Study Arms (2)

laparoscopic surgery

EXPERIMENTAL

The laparoscopic view is caudal to cephalic, which is consistent with the direction of hepatic transection. In addition, the high-definition magnified view and ability to change perspectives with the laparoscope are conducive to subtle manipulation, and compression of the carbon dioxide pneumoperitoneum can reduce venous bleeding. Therefore, laparoscopic surgery may have certain advantages in the treatment of paracaval-originating lesions.

Procedure: laparoscopic surgery

Open surgery

ACTIVE COMPARATOR

Open surgery is the traditional surgical method for resection of paracaval-originating lesions.

Procedure: Open surgery

Interventions

Patients were supine in a reverse Trendelenburg position and received intravenous inhalation combined with anesthesia. The patients' legs were spread apart. A carbon dioxide pneumoperitoneum was established. The intermittent Pringle's maneuver was carried out when necessary. Five trocars were placed in a fan shape around the lesion. Cholecystectomy was performed routinely. First, the liver was mobilized. Then, the liver parenchyma was transected and the branches of the hepatic veins and pedicles encountered were clipped and divided. The lesion was meticulously separated from the vascular structures and liver parenchyma and completely resected. The raw surface was treated with bipolar coagulation to achieve hemostasis and repeatedly washed until no bleeding or bile leakage was confirmed. Finally, the specimens were packed in a specimen bag and removed. The raw surface was packed with biological hemostatic materials, and drainage tubes were routinely placed.

Patients were placed in the supine position and received intravenous inhalation combined with anesthesia. The intermittent Pringle's maneuver was carried out when necessary. Routinely, a reversed L-shape incision was performed. Cholecystectomy was performed routinely. First, the liver was mobilized. Then, the liver parenchyma was transected and the branches of the hepatic veins and pedicles encountered were clipped and divided. The lesion was meticulously separated from the vascular structures and liver parenchyma and completely resected. The raw surface was treated with bipolar coagulation to achieve hemostasis and repeatedly washed until no bleeding or bile leakage was confirmed. Finally, the specimens were packed in a specimen bag and removed. The raw surface was packed with biological hemostatic materials, and drainage tubes were routinely placed.
