Aim. To study features ofthesurgical anatomy of intercostal nerves in the area of the lateral edge rectus sheath. Material and Methods. We investigated 88 floating corpses of both sexes, without pathology of abdominal wall. There were 45% corpses of males (middle age - 53.8±11.9 years) and 55% - a females (51.9±13.2 years).We determined the number of intercostal nerves in the area of the lateral edge rectus sheath. We explored options of the penetration intercostal nerves in rectus abdominis. Results and Discussion. The number of intercostal nerves in the area of the lateral edge rectus sheath ranged from 5 to 7, but most of the nerves were 6 (70%).In the presence of 6 intercostal nerves statistically significant difference between persons of male and female were not found. 5 intercostal nerves were observed in males (67%), and 7 of nerves - in females (64%).We have found the posterior (63%) and lateral (37%) variants penetration intercostal nerves in the rectus abdominis. The posterior variant was significantly more common in females (74%), and a lateral variant - in males (65%). Conclusions. We have received new data on the surgical anatomy intercostal nerves in the area of the lateral edge rectus sheath, which must be considered when performing hernia repair.
