A robotic surgical system can provide a surgeon with a better view, greater instrument movement and a level of control that conventional instruments cannot always offer. What it cannot provide is surgical judgment. That remains with the person sitting at the console, deciding where to dissect, what to preserve, how to approach difficult anatomy and how to respond when the procedure takes an unexpected turn.
This distinction is becoming increasingly relevant as robotic surgery finds a place across complex gastrointestinal, colorectal, urological, gynaecological, thoracic and abdominal procedures. The technology has changed what surgeons can do through minimally invasive access. The quality of the surgery still depends heavily on who is using it.
The robot is a surgical tool
Robotic surgery is sometimes described in terms of the machine itself. In practice, the system is an extension of the surgeon’s hands and eyes.
The surgeon controls the instruments throughout the procedure. Besides a three-dimensional view with magnification to aid in the identification of anatomical structures, articulated instruments provide controlled movements within confined spaces. Such capabilities are especially useful when an operation involves delicate dissection or reconstruction.
The technology can make certain tasks easier to execute. It does not decide which tissue should be removed, which structure should be preserved or how a complication should be managed. Those decisions come from surgical training and experience.
Experience shapes the learning curve
Robotic surgery has its own learning curve. A systematic review published in BJS Open examined learning curves across 10 surgical specialties and found substantial variation between procedures and surgeons. Previous experience also appeared to influence how quickly surgeons progressed through the learning process.
There is no single number of procedures that makes a surgeon an expert. A straightforward procedure and a technically demanding cancer operation can require very different levels of experience. The learning process also changes as surgeons move from routine cases to more difficult anatomy and complex patient profiles.
This is why the number of robotic procedures performed is useful information, but it is only one part of the picture. Training, experience in conventional minimally invasive surgery, understanding of anatomy, case selection and the ability to manage complications all contribute to surgical proficiency.
Complex cases test the surgeon
Robotic technology becomes particularly valuable when the anatomy is difficult to access or when precision is required around important structures. These are also the situations where surgical judgment becomes especially important.
A surgeon may begin a procedure expecting one set of anatomical conditions and encounter something different once inside the body. Previous surgery can create adhesions. Tumours can involve surrounding tissue. Inflammation can obscure normal anatomical planes. Bleeding can change the situation within seconds.
The robotic platform can provide excellent visualisation and instrument control in such circumstances. The surgeon has to interpret what is on the screen and decide what to do next. That is where experience becomes visible.
Case selection is part of surgical expertise
Good robotic surgery begins before the patient enters the operating room. Not every patient or procedure is automatically suited to a robotic approach. The surgeon has to assess the diagnosis, previous surgical history, anatomy, medical conditions and complexity of the planned procedure before recommending the most appropriate technique.
A surgeon who has experience across robotic, laparoscopic and open procedures can evaluate these options more broadly. The objective is to select the approach that offers the most appropriate balance of safety, technical feasibility and expected outcome for the individual patient.
This is also why robotic surgery should be viewed as part of a complete surgical programme rather than as a standalone technology.
Volume matters, but so does the right kind of experience
Research across surgery has consistently examined the relationship between experience and outcomes. A large systematic review covering more than one million cases found that increased case volume was associated with improved health outcomes in the majority of the studies reviewed.
For robotic surgery, volume needs context. A surgeon performing a high number of routine procedures may have a different experience profile from one regularly managing complex revisions, advanced gastrointestinal surgery or difficult abdominal cases.
Experience with the specific procedure matters. Experience with the robotic platform matters. So does experience in managing the complications that can arise during that procedure.
For patients, understanding this distinction can be more useful than simply asking whether a hospital has a robotic system.
Training goes beyond operating on patients
Robotic proficiency is built through structured training, simulation, mentorship and supervised clinical experience. Recent research on robotic surgical training has found that simulation-based programmes can improve technical performance, task completion and error rates, with expert feedback helping accelerate skill development.
Mentorship also has a role, particularly when surgeons begin performing technically demanding robotic procedures. A 2025 systematic review and meta-analysis of robotic pancreatic surgery found that formal mentoring was associated with shorter learning curves and improved operative outcomes during the transition to proficiency.
The operating room, therefore, is just a piece of the puzzle to become a competent robotic surgeon. Training continues with case review, academic involvement, peer discussion and exposure to more complex cases.
Technology will keep advancing
Robotic platforms are becoming more sophisticated, with developments in imaging, digital planning, data analysis and artificial intelligence likely to add further capabilities. These tools may provide surgeons with more information during an operation and help with planning complex procedures.
Yet the basic principle will remain the same. Better technology creates better possibilities. It does not remove the need for clinical judgment.
For patients considering robotic surgery, the relevant questions extend beyond which robotic system a hospital owns. The surgeon’s experience with the procedure, familiarity with the technology, volume of relevant cases and approach to complex situations are equally important.
Robotic surgery has changed the technical possibilities of minimally invasive treatment. The surgeon still determines how those possibilities are used. In complex procedures, that combination of advanced technology and deep surgical expertise is what ultimately defines the quality of care.
