To systematically evaluate the awareness, acceptance, and clinical dissemination status of the super minimally invasive surgery (SMIS) concept among senior experts in the digestive field in China, and to provide evidence-based support for its systematic promotion.

A cross-sectional questionnaire survey was conducted from June to July 2025 using purposive sampling among senior experts in the digestive field across 31 provincial-level administrative regions in China.

The awareness rates of the core SMIS concepts (definition, goal, principle) all exceeded 98%, and over 97% of the experts endorsed its value orientation.The implementation of SMIS techniques showed significant gradient differences: the application rate of natural orifice non-full-thickness resection was the highest (87.2%), while that of puncture channel techniques was the lowest (37.3%).Significant differences were observed in theoretical exposure and implementation of complex techniques across hospitals of different levels (P<0.001), whereas awareness of the core concepts remained highly consistent across different departments and professional titles (P>0.05). Inconsistent medical insurance payment policies were identified as the primary barrier to promotion, and 88.6% of the experts called for the establishment of standardized training courses. Notably, 99.7% of the experts expressed willingness to continue advancing SMIS-related clinical work.

The SMIS concept has gained broad awareness and strong acceptance among senior experts in the digestive field. However, its clinical dissemination faces multiple challenges, including technical complexity, medical insurance policies, training systems, and multidisciplinary collaboration.A systematic promotion strategy is urgently needed to facilitate the translation of SMIS from theoretical consensus to widespread clinical practice.
