Background: Early detection and grading of pancreatic fibrosis (PF) are important and challenging clinical goals. Purpose: To determine main pancreatic duct (MPD) diameter, pancreatic thickness, and grades of PF via magnetic resonance elastography (MRE), T1 mapping, and intravoxel incoherent motion diffusion-weighted imaging (IVIM-DWI), assessing respective diagnostic performances. Study Type: Prospective. Subjects: Histopathologic and imaging records (MRE, T1 mapping, and IVIM-DWI) generated by 144 patients between December 2018 and May 2020 were collected for analysis. Grades of PF were distributed as follows:

Aim: To explore the value and prospects of the combined vessel resection with reconstruction techniques in space-occupying lesion surgical treatment. Method: We collected and analyzed clinical data of patients received combined with vessel resection and reconstruction techniques surgery in department of hepatobiliary surgery in our hospital from May 2007 to November 2012, and concluded experience in application of vessel resection and artificial vessel reconstruction. Result: A total of 12 cases were collected. 9 of them were pancreatic lesion, and the other 3 were liver Echinococcus granulosus. The average operative time of 12 cases was 6.1 ± 1.8 h, and the average blood loss was 385 ± 202 ml. The average intraoperative portal vein occlusion time was 31 ± 13 min. 1 case suffered intraperitoneal hemorrhage within 48 h after surgery and other 2 suffered pancreatic fistula. All of them were treated and cured; there was no infection, thrombosis and other complications and perioperative deaths turned up before discharge. 4 cases of pancreatic cancer patients after 4, 9, 35 and 37 died of tumor recurrence and metastasis: 1 was lost and the rest are all alive. The follow-up time of these cases was 3-58 months with an average level of 22.4 months. Conclusion: Occupying lesions that cannot achieve traditional radical resection due to vessel invasion conventional radical resection may be cured by combining with vessel resection and reconstruction of the lesion resection surgery, and with good prospects worthy of promotion and application of clinic; this technique should be applied to lesion in hepatobiliary system.
