On the features of the preperitoneal space multifascial structure in clinical and anatomical issues

Abstract

AIM: to determine the prospects for the preventive endoprosthetics of the abdominal wall at preventing the development of postoperative ventral hernias. MATERIALS AND METHODS: A meta-analysis of the literature data performed to determine the effectiveness of preventive endoprosthetics for the prevention of ventral hernia formation. Topographical study has been conducted to explore the most promising levels of the mesh location. RESULTS: During the meta-analysis it has been found that performing preventive endoprosthesis of the anterior abdominal wall t in the preperitoneal space reduces the frequency of ventral hernias. There were no significant differences in the frequency of infectious complications and serom in the experimental and control groups according to studied publications. During the preparation it has been distinguished that between the transverse fascia and the peritoneum there is a preperitoneal fascia consisting of two leaves, which is most manifest in the lateral parts. In the umbilical region above linea arcuata the preperitoneal fascia is thinned and represented by separate fibers that are difficult to differentiate as a structure between the transverse fascia and the peritoneum. In the lateral parts of the abdominal wall, the preperitoneal fascia is well expressed. It has been distinguished that the retroperitoneal fascia, formed by the junction of two sheets of the Gerot fascia continues into the fascia between the transverse fascia and the peritoneum. CONCLUSION: Preventive endoprosthesis of the anterior abdominal wall is an effective and safe method of preventing the formation of postoperative ventral hernias. The anterior abdominal wall is characterized by a complex multifascial structure, which is of fundamental importance for various types of surgery. Between the transverse fascia and the peritoneum there is preperitoneal fascia which is represented by two leaflets. Its continuation is the retroperitoneal fascia (5 figures, 2 tables, bibliography: 8 refs).
