Capítulo 1388: 【1388】Being Tortured
The three-dimensional view is more intuitive, allowing the endoscopy doctor to make subtle adjustments by directly acting without requiring too many layers of thought in the brain.
Interventional surgeons probably need a longer thought process, as fluoroscopy cannot achieve three-dimensional vision. The three-dimensional images produced by the computer system of the angiography machine are reconstructed by the computer, not real-time three-dimensional images, and can only serve as a reference for doctors. It can be said that interventional surgery is quite like semi-blind insertion; without three-dimensional direct view, doctors have to rely on two-dimensional images. However, compared to the usual blind medical operations, it is better as there is at least a picture reference, even if it’s two-dimensional, which significantly shortens the time for remedy and timely adjustment in case of any mistake.
This does not mean that interventional surgery is necessarily inferior to endoscopic surgery; each has its own advantages and disadvantages.
For instance, interventional surgery can achieve things that endoscopic surgery cannot. For example, the endoscope operates as a camera moving inside a lumen and cannot judge the path of the duct system externally.
Some human body ducts are too narrow in diameter and too long in length for an endoscope to meet the required fine diameter and ultra-long length; in such cases, only the X-ray system of interventional surgery can be utilized. This issue was mentioned in the previous bronchoscopy. The cardiovascular system in the human body is similarly ultra-long with a small diameter, so procedures like PCI require an X-ray system rather than an endoscope.
Are there surgeries that combine endoscope and X-ray systems? Yes, there is ERCP, Endoscopic Retrograde Cholangiopancreatography. The duodenoscope is inserted orally into the digestive tract to find the duodenal papilla, and then the contrast catheter is inserted to inject contrast medium for X-ray imaging showing the bile and pancreatic ducts. This is an interventional surgery conducted in the interventional room. The prerequisite remains that the duct should not be too long, too narrow, or too intricate.
Thoracoscopic Coronary Artery Bypass Graft Surgery (CABG) can be performed, but like conventional surgery, it is not a technique solving the pathology from within the body’s duct pathway, and it differs from the aforementioned surgeries. Similar to laparoscopic surgery, the risk is too high and still requires a switch to open thoracotomy.
In this technical analysis, the primary reliance in any surgery is not on the instruments, but on the surgeon. Where instruments have their deficiencies, the surgeon must compensate with their technical skills, much like the endoscopy surgery in the evening.
Xie Wanying, facing the question posed by her senior brother, simply stared back silently.
Facing her clear, brook-like big eyes, Yu Xuexian felt a slight tremor in his heart.
The inference he drew was based on common sense, yet may not apply to her. Just because she’s somewhat unique.
Think about when she was in Hepatobiliary Surgery, without an endoscope or X-ray system, she, along with Song Xueling, successfully performed blind operations.
Currently, the biggest issue doesn’t lie in the technology itself, but—
“Do you think you can handle it alone without Doctor Song?”
This voice did not come from Senior Brother Yu. Xie Wanying turned around, her gaze inadvertently clashing with those cold, seemingly emotionless black eyes across from her, sending a slight shiver through her heart.
It was Fu Xinheng asking her the question; his gaze swept over every slight expression on her face like a second hand, with an absolute scrupulousness, not overlooking even the slightest academic hesitation deep inside anyone.
Even the smallest uncertainty in technology could be precisely captured by his icy eyes.
In cautiousness, Xie Wanying immediately closed her mouth.
Teacher Fu, unlike others, only talks about technicalities, all hard currency, so not a single word can be wasted.
