Electrical function of the abdominal muscles after combined plastic of extensive median hernias in the context of connective tissue dysplasia

Abstract

Relevance. Improving the electrical function of abdominal muscles in patients with extensive median hernias of the anterior abdominal wall can be facilitated by optimizing the choice of methods for combined hernioplasty, taking into account the clinical severity of connective tissue dysplasia among the hernia carriers.
 Objective. Study the electrical function of abdominal muscles after the methods of combined hernioplasty of extensive median hernias, taking into account the severity of connective tissue dysplasia among the hernia carriers.
 Results. The average numbers of electromyogram frequencies of the abdominal muscles of patients with extensive median hernias from the group without clinical signs of connective tissue dysplasia were almost the same after all the applied methods of combined hernioplasty. The predominance of the rectus muscles electric function over the lateral abdominal muscles among the patients of this group was 33,5 %.
 Electrofunctional rehabilitation of the abdominal muscles of patients in the second group of examinations depended on the method of combined hernioplasty and changed in the event of an increase or decrease in the severity of connective tissue dysplasia. The recovery of electroactivity of abdominal muscles in the postoperative period in patients from the second group was more significant with an increase in the number of abdominal muscles applied to aponeuroses and vagina of relaxing sections, which contributed to an increase in mobility and contractility of the musculoaponeurotic layers of the anterior abdominal wall.
 Conclusions. Thus, with an increase in the severity of connective tissue dysplasia in patients with extensive median abdominal hernias, the method of combined hernioplasty with the most pronounced relaxing effect in relation to the anterior abdominal wall promoted optimal rehabilitation of abdominal muscles.
