Suture ligation for submucosal hemostasis during hand-sewn side-to-side duodeno-ileostomy in simultaneous pancreas and kidney transplantation.

BACKGROUND: Enteric anastomotic (EA) bleeding is a potentially life-threatening surgical complication associated with enteric anastomosis during simultaneous pancreas and kidney transplantation (SPKT). AIM: To investigate whether suture ligation (SL) for submucosal hemostasis during hand-sewn enteric anastomosis could decrease the morbidity of early EA bleeding in SPKT. METHODS: We compared the outcomes of 134 patients classified into SL (n = 44) and no SL (NSL) groups (n = 90). This study adheres to the declarations of Istanbul and Helsinki and all donors were neither paid nor coerced. RESULTS: During the first postoperative week, the EA bleeding rate in the SL group was lower than that in the NSL group (2.27% vs 15.56%; P = 0.021); no relationship was found between EA bleeding and donor age, mean pancreatic cold ischemia time, platelet count, prothrombin time international normalized rate, activated partial thromboplastin time, and thrombin time. Anastomotic leakage was observed in one case in the SL group at postoperative day (POD) 14 and in one case at POD 16 in the NSL group (P = 0.754). No significant difference was found between the two groups in the patient survival, pancreas graft survival, or kidney graft survival. CONCLUSION: SL for submucosal hemostasis during hand-sewn enteric anastomosis in SPKT can decrease the morbidity of early EA bleeding without increasing the anastomotic leakage rate.

[The effect of the different immunosuppression therapy on CD4(+)Foxp3(+) Treg cells in kidney recipients].

OBJECTIVE: To investigate the effect of the different immunosuppression therapy on CD4(+)Foxp3(+)regulatory T cells (CD4(+)Foxp3(+)Treg cells) in the peripheral blood monocytes of kidney transplantation recipients. METHODS: A Closed Cohort study was conducted in 50 primary living kidney transplant recipients between January 2006 and January 2008, who had been followed up for 1 year. The recipients divided into calcineurin inhibitors group (CNI + MMF + Pred) (19 recipients, including cyclosporin group 10 recipients and tacrolimus group 9 recipients), rapamycin group (RAPA + MMF + Pred) (31 recipients). Twenty end-stage renal disease patients were in control group. The frequency of CD4(+)Foxp3(+)Treg cells in total CD4(+)T cells was analyzed by flow cytometry in peripheral blood from three groups, results were compared. RESULTS: The clinical variables of recipients such as age, sex, cold ischemia time, human leucocyte antigen mismatch, panel reaction antibody, rejection episode were no significant difference. The percentage of CD4(+)Foxp3(+)Treg cells in total CD4(+) cells was significantly higher in rapamycin group and end-stage renal disease group than calcineurin inhibitors group (P < 0.01). The level of CD4(+)Foxp3(+)Treg cells between cyclosporin group and tacrolimus group was no significant difference (P > 0.05). CONCLUSION: The level of CD4(+)Foxp3(+)Treg was significantly higher in patients receiving RAPA + MMF + Pred than the patients receiving CNI + MMF + Pred, which suggested that RAPA may be play a more important role in immune tolerance induction.
