“…3D laparoscopy is the latest development of laparoscopic surgery and has been shown to improve surgical outcomes, reduce errors, enhance spatial awareness, and reduce the time required to complete surgical tasks in a laboratory environment [32,33]. The popularity of 3D technology is gradually increasing, and its advantages are more pronounced in the visualization and distribution of solid organs [34]. Using 3D technology, surgeons can focus on the speci c anatomical structures of a patient's organ and predict the various stages of the operation [34].…”

Objective: To investigate the effect of self-made liver suspension device in 3D laparoscopic non-anatomical resection of liver VI and VII segments tumors. Methods: The clinical data of 79 patients who underwent non-anatomical resection of liver VI and VII segments tumors at the Second Hospital of Hebei Medical University from June 2016 to June 2022 were retrospectively analyzed, divided into SDLG group and CLG group. The SDLG group used the self-made liver suspension device for 3D laparoscopic resection, and the CLG group received conventional 3D laparoscopic resection; the clinical data were compared to evaluate the efficacy. Results: The operation time in SDLG group was significantly shorter than that in CLG group, the intraoperative bleeding volume and liver portal blockage time were significantly reduced, and the postoperative complications were alleviated; there was no significant difference in hospital stay, drainage tube removal time, bedside time, and postoperative flatus time. Conclusion: The self-made liver suspension device can shorten the operation time and liver portal blockage time, reduce intraoperative bleeding, alleviate postoperative complications, and improve the safety of non-anatomical resection of liver VI and VII segments tumors. It is worth further clinical promotion.

“…Knowledge of a given patient’s liver anatomy is essential for approaching resection in a strategical manner, considering probable future repeated surgery, advocating, when possible, the use of a parenchyma-sparing strategy [ 19 ] to preserve liver function and the liver parenchyma. Three-dimensional reconstruction could be a useful tool for planning resection, considering the anatomical variations of patients [ 20 , 21 ], facilitating the parenchyma-sparing approach by enabling a high level of precision in surgery [ 13 , 22 ] and exploiting cone unit dissection [ 23 ]. Laparoscopic surgery has entered this developing surgery, enabling the use of indocyanine green fluorescence [ 24 ] to perform anatomical resection by cone dissection, in combination with high-level technology, to perform complex liver resection [ 25 ].…”

When colorectal cancer presents with liver metastasis, hepatic resection remains the most important factor in prolonging survival, and new paradigms have been proposed to augment resectability. An adequate liver remnant and vascularisation are the only limits in complex liver resection, and parenchyma-sparing surgery is a strategy for minimising the complications, preserving liver function, and allowing patients to undergo further liver resection. The laparoscopic approach represents a new challenge, especially when lesions are located in the superior or posterior part of the liver. We discuss the case of an 81-year-old patient with a single synchronous liver metastasis involving the left hepatic vein and leaning into the middle hepatic vein at the common trunk, where we performed a simultaneous laparoscopic colonic resection with a left sectionectomy extended to segment 4a. The strategic approach to the Arantius ligament by joining the left and middle hepatic vein allowed us to avoid a major liver hepatectomy, preserve the liver parenchyma, reduce complications, enhance patient recovery, and perform the entire procedure by laparoscopy. Our example suggests that the Arantius approach to the left hepatic vein and the common trunk could be a feasible approach to consider in laparoscopic surgery for lesions located in their proximity.

Hyper accuracy three-dimensional (HA3D™) technology for planning complex liver resections: a preliminary single center experience

et al. 2022

Three-dimensional visualization technology (3DVT) has been recently introduced to achieve a precise preoperative planning of liver surgery. The aim of this observational study was to assess the accuracy of 3DVT for complex liver resections. 3DVT with hyper accuracy three-dimensional (HA3D™) technology was introduced at our institution on February 2020. Anatomical characteristics were collected from two-dimensional imaging (2DI) and 3DVT, while intraoperative and postoperative outcomes were recorded prospectively. A total of 62 patients were enrolled into the study. 3DVT was able to study tumor extension and liver anatomy, identifying at least one vascular variation in 37 patients (59.7%). Future remnant liver volume (FRLV) was measured using 2DI and 3DVT. The paired samples t test assessed positive correlation between the two methods (p < 0.001). At least one vessel was suspected to be invaded by the tumor in 8 (15.7%) 2DI cases vs 16 (31.4%) 3DVT cases, respectively. During surgery, vascular invasion was detected in 17 patients (33.3%). A total of 73 surgical procedures were proposed basing on 2DI, including 2 alternatives for 16 patients. After 3DVT, the previously planned procedure was changed in 15 cases (29.4%), due to the clearer information provided. A total of 51 patients (82%) underwent surgery. The most frequent procedure was right hepatectomy (33.3%), followed by left hepatectomy (23.5%) and left trisectionectomy (13.7%). Vascular resection and reconstruction were performed in 10 patients (19.6%) and portal vein was resected in more than half of these cases (66.7%). 3DVT leads to a more detailed and tailored approach to complex liver surgery, improving surgeons’ knowledge of liver anatomy and accuracy of liver resection.
