【摘要】 目的 评价改良Sigma直肠膀胱术式可控性尿流改道的临床疗效。方法 在2002年1月~2004年6月对5例膀胱癌患者采用改良Sigma直肠膀胱术式。折叠乙状结肠约25cm后全层切开,再缝合成低压袋,顶端固定在骶岬处,两输尿管末端合并,从低压袋上方引入,与切除了一小片段的肠黏膜匙形吻合再植。结果 全组所有患者尿控率100%,无尿失禁、未发生明显酸碱平衡紊乱、肾功能损害及上尿路感染、上尿路结石、吻合口狭窄等并发症。结论 改良Sigma直肠膀胱术并发症低、尿控效果好,术后生活质量较高,是一种快速、安全并简单易行的尿流改道方法。

【Abstract】 Objective To introduce a modified technique of Sigma rectum pouch procedure as a continent urine reservoir after radical cystectomy.Methods 5 cases of bladder cancer underwent the modified Sigma rectum pouch operation from Jan.2001 to Jun.2004.A segment of sigmoid colon was folded and a longitudinal incision about 25cm was made on the sigmoid wall and the incision was sutured so as to form a low pressure pouch.The vertex of the new pouch was fixed to the sacrum.The ends of the 2 ureterers were anastomosed together and was then drawn into the top of the pouch for 2 cm and finally the ureterosigmoidostomy was accomplished.Results Continence rate was 100%.All the patients were able to distinguish between stool and urine.Symptomatic renal infection and hyperchloremic acidosis occurred seldomly.No patient developed upper tract stone or ureterointestinal anastomotic stricture.Conclusion The modified sigma rectum pouch procedure is a quick,safe and easy to perform urinary diversion which serves as a satisfying alternative for patients in terms of quality of life.Follow-up shows a low complication rate with good results in terms of continence.
【Key words】 bladder neoplasms; Sigma rectum pouch; continent uinary diversion
1993年Fisch等[1]首次采用Sigma直肠膀胱术做可控性尿流改道,国内程双管等[2]于2001年提出改良Sigma直肠膀胱术,我们将程双管等的方法再改良,自2002年1月~2004年6月对5例膀胱癌患者行膀胱全切除、改良Sigma直肠膀胱术,效果满意。现将结果报告如下。
1 资料与方法
1.1 一般资料 本组5例中,男3例,女2例;年龄40~67岁,平均年龄58.8岁。均为多发性、复发性膀胱癌,术前均常规检查肛门括约肌功能正常。
1.2 手术方法 术前3天进食流质并口服抗生素预防感染,术晨洗肠散溶液清洁肠道。所有患者均采用同一手术方法。全膀胱切除后,折叠乙状结肠约25cm,但不离断,先将浆肌层缝合,然后全层切开肠壁并缝合成低压袋。低压袋的顶端固定在骶岬处,两输尿管末端由后腹膜引至骶岬处穿出,输尿管一定要充分松解,以免再植后发生扭曲。两输尿管末段各纵行劈开1.5cm长后合并(相邻的两边作边边吻合),从"膀胱"低压袋的顶端开口无张力引入,突出于袋中长约2cm,切除拟行输尿管植入处1.5cm×1.5cm大小的肠黏膜片,两输尿管相对的两边及末端与肠黏膜直接作匙形吻合。两输尿管内分别留置单J管引流,连同放置在低压袋内的减压肛管一起由肛门引出并缝合固定。"膀胱"放置在腹腔内,而不必特意将其腹膜外置。术后口服少渣营养液8~10天,术后12天拔除单J管和肛管。
2 结果
5例患者术后随访双肾功能均保持正常,尿控良好,术后均常规服用小苏打片并定期接受随访,5例患者均未发生明显酸碱代谢紊乱。2个月后,大便成形,尿粪分流,夜尿仅为2~3次。所有患者平均随访23.6个月(12~41个月)均未发现上尿路感染、上尿路结石、吻合口狭窄等并发症。而尿控率100%,6个月后静脉尿路造影(见图1)均未见异常。
