Symptoms suggestive of gastro-oesophageal reflux disease are very common. The aim of the study was to assess the prevalence of these symptoms and factors influencing them in an unselected adult population. A questionnaire was mailed to a random sample of 2500 people aged > or = 20 years. The questions concerned heartburn, regurgitation, dysphagia, chest and upper abdominal pain, as well as medication and medical consultations for these symptoms. Of the 1700 (68%) responders, 9% had experienced heartburn on the day of response and 15%, 21% and 27% during the preceding week, month and year, respectively. The corresponding figures for regurgitation were 5, 15, 29 and 45%. During the past year 43% of the study group had had no such symptoms. Age, overweight, pregnancy and cigarette smoking significantly influenced the prevalence of symptoms. Using daily heartburn and/or regurgitation as dominant indicators 10.3% (95% CI 12-11.7) of the responders had gastro-oesophageal reflux disease. Medication (most commonly antacids) was used by only 16% of the symptomatic people, and only 5.5% had sought medical advice for symptoms during the past year. Thus, despite commonness of symptoms suggestive of gastro-oesophageal reflux disease only a minority of the individuals suffering from such symptoms use medication or have medical consultation.
Fundic mobilization did not give any apparent advantage regarding postoperative adverse effects. Instead, it was associated with a higher rate of recurrent hiatal hernia.
Fifty patients reoperated for failed Nissen fundoplication are presented; 29 patients (group 2) were operated between 1983 and 1988 while 21 patients (group 1) were operated before 1983. In group 1, the "slipped Nissen" had been the most frequent cause of reoperation (48%). In group 2, the most frequent causes for the unsuccessful operation were: (1) partial or total disruption of the fundic wrap (62%), (2) slipping of the fundoplication, giving rise to the telescope phenomenon (21%), and (3) creation of a fundoplication which was too low (10%). Refundoplication was performed in cases where the dissection of the previously formed fundic wrap was possible (42/50 = 84%). In group 1, three patients were treated by resection of the cardia, one by an Angelchik prosthesis and one by a distal gastric resection with Roux-en-Y diversion. In group 2, fundectomy was performed in one patient; in another, an Angelchik device was inserted, and in a third patient, fundoplication and proximal gastric vagotomy were performed. The results were excellent or good in 66% of patients in group 1 and in 76% of group 2. Operative mortality was 2% and morbidity, 4%. In conclusion, repeat fundoplication is recommended when reestablishment of the fundic region anatomy is possible during dissection. The operation can usually be performed through an abdominal route. Meticulous preoperative evaluation of the patients including 24-hour pH measurement and manometry is necessary. Good results of refundoplication should be expected in 66%-76% of patients with recurrent disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
