Analysis of quality of life in the medium-long term in bariatric patients using the modified BAROS system

Key Points

To evaluate the quality of life, weight loss percentages, and resolution of comorbidities in bariatric patients using the modified BAROS system.
Single-center ambispective study
Used the modified BAROS questionnaire with the M-A II QoL questionnaire
Included 115 bariatric patients with a 7-year average follow-up
Average weight loss: 33 kg/m² with a significant difference between SG and RYGB (p < 0.0001)
EWL was 22.25% for SG and 30.94% for RYGB (p = 0.0001)
49% experienced resolution of comorbidities, with higher rates in SG (60%) than RYGB (40%)
70% reported excellent or very good outcomes
Mean BAROS score was 5.7, significantly higher for RYGB than SG (p = 0.002)

Abstract

Objective:To analyze quality of life (QoL), percentage of excess weight loss (EWL), and resolution of comorbidity using the modified BAROS (Bariatric-Analysis-and-Reporting-Outcome-System) questionnaire.Method: We used the Moorehead-Ardelt II (M-A II) QoL-questionnaire within the modified BAROS in its Spanish-validated version.This was a single-center ambispec-tive study.Results: The analysis included 115 patients with a mean follow-up of 7 years post-surgery (SD, 2.11).48 underwent sleevegastrectomy (SG), 67 Roux-en-Y gastric-bypass (RYGB), both laparoscopic.The mean age was 47.65 years (IQR: 27-63) (p < 0.975).The average body mass index reduction was 33 kg/m 2 (SD, 6.34).Weight loss: SG 98 kg, RYGB 83 kg (p < 0.0001).EWL: SG 22.25% vs RYGB 30.94% (p = 0.0001).Comorbidity resolution: 49% (p = 0.033), SG 60% vs RYGB 40% (p = 0.033).Postoperative complications: 3% (SG 2% vs RYGB 1%).The mean BAROS score was 5.7 points (SD, 2.71), SG 4.7 vs RYGB 6.4 (p = 0.002).Excellent or very good outcomes were observed in 70%, with failure rates below 8%.In terms of QoL (M-A II), the area rated as "very good" was work activity (95.45%), while "very poor" was sexual-relationships (18.4%).Conclusions: Both SG and RYGB show favorable medium-to long-term outcomes in terms of weight loss, comorbidity resolution, and improved quality of life.
