Objective. Studying of first results of application of 3D visualization in various laparoscopic interventions. Materials and methods. There were performed 169 operations: 27 transabdominal preperitoneal plasties of inguinal hernias, 19 intraperitoneal alloplasties of umbilical and postoperative ventral hernias with suturing of hernia defect, 1 retromuscular alloplasty of umbilical hernia, 6 reconstructions of anterior abdominal wall for dyastasis of rectal abdominal muscles, 103 plasties of

... al hernias with fundoplications, 7 Heller's cardiomyotomies and Dor's fundoplication, 1 subtotal, 3 atypical gastric resections and 2 sleeve gastric resections for obesity. Results. 3D laparoscopy have simplified and accelerated the parietal peritoneum suturing in conduction of transabdominal preperitoneal plasties of inguinal hernias, as well as while performance of intraperitoneal alloplasties of umbilical and postoperative ventral hernias – the hernia defect suturing. While doing the hiatal hernia plasty, fundoplication with crurorrhaphy 3D laparoscopy have provided the additional advantages of manipulations improvement in special anatomic zones. Analogous advantages were shown in gastric operations, using 3D visualization. Intra- and postoperative complications were absent, as well as the hernias recurrence in the 6 mo-1.5 yr follow-up. Conclusion. The 3D visualization guarantees a rapid and highly-precision performance of complex manipulations in technically hard anatomical zones. Further accumulation of the material and comparison of results of 3D and 2D laparoscopy in prospective investigations, using objective parameters, as well as studying of expediency for 3D visualization selective application, for instance while performance of the most complicated operative stages are necessary.
