The authors present a retrospective clinical study done on a 13-pacients basis diagnosed during surgery with acute necrotizing enteritis. This study follows the complexity of pathogenic factors and the difficulties one confronts with when establishing a diagnosis since the clinical manifestations are non-specifical and shows the contribution of laboratory data to an earliest possible diagnosis. Both medical and surgical treatment are analyzed depending on the results achieved with an attempt to determine a therapeutic approach as beneficial as possible, aiming at making clear either enterectomy or a conservatory surgical decision should be made. Mortality rate under such therapeutical approach was 38%.
