Possible reasons of insufficient efficacy of laparoscopic gastric bypass in surgical treatment of metabolic syndrome

Abstract

OBJECTIVE. The study assessed an efficacy of laparoscopic gastric bypass (LRGB) in correction of main components of metabolic syndrome (MS). The authors revealed the possible reasons of insufficient efficacy of operation. MATERIAL AND METHODS. Results of LRGB were estimated in 228 patients who underwent operation during 5 years. Index of body mass, % EBMIL, lipid spectrum, level of glycemia, content of leptin and ghrelin were considered. RESULTS. The high efficacy of operation influence on MS was found in young age groups. Other groups had lower efficacy of operation. The reason was in gastrointestinal tract reconstruction that resulted in decrease of body mass, regress of associated diseases, change of key hormones which regulated energy metabolism, homeostasis of glucose and lipids. The ghrelin level didn’t have a determining value and didn’t influence on decrease of MT after operation. CONCLUSIONS. The operation effectively influenced on all possible components of MS, but the ghrelin content wasn’t determinative for long-term regulation of body mass loss and reduced the efficacy of operation.
