The analysis of the first 14 operations of horizontal gastroplasty in patients with end-stage alimentary constitutional obesity was carried out, the operations being performed according to standard (9 patients) as well as laparoscopic method (5 patients). The mean body mass made up 133.6 kg, the mean height being 167.8 cm. Patients age was from 22 to 42 years. All the patients operated by laparoscopic method were women. Technique of laparoscopic horizontal gastroplasty is described, indications and contraindications to the operation are established. It is demonstrated, that laparoscopic gastroplasty, as well as previously performed 530 horizontal gastroplasties with the help of fluoric-lausan goffer band, performed in clinic since 1984, in present time is one of the most perspective method of surgical correction of obesity. The application of this method results in substantial and steady decrease of body mass of the operated patients with minimal risk of complications during surgical procedure as well as in postoperative period.
