Abstract

Aim - to determine morphometrically and anatomically justified sites for laparoscopic port placement in pubertal girls by means of geometric modeling of the anterior abdominal wall regions and the construction of a numerical model based on the obtained anthropometric data.

Materials and methods. A morphometric study was conducted in 112 girls aged 10-17 years without pathology of the musculoskeletal system, using mathematical modeling. Based on anatomical landmarks - the xiphoid process, umbilicus, iliac spines, and pubic symphysis - a triangular model of the anterior abdominal wall was constructed.

Results. A significant increase in the area of the anterior abdominal wall was established in the older pubertal group, while symmetry between the right and left halves was preserved. The optimal placement of laparoscopic ports corresponded to the coordinates of the triangle centroids (y=9,73±0.05 cm).

Conclusions. Geometric modeling allows standardization of port placement on the anterior abdominal wall in pubertal girls and may reduce the invasiveness of surgical intervention.

The study was conducted in accordance with the principles of the Declaration of Helsinki. The study protocol was approved by the local ethics committee of the indicated institution. Informed consent was obtained from the patients for participation in the study.

The authors declare no conflict of interest.
