Factors implicated in surgical complications and baros index after bariatric surgery

Object Roux-en-Y gastric bypass is the gold standard treatment for morbid obesity, although failure rates may be high, particularly in patients with a BMI > 50 kg/m2. With improved understanding of the neuropsychiatric basis of obesity, deep brain stimulation (DBS) offers a less invasive and reversible alternative to available surgical treatments. In this decision analysis, the authors determined the success rate at which DBS would be equivalent to the two most common bariatric surgeries. Methods Medline searches were performed for studies of laparoscopic adjustable gastric banding (LAGB), laparoscopic Roux-en-Y gastric bypass (LRYGB), and DBS for movement disorders. Bariatric surgery was considered successful if postoperative excess weight loss exceeded 45% at 1-year follow-up. Using complication and success rates from the literature, the authors constructed a decision analysis model for treatment by LAGB, LRYGB, DBS, or no surgical treatment. A sensitivity analysis in which major parameters were systematically varied within their 95% CIs was used. Results Fifteen studies involving 3489 and 3306 cases of LAGB and LRYGB, respectively, and 45 studies involving 2937 cases treated with DBS were included. The operative successes were 0.30 (95% CI 0.247–0.358) for LAGB and 0.968 (95% CI 0.967–0.969) for LRYGB. Sensitivity analysis revealed utility of surgical complications in LRYGB, probability of surgical complications in DBS, and success rate of DBS as having the greatest influence on outcomes. At no values did LAGB result in superior outcomes compared with other treatments. Conclusions Deep brain stimulation must achieve a success rate of 83% to be equivalent to bariatric surgery. This high-threshold success rate is probably due to the reported success rate of LRYGB, despite its higher complication rate (33.4%) compared with DBS (19.4%). The results support further research into the role of DBS for the treatment of obesity.

It is very important to learn from surgical complications. For this reason, research is vital in surgical practice. Clinical epidemiology and statistics provide the methodology for analyzing data and drawing conclusions. Thus, every surgeon should understand the basics of clinical epidemiology in order to know how to improve his or her practice. This chapter provides a background in epidemiology and the basic statistical methods that are commonly use in bariatric surgical research. A thorough knowledge of the different types of clinical studies and commonly used statistical tests is imperative for the clinician to have in order to interpret data accurately. If necessary the help of a biostatistician will ensure appropriate statistical tests are applied and results and conclusions of studies are credible.

Background: Hepatic steatosis is associated with increased surgical complications in patients undergoing bariatric surgery. The aim of this study was to evaluate the effect of phentermine in reducing hepatic steatosis, adipose tissue and surgical complications in patients undergoing bariatric surgery. Methods: This study is a two-arm, double-blind, randomized, controlled pilot trial of 64 adult subjects with BMI >35 kg/m2 selected for bariatric surgery randomized to phentermine 15 mg once daily for 8 week or placebo. Both groups adhered to a hypocaloric diet and individualized exercise program. The primary end point was the reduce frequency of hepatic steatosis measured by ultrasound and the reduce adipose tissue through fat mass in total kilograms or percentage. Key secondary points were the prevalence of surgical complications. Baseline and final biochemical parameters and blood pressure too were assessments. Results: Phentermine group the frequency of hepatic steatosis decreased 19%, and the percentage of patients with a normal ultrasound increased from 9% to 20% (p= 0.053). Likewise, the decrease in fat mass in kilograms was greater in the phentermine group (56.1 kg vs. 51.8 kg, p=0.02), and a significant decrease in the HOMA-IR index was observed regardless of weight loss. No differences in surgical complications were observed between groups. Phentermine was well tolerated; no differences were observed in the frequency of adverse events between the groups. Conclusions: Phentermine decreased the proportion of individuals with hepatic steatosis by 19%, promoted a greater loss of fat mass in kilograms, and decreased insulin resistance among candidates for bariatric surgery.
