The difficulty of the third laparoscopic operation returned to normal levels, and in 20 minutes, Yang Xi solved the battle.

Look at the wall clock on the wall, it's not even 10:20.

Although the operation video has ended, the audience in the live broadcast room refused to disperse, and there was only one purpose to stay, to express their emotions after being shocked.

Looking at the total number of fans that had soared, Yin Wei couldn't help but raise the corners of his mouth, how many fans does Professor Su Dongming Su's Xinglinyuan account have?

The number of fans of the attending doctor of a municipal hospital in a professional website like Xinglinyuan can surpass that of Professor Su Dongming Su, a well-known domestic expert in a provincial hospital, and the corners of Yin Wei's mouth are about to rise to his cheekbones.

Thinking back to a month ago, 'Anesthesia Yin Wei' only had more than 30 poor fans under his name, half of whom were colleagues from this hospital, and the other half were good classmates...... Yin Wei shuddered suddenly, not because it was in a cold state, but because he thought of the danger in the future.

That demon, if you personally set up an account in the Apricot Grove Garden, then do you still have to play by yourself?

No way!

The boy had to be buried in a hole so that he would never jump out of the palm of his hand...... The look conveyed by the corners of Yin Wei's raised mouth changed from smug to hideous in seconds.

......

In the next operating room, a rectal cancer operation is being performed.

There are many types of rectal cancer surgery, such as precancerous resection of the abdomen, combined abdominoperineal resection of the anus sphincter, abdominoperineal combined rectal resection, etc., but in summary, it can be basically divided into anus-preserving surgery and non-anus-preserving surgery. There is also a lot of debate among surgeons about the choice of surgical method, mainly focusing on the close distance between the middle and lower rectal cancer and the anal sphincter, whether the anus and its function should be preserved to ensure the patient's postoperative quality of life, or whether the anus and its function should be abandoned to ensure the thoroughness of the operation.

At present, the definition standard recognized by most doctors is whether the distance between the lower edge of the cancer and the anal margin (dentate line) has reached 7 cm, and if it is more than 7 cm, anus-preserving surgery can be used, and if it is less than 7 cm, it is best to use non-anus-preserving surgery.

The patient Guo Keyuan accepted was just pressed on the 7 cm limit, which made Guo Keyuan very embarrassed. If it is from the wishes of the patient or the patient's family, it must be the pursuit of anus-preserving surgery, and no one is willing to have to pin a fecal bag around their waist all day long.

But what do the patients or their families know?

From a medical point of view, at such a distance, forced anus-preserving surgery is bound to sacrifice the thoroughness of partial surgical resection, and if the surgery cannot completely remove the scope of tumor invasion, then the postoperative tumor recurrence rate is quite high.

Once rectal cancer recurs in situ, the possibility of reoperation is almost zero. Chemotherapy is not sensitive, and radiotherapy cannot be dosed, and at that point, the only option for patients is targeted drugs.

There is no cheap targeted drug, even if it is a generic drug that is more than half cheaper than the third brother, it will cost tens of thousands or even tens of thousands of yuan in a month. Moreover, not all patients can be suitable for targeted drugs, and if the test target is negative, it means that such targeted drugs are basically ineffective for the patient.

Between life and quality of life, Guo Keyuan finally chose life for the patient.

The surgical protocol he developed for this patient was a classic combined abdominal-perineal resection, also known as the Miles procedure. This type of surgery involves a wide range of excisions, including the sigmoid colon and its mesangium, rectum, anal canal, levator ani muscle, ischiorectal fossa tissue, and perianal skin and blood vessels. Although the patient is accompanied by a fecal bag for the rest of his or her life, this surgical procedure is completely resected, with the highest cure rate and the lowest recurrence rate.

This operation is also the most time-consuming and physically demanding of all rectal cancer surgeries, four surgeons have to go on stage at the same time, two people transabdominal incision of the sigmoid colon and rectum, and dissection of pelvic lymph nodes, and the other two people remove the anal canal and levator ani muscle through the perineum, two groups of people will meet in the ischiorectal fossa, and then separate after removing the tissues in the fossa, the upper two people do artificial anus, and the following two people perform perianal excision and seal the anus.

Under normal circumstances, such an operation takes about four hours to complete.

But for Guo Keyuan, he was completely sure that the battle would be resolved within three and a half hours. In other words, the operation starts at 8:30 in the morning, and the operation can be completed at about 12 o'clock in the afternoon, so it will definitely be time to have lunch.

Just when Yang Xi and the others completed the three laparoscopic surgeries planned that morning, the two groups of people on Guo Keyuan's side were preparing to meet in the ischiorectal fossa.

After the removal of the tissue in the ischiorectal fossa, the remaining steps are much simpler, but the removal of the tissue in the ischiorectal fossa is quite careful. The posterior wall is the sacrum, and the vast majority of rectal cancer patients will have presacral venous plexus hyperplasia, if one accidentally touches and breaks, then this operation can not be expected to be completed in three and a half hours, if it is not good, it will not be able to get off the stage in four hours.

Guo Keyuan has completed the Miles technique, and there are 20 sets of Miles, and it should be said that the experience is to be rich.

However......

"What's going on? Where is the bleeding?" When Guo Keyuan muttered these words, his heart was already half cold, and ten seconds ago, when he was bending the pliers, he didn't know what was wrong, and his heart suddenly burst twice, causing his hand to tremble slightly.

It's just a slight shaking, and it shouldn't have touched the presacral venous plexus!

With a fluke mentality, Guo Keyuan wanted to continue to go downward, but at this moment, he saw bleeding in the field.

After observing for a while, Guo Keyuan made a decision, the bleeding is not large, it can be completely put aside, and after the removal of the tissue in the ischiorectal fossa is completed, it will be easier to do hemostasis treatment when he turns back.

Ten minutes later, Guo Keyuan and his assistant completed the removal of the tissue in the ischiorectal fossa, and returned to look for the bleeding point...... The heart that had been half cold was finally cold.

The bleeding point is located between the bone sutures in the sacropotic area, and the bone suture is on the side and back of the sacrum, unless an operation channel is opened from the patient's back, otherwise, from the front treatment, only the bleeding can be seen, but the bleeding point cannot be identified.

There is no choice but to take the stupidest method, stuffing hemostatic gauze and compressing to stop bleeding.

Well, there is no need to think about eating lunch on time, within half an hour, if you can stop the bleeding, you will already be burning high incense.
