保留空肠黏膜与胰肠直接套入在胰肠吻合术的临床研究

目的 对胰肠直接套入和包盖于残胰腺的空肠端不去黏膜化处理的胰肠吻合方式进行探讨.方法 对2005年3月至2009年8月期间行胰腺切除手术的28例病例进行临床分析,其中行胰十二指肠切除术26例,行保留胰头的胰腺切除术2例.术中均采用残胰直接套入空肠吻合方法,即包盖于残胰端的空肠不去黏膜化处理,将残胰直接套入空肠2.0 cm～2.5 cm,将空肠断端与残胰胰腺相应部位间断缝合固定,距离残胰断端1 cm处用7号丝线环绕空肠将残胰予以捆扎.结果 28例患者均未发生胰瘘,1例患者术后因残胰断端出血行二次手术,全部病例术后均顺利恢复出院.结论 复杂的胰肠吻合尤其是通过缝合方式除增加手术时间外,更未必能减少甚至增加胰瘘的发生.而采用残胰直接套入空肠与包盖于残胰端的空肠端不去黏膜化处理的胰肠吻合方法,除吻合方法更为简单外,更重要的是保持了包盖于残胰腺的空肠壁完整性,在捆扎线的捆扎作用下可降低或避免胰瘘的发生.

The clinical study of jejunal mucus preserving plus end to end pancreaticoenterostomy

Objective To investigate the pancreaticoenterostomy technique using end to end anastomosis of remianing pancreas and jejunum with jejunum mucus preserved. Methods 28 cases underwent pancreatectomy were observed and analyzed from May 2005 to August 2009. There were 26 cases underwent duodenopancreatectomy and 2 cases underwent the pancreatectomy of pancreas body and tail. All cases used the end to end pancreaticoenterostomy, remnant pancreas was directly anastomosed with jejunum without destroy of jejunal mucosa. During the operation, 2.0 cm～2.5 cm long remnant of pancreas was pulled into jejunum without mucosa destroyed. Then, the cut end of the jejunum was fixed on the pancreatic remnant correspondingly by interrupted suture. Finally, a 7-silk suture was used to bind the jejunum and the pancreatic remnant together 1 cm away from the cut surface of the pancreatic remnant. Results 1 case underwent operated again due to bleeding of the pancreatic remnant. 28 patients recovered and discharged from hospital without having the complication of pancreatic fistula. Conclusions Because of the complicated suturation methods, the conventional pancreaticoenterostomy consumes more time. But it still has rather high incidence of pancreatic fistula.The new pancreaticoenterostomy which we used can shorten the operating time and integrity and binding stomas. It is effective to lower the incidence of pancreatic fistula.
