laparoscopic left lateral sectionectomy: guided by the ligamentum teres hepatis and the umbilical fissure vein

Laparoscopic techniques are extensively used in liver surgery and are considered safe and effective. Compared with open surgery, laparoscopic left lateral sectionectomy (LLLS) offers several advantages, including a reduced overall complication rate, shorter postoperative hospitalization, and decreased blood loss1. In the traditional LLLS procedure, the parenchyma is dissected using a harmonic scalpel, starting on the upper liver surface, proceeding from front to back, taking layers 2-3 mm deep ventral and dorsal to the level of the LHV, followed by direct dissection of the left outer lobe hepatic hilum with a staple2. This method may lead to injury of the hepatic parenchyma and veins, thereby increasing the risk of bleeding. The controlled low central venous pressure (CLCVP) technique is often employed in traditional LLLS procedures to mitigate intraoperative bleeding3. However, in patients with concurrent cardiovascular and cerebrovascular diseases, anesthesiologists may opt to avoid using the CLCVP technique to prioritize the perfusion of vital organs4. Herein, we present a standardized procedure for LLLS that does not rely on the CLCVP technique but effectively manages intraoperative bleeding. The key components of the procedure are as follows: (1) utilizing the ligamentum teres hepatis (LTH) approach to control the Glissonian pedicles for segments 2/3; (2) determining the transection plane of the liver based on anatomical landmarks such as the falciform ligament, umbilical fissure vein (UFV), and the canal of Arantius; and (3) using the UFV as a guide for hepatic parenchymal transection to enhance accessibility to the root of the left hepatic vein. The rationale for this technique, which is guided by anatomical landmarks such as the Glissonian pedicle and intrahepatic veins (e.g., UFV), enables more precise lobular and segmental resections while reducing the risk of hemorrhage5. This procedure is straightforward and easy to disseminate and learn. Xie et al.6 and Prof. Sugioka et al.7 have highlighted the safety, effectiveness, simplicity, and anatomical correctness of the LTH approach in hepatectomy procedures. We introduced the LLLS procedure guided by LTH and UFV to further improve the surgical technique.
In this study, we present a representative case to elucidate the procedural steps involved. A 74-year-old male patient presented with chronic upper abdominal pain that had persisted for 3 months. Pre-operative magnetic resonance imaging (MRI) revealed left intrahepatic bile duct stones and localized cystic dilatation of the bile ducts (Figure 1A,B). Additionally, the patient had a history of two cerebral infarctions. Head MRI indicated multiple ischemic and infarct lesions in various brain regions, including the bilateral periventricular regions, basal ganglia, corona radiata, brainstem, and frontal lobes. Notably, lesions in the left basal ganglia and adjacent parts of the right lateral ventricle softened with gliosis. The patient&#39;s Child-Pugh score was 5 (Grade A), and indocyanine green (ICG) retention at 15 min was 6.5%. Based on the radiological features, the patient was diagnosed with left intrahepatic bile duct stones. Subsequently, the patient underwent LLLS.

Laparoskopische Sektionektomie linkslateral: Geführt durch das Ligamentum teres hepatis und die Nabelfissurenvene

My research focuses on minimally invasive surgical treatments for hepatobiliary and pancreatic tumors. Guided by ligamentum teres hepatis and umbilical fissure vein, this laparoscopic left lateral sectionectomy procedure effectively controls intraoperative bleeding, even in the absence of controlled low central venous pressure. These attributes offer the potential benefit for patients with cardiovascular or cerebrovascular conditions.Advanced imaging modalities, such as indocyanine green fluorescence imaging, can provide real-time visualization of biliary anatomy, aiding in surgical planning and decision making. The advantage of our technique is that it avoids hepatic hilar dissection. Second, during liver parenchymal dissection, we utilize the intrahepatic anatomic landmark of the umbilical fissure vein as a guide to prevent loss of direction.
