1Preservation solutions used during abdominal transplantation:Current status and outcomes显示文摘Organ preservation remains an important contributing factor to graft and patient outcomes. During donor organ procurement and transportation, cellular injury is mitigated through the use of preservation solutions in conjunction with hypothermia. Various preservation solutions and protocols exist with widespread variability among transplant centers. In this review of abdominal organ preservation solutions, evolution of transplantation and graft preservation are discussed followed by classification of preservation solutions according to the composition of electrolytes, impermeants, buffers, antioxidants, and energy precursors. Lastly, pertinent clinical studies in the setting of hepatic, renal, pancreas, and intestinal transplantation are reviewed for patient and graft survival as well as financial considerations. In liver transplants there may be some benefit with the use of histidine-tryptophan-ketoglutarate(HTK) over University of Wisconsin solution in terms of biliary complications and potential cost savings. Renal grafts may experience increased initial graft dysfunction with the use of Euro-Collins thereby dissuading its use in support of HTK which can lead to substantial cost savings. University of Wisconsin solution and Celsior are favored in pancreas transplants given the concern for pancreatitis and graft thrombosis associated with HTK. No difference was observed with preservation solutions with respect to graft and patient survival in liver, renal, and pancreas transplants. Studies involving intestinal transplants are sparse but University of Wisconsin solution infused intraluminally in combination with an intra-vascular washout is a reasonable option until further evidence can be generated. Available literature can be used to ameliorate extensive variation across centers while potentially minimizing graft dysfunction and improving associated costs.Nicholas Latchana Joshua R Peck Bryan A Whitson Mitchell L Henry Elmahdi A Elkhammas Sylvester M Black 2015World Journal of Transplantation2015,5,4:5
2Predictors of double balloon endoscopy outcomes in the evaluation of gastrointestinal bleeding显示文摘AIM:To identify patients' characteristics associated with double balloon endoscopy(DBE)outcomes in investigation of obscure gastrointestinal bleeding(OGIB).METHODS:Retrospective study performed at an academic tertiary referral center.Evaluated endpoints were clinical factors associated with no diagnostic yield or non-therapeutic intervention of DBE performed for OGIB evaluation.RESULTS:We included fifty-five DBE between August 2010 and April 2012.The mean age of the sample was 67 with 32 males(58.2%).Twenty-four DBE had no diagnostic yield and 30 DBE did not require therapy.Non-diagnostic yield was associated with performing two or more DBE studies in one day [odds ratio(OR):13.72,P=0.008],absence of blood transfusions within a year of the DBE(OR:7.16,P=0.03)and absence of ulcers or arteriovenous malformations(AVMs)on prior esophagogastroduodenoscopy(EGD)or colonoscopy(OR:19.30,P=0.033).Non-therapeutic DBE was associated with performing two or more DBE per day(OR:18.579,P=0.007),gastrointestinal bleeding episode within a week of the DBE(OR:11.48,P=0.003),fewer blood transfusion requirements prior to DBE(OR:4.55,P=0.036)and absence of ulcers or AVMs on prior EGD or colonoscopy(OR:8.47,P=0.027).CONCLUSION:Predictors of DBE yield and therapeutic intervention on DBE include blood transfusion requirements,previous endoscopic findings and possibly endoscopist fatigue.Hisham Hussan Nicholas R Crews Caroline M Geremakis Soubhi Bahna Jennifer L LaBundy Christine Hachem 2014World Journal of Gastrointestinal Endoscopy2014,6,6:3
3Perioperative risk factors associated with delayed graft function following deceased donor kidney transplantation:A retrospective,single center study显示文摘BACKGROUND There is an abundant need to increase the availability of deceased donor kidney transplantation(DDKT)to address the high incidence of kidney failure.Challenges exist in the utilization of higher risk donor organs into what appears to be increasingly complex recipients;thus the identification of modifiable risk factors associated with poor outcomes is paramount.AIM To identify risk factors associated with delayed graft function(DGF).METHODS Consecutive adults undergoing DDKT between January 2016 and July 2017 were identified with a study population of 294 patients.The primary outcome was the occurrence of DGF.RESULTS The incidence of DGF was 27%.Under logistic regression,eight independent risk factors for DGF were identified including recipient body mass index≥30 kg/m^(2),baseline mean arterial pressure<110 mmHg,intraoperative phenylephrine administration,cold storage time≥16 h,donation after cardiac death,donor history of coronary artery disease,donor terminal creatinine≥1.9 mg/dL,and a hypothermic machine perfusion(HMP)pump resistance≥0.23 mmHg/mL/min.CONCLUSION We delineate the association between DGF and recipient characteristics of preinduction mean arterial pressure below 110 mmHg,metabolic syndrome,donorspecific risk factors,HMP pump parameters,and intraoperative use of phenylephrine.Nicholas V Mendez Yehuda Raveh Joshua J Livingstone Gaetano Ciancio Giselle Guerra George W Burke III Vadim B Shatz Fouad G Souki Linda J Chen Mahmoud Morsi Jose M Figueiro Tony M Ibrahim Werviston L DeFaria Ramona Nicolau-Raducu 2021World Journal of Transplantation2021,11,4:2
4胸腹主动脉瘤:杂交修复术结果显示文摘目的:胸腹主动脉瘤(TAAA)的治疗依然是外科中最富挑战性的工作,特别是存在退行性变动脉瘤的老年患者同时患肺疾病更是如此。这篇更新后的单中心报道是关于我们对高危TAAA患者采用完全内脏动脉去分支化结合动脉瘤腔内隔绝的杂交修复术经验。方法:从2005年3月—2012年6月间58名患者在单中心接受解剖外内脏血管去分支化及随后的动脉瘤腔内隔绝术。内脏旁路的中位数为4支,最初的33例采用同期手术方式,而最近的25例采用分期手术。结果:患者中位年龄为69.0岁,50%为女性,所有患者存在严重合并症而不适合传统开放修复术。平均主动脉直径(6.7±1.2)cm,30 d/住院病死率、脑卒中率、永久性轻瘫/截瘫率分别为9%、0%以及4%。最近25例分期手术患者的这三种并发症率分别为4%、0%以及0%。平均随访时间(26±21)个月,内脏人工血管通畅率95.3%,所有闭塞的内脏人工血管均为肾动脉,无1例引起永久性截瘫,2例患者需再干预,1例出现Ib型内漏,1例出现III型内漏,5年免于再干预率为94%,Kaplan-Meier总体生存率为1年78%、5年62%,5年主动脉相关生存率为87%。结论:这些更新后的结果 ,继续支撑着这一观点:运用完全内脏动脉去分支联合动脉瘤腔内隔绝的杂交技术治疗高龄且不适合传统开放手术的高危TAAA患者是一种理想的选择,而采取分期手术的方式能取得更佳的结果。Gchad Hughes Nicholas D Andersen Jennifer M Hanna Richard L McCann 老启芳 2015中国普通外科杂志2015,24,6:2
