Brief Summary: The loco-regional metastatic or non-metastatic status of lymph nodes LN is critical for the therapeutic management of most cancer patients Indeed the presence or absence of lymphatic metastasis is essential for the accurate staging of the disease and strongly influence the prognosis and adjuvant treatment regimens An important revolution in oncological surgery has been the introduction of the concept of sentinel lymph node SLN biopsy to reduce the complications of extensive loco-regional lymphadenectomies SLN identification through ICG- based near-infrared fluorescence NIR cervical injection and its dissection is now recommended by European guidelines to stage uterine malignancies endometrial and cervical cancers However SLN procedures have several limitations In 112 of cases intra- or postoperative complications are reported due to anatomical structures injuries vessels nerves and lymphatic channels disruptions Common mistakes especially when the learning curve is not completed at least 40 procedures include mapping failure 25 and removal of secondthird-level nodes andor empty nodes packets 8-14 Additionally the intraoperative accuracy of frozen section is still far to be adequate with only the 65 of SLN metastasis detection

These limitations are a result of the lack of precision of current SLN localization and analysis as well as of the overall difficulty of visualizing lymph nodes and other critical structures in the retroperitoneum

Currently studies on the safety of surgical procedures are based on perioperative clinical information and postoperative reports written by the surgeons themselves Today videos guiding minimally invasive surgical interventions allow for objective documentation of the procedure and provide opportunities to explore solutions for enhancing safety in the operating room With an increasing use of endoscopic systems across different specialties there is a need for standardization of training assessment testing and sign-off as a competent surgeon in order to improve patient safety In laparoscopic lymph node dissection in endometrial and cervical cancer a standardize stepwise approach to the procedure is highly recommended by identifying key anatomic landmarks and structures in various scenarios that could prevent vascular nervous and ureters injuries and enhance the mapping rate Therefore quantifying and studying intraoperative events such as the rate of achieving the right space dissections and anatomic structures visualization as a recommended step for safety and proficiency would enable the examination of how best to implement guideline recommendations and seek new solutions to reduce operative risks These videos could be utilized to train and validate artificial intelligence AI algorithms with the potential to assist surgeons in the operating room and make the procedures safer Additionally the visual information ICG intensity could hide data that the AI can analyze and correlate with anatomopathological reports By the integration of AI tool with laparoscopicrobotic platform it is possible to enhance MIS video streams in real time with surgical phases detection events recognition ICG signal intensity anatomical structure identification and auto-targeting
Detailed Description: Surgery accounts for approximately two-thirds of all hospital complications About 75 of these complications occur during surgical interventions and half of them are considered preventable Traditionally studies on surgical safety have relied mainly on perioperative information and written reports from the surgical operators themselves Nowadays videos that guide the surgeon during minimally invasive procedures can be easily recorded providing objective documentation of surgical interventions Studying surgical videos and quantifying intraoperative events offer a promising new perspective on the causes of adverse events with the potential to develop solutions for reducing surgical risks and facilitating the implementation of international safety recommendations in surgery

Furthermore recent advancements in Artificial Intelligence AI have shown great success in image understanding raising the possibility of developing algorithms for automatic and large-scale analysis of surgical videos These AI algorithms could also analyze surgical videos in real-time and provide decision support in the operating room

The assessment of lymph node status is of crucial importance in uterine malignancies endometrial and cervical cancer The rate of positive lymph nodes in apparently early stage cancers is far to be low 10 endometrial and cervical 15 Indeed the prognosis and adjuvant treatment regimens are strongly influenced by the presence of nodal involvement Systematic extensive lymphadenectomies are often performed for staging diagnosis of skip metastases and to define the radiation field when adjuvant radiotherapy treatments are required Nevertheless pelvic andor para- aortic lymphadenectomy can lead to significant short-term and long-term complications

What makes the burden of surgical morbidity even more difficult to bear is that in most cases regardless of the type of pelvic malignancy the lymph nodes are free from metastasis This means that the majority of patients undergo an unnecessary risky and burdensome procedure that has no proven impact on their survival To solve this issue in early stage endometrial and cervical cancers evaluation of the sentinel lymph node SLN has acquired a valuable roleThe evaluation of the first lymph node or group of lymph nodes draining the initial lesion and therefore the first station to collect neoplastic cells in case of tumor nodal spread allows node-negative patients to be spared from the surgical comorbidities associated with systematic lymphadenectomy However even if only SLN is removed the rate of surgical complications is still high Capozzi et al reported a 112 complications rate related to intra- operative injuries of vessels nerves and ureters and to post-operative evidence of lymphoceles and lymphedemas due to wrong anatomy dissection and lymphatic channels disruption It is reported a 25 of SLN mapping failure according to patients and cancer characteristics and variability in the surgical steps In 2021 Moloney et al and in 2023 Bizzarri et al published a Delphi consensus for SLN surgical steps in endometrial and cervical cancer to improve the clinical outcomes decrease surgical complications and bias in multicentric prospective trials To date a learning curve of 40 procedures is demonstrated to be needed for successful bilateral mapping Furthermore in some case it is reported the inadvertent failure to harvest nodal tissue in 14 of cases higher rate in obese patients with endometrial cancer with empty packets that may lead to overtreatment for patient safety Sentinel node frozen section analysis tough then is not routinely performed due to its disadvantage in terms of time consumption and not accurate results for micro-metastasis detection 65 of detection accuracy thereby losing part of the techniques potential

In laparoscopic cholecystectomy the critical view of safety CVS has been described to reduce the risk of bile duct injury We aim to adapt concepts of culture of safety to laparoscopic SLN node dissection by identifying key anatomic landmarks and structures in various scenarios that could prevent intra- operative injuries and enhance the mapping rate by following the standardized surgical steps

Therefore quantifying and studying intraoperative events such as the rate of achieving the recommended surgical steps would enable the examination of how best to implement guideline recommendations and seek new solutions to reduce operative risks Furthermore these videos could be utilized to train and validate artificial intelligence AI algorithms with the potential to assist surgeons in the operating room helping in the training to reach faster the learning curve and improve the procedural safety Infact recent AI algorithms capable of automatically assessing and documenting the critical view of safety CVS with short videos could be utilized to support the implementation of guidelines and make laparoscopic SLN dissection safer

Analyzing videos of laparoscopic SLN dissection performed at referral centers could help assess the implementation of a stepwise approach to the procedure and the development of a critical view of safety CVS along with other guideline recommendations as well as develop new solutions for safe laparoscopic SLN dissection The steps to identification and the Critical view of safety are fully described in the study Our project emphasizes the importance of achieving these views of safety before proceeding to the next step of the procedure The next step involves analysing the intensity of the fluorescent signal and correlating it as no-one has ever done with the histological diagnosis of the sentinel lymph node to assess the possibility of correlation between intensity and metastatic nature

Additionally AI algorithms for safe laparoscopic SLN dissection could be tested on the collected videos from multiple hospital centers to adequately study the generalizability of these algorithms before clinical translation

Purposes and objective of the clinical study

The objective of this study is to establish the rate of critical view of safety CVS for safe laparoscopic SLN dissection in a multicentre cohort of surgical videos to reduce complications the surgical learning curve and correlate ICG intensity with the lymph node metastatic nature
