The most commonly used procedure in the treatment of solitary large liver cysts is the excision of the liver cyst. Surgery can be performed laparoscopically or open surgery, but the most common option currently is laparoscopic. In which, endoscopic liver cystectomy is a complicated technique and requires the operator to be proficient.

1. What is a liver cyst?

Simple hepatic cysts are common and benign lesions. Very few patients with liver cysts present with symptoms and require medical intervention. These epithelial cells secrete follicular fluid, whose composition is similar to that of plasma. Like white blood cells, cyst fluid does not contain bilirubin or amylase. Rarely, there is communication between the cyst and the bile and there is a yellow color of bile in the cyst fluid.

2. Laparoscopic hepatectomy

2.1. Indications and contraindications Laparoscopic surgery to remove liver cysts from the body is called laparoscopic liver cystectomy.
Indications: Only laparoscopic liver cystectomy is performed when the following factors are satisfied:
Presence of solitary liver cyst or large liver cyst at risk of rupture Thin cyst wall Cyst is located in the middle segment, Anterior and lateral Contraindications: Do not perform laparoscopic liver cystectomy if
Germs appear in the cyst (superinfected cyst) - there is an anastomosis between the cyst and the biliary tree. Suspected malignant cyst, liver fluke cyst Location of liver cyst in posterior segment 2.2. Procedure for performing laparoscopic liver cystectomy Things to keep in mind when performing this technique:
The patient needs to be enema to clean the colon. On the morning of surgery, the patient needs to fast and disinfect the abdomen. Use prophylactic antibiotics at the time of skin incision. Patients need to breathe oxygen, closely monitor pulse, blood pressure, temperature, urine, drainage within the first 24 hours. On the first day after surgery, the patient should have a complete blood count test, basic coagulation, biochemical liver and kidney function, and electrolytes. The patient can eat again, food from liquid to solid gradually, the amount gradually increases on the 3rd day after surgery. 2.3. Benefits of laparoscopic liver cystectomy laparoscopic liver cystectomy is the preferred surgical method today because it has many advantages, such as:
Less invasive to the patient's body Patient's health is guaranteed and safe About 8 hours after surgery, the patient can recover, eat and travel. Short hospital stay Saves on treatment costs compared to other methods. However, like other surgical techniques, laparoscopic liver cystectomy may also have undesirable effects.

3. Endotracheal anesthesia for laparoscopic liver cystectomy

Endotracheal anesthesia is a technique of general anesthesia through endotracheal tubes for the purpose of controlling breathing during surgery and resuscitation after surgery for patients. This method requires medical facilities to have all the necessary modern equipment, and the operator must be trained and proficient in techniques.
3.1. Steps to carry out endotracheal anesthesia for laparoscopic liver cystectomy Check records Check the patient Technical implementation: The general steps are: Patient position: supine, 100% oxygen at a rate of 3-6 l/min at least 5 minutes before induction of anesthesia. Install the tracker. Set up transmission. If necessary, pre-anesthesia can be performed. Induction of anesthesia: sleeping pills Pain relievers Muscle relaxants (if necessary) The condition for intubation is that the patient must sleep deeply and have enough muscle relaxation. Carrying out oral intubation: insert the endotracheal tube through the mouth, put the cannula in the mouth to prevent the patient from biting the tube (if necessary). Maintain anesthesia with intravenous or volatile anesthetics, analgesics, and muscle relaxants (if needed). Control the patient's breathing with a machine. Criteria for extubation: The patient is awake, following the doctor's orders. Patient can raise head for more than 5 seconds, TOF >0.9. The patient is breathing on his own, the respiratory rate is within normal limits. Pulse and blood pressure are stable. Temperature > 35 degrees C. The patient had no complications of anesthesia and surgery. 3.2. Complications and management in endotracheal anaesthesia laparoscopic liver cystectomy. Reflux of gastric juice into the airway Gastrointestinal fluid was found in the oral cavity and airways. At that time, it is necessary to immediately aspirate the fluid, place the patient in a low position, and tilt the head to one side. Place the endotracheal tube quickly and clear the airways immediately. Then it is necessary to monitor for lung infections. Hemodynamic disorders Patients with hypotension or hypertension, cardiac arrhythmias (tachycardia, bradycardia or arrhythmia). Treatment depends on the specific symptoms and cause.

Incident due to intubation Unable to intubate: manage with difficult intubation procedure or switch to another anesthetic method. Wrong placement of endotracheal tube into the stomach: Auscultation of the lungs without alveolar murmur, EtCO2 cannot be measured. Reinsert the endotracheal tube. Vocal - tracheobronchial spasm: Difficult or impossible to ventilate, auscultation with rales or no hearing at all. It is necessary to provide adequate oxygen to the patient, use more hypnotics and muscle relaxants, ensure ventilation, and use bronchodilators and corticosteroids. If breathing cannot be controlled, a difficult endotracheal intubation procedure should be used. Trauma during endotracheal intubation: patients have bleeding, broken teeth or damaged vocal cords, foreign objects fall into the airways,... Depending on the injury, appropriate treatment is available. Respiratory complications Possible folding or retraction of the endotracheal tube deep into one lung, collapse or opening of the respiratory system, lack of oxygen. Management: immediately ensure ventilation and provide 100% oxygen, find and resolve the cause. Complications after extubation Patients may experience respiratory failure after extubation. The patient may have a sore throat and hoarseness. Patient has laryngospasm - gas - bronchi. The patient may have an upper respiratory tract infection. The patient may have laryngotracheal stenosis. Depending on the symptoms and cause, the doctor will have an appropriate treatment.
