[Assessment of quality of life after antireflux surgery]

To assess the quality of life (QoL) of patients operated for gastroesophageal reflux disease (GERD).

This prospective study included 82 consecutive patients submitted to antireflux surgery between October 1998 and January 1999. A new questionnaire was used to assess their QoL: the Gastrointestinal Quality of Life Index (GIQLI) that includes 36 items concerning 5 dimensions: symptoms, vitality, emotions, social relations and medical treatment. The series consisted of 44 men and 38 women with a mean age of 47 years (range: 18-78). QoL was assessed before and 6 months after surgery; the follow-up rate was 94% (77/82). The pre- and postoperative GIQLI scores of the study group and the GIQLY score of a control group of 110 healthy patients were compared.

Before surgery, the GIQLI score (90 +/- 23) was greatly impaired compared to the score (123 +/- 13) observed in the control group (p < 0.001). After surgery, the GIQLI score (110 +/- 23) increased significantly (p < 0.001), but remained statistically lower than the score of the control group (p < 0.001). The postoperative score recorded in the symptoms dimension was lower than the control group score: 55 +/- 11 versus 66 +/- 6 (p < 0.001), while no significant difference was observed in the other 4 dimensions. Univariate statistical analysis revealed that the postoperative GIQLI score (y) was correlated with the preoperative GIQLI score (x) according to the formula: y = 0.43 x + 71 (p < 0.001) and the sex of the patients, as the postoperative GIQLI score was higher in male patients (115 +/- 19) than in female patients (103 +/- 23) (p < 0.02).

The QoL of the patients was greatly improved after antireflux surgery, but remained lower than that of a control group of healthy subjects. Better patient selection should improve the results. In our series, male patients or patients with a high preoperative GIQLI score were the best candidates for antireflux surgery.
