ARTICLE HIGHLIGHTS
Research background

The incidence of hilar cholangiocarcinoma (HCCA) has shown a significant upward trend, and radical surgery is an effective treatment. However, the complexity of the anatomical structure of the hilar bile duct and blood vessels, the invasion of the adjacent blood vessels of the tumor, jaundice, and the scope of hepatectomy have resulted in a low resection rate for HCCA and poor prognosis.

Research motivation

The preoperative evaluation of HCCA mainly relies on traditional computed tomography and magnetic resonance imaging. Surgeons need to construct 2D images into 3D models in their minds based on clinical experience and anatomical knowledge. Such a method is subjective and will affect the formulation of surgical plans.

Research objectives

This study aimed to establish a laparoscopic precise resection of HCCA based on preoperative eOrganmap 3D reconstruction and full quantification technology, to provide a new method for precise treatment of HCCA.

Research methods

We retrospectively analyzed the clinical data of 73 patients with HCCA who underwent surgery. Patients were divided into the traditional group (2D imaging planning before surgery) and eOrganmap group (3D reconstruction and full quantification technology planning before surgery). To compare the relevant indicators of the two groups of patients and to further explore the difference between eOrganmap 3D reconstruction and full quantification technology and traditional 2D image planning treatment.

Research results

eOrganmap 3D reconstruction and full quantification technology planning have obvious advantages in classification accuracy, blood loss, operating time, postoperative intestinal ventilation time, R0 resection rate, number of lymph nodes dissected, total complication rate, and liver function. In the eOrganmap group, there was a high correlation between the volume of the actual resected liver specimen and the volume of the virtual resected liver specimen before the operation.

Research conclusions

Establishing laparoscopic precise resection of hilar cholangiocarcinoma based on preoperative eOrganmap 3D reconstruction and full quantification technology can make laparoscopic HCCA resection more accurate and safe.

Research perspectives

The results of this study were verified by a retrospective study with a large sample size, which enhanced the reliability of the results and contributed to the clinical promotion of eOrganmap 3D reconstruction and full quantification technology.
