Comparison of Dietary Quality and Surgical Satisfaction Between Patients With Suboptimal and Optimal Weight Loss After Sleeve Gastrectomy Using Food Tolerance Score and Bariatric Analysis and Reporting Outcome System Questionnaires.

PURPOSE

This study aimed to assess the association of dietary quality and surgical satisfaction with the amount of total weight loss (TWL) 1 year after laparoscopic sleeve gastrectomy (LSG) using the food tolerance score (FTS) and Bariatric Analysis and Reporting Outcome System (BAROS) questionnaires.

MATERIALS AND METHODS

This single-center retrospective study included patients who underwent LSG due to morbid obesity. Only those who have 1-year follow-up data were included and divided into 2 groups: suboptimal TWL (STWL) ≤20% and optimal TWL (OTWL) >20%. Clinical data and questionnaires recorded 1 year after surgery were collected. FTS was used to evaluate the degree of food tolerance, and BAROS assessed surgical outcomes, including weight loss, comorbidity changes, and quality of life (QoL). The total FTS and BAROS scores of the 2 groups were compared.

RESULTS

Of 580 patients, 159 were included. Patients in STWL (n=17) were significantly older than those in OTWL (n=142) (42.24±9.28 vs. 35.92±8.71 years old, P=0.006). The total FTS (1-30 points) for STWL and OTWL were 24.88±3.43 and 25.04±3.14, respectively (P=0.845). Although the total BAROS scores (maximum: 9 points) were significantly lower in STWL than in OTWL (5.96±1.48 vs. 7.20±1.40, P<0.001). The only variable that made this difference was weight loss. There were no significant differences in other variables, such as medical conditions, QoL, and complications.

CONCLUSION

In terms of FTS and BAROS score, there is no difference in postoperative satisfaction and QoL between STWL and OTWL after LSG, except for the degree of weight loss.
