was categorized into six grades.Serologic AG(SAG)was defined as pepsinogen I≤70 ng/m L and pepsinogen I/II ratio≤3.0.The association between the extent of EAG and SAG and the occurrence and severity of GERD was evaluated using multivariate logistic regression analysis.RESULTS In total,4684 individuals with GERD were compared with 21901 healthy controls.In multivariate logistic regression analysis,advanced age,male sex,body mass index>23 kg/m2,presence of metabolic syndrome,current smoking,and alcohol consumption were associated with an increased risk of GERD.Seropositivity for H.pylori immunoglobulin G antibodies was associated with a decreased risk of GERD.There was an inverse correlation between the extent of EAG and occurrence of GERD:Odds ratio(OR),1.01[95%confidence interval(CI):0.90-1.14]in C1,0.87(0.78-0.97)in C2,0.71(0.62-0.80)in C3,0.52(0.44-0.61)in O1,0.37(0.29-0.48)in O2,and 0.28(0.18-0.43)in O3.Additionally,the extent of EAG showed an inverse correlation with the severity of GERD.The presence of SAG was correlated with a reduced risk of GERD(OR=0.49,95%CI:0.28-0.87,P=0.014).CONCLUSION The extent of EAG and SAG exhibited strong inverse relationships with the occurrence and severity of GERD.AG followed by H.pylori infection may be independently protect against GERD.

Surgical approach after failed enteryx injection for GERD.

OBJECTIVE: We report on 3 patients who underwent laparoscopic antireflux procedures for persistent symptoms of GERD after biopolymer injection. METHODS: Experienced laparoscopic surgeons completed all 3 procedures laparoscopically. In 2 patients, there was an extramural extravasation of the polymer outside and adherent to the esophageal wall. In these patients, a partial posterior fundoplication was used. The third patient, who had the polymer material deposits removed preoperatively by endoscopic mucosal resection, underwent a Nissen fundoplication. RESULTS: Postoperative recovery was uneventful in all cases. At follow-up of 6 to 12 months, all patients were symptom free, off medical therapy, and experiencing no dysphagia. CONCLUSION: Surgical therapy for patients after failed biopolymer injection is safe and effective. The choice of surgery may depend on whether the polymer mass can be removed preoperatively.

Conversion of laparoscopic sleeve gastrectomy to Roux-en-Y gastric bypass: patterns predicting persistent symptoms after revision

BackgroundLaparoscopic sleeve gastrectomy (LSG) is the most common bariatric operation performed. However, it is not without its drawbacks and patients may develop gastroesophageal reflux (GERD) after LSG. There are limited data available to guide treatment choice for patients suffering these sequelae.ObjectiveThis study was undertaken to evaluate the success of conversion to Roux-en-Y gastric bypass (RYGB) in treating GERD symptoms after LSG.SettingSingle bariatric center, United States.MethodsAnalysis of a prospectively maintained clinical database was performed. Outcomes studied included heartburn-related quality of life score (GERD-HRQL), anti-secretory usage, and body mass index (BMI).ResultsA total of 54 patients met inclusion criteria during the review period. Of these, 41 patients (76%) underwent conversion for indication including GERD. Mean BMI at conversion was 33.8 ± 5.61 and was found to be significantly reduced at 12 months after conversion (n = 26; 63%; P < .001) and at long-term follow-up (n = 37; 90%) (P ≤ .001; mean follow-up period: 33.3 mo). Mean GERD-HRQL at time of conversion was 31.5 ± 11.4. Conversion to RYGB produced a significant reduction of HRQL at 6 months after conversion (n = 30; 73%) (mean: 5.6, P < .001) and long-term follow-up (n = 38; 93%) (mean: 7.3, P < .001. mean follow-up period: 15.1 mo). Prior to conversion, 32 patients (78%) required antisecretory therapy for GERD and after conversion, 12 of these patients (38%) required antisecretory therapy (P < .001). These 12 patients were found to exhibit a significantly (P = .005) smaller decrease in GERD-HRQL after revision compared with their peers who were liberated from antisecretory therapy. Preoperative symptoms were compared between these 2 groups. Delayed onset of GERD symptoms after LSG (>3 mo) was found to be a significant risk factor for continued antisecretory dependence after conversion to RYGB.ConclusionConversion of LSG to RYGB quantitatively reduces GERD symptoms, and results in a modest but significant amount of weight loss. While there was a significant improvement in HRQL after revision, a subgroup of patients continued to be antisecretory-dependent and showed a limited improvement in HRQL. This limited response was predicted by a gradual onset of GERD symptoms prior to revision. An interval of 3 months or greater between LSG and onset of symptoms was found to be a significant risk factor for limited response to conversion.     

氧化应激在反流物所致食管粘膜损伤中的作用

目的：探讨氧化应激在反流物所致食管粘膜损伤中的作用。方法：60只雄性SD大鼠随机分为两组,模型组行食管十二指肠吻合术制备胃十二指肠混合反流性食管炎模型；对照组行假手术。术后4周取食管，按炎症轻重将模型组分为A（1级）、B（2级）、C（3级）、D（4级）4组。测定不同等级食管炎组织中MDA含量及SOD、GSH-PX的活力。结果：组织中MDA的含量，对照组与模型各组相比，P<0.01，有显著差异；模型各组之间两两比较，除A、B两组外，其余各组之间均有显著差异，P<0.01。组织中SOD活力，对照组与模型B、C、D各组相比，均有显著差异，P<0.01；模型各组比较，除B、C两组外，其余各组间均有显著差异，P<0.01。组织中GSH-PX的活力与SOD结果相似。Logistic回归分析显示：只有MDA进入回归方程，P<0.01。结论：氧化应激在反流物所致食管粘膜损伤中可能起重要作用。
