Summary

Introduction:
Obesity increases the risk of developing a range of diseases. The treatment of obese patients is very demanding and long-lasting and the weight loss achieved may not be permanent. One of the most efficient means of treatment of obesity and related metabolism diseases is major surgery.

Methodology:
In connection with a prospective pilot study that examined the influence of gastric sleeve resection on the body constitution, we examined 42 morbidly obese women by means of bioelectrical impedance analysis (BIA). All patients were carefully selected according to IFSO-Guidelines (persons with BMI ≥ 40 kg/m² or with BMI ≥ 35 kg/m² with associated comorbidities). The patient selection, surgical procedures (laparoscopic gastric tubulisation) and the 12-month observation period took place from April 2010 to January 2012.

Results:
The average weight in the group was 116,4 ± 17,6 kg, with the average BMI 42.4 ± 4.8 kg/m² and average waist girth 112,0 ± 10,3 cm. 12 months after surgery, the average weight loss was 30.8 kg. The average BMI of the group came down in average from 42.4 kg/m² (3^rd grade obesity) to 31.0 kg/m² (1^st grade obesity). The waist girth was reduced in average by 18.2 cm. During the 12-month period after surgery there was a statistically significant decrease in body weight, body fat and the amount of the body cell mass (BCM) in all of the women in the study. At the same time, the amount of total body water (TBW), intracellular water (ICW) and extracellular water (ECW) changed, yet only the ECW decrease was statistically significant. The waist and hips girth reduction is also marked.

Conclusion:
In the 12-month period following resection significant weight loss occurred, both in the total weight and in the body fat and body water weight. We can conclude that, from the point of view of weight loss and body constitution, our results clearly indicate a very positive effect of the surgical treatment of extreme obesity by means of a laparoscopic gastric tubulisation method.
