| 1 | Intraoperative cell salvage with autologous transfusion in liver transplantation显示文摘Liver transplant(LT) is the primary treatment for patients with end-stage liver disease. About 25000 LTs are performed annually in the world. The potential for intraoperative bleeding is quite variable. However, massive bleeding is common and requires blood transfusion. Allogeneic blood transfusion has an immunosuppressive effect and an impact on recipient survival, in addition to the risk of transmission of viral infections and transfusion errors, among others.Techniques to prevent excessive bleeding or to use autologous blood have been proposed to minimize the negative effects of allogeneic blood transfusion.Intraoperative reinfusion of autologous blood is possible through previous selfdonation or blood collected during the operation. However, LT does not normally allow autologous transfusion by prior self-donation. Hence, using autologous blood collected intraoperatively is the most feasible option. The use of intraoperative blood salvage autotransfusion(IBSA) minimizes the perioperative use of allogeneic blood, preventing negative transfusion effects without negatively impacting other clinical outcomes. The use of IBSA in patients with cancer is still a matter of debate due to the theoretical risk of reinfusion of tumor cells. However, studies have demonstrated the safety of IBSA in several surgical procedures, including LT for hepatocellular carcinoma. Considering the literature available to date, we can state that IBSA should be routinely used in LT, both in patients with cancer and in patients with benign diseases. | Marcelo A Pinto Marcio F Chedid Leo Sekine Andre P Schmidt Rodrigo P Capra Carolina Prediger Jo?o E Prediger Tomaz JM Grezzana-Filho Cleber RP Kruel | 2019 | World Journal of Gastrointestinal Surgery2019，11，1： | 16 |
| 2 | Hepatic ischemic preconditioning increases portal vein flow in experimental liver ischemia reperfusion injury显示文摘BACKGROUND: Ischemic preconditioning(IPC) has been shown to decrease liver injury and to increase hepatic microvascular perfusion after liver ischemia reperfusion. This study aimed to evaluate the effects of IPC on hemodynamics of the portal venous system. METHODS: Thirty-two rats were randomized into two groups: IPC group and control group. The rats of the IPC group underwent IPC by 10 minutes of liver ischemia followed by 10 minutes of reperfusion before liver ischemia, and the rats of the control group were subjected to 60 minutes of partial liver ischemia. Non-ischemic lobes were resected immediately after reperfusion. The animals were studied at 4 hours and 12 hours after reperfusion. Mean arterial pressure, heart rate, portal vein flow and pressure were analyzed. Blood was collected for the determination of the levels of aspartate aminotransferase, alanine aminotransferase, calcium, lactate, pH, bicarbonate, and base excess. RESULTS: IPC increased the mean portal vein flow at 4 hours and 12 hours after reperfusion. IPC recovered 78% of the meanportal vein flow at 12 hours after reperfusion. IPC decreased the levels of aspartate aminotransferase, alanine aminotransferase and lactate, and increased the levels of ionized calcium, bicarbonate and base excess at 12 hours after reperfusion. CONCLUSIONS: This study demonstrated that IPC increases portal vein flow and enhances hepatoprotective effects in liver ischemia reperfusion. The better recovery of portal vein flow after IPC may be correlated with the lower levels of transaminases and with the better metabolic profile. | Estela RR Figueira Joel A Rocha-Filho Mauro Nakatani Marcelo FS Buto Eduardo R Tatebe Vitor O Andre Ivan Cecconello Luiz AC D'Albuquerque | 2014 | Hepatobiliary & Pancreatic Diseases International2014，13，1： | 6 |

| 11 | Simultaneous follow-up of mouse colon lesions by colonoscopy and endoluminal ultrasound biomicroscopy显示文摘AIM:To evaluate the potential use of colonoscopy and endoluminal ultrasonic biomicroscopy(eUBM)to track the progression of mouse colonic lesions.METHODS:Ten mice were treated with a single azoxy-methane intraperitoneal injection(week 1)followed by seven days of a dextran sulfate sodium treatment in their drinking water(week 2)to induce inflammationassociated colon tumors.eUBM was performed simultaneously with colonoscopy at weeks 13,17-20 and21.A 3.6-F diameter 40 MHz mini-probe catheter was used for eUBM imaging.The ultrasound mini-probe catheter was inserted into the accessory channel of a pediatric flexible bronchofiberscope,allowing simultaneous acquisition of colonoscopic and eUBM images.During image acquisition,the mice were anesthetized with isoflurane and kept in a supine position over a stainless steel heated surgical waterbed at 37℃.Both eUBM and colonoscopic images were captured and stored when a lesion was detected by colonoscopy or when the eUBM image revealed a modified colon wall anatomy.During the procedure,the colon was irrigated with water that was injected through a flush port on the mini-probe catheter and that acted as the ultrasound coupling medium between the transducer and the colon wall.Once the acquisition of the last eUBM/colonoscopy section for each animal was completed,the colons were fixed,paraffin-embedded,and stained with hematoxylin and eosin.Colon images acquired at the first time-point for each mouse were compared with subsequent eUBM/colonoscopic images of the same sites obtained in the following acquisitions to evaluate lesion progression.RESULTS:All 10 mice had eUBM and colonoscopic images acquired at week 13(the first time-point).Two animals died immediately after the first imaging acquisition and,consequently,only 8 mice were subjected to the second eUBM/colonoscopy imaging acquisition(at the second time-point).Due to the advanced stage of colonic tumorigenesis,5 animals died after the second time-point image acquisition,and thus,only three were subjected to the third eUBM/colonoscopy imaging acquisition(the third time-point).eUBM was able to detect the four layers in healthy segments of colon:the mucosa(the first hyperechoic layer moving away from the mini-probe axis),followed by the muscularis mucosae(hypoechoic),the submucosa(the second hyperechoic layer)and the muscularis externa(the second hypoechoic layer).Hypoechoic regions between the mucosa and the muscularis externa layers represented lymphoid infiltrates,as confirmed by the corresponding histological images.Pedunculated tumors were represented by hyperechoic masses in the mucosa layer.Among the lesions that decreased in size between the first and third time-points,one of the lesions changed from a mucosal hyperplasia with ulceration at the top to a mucosal hyperplasia with lymphoid infiltrate and,finally,to small signs of mucosal hyperplasia and lymphoid infiltrate.In this case,while lesion regression and modification were observable in the eUBM images,colonoscopy was only able to detect the lesion at the first and second time-points,without the capacity to demonstrate the presence of lymphoid infiltrate.Regarding the lesions that increased in size,one of them started as a small elevation in the mucosa layer and progressed to a pedunculated tumor.In this case,while eUBM imaging revealed the lesion at the first time-point,colonoscopy was only able to detect it at the second time-point.All colonic lesions(tumors,lymphoid infiltrate and mucosal thickening)were identified by eUBM,while colonoscopy identified just76%of them.Colonoscopy identified all of the colonic tumors but failed to diagnose lymphoid infiltrates and increased mucosal thickness and failed to differentiate lymphoid infiltrates from small adenomas.During the observation period,most of the lesions(approximately67%)increased in size,approximately 14%remained unchanged,and 19%regressed.CONCLUSION:Combining eUBM with colonoscopy improves the diagnosis and the follow-up of mouse colonic lesions,adding transmural assessment of the bowel wall. | Rossana C Soletti Kelly Z Alves Marcelo AP de Britto Dyanna G de Matos Mnica Soldan Helena L Borges Joo C Machado | 2013 | World Journal of Gastroenterology2013，19，44： | 1 |
