Figure 2 Quality of life at 24 mo follow-up. Postoperative Qol (as measured by the SF-36 questionnaire) in patients with a partial anterior fundoplication and with a total fundoplication (P > 0.05; unpaired t-test).

Figure 3 Postoperative oesophageal manometry. Neo-sphinteric median resting pressure in patients with a Dor and with a Nissen-Rossetti fundoplication (P < 0.0001; Mann-Whitney U-test).
