Late results of paraoesophageal hiatus hernia repair with fundoplication

Abstract

Background: Most published reports on results of surgical treatment for paraoesophageal hiatus hernia have been based on patient questionnaires, and seldom included endoscopy or barium meal examinations. Methods: Eight pure and 14 mixed-type paraoesophageal hernias were evaluated a median of 37 (range 2-241) months after surgical repair. An antireflux procedure was done in 19 cases. Before operation all had endoscopy or barium meal (20 and 19 patients respectively); after operation 19 had endoscopy and 12 also had barium meal examination. Oesophageal 24 h pH monitoring was done in five cases before surgery, and in 11 afterwards. Results: Preoperative symptoms of reflux were reported by 18, and were often accompanied by dysphagia, postprandial vomiting or epigastric pain. Symptoms improved after operation, and 21 of the 22 patients were satisfied with the result. At follow-up examination, a recurrent hernia was found in eight of the 19 patients examined. Four of these hernias were sliding, two were mixed type and two purely paraoesophageal. Discussion: Recurrence of symptoms was associated with persistence of reflux rather than hernia recurrence. Concomitant antireflux procedure is recommended in all operations for mixed-type hiatus hernia, but it should also be considered for purely paraoesophageal hernia if reflux cannot be excluded before operation, or if retro-oesophageal dissection is needed.
