Robotic-Assisted Hepatectomy

What Is Hepatectomy?

A liver resection, also known as hepatectomy, is a surgical intervention to extract a portion of the liver. As long as the remaining portion of the liver is in good health, it is possible to have a surgical procedure to remove up to two-thirds of the liver. If one is diagnosed with liver disease, a partial hepatectomy may be performed to remove a lesser amount of the liver. Regeneration of the liver is possible. If the remaining liver is healthy, it will regenerate and return to its original size.

What Are the Advantages of Robotic-Assisted Hepatectomy?

1. Enhanced Postoperative Recovery: The majority of patients are discharged from the hospital within three to four days after undergoing major robotic liver resection and within two days after undergoing minor liver resections. Minimally invasive robotic liver surgery procedures greatly decrease the occurrence of cardiac and pulmonary problems. Quicker recovery from liver resections results in an earlier application of systemic chemotherapy in patients requiring subsequent systemic chemotherapy.

2. Minimal Blood Loss: Most liver resections conducted with robotic technology result in less than 100 cc of blood loss. Major liver resections seldom require a blood transfusion.

3. Reduced Pain: The majority of patients report minimal pain and require only a small amount of pain-relieving medication, even following significant liver resections.

4. Negligible Risk of Wound Infection: Compared to open liver resection, the likelihood of experiencing a surgical wound infection is greatly reduced, less than one percent.

5. Reduced Risk of Hernia Formation - Small incisions have a considerably decreased likelihood of causing incisional hernias. To minimize the risk of hernia formation post-surgery, it is advisable to refrain from making a substantial incision.

6. Enhanced Aesthetic Result - Small incisions heal with minimal, frequently imperceptible scars

What Are the Complications of Other Surgical Methods in Hepatectomy?

The postoperative complications include the following:

• Morbidity or death.

• Bile leak.

• Transient liver failure.

• Ascites: Ascites refers to the abnormal fluid accumulation in the abdominal cavity.

Surgery-related complications include the following such as:

• Pleural Effusion: Pleural effusion is the accumulation of fluid in the pleural cavity.

• Prolonged Ileus: Chronic intestinal obstruction.

• Thoracic Empyema: A thoracic empyema is an infection that is marked by open pus in the pleural area.

• Urinary Bladder Injury

• Wound Infection

General complications include such as:

• Transient Ischemic Attack: A brief episode that resembles a stroke but resolves in a matter of minutes to hours; however, it needs to be treated medically right once it is differentiated from a stroke.

• Deep Vein Thrombosis: Deep vein thrombosis (DVT) is the formation of a blood clot (thrombus) in one or more of the deep veins in the body, typically in the legs. Deep vein thrombosis may result in discomfort or enlargement of the leg. Occasionally, there may be an absence of discernible symptoms.

Bile leakage was the most prevalent consequence. In addition to bile leakage, the sole consequence arising directly from the surgical approach was damage to the urinary bladder.

What Are the Difference Between Traditional and Robotic Liver Resection Surgery?

Surgery is frequently a crucial component of the treatment of liver cancer. The liver possesses a distinctive characteristic whereby it can progressively regenerate itself after removing a damaged portion. Hence, the objective of liver resection surgery is to excise a tumor while retaining an ample amount of the organ to uphold liver functionality.

Due to its location in the upper right quadrant of the abdomen, the liver is frequently challenging to access during surgical procedures. Therefore, open liver resection surgery typically necessitates a substantial abdominal incision that begins below the ribs and extends to the center.

Robotic liver resection surgery offers a minimally invasive way for surgeons to access and remove some liver tumors, eliminating the requirement for a big incision and the associated risks of complications.

The choice of surgical procedure for liver cancer treatment is contingent upon the tumor's location, stage, extent, and other individualized patient characteristics. Several frequently executed procedures include:

1. Wedge resection is a surgical procedure that involves the removal of a tumor along with a portion of the surrounding tissue.

2. Single segmentectomy refers to the surgical procedure of removing one of the liver's eight segments.

3. Hepatic lobectomy refers to the surgical procedure of removing one of the two lobes of the liver.

Adopting sophisticated technology, such as the robotic surgical system, can improve minimally invasive liver resection surgery. Consequently, numerous treatments that typically necessitate a significant surgical cut can be carried out through a handful of minor incisions.

The main benefits of robotic liver resection surgery, as compared to traditional open surgery for liver cancer therapy, include improved intraoperative visualization and dexterity, as well as reduced scarring and a quicker recovery. Enhancing surgical precision can immediately result in improved results and enhanced quality of life for the patients. Furthermore, the level of a surgeon's accuracy improves with each procedure conducted.

What Is the Procedure for Doing Robotic Liver Operations for Benign and Malignant Liver Tumors?

The liver comprises two lobes, the right and left lobes, which are divided into eight segments. The main goal of curative liver resection is to surgically remove the tumor with clear margins while also preserving as much functioning liver tissue as feasible. For a successful conclusion, it is crucial to accurately identify and treat the blood veins entering and exiting the liver and the main bile ducts. Preserving the integrity of blood arteries and bile ducts is necessary for optimal post-surgical liver function. Peripherally situated liver tumors can be surgically removed using a local resection technique. Tumors that are bigger or positioned at a greater depth in the liver typically necessitate a more comprehensive or formal surgical removal.

Robotic surgery can be used for both minor and big liver resections. Minimally invasive liver resection is the preferable method over the standard open operation when it is technically feasible, as assessed by the surgical team.

Conclusion

Both major and minor robotic hepatectomy are safe and effective procedures, yielding comparable patient morbidity, mortality, and oncological resection results. However, significant obstacles remain to the broader use of this technology, mostly related to cost, training, and the platform itself. Collaborations among industry, academia, and surgeons are expected to solve these challenges, enabling the widespread adoption of robotic liver surgery and providing benefits to patients.
