[The dependence of weight loss on the dimensions of neoventriculus in patients after gastric banding].
BACKGROUND
At present the surgical procedure is accepted in the physicians' opinion of the cases of morbid obesity in patients where the conservative therapy has failed. Bariatric surgery offers an effective, standardized, and safe way to radical and long-term loss of weight. The laparoscopic gastric banding is the most frequent procedure in patients with morbid obesity.


OBJECTIVE
The aim of the study was to consider if the statistic dependence exits between the weight loss and the dimensions of neoventriculus in patients after gastric banding or between the weight loss and the width of artificial stenosis created operatively.


METHODS
One hundred and eighty four patients with morbid obesity underwent the laparoscopic gastric banding from January 1, 2001 to July 30, 2006. The dimensions of neoventriculus and the width of artificial stenosis were measured after the operation. The patients were divided into three subgroups according to the dimensions of neoventriculus and the width of artificial stenosis. The patients were followed 2 years and the weight loss was registred. The results were statistically evaluated by correlative ratio.


RESULTS
The correlative ratio were calculated between weight loss and the dimensions of neoventriculus and between the weight loss and the width of artificial stenosis created operatively. The analysis showed that there was no statistic difference between the tested parameters.


CONCLUSIONS
The study has showed that the success of gastric banding does not depend on the dimensions of neoventriculus and on the width of artificial stenosis but it depends on orderliness of patients. It means the adherence of dietary limitations and recommandations.
