Anterior 90° partial vs Nissen fundoplication--5 year follow-up of a single-centre randomised trial

Nissen fundoplication can be followed by side effects, and this has driven modifications, including partial fundoplications. We previously reported early outcomes from a randomised trial of Nissen vs anterior 90° partial fundoplication. This paper reports 5-year follow-up outcomes to determine whether anterior 90° fundoplication achieves a satisfactory longer-term outcome.

From February 1999 to August 2003, 79 patients were randomised to Nissen vs anterior 90° fundoplication. Patients were followed yearly using a standardized clinical questionnaire which included symptom scores to assess heartburn, dysphagia, other post-fundoplication side effects and overall satisfaction with the outcome. Five-year clinical outcomes were analysed.

Seventy-four patients were available for follow-up at 5 years. There were no significant differences for heartburn or satisfaction, although more patients used antisecretory medication after anterior 90° fundoplication (29.7 vs 8.1 %). Dysphagia was greater after Nissen fundoplication when measured by an analogue score for solid food and a composite dysphagia score. Symptoms of bloating were more common following Nissen fundoplication (80.0 vs 32.4 %), and less patients could eat a normal diet (78.4 vs 94.6 %). Re-operation was undertaken in four patients after Nissen fundoplication (dysphagia, three; hiatus hernia, one) vs three after anterior 90° fundoplication (recurrent reflux, three).

At 5 years, anterior 90° partial fundoplication was associated with less side effects, offset by greater use of antisecretory medication. Reflux symptoms and overall satisfaction were similar to Nissen fundoplication. Laparoscopic anterior 90° partial fundoplication is an effective treatment for gastro-esophageal reflux.
