Abstract
BACKGROUND
Advocates of the Toupet partial fundoplication claim that the procedure has a lower rate of the side effects of dysphagia and gas bloat than a complete Nissen fundoplication. However, there is increasing recognition that reflux control is not always as good with the Toupet procedure as with the Nissen. Therefore, we set out to evaluate the factors contributing to success and failure in patients who underwent laparoscopic modified Toupet fundoplication (LTF).
METHODS
A total of 143 patients undergoing LTF for documented gastroesophageal reflux disease (GERD) were evaluated prospectively in regard to their outcomes over a 4-year period. All patients had preoperative esophagogastroduodenoscopy (EGD) and manometry; 24-h pH testing was used selectively. Esophageal manometry was requested of all patients 6 weeks postoperatively. Clinical follow-up was by office visit or questionnaire every 6 months after surgery; patients with significant problems were investigated further. Failure was defined as the development of recurrent reflux documented by endoscopy, 24-h pH test, or wrap disruption on barium swallow, or severe dysphagia persisting >3 months and requiring surgical revision.
RESULTS
At a mean follow-up of 30 months (range, 3-51), 21 of 143 patients failed LTF; two had dysphagia and 19 had recurrent reflux. Failure was associated with preoperative findings of a defective lower esophageal sphincter (LES) (14/21), complicated esophagitis (13/21), and failure to divide short gastric vessels (12/19) (chi-square p < 0.05). Defective esophageal body peristalsis, present in 14 patients, resulted in failure in six cases. Presence of either complicated esophagitis or a defective LES was associated with a 3-year 50% success rate, whereas presence of mild esophagitis and a normal LES was reflected in a 96% 3-year success rate.
CONCLUSION
Laparoscopic Toupet fundoplication should be reserved for milder cases of GERD, as assessed by manometry and endoscopy.
