Gas Bloat Syndrome after Nissen Fundoplication: Association with Anatomical Failure and Revisional Operation.

A multivariable model stepwise selection procedure was constructed on the basis of these findings, which found that only BMI showed a trend toward association with failure (odds ratio 2.46 [95% CI 0.88 to 6.92], p = 0.088).

In a prospective study, vomiting was significantly more common among patients who experienced long-term failure compared with those who did not (12% vs 4%, p = 0.01), and retching showed a strong trend toward association (32% vs 18%, p = 0.15). 19 Wakeman and Hunter similarly reported that postoperative retching was a key predictor of early disruption. 20 , 21 Biomechanical studies help explain this vulnerability, showing that the bursting pressure of a fundoplication is approximately 250 mmHg, y
