Discover the surgical principles behind three-port laparoscopic gallbladder removal using a subserosal dissection technique, presented by Prof. Dr. R. K. Mishra. This educational video from World Laparoscopy Hospital explores how careful tissue-plane identification, coordinated laparoscopic movements, effective exposure, and meticulous hemostasis contribute to a controlled operative procedure.

Laparoscopic cholecystectomy is an established minimally invasive operation for appropriate patients with symptomatic gallstones and selected gallbladder disorders. Using three ports rather than the conventional four-port arrangement changes the instrument configuration and may require adjustments in traction, camera positioning, and the surgeon's working angles. The number of ports alone does not determine the safety or success of the operation; patient selection, surgical expertise, anatomical clarity, and sound decision-making remain fundamental.

The Concept of Bloodless Gallbladder Dissection

During gallbladder removal, small vessels and tissue attachments may be encountered between the gallbladder and liver bed. Careful dissection aims to control these attachments while preserving visibility and minimizing avoidable bleeding. A relatively clear operative field can support anatomical orientation and help the surgeon recognize changes in the tissue plane.

Subserosal dissection focuses on separating the gallbladder along an appropriate plane close to its wall. The exact plane and method may vary with inflammation, fibrosis, gallbladder wall thickness, and individual anatomy. Excessively deep dissection, forceful traction, or inappropriate energy application can cause bleeding or injury. For this reason, controlled movements and repeated assessment of the operative field are essential.

A Detailed Overview of the Operative Workflow

Step 1: Patient assessment and surgical planning

The surgeon reviews the patient's symptoms, examination findings, imaging, and relevant medical history. The presence of acute inflammation, adhesions, suspected common bile duct stones, or unusual anatomy may influence the operative plan. A three-port approach should be used only when it provides appropriate access and does not compromise safe exposure.

Step 2: Establishing laparoscopic access

Following anesthesia and surgical preparation, abdominal access is established and pneumoperitoneum is created using an appropriate method. Three ports are positioned to support visualization and the necessary working movements. The surgeon checks the camera view, instrument reach, and ability to retract the gallbladder effectively.

Step 3: Achieving optimal exposure

The gallbladder is manipulated to expose its neck and surrounding structures. Effective traction and countertraction help distinguish tissue planes and improve the view of the hepatocystic triangle. The surgeon must remain alert to distorted anatomy, adhesions, and inflammatory changes that may make normal landmarks difficult to recognize.

Step 4: Subserosal separation from the liver bed

Dissection proceeds with controlled movements along the selected plane. The surgeon aims to separate the gallbladder from its liver attachment while minimizing unnecessary bleeding and tissue trauma. Appropriate instruments and energy settings are selected according to the tissue characteristics and operative situation. Any bleeding should be managed promptly, with visibility restored before proceeding.

Step 5: Securing anatomical safety

Before the cystic duct or cystic artery is divided, their identity must be established using safe anatomical principles. The critical view of safety is a central reference point: the hepatocystic triangle is cleared of fat and fibrous tissue, the lower part of the gallbladder is separated from the liver bed, and only two structures should be seen entering the gallbladder.

The surgeon should assess the view carefully before dividing either structure. When the anatomy is uncertain, persisting with the planned dissection may increase the risk of injury. Depending on the circumstances, options can include intraoperative imaging, seeking assistance, changing the dissection strategy, performing a subtotal cholecystectomy, or converting to open surgery. The safest option depends on the specific operative findings.

Step 6: Completing gallbladder separation

After the relevant ductal and vascular structures have been safely identified and divided, dissection of the remaining gallbladder attachments is completed as appropriate. The surgeon maintains visualization of the liver bed and checks for bleeding, bile leakage, or signs of inadvertent injury.

Step 7: Inspection and completion

The gallbladder is retrieved, the operative field is inspected, and any concerns are addressed. Port removal and wound closure follow the surgeon's operative protocol. Postoperative observation and discharge planning depend on the patient's recovery, operative findings, and institutional practice.

Technical Challenges and Safety Considerations

A three-port approach can require careful coordination because the instruments enter through fewer access points. Instrument collision, limited triangulation, difficult retraction, and poor visualization may make dissection more challenging in some cases. Additional access should be used whenever needed to maintain safe exposure; minimizing port number should never take priority over patient safety.

Similarly, the term “bloodless cholecystectomy” should be understood as an aspiration to minimize bleeding, not as a promise that bleeding will not occur. Even with meticulous technique, unexpected vascular bleeding, gallbladder perforation, bile leakage, and bile duct injury remain possible. Thermal injury may also occur if energy devices are used too close to vulnerable structures.

Safe-cholecystectomy recommendations emphasize accurate anatomical identification and a deliberate pause to verify the critical view before dividing structures. If that view cannot be achieved, the surgeon should consider an appropriate alternative rather than relying on assumptions or proceeding with uncertain anatomy.

Educational Value for Laparoscopic Surgeons

For surgeons and trainees, this procedure offers important learning opportunities in:

• Three-port instrument arrangement and laparoscopic ergonomics.

• Traction, countertraction, and exposure of the gallbladder.

• Recognition of tissue planes during subserosal dissection.

• Principles of hemostasis and careful energy application.

• Identification of biliary anatomy and the critical view of safety.

• Recognition of difficult dissection and selection of alternative strategies.

• Final inspection for bleeding, bile leakage, and other operative concerns.

These skills are relevant to the broader practice of minimally invasive surgery. However, a video demonstration is a supplementary learning tool, not a substitute for formal surgical training, supervised practice, or an individual surgeon's clinical judgment.

World Laparoscopy Hospital: Surgical Learning and Professional Development

World Laparoscopy Hospital provides a setting for medical professionals to study laparoscopic and robotic surgery through structured educational activities. Operative demonstrations can help learners connect anatomical knowledge with surgical steps and develop a more systematic understanding of minimally invasive procedures.

Under the guidance of experienced faculty such as Prof. Dr. R. K. Mishra, trainees can study the reasoning behind operative decisions, the importance of maintaining visualization, and the need to adapt a technique when patient-specific conditions require it. The goal of surgical education is not simply to reproduce a sequence of movements, but to understand why each step is performed and when an alternative approach may be safer.

Watch this surgical demonstration to review the principles of three-port laparoscopic subserosal cholecystectomy, with particular attention to dissection technique, hemostasis, anatomical identification, and safe operative decision-making.
