非离断式Roux—en—Y吻合在远端胃癌根治术后消化道重建中的应用

目的评价非离断式Roux-en-Y吻合用于远端胃癌根治术后消化道重建的临床效果。方法回顾性分析2005年3月至2008年3月间天津医科大学肿瘤医院行远端胃癌根治术且有完整随访资料的419例患者．根据其不同的消化道重建方式分为：UncutRY组（非离断式Roux-en-Y吻合）127例,BI组（BillrothI式）138例,M—BⅡ组（改良BillrothII式）108例,RY组（Roux—en-Y吻合）46例。结果UncutRY组患者手术时间[（132．6±19．2）min]和术后住院时间[（10．4±1．2）d]较RY组[（142．5±11．7）min和（12．1±3．7）d]缩短（P〈0．05）;术后反流性胃炎发生率（3．2％,4／127）较BI组（24．6％,34／138,P〈0．05）和M．BII组（25．9％,28／108,P〈0．05）下降;吻合口溃疡发生率（0／127）较M—BⅡ组（4．6％,5／108,P〈0．05）下降;Roux-en-Y潴留综合征（RSS）发生率（0／127）较RY组（17．4％,8／46,P〈0．05）下降。结论非离断式Roux．en．Y在保留传统Roux—en—Y术式减少碱性反流优点的同时．克服了RSS的弊病,是胃大部切除术后理想的消化道重建术式。

Use of uncut Roux-en-Y reconstruction after distal gastrectomy for gastric cancer

Objective To evaluate the clinical efficacy of uncut Roux-en-Y reconstruction after distal gastrectomy for gastric cancer. Methods Clinical data of 419 patients who underwent distal gastrectomy for gastric cancer with complete follow-up data between March 2005 and March 2008 in the Cancer Institute and Hospital of Tianjin Medical University. Patients were divided into B I (138 cases with Billroth I reconstruction), M-B II (108 cases with modified Billroth II reconstruction), RY(46 cases with Roux-en-Y reconstruction) and Uncut RY(127 cases with uncut Roux-en-Y reconstruction) according to reconstructive methods. Results Patients in the Uncut RY group had a larger tumor diameter, more T3, and poorer stage of disease compared to those in the B I (P<0.05). In Uncut RY group, the operative time and postoperative hospital stay were (132.6±9.2) minutes and (10.4±1.2) days respectively,shorter than those in RY group (142.5±1.7) minutes and (12.1±3.7) days (both P<0.05), alkaline reflex gastritis rate was 3.2%, lower than that in B I group (24.6%, P<0.05) and M-B II group (25.9%,P<0.05). Marginal ulcer rate in uncut RY group was lower compared to M-B II group (P=0.019), and incidence of Roux-en-Y stasis syndrome was less compared to RY group (P=0.000). Conclusions The uncut Roux-en-Y reconstruction is both feasible and safe. It can prevent alkaline reflex gastritis and Roux-en-Y stasis syndrome. It may be the preferred technique for reconstruction after distal gastrectomy.
