ABSTRACT
PURPOSE: The objective of this study was to evaluate and compare the diagnostic performance of ultrasonography (USG) assessment using structured reporting with intraoperative laparoscopic assessment in deep infiltrating endometriosis (DIE) using the recent update of the #ENZIAN classification. METHODS: This was a retrospective study conducted in Tertiary Multi-disciplinary Endometriosis Care Hospital over a period of 8 months which included 50 patients who underwent a planned laparoscopic endometriosis excisional surgery after a dedicated USG assessment using International Deep Endometriosis Analysis (IDEA) protocol and #ENZIAN score (updated ENZIAN classification), between Feb 2021 and Sept 2021 at Apollo Hospitals, Hyderabad. The pre-operative USG findings were reported in a structured reporting format and intraoperative findings were classified using the standard #ENZIAN classification. No prospective interventions were done. A review of pre-operative ultrasound and laparoscopic findings as per the #ENZIAN was done. RESULTS: Sensitivity and the negative predictive value of ultrasound were 86% and 84.2% for peritoneal lesions, 97% and 93.3% for left ovarian lesions, 93% and 91.6% for right ovarian lesions, 91% and 84% for left tubal lesions, 90% and 86.3% for right tubal lesions, 93% and 75% for uterosacral ligaments, 93.3% and 97% for rectal lesions and sensitivity and negative predictive values were 100% for rectovaginal lesions, adenomyosis, and ureteric lesions as confirmed on laparoscopy. CONCLUSION: Dynamic ultrasound assessment with a structured report based on IDEA protocol and #ENZIAN score is accurate for mapping of pelvic endometriosis in all forms, and it correlates with laparoscopic findings, thus helps surgeon for better planning and providing a road map for surgeons. From a clinical perspective, a uniform and shared reporting system across imaging and therapeutic modalities will simplify communication, improving patient management by conservative or surgical treatments, avoiding multiple repeat surgeries, and improving quality of treatment.
