Abstract: Background: Patients undergoing sleeve gastrectomy (SG) experience transformative changes in eating-related experiences that include eating-related symptoms, emotions, and habits. Long-term assessment of these endpoints with rigorous patient-reported outcome measures (PROMs) is limited. We assessed patients undergoing SG with the Body-Q Eating Module PROMs.
Methods: All patients evaluated at the Emory Bariatric Center were given the Body-Q Eating Modules questionnaire at preoperative/postoperative clinic visits. Rasch scores and prevalence of relevant endpoints were assessed across six time-points of interest: preoperatively, post-operative months 0-6, 7-12, 12-24, 24-36, and over 36. Student's t-test and Chi-square test were used for analysis.
Results: Overall, 1,352 questionnaires were completed pre-operatively and 493 postoperatively. Survey compliance was 81%. Compared to the pre-operative group, the post-operative group had lower BMI (39.7 vs. 46.4, p < 0.001) and higher age (46.3 vs. 44.9, p = 0.019). Beginning one year after SG, patients experience more frequent eating-related pain, nausea and constipation compared to pre-operative baseline (p < 0.05). They also more frequently experience eating-related regurgitation and dumping syndrome-related symptoms beginning post-operative year two (p < 0.05). In the first year after SG, patients more rarely feel eating-related embarrassment, guilt, and disappointment compared to pre-operative baseline (p < 0.05). These improvements disappear one year after SG, after which patients more frequently experience feeling out of control, unhappy, like a failure, disappointed, and guilty (p < 0.05). In the first year after SG, patients experience an increased frequency in positive eating behaviors (ate healthy foods, showed self-control, stopped before full; (p < 0.05). Only two eating-related behavior improvements persist long-term: feeling in control and eating the right amount (p < 0.05).
Conclusions: Patients undergoing SG may experience more frequent eating-related symptoms, distress, and behavior in the long-term. These findings can enhance the pre-operative informed consent and guide development of a more tailored approach to postoperative clinical management such as more frequent visits with the dietician.
