Diametral scale for the classification of the external cervical orifice (D.S.E.C.O.A.A.A.): Proposal of the hysteroscopy unit, Centro Médico Docente la Trinidad

Abstract

Vagino-Hysteroscopy (VH) is a procedure that in its beginnings was associated with pain and complications that forced it to be performed under anesthesia in the operating room. In modern times, the removal of the speculum and Pozzi clamp, VH has become a routine procedure that is carried out in the office on an outpatient basis, favoring the patient's acceptance and tolerance of the study. Objective: To propose a new scale to classify the different types of OCE, calling it the Diametral Scale for the classification of the Alfonso Arias Alvarez External Cervical Orifice (EDOCE AAA) to use it as a routine tool according to the objective anatomical characteristics of its diameter. Method: Retrospective and single-center descriptive observational study, consisting of 129 patients who attended the Hysteroscopy Unit of the CMDLT Gynecology Service to undergo a Vagino-Hysteroscopic evaluation by Dr. Rodrigo Alfonso Arias between the years 2021 to 2022. Results: The EDOCE AAA and the relationship with tolerance to Vagino-Hysteroscopy, good tolerance is reported in 74 patients (57.4%) and with a greater frequency in scale 3, which represents 87 patients (67.4%). The total number of patients with good tolerance and scale 3 is 53 (41.1%). Conclusion: A broader OCE may be associated with better tolerance to Vagino-Hysteroscopy and the proposed scale would serve as a routine tool to standardize medical language among specialists in the field and better planning of patients predicting tolerance or not to the study.
