The protocol follows the guidelines of the Human Research Ethics Committee of Nanchong Central Hospital.
1. Pre-operative workup
<ol>
	<li>Perform MRI scanning to confirm the diagnosis and assess the extent of the lesion, bile duct, and vascular anatomy. Perform a magnetic resonance cholangiopancreatography imaging scan on a 3.0 T MRI unit using T2 weighted image thick single-shot fast spin echo/turbo spin echo and fast acquisition relaxation enhancement sequences (Table of Materials).</li>
	<li>Perform the ICG retention test to effectively assess liver function.
	<ol>
		<li>Utilize the liver function reserve analyzer for experimental analysis. Input the patient&#39;s height, body weight, and hemoglobin concentration on the analyzer&#39;s touch screen. The software will automatically compute the required amount of ICG to be injected.</li>
		<li>Subsequently, rapidly inject the ICG through the left median cubital vein, while the nasal probe automatically measures the wavelength of the spectrophotometric spectra. Employ spectroscopic analysis to determine the concentration of ICG, followed by calculating the retention rate after a 10-min injection period8 (Table of Materials).</li>
	</ol>
	</li>
	<li>Extend invitations to surgical, anesthesiology, neurology, and cardiology experts for multidisciplinary consultation to develop surgical strategies, anesthesia management plans, and perioperative medication guidelines.</li>
</ol>
2. Anesthesia
<ol>
	<li>Administer pre-operative antibiotics, typically 1.0 g of ceftazidime (Table of Materials), intravenously on induction of anesthesia.</li>
	<li>Place an arterial line in the patient&#39;s left radial artery and insert a central venous line into the right internal jugular vein.</li>
	<li>Control the intraoperative central venous pressure (CVP) at 5-10 mmHg to ensure cerebral blood perfusion and avoid intraoperative hypotension.</li>
</ol>
3. Patient positioning
<ol>
	<li>Position the patient supine on the operating table in a split-leg position, with the camera assistant standing between the patient&#39;s legs, the first assistant on the patient&#39;s left side, and the surgeon on the patient&#39;s right side.</li>

Management of intraoperative bleeding remains a crucial challenge in laparoscopic hepatectomy. To address this issue, Pringle&#39;s maneuver and the CLCVP technique are commonly employed to control hepatic blood flow10. However, not all patients are suitable candidates for CLCVP, particularly those with concurrent cardiovascular and cerebrovascular diseases.
In this study, we present our experience with laparoscopic hepatectomy in patients with comorbid cerebrovascular ...

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.

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

Laparoscopic left lateral sectionectomy (LLLS), a mainstream procedure in liver surgery, often utilizes controlled low central venous pressure (CLCVP) to reduce bleeding in the hepatic venous system. However, anesthesiologists may avoid the use of CLCVP in patients with concurrent cardiovascular and cerebrovascular diseases to prioritize the maintenance of vital organ perfusion. In this report, we present an LLLS guided by the ligamentum teres hepatis (LTH) for dissection of the Glissonian pedicles for segments 2/3 outside the liver, followed by hepatic parenchymal dissection along the falciform ligament and umbilical fissure vein (UFV) while approaching the left hepatic vein root. Guided by LTH and UFV, this LLLS procedure effectively controlled intraoperative bleeding, even in the absence of CLCVP. Additionally, hepatectomy guided by extrahepatic and intrahepatic anatomical landmarks prevents loss of direction during liver dissection and ensures precise hepatic resection. These attributes suggest that the potential benefits extend beyond patients with cardiovascular or cerebrovascular conditions, making it applicable in a wide range of LLLS cases.
