The "Iceberg Phenomenon": As Soon as One Technological Problem in NOTES Is Solved, the Next One Appears!

Area of Science:

• Minimally Invasive Surgery
• Medical Engineering
• Gastroenterology

Background:

• Natural orifice transluminal endoscopic surgery (NOTES) remains in its nascent stages despite its proclamation seven years prior.
• Significant technical obstacles impede the widespread adoption and advancement of NOTES procedures.

Purpose of the Study:

• To analyze the primary technical challenges hindering NOTES development.
• To identify and evaluate innovative technological solutions to overcome these identified obstacles.

Main Methods:

• A multidisciplinary team including surgeons, engineers, and industry experts conducted a comprehensive literature review.
• Deficiencies in current NOTES systems were defined, and potential enabling technologies were compiled and assessed based on implementation time and impact.

Main Results:

• Visualization requires enhancement through advanced illumination, mist elimination, image stabilization, 3D stereoscopy, and augmented reality.
• Actuation demands improvement via mechatronic platforms, miniaturized actuators, and intuitive interfaces, supported by real-time depth maps, navigation, and AI systems.

Conclusions:

• Existing and emerging technologies can address most functional deficiencies in NOTES platforms.
• Continuous collaboration between researchers and clinicians is essential for the optimal integration of these technologies.
