Objectives: To assess the concordance of the preoperative application of the #ENZIAN classification (#ENZIANi) with the postoperative result (#ENZIANs) using surgical findings as the reference standard. Methods: This retrospective study included 282 consecutive patients with deep endometriosis undergoing surgical treatment. Preoperative assessment with transvaginal sonography and magnetic resonance imaging was compared with postoperative assessment. Concordance and diagnostic test evaluation were calculated. Results: The highest concordance was observed in the F (abdominal wall endometriosis) with k Cohen of 0.837, following the values for pelvic locations, with 0.795 for T left, 0.791 for T right, 0.776 for F (adenomyosis), 0.766 for C (rectum), and 0.75 and 0.72 for O right k and O left, respectively. The highest sensitivity was demonstrated for the P compartment *(98%), T compartment (both sides 97%), and A, B, C (94–96%), corresponding with deep endometriosis. Conclusions: Preoperative assessment using TVS/TAS + MRI with the ENZIANi score correlates well with the ENZIANs postoperative score and demonstrates good concordance in the detection and localization of deep endometriosis, thereby minimizing false negative results and ensuring accurate preoperative staging. The ENZIAN classification is well-suited to surgeon needs and benefits from continuous development. Future improvements, such as adding the expanded C module, may be considered in the next edition.

Objectives: This study aimed to investigate the usefulness and safety of sentinel lymph node (SLN) mapping in comparison to other types of lymph node dissection in patients with uterine corpus cancers. Methods: Retrospective data from 161 patients subjected to uterine corpus cancer staging with SLN mapping with indocyanine green (ICG) dye were collected. Results: SLN procedure was associated with a complication rate of 0%, a median number of dissected lymph nodes of 2 (range 0–13), and a median hospitalization following surgery of 5 (range:2–23) days. Systemic lymphadenectomy and one-sided pelvic lymph node resection were associated with the highest percentage of complications (12% and 25%; p = 0.0030), while the post-surgery course was uneventful for the selective lymphadenectomy group and SLN. Complication rates were the highest in patients with obesity and severe obesity (5.1% and 9.1%, respectively). The number of lymph nodes resected dropped numerically with increasing BMI. Successful ICG injection and SLN mapping were significantly more frequent in SLN procedures. Conclusions: Our study showed that SLN mapping was characterized by a low complication rate and short hospitalization following surgery, and obesity appeared to be related to a higher complication rate. Tailored surgical strategies and individualized patient selection are crucial for the success of SLN mapping; therefore, factors associated with successful SLN mapping with ICG need further exploration.
