胃次全切除后残胃-十二指肠-连续性空肠间置术的临床研究

目的探讨胃次全切除后残胃、十二指肠、连续性空肠间置术的临床疗效。方法将远端胃癌患者54例,分为两组,A组(26例)胃次全切除后应用手工缝合或管状消化道吻合器行残胃与空肠、十二指肠与空肠的端侧吻合,再行空肠侧侧吻合,将胃空肠吻合口的近端空肠和十二指肠空肠吻合口的远端空肠分别结扎阻断,以形成连续的间置空肠;B组(28例)胃次全切除后行BillrothⅡ式消化道重建;统计两组患者消化道重建的时间,术后3个月和6个月的体重、预后营养指数(PNI)、Visick分级指数。结果两组患者术后均顺利恢复,未发生吻合口漏或梗阻等术后并发症;A、B组平均消化道重建时间分别为53min±9min和57min±6min(t=-2.145,P=0.037);术后6个月时A组体重和PNI均恢复到手术前水平,而B组虽有所恢复,但与术前相比差异仍有统计学意义。术后6个月Visick分级指数A组明显优于B组(u=2.1,P<0.05)。结论残胃、十二指肠、连续空肠间置术能够使食物通过十二指肠,恢复生理通道,并降低胃次全切除术时消化道重建的难度,避免胆汁反流,改善生活质量。

Residual stomach, duodenum, and continual jejunal interposition after subtotal gastrectomy

OBJECTIVE: To investigate the clinical effect of residual stomach, duodenum, and continual jejunal interposition on the patients of gastric cancer after subtotal gastrectomy. METHODS: Fifty-four patients with gastric cancer after subtotal gastrectomy were randomly divided into 2 groups: Group A (n = 26, receiving digestive tract reconstruction by manual end-to-side anastomosis of residual stomach and jejunum, end-to-side anastomosis of residual duodenum and jejunum, and side-to-side anastomosis of jejunum and jejunum, then the jejunum proximal to the stomach-jejunum anastomosis and the jejunum distal to the duodenum-jejunum anastomosis were ligated so as to form an integral continual jejunal interposition; and Group B (n = 28, receiving Bilroth digestive tract reconstruction. The operation time, body weight, prognosis nutrition index (PNI), and Visick score 3 and 6 months after the operation were observed. RESULTS: All patients recovered quickly and no complicating anastomosis leakage and obstruction was found. It took 53 +/- 9 minutes to finish the reconstruction in Group A, significantly shorter than that in Group B (57 +/- 6 minutes, t = -2.145, P = 0.037). The body weight and PNI of both groups decreased significantly 3 months after the operation in comparison with those before the operation (both P < 0.05). The body weight and PNI of Group A returned to the levels before operation. Although the body weight and PNI of Group B recovered to some extent 6 months after operation, they remained significantly lower than those before operation both P < 0.05). The Visick score 6 months after operation of Group A was superior to that of Group B (t = 2.1 P < 0.05). CONCLUSION: Residual stomach, duodenum, and continual jejunal interposition after subtotal gastrectomy helps overcome the difficulty in the procedure of digestive tract reconstruction and restore the physiological passage through duodenum, thus avoiding reflux and improving patients' quality of life.
