利用弯曲端端吻合器（ＰＣＥＥＡ）行胃肠道吻合术在很多国家已较广泛地应用于临床，它对减少术后吻合口痊等并发症，以及使更多的低位直肠癌患者避免腹部结肠造口提供了帮助。作者自１９９４年３月起，对２０例直肠癌患者利用ＰＣＥＥＡ行直肠癌前切除吻合术。与对照组进行比较，表明此法可明显降低吻合口瘘发生率，缩短手术时间，减少术后平均住院时间。并复习有关文献对临床使用体会和并发症预防进行初步探讨。 Gastrointestinal anastomosis using curved end-to-side anastomosis (PCEEA) has been more widely used in many countries. It reduces postoperative complications such as anastomotic leakage, and prevents more patients with low rectal cancer from avoiding abdominal colon. Stoma provides help. Since March 1994, the author has performed rectal cancer anastomosis with PCEEA in 20 patients with rectal cancer. Comparison with the control group showed that this method can significantly reduce the incidence of anastomotic leakage, shorten the operation time, and reduce the average hospital stay after surgery. Review the relevant literature on the clinical use experience and prevent complications.
