China News Service, Shanghai, February 28 (Chen Jing and Wang Genhua) With the continuous development of medical technology, experts use robotic surgery to benefit patients with the advantages of ultra-precision, minimally invasive and rapid recovery, and restore hope for their lives.

　　The reporter learned on the 28th that the tumor in the rectum of a 55-year-old Ms. Wang (pseudonym) from Fujian has grown wildly and spread to the uterus, bilateral appendages and left ureter. If it is allowed to continue to grow, her life will be in danger.

Experts from the Department of Anorectal Surgery, Department of Urology, Department of Anesthesiology and other departments of the Second Affiliated Hospital of Naval Medical University (Shanghai Changzheng Hospital) worked together to successfully perform an ultra-difficult "combined pelvic organ resection" with the assistance of robots.

　　Associate Professor Yao Houshan of the Anorectal Surgery Department of Shanghai Changzheng Hospital said in an interview that day that the tumor "spread" in Ms. Wang's body like a bunch of grapes. The condition is quite complicated. The lesions are located deep in the pelvic cavity and are adjacent to each other. It is difficult to expose the field of view and difficult to perform radical resection. Very big.

On the premise of radical tumor cure, how to maximize the patient's organ function and reduce postoperative complications requires ultra-precise, minimally invasive and efficient surgical solutions.

Yao Houshan organized a multidisciplinary joint discussion and consultation to comprehensively evaluate and make decisions.

　　Ms. Wang told reporters that she received chemotherapy, but her intestinal obstruction symptoms gradually worsened, she was unable to eat, and her health deteriorated.

After receiving the diagnosis, experts in Shanghai provided preliminary treatment, and his overall condition improved significantly.

Yao Houshan said that preoperative imaging examination showed that Ms. Wang’s rectal lesions infiltrated the cervix and left ureter. To completely remove the lesions, the rectum, uterus, bilateral appendages and part of the ureter needed to be resected simultaneously; after the resection was completed, the digestive tract also needed to be reconstructed. and urinary system.

　　Da Vinci Robot Xi is an intelligent endoscopic minimally invasive surgery system in the field of surgery. It has great advantages in visual field and digestive tract reconstruction for combined pelvic organ resection of locally advanced rectal cancer. It not only has less surgical trauma and less bleeding , more accurate.

It is reported that during the operation, Associate Professor Yao Houshan from the Department of Anorectal Surgery and Professor Chen Ming from the Department of Urology, the two surgeons, flexibly controlled the robotic arm and used skilled and superb surgical skills to remove the tumor smoothly and thoroughly clean up the regional lymph nodes.

They used 3D high-definition images to perform precise operations to preserve the pelvic nerves to the greatest extent and achieve functional protection; the patient's blood loss was only 100 ml, and the surgical incision was 8cm.

Doctors also successfully completed primary sigmoid colon-rectum anastomosis and left ureter-bladder reimplantation reconstruction.

On the second day after the operation, Ms. Wang was able to move around freely.

　　Yao Houshan said that the postoperative pathology report showed that there was no tumor residue on all resection margins and the tumor lesions were completely removed.

What's even more gratifying is that although Ms. Wang's tumor was locally advanced, it did not have lymph node metastasis or vascular or nerve invasion, and the stage was still early to mid-stage.

In this way, her 5-year survival rate can reach 60% to 80%.

Associate Professor Yao Houshan said that the development of medical technology and the improvement of surgical techniques, combined with reasonable drug treatment, rehabilitation management, etc., can reverse or even cure the condition of those patients who were originally very difficult, so that the quality of life of patients can be improved and their survival period can be extended.
