[Classification criteria for anterior abdominal wall deformities].

To determine the distribution of patients with different anterior abdominal wall deformities. Physical data, CT and morphological findings were analyzed in 622 patients. The study was conducted in retro- and prospective nature. Five types of deformation were identified depending on anatomical changes of anterior abdominal wall. The first two types included patients without muscular-aponeurotic changes, types 3 and 5a - patients with diastasis recti alone, types 4 and 5b - severe muscular-aponeurotic relaxation due to a combination of diastasis recti and relaxation of lateral abdominal muscles. The principles of distributing patients by anterior abdominal wall deformation were determined for choosing the optimal surgical intervention.
