DETERMINATION OF OPTIMAL TERMS FOR EXECUTION OF RADICAL BARIATRIC INVASIONS AFTER INTRAGASTRIC BALLOONING OF STOMACH THROUGH RESEARCH OF CHANGES IN THICKNESS OF GASTRIC WALL AMONG PATIENTS WITH MORBID OBESITY

Abstract

38 patients with morbid obesity were treated who were subject to intragastric ballooning of stomach before execution of radical bariatric invasions (gastric-by-pass). To evaluate the thickness of gastric wall 12 patients were subject to intragastric endosonography before insertion of balloon. Thickness of gastric mucosa and muscular layer in three anatomic sections of stomach were evaluated: bottom, body and antrum. Similar endosonographic measures were done for all 12 patients on the 1st, 7th and 14th day after extraction of the balloon. 12 patients without obesity were used as a group for control. The most significant endosonographic changes in thickness of gastric wall were fixed on the first day after extraction of balloon from patients with morbid obesity. At this, thickening of wall happens exclusively due to gastric mucosa thickening. Decrease in thickness of gastric wall is observed on the 7th day after balloon extraction, while on the 14th day after extraction the wall decreased to normal indicator. Given the fact that on the 1st day after balloon extraction the endosonographic results showed thickening of gastric wall by 2 millimeters as compared to indicator before balloon insertion, we opine that the radical bariatric invasion on the first day upon extraction is inadvisable. The thickness of gastric wall comes back to its normal position on the 14th day after balloon was extracted. Therefore it is recommended to execute radical bariatric invasion not earlier than by this term.
