“…The preoperative liver volume measurements based on 3D anatomy imaging have been shown to agree with the actual volume of the liver resected at operation (17)(18)(19). The median volume difference between the portalvein-based and hepatic-vein-based anatomies in S6 was 73 mL.…”

“…RFS and CSS were significantly worse in the LR group than in the AR group. However, our results suggest that LR may leave some In this context, recent advances in 3D-diagnostic imaging may be advantageous [31] . If 3D technology could be enhanced to a degree that enables it to be as informative as laparotomy, allowing diagnosis of cirrhosis before surgery, and if it were able to visualize the portal vein and provide details of the main branch feeding the tumor, it might become possible to consider extended LR or modified subsegmentectomy instead of uniform resection with a 2-cm margin [32,33] .…”

Background: Hepatic resection for hepatocellular carcinoma (HCC) is now established as the treatment most likely to yield the best outcome. We aimed to clarify the risk factors for HCC recurrence after curative resection of single HCC in patients with normal liver function (NLF). Methods: The clinical records of 105 patients with NFL and a single HCC less than 5 cm in diameter who had undergone curative liver resection between April 2000 and January 2013 were investigated. We analyzed risk factors for recurrence of HCC. Results: Forty of the 105 patients suffered recurrence of HCC, and median recurrence-free survival (RFS) was 22.0 (5.1-148.5) months after surgery, and the liver was the most frequent site of recurrence. Univariate analysis showed that limited resection (LR; p = 0.002), the indocyanine green retention rate at 15 min (p = 0.023), C-reactive protein value (p = 0.001), bilirubin value (p = 0.042), neutrophil to lymphocyte ratio (p = 0.042), operation time (p = 0.018), and amount of bleeding (p = 0.011) were associated with RFS. Multivariate analysis showed that LR (p = 0.007) was a significant risk factor associated with RFS. Conclusion: LR is a risk factor for HCC recurrence in patients with single-lesion HCC and NLF.

“…The 3D reconstruction system allows surgeons to perform virtual surgery on the 3D model of a liver, which maximizes the human-computer interaction in the course of medical treatment [24,25] . The process is helpful for surgeons to understand fully the specific details about key parts [26,27] . The occurrence of intraoperative incidents, such as biliary and vascular injuries, bleeding, and bile leakage, can be effectively prevented by designing different resection planes and optimizing surgical strategies [28,29] .…”

AIM:To evaluate the reliability and accuracy of threedimensional (3D) reconstruction for liver resection in patients with hepatic alveolar echinococcosis (HAE). METHODS:One-hundred and six consecutive patients with HAE underwent hepatectomy at our hospital between May 2011 and January 2015. Fifty-nine patients underwent preoperative 3D reconstruction and "virtual" 3D liver resection before surgery (Group A). Another 47 patients used conventional imaging methods for preoperative assessment (Group B). Outcomes of hepatectomy were compared between the two groups. RESULTS:There was no significant difference in preoperative data between the two groups. groups had good correlation with actual graft weight (Group A: r = 0.978; Group B: r = 0.960). There was a significant higher serum level of albumin in Group A (26.3 ± 5.9 vs 22.6 ± 4.3 g/L, P < 0.05). Other postoperative laboratory parameters (serum levels of aminotransferase and bilirubin; prothrombin time) and duration of postoperative hospital stay were similar. Sixteen complications occurred in Group A and 19 in Group B. All patients were followed for 3-46 (mean, 17.3) mo. There was no recurrence of lesions in Group A, but two recurrences in Group B. There were three deaths: two from cerebrovascular accident, and one from car accident. CONCLUSION:3D reconstruction provides comprehensive and precise anatomical information for the liver. It also improves the chance of success and reduces the risk of hepatectomy in HAE. Core tip: With the rapid development of digital medicine, three-dimensional (3D) reconstruction software has become a new tool in surgery, and it is a quantitative imaging analysis system that provides real-time interactive tools for presurgical evaluation and planning. We compared the clinical results of hepatectomy for hepatic alveolar echinococcosis based on 3D software with traditional assessment. We found that liver resection based on 3D reconstruction was more effective in the diagnosis and treatment of HAE than techniques without 3D reconstruction. Such 3D reconstruction software for preoperative evaluation and surgical planning could increase the chance of success of surgery and reduce operative risk.
