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.

Key Points
1. Long-term self-monitoring behaviors enhance effect of weight loss after bariatric surgery.
2. The outcome of bariatric surgery is based on weight loss after bariatric surgery, but the outcome of weight loss is affected by different variables, that one is self-monitoring behaviors.
3. Patients in LRYGB group had better weight loss outcomes than the LSG group.
