Prospective analysis of the morphological changes occurring in the oesophagus of male Sprague-Dawley rats after oesophagojejunostomy was studied. Following surgery 70 rats were randomised into 7 groups of 10 animals. The groups were sacrificed at 4 weekly intervals up to 28 weeks. Terminal pH measurements were mode at the level of the oesophagojejunal anostamosis, and the oesophagi examined. Reflux of jejunal contents into the lower oesophagus of rats induces a series of morphological changes similar to those observed in human duodenogastro-oesophageal reflux disease. Tumour initiation and progression seems to occur in the absence of an acidic stimulus.

    Background Redo fundoplication has acceptable outcomes in patients with failed previous fundoplications. However, a subset of patients require Roux-en-Y (RNY) reconstruction for symptom relief. Aim The aim of this study was to demonstrate safety and efficacy of RNY reconstruction for failed...

    Background: Nocturnal reflux is important in the pathogenesis of esophagitis. The relationship between reflux and sleep is poorly understood, although data support both paradigms of nocturnal reflux causing arousal and nocturnal arousal allowing reflux. Furthermore, the effect of fundoplication...

    Intuitively, more severe acid reflux causes more severe symptoms. This study was undertaken to correlate preoperative DeMeester scores with symptoms before and after laparoscopic Nissen fundoplication. Before fundoplication, all patients with gastroesophageal reflux disease underwent 24 to 48...

    Duodenogastric reflux (DGR) is a common sequel of subtotal esophagectomy and gastric pull-up, and it may contribute to mucosal changes of both the gastric conduit and the esophageal remnant. This study investigated the effect of the route of reconstruction on the DGR. 24-hour ambulatory...

    From May 1996 to April 2002, 48 laparoscopic fundoplications were performed after failure of medical treatment in 47 neurologically impaired infants and children affected by gastroesophageal reflux.

    The reliability of Nissen fundoplication for the successful treatment of laryngopharyngeal reflux (LPR) symptoms remains in question. The purpose of this study was to assess the effect that antireflux surgery has on a variety of LPR symptoms as well as the patient's perceived success of surgical...
