The patients diagnosis was displayed in the upper right corner of Zheng Rens visionchronic cholecystitis.

Zheng Rens heart sank immediately as this was clearly a complication of acute food poisoning.

The risk of complications would be minimized if the patient underwent an intravenous infusion of antibiotics for one week, but antibiotic misuse by idiotic doctors had become a trend in the country these days.

There were indeed idiots among doctors. For example, there was the usage of triple-drug therapyincluding quinolone, which was metabolized by the kidneyas postoperative prophylactic antibiotics in an underaged patient with an uncomplicated appendicitis case.

The vast majority of doctors had good intentions, and they placed disease treatment and saving patients lives as their top priorities.

However, their intentions were usually and ruthlessly destroyed in reality.

Veterinarians in charge of the medical industry had issued regulations to restrict the clinical usage of antibiotics. Their prescription was justified only when the patient exhibited signs of pyrexia, positive bacterial culture, derangement in routine blood investigations and so on.

However, only a few people knew that meat and milk actually contained a large amount of antibiotics from animal husbandry. Even producers had no choice. How could they meet the increasing demands of the market if they stopped using antibiotics and production fell?

Would they force everyone to be a vegetarian? Zheng Ren would be the first to disagree as he was very fond of eating meat skewers.

This was a troublesome issue and there was nothing Zheng Ren could do about it.

It was good enough if he could manage the emergency department in Sea City General Hospital.

Do an emergency bedside B-scan ultrasonography. Im guessing that he has cholecystitis. Zheng Ren quickly made a diagnosis.

Chief Zheng, how did he get cholecystitis when he was previously well? asked the patients son in distress.

I told you, an acute toxic liver injury will result in exudation and the exudate has a chance of accumulating around the gallbladder. Physical function declines with age, and constant stimulation for one week can lead to cholecystitis, Zheng Ren explained.

However, this type of cholecystitis was uncommon. In fact, its risk was less than 10 percent.

Luck was the predominant factor in this issue. Obviously, it had not been on this patients side.

It was inappropriate to discuss bad luck with the patient and his family members. Zheng Ren was indeed insensible, but that was limited only to women. He was still emotionally mature and was a smooth talker around patients.

This elderly man had the honor of becoming the first patient of the emergency ward.

His B-scan ultrasound showed that his gallbladder was 95x47mm in size, with marked asymmetry in its wall and striated thickening at 3mm. The gallbladder wall had normal echogenicity with echogenic debris noted within the gallbladder itself.

The ultrasound report concluded that he was indeed suffering from late-onset chronic cholecystitis. Other testsroutine blood investigations, coagulation profile, Hepatitis B serology test, HIV and syphilis tests, renal and liver function tests and so onwere then performed in the emergency department.

Electrocardiogram findings were normal with his sinus rhythm noted.

Zheng Ren instructed a nurse to insert a nasogastric tube for gastric decompression before inviting the patients son to his office for preoperative counseling.

The son was dejected as he was the one who insisted on a hospital discharge due to the noisy environment disturbing his fathers rest.

He did not expect his father to have cholecystitis just as Zheng Ren predicted.

Zheng Ren had had a good relationship with the family members of the patients who had been receiving treatment in the emergency department observation unit, so he chose to comfort the patients son first after they had sat down in his office.

After that, he began explaining the patients condition based on his ultrasonography.

This was not a simple case of acute cholecystitis, and its cause had been explained previously. Acute food poisoning would cause transient derangement in liver function, which would result in exudation. The exudate would accumulate in the gallbladder fossa and infiltrate the gallbladder, finally causing acute cholecystitis.

The possibility of young men getting cholecystitis was very minimal. After all, they were in better physical shape and had stronger immune systems, so their bodies would be able to deal with inflammatory responses easily.

Older men were different and could not handle inflammation well, hence the cholecystitis. If conservative treatment with antibiotics was used, it would not have much effect.

After listening to the explanation, the family member stated that he would follow Zheng Rens arrangements.

It was a sign of trust in the doctor after a period of acquaintance.

If the major rescue operation for nitrite poisoning had been unsuccessful, he would not have so unhesitatingly agreed to Zheng Rens suggestions.

Lets do cholecystectomy then. Zheng Ren decided for a surgery in the end.

The old man was prepared for surgery straight away as he was in intense pain and had fasted long enough due to having a decreased appetite after experiencing discomfort in the morning.

The test results came back half an hour later and the patient had no contraindications for surgery. After counseling the patient and acquiring signatures on the preoperative informed consent documents, Zheng Ren brought the patient to the operating theater on the third floor of the emergency building.

According to the initial design plan for the emergency building, the first floor had the emergency department, observation units, B-scan ultrasonography room, CT scanner and various auxiliary departments. The emergency wards were located on the second floor with fifty-two sickbeds, and the third floor with a few thousand square meters was designated for operating theaters. This full-flow design was among the top in China.

Various surgery departments had set their sights on the high-class operating theater, which was the main reason Old Chief Physician Pan had been so eager to develop emergency surgery. If the emergency department had no use for it, someone else would take over instead of letting it go to waste.

Deep inside the operating theater on the third floor lay an interventional radiology suite, which was dedicated specifically for interventional radiology.

The suite had been constructed based on a new designa hybrid operating room.

A hybrid operating room was an advanced procedural space that combined the traditional operating theater with interventional radiology.

This was advanced technology as ordinary Class Three Grade A Hospitals did not have hybrid operating rooms.

However, the hybrid operating room in Sea City General Hospital had been idle for a long time. The hospital management would be held responsible for wasting resources recklessly if no one tried to seize the opportunity to assume control of it.

The operating theater was fully equipped with disinfection facilities and the still air was maintained at a constant temperature to control airborne infection. Anyone who took a deep breath in this room would get the feeling that the air could purify ones soul.

Zheng Ren went to the male locker room to change into surgical attire while the other doctors assisted with the patient transfer.

He was convinced that, instead of conspiring against him, the System had actually predicted that he would perform cholecystectomy in the future. Well, what was he waiting for? It was time to spend all his skill and experience points in the System for intensive training in laparoscopic cholecystectomy!

In the male locker rooms smoking area, Zheng Ren lit up a cheap Ziyun [1]and took a deep drag comfortably before diving into the System.

As he entered, he decided not to spend his skill points, which were but a drop in the ocean. There was no way he could achieve the Master rank and receive a skill upgrade anyway.

He opened the Shop interface, clicked on cholecystectomy and exchanged his entire stock of 75000 experience points from the last mission reward for 20.83 hours of intensive training. Then, as the operating theater formed around him, training had officially begun.

It saved time performing surgery in the System as the mannequins were anesthetized in advance.

In reality, a cholecystectomy required at least two hours from start to finish, but in the Systems operating theater, Zheng Ren could simply focus on mastering his skills without having to wait for the anesthesia to take effect or consider the patients condition and postoperative recovery.

The first laparoscopic cholecystectomy took Zheng Ren nearly an hour to complete. After all, he had not been qualified to perform a cholecystectomy even when he was still in the first general surgery department even though it was just a tier-one surgery.

Subsequent surgeries became much smoother after he had familiarized himself with it.

The time required for each surgery gradually decreased just like during the intensive training for appendectomies. In a sense, one just needed to practice general surgery repeatedly to master it.

In the end, Zheng Ren required only ten minutes to finish a laparoscopic cholecystectomy.

No matter how Zheng Ren made the best use of his intensive training time, in less than twenty-one hours, he merely did eighty surgeries in total.

Even so, he felt particularly good as those practice runs were more than enough to handle this situation.

After his intensive training ended, Zheng Ren turned around and checked his general surgery skill tree, which had increased from 1692 to 1930 skill points. He was unsure if this sharp increment had anything to do with the difficulty of the operation.

Long, gray wisps of smoke still hung in the air when Zheng Ren returned to reality. He then stubbed out the cigarette that he had just taken a puff of, put it back into its pack, changed into surgical attire and went into the operating theater.

Xie Yiren, who had already prepared herself and was standing in front of the instrument table, gave Zheng Ren a warm smile as he entered.

The first cholecystectomy was about to begin.
