Background: The application of Deep Learning (DL) in
Minimally Invasive Gynecological Surgery (MIGS) has accelerated rapidly, driven
by the need for enhanced intra-operative navigation, surgical phase
recognition, and predictive analytics. The efficacy of these applications is
fundamentally determined by the underlying neural network architectures, yet a
comprehensive technical synthesis of their comparative performance and clinical
utility in the gynecological context is absent from the literature.
Objective: To provide a comprehensive scoping review
of the DL architectures deployed in MIGS, evaluating their technical
mechanisms, clinical applications, performance metrics, and limitations.
Methods: A scoping review was conducted following
PRISMA-ScR guidelines, drawing from a systematic search of 55 included studies
identified across five major databases. Studies explicitly detailing neural
network architectures applied to gynecological surgical tasks were analyzed,
with a focus on Convolutional Neural Networks (CNNs), Long Short-Term Memory
(LSTM) networks, Deep Neural Networks (DNNs), Transformer architectures, and
hybrid models.
Results: CNNs remain the foundational architecture for
spatial feature extraction in surgical video analysis, achieving accuracy rates
of 85–97% in anatomical landmark identification and instrument detection. LSTM
networks, frequently integrated with CNNs in hybrid architectures,
significantly improve surgical phase recognition by capturing temporal dependencies
across video sequences. Transformer architectures, including Vision Transformers
(ViTs), have demonstrated superior performance in complex multi-modal tasks, outperforming
CNN-LSTM models in surgical workflow understanding. Emerging applications
include augmented reality navigation, automated endometriosis lesion recognition,
and AI-driven prediction of perioperative outcomes.
Conclusion: The DL landscape in MIGS is evolving from
static image analysis toward dynamic, spatio-temporal surgical understanding.
While CNNs and LSTMs constitute the current standard, Transformers represent
the emerging frontier. Critical priorities for future development include model
interpretability, real-time edge deployment, and standardized benchmarking
across diverse gynecological datasets.
