Abstract

Background

We compared percent excess body mass index loss (%EBMIL) and resolution of dyslipidaemia, hypertension, and type 2 diabetes mellitus in the 4 years following laparoscopic sleeve gastrectomy (LSG) between patients calibrated with a 40-French (40F) or a 50-French (50F) bougie.

Methods

We conducted a longitudinal retrospective descriptive study of routinely collected pre- and post-surgical data from 294 patients who underwent LSG at a single surgical centre (50F—n = 106, 40F—n = 185). Obesity measurements were taken prior to surgery and at regular intervals until 48 months post-surgery. Co-morbidity resolution was also assessed across the 48-month observation period. Multivariate regression modelling was used to control analyses for baseline obesity and sociodemographic variables.

Results

At 48 months post-surgery mean (±SD) %EBMIL was 60.2 ± 27.6% and 45.4 ± 38.4% for those treated with the 40F and 50F bougie, respectively. After controlling for sociodemographic variables and baseline excess weight, mean %EBMIL was 15.5% greater with a 40F bougie compared with a 50F bougie at the end of follow-up. The likelihood of dyslipidaemia resolution within 48 months post-LSG was 19.0 times greater (p = 0.006), hypertension resolution 3.6 times greater (p = 0.005) and type 2 diabetes mellitus resolution 5.2 times greater (p = 0.034) by 4 years post-surgery in patients treated with the 40F bougie compared with a 50F bougie.

Conclusion

Improved obesity reduction and resolution of dyslipidaemia, hypertension and type 2 diabetes mellitus is experienced during the 4 years following surgery by patients treated with a 40F bougie compared with the 50F. These findings remain when controlling for potential confounding clinical and sociodemographic factors.
