Zheng Ren silently took a look at the patient’s condition. The general anesthesia was over, and he could be administered at any time. He automatically blocked out the familiar and lucky music and went to wash his hands in silence. People who sang out of tune had no concept of all music. Clear water flowed out of the stainless steel tap, and Zheng Ren entered the system space. At the same time, a crisp ding – Dong sound was heard. [Urgent mission: turning from a cocoon into a butterfly [Mission details: save a patient with abdominal calluses] [Mission reward: 3000 skill points, experience points: 100000 points, energy medicine X2. [Mission time: 15 hours] Eh? Did the pig trotter give him a mission? This was an unexpected surprise, but the reward could only be claimed after the mission was completed, so it was not needed now. Only full – Language proficiency was given in advance. Big pig trotter was very kind in this regard, so Zheng Ren had nothing to complain about. Footsteps could be heard from outside. Zheng Ren guessed that it was director Wei. He opened the system store’s menu and clicked to purchase the surgery time. The system’s operating theater rose from the ground, and Zheng Ren entered it without hesitation. Zheng Ren had nothing to hesitate about as the test subject lay on the operating table. Although he had the [cocoon transformation into a butterfly] mission as a supplement, Zheng Ren, who had experienced a surgery training and was running out of time, was now like a miser, tightly saving every minute and second. On the system’s operating table, the experimental was in a reclining position. The skin was disinfected with iodophor as usual. Sterile towels and large surgical sheets were laid out layer by layer. The incision was made on the right side of the straightened abdominal muscle and entered the abdomen. The incision was about 18 cm long. It was made layer by layer, and the peritoneum was lifted and cut open. This routine sequence also wasted nearly three minutes of Zheng Ren’s time. Feeling a little heartache, Zheng Ren resisted the urge to dissect the experimental body. He was still afraid that if he got used to dissecting, he would show symptoms of split personality. He was a doctor, not a butcher. He cut open the peritoneum, revealing a white patch inside. It was as dense as a layer of oilcloth, and no other structure could be seen. Was abdominal calluses really that serious? Zheng Ren could not believe it. Zheng Ren held the hemostatic forceps in his left hand and used it to pick up a piece of tissue. He used the blunt scissors in his right hand to carefully cut it. Below it … Was not the intestinal tract, but the omentum. Zheng Ren could not understand how many layers were there. The great omentum was supposed to be a barrier that protected the abdominal cavity. However, the great omentum of the experiment subject had lost this function as it was wrapped in layers of cocoons. Like a silkworm baby, it added countless variables to the surgery. It was conceivable that the internal space must also be covered by connective tissue, and there were also layers of connective tissue outside the intestines. Just thinking about it gave him a headache. It was an experimental body anyway. Although Zheng Ren controlled his desire to dissect it, it was not a problem to make a slightly larger incision. When he checked upwards, he found that the gallbladder was large, and there was no congestion or edema in the gallbladder wall. There were no obvious abnormalities in the liver and spleen. It’s good that the higher – ups are fine. If it was combined with diseases such as gallbladder rupture, Zheng Ren would be at a loss. If that were the case, he would probably not have any time left for surgery training. Zheng Ren carefully opened up the dense connective tissue under the greater omentum. There was about 30 ml of a clear, pale yellow liquid in the vesicle cavity, and the aspirator sucked the liquid clean. There were countless such gaps. Zheng Ren didn’t want to think about other things and seized the time to deal with what was in front of him. He examined the intestines and found that the intestinal wall was adhered to the surrounding connective tissue. Blunt scissors and hemostatic forceps were used together, and the separation was done bit by bit and carefully. Even with Zheng Ren’s master level in surgery, it was still very difficult to deal with it without any damage. However, every time he made a mistake, Zheng Ren would remember the difficulty. How much strength should he use? should he use his hands or the blunt scissors? Zheng Ren had also sutured the damaged part. 25 cm away from the ileocephaloid section, the intestinal tract was adhered tightly together. Zheng Ren used a little force and tore the intestine, creating a 2- cm and 3 – cm incision. This part of the intestine was severely swollen and could not be sutured at all. Zheng Ren sighed. This operation had probably failed. He had no choice but to operate roughly and start dissecting the experimental body. As he dissected the patient, he reminded himself that this was a surgery training room, and he was an experimental subject provided by the big pig trotter. If they were outside, they definitely wouldn’t be able to operate so casually. This was something that Zheng Ren had been carefully avoiding. He was really afraid that he would make an irreparable mistake outside on a whim. After an autopsy, Zheng Ren realized that the patient’s intestines were wrapped in countless layers, not only on the outside but also on the inside. The cocoon did not just surround the peritoneum and all of the intestines, it also covered every single one of them. After loosening up a section of the intestine, the connective tissue was still below. In the face of this situation, the best way was to perform colorectal resection, which was a simple and crude way to remove all the parts with serious adhesion. However … Almost all of the test subject’s intestines were wrapped up, and there was no room for Zheng Ren to remove them at all. Even if a patient survived a total intestinal resection, he would need to undergo intravenous hypernutrition for the rest of his life. Most importantly, the patient was already 72 years old, and he could not bear such a serious surgical trauma. It was better to strip it off bit by bit. Although the surgery was difficult, this was the only way Zheng Ren could think of to succeed. Zheng Ren was quite confident in his blunt separation skills, and he also had Dr. Charles’s surgical kit and handy surgical tools. If he couldn’t do it himself, there were only a few people in the world who could. After the dissection, Zheng Ren had a certain understanding of the experimental body’s anatomical structure, so the second operation was much faster. Zheng Ren was extra careful when he went through the position of the previous intestinal rupture. He removed the connective tissue bit by bit and adapted to the strength that the different intestinal walls could accept. The test subject’s intestinal tissue received very little force, and even simple actions such as using hemostatic forceps to clamp down or lift up could cause intestinal damage. Zheng Ren had no choice but to learn from his failures. Different types of instruments were needed to determine how much the wall of the intestine was subjected to. Fortunately, Zheng Ren’s memory had always been good, and with the invisible blessing of the big pig trotter, he could still remember it. After 19 consecutive failures, Zheng Ren finally managed to completely peel off the layers of cocoon membrane. However, Zheng Ren, who was about to place the intestines, suddenly saw that the patient’s ovaries were seriously infected, and they were wrapped tightly. So it was like this! Zheng Ren remembered that the source of abdominal calluses was mentioned in a research paper. It was divided into two types: primary and secondary. Primary abdominal calluses were also known as chronic abdominal calluses. They often occurred in young women in the tropics or subtropics. The reason might be related to fallopian tube infection or gynecological infection caused by reversed menstruation and an autologous immune reaction. The patient had already gone through menopause. However, the infection still came from the ovaries and pelvic cavity, which were the pathogens. What should he do? Zheng Ren was stunned. “Are you going to change to Gynecology next?” He looked at the pelvic cavity and felt a little conflicted.
