Dysphagia after laparoscopic Nissen fundoplication

Objective. To investigate the frequency and severity of dysphagia during the first 8 weeks after laparoscopic Nissen fundoplication for gastro-oesophageal reflux disease. So far, there have been no studies reporting data on day-to-day occurrence of dysphagia after laparoscopic fundoplication in a consecutive series of patients. This may explain why the frequency of dysphagia varies greatly in the literature (4-100%). Material and methods. Forty consecutive patients, undergoing elective laparoscopic Nissen fundoplication, completed a standard dysphagia registration diary each day during the first 8 weeks after surgery. Patients who preoperatively had suffered from dysphagia were excluded. Thus, none of the patients had dysphagia in the 2-month period before surgery. Ten patients undergoing elective cholecystectomy served as controls. Data were quantified, and a score value of 4 or more was considered bothersome. Results. Thirty-seven patients (93%) experienced some degree of dysphagia during the observation period. Sixteen patients (44%) had at least one day with annoying dysphagia. The dysphagia started 1-2 days after surgery, was most prominent during the first few weeks, and subsided in nearly all cases after 5-6 weeks. Two patients with persistent dysphagia were treated once with balloon dilatation. None of the patients in the control group had dysphagia. Conclusions. Nearly all patients experience some degree of dysphagia after laparoscopic Nissen fundoplication, and in nearly half of the patients it is considered annoying. However, even severe dysphagia usually disappears within 5-6 weeks. These results suggest a conservative attitude for the first 1-2 months after surgery. The data may also serve as a background for preoperative information to the patients.
