Significant weight loss after laparoscopic Nissen fundoplication

Laparoscopic Nissen fundoplication (LNF) has evolved as a gold standard in antireflux surgery. However, the association between body weight and gastroesophageal reflux disease (GERD) is still unclear, and no data are available concerning the effect of fundoplication on body weight. We present the first report elucidating the impact of LNF on body weight in GERD patients with special emphasis on patients' quality of life.

From July 2000 to March 2003, LNF was carried out in 213 patients (85 women and 128 men) after thorough preoperative examination including clinical interview with standardized assessment of symptoms and quality of life (QoL), endosocopy, barium swallow, 24-h pH-metry, and manometry. Follow-up investigations were performed 3 and 12 months after LNF obtainable from 209 patients (98.1%) and 154 patients (72.3%), respectively.

The mean body mass index (BMI) decreased significantly after LNF (27.6 +/- 5.6 kg/m(2) before LNF vs 26.0 +/- 3.8 kg/m(2) after LNF, p < 0.001). Twelve months after LNF, neither a tendency toward a renewed increase nor a further decrease in BMI was observable. The average body weight loss was 3.9 kg. BMI reduction was higher in women than in men (p < 0.002), and obese patients lost more weight than lean patients (p < 0.001). There was no association between BMI reduction and dysphagia. Plasma cholesterol and triglyceride levels did not change after LNF. The mean general score of the Gastrointestinal Quality of Life Index markedly improved (90.1 +/- 21.3 before LNF vs 118.0 +/- 16.2 after LNF, p < 0.01), as did the GERD-Health Related Quality of Life Index (21.9 +/- 6.4 before LNF vs 3.5 +/- 2.7 after LNF, p < 0.001). However, there was no association between changes in BMI and QoL.

LNF leads to significant and persistent body weight loss.
