Laparoscopic splenectomy is a technically demanding operation in which surgical exposure, anatomical orientation, vascular control, and atraumatic tissue handling are central to successful operative performance. This educational video provides a detailed look at the principles behind laparoscopic removal of the spleen, with emphasis on operative strategy, important anatomical landmarks, and practical techniques that can help surgeons approach the procedure in a structured manner.

Unlike many straightforward laparoscopic procedures, splenectomy involves an organ that is highly vascular and closely associated with several important structures. The splenic hilum contains major vessels, while the pancreatic tail lies nearby. The stomach and short gastric vessels are also encountered during mobilization. These relationships explain why controlled exposure and precise dissection are essential.

Understanding the Operative Anatomy

Before beginning the dissection, the surgeon should develop a clear mental map of the left upper quadrant. The spleen is related to the stomach anteriorly and medially, the diaphragm superiorly, the left kidney posteriorly, and the colon inferiorly. The pancreatic tail approaches the splenic hilum.

Understanding these relationships allows the surgeon to anticipate where critical structures will be encountered during mobilization.

The splenic vessels may demonstrate anatomical variation, so the surgeon should avoid assuming that every patient has identical hilar anatomy. Careful visualization and progressive dissection are particularly important around the splenic hilum.

Creating the Right Surgical View

A major principle in laparoscopic splenectomy is obtaining an adequate operative view before dividing important structures. Patient positioning can assist exposure by allowing gravity to move abdominal organs away from the spleen.

The lateral approach has been described extensively in laparoscopic splenectomy, with clinical experience demonstrating that it can provide effective access to the spleen and facilitate its mobilization.

Port placement should provide appropriate access to the upper pole, lower pole, posterior attachments, and hilar region. The exact configuration should be adapted to the patient's anatomy and spleen size rather than treated as a rigid template.

Mobilization: The Key to the Operation

Mobilization is often the defining technical phase of laparoscopic splenectomy. The surgeon progressively releases the spleen from its surrounding attachments while maintaining appropriate traction.

The spleen should be handled gently because capsular tears can rapidly produce bleeding and obscure the operative field. Rather than pulling forcefully on the organ, the surgeon should use controlled movements and develop the appropriate tissue planes.

The assistant also has an important role. Appropriate retraction can expose the posterior and medial surfaces and make subsequent dissection easier.

Short Gastric Vessels

The short gastric vessels are an important part of splenic mobilization. They connect the splenic circulation with the gastric circulation and are encountered between the stomach and spleen.

Careful exposure of these vessels before division helps reduce the risk of inadvertent gastric injury. The surgeon should maintain visual control of both the vessel and surrounding tissues before using an energy or vascular-sealing device.

This is an excellent example of a broader laparoscopic principle: never allow the instrument to become the primary guide—anatomy should guide the instrument.

Approaching the Splenic Hilum

Once the spleen has been adequately mobilized, attention turns toward the hilar structures. This is generally one of the most technically sensitive stages of the procedure.

The splenic artery and vein must be clearly identified before vascular control. Depending on the anatomy and surgical strategy, the surgeon may approach the hilum in different ways.

The objective is secure vascular control with minimal manipulation of the spleen and avoidance of adjacent structures, particularly the pancreatic tail.

Splenic hilar dissection is recognized as technically challenging because of the narrow working space, vascular variation, and potential for significant bleeding.

Managing Bleeding

Bleeding is one of the most important concerns during splenectomy. The surgeon should therefore maintain a deliberate strategy for vascular control from the beginning of the procedure.

Small bleeding points should be addressed promptly rather than allowed to accumulate and obscure the anatomy. If significant bleeding occurs, the first priority is to obtain visualization and controlled compression rather than immediately applying an energy device without identifying the source.

When laparoscopic control is not achievable safely, conversion to an open approach may be appropriate. Historical literature on laparoscopic splenectomy describes conversion in cases involving bleeding or significant splenomegaly, reinforcing the importance of patient selection and readiness to change strategy.

Specimen Retrieval

Once the spleen has been completely detached, specimen retrieval becomes the next major consideration.

For smaller spleens, extraction through an appropriately selected incision may be possible. Larger spleens may require extension of a port site, a hand-assist strategy, or another planned extraction method. Published clinical experience has described both intact and morcellated extraction approaches.

The underlying pathology must always influence this decision. When malignancy is suspected, the specimen should be handled according to appropriate oncologic principles, and unnecessary fragmentation should be avoided.

Searching for Accessory Spleens

A systematic search for accessory splenic tissue is another important consideration. Accessory spleens can occur in different locations within the abdominal cavity, including near the splenic hilum and surrounding ligaments.

Their identification may be particularly relevant in patients undergoing splenectomy for hematologic disorders. Clinical series have demonstrated that accessory spleens can be identified and removed laparoscopically when present.

Final Check Before Closure

After removal of the spleen, the surgeon should perform a methodical inspection of the operative field.

Particular attention should be directed toward:

• The splenic bed
• Splenic hilar vessels
• Pancreatic tail
• Gastric attachments
• Diaphragmatic surface
• Areas where short gastric vessels were divided
• Potential accessory splenic tissue

The operative field should be free of significant bleeding before completion of the procedure.

Technical Pearls for Surgeons

A useful technical pearl is to prioritize exposure over speed. A few additional minutes spent achieving proper visualization can make subsequent dissection substantially more controlled.

Another principle is to maintain continuous anatomical orientation. The surgeon should know the location of the stomach, pancreatic tail, splenic vessels, and diaphragm throughout the procedure.

Controlled traction is equally important. Excessive traction can create capsular tears, while insufficient traction can make tissue planes difficult to identify.

The assistant should actively participate in exposure rather than simply holding an instrument. Proper countertraction can transform a difficult dissection into a much clearer operative field.

Finally, the surgeon should maintain a low threshold for changing the operative strategy when visualization is inadequate or bleeding cannot be controlled safely.

Why Laparoscopic Splenectomy Matters

Laparoscopic splenectomy became an important development in minimally invasive surgery because selected patients can benefit from the minimally invasive approach. Published clinical experience has associated laparoscopic splenectomy with smaller incisions and, in appropriate patients, reduced postoperative pain and shorter hospitalization compared with conventional open surgery.

Modern minimally invasive surgery continues to refine these techniques, including approaches involving smaller access incisions and even single-incision strategies in selected cases. Such approaches further emphasize the importance of understanding surgical anatomy and instrument geometry.

However, minimally invasive access should never override the basic principles of safe surgery. The appropriate approach depends on patient factors, pathology, spleen size, surgeon experience, and intraoperative findings.

This educational step-by-step presentation of laparoscopic splenectomy therefore provides a valuable framework for understanding the operation from initial positioning and access through mobilization, short gastric vessel management, hilar control, specimen retrieval, and final inspection.

The most important takeaway is simple: excellent exposure, precise anatomy, gentle handling, secure vascular control, and readiness to adapt are the foundations of safe laparoscopic splenectomy.
