Outcome of laparoscopic Nissen fundoplication in patients with disordered preoperative peristalsis.

BACKGROUND A 360 degrees or Nissen fundoplication remains controversial in patients with disordered peristalsis, some surgeons preferring a partial wrap to minimise postoperative dysphagia. AIM To evaluate symptoms and manometric outcome in patients with disordered peristalsis after Nissen fundoplication. PATIENTS In an initial series of 345 patients studied prospectively, 31 patients who had undergone a Nissen fundoplication had disordered peristalsis. Using preoperative manometry, patients were classified as: equivocal primary peristalsis (eight patients); abnormal primary peristalsis (four patients); abnormal maximal contraction pressure (13 patients); abnormal primary peristalsis and maximal contraction pressure (six patients). METHODS Postoperatively, patients underwent a barium meal, oesophageal manometry and standardised clinical review by a blinded scientific officer. RESULTS Twenty eight (90%) patients had satisfaction scores of at least 8 out of a maximum of 10 and all would undergo surgery again. Whereas 15 (48%) patients had dysphagia scores greater than 4/10 preoperatively, only two (6%) had these scores at one year. Improved peristalsis was seen in 78% of postoperative manometric studies, and mean preoperative lower oesophageal sphincter pressure increased from 6.6 (range 0-21) mm Hg to 19 (4-50) mm Hg. CONCLUSIONS These results are similar to the overall group of 345 patients and suggest that disordered peristalsis, and possibly even absent peristalsis, is not a contraindication to Nissen fundoplication as performed in these patients.
