RESUMO
PURPOSE: The feasibility of early telerehabilitation after bariatric surgery is unknown. The objective of this study was to assess the feasibility and perception of engaging in the online exercise protocol in patients during the first month after bariatric surgery. MATERIAL AND METHODS: A total of 67 patients, enrolled in a telerehabilitation program following bariatric surgery, completed a survey assessing their perception of the intensity, discomfort, and safety during exercise sessions. RESULTS: Forty percent of participants began exercising between 5 and 10 days after surgery. Seventy-one percent of patients did not experience discomfort during the first month of exercise, and those who reported discomfort mainly mentioned dizziness and abdominal pain. No significant differences were found in the presence of discomfort among different types of surgeries performed. There was a significant difference in the presence of discomfort between patients who started exercising before and after 15 days of surgery, with less discomfort reported in the group that started after 15 days. Ninety-eight percent of patients felt safe during online exercise sessions. Most participants perceived the intensity of the sessions as moderate. The most frequently mentioned benefits of exercise were increased energy, mood, and feeling more active. CONCLUSION: Telerehabilitation conducted during the first month after bariatric surgery was feasible and well tolerated by patients, providing a safe alternative for those patients who face difficulties with in-person interventions.
RESUMO
OBJECTIVES: Weight regain after bariatric surgery may be associated with behavioral, metabolic, or mechanical factors alone or in combination. The aim of this study was to investigate which factors are related to weight regain in the long-term after sleeve gastrectomy (SG). METHODS: A retrospective case-control study with 40 patients undergoing SG (32 women, 8 men; age 42.9 ± 10.7 y; preoperative body mass index 35 ± 2.8 kg/m(2)), was performed. Patients were grouped according percentile->50% (cases) or <50% (controls)-of weight regain (%WR cutoff: 25% of weight loss). Weight history, anthropometry, glucose, insulin, homeostasis model assessment-estimated insulin resistance (HOMA-IR), thyroid-stimulating hormone, resting energy expenditure, body composition, dietary survey, psychological test, and physical activity were recorded. Residual gastric capacity was estimated using a radiologic method. RESULTS (MEDIAN [P25-P75]): The evaluation was conducted 38.5 mo (34-41 mo) after SG. Percent weight regain ranged from 2.7% to 129.2% (25.4% [13-37.1]). Patients in the higher %WR group had a greater residual gastric volume (252.7 ± 108.4 versus 148.5 ± 25.3; P < 0.05) and the estimated volume was significantly correlated with %WR (r = 0.673; P = 0.023). Significantly higher body mass index (P = 0.001), resting energy expenditure (P = 0.04), fasting insulin (P = 0.01), and HOMA-IR (P = 0.02) were observed in the higher %WR group. A higher fat intake and a trend toward higher total energy intake were observed in the group with greater %WR. Clinical or borderline levels of anxiety were more frequently observed in the higher %WR group (70% versus 30%; P = 0.01). CONCLUSIONS: Results from the present study demonstrated that the most important factor associated with long-term weight regain after SG was residual gastric volume. Additional prospective studies with larger numbers of patients are necessary to confirm our results.
