In operating room No. 8.
Li Zheng's operation continued.
Next is to deal with the hair clumps in the intestines.
Li Zheng started from the pylorus of the stomach and moved down along the intestinal tract little by little.
Found the first hair ball.
"Intestinal forceps." Li Zheng stretched out his hand.
Two intestinal forceps were quickly slapped into his hands.
Li Zheng used intestinal forceps to clamp the intestinal tubes at both ends of the hair ball to prevent the intestinal contents from overflowing and the hair ball from shifting.
Pick up a No. 15 small round knife and prepare to cut.
Chen Dayong immediately stepped on the suction switch and aimed the suction tube at the position where Li Zheng would make the cut.
The intestinal fluid in the small intestine also has a strong digestive effect, so try to avoid leakage.
Li Zheng did not hesitate. He cut the intestinal wall along the long axis of the intestinal tube at the edge of the mesenteric lining, about 5 cm long, slightly larger than the hair ball, to ensure complete removal.
After the incision, the intestinal wall was bleeding, but there were no pulsating bleeding spots, indicating that the blood vessels were not damaged. Li Zheng did not treat the bleeding intestinal wall, and the bleeding would be stopped after suturing it in a while.
After the incision, Li Zheng carefully pulled open the intestine with curved forceps.
A ball of gray-black hair appeared, about 4 cm in diameter.
Li Zheng changed the tissue forceps and carefully picked up the hair ball.
"Fortunately, there is no obvious adhesion!" Chen Dayong looked at it and breathed a sigh of relief.
Li Zheng put the hair ball into the curved plate and checked the intestine again, carefully taking out the remaining hair.
After flushing three times, start suturing the intestinal tube.
The inner mucosal layer was sutured continuously with absorbable sutures.
This time, the inner smooth muscle layer was not sutured separately, but the muscle layer and the outermost serous layer were sutured together.
Guo Weiqiang, who was in the live studio, saw Li Zheng suturing the intestines and frowned, muttering, "That's weird. The intestines are just sutured directly. I really don't understand!"
Zheng Jingjing, who was beside him, turned around and glared at Guo Weiqiang, frowning and saying, "If you don't understand, don't say anything. Ask later. Mumbling to yourself will disturb others from watching the surgery!"
Guo Weiqiang looked at Zheng Jingjing with disdain and said, "You're just pretending. You don't understand it, so you're just watching for fun! If Li Zheng hadn't been performing the surgery, you wouldn't have come to watch it at all."
Zhang Li, the obstetrician and gynecologist, couldn't stand it any longer and said disdainfully, "If you don't have enough knowledge and can't understand it, don't drag others into it. Otherwise, you'll only be embarrassed."
Yang Chuan, who was standing next to him, couldn't bear to watch any longer and laughed softly, "Oh, you're talking as if you can understand."
Zhang Li curled her lips and said, "Of course we can understand!"
"Then tell me, why did Dr. Li suture the smooth muscle layer of the stomach wall separately?"
Although his voice was very low, the leaders in the front row still heard it.
All the leaders turned their heads.
Wu Mingyuan looked at Zhang Li with interest, waiting for her answer.
Zhang Li suddenly became nervous. She didn't expect the leaders to be so interested in this issue, so she quickly organized her words in her mind.
Guo Weiqiang thought Zhang Li couldn't answer and was secretly happy.
Everyone looked at Zhang Li and thought she couldn't answer.
Zhang Li suddenly snorted, "Why? Because she's a minor who's still in her developmental stage. Her stomach still has a lot of room to grow. If you sew the serosal layer and the muscular layer together, there will definitely be a part where the muscular layer and the serosal layer grow together.
After all, the growth rates, toughness, and healing abilities of two different tissues are definitely different. This will lead to larger scars and adhesions in the stomach wound, affecting the stomach's expansion capacity. Eating a little too much may cause stomach discomfort or even stomach cramps.
After hearing her explanation, everyone nodded.
This must be the reason.
Director Wu Mingyuan nodded and smiled, "Not bad. I didn't expect that you, an obstetrician and gynecologist, would know so much about general surgery."
This made Guo Weiqiang and Yang Chuan feel a little embarrassed.
Both of them felt their faces getting hot and smiled awkwardly.
Zhang Li smiled and said, "I haven't finished yet."
"Oh? Go on!" Wu Mingyuan said with a smile. This doctor was quite interesting.
The other leaders also looked at her with a smile.
"Of course, although directly suturing the seromuscular layer may not have a big impact on the stomach, Dr. Li performed the surgery to the extreme, doing his utmost to eliminate the smallest possibility. I can only say that in addition to his superb medical skills, Dr. Li's moral character and art are also admirable!" Zhang Li said seriously.
Everyone nodded, and their understanding of Li Zheng reached a new level.
"As for why the intestine is not sutured in layers, the main reason is that the intestine is too thin. It is not impossible to suture the muscle layer alone, but it is very difficult and time-consuming. Moreover, the intestine is very long, so not suturing it separately will not have much impact." Zhang Li continued to explain.
Everyone nodded continuously.
The questions are explained very clearly.
Guo Weiqiang completely lost his temper and gave a thumbs-up, saying, "I'm so ashamed to have been taught a lesson by an obstetrician and gynecologist today!"
Dean Zhang chuckled and said, "Don't underestimate obstetricians and gynecologists. They have a solid foundation in surgery. Moreover, this involves minors, and they have a good grasp of children's physiological characteristics. You must always remain humble and cautious."
Guo Weiqiang and Yang Chuan both nodded repeatedly.
Director Wu also laughed and said, "When three people walk together, there must be one who can teach me! No matter which department the doctors are from, they all have something to learn!"
Guo Weiqiang felt that he had become the target of everyone's education, but he could only nod and accept it humbly.
"Director Wu is absolutely right. We colleagues must communicate more in the future, learn from each other, and make progress together!" Guo Weiqiang said with a humble smile.
The leaders nodded, very satisfied with Guo Weiqiang's attitude, and turned around to continue watching the operation.
On the screen, Li Zheng continued to pull the intestine downwards.
He kept stroking until he reached a blackened intestinal tube and stopped.
Li Zheng once again clamped the two ends of the blackened intestinal tube with intestinal clamps, and Wang Jiancheng held the intestinal clamps with both hands.
Li Zheng then used a No. 15 small round knife to cut the intestine at the junction of the black and white colors.
It was taken out together with the hair ball in the intestine.
After checking the remaining hair in the intestinal cavity, cleaning it and flushing it several times, Li Zheng then anastomosed the intestinal tract in layers.
Continue to push down.
There was no blackened intestine, but three clumps of hair were found.
Li Zheng used the same method to cut and suture.
Soon, all the hair clumps were removed.
Li Zheng finally checked the intestine from beginning to end to confirm that there were no obvious clumps of hair remaining.
Check the patency of the entire intestinal tract to avoid intestinal stenosis.
I checked the wounds on the stomach and all the intestinal tracts again to make sure they were sutured tightly and there was no bleeding or leakage.
"Flush the abdominal cavity, count the instruments, and prepare to close the abdomen." Li Zheng said.
Zhu Haiping brought out several large steel basins filled with saline solution from the equipment cart.
Repeat flushing the entire abdominal cavity three times.
Li Zheng carefully cleaned up the remaining blood, tissue debris, and contents that might have flowed out of the gastrointestinal tract.
The abdominal cavity was flushed again.
Checked again.
Confirm that there is no problem.
