21st Century Necromancer

Under the combined efforts of Chen Yu and everyone else in the operating room, the child lying on the operating table finally was out of danger.

Although the situation was critical at one point during the surgery, with Chen Yu, the leading surgeon, insisting and the cooperation of the other doctors, they still managed to save the child’s liver and dealt with the other issues.

The entire surgery lasted a full eleven hours. Chen Yu cleared the bleeding in the child’s lungs and also sutured his ruptured spleen back together. As for the liver, which was too difficult to handle, Chen Yu used cryotherapy to temporarily stop the bleeding and then sutured the abdomen.

Cryotherapy is a novel surgical technique based on the Joule-Thomson principle, also known as the gas throttling effect. Originally it was a new technique used in tumor treatment. The main treatment principle is to rapidly form ice crystals inside and outside the cells upon cooling, causing tumor cells to dehydrate and rupture. At the same time, freezing causes vasoconstriction, slowing down blood flow, and blocking blood flow through the formation of microthrombi, leading to ischemic necrosis of tumor tissue. Tumor cells rupture and cell membranes dissolve after repeated freeze-thaw cycles, promoting the release of antigens that are hidden and stimulating the body to produce antibodies, enhancing immune capability.

Chen Yu applied this technique to the treatment of a patient’s shattered liver, aiming to utilize cryotherapy’s ability to slow blood flow and stimulate the formation of microthrombi to stop the bleeding.

Although the surgery was really difficult, and besides the liver, the spleen was even harder to deal with. Though the damage was less severe than the liver’s, the spleen was more fragile and challenging to suture. Normally, the spleen is an organ that can be dispensed with, but Chen Yu still repaired the blood vessels of the remaining spleen after removing the portion that was too severely damaged, preserving the remaining spleen, and addressed all other organ damage apart from the liver.

"Professor Chen Yu, I don’t quite understand. We can say preserving the liver is for the child’s future benefit, but isn’t the spleen an organ that can be done without? Why go through such a difficult procedure to preserve the spleen and keep it?" Having temporarily sutured up the patient’s abdominal cavity and concluded the surgery, the pediatric associate professor, who had just handed over the final suturing to Doctor Higashiyama, asked Chen Yu curiously.

During the surgery, when every second counted, it wasn’t suitable to raise any concerns, but now that the surgery was over, this pediatric associate professor naturally voiced his question.

After all, in normal circumstances, a ruptured spleen is dealt with by a direct removal, not by going through the trouble to preserve it like Chen Yu did.

"The spleen is the body’s blood reservoir and an important immune organ. Both the mononuclear cells stored in the spleen and the immunoglobulins it produces are very important components of the body’s immune functions. The child’s liver was severely damaged. If we were to remove his spleen as well at that time, it would have a significant impact on his future bodily immune functions," Chen Yu finally had the mood to explain his reasons to the pediatric associate professor: "Although many organs in the human body have overlapping functions and removing certain organs doesn’t cause the body to lose a specific function, the balance within the body is also very fragile. The long-term impact of a reduction in certain functions is something we must consider. This patient is still a child, and we can’t just abandon his future healthy life because we find the surgery too bothersome."

The pediatric associate professor listened to Chen Yu’s explanation and couldn’t help but widen his eyes, seemingly feeling that Chen Yu’s figure under the operating light was so dazzling. Wanting to express his admiration but not knowing what to say, in the end, he bowed deeply to Chen Yu and said, "You’ve worked hard!"

"You’ve worked hard too." Chen Yu smiled and didn’t mind it, glanced at the other people in the operating room, then looked at Jounouchi Hiromi, who was smiling at him. He said "Thank you everyone for your hard work," and then left the operating room.

By the time Chen Yu exited the operating room, Daimon Michiko had also finished her surgery and was in the process of removing her bloodstained disposable surgical gown.

"Daimon-san, you’re done with your surgery too? What’s the situation with your patient?" Chen Yu removed his surgical gloves and his own gown, curiosity in his voice as he asked Daimon Michiko.

"The patient I dealt with had rib fractures and a punctured heart, so it took quite a bit of time." Daimon Michiko raised an eyebrow, seemingly surprised that Chen Yu’s surgery had also taken so long, "What happened on your end that it took so much time?"

After tossing his gown into the designated waste bin and moving to wash his hands at the sink, Chen Yu casually replied, "The victim had hemopericardium, hemothorax and hemoperitoneum, bleeding in the lungs, and a ruptured spleen and liver. Although none of the issues were particularly dangerous, they were quite complex to deal with, hence the time it took."

"Ruptured spleen and liver? So, Doctor Chen Yu, did you perform spleen and liver salvage then?" With Chen Yu’s briefing and considering the time he spent in surgery, Daimon Michiko easily inferred the choices Chen Yu had made.

"The spleen was preserved, but the liver was too badly shattered. Right now, I’ve just used cryopreservation to control the damage to his liver. Whether we can save it or not will depend on how smoothly tomorrow’s surgery goes." Thinking about the child’s liver, which was nearly split in half, Chen Yu couldn’t help but sense the difficulty of the problem.

Though he was capable of handling such injuries, being able to handle them didn’t necessarily mean being able to cure them. With the severity of the child’s condition, even Chen Yu wasn’t confident about stitching the entire liver back together.

With this in mind, Chen Yu couldn’t help but turn to Daimon Michiko, "Daimon-san, are you skilled in liver suturing? I want you to assist me with this child’s liver suturing operation tomorrow."

"Liver suturing? The child’s liver is shattered to the extent that you need to use cryopreservation to temporarily close the abdominal cavity and only perform the surgery tomorrow?" Daimon Michiko’s eyes widened as she looked at Chen Yu. Being someone whose interest was in surgeries, such a challenging operation was exactly what intrigued her, "How about letting me take the lead tomorrow?"

"Sorry, I must decline," Chen Yu said with a smile, denying her enthusiastic wish to be the lead surgeon, "However, Daimon-san, if you’re willing to be the assistant, that’s still possible."
