[Clinical effect analysis of 146 cases of ipsilateral simultaneous pancreas and kidney transplantation].

Objective: To investigate the clinical effect of ipsilateral simultaneous pancreas and kidney transplantation (SPK). Methods: A total of 146 cases of SPK surgeries completed in the Second Affiliated Hospital of Guangzhou Medical University from September 2016 to June 2020 were selected to summarize the outcome, curative effect and complications of the operation. Results: The patients were followed up for 1 to 45 months. Good clinical results were obtained in 146 patients. Renal function indicators suggest that on the 7th day after operation, the serum creatinine returned to normal level [142.4 (108.6, 213.4)µmol/L]. The index of pancreatic function decreased to the normal level as expected. The level of blood amylase was 160.5(109.3, 249.8) U/L within 7 days after operation, and then decreased. The trend of urinary amylase was similar to that of blood amylase, which was 240(121.0, 370.0) U/L 7 days after operation, and glycosylated hemoglobin decreased to the normal level (5.8%±1.4%) 1 month after operation. The main medical complications were infection including pulmonary infection (26.03%, 38/146), urinary tract infection (26.03%,38/146), and abdominal infection (4.79%,7/146), acute rejection including renal graft rejection (5.8%,8/146), pancreas/duodenum rejection (18.49%,27/146), and renal graft combined pancreatic graft rejeciton (6.85%,10/146), as well as gastrointestinal bleeding (30.82%,45/146), of which 5 cases were severe bleeding (3.42%, 5/146). The main surgical complications were poor incision healing (10.27%, 15/146), serious surgical complications including arteriovenous thrombosis of the transplanted pancreas (2.05%, 3/146) and intestinal leakage (0.68%,1/146). The 1-year and 3-year patient, renal and pancreatic survival rates were both 92.5%, 91.5% and 89.5%, respectively, and despite the death, the 1-year, 3-year transplanted kidney survival rate was both 99.3%, and 95% for the the 1-year, 3-year pancreas survival rate. Conclusion: Strict preoperative evaluation of the function of large organs, reasonable surgical methods, perioperative anticoagulation, and prompt diagnosis of complications can achieve good clinical results for patients with SPK.
