Despite the recognition of bariatric surgery as the only effective method of weight reduction, we remain in search of minimally invasive methods, both for the treatment of obesity and preparation of patients for surgical procedures.The aim of the study was to determine intragastric balloon (Allergan) implantation results as the only method of treating obesity, and patient preparation for further stages of abdominal hernia operations, as well as other surgical procedures.Material and methods. The study presented own results considering the use of Bioenteric Intragastric Balloons (BIB system) in the treatment of pathological obesity, and preparation of patients for bariatric surgery and abdominal hernia operations. The study group comprised 18 female and 7 male patients. Average patient age amounted to 50.6 and 54 years, respectively. Indications for intragastric balloon insertion were as follows: preparation for hernia (10 cases) and bariatric (5 patients) operations, and weight reduction management (8 patients). In two cases the implantation of the intragastric balloon served the preparation for gynecological and orthopedic (vertebral column) operations. One female patient was prepared for both bariatric and hernial surgery. The procedure was performed under general anesthesia. Statistical analysis considered 22 patients (one female patient was excluded from analysis, due to death, two other were excluded because of lack of sufficient data).Results. In case of two patients the intragastric balloon system was removed before 6 months had elapsed because of intolerance. One female patient died during the observation period for reasons not related to the procedure. The obtained BMI reduction ranged between 2 and 6 kg/m2, which amounted to a maximum weight loss of 24 kg. In one patient a weight gain of 2 kg was observed. Considering patients prepared for abdominal hernia operations weight reduction was greater and better maintained after the removal of the BIB system.Conclusions. According to the authors of the presented study the intragastric balloon serves its role as a bridge to bariatric procedures and weight reduction, before planned extensive postoperative hernia operations. The use of the intragastric balloon only to reduce weight has no medical and economic justification.
