Relationship between residual gastric area and weight loss after sleeve gastrectomy: A Cohort study.

ABSTRACT:

Background

The aim of this study is to evaluate the impact of the actual size and area of the remnant stomach, as measured by Upper gastrointestinal tract radiography, on weight loss after sleeve gastrectomy.

Materials and methods

From May 2017 to December 2019, 56 patients with morbid obesity were admitted to the Department of Medical and Surgical Sciences, University of Foggia and underwent laparoscopic sleeve gastrectomy.

Results

56 patients underwent sleeve gastrectomy with a mean age of 43,5 ± 11 years of which 40 were female. The mean Excess Weight Loss (EWL) at 1 month was 24,09 ± 15,04%, at 6 months was 27,07 ± 19,55% and at 12 months was 69,9 ± 23,7%. The mean Excess Body Mass Index Loss (EBMIL) at 1 month was 23,1 ± 12,5%, at 6 months was 56,6 ± 19,7% and at 12 months was 69,7 ± 23,7%.The EWL % was correlated with the residual stomach area (RSA) at 1 month (r = -0,242 p = 0,072), at 6 months (r = -0,249 p = 0,064) and at 12 months (r = -0,451 p = 0,0005).The EBMIL % was correlated with the RSA at 1 month (r = -0,270; p = 0,043), at 6 months (r = -0,270; p = 0,043) andat 12 months (r = -0,46; p = 0,0004).

Conclusion

A greater postoperative EWL % was correlated with a smaller RSA and this resulted in a statistically significant change at 12 months after surgery.
