With the rapid development of laparoscopic gastrointestinal surgery, laparoscopic surgery in many hospitals at home and abroad has accounted for more than 70% of all gastrointestinal surgeries, and the use of laparoscopy for colorectal disease surgery has become the gold standard, and the level of minimally invasive surgery has become an important symbol to measure the overall level of a hospital. It has been described as one of the directions of the development of surgical medicine in the 21st century. Two patients who were prescribed three years ago for difficult laparoscopic radical rectal cancer recently came for follow-up consultation and recovered quite well, and no recurrence or metastasis of tumor was found after the review, so I couldn’t help but feel very relieved that laparoscopic technology has brought the gospel to the common people. A male patient, who had undergone open surgery for colon cancer in our hospital a few years ago, was later found to be suffering from rectal cancer during physical examination, and the huge trauma and pain of open surgery once made him want to give up further treatment. Although the patient with a history of surgery had heavy abdominal adhesions and was difficult to operate, we successfully completed the first laparoscopic surgery for recurrent colorectal cancer in Taizhou, creating another first in the region and correcting the misconception that patients with a history of surgery cannot use laparoscopic surgery, reflecting our superior technology and determination to challenge high difficulties. Another case of an old woman with rectal cancer had been seen in many hospitals, and all doctors said that the anus could not be preserved because of the low location of the tumor. Considering that laparoscopic surgery has a clear view, relatively large operation space, and the use of special instruments, which can be separated to a lower level, and that there have been reports of anal preservation at home and abroad, which is another major advantage of laparoscopic surgery, we decided to perform laparoscopic ultra-low anus preserving radical surgery for the patient. The patient recovered very well after the operation, and his wish for anus preservation was realized. Laparoscopic surgery was able to preserve the anus that could not be preserved by traditional surgical methods, which improved the patient’s quality of life. Compared with traditional open surgery, laparoscopic gastrointestinal surgery has the advantages of less intraoperative bleeding, clear vision, smaller incision, less postoperative pain, faster recovery of gastrointestinal function, shorter hospital stay, and less impact on the immune function of the patient’s body.
