FAQ
The application of single-port laparoscopic technology in gynecological surgery has achieved significant progress and widespread recognition.
This surgical method enters the human body through an incision and uses the umbilical fold to cover the incision, thereby achieving the effect of "less scars" or "no scars". Compared with traditional multi-port laparoscopic surgery, single-port laparoscopic surgery has the advantages of less trauma, faster postoperative recovery, and shorter hospital stay.
Single-port laparoscopic surgery is mainly performed through the umbilical approach. This method is not only beautiful and invisible, but also reduces the patient's postoperative pain and discomfort. In addition, single-port laparoscopic surgery is also called natural orifice surgery because it can use the body's natural orifice (such as the ) to complete the surgery.
Although single-port laparoscopic surgery has many advantages in gynecology, it also faces some challenges. For example, mutual interference between surgical instruments may make the operation more difficult, requiring higher skills and experience from the operator. In addition, the field of view limitation and "chopstick effect" of single-port laparoscopic surgery are also problems that need to be overcome.
In recent years, many domestic hospitals have begun to widely apply single-port laparoscopy technology and have achieved certain success. For example, the gynecology team of Guangdong Provincial People's Hospital began to vigorously carry out transumbilical single-port laparoscopic surgery in December 2020, and has successfully performed nearly 150 cases so far, and the technology is becoming increasingly mature. In addition, the team led by Professor Shen Yang is also in a leading position in Jiangsu Province and even the country, and has performed a large number of single-port laparoscopic gynecological surgeries.
Single-port laparoscopic technology has broad application prospects in gynecological surgery, especially in the pursuit of minimally invasive and cosmetic effects. However, with the continuous development and improvement of technology, technical and equipment issues in surgical operations need to be further solved in the future to improve the safety and effectiveness of surgery.
Specific application cases of single-port laparoscopic technology in gynecological surgery include the following:
Extensive total hysterectomy and double adnexectomy: On July 12, 2017, Professor Xiong Ying from Sun Yat-sen University Cancer Center led a team to successfully complete a single-port laparoscopic extensive total hysterectomy and double adnexectomy. This marks a new level in the hospital’s minimally invasive gynecological surgery technology.
Giant ovarian cyst + total hysterectomy: On July 25, 2023, the Department of Gynecology of the East Campus of a certain hospital successfully completed the first single-port laparoscopic surgery for giant ovarian cyst and total hysterectomy. The patient, Ms. Li, was 56 years old. The operation was successful and there were no complications.
Transumbilical single-port laparoscopic total hysterectomy: Recently, a hospital's obstetrics and gynecology team successfully performed "transumbilical single-port laparoscopic total hysterectomy" on a middle-aged woman. The operation was smooth and without complications. The patient recovered quickly and was discharged.
Left ovarian cyst surgery: Zhu Jinhu, director of the gynecology department of a hospital, successfully completed a left ovarian cyst surgery using single-port laparoscopy.
Uterine fusion surgery: This patient underwent uterine fusion surgery using single-port laparoscopy combined with hysteroscopy. The surgery is less invasive and has accurate results.
Highly difficult single-port laparoscopic hysterectomy: Through multidisciplinary emergency consultation, the Shanghai United Family Obstetrics and Gynecology team successfully performed a difficult single-port laparoscopic hysterectomy on a 52-year-old foreign patient. The removed uterus weighed approximately 700g. Intraoperative bleeding is less.
A comparative study on the postoperative recovery time between single-port laparoscopic surgery and traditional multi-port laparoscopic surgery showed that the postoperative recovery time of single-port laparoscopic surgery was shorter. Specifically, the skin incision recovery and healing time for single-port laparoscopic surgery is about 6 to 7 days, and patients are discharged from the hospital 3 days after surgery, recover within a week, and can resume normal non-physical work within a month. In addition, patients who undergo single-port laparoscopic surgery can generally return to normal work about one month after surgery.
In contrast, traditional multiport laparoscopic surgery has a longer postoperative recovery time. For example, in some studies, postoperative hospital stays and gastrointestinal function recovery times were longer with traditional multiport laparoscopic surgery than with single-port laparoscopic surgery.
To overcome the visual field limitation and "chopstick effect" problems in single-port laparoscopic surgery, the following methods can be adopted:
Cross-operating mode using bendable instruments: This is one of the main ways to overcome the "chopstick effect". By changing the operating mode of the instruments, the interference between the instruments is reduced, thereby improving the flexibility and safety of the operation.
Reasonable use of electrocoagulation and electrocution instruments: In single-port laparoscopic surgery, rational use of electrocoagulation and electrocution instruments can reduce the number of instruments, thereby reducing the probability of the "chopstick effect". This method can not only reduce interference between instruments, but also effectively control bleeding and maintain a good surgical field of vision.
Adopt multi-angle observation lens: The traditional 0° front-view mirror has a narrow field of view and cannot perform multi-angle observation. Consider using a 30° anterior strabismus lens, which can increase the surgical field of view and reduce operational difficulties caused by limited field of view.
Improvements in technology and devices: Through improvements in technology and devices, such as the application of single-ring devices, rapid identification of key anatomical structures (such as renal pedicles) during surgery, and the use of abdominal wall suspension technology to solve the obstruction of the liver, the efficiency of surgery can be effectively improved. Safety and operability.
Increase or enlarge the incision: When the surgery is difficult, you can consider increasing or enlarging the incision to obtain more operating space and a better view.
Currently, China is in a leading position in the research, development and application of single-port laparoscopic technology. Specifically, Professor Zhang Zhongtao's team from Beijing Friendship Hospital and Professor Sun Dawei's team from Peking Union Medical College Hospital have made significant progress in this field.
Professor Zhang Zhongtao's team completed the first self-developed single-port laparoscopic cholecystectomy in China in May 2008, and made significant progress in the "13th Five-Year Plan" national key research and development plan project.
Professor Sun Dawei's team was the first to carry out single-port laparoscopic surgery in gynecology in China since 2011. It has completed more than 500 surgeries and received support from the National High-Tech Research and Development Plan.
The team led by Professor Xu Kai of Shanghai Jiao Tong University also independently developed the Shurui single-port endoscopic surgical robot and successfully completed a radical prostatectomy.
In addition, the country's first endoscopic single-port surgery system has also been applied in laparoscopic surgery in the Department of Urology.
The main challenges and solutions faced by single-port laparoscopic technology in gynecological surgery are as follows:
Main challenges
In addition, traditional laparoscopic instruments interfere with each other and are difficult to cooperate during single-port surgery, affecting the operation and field of view.
Technical difficulties: Single-port laparoscopic surgery requires highly sophisticated operating skills, especially in fine operations such as suturing.
Limitation of indications: The traditional laparoscopic transumbilical approach is mainly used to complete relatively simple surgeries, such as fallopian tube sterilization, and the indications are relatively limited.
solution
Robotic assistance: The use of robotic manipulators can overcome the shortcomings of traditional endoscopic single-port surgical instruments that interfere with each other and are difficult to coordinate, which affects operation and vision. At the same time, it can help the surgeon avoid the difficulties in traditional single-port surgery.
Multi-access platform: Peking Union Medical College Hospital invented the only single-port laparoscopic dedicated multi-port platform with rotation function, which broke through the technical difficulties of single-port endoscopic suturing, and took the lead in formulating the national expert consensus on single-port laparoscopic surgery in gynecology.
Individualized surgical plan: In clinical practice, after adequate preoperative assessment and strict screening of patients, an individualized surgical plan can be formulated to avoid the need for conversion to multiport laparoscopy during the operation.
Technological Innovation: As technology evolves, new solutions are emerging that allow for more complex surgeries through nearly invisible wounds.
