Abstract:
Purpose:Dumping syndrome (DS) is an important but often underreported problem occurring after bariatric surgery. It is believed that gastric bypass procedures like Roux-en-Y Gastric By-pass (RYGB) and One-Anastomosis Gastric Bypass (OAGB) are more likely to cause DS than the pylorus-preserving Sleeve Gastrectomy (SG). The aim of this study was to evaluate the incidence of DS in patients undergoing SG, RYGB and OAGB.
Materials and Methods:A retrospective clinical study with 180 patients undergoing SG (n=50), RYGB (n=53) and OAGB (n=77) between 2016-2018 was performed. All clinical and demo-graphic data were assessed. The percentage of excess weight loss (%EWL) was used to evaluate weight reduction. 127/180 (70.6%) patients took part in an additional phone interview. The incidence of DS was evaluated using validated Sigstad Score.
Results:Information about the occurrence of dumping symptoms and patient satisfaction was obtained from 127 patients. Median follow-up was 20.0±11.4 months. Significant differences between the surgical procedures were found for the duration of surgery, complications, weight loss, incidence of DS and satisfaction postoperatively. DS occurred in 15.6% after SG, 56.4% after RYGB and 42.9% after OAGB. A higher weight loss was observed in patients who experienced dumping symptoms.
Conclusion:The present results show a clear superiority of SG regarding both perioperative results and incidence of DS compared to RYGB and OAGB and may impact clinicians and patients in their choice of procedure.
