Objective To explore the effects of different time spans for off-bed activities on postoperative rehabiliatioin of patients with liver transplantation. Methods The clinical data of 42 patients having undergone allogeneic liver transplantation during Jan. 2014 to Oct. 2015 were assigned as the observation group. Another 44 patitents during the same period , matched to those in the observation group in terms of general data , were assigned as the control group . The clinical data of two groupos were reviewed to make comparisons in terms of the time for anus exhaust , the time spans for gastric tube and urinary catheter indwelling , abdominal cavity effusion and hemorrhage and pulmonary infection 3 days after operation. Result The time for anus exhaust and the time spans for gastric tube and urinary catheter indwelling in the observation group were all significantly shorter than the control gorup (P<0.05), but there were insignifiant differences between the groups in abdominal cavity effusion and hemorrhage and pulmonary infection. Conclusion Off-bed activities 3 days after operation is safe and feasible for the patients having undergone allogeneic liver transplantation. It can promote their process of rehabilitation.

Objective To investigate the nursing of the adult recipients who accept children organ donations after cardiac death(DCD)complicated with portal venous thrombosis after liver transplantation. Methods We retrospectively analyzed 1 case completed in 2015 related to the adult recipients who accept children organ donations after cardiac death with portal venous thrombosis after liver transplantation in clinical situation,in view of the portal vein thrombosis of portal vein catheter thrombolysis,portal vein carotid stenting, close observation and nursing are used for patients′condition change. Results After positive clinical therapy and careful nursing,portal venous thrombolysis effect is good, and portal venous blood flowing after carotid stenting,clinical symptoms were alleviated. The liver function recovered well after surgery, and the patient discharged successfully,followed by regular visits from the hospital. Conclusions Children organ donations after cardiac death for liver can be successfully applied in the adult recipients,but the understanding of related complications after surgery need to be strengthened.The symptom observation,early detection,active nursing intervention,are conducive to the prognosis of patients.

Objective:
To investigate the application value of augmented reality (AR) technology in pancreatoduodenectomy (PD).
Methods:
The retrospective and descriptive study was conducted. The clinicopathological data of 3 male patients who underwent PD in Tsinghua University Affiliated Beijing Tsinghua Changgung Hospital from June 2018 to February 2019 were collected. The 3 patients were aged from 52 to 63 years, with a median age of 57 years. Digital imaging and communication standard format data of enhanced computed tomography (CT) scan were collected, the three-dimensional (3D) images of abdominal arteries, portal vein, descending duodenum, pancreatic body and tail, pancreatic head, common bile duct, and pancreatic duct were reconstructed. The results were imported into the AR software. Optical tracking based on two-dimensional codes and manual interactive rigid registration were adopted for intraoperative navigation. Observation indicators: (1) surgical and postoperative conditions; (2) postoperative pathological examination; (3) follow-up. Follow-up using outpatient examination or telephone interview was conducted to detect survival of patients and tumor metastasis and recurrence up to June 2019. The measurement data with skewed distribution were expressed as

Objective To analyze three-dimensional imaging characteristics and advantages for severe portal vein stenosis after liver transplantation, and to evaluate clinical efficacy of portal vein stent implantation. Methods Clinical data of 10 patients who received portal vein stent implantation for severe portal vein stenosis after liver transplantation were retrospectively analyzed. Imaging characteristics of severe portal vein stenosis, and advantages of three-dimensional reconstruction imaging and interventional treatment efficacy for severe portal vein stenosis were analyzed. Results Among 10 patients, 3 cases were diagnosed with centripetal stenosis, tortuosity angulation-induced stenosis in 2 cases, compression-induced stenosis in 2 cases, long-segment stenosis and/or vascular occlusion in 3 cases. Three-dimensional reconstruction images possessed advantages in accurate identification of stenosis, identification of stenosis types and measurement of stenosis length. All patients were successfully implanted with portal vein stents. After stent implantation, the diameter of the minimum diameter of portal vein was increased [(6.2±0.9) mm vs. (2.6±1.7) mm, P<0.05], the flow velocity at anastomotic site was decreased [(57±19) cm/s vs. (128±27) cm/s, P<0.05], and the flow velocity at the portal vein adjacent to the liver was increased [(41±6) cm/s vs. (18±6) cm/s, P<0.05]. One patient suffered from intrahepatic hematoma caused by interventional puncture, which was mitigated after conservative observation and treatment. The remaining patients did not experience relevant complications. Conclusions Three-dimensional visualization technique may visually display the location, characteristics and severity of stenosis, which is beneficial for clinicians to make treatment decisions and assist interventional procedures. Timely implantation of portal vein stent may effectively reverse pathological process and improve portal vein blood flow.

Objective To summarize the diagnosis and treatment experience of portal vein aneurysm after liver transplantation. Methods Clinical data of two recipients with portal vein aneurysm after liver transplantation were retrospectively analyzed. Clinical features, diagnosis, treatment and prognosis were summarized based on literature review. Results Both two cases were diagnosed with intrahepatic portal vein aneurysm complicated with portal vein thrombosis and portal hypertension after liver transplantation. Case 1 was given with targeted conservative treatment and he refused to undergo liver retransplantation. Physical condition was worsened after discharge, and the patient eventually died from liver graft failure, kidney failure, lung infection, and septic shock. Case 2 received high-dose glucocorticoid pulse therapy, whereas liver function was not improved, and the patient was recovered successfully after secondary liver transplantation. Conclusions Long-term complication of portal vein aneurysm (especially intrahepatic type) after liver transplantation probably indicates poor prognosis. Correct understanding, intimate follow-up and active treatment should be conducted. Liver retransplantation may be a potential treatment regimen.
