Abstract

Book reviews in this article:

Collis-Nissen gastroplasty fundoplication is a widely accepted operation for patients with gastro-oesophageal reflux disease complicated by oesophageal shortening. Assessment of this operation by 24 h oesophageal pH monitoring has not previously been reported. Our aim was to correlate clinical and endoscopic results with 24 h pH studies. Twenty-nine patients had a gastroplasty fundoplication, as a result of which twenty-five (86%) had an excellent clinical result, 2 (7%) had a good result and 2 (7%) had a poor result. The two poor results were in patients who had previously undergone anti-reflux surgery. All 29 patients had pre-operative pH monitoring. Twenty-three patients had postoperative pH studies. Oesophageal acidification times were normal postoperatively in 16 of 23 patients however, 7 still had an abnormal study. One of the two patients with a poor clinical result was studied and persistent severe oesophageal acidification was demonstrated. The remaining 6 patients with abnormal studies were asymptomatic. Five of the 6 asymptomatic patients also had a normal oesophagogastroscopy with no macroscopic oesophagitis. We conclude that 24 h pH monitoring after the Collis-Nissen operation should only be performed to assess clinically and endoscopically poor results.
