Laparoscopic liver surgery has been shown to have several advantages over open liver resection, including reduced blood loss, decreased wound pain, and shorter hospital stay while maintaining comparable oncological outcomes1,2,3,4. Although LRPS was previously considered a relative contraindication due to its deep-seated anatomic location and challenges in bleeding control, recent advancements have proven its safety and feasibility2,5,6,7. Various strategies and surgical devices have been developed to overcome these challenges. However, no consensus exists on the best surgical technique and devices for LRPS.
In this article, we aim to provide a detailed description of the steps involved in LRPS at our centre, with a specific focus on the intrahepatic Glissonian approach for inflow control, a novel technique called the &#39;ultrasonic scalpel mimic Cavitron ultrasonic surgical aspirator (CUSA)&#39; for parenchymal transection, early identification of the right hepatic vein, and meticulous bleeding control using bipolar diathermy. Machado et al. and Topal et al. reported the feasibility and safety of the laparoscopic intrahepatic Glissonian approach8,9,10. Laparoscopic techniques offer improved visualization and precision in dissecting the Glissonian pedicle. The approach maintains the blood flow to the remnant liver, reducing the risk of ischaemic injury. Additionally, this approach allows for the exact demarcation of liver segments that are being resected, making the surgery more precise and reducing the risk of bleeding. Professor Kwon introduced the &#39;ultrasonic scalpel mimic CUSA&#39; technique in 201911, which has been shown to reduce intraoperative blood loss and operative time11,12.
A representative case is discussed in this study to detail the steps performed in the protocol. The patient is a 54-year-old man who is a chronic carrier of hepatitis B. During screening ultrasonography, a liver mass was identified in segment 6. A pre-operative triphasic computed tomography (CT) scan was performed, which revealed a 5.7 cm hypervascular tumor with arterial enhancement and portovenous washout in segment 7 (Figure 1).&#160;The alpha-fetoprotein (AFP) level was 2 ng/ml. The Child-Pugh score was 5 (Grade A). The indocyanine green retention at 15 min was 7.5%. The residual liver volume (RLV) was 45%. Based on the patient&#39;s hepatitis status and the radiological features of the tumor, the mass was treated as hepatocellular carcinoma. The patient was offered a laparoscopic right posterior sectionectomy, including the right hepatic vein.

techniques of laparoscopic right posterior sectionectomy: glissonian approach and a parenchymal transection technique

Laparoscopic liver resections (LLR) have been widely accepted as a treatment option for liver tumors. They offer several advantages over open liver resections, including less blood loss, reduced wound pain, and shorter hospital stays with a comparable oncological outcome. However, laparoscopic resection of lesions in the right posterior section of the liver is challenging due to difficulties in bleeding control and visualizing the surgical field. In the past, laparoscopic right posterior sectionectomy (LRPS) was still in the exploration phase, with undefined risks in the Second International Consensus Conference on LLR in 2014. However, recent technological advancements and increased surgical experience have shown that LRPS can be safe and feasible. It has been found to reduce hospital stay and blood loss compared to open surgery. This manuscript aims to provide a detailed description of the steps involved in LRPS. The key factors contributing to our success in this challenging procedure include proper liver retraction and exposure, the use of an intrahepatic Glissonian approach for inflow control, a technique called the 'ultrasonic scalpel mimic Cavitron ultrasonic surgical aspirator (CUSA)' for parenchymal transection, early identification of the right hepatic vein, and meticulous bleeding control using bipolar diathermy.

In the representative case, the total operative time was 738 min, with an estimated blood loss of 400 mL. The patient was nursed in the intensive care unit for 2 days. The recovery was uneventful, and the patient was discharged on postoperative day 5. Histopathological examination of the specimen revealed moderately differentiated cholangiocarcinoma measured 8.0 cm x 5.5 cm x 4.5 cm. There was no perineural or lymphovascular permeation. The resection margin was 14 mm. The American Joint Committee on Cancer (AJCC) staging...

Techniques of Laparoscopic Right Posterior Sectionectomy: Glissonian Approach and a Parenchymal Transection Technique

Here, we present a protocol to perform laparoscopic right posterior sectionectomy, focusing on two key aspects: the intrahepatic Glissonian approach for inflow control and a parenchymal transection technique using an ultrasonic surgical aspirator.

After inserting the laparoscope ports in the patient, complete the division of the triangular ligament until the bare area of the liver is exposed. Expose the groove that lies between the right hepatic veins and the common trunk of the middle and left hepatic veins. Then, incise the inferior peritoneal attachment and gently lower the adrenal gland to the retroperitoneum.Divide the short hepatic veins and the ligament connecting to the vena cava until the inferior border of the right hepatic vein becomes visible. Carefully dissect along the superior border of the right posterior Glissonean pedicle along the Rouviere's sulcus, while ensuring the integrity of the Laennec capsule. Then transect the caudate process to reveal the inferior margin of the right posterior Glissonean pedicle.Dissect along the inferior border of the right posterior Glissonean pedicle along the Rouviere's sulcus. Using a bulldog clamp, control the right posterior pedicle. With the help of an ultrasonic scalpel, carefully open the liver capsule.Make the incision at the dome of the liver, precisely along the left margin of the right hepatic vein, ensuring a secure and accurate transection plane. Then use diathermy to mark the remainder of the transection line along the ischemic line. Using Huang's loop and a shortened Foley catheter, prepare an intracorporeal tourniquet for the laparoscopic Pringle maneuver.Carefully open the liver capsule along the predetermined transection line. Heat both arms of the ultrasonic scalpel in the open position. Utilize the active blade of the ultrasonic scalpel for tissue dissection.Activate the ultrasonic scalpel at its maximum power setting, and move the active blade in a horizontal swinging motion parallel to the vasculobiliary structures. Then dissect the liver parenchyma while exposing individual intrahepatic vessels and ensuring their preservation. Employ a suction device with the left hand to maintain a dry surgical field continually.And then use either plastic clips or metal clips to divide large vessels or pedicle structures. Use an ultrasonic scalpel to divide small vessels. To address bleeding, use bipolar diathermy while simultaneously using suction to maintain a clear surgical field.Wrap vascular tape around the right posterior pedicle before cutting with a vascular stapler. Use intracorporeal sutures for significant bleeding, such as bleeding from the right hepatic vein. Transect the right hepatic vein using a vascular stapler.Finally, place the specimen into a plastic bag and retrieve the specimen through the Pfannenstiel incision. In the representative case, the total operative time was 738 minutes, with an estimated blood loss of 400 milliliters. The patient was discharged on post-operative day five.The resection margin was 14 millimeters.
