Abstract
BACKGROUND: Weight loss after bariatric surgery varies among patients. Patients who do not comply with self-monitoring are predicted to lose less weight than those who comply with self-monitoring. OBJECTIVE: To assess the effect of compliance with self-monitoring behavior on long-term %excess weight loss (%EWL) and %total weight loss (%TWL) among patients receiving laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB). METHODS: We used retrospective analysis to evaluate the self-monitoring behavior of patients and their weight changes throughout a 2-year follow-up. The participants were divided into two groups: group 1 consisted of participants who kept self-monitoring behavior records for all follow-ups and group 2 consisted of participants who kept self-monitoring behavior records for only six months of follow-up. Our investigators used telephone interviews to collect the data. By comparing %EWL and %TWL, we assessed the possible relationship between the long-term self-monitoring behavior, weight loss outcome, and operation type. RESULTS: There were 384 included samples. %EWL was significantly different between group 1 and group 2, and group 1 participants had better outcomes regardless of operational method. In group 2, LRYGB patients had better %EWL outcomes than LSG patients. CONCLUSIONS: Patients with long-term self-monitoring behaviors have better %EWL and %TWL. Patients in LRYGB group had better weight loss outcomes than the LSG group.
