Abstract

Abstract:

Objective

To investigate the application of dorsal approach in laparoscopic resection of paracaval portion of the caudate lobe.

Methods

Clinical data of 6 patients undergoing laparoscopic resection of paracaval portion of the caudate lobe in the First Affiliated Hospital of Hunan Normal University from January 2020 to July 2023 were retrospectively analyzed. The informed consents of all patients were obtained and the local ethical committee approval was received. Among them， 2 patients were male and 4 female， aged （47±12） years. All patients underwent laparoscopic resection of paracaval portion of the caudate lobe via dorsal approach. Perioperative conditions and complications were observed.

Results

The operation time of 6 patients was （158±28） min. The occlusion time of porta hepatis was （40±16） min.Intraoperative blood loss was 147 （50±280） ml. No intraoperative blood transfusion was given. The length of postoperative hospital stay of 6 patients was 3.0-7.0 d， with a median of 5.3 d. No severe complications such as bleeding and bile leakage occurred after operation. Postoperative pathological examination showed that 2 cases were diagnosed with hepatic cavernous hemangioma with a diameter of 7.2 and 9.0 cm， 2 cases of focal nodular hyperplasia with a diameter of 5.2 and 5.9 cm， 1 case of hepatocellular carcinoma with a diameter of 2.7 cm and 1 case of intrahepatic cholangiocarcinoma with a diameter of 2.5 cm， respectively.

Conclusions

For experienced laparoscopic team， it is safe and feasible to perform laparoscopic resection of paracaval portion of the caudate lobe via dorsal approach for patients with benign paracaval tumors and eligible patients with malignant tumors after screening.
