METHODS: In this prospective questionnaire study, 150 consecutive type 2 diabetic patients attending the endocrine clinic were enrolled. A junior physician helped the patients to understand the questions. Patients were asked about the presence of five most frequent symptoms of GERD that included heartburn (at least 1/wk), regurgitation, chest pain, hoarseness of voice and chronic cough. Patients with past medical history of angina, COPD, asthma, cough due to ACEI or preexisting GERD prior to onset of diabetes and apparent psychiatric disorders were excluded from the survey. We further divided the patients into two groups based on presence or absence of peripheral neuropathy. Out of 150 patients, 46 had neuropathy, whereas 104 patients did not have neuropathy. Data are expressed as mean ± SD, and number of patients in each category and percentage of total patients in that group. Normal distributions between groups were compared with Student t test and the prevalence rates between groups were compared with Chi-square tests for significance. RESULTS: The average duration of diabetes were 12 ± 9.2 years and the average HbAlc level of this group was 7.7% ± 2.0%. The mean weight and BMI were 198 ± 54 Ibs. and 32 ± 7.2 kg/m^2. Forty percent (61/150) patients reported having at least one of the symptoms of GERD and thirty percent (45/150) reported having heartburn at least once a week. The prevalence of GERD symptoms is higher in patients with neuropathy than patients without neuropathy (58.7% vs 32.7%, P 〈 0.01). The prevalence of heartburn, chest pain and chronic cough are also higher in patients with neuropathy than in patients without neuropathy (43.5% vs 24%; 10.9% vs 4.8% and 17.8% vs 6.7% respectively, P 〈 0.05). CONCLUSION: The prevalence of GERD symptoms in type 2 DM is higher than in the general population. Our data suggest that DM neuropathy may be an important associated factor for developing GERD symptoms.展开更多

Biopsies showed prominent intestinal metaplasia of Barrett's type without dysplasia, chronic inflammation and multiple aggregates of large cells within the mucosal lamina propria, some with spindle shaped nuclei. Immunohistochemistry stains for keratins AE-1/ AE-3 were negative, while S-100 and NSE were positive. This, together with routine stains, was diagnostic for mucosal ganglioneuromatosis. The background of chronic inflammation with intestinal type metaplasia was consistent with long-term reflux esophagitis. No evidence of achalasia was seen. Biopsies of gastric antrum and fundus were unremarkable, without ganglioneural proliferation. Colonoscopy was unremarkable. No genetic syndromes were identified in the patient including familial adenomatous polyposis and multiple endocrine neoplasia type Ⅱ b (MEN Ⅱ b). Iansoprazole (Prevacid) was started by oral administration each day with partial relief of symptoms. Subsequent esophagogastroscopy repeated at 4 mo showed normal appearing EG junction. Esophageal manometry revealed a mild nonspecific lower esophageal motility disorder. Mild motor dysfunction is seen with gastro-esophageal reflux disease (GERD) and we feel that the demonstration of localized ganglioneuromatosis was not likely related etiologically. In the absence of findings that might suggest neural hypertrophy, such as achalasia, the nodular mucosal irregularity seen with this instance of ganglioneuromatosis may, however, have exacerbated the patient's reflux.展开更多

METHODS: Twenty mongrel dogs were used for experiments. Group 1 (n =5) served as a salinetreated control, while in group 2 (n = 5) the esophagus was exposed to bile for 3 h. In group 3 (n =5) the animals were pretreated with 7-nitroindazole to inhibit the neuronal isoform of nitric oxide synthase. In group 4 (n = 5) phosphatidylcholine solution (50 rng/kg) was administered iv before the biliary challenge. Mucosal microcirculation was observed by intravital videomicroscopy. Myeloperoxidase and nitric oxide synthase activities, the degrees of mast cell degranulation and mucosal damage were evaluated via tissue biopsies. RESULTS: Exposure to bile evoked significant mast cell degranulation and leukocyte accumulation. The red blood cell velocity and the diameter of the postcapillary venules increased significantly. The tissue ATP content and constitutive nitric oxide synthase activity decreased, while the inducible nitric oxide synthase activity increased significantly as compared to the control values. 7-nitroindazole treatment significantly exacerbated the mucosal mast cell degranulation and tissue damage. Tn contrast, phosphatidylcholine pretreatment prevented the bile-induced ATP depletion, the inducible nitric oxide synthase and myeloperoxidase activity and the mast cell degranulation increased. CONCLUSION: The neuronal nitric oxide synthasemast cell axis plays an important role in the esophageal mucosal defense system. Systemic phosphatidylcholine pretreatment affords effective protection through ameliorating the bile-induced ATP depletion and secondary inflammatory reaction.展开更多

METHODS: Patients with reflux symptoms were enrolled and stratified to NERD and ERD after endoscopy (LA classification). Patients with ERD presenting with dyspepsia were included. Patients on proton pump inhibitors (PPI) or H2 receptor antagonists before endoscopy were excluded. Demographic data, Helicobacter pylori(H pylori) status and presence of minor psychiatric morbidity (based on General Health Questionnaire-28) were analyzed. RESULTS: Among 690 patients screened, 533 were eligible for analysis (male to female ratio: 3:2; Chinese: 75.4%; Malay: 9.8%; Indian: 14.8%). Clinical spectrum of GERD: N: 40.5%; A: 46%; B: 9.2%; C: 2.1%; D: 0.6%; Barrett's esophagus: 1.7%. Compared to patients with NERD, patients with ERD were significantly older (45 vs 39.4 years), more likely to be male (64.4% vs 53.7%), tended to smoke (19.6% vs 9.7%), less likely to have minor psychiatric morbidity (26.4 vs 46.7%) and were more likely to respond to PPI (79.7 vs 66.8%). There was also a trend towards a higher BMI (24.5 vs 23.5). Race, alcohol consumption and H pylori status were not significant. On multivariate analysis, age and presence of minor psychiatric morbidity remained with significant differences. CONCLUSION: The majority of patients who have typical symptoms of GERD have NERD or mild erosive reflux disease. Compared to patients with erosive reflux disease, patients with NERD were younger and had a higher prevalence of minor psychiatric morbidity.展开更多

METHODS From January 2003 to April 2009, 237 patients were selected to undergo resection of esophageal squamous carcinoma via posteroexternal incision of the left chest plus gastroesophageal anastomosis at the left neck incision. The 237 cases were divided into 2 groups: 115 of the total cases were in group A (the study group), cases of resections with neck RLN exposure. Of the patients in this group, 64 were male and 51 female, with a mean age of 49 ranging from 31 to 73 years. Another 122 cases were in group B (the control group), cases of resections without neck RLN exposure. In this group, 51 of the patients were male and 71 female, with a mean age of 45 ranging from 33 to 75 years. In the 2 groups, there were 9 cases in total with symptoms induced by RLN injury. RESULTS Hoarseness, choking cough when drinking, and difficult expectoration were found in 1 of the cases (1/115) in group A (0.087%), while there were 8 cases (8/122) presenting with these symptoms in group B (6.5%). There is statistical signi.cance in the di.erences of RLN injury between the 2 groups (P 〈 0.05). CONCLUSION Analysis of study cases of esophageal carcinoma resection with left-neck esophagogastric anastomosis in the 2 groups indicated that the exposure of the RLN in group A resulted in an obviously lower rate of neck RLN injury after the surgery, compared to group B, where the RLN was not exposed. Exposure can lead to the avoidance of complications induced by RLN injury, such as dysarthria and choking cough when eating. As a result, satisfactory expectoration, which would diminish the incidence of pulmonary complications, can be reached allowing the patients to recover as early as possible. The results of our study suggest that the exposure of the RLN during the left -neck esophagogastric anastomosis has signi.cant clinical value, and that this approach can be recommended with con.dence.展开更多
