This article analyzes results of surgical treatment in 123 patients with concomitant surgical and gynecological diseases, reliant on the anesthetic and operational risks. In early postoperative period, complications arose in patients groups with a significant and high degree of operational and anesthetic risks. Descriptions of risk categories classification allow characterizing the degree of anesthesia risk in surgery. Our study aims to analyze the results of simultaneous surgery for combined diseases of the abdominal cavity and small pelvis, depending on the operational and anesthetic risk. patients underwent a general clinical examination, anamnesis was carefully collected, and a plan for additional examinations was formed, including specialists involvement. Research results showed that at a point that combined operations are controverted with a high degree of anesthetic and operational risk in concurrent operations, these subjects should be scheduled to operate in different stages.
