[Laparoscopic Nissen fundoplication: results and prognostic factors].

INTRODUCTION: Laparoscopic Nissen fundoplication is the technique of choice in the surgical treatment of gastroesophageal reflux disease.

AIMS: To review the cases of laparoscopic Nissen fundoplication carried out at our hospital and to analyze the prognostic factors that influenced surgical outcome.

MATERIAL AND METHODS: A total of 226 patients that underwent laparoscopic Nissen fundoplication within the time frame of 1996 to 2010 were retrospectively reviewed. Surgical results and prognostic factors were evaluated in 182 patients that had a follow-up longer than one year.

RESULTS: The Nissen-Rossetti technique was carried out in 219 patients, without short gastric vessel division, and the "floppy"-Nissen technique was performed on seven patients. Intraoperative complication rate was 3.1%, conversion rate was 6.6%, and postoperative complication rate was 4%. Mortality was 0. After surgery, 19% of patients presented with dysphagia that was persistent in only 3.5%. Of the 182 patients with a follow-up longer than one year, 166 (91.2%) were satisfied with the surgical results. In the univariate analysis, esophagitis (OR=0.59) was a protective factor, while a DeMeester score >50 (OR=1.97) and medical treatment resistance (OR=1.75) were risk factors. In the multivariate analysis a DeMeester score >50 (OR=4.24) was the only independent prognostic factor associated with poor outcome.

CONCLUSIONS: Our results with laparoscopic Nissen fundoplication are comparable to those found in the medical literature, with a high degree of patient satisfaction. Esophagitis is associated with good outcome, while massive reflux and medical treatment resistance are negative prognostic factors.
