Materials and methods
This study was a single-institution, retrospective cohort study at a Veterans Affairs (VA) medical center with specialty in bariatric surgery. Data collection was carried out by utilizing the VA Computerized Patient Record System. The Institutional Review Board (IRB) committees from the VA medical center as well as our institution have approved the study.
Baseline characteristics
A total of 336 veteran patients were initially screened, of which 174 patients were excluded (120 patients did not receive bariatric surgery and 54 patients underwent surgery outside the VA medical center). This left 162 patients to be included in the study. There were 84 patients who underwent the RYGB procedure, 48 patients received SG, and 30 patients had LAGB. Regarding the surgical technique, laparoscopic method was the primary technique performed in all 3 bariatric procedures (RYGB: 96.4%
Discussion
With the increased prevalence of obesity and its associated co-morbid medical conditions, the number of bariatric surgeries performed in the United States was up>50% within 2 years between 2011 and 2013 [28]. Even with its increasing popularity, comparative effectiveness evidence among the most common bariatric surgery procedures in the United States, especially in the veteran population, is limited. In the present study, we investigated the short-term outcomes of weight loss and
Conclusion
In the veteran population, the RYGB procedure appears to achieve better short-term outcomes in terms of weight reduction and management of obesity-associated co-morbid conditions compared with the SG and LAGB procedures. SG may be the next best option for bariatric surgery in patients who are not candidates for RYGB.
