Summary

Background

Little is known about the effect of preoperative nutritional counseling on operative outcomes of bariatric surgery.

Aim

To identify and evaluate the effect of nutritional counseling on perioperative morbidity and postoperative weight loss.

Methods

The database of Medline was queried in May 2016. Randomized controlled trials comparing nutritional counseling of any form with standard care and providing data on perioperative morbidity or weight loss were considered. Pooled risk ratio (RR) or mean difference with 95% confidence intervals (CI) were computed.

Results

Three randomized controlled trials were identified. The RR for postoperative complications was 0.80 (95% CI 0.22–2.86) and the mean weight loss was −11.62 kg (95% CI 0.72 to −23.96). There was high evidence of heterogeneity among reports. No data on operative morbidity were available.

Conclusion

Current data are not adequately robust to support preoperative nutritional intervention as an effective modality to prevent perioperative morbidity and to achieve more optimal postoperative weight control. In the absence of opposing evidence, nutritional counseling prior to surgery may be conventionally recommended.
