ABSTRACT
Objective:To evaluate the efficacy and safety of continuous infusion of low-dose intravenous (Ⅳ) heparin during perioperative period of simultaneous pancreas-kidney (SPK) transplantation for donation after citizen death (DCD) donor to prevent pancreatic thrombosis post-transplantation.Methods:From January 2015 to August 2019, 46 DCD donors undergoing SPK were divided into retrospective cohort groups 1 ( n=27) and 2 ( n=19). Group 1 received aspirin enteric-coated tablets only at Day 1 post-SPK. In Group 2, 5-7 days of continuous infusion of heparin 260 IU per hour at Day 1 post-SPK was followed by a daily intake of aspirin enteric-coated tablets of 100 mg. Incidence of thrombus, recovery of graft function and adverse reactions of anticoagulant therapy were observed. Results:Thrombosis occurred in (5.3%, 1/19 vs 14.8%, 4/27) in heparin and non-heparin groups. Thrombosis and graft loss were significantly lower in heparin group than those in non-heparin group ( P<0.05). Conclusions:Continuous infusion of low-dose heparin vein is effective and safe in preventing thrombosis after SPK transplantation.
ABSTRACT
Objective To summarize the experience of one case of anastomotic leakage after simultaneous pancreas-kidney transplantation (SPK ) with enteric drainage .Methods One case of type 2 diabetes mellitus complicated with end-stage nephropathy undergoing SPK was retrospectively analyzed .Iliac venous systemic circulation was employed for pancreatic venous reflux ,transplanted pancreas exocrine via enteric drainage and side-to-side anastomosis between donor pancreaticoduodenum and recipient jejunum . Pancreatoduodenal anastomotic leakage occurred at 12 days post-operation .During re-operation ,Roux-en-Y anastomosis was established between donor pancreaticoduodenum and recipient jejunum .And the relevant domestic and foreign literatures were searched .Results The follow-up time was 3 month after a second operation .Recipient pancreas and kidney transplantation survived well . There was no onset of enteric leakage .The incidence of anastomotic leakage varies greatly between different transplantation centers both at home and abroad .The incidence ranged from 3 .6％ to 11 .3％ .And the risk of pancreatic loss was as high as 54 .6％ .Conclusions As a severe postoperative complication ,anastomotic fistula after SPK may cuase abdominal infection . Even after reparing enteric fistula , the risk of leakage remains high . Roux-en-Y anastomosis is other therapeutic option .
ABSTRACT
Objective To explore the influencing factors and treatment strategies of long-term survival after simultaneous pancreas and kidney transplantation (SPK ) .Methods One case of long-term post-SPK survival was reviewed and its influencing factors were analyzed along with the relevant literature .Results At 10 years post-SPK ,the patient lost transplanted kidney due to rejection and underwent secondary kidney transplantation . The transplanted pancreas functioned well and has survived for more than 18 years .Conclusions Strict preoperative screening ,adopting mature surgical approaches ,aggressive managements of various perioperative complications ,strengthening of health education of recipients ,improving of compliance and long-term regular follow-ups are conducive for enhancing long-term survival of recipients and grafts of SPK .
ABSTRACT
Objective To reduce the perioperative complications of simultaneous pancreas and kidney transplantation (SPK ) and boost the clinical efficacy by exploring its perioperative management in diabetics with end-stage renal disease .Methods Retrospective analysis was performed for the clinical data of 5 diabetics with end-stage renal disease undergoing SPK since 2017 .Results The cold ischemic time of all allografts was under 8 hours .No surgical complications occurred in recipients post-transplantation .Two patients were complicated with hyperkalemia and their serum potassium levels normalized after treatment .One case of bleeding in abdominal cavity was cured conservatively . Renal functions of two patients with delayed renal function post-transplantation gradually recovered after hematodialysis . One case of peritransplant fluid collection recovered after debridement and drainage .Another case of acute left heart failure and cardiac arrest at 45 days post-transplantation resumed normal heart rhythm after rescue .However ,his consciousness could not be restored and his families gave up subsequent treatments . Transplanted kidneys and pancreases of these 4 patients normalized .Follow-up was conducted until March 20 , 2019 . They became insulin and dialysis independent and serum creatinine and blood glucose normalized .Diabetic complications were relieved and their quality-of-life also improved significantly .Conclusions SPK is an effective treatment for diabetics with end-stage renal disease .While maintaining normal serum creatinine and blood glucose , it may liberate patients from insulin dosing and dialytic maintenance ,lower diabetic complications and improve quality-of-life .
ABSTRACT
Objective To preliminarily explore the clinical efficacy of ipsilateral simultaneous pancreas and kidney transplantation (SPK) .Methods Ipsilateral SPK was performed in 40 patients from September 2016 to August 2018 .During a follow-up period of 6 to 29 months ,we summarized the efficacy and complications of the technique .Results Up to now ,38 patients achieved an exceelent clinical efficacy with no major surgical complications .However ,two patients died of severe pneumonia .The postoperative serum levels of creatinine at 3 ,6 ,12 ,24 months were 107 ,102 ,107 ,110 umol/L ;creatinine clearance rate 64 ,67 ,64 ,63 ml/min;fasting glucose 4 .6 ,5 .1 ,4 .6 ,5 .2 mmol/L ;glycated hemoglobin 4 .8％ , 5 .4％ ,4 .9％ ,5 .2％ respectively .And 1/2-year pancrea and kidney graft survival rates both were 92％ . Complications included kidney graft rejection (n= 11) ,pancreas graft rejection (n= 12) ,simultaneous renal & pancreas graft rejection (n=6) ,renal graft DGF (n=1) ,pulmonary infection (n=14) ,urinary tract infections (n=18) ,gastrointestinal bleeding (n=10) diarrhea (n=6) ,splenic venous thrombosis (n=2) ,incomplete ureteric obstruction of renal allograft (n=3) ,urine leakage (n=1) and pancreas allograft dysfunction (n= 2) .There were no severe surgical complications .After aggressive interventions ,all postoperative complications were cured and none required excision of kidney or pancreas .Conclusions Ipsilateral SPK has definite therapeutic efficacy and it is worth wider popularization .
ABSTRACT
ObjectiveTo summarize the clinical experience of simultaneous pancreas and kidney transplantation (SPK) after liver transplantation for patients with diabetes and uremia.MethodsThe clinical data of two patients who received SPK after liver transplantation were retrospectively analyzed.The two male patients had type 2 diabetes mellitus before liver transplantation,and suffered from endstage uremia due to diabetic nephropathy and immunosuppressant-induced toxicity.Rapid technique for combined abdominal multiple viscera procurement was performed.Kidneys,pancreas,duodenum segment and spleen were procured.Renal allograft was placed in the left iliac fossa,whereas pancreas allograft in the right iliac fossa. The pancreatic allograft exocrine secretion was drained into the proximal jejunum via a side-to-side duodenojujunostomy. Quadruple immunosuppressive regime including IL2 receptor monoclonal antibody induction,tacrolimus (Tac),mycophenolate mofetil (MMF) and steroid were used in case 1,and ATG and methylprednisolone were used in case 2.ResultsSPK was successfully applied to these two patients without serious surgical complications such as pancreatitis,graft and pancreatic fistula. The immunosuppressive regimen was based on tacrolimus with ATG induction,MMF and steroids.In the second case,serum creatinine level was decreased to the normal range within 1 week after the operation and then elevated continuously even he received empirical anti rejection treatment,Tac was tampered and rapamycin was used when the renal graft biopsy indicated drug toxicity,and creatinine level was decreased 3 weeks after the operation and recovered to the normal range at 5th week post-transplant. Both of the two patients achieved euglycemia with insulin independence about 10 days after the operation.And now these two patients have been followed up for 36 and 9 months,and the grafts function of the liver,kidney and pancreas was normal. Conclusion Immunologic reaction in patients undergoing simultaneous pancreas and kidneytransplantationafterlivertransplantationseemsmorecomplex, andareasonable immunosuppressive regimen is important to improVe the outcome.
