Comparison of perioperative outcomes between conventional laparoscopy and robotic-assisted surgery in the surgical treatment of endometriosis: a retrospective study
This retrospective study of 520 patients at a high-volume tertiary center found that while both robotic-assisted and conventional laparoscopic surgeries for endometriosis share similar safety profiles, robotic surgery offers superior perioperative efficiency with shorter operative times, anesthetic durations, and hospital stays.

Endometriosis is a common condition where tissue similar to the lining of the uterus grows outside the uterus, causing chronic pain and other complications. For many women, the most effective way to manage this disease is through surgery to remove the misplaced tissue. The gold standard for this procedure has long been laparoscopy, a technique where surgeons make small incisions and use long, thin instruments to operate while viewing the inside of the body on a screen. More recently, a newer approach called robotic-assisted surgery has emerged. In this method, a surgeon controls robotic arms from a console, which offer three-dimensional vision and instruments that can move with greater flexibility than the human hand. While both methods are minimally invasive, meaning they avoid large cuts and allow for faster recovery than traditional open surgery, doctors have debated whether the robotic approach truly offers better results or if it simply takes longer and costs more.
A team of researchers at Einstein Hospital Israelita in Brazil set out to settle this question by looking back at the records of 520 women who underwent surgery for endometriosis between 2018 and 2022. They divided these patients into two equal groups: one group received the traditional laparoscopic surgery, and the other received the robotic-assisted procedure. The researchers wanted to see if the choice of technology changed the time spent in the operating room, the length of the hospital stay, or the risk of complications. They examined details such as how long the surgery lasted, how much blood was lost, whether patients needed to go to the intensive care unit, and if anyone had to be readmitted to the hospital shortly after leaving.
The study revealed a surprising shift in the expected timeline of these procedures. For years, it was widely believed that robotic surgery took longer than standard laparoscopy, largely because of the time needed to set up the robot and attach it to the patient. However, in this high-volume hospital where the surgical team had years of experience with the technology, the opposite was true. The women who underwent robotic surgery had their operations completed in an average of 137 minutes, while those with traditional laparoscopy took an average of 153 minutes. The total time spent under anesthesia was also shorter for the robotic group, averaging 178 minutes compared to 201 minutes for the other group. Furthermore, patients who had the robotic procedure left the hospital sooner, staying for an average of 39 hours, whereas the traditional laparoscopy group stayed for about 50 hours.
Despite these differences in speed and efficiency, the safety of both methods remained identical. The researchers found no significant difference between the two groups regarding complications during surgery, the need for blood transfusions, or the rate of conversion to open surgery. In fact, conversion to open surgery was extremely rare, occurring in only one patient in the traditional group and none in the robotic group. The rate of readmission to the hospital shortly after discharge was also similar, affecting about 5 percent of the traditional group and 3 percent of the robotic group. The study suggests that once a medical center has fully mastered the use of robotic technology, the procedure becomes not only safer in terms of patient comfort and recovery speed but also faster than the traditional method.
The authors note that these results are specific to a center with a mature and experienced robotic program. In the early days of adopting such technology, or in hospitals with less experience, the setup time might still make robotic surgery slower. However, for this specific group of patients and surgeons, the robotic approach proved to be a highly efficient alternative that did not compromise safety. The study concludes that while both methods are safe and effective for treating endometriosis, the robotic system offers a distinct advantage in speed and hospital stay when performed by an experienced team. This finding challenges the old assumption that robotic surgery is inherently slower, suggesting that with enough practice, the technology can streamline the entire surgical process for the benefit of the patient.
