With the high prevalence of obesity and associated comorbidities, the costs of health services produce a great economic impact. The objective of this work was to evaluate the economic benefits of bariatric surgery and to relate the costs to the impact on the health of the individual. A historic cohort study was conducted, with review of medical charts of 194 patients who fulfilled the inclusion criteria for the study. The costs for medications, professional care, and examinations in the pre- and postoperative periods were analyzed, taking into consideration the comorbidities DM2, SAH, and dyslipidemia. The study demonstrated a reduction in the medical costs in the course of the postoperative period, in relation to expenses for medications, professional care, and examinations in the preoperative period. Comparing the preoperative expenses with different times in the postoperative period, a statistically significant difference was seen at all time evaluated (p < 0.001). The resolution of comorbidities was higher than 95% at 36 months after surgery. No statistically significant difference was seen with respect to the prevalence of comorbidities between the sexes in the pre- and postoperative periods (p > 0.05). With regard to age, younger patients showed lower rates of comorbidities in the pre- and postoperative periods (p < 0.001). The costs of the surgery are high, but the expenditures for medications, professional care, and examinations decrease progressively after the operation, where this is more evident in patients with more associated comorbidities.
After 60 months of follow-up, the most relevant predictors of weight loss after RYGB were lower preoperative BMI and WC, videolaparoscopy as surgical access, and younger age. Further studies must be carried out to elucidate the impact of these factors on RYGB outcomes.
BackgroundBecause of the high prevalence of obesity, there is a growing demand for bariatric surgery worldwide. The objective of this systematic review was to analyze the difference in relation to cost-effectiveness of access route by laparoscopy versus laparotomy of Roux en-Y gastric bypass (RYGB).MethodsA systematic review was conducted in the electronic databases MEDLINE, Embase, Scopus, Cochrane and Lilacs in order to identify economic evaluation studies that compare the cost-effectiveness of laparoscopic and laparotomic routes in RYGB.ResultsIn a total of 494 articles, only 6 fulfilled the eligibility criteria. All studies were published between 2001 and 2008 in the United States (USA). Three studies fulfilled less than half of the items that evaluated the results quality; two satisfied 5 of the required items, and only 1 study fulfilled 7 of 10 items. The economic evaluation of studies alternated between cost-effectiveness and cost-consequence. Five studies considered the surgery by laparoscopy the dominant strategy, because it showed greater clinical benefit (less probability of post-surgical complications, less hospitalization time) and lower total cost.ConclusionThis review indicates that laparoscopy is a safe and well-tolerated technique, despite the costs of surgery being higher when compared with laparotomy. However, the additional costs are compensated by the lower probability of complications after surgery and, consequently, avoiding their costs.
BackgroundAlthough Brazilian National Public Health System (BNPHS) has presented advances
regarding the treatment for obesity in the last years, there is a repressed demand
for bariatric surgeries in the country. Despite favorable evidences to
laparoscopy, the BNPHS only performs this procedure via laparotomy.Aim1) Estimate whether bariatric surgeons would support the idea of incorporating
laparoscopic surgery in the BNPHS; 2) If there would be an increase in the total
number of surgeries performed; 3) As well as how BNPHS would redistribute both
procedures.MethodsA panel of bariatric surgeons was built. Two rounds to answer the structured
Delphi questionnaire were performed.ResultsFrom the 45 bariatric surgeons recruited, 30 (66.7%) participated in the first
round. For the second (the last) round, from the 30 surgeons who answered the
first round, 22 (48.9%) answered the questionnaire. Considering the possibility
that BNPHS incorporated laparoscopic surgery, 95% of surgeons were interested in
performing it. Therefore, in case laparoscopic surgery was incorporated by the
BNPHS there would be an average increase of 25% in the number of surgeries and
they would be distributed as follows: 62.5% via laparoscopy and 37.5% via
laparotomy.Conclusion1) There was a preference by laparoscopy; 2) would increase the number of
operations compared to the current model in which only the laparotomy is available
to users of the public system; and 3) the distribution in relation to the type of
procedure would be 62.5% and 37.5% for laparoscopy laparotomy.
