A detalied description of the various manifestation of deep endometriosis should be reflected in classification #Enzian, which requires clinicians to understand the anatomical polymorphism of the disease. The purpose of the work is to explore the types of anatomical polymorphism of deep endometriosis, frequency and options for their combination to determine the main and rare subtypes of the disease. Materials and research methods. Deep endometriosis in 98% of cases is a polymorphic disease with a combination of peritoneal and ovarian endometriosis, and in 91.3% of women it is accompanied by adhesions of the pelvic organs of varying severity; in 2% of patients, deep endometriosis is an isolated form with severe damage to hollow organs; this requires proper preparation for surgical intervention in such patients with the involvement of a multidisciplinary team. Research results. Conclusions. Analysis of the identified subtypes in the future will form the basis for the development of an algorithm for standardized surgical intervention to improve the results of surgical treatment of deep endometriosis.
