Because of the establishment of the left heart circulation, the repair of the aorta suddenly became much smaller!
Even so, it couldn't conceal Chen Cang's technical prowess during the aortic repair!
This involved a "patching" technique.
The difference might be that this "patch" is a living one!
How ingeniously to combine the artificial blood vessel patch with the aorta's own patch is a skill.
Tao Zi watched Chen Cang choose a No. 4 propylene thread and couldn't help but sigh.
It truly is the daring of those with great mastery; fine thread suturing can indeed increase the tightness during vascular wall suturing, making the aortic wall more robust, but it has higher demands on suturing speed.
However, while Chen Cang was suturing, his thoughts suddenly shifted, and then… he slightly furrowed his brows!
He realized that the suturing of the vessel wall, in terms of speed and tightness, was not the only considerations.
During suturing, how to better match the inner and outer layers of the blood vessel and then enhance the effective function of the vascular wall was very important!
There were also many requirements regarding the tension of the vascular wall, the damage to the intima, the overall recovery ability of the vascular wall, and so on!
Chen Cang couldn't help but fall into deeper contemplation!
The suturing of a major blood vessel, how to choose to achieve the best result?
What issues need to be considered when repairing major blood vessels of the heart…
Thinking of this, Chen Cang couldn't help but sigh.
It was too difficult.
However, this was definitely not an easy task; vascular repair and suturing work had always been under research, just like tendon suturing.
Naturally, this was not something that could be done overnight.
Keep researching slowly!
With this thought, Chen Cang relaxed and continued his work at hand.
Meanwhile, Tao Zi and Zhang Wenfu, seeing Chen Cang , couldn't help but be taken aback; that sigh… it was somewhat poignant!
The type of sigh that carried a faint sadness, mixed with reflections on one's own techniques and a sense of helplessness…
This was clearly dissatisfaction with one's own skills!
The disappointed look was tinged with a trace of pity and reluctance, and the faintly furrowed brow was full of sighs.
This made the cardiac surgery "master and servant" pair watch with twitching eyelids.
Not satisfied with this?
How high must one set the bar for oneself!
Zhang Wenfu looked at the young man and couldn't help but feel touched and slightly ashamed, suddenly reflecting, had he become too complacent over the years?
Why is someone else so outstanding?
Isn't it because of dissatisfaction with oneself?
And his own level of half-full, half-shaken… seemed a bit like coasting through life.
The more Zhang Wenfu thought, the more ashamed he felt.
Tonight, after going back, even if his wife called him, he would have to hold back, lock himself in the study, and read for an hour!
But Tao Zi felt quite content.
Frankly, at his age, because of physical limitations, many techniques were beyond his power, even if he had Chen Cang's insight, he could not perform like Chen Cang.
Because in surgery, after all, it's still about innate talent and physical strength.
This talent includes the skills and natural ability in terms of physical strength!
These things cannot be compensated for by mere effort.
precise and fast suturing, it is not simply achieved by effort, it includes many other factors.
During one operation, three people sighed!
Watching this made Qin Xiaoyuan's heart feel uneasy.
If it's done, it's done; why sigh?
After Chen Cang finished repairing the aorta, he then started to deal with the esophagus.
But the question was, did they really need a PTFE patch?
The fistula in the esophagus was neither large nor small, such that it was possible to use it, but not necessary.
This called for the attending physician to weigh in!
Xiao He, standing by, noticed Chen Cang's hesitation.
If the cut was too large, mattress suturing could be successful, but the scar tissue and the recovery process would undoubtedly affect the function of the esophagus and cause its constriction.
However, the use of a patch would also have side effects!
In this way, Chen Cang was clearly facing a difficult decision.
At this time, how to assess and optimize became extremely important.
Chen Cang's eyes were constantly thinking and judging, considering how to proceed with the operation.
He started to see the surrounding necrotic tissue more clearly with his eyes.
Chen Cang began to remove the rotten and necrotic esophagus!
However, he was very careful and cautious when dissecting and excising, because… he still didn't plan to use a patch, but simply to suture the esophagus.
Xiao He and Tao Zi exchanged glances, both a bit skeptical.
Because at this point, a forced suturing would not be as reliable as using a patch.
Chen Cang's eyes could clearly discern and separate the necrotic tissue, and he tried not to cut too much, but to preserve as much as he could directly.
Soon, the tissue was all cleared away!
At this time, Chen Cang began by first suturing the innermost mucosal layer of the esophagus.
The location of the fistula was right between the first and second narrowings of the esophagus, and Chen Cang's clever mucosal stretching meant the esophagus could now be joined together!
This maneuver immediately impressed everybody!
Xiao He couldn't help but applaud!
The slight angle allowed the constriction to be straightened out without affecting the physiological passage, which undoubtedly became the best choice!
Such a choice was truly genius!
How could such an angle for stretching be conceived?
Now, Xiao He really wanted to ask Chen Cang if he had been using a protractor and a set square during the surgery!
Or did his eyes have a ruler?
Who performs surgery !
And Tao Zi was also taken aback, impressed by the skill of this young man!
Chen Cang didn't relax, because suturing the mucosal layer was just a part, and the internal muscle layer and outer sheath still had to be sutured, all requiring good control of this angle!
The entire operation had undoubtedly evolved from a simple fistula repair to a precision esophageal optimization suturing procedure.
This caused Xiao He, who had long been engaged in esophageal work, to applaud and sing praises!
Though Qin Xiaoyuan didn't understand the surgery very well, watching Chen Cang repair the cut so well impressed him.
Chen Cang's subsequent work was simple, finalizing the operation continuously.
Chen Cang didn't ask for much help from others, because... the system said, the higher the participation, the richer the reward!
This operation, he didn't use a patch when repairing his own esophagus, all done by hand…
The participation should be pretty high, right?
Thinking this, Chen Cang suddenly became eager, wondering if he could get a perfect score?
Counting the gauze... organizing the instruments...
The surgery was about to be completed!
Head nurse Li Ying looked at Chen Cang with a smile in her eyes.
To be honest, she really liked Chen Cang, because this young man... saved on gauze!
Chen Cang's surgeries were probably the most resource-efficient.
Less blood loss, no unnecessary procedures, all of these greatly improved the precision of the surgery.
