There are two types of surgeries: one is performed under a clear diagnosis, and the other is to ascertain the true cause, akin to the doctor taking a gamble with the patient against Death God. Due to deteriorating medical environment and worsening doctor-patient relations, most clinical surgeons nowadays dare not even consider the latter, opting instead to stay far away. It’s better not to do it at all than to do it poorly, quickly becoming the standard operating principle for most clinical physicians today.

"Upper thoracoscopy—what if it reveals nothing?" Cao Zhao asked.

God, this man’s questions are devilishly tricky! Pan Shihua’s mind was racing, considering that this bastard’s words seemed to be pushing Student Xie off a cliff.

Duan Sanbao bowed his head, the corners of his mouth seemed to twitch: this is the man’s nature, otherwise, how could he be known as a playful pediatric Boss?

If thoracoscopy reveals nothing, it would be a deadlock.

Xie Wanying’s expression hardened, "I’m sure it will show something."

This confidence level from the little junior sister, don’t be stubborn like a dying duck. Luo Jingming shouted in his heart.

Experienced doctors would never believe her ’misguided confidence’ just because she sounds so confident.

Wrong, what followed was beyond everyone’s expectations.

"I believe you’ll find it, but I also believe you’ll definitely mess up," Cao Zhao said.

The air was filled with dead silence, everyone’s brain froze for a moment.

Immortal Brother’s words truly are like those from a deity; his words may lack Boss Zhang’s sharp tongue but have left many blushing like Zhang’s.

Xie Wanying quickly realized where she had erred, and asked: "Teacher Cao, is the surgery on the ’Ru’ head muscle unable to be done under thoracoscopy?"

Correct, quick thinking, immediately grasping the meaning behind his words. The black whirlpool in Cao Zhao’s eyes flashed with light.

First, it depends on what kind of thoracoscopic surgery it is. So-called thoracoscopic-assisted surgery is not as effective as full thoracoscopy surgery, having a bit of the appearance of hanging dog meat under a sheep’s skin for advertising purposes. True full thoracoscopic heart disease surgeries are rare.

The simplest example: children under three years old who do not meet the weight threshold basically should not expect to undergo any full thoracoscopic heart disease surgery. It should be distinguished here that this specifically refers to heart disease surgeries. Heart surgeries, unlike lung, mediastinum, esophagus, and other thoracic surgeries, must first resolve the extracorporeal circulation issue. With too low a weight, too small of femoral artery and vein diameters, how do you fulfill the needs of extracorporeal circulation? Additionally, once the thoracoscope enters the body, its visibility and operability regarding heart surgery are limited. This causes many types of heart surgeries to be undone, specifically speaking, generally, those heart surgeries that can be done via full thoracoscopy best have an access route from the left atrium or right atrium to resolve.

Take for example this child, if it is truly as you said, the "Ru" head muscle is ruptured.

To solve the rupture of the "Ru" head muscle, the first thing everyone can think of is directly repairing the "Ru" head muscle, which cannot be done deeply within the ventricular wall through full thoracoscopy.

Another approach that might be possible under full thoracoscopy is to abandon the "Ru" head muscle, after all, the "Ru" head muscle has the greatest impact on the mitral valve activity. Simply replace the mitral valve directly with a mechanical valve, we’ve seen before that mechanical valve surgery doesn’t require the "Ru" head muscle’s force. Conveniently, relatively simple mitral valve replacement surgery can be done via full thoracoscopy. However, this means the patient will need lifelong medication, and possibly require a second surgery like that previous patient.

In comparison, certainly, the first choice is to repair the "Ru" head muscle, and full thoracoscopy surgery is therefore ruled out.
