Abstract

Purpose

Data regarding the associations between percent weight loss and the volume and weight of stomach resected during sleeve gastrectomy (SG) are mixed. The purpose of this study was to evaluate the effect of the size and volume of stomach removed during laparoscopic SG on percent total body weight lost (%TBWL).

Methods

An observational case series study was performed on 67 patients for 1 year after SG at a single university-affiliated, tertiary care hospital. Data were collected on demographics, medical history, and %TBWL at 3, 6, and 12 months post-operatively. Pearson’s correlation matrices and multiple linear regression analyses were performed.

Results

Most patients (88.1%) were female with a mean age of 44 years. The mean volume of stomach resected was 1047.0 cubic centimeters, and the median weight resected was 123.0 g. Follow-up data were available for 44 patients at 1-year post-operation. There was no association between the volume and weight of stomach resected and %TBWL at 1-year post-operation; however, greater %TBWL was associated with younger patient age (r =  − 0.525, p < 0.001).

Conclusion

One year after SG, no associations between %TBWL and the volume and weight of stomach resected were observed.

Key Points

• Neither weight nor volume of stomach resected correlated with %TBWL 1-year post-SG.

• Younger patient age was correlated with greater %TBWL 1-year post-SG.

• Lower pre-operative BMI was not correlated with greater %TBWL 1-year post-SG.

• Sex was not correlated with %TBWL post-SG, but 88% of the population was female.
