Application of 3D reconstruction for surgical treatment of hepatic alveolar echinococcosis

Abstract

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.

Magnetic resonance imaging evaluation of characteristics of vascular invasion in intermediate and advanced hepatic alveolar echinococcosis

“…However, radical resection may be difficult, as the parasite exhibits an invasive growth and tends to invade intrahepatic vessels in particular (8). Thus, accurate pre-operative assessment of a patient's vascular invasion status is key to successful surgery (9). Relatively few studies have focused on the vascular invasion status, and even fewer have addressed the physiological characteristics of vascular invasion.…”

Evaluation of a large adrenal carcinoma with 3D reconstruction of computed tomography images: A case report and literature review

“…With the aid of 3D reconstruction technology [13], tumor tissue could be precisely evaluated to help make appropriate surgery plan [10]. More applications of 3D reconstruction of CT data have been reported (Table 1) [19][20][21][22][23][24]. The 3D dynamic videos of target organs can be not only acted as an optimal diagnostic approach for surgery but also be as a better learning tool for residents or medical students.…”

Quantitative evaluation of range and metabolic activity of hepatic alveolar echinococcosis lesion microenvironment using PET/CT and multi-site sampling method

“…MSS samples were acquired from surgical specimens. The speci c sampling site were preoperatively planned through spatial information based on CT and PET/CT, even using three-dimensional reconstruction techniques [13,14]. First, liver specimens which contained the target lesion (approximately 1 cm at thickness) as well as adherent liver tissue (at least for 5 cm at length) were cut into size about 2cm*3cm*6cm, and xed with formalin immediately.…”
