膀胱引流式胰肾联合移植术后严重代谢性酸中毒的外科治疗

目的探讨膀胱引流式胰肾联合移植长期存活受者代谢性酸中毒的治疗方法。方法1例女性45岁糖尿病肾病、尿毒症患者膀胱引流式胰肾联合移植术后3年并发严重代谢性酸中毒，二次手术改为同肠引流。绕移植胰腺十二指肠膀胱吻合口切除已游离的带膀胱擘吻合口，于距同盲部40cm处回肠与移植胰腺十二指肠段行侧侧吻合，吻合口长约5cm，距吻合口15cm处冉行回肠襻侧侧吻合。结果患者术后恢复好。服用常规免疫抑制剂，住院30d。随访4年，患者血气分析正常。肾功能、血糖波动在正常范围。结论膀胱引流式胰肾联合移植术后严重代谢性酸中毒患者改用回肠引流是一种有效、安全的治疗方法。

Conversion from bladder to ileal drainage for the treatment of metabolic acidosis following simultaneous pancreas and kidney transplantation (a case report)

Objective To investigate the therapeutic method of metabolic acidosis in long-term sur- vival patients undergoing simultaneous pancreas and kidney transplantation.Methods A 45-year-old fe- male patient,who had undergone simultaneous pancreas and kidney transplantation(due to diabetic ne- phropathy and uremia)with bladder drainage 2 years before,developed severe metabolic acidosis,and thus underwent surgical conversion from bladder to ileal drainage.The procedure was as follows.The stoma of duo- denocystostomy was isolated and resected.The site of cystostomy was closed in two layers.The graft duode- num was then anastomosed to a loop of the recipient's ileum,which was proximal 40 cm from the ileocecum in a side-to-side manner.Results The metabolic acidosis resolved postoperatively.The patient received conventional immunosuppressants.The hospital stay was 30d.Follow-up of 4 years showed normal pancreas and kidney functions.Conclusions Conversion from bladder to ileal drainage is safe and effective for metabolic acidosis related to the exocrine secretions of bladder drained pancreas graft in simultaneous pancre- as and kidney transplant recipients.
