Numerous studies have investigated utility of esophageal intraluminal baseline impedance levels (BILs) in gastroesophageal reflux disease (GERD). However, effect of BILs in refractory GERD (RGERD) has not been well investigated. The aim of this study is to evaluate role of BILs in RGERD patients. Total 62 subjects with refractory gastroesophageal reflux symptoms underwent 24-hour impedance-pH m...

Sixty one patients with primary vesicoureteric reflux were treated by endoscopic injection of Mentor Polytef paste. Seventy six of the 94 treated ureters showed complete disappearance of vesicoureteric reflux after one injection. Eight refluxing ureters required a second injection, one required a third, and one a fourth. Six ureters showed improvement in the grade of reflux after the first inje...

BACKGROUND The observation of cecoileal reflux to barium enema is not rare; however, its causes and consequences have not been widely investigated. Considering that ileocecal junction exerts a function as barrier to invasion of bacteria from colon to small bowel, it seems interesting to study the intestinal microflora in subjects carrying cecoileal reflux. AIMS This study aims at evaluating t...

Although duodenogastric reflux is a physiological event, excessive reflux may be a pathogenetic factor in several diseases of the foregut, including cancer. Long term profound duodenogastric reflux produces pancreatic and gastric tumours in rats. The trophic effect of surgically induced duodenogastric reflux on the pancreas was investigated and the mechanisms involved were examined. Rats with p...

BACKGROUND The relationship between Helicobacter pylori and reflux oesophagitis remains controversial. AIMS To evaluate the relationship between H pylori and reflux oesophagitis in a large number of Japanese subjects. SUBJECTS A total of 5732 consecutive Japanese subjects during a health screening were enrolled. METHODS Gastrointestinal endoscopy was performed on all subjects. We simultan...

Objectives: To investigate clinicopathologic findings and gallbladder (GB) function in patients with endoscopic bile reflux at outpatients clinic. Methods: We classified endoscopic bile reflux into two groups by bile reflux index (BRI). Those who scored above 14 were the BRI (+) group, and those below 14 were the BRI (-) group. We analyzed clinical characteristics, endoscopic findings including...

BACKGROUND & AIMS Gastroesophageal reflux disease (GERD) is strongly associated with sleep disturbances. Proton pump inhibitor (PPI) therapy improves subjective but not objective sleep parameters in patients with GERD. This study aimed to investigate the association between GERD and sleep, and the effect of PPI on sleep by using a rat model of chronic acid reflux esophagitis. METHODS Acid ref...

The aim of this study was the separate measurement of reflux of food and acid into the oesophagus in 37 healthy, ambulant subjects. This was performed by radiolabelling the food and monitoring its reflux with a small directional gamma detector, which was placed externally over the oesophagus, and connected to an ambulatory data recorder. The pH was measured with a conventional oesophageal pH el...

PURPOSE OF THE STUDY Endoscopy Normal Reflux Disease (ENRD) is a common presentation of reflux disease. These patients are symptomatic but do not have abnormal endoscopy findings. They may have pathological intraesophageal reflux. Lifestyle modifications are the mainstay of management of these patients. Posture plays an important role in their management. It was felt that exact quantification o...

BACKGROUND/AIMS In patients with gastroesophageal reflux disease, persistent symptoms on proton pump inhibitor (PPI) therapy may be due to residual acid or non-acid reflux. Combined impedance-pH has been suggested to be superior to pH alone in the management of refractory patients to PPI. The utility of implementation of this technique in every day clinical practice is still unknown. The aim of...
