Resected gastric volume has no influence on early weight loss after laparoscopic sleeve gastrectomy.
Surg Obes Relat Dis. 2018 02; 14(2):129-135.SO

Abstract

BACKGROUND

Laparoscopic sleeve gastrectomy (LSG) has become a popular procedure for treatment of obesity, but it is still undecided whether resected gastric volume (RGV) is related to weight loss after LSG.

OBJECTIVE

The aim of this study was to investigate the influence of RGV and other factors on weight loss at 1 year after LSG in a Chinese population.

SETTING

University Hospital, China.

METHODS

A total of 53 patients who underwent LSG between August 2015 and July 2016 were enrolled. The LSG procedure and RGV measurement were performed using standardized techniques. Patients were followed-up every 3 months in the first year and 6 monthly after that. Correlations between the percentage of excess weight loss at 1 year (%EWL-1 yr) and RGV and other parameters were evaluated.

RESULTS

All patients completed at least 1 year of follow-up. No major complications or cases of underweight were seen. Mean body mass index (BMI) at 1 year after LSG was significantly lower than the baseline BMI (31.1 ± 3.8 kg/m2 versus 39.0 ± 6.6 kg/m2; P<.001). Mean %EWL-1 yr was 58.8%, and mean RGV was 862.6 ± 209.5 mL. No correlation was observed between %EWL-1 yr and RGV (r = -0.071; P = .613). The %EWL-1 yr was correlated with preoperative weight, BMI, RGV/weight, and RGV/BMI. RGV was positively correlated with preoperative weight and BMI. Patients who achieved satisfactory weight loss (%EWL ≥50%) had significantly lower baseline BMI, and higher RGV/weight and RGV/BMI, than those who had inadequate weight loss. However, RGV was not significantly different between the 2 groups.

CONCLUSIONS

Weight loss effect at 1 year after LSG was not associated with RGV in this Chinese population. RGV was influenced by the weight and BMI.
