MEDIUM-TERM EFFICACY OF THE ENDOSCOPIC TRANSORAL OUTLET REDUCTION (TORE) FOR WEIGHT REGAIN AND DUMPING SYNDROME (DS) AFTER GASTRIC BY-PASS (GB)

Aims The aim is to evaluate the results of TORe on weight loss, patient safety, and as treatment for symptoms by DS in patients that had dilation of the stoma after GB,

Methods A retrospective analysis was conducted on consecutive patients who underwent TORe between May 2014 and October 2020 at our Hospital. Sigstad’s Scoring System (SS), Early and Late Arts Dumping Questionnaire (EADQ and LADQ), body mass index (BMI), percentage of total body weight loss, and percentage of excess weight loss (%TBWL,%EWL), were analyzed before and after the procedure at 6 and 12 months.

Results 81 patients (mean age 45,8 years, 78% female) underwent TORe. Baseline BMI was 35,8±5,8. Based on SS>7, 51 patients (63%) were classified as dumpers (mean SS 15,59±5,37). Mean Early ADQ was 8,69±5,7, mean Late ADQ 5,63±4,22. All patients reached 12 months follow-up. No adverse events were observed.

Mean ΔBMI,%EWL and%TBWL at 6 and 12 months were respectively 3,76±3,91 and 3,45±3,6, 54,7±136,3 and 40,6±59,1, 10,2±7,2 and 9,3±9,1.

35 (69%) and 32 (63%) dumper patients had resolution of Dumping Syndrome symptoms (SS<7) at 6 and 12 months. Performing Paired T-test, statistically significant decrease of all scores was observed: -10,1±7,1 and -9,5±7,5 for SS (p-value<0.001), -5,5±6,0 and -5,4±6,1 for EADQ (p<0.001), -4,0±4 and -3,8±4,4for LADQ (p<0.01) (fig.1).
