Laparoscopic nissen fundoplication and postoperative dysphagia - Can it be predicted?

Temporary swallowing difficulty has been reported in up to 100% of patients after laparoscopic Nissen fundoplication for gastrooesophageal reflux, but the long-term prevalence of dysphagia is not known. If reliable predictors of persistent postoperative dysphagia exist, their identification may permit tailoring of the fundoplication for specific cases at risk. Of 475 consecutive cases of laparoscopic fundoplication, 202 have undergone detailed symptom scoring at I year postoperatively. In each case, a short, 360° loose wrap was constructed over an intra-oesophageal bougie, and short gastric vessels were divided when insufficient fundal mobility was encountered. At one year postoperatively, 24% complained of grade 1 dysphagia (intermittent sensation of food sticking), 9% of grade 2 (food sticking requiring liquids to clear) and 1 patient had regular dysphagia for solids (grade 3). Gender, preoperative complaint of dysphagia, endoscopic grade of oesophagitis, oesophageal motility, lower oesophageal sphincter pressure, and division of short gastric vessels were reviewed in relation to dysphagia. Dysphagia is common after laparoscopic Nissen fundoplication, but is less prevalent than before operation. It is usually mild, intermittent and improves with time. Those with division of short gastric vessels had a reduced risk of postoperative dysphagia.
