    Fundoplication in children with gastro-oesophageal reflux disease

    JOURNAL OF PAEDIATRICS AND CHILD HEALTH, Issue 2 2002
    AW Norrashidah
    Objectives: The associations between gastro-oesophageal reflux (GOR), chronic respiratory symptoms and gastrointestinal complications have been well described. The aim of this study was to compare the characteristics of children in whom the main indication for fundoplication was respiratory disease with children who had gastrointestinal indications for surgery. Methods: A retrospective review of 79 children who underwent fundoplication between January 1995 and December 1999. Results: Forty-nine of the children (62%) had a respiratory indication for fundoplication. Children with neurological impairment tended to have a respiratory rather than a gastrointestinal indication for surgery. Congenital anomalies were present in 47%. Fundoplication in older children was more likely to be for a gastrointestinal indication. Children with neurological impairment were more likely to have a gastrostomy compared to children with normal neurological status (P < 0.01). Children with a respiratory indication were more likely to have three or more diagnostic investigations (P < 0.001). Ninety-two per cent of children with a respiratory indication and 90% with a gastrointestinal indication for fundoplication had at least one positive test for GOR (barium meal or 24-h oesophageal pH monitoring). Oesophagoscopy showed reflux oesophagitis in 46/61. Eighty-five per cent of the children had complete resolution of their symptoms after fundoplication. Conclusions: Neurological comorbidity was common in children who had surgery for gastro-oesophageal reflux disease, whether for gastrointestinal or respiratory indications. The majority of fundoplications were performed for respiratory indications. [source]

    Irritable bowel, smoking and oesophageal acid exposure: an insight into the nature of symptoms of gastro-oesophageal reflux

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 11-12 2004
    J. Zimmerman
    Summary Background :,In gastro-oesophageal reflux disease, oesophageal acid exposure correlates with symptoms but explains only a small fraction of their variance. Aims :,To elucidate the effects of irritable bowel syndrome and smoking on gastro-oesophageal reflux disease symptoms and to clarify whether they modulate the relationship between oesophageal acid exposure and symptoms. Methods :,The relationship between oesophageal acid exposure, irritable bowel syndrome (Rome I criteria), smoking status and symptoms was investigated in patients with a normal gastroscopy who underwent a 24-h oesophageal pH monitoring. Results :,Of 256 patients with gastro-oesophageal reflux disease, 16% were smokers and 50% met the criteria for irritable bowel syndrome (irritable bowel syndrome+). The extent of oesophageal acid exposure was unrelated to smoking or irritable bowel syndrome status. Oesophageal acid exposure, irritable bowel syndrome status and current smoking independently predicted symptoms. Irritable bowel syndrome and smoking modulated the effect of oesophageal acid exposure on symptoms: oesophageal acid exposure was predictive of symptoms only in non-smokers. However, irritable bowel syndrome was a significant predictor of symptoms both in smokers and in non-smokers. Smoking was associated with symptoms only in irritable bowel syndrome+, while oesophageal acid exposure was associated with symptoms irrespective of irritable bowel syndrome status. Conclusions :,In patients with non-erosive gastro-oesophageal reflux disease, smoking and irritable bowel syndrome independently predicted symptoms, without affecting the extent of oesophageal acid exposure. The relationship between oesophageal acid exposure and symptoms was affected significantly, and in opposite directions, by smoking and irritable bowel syndrome. [source]

    The effect of an empirical trial of high-dose lansoprazole on symptom response of patients with non-cardiac chest pain , a randomized, double-blind, placebo-controlled, crossover trial

    Summary Background :,Empirical trial with high-dose omeprazole has been shown to be a sensitive tool for diagnosing patients with gastro-oesophageal reflux disease-related non-cardiac chest pain. Aim :,To determine the clinical value of an empirical trial of high-dose lansoprazole in detecting patients with gastro-oesophageal reflux disease-related non-cardiac chest pain. Methods :,Patients who were referred by a cardiologist after a comprehensive evaluation, with at least three episodes per week of unexplained chest pain as the predominant symptom, were enrolled into the study. Oesophageal mucosal disease was determined by upper endoscopy followed by 24-h oesophageal pH monitoring to assess acid exposure. Patients were then randomized to either placebo or lansoprazole 60 mg am and 30 mg pm for 7 days. After a washout period of 1 week, patients crossed over to the other arm of the study for an additional 7 days. Patients completed a daily diary assessing severity and frequency of chest pain as the predominant symptom throughout the baseline treatment and washout periods. The lansoprazole empirical trial was considered diagnostic if chest pain score improved ,50% than baseline. Results :,Of the 40 patients with non-cardiac chest pain that were enrolled, 18 (45%) had erosive oesophagitis and/or abnormal pH test (gastro-oesophageal reflux disease-positive) and 22 (55%) had both tests negative (gastro-oesophageal reflux disease-negative). Of the gastro-oesophageal reflux disease-positive patients, 14 (78%) had significantly higher symptom improvement on lansoprazole than on placebo (22%) (P = 0.0143). Of the gastro-oesophageal reflux disease-negative group, two (9.1%) markedly improved on the medication and eight (36.3%) on placebo (P = 0.75). The sensitivity and specificity of the lansoprazole empirical trial was 78 and 80%, respectively. By day 2, 12 (85.7%) of the gastro-oesophageal reflux disease-related non-cardiac chest pain responders had either complete or almost complete symptom resolution. Conclusions :,The lansoprazole empirical trial is highly sensitive and specific for diagnosing gastro-oesophageal reflux disease-related non-cardiac chest pain patients. The trial enables diagnosing most of the responders within the first 2 days and thus a shorter duration of therapy may be considered in a subset of non-cardiac chest pain patients. [source]

    Dysfunction of oesophageal motility in Helicobacter pylori -infected patients with reflux oesophagitis

    Background: Helicobacter pylori infection has been suggested to be protective against gastro-oesophageal reflux disease. However, a significant proportion of patients with gastro-oesophageal reflux disease are infected by H. pylori. Aim: To study oesophageal motor function in H. pylori -infected patients with reflux oesophagitis. Methods: Patients with erosive reflux oesophagitis were recruited prospectively for stationary oesophageal manometry and 24-h ambulatory oesophageal pH monitoring. H. pylori status was determined by biopsy urease test. Non-reflux volunteers were recruited as controls. Results: Seventy-four patients with erosive oesophagitis (34 H. pylori -positive, 40 H. pylori -negative) and 48 non-reflux patient controls (22 H. pylori -positive, 26 H. pylori -negative) were recruited. There was no difference in severity of oesophagitis (median grade, 1; P=0.53) or oesophageal acid exposure (total percentage time oesophageal pH < 4, 7.6% vs. 6.8%; P=0.57) between H. pylori -positive and H. pylori -negative groups. Compared to H. pylori -negative patients, H. pylori -positive patients had significantly lower basal lower oesophageal sphincter pressure (12.2 mmHg vs. 15.3 mmHg; P=0.03) and amplitude of distal peristalsis (56.9 mmHg vs. 68.4 mmHg; P=0.03). Ineffective oesophageal motility (14% vs. 7%; P=0.02) and failed oesophageal peristalsis were also significantly more prevalent in H. pylori -positive patients. Conclusions: Among patients with a similar degree of reflux oesophagitis, H. pylori -infected patients have more severe oesophageal dysmotility and lower oesophageal sphincter dysfunction. Oesophageal motor dysfunction probably plays a dominant role in the development of gastro-oesophageal reflux disease in patients with H. pylori infection. [source]
