Background
Vertically banded gastroplasty or adjustable gastric banding often result in weight regain, complications, or side effects. Failed restrictive bariatric procedures can be converted in revisional laparoscopic Roux-en-Y gastric bypass (LRYGB). This study aimed to compare weight loss, evolution of comorbidities, and quality of life (QOL) between primary versus revisional LRYGB.
Methods
Between 2004 and 2012, 374 patients underwent LRYGB as primary or revisional surgery performed by a single surgeon. Patient data were retrospectively reviewed; questionnaires of QOL were sent to all patients. Outcomes were evaluated according to Bariatric Analysis and Reporting Outcome System (BAROS) taking into account excess body mass index loss (EBMIL), correction of comorbidities, improvement in QOL, and complications.
Results
Two hundred thirty-two patients (62 %) responded to the questionnaire, 163 patients in the primary group and 69 in the revisional group. Median follow-up was 36 months (12–108). Median percentages of EBMIL were, respectively, 74 % (26.8–126.8) and 50 % (−31.6–124.2) in the primary and the revisional groups (p < 0.01). Median BAROS score reached 6.5 (−2–9) in the primary group, against 4.3 (−1.8–9) in the revisional group (p < 0.01). There were significantly less “fair” and more “excellent” scores in the primary group, considering initial BMI before gastroplasty. Arterial hypertension and sleep apnea syndrome resolved, respectively, in 51 and 56 % in the primary group and only in 29 and 33 % in the revisional group (p < 0.01).
Conclusions
According to BAROS score, revisional LRYGB for failed restrictive procedures provided poorer results than primary LRYGB in terms of weight loss, resolution of comorbidities and QOL.
