| 1 | Up-to-date intraoperative computer assisted solutions for liver surgery显示文摘Computer assisted surgical planning allowed for a better selection of patients,evaluation of operative strategy, appropriate volumetric measurements,identification of anatomical risks, definition of tumour resection margins and choice of surgical approach in liver oncologic resections and living donor liver transplantations. Although preoperative computer surgical analysis has been widely used in daily clinical practice, intraoperative computer assisted solutions for risk analysis and navigation in liver surgery are not widely available or still under clinical evaluation. Computer science technology can efficiently assist modern surgeons during complex liver operations, mainly by providing image guidance with individualized 2 D images and 3 D models of the various anatomical and pathological structures of interest. Intraoperative computer assisted liver surgery is particularly useful in complex parenchyma-sparing hepatectomies, for intraoperative risk analysis and for the effective treatment of colorectal metastases after neoadjuvant therapy or when they are multiple. In laparoscopic liver surgery, intraoperative computer aid is definitively more important as, apart from a restricted field of view, there is also loss of the fine haptic feedback. Intraoperative computer assisted developments face challenges that prevent their application in daily clinical practice. There is a vast variety of studies regarding intraoperative computer assisted liver surgery but there are no clear objective measurements in order to compare them and select the most effective solutions. An overview of up-to-date intraoperative computer assisted solutions for liver surgery will be discussed. | Apollon Zygomalas Ioannis Kehagias | 2019 | World Journal of Gastrointestinal Surgery2019，11，1： | 3 |
| 2 | Computer planned, image-guided combined resection and ablation for bilobar colorectal liver metastases显示文摘For patients with extensive bilobar colorectal liver metastases(CRLM),initial surgery may not be feasible and a multimodal approach including microwave ablation(MWA)provides the only chance for prolonged survival.Intraoperative navigation systems may improve the accuracy of ablation and surgical resection of so-called'vanishing lesions',ultimately improving patient outcome.Clinical application of intraoperative navigated liver surgery is illustrated in a patient undergoing combined resection/MWA for multiple,synchronous,bilobar CRLM.Regular follow-up with computed tomography(CT)allowed for temporal development of the ablation zones.Of the ten lesions detected in a preoperative CT scan,the largest lesion was resected and the others were ablated using an intraoperative navigation system.Twelve months post-surgery a new lesion(SegⅣa)was detected and treated by trans-arterial embo-lization.Nineteen months post-surgery new liver and lung metastases were detected and a palliative chemotherapy started.The patient passed away four years after initial diagnosis.For patients with extensive CRLM not treatable by standard surgery,navigated MWA/resection may provide excellent tumor control,improving longer-term survival.Intraoperative navigation systems provide precise,real-time information to the surgeon,aiding the decision-making process and substantially improving the accuracy of both ablation and resection.Regular follow-ups including 3D modeling allow for early discrimination between ablation zones and recurrent tumor lesions. | Vanessa M Banz Matthias Baechtold Stefan Weber Matthias Peterhans Daniel Inderbitzin Daniel Candinas | 2014 | World Journal of Gastroenterology2014，20，40： | 2 |
