Progress in the application of single-port laparoscopic minimally invasive surgery for colorectal cancer

Single-port laparoscopic minimally invasive surgery for colorectal cancer has made significant progress in clinical application in recent years. With the rapid development of laparoscopic technology and the continuous extension of the minimally invasive concept, single-port laparoscopic minimally invasive surgery has received widespread attention and has been carried out in many units. This surgical approach has been widely used in the field of colorectal cancer due to its potential minimally invasive advantages.

Compared with traditional multi-port laparoscopic surgery and open surgery, single-port laparoscopic surgery has the advantages of less trauma and faster recovery. In addition, single-port laparoscopic surgery can further improve cosmetic results and reduce patients' iatrogenic trauma.

Although the application of single-port laparoscopic surgery in the treatment of colorectal cancer is still in its infancy, it has great promise. Fan Yuan believes that in the future, single-port laparoscopy technology will bring new vitality and breakthrough points to minimally invasive colorectal cancer technology.

In short, single-port laparoscopic minimally invasive surgery for colorectal cancer, as an emerging minimally invasive surgical technology, is gradually being used in clinical practice and shows good development prospects. In the future, with the continuous improvement and promotion of technology, single-port laparoscopic surgery is expected to bring good news to more patients with colorectal cancer.

What are the specific technical steps and operating procedures of single-port laparoscopic minimally invasive colorectal cancer surgery?

The specific technical steps and operating procedures of single-port laparoscopic minimally invasive colorectal cancer surgery are as follows:

Preoperative preparation:

Assess the patient's physical condition to ensure that he or she is suitable for single-port laparoscopic surgery.

Carry out necessary imaging examinations, such as CT, MRI, etc., to clarify the location and extent of the tumor.

Surgical approach selection:

The transumbilical single-port laparoscopic surgery technique (TU-LESS) is selected to hide the surgical incision at the umbilicus or around the umbilicus, making use of the natural scars remaining in the human body, so that the operation leaves almost no scars.

Equipment preparation:

Prepare a dedicated multi-access platform for single-port laparoscopy. The platform has a rotation function and can easily perform various operations.
Insert surgical instruments into the abdominal cavity through the umbilicus, including cameras, cutters, sutures, etc.

Surgical procedure:

The umbilical fold wall is used to cover the surgical incision, and intra-abdominal exploration is performed to determine the location of the tumor and the surrounding tissue.

Tumor resection, lymph node dissection and other operations are performed as needed. Since single-port laparoscopic surgical instruments are crowded, special attention must be paid to the coordination of instruments and space utilization during operation.

Use a dedicated multi-access platform for suturing and other delicate operations to ensure surgical precision and safety.

Postoperative treatment:

Observe the patient's postoperative reaction and deal with possible complications in a timely manner.
Postoperative pain management: Since single-port laparoscopic surgery is less invasive, postoperative pain is less severe, but analgesics still need to be used appropriately.

Postoperative recovery:

Promote postoperative recovery, reduce hospitalization time, and improve patients' quality of life.

What are the comparative studies on the therapeutic effects of single-port laparoscopic minimally invasive surgery for colorectal cancer and traditional multi-port laparoscopic surgery?

Comparative research on the therapeutic effects of single-port laparoscopic minimally invasive colorectal cancer surgery and traditional multi-port laparoscopic surgery mainly focuses on the following aspects:

Postoperative pain: Studies have shown that single-port laparoscopic surgery results in less pain 24 hours after surgery than traditional multi-port laparoscopic surgery.

Perioperative conditions and mid-term oncological outcomes: A study using the propensity score matching method found that there were differences in perioperative conditions and mid-term oncological outcomes between single-port laparoscopic surgery and traditional laparoscopic surgery, but the specific data were not listed in detail. 

Feasibility study: Some studies have explored the feasibility of single-port laparoscopic surgery in radical resection of sigmoid colon and rectal cancer, and pointed out that it has certain advantages.

Comprehensive evaluation: The results of the meta-analysis showed that the effectiveness and safety of single-port laparoscopic and traditional multi-port laparoscopic colectomy were compared, and the potential advantages and application value of single-port laparoscopic surgery were discussed.

Single-port laparoscopic minimally invasive colorectal cancer surgery has obvious advantages in terms of postoperative pain, but there is no significant difference in efficacy from traditional multi-port laparoscopic surgery.

What research reports are available on the long-term survival rate and improvement in quality of life after single-port laparoscopic minimally invasive surgery for colorectal cancer?

Regarding the long-term survival rate and improvement in quality of life after single-port laparoscopic minimally invasive surgery for colorectal cancer, there are several research reports:

Zhang Shilin’s research: This study points out that laparoscopic radical resection is effective in the treatment of colorectal cancer, with less trauma, less intraoperative bleeding, faster recovery of gastrointestinal function, significantly shortened hospitalization time, and reduced the incidence of postoperative complications. , the patient’s quality of life was significantly improved.

Cao Jinpeng's study: This study mentioned that the postoperative quality of life of elderly patients treated with single-port laparoscopic rectal cancer surgery has been significantly improved. This demonstrates that single-port laparoscopic surgery has significant advantages in improving patients' quality of life.

Chen Xiaoxun’s study: This study shows that the 5-year survival rate after laparoscopic radical resection of rectal cancer is 81.4%, and it is believed that laparoscopic surgery has the advantage of being minimally invasive and can effectively improve the survival rate of patients.

What current challenges or constraints may affect the development and popularity of single-port laparoscopic minimally invasive surgery for colorectal cancer?

There are currently some challenges and limiting factors that may affect the development and popularization of single-port laparoscopic minimally invasive surgery for colorectal cancer, as follows:

Bleeding control is difficult: Single-port laparoscopic surgery requires minimal bleeding, which places higher demands on the surgeon's skills and experience.

Insufficient learnability and easy promotion: Although surgeons are pursuing the ultimate in laparoscopic minimally invasive technology, they are also gradually paying attention to the learnability and easy promotion of the technology. However, adding an operating hole to the pure single-port surgery , liberating the surgeon's hands and feet, but still needs further optimization and standardization.
