What is robotic surgery
In gynecology, robotic surgery represents an advanced form of minimally invasive surgery in which the surgeon operates through a technological platform that transmits the surgeon's hand movements to the surgical instruments with a high degree of precision. It is therefore not "automated" surgery, nor a system that replaces the physician: control of the procedure remains entirely in the hands of the surgeon, who guides every phase of the operation in real time.
In gynecology, robot-assisted surgery is used primarily in complex minimally invasive procedures, both in benign disease and in gynecologic oncology. Its purpose is to facilitate dissection in narrow anatomical spaces, improve visualization of the operative field, and make certain technical maneuvers — such as intracorporeal suturing or dissection of deep anatomical planes — easier to perform.
Open surgery, or laparotomy, involves a larger abdominal incision and provides direct access to pelvic and abdominal organs. Conventional laparoscopy uses small access ports, a camera, and rigid instruments introduced through trocars. Robot-assisted surgery shares the minimally invasive nature of laparoscopy, but differs in offering three-dimensional vision, greater instrument articulation, and a different mode of surgeon control through the console.
How the robotic system works
The robotic system consists of several integrated components that work together during the procedure. The surgical console is the point from which the surgeon controls the operation: from there, the surgeon views the operative field in high-definition three-dimensional vision and operates the controls that transmit movements to the instruments.
The vision tower manages image processing, the light source, and the visualization systems that allow constant control of the operative field. The robotic arms, positioned next to the operating table, support the camera and the surgical instruments introduced through the trocars. Articulated instruments allow more extensive and refined movements than those possible with conventional laparoscopic instrumentation.
Alongside the robotic system, the bedside assistant remains essential: this role supports exposure, suctioning, instrument exchange, and intraoperative needs. The robot does not make autonomous decisions — every movement is initiated, modulated, and controlled by the surgeon in real time, with no decisional autonomy on the part of the platform.
Technical features of the platform
The main technical features of the robotic platform help to explain why this technology can be particularly useful in selected gynecologic and oncologic procedures. High-definition three-dimensional vision provides better depth perception and more accurate identification of anatomical planes. Magnification of the operative field facilitates recognition of vascular, nervous, and lymphatic structures, especially in deep pelvic dissections.
Tremor filtering attenuates involuntary micro-movements and contributes to the stability of the surgical maneuver. Combined with this is motion scaling — the proportional reduction of the surgeon's hand movement at the instrument tip, which can offer an advantage in terms of accuracy during the most delicate steps. Console ergonomics, with seated posture and arm support, can also reduce the surgeon's physical fatigue during long or complex procedures.
A particularly relevant feature is the mobility of the articulated instruments, which reproduce movements similar to those of the human wrist and allow the surgeon to operate with greater freedom in narrow pelvic spaces. This can translate into better triangulation, easier intracorporeal suturing, and greater precision in the dissection of deep anatomical planes. These advantages do not automatically make robotics superior in every procedure, but they explain its usefulness in selected cases of high technical complexity.
When it is indicated in gynecology
The indication for robotic surgery in gynecology does not depend solely on the availability of the technology — it must be defined on the basis of clinical, anatomical, oncologic, and anesthesiologic criteria. The choice of surgical approach must take into account the pathology to be treated, its extent, the patient's characteristics, and the goals of the procedure.
Benign gynecologic disease
In benign disease, robotic surgery may be considered in selected patients undergoing hysterectomy for benign uterine pathology, especially when factors are present that increase the technical complexity of the procedure. It may also be indicated in myomectomy, particularly with multiple or large fibroids, when accurate dissection and complex uterine suturing are required.
Robotics may also be employed in selected cases of deep endometriosis, when the disease involves complex anatomical planes and requires targeted dissection in the pelvis. In carefully evaluated cases, it may be used in the management of selected adnexal masses and in some reconstructive gynecologic procedures, such as sacrocolpopexy or repair of vesicovaginal fistulas.
Gynecologic oncology
In gynecologic oncology, robotic surgery has acquired a defined role above all in endometrial carcinoma, where minimally invasive surgery is the reference approach in many patients. In this setting, the robotic platform may facilitate surgical staging, lymphadenectomy when indicated, and sentinel lymph node identification.
In cervical cancer, the indication must be much more selective, since the surgical approach depends substantially on the type of oncologic procedure required and on available data on oncologic outcomes. In general, the choice between minimally invasive and open surgery must be made on a case-by-case basis, considering the clinical picture, staging, oncologic goals, and multidisciplinary discussion.
Robotic surgery can also be particularly useful in obese patients or in those with complex anatomy, in whom minimal invasiveness can reduce the impact on the abdominal wall and facilitate postoperative recovery, while maintaining adequate technical control of the operative field.
Advantages of robotic surgery
The advantages of robotic surgery must be considered in a balanced way, distinguishing technical from clinical benefits and assessing them within the context of the specific procedure. The available evidence shows more robust benefits in some settings than in others, particularly when robotics is compared with laparotomy or applied to complex cases.
Intraoperative advantages
The main intraoperative advantages include greater precision of movement, better anatomical exposure, and the possibility of working with greater accuracy in deep planes. High-definition three-dimensional vision and greater instrument freedom can facilitate dissection and suturing, especially in technically demanding procedures.
In patients undergoing oncologic surgery for endometrial carcinoma, comparative meta-analyses between robotics and conventional laparoscopy have reported, on average, less blood loss, lower transfusion requirements, and fewer conversions to laparotomy, with an overall consistent perioperative benefit, although of variable magnitude across studies. The advantage over open surgery is even more evident in terms of blood loss, length of stay, and postoperative recovery.
Postoperative advantages
Like other minimally invasive techniques, robotic surgery may be associated with generally lower postoperative pain, earlier mobilization, and shorter hospital stay compared with laparotomy. In many patients, this translates into faster functional recovery and earlier return to daily activities.
The postoperative advantage does not depend on the technology alone, but also on appropriate patient selection, the type of procedure performed, and the experience of the team. For this reason, the benefits must always be interpreted within the specific clinical context.
Advantages in complex cases
One of the settings in which robotics can express its potential is surgery in complex anatomy. The presence of obesity, adhesions, large uteri, deep dissections, or narrow pelvic spaces can make conventional laparoscopy more difficult and increase the rate of conversion to laparotomy.
In these cases, the combination of three-dimensional vision, articulated instruments, motion scaling, and greater stability of the surgical maneuver can favor the execution of minimally invasive procedures that would otherwise be more difficult or less reproducible. Even in this setting, however, the choice must remain guided by clinical appropriateness and not by the mere availability of the platform.
Obese and severely obese patients
Obese patients represent one of the subgroups that may benefit substantially from robotic surgery. Obesity is a known risk factor for major and minor surgical complications, irrespective of the access route. In this context, robot-assisted surgery may offer significant technical and perioperative advantages. A 2016 multicenter retrospective study on 2,300 robot-assisted hysterectomies showed that the robotic cohort more frequently included patients with severe obesity and larger uteri, but presented fewer intraoperative complications compared with laparotomy and the vaginal approach, with shorter hospital stays. Available evidence indicates that robot-assisted surgery may maintain rates of complications similar to or lower than laparoscopy in patients with severe obesity.
Ref.: [2, 3, 4]
Complex gynecologic procedures
The 2023 BJOG Scientific Impact Paper identifies patients undergoing complex gynecologic surgery as one of the groups that may benefit from the robotic approach. The main indications include:
- Myomectomy with multiple or large fibroids
- Sacrocolpopexy for the treatment of vaginal vault prolapse
- Advanced endometriosis with deep, precise dissections
- Tubal reanastomosis in selected cases for fertility restoration
- Repair of vesicovaginal fistulas
Ref.: [1, 5]
Oncologic patients: endometrium and cervix
In endometrial carcinoma, comparative meta-analyses between robotics and laparoscopy report on average less blood loss, lower transfusion requirements, and fewer conversions to laparotomy. The ESGO/ESTRO/ESP guidelines recommend minimally invasive surgery as the primary approach in many high-risk patients as well, while the presence of disease beyond the uterus or cervix represents a relative contraindication.
For early-stage cervical cancer treated with radical hysterectomy, the LACC randomized trial showed worse oncologic outcomes with the minimally invasive approach compared with open surgery, substantially modifying guideline recommendations. The open approach is therefore generally preferred for oncologic radical hysterectomy in cervical cancer, except in highly selected cases discussed in a multidisciplinary setting.
Ref.: [1, 5, 6, 7, 8]
Technical features: motion scaling and instrument articulation
Tremor filtering, while contributing to maneuver stability, does not appear to be the main determinant of precision. A recent review suggests that motion scaling has a greater impact on accuracy, with an estimated improvement of around 20–30%. Robotic articulated instruments typically offer 7 degrees of freedom, allowing more effective triangulation in narrow pelvic spaces, although with the limitation of reduced or absent tactile feedback present on many platforms.
The 2020 ACOG/SGS recommendations indicate that low-complexity cases — such as tubal ligation, simple ovarian cystectomy, bilateral salpingectomy, and diagnostic laparoscopy — do not derive a relevant advantage from the robot-assisted approach.
Ref.: [2, 4]
Limitations of robotic surgery
Robotic surgery also has limitations that must be clearly stated as part of accurate medical information. The first concerns the cost of the technology, which includes platform acquisition, maintenance, dedicated materials, and the organization of the surgical program.
To this are added the setup and docking times of the system, which in some settings may affect organizational efficiency, especially in the early phases of a team's experience. Robotic surgery also requires a dedicated team, a structured training pathway, and an adequate learning curve for both the surgeon and the operating-room personnel.
Robotics is not automatically superior in every procedure. In low-complexity or short-duration cases, the benefit over conventional laparoscopy may be limited or not clinically relevant. Robotic surgery should be considered a useful tool when the indication is appropriate and the potential clinical benefit is concrete — not the best choice in every circumstance.
Safety and patient selection
Patient safety depends first and foremost on appropriate preoperative selection. Evaluation must include the overall clinical picture, the investigations needed in relation to the pathology, prior surgical history, the presence of comorbidities, and a clear definition of the goals of the operation.
In oncology, preoperative staging of disease is an essential element in deciding whether the minimally invasive approach is appropriate. Indications and possible relative contraindications related to anesthesia, pneumoperitoneum, Trendelenburg positioning, or the need for more extensive oncologic procedures must also be considered.
The choice of surgical approach therefore depends on multiple factors: the pathology to be treated, extent of disease, prior surgery, BMI, comorbidities, and oncologic or functional goals. In this pathway, the consultation with the surgeon plays a central role, allowing realistic discussion of expected benefits, limitations, alternatives, and possible risks of the procedure.
Sentinel lymph node and indocyanine green fluorescence
In gynecologic oncology, the sentinel lymph node represents an important step in the staging of certain neoplasms, particularly endometrial carcinoma and, in selected cases, other gynecologic tumors. The principle is to identify the first lymph node — or first lymph nodes — to receive lymphatic drainage from the tumor, in order to evaluate possible metastatic involvement.
Indocyanine green (ICG), a fluorescent tracer, is now frequently used to identify the sentinel lymph node: once injected, it allows visualization of the lymphatic drainage through dedicated optical systems integrated into the robotic platform. Fluorescence facilitates the recognition of lymphatic pathways and sentinel lymph nodes, improving the precision of intraoperative identification.
In selected patients, this strategy may offer advantages compared with systematic lymphadenectomy, reducing the extent of nodal dissection without sacrificing accuracy of staging in the contexts where the indication is appropriate. Here too, the choice must be defined according to guidelines, disease characteristics, and team experience.
Postoperative course
The postoperative course after robotic surgery varies depending on the type of procedure, the underlying pathology, and the patient's clinical condition. In general, the minimally invasive approach allows faster recovery compared with laparotomy, but recovery times must be individualized.
After surgery
In the first hours after the procedure, early mobilization is generally encouraged, as it represents an important element of postoperative recovery. Pain control is modulated according to the procedure performed and the patient's needs. Oral intake is resumed progressively based on the clinical picture and the immediate postoperative course.
The presence of a urinary catheter or drains depends on the type of procedure and the complexity of the operation. In oncologic or reconstructive settings, their management follows specific protocols defined on a case-by-case basis.
Recovery times
Discharge is often earlier than after open surgery, but it depends on the type of procedure and on postoperative clinical stability. Resumption of daily activities, return to work, and resumption of physical activity must also be modulated according to the extent of the procedure and the indications provided by the surgeon.
In many patients, convalescence is shorter compared with laparotomy, but there is no single recovery time valid for every procedure. Functional recovery must be gradual and consistent with the type of surgery performed.
Follow-up
After the operation, a postoperative clinical visit is scheduled to evaluate healing and discuss the outcome of the procedure. In oncology, the histologic result may require a subsequent multidisciplinary discussion to define the possible need for further treatment or follow-up. This step is an integral part of the quality of the care pathway.
Possible risks and complications
As with any surgical procedure, robotic surgery may also be associated with risks and complications, the probability of which varies according to the type of procedure, the pathology, anatomical complexity, and the patient's general condition. Possible complications include bleeding, infection, and injury to adjacent organs such as the urinary tract, bowel, or vascular structures.
Anesthesia-related complications, thromboembolic risk, and the possibility of conversion to laparotomy must also be considered, should intraoperative conditions arise that require a change in surgical strategy. In more complex procedures, specific urinary or bowel complications may also occur.
Accurate preoperative information requires presenting these risks in a balanced way — without alarmism but with clarity — explaining that the individual risk profile always depends on the clinical picture and the planned procedure. The consultation with the surgeon is the appropriate setting to discuss these aspects.
Robotic surgery and laparoscopy: differences
Robotic surgery and traditional laparoscopy are both minimally invasive techniques and share many advantages over open surgery, including smaller incisions, reduced abdominal-wall trauma, and generally faster recovery. They are therefore not opposing techniques but rather different tools within the same minimally invasive philosophy.
Robotics offers ergonomic advantages for the surgeon, three-dimensional vision, and greater instrument articulation — features that can prove useful in complex procedures or in narrow anatomical spaces. Laparoscopy, however, remains a valid, appropriate, and widely used technique in many cases, with established results and excellent efficacy when performed in adequate settings.
The choice between robotics and laparoscopy should not be guided by abstract technological reasoning but by the clinical indication, the complexity of the procedure, the patient's characteristics, and the competence of the surgical team.
Future perspectives
The future perspectives of robotic surgery in gynecology relate to a progressive refinement of clinical indications, the development of more accessible platforms, and broader implementation of structured training programs. A further area of interest is the integration with advanced imaging and intraoperative navigation systems, which could further improve surgical planning and dissection precision in selected settings.
Technological evolution, however, must continue to be accompanied by a critical assessment of available evidence. In gynecology and oncology, progress is truly useful when it translates into a concrete, measurable clinical benefit consistent with the principles of appropriateness, safety, and quality of care.
Frequently asked questions
No. Robotic surgery is neither automated nor autonomous. The surgeon controls every phase of the procedure entirely from the console in real time, initiating, modulating, and managing every single movement. The platform transmits the surgeon's hand movements to the surgical instruments but makes no autonomous decisions.
This distinction is fundamental for a correct understanding of the technology: the surgeon remains the absolute protagonist of the operation, while the robotic system is an advanced precision tool at the surgeon's service.

The main indications in benign gynecology include hysterectomy for complex pathology, myomectomy with multiple or large fibroids, deep endometriosis, sacrocolpopexy, and repair of vesicovaginal fistulas. In gynecologic oncology, the principal role is in endometrial carcinoma, where minimally invasive surgery is the reference approach in many patients.
The indication does not depend solely on the availability of the technology, but must always be defined on the basis of individual clinical, anatomical, and oncologic criteria, evaluated during consultation with the surgeon.
Ref.: [1, 2, 5]
Robotics offers high-definition three-dimensional vision, greater instrument articulation with up to 7 degrees of freedom, motion scaling, and tremor filtering. These features can facilitate dissection in narrow pelvic spaces and intracorporeal suturing, especially in technically complex cases or in patients with unfavorable anatomy.
It should nonetheless be emphasized that traditional laparoscopy remains a valid and consolidated technique for many procedures, and the choice between the two approaches must be based on clinical indication and case complexity, not on the mere availability of the technology.
Ref.: [1, 4, 5]
The main limitations concern the costs of technology and maintenance, system setup and docking times, the need for a dedicated team, and a structured learning curve. On many platforms, tactile feedback is also reduced or absent, which can be a limitation in some procedures.
Clinically, in low-complexity or short-duration procedures, the benefit over conventional laparoscopy may be limited or not clinically relevant, making a less resource-intensive approach preferable.
Ref.: [1, 2, 4]
The sentinel lymph node is the first lymph node — or first lymph nodes — to receive lymphatic drainage from the tumor. Its identification and analysis allows assessment of possible metastatic involvement without resorting systematically to extended lymphadenectomy, reducing the extent of nodal dissection in selected patients.
In robotic surgery, the sentinel lymph node is identified through indocyanine green (ICG), a fluorescent tracer visualized with optical systems integrated into the platform. This technique improves the precision of intraoperative identification of lymphatic drainage. The decision to adopt this strategy must respect guidelines and the specific characteristics of the disease.
Ref.: [1, 5, 6]
The minimally invasive approach generally allows earlier discharge compared with laparotomy and faster functional recovery. There is, however, no single recovery time valid for every procedure: timing varies depending on the type of operation, the pathology treated, the extent of the surgery, and the patient's general condition.
Early mobilization is encouraged within the first postoperative hours. Return to work and resumption of physical activity must be modulated individually according to the surgeon's instructions.
Ref.: [1, 4]
As with any surgical procedure, robotic surgery may carry risks of bleeding, infection, and injury to adjacent organs (urinary tract, bowel, vascular structures). Anesthesia-related complications and thromboembolic risk must also be considered.
Conversion to laparotomy is also a possibility if intraoperative conditions require it. The individual risk profile always depends on the specific clinical picture and the planned procedure: the preoperative consultation with the surgeon is the appropriate setting to discuss these aspects in a personalized way.
Ref.: [1, 4, 5]
Yes, obese patients represent one of the subgroups that may benefit most from robotic surgery. Available data support the safety and feasibility of the robot-assisted approach even in severe obesity, with favorable perioperative outcomes compared with laparotomy, including fewer intraoperative complications and shorter hospital stays.
In this setting, minimal invasiveness reduces abdominal-wall trauma and supports postoperative respiratory recovery — aspects particularly relevant in patients with obesity-associated comorbidities. Each case must, however, be evaluated individually, taking into account the overall clinical picture.
