This video describes a standard approach for laparoscopic cholecystectomies with ideal anatomy. In laparoscopic cholecystectomy, the safest and best approach to identify the structures of the Triangle of Calot is to achieve the Critical View of Safety (CVS). The Triangle of Calot is also known as the cystohepatic triangle. It is bounded by the inferior surface of the liver, the cystic duct, and the common hepatic duct. To achieve CVS, the Triangle of Calot must be clearly dissected, the lowest part of the gallbladder must be separated from the cystic plate, and only two structures should be seeing entering the gallbladder - the cystic artery and the cystic plate.

Laparoscopic cholecystectomy is the gold standard treatment for symptomatic gallstone disease and other gallbladder disorders. Introduced in the late 1980s, this minimally invasive procedure revolutionized gallbladder surgery, offering patients reduced postoperative pain, shorter hospital stays, faster recovery, and superior cosmetic results compared to open surgery.

Indications

Standard laparoscopic cholecystectomy is primarily indicated for:

• Symptomatic cholelithiasis (gallstones causing pain or biliary colic)

• Acute or chronic cholecystitis

• Gallbladder polyps larger than 1 cm

• Biliary dyskinesia with abnormal gallbladder ejection fraction

• Gallstone pancreatitis (after stabilization)

Contraindications
While generally safe, certain conditions may require caution or conversion to open surgery:

• Severe cardiopulmonary compromise preventing pneumoperitoneum

• Extensive abdominal adhesions from previous surgeries

• Suspected gallbladder carcinoma

• Severe coagulopathy

Preoperative Preparation
Patients undergo a detailed history, physical examination, and imaging studies, most commonly abdominal ultrasound. Routine blood tests, liver function tests, and coagulation profile are performed. Preoperative fasting and prophylactic antibiotics are standard to reduce the risk of infection.

Surgical Technique

1. Patient Positioning:
   The patient is placed in a supine position with slight reverse Trendelenburg and left tilt to allow the liver and gallbladder to move away from the surgical field.

2. Port Placement:
   Standard laparoscopic cholecystectomy typically uses four ports:

   • Umbilical port for the laparoscope

   • Epigastric port for dissection

   • Two lateral ports for retraction and instrumentation

3. Creation of Pneumoperitoneum:
   Carbon dioxide is insufflated to achieve a working space, usually maintaining an intra-abdominal pressure of 12–15 mmHg.

4. Dissection:

   • The Calot’s triangle is carefully dissected to identify the cystic duct and cystic artery.

   • The principle of Critical View of Safety (CVS) is strictly followed to prevent bile duct injury.

5. Clipping and Division:

   • The cystic duct and artery are clipped and divided.

   • The gallbladder is separated from the liver bed using electrocautery.

6. Extraction:
   The gallbladder is retrieved through the umbilical port, often using an endoscopic bag to prevent spillage of bile or stones.

7. Closure:
   Ports are removed, pneumoperitoneum is released, and the skin incisions are closed with absorbable sutures or skin adhesive.

Postoperative Care
Patients typically resume oral intake within a few hours post-surgery. Pain management is achieved using oral analgesics, and ambulation is encouraged to prevent complications such as deep vein thrombosis. Most patients are discharged within 24 hours.

Complications
Though minimally invasive, laparoscopic cholecystectomy carries potential risks:

• Bile duct injury

• Bleeding

• Infection at port sites

• Bile leakage

• Retained stones in the common bile duct

Advantages

• Reduced postoperative pain

• Shorter hospital stay

• Faster return to normal activities

• Smaller incisions with better cosmetic results

• Lower risk of wound infection

Conclusion
Standard laparoscopic cholecystectomy remains the preferred treatment for gallbladder diseases due to its safety, efficacy, and minimally invasive nature. Adherence to surgical principles, especially the Critical View of Safety, ensures optimal outcomes and reduces complications. With advances in surgical techniques and instrumentation, patient recovery continues to improve, solidifying laparoscopic cholecystectomy as a cornerstone of modern surgery.
