Argon Plasma Effect about Anastomosis was Significant to Inhibit the Weight Regained in Patients Undergoing Gastric Bypass

About 40% of the population is overweight. It is estimated that there are about 80,000 deaths per year in Brazil for reasons arising from obesity. Bariatric surgery has been the most effective method for the treatment and prevention of complications caused by morbid obesity. The gastric bypass has shown good short term results in significant reduction of body weight. However, in the long run about 10 to 20% of patients tend to weight regained. This number seems to be relatively low; the reality is significantly higher when surgery is not accompanied by a long-term change in lifestyle. Thus, it was hypothesized that by applying argon plasma on the anastomosis, the weight regained is avoided. The aim of this work was to study the effect of argon plasma fulguration in the weight regained in patients undergoing gastric bypass. Of the 37 patients who underwent gastric bypass 24(75%) were female and 8(25%) were male. Considering the gastric bypass, the mean preoperative weight was 117.61 Kg. After the average weight surgery was 79.94 Kg. The mean difference of pre and post-operative weight was 37.66 kg, the difference being significant (p<0.0001). Regarding the use of argon, the average pre intervention weight was 94.52. The average difference pre and post intervention was 5.87 kg, with statistically significant (p<0.0001). There was a significant correlation between use of the ring and smaller diameter of the anastomosis at the third session (p=0.019). The average size of the pouch was 5. There was no statistical correlation between size of the pouch and efficacy of argon use. It was concluded that after application of argon was no significant reduction in the average weight of the patients, about 50% of patients, especially female.
