结肠癌手术中使用多种方法进行重建，包括手工缝合或吻合术。然而，很少有报告比较重建方法的短期结果。本研究比较了 Delta 形吻合术 (Delta) 和功能性端对端吻合术 (FEEA) 的短期结果。我们回顾性回顾了 2016 年 1 月至 2023 年 12 月期间连续接受 FEEA 或 Delta 重建结直肠手术的 1314 例患者。根据FEEA重建（F组；n = 1242）或Delta（D组；n = 72）分为两组。应用倾向评分匹配来最大程度地减少选择偏倚的可能性并平衡可能影响术后并发症的协变​​量。比较各组近期疗效。F组发生术后并发症215例（17.3%），D组8例（11.1%）。匹配前，横结肠癌的发生率较高（p = 0.002），临床N阳性状态的发生率较低（44.1% vs 16.7%，p< 0.001），远处转移的发生率较低（11.7% vs 1.4%，p= 0.003） ），并且 D 组中腹腔镜手术更为频繁（87.8% 对比 100%，p<<0.001）。匹配后，组间任何临床因素均无明显差异。 D 组的失血量显着较低（28 mL 与 10 mL，p = 0.002），但组间手术时间和术后并发症发生率相似。Delta 和 FEEA 均被认为是安全的重建方法。需要进一步研究来阐明 Delta 和 FEEA 的适当案例选择。© 2024。Springer Nature Switzerland AG。

Several methods are used for reconstruction in colon cancer surgery, including hand-sewn or stapled anastomosis. However, few reports have compared short-term outcomes among reconstruction methods. This study compared short-term outcomes between delta-shaped anastomosis (Delta) and functional end-to-end anastomosis (FEEA).We retrospectively reviewed 1314 consecutive patients who underwent colorectal surgery with FEEA or Delta reconstruction between January 2016 and December 2023. Patients were divided into two groups according to reconstruction by FEEA (F group; n = 1242) or Delta (D group; n = 72). Propensity score matching was applied to minimize the possibility of selection bias and to balance covariates that could affect postoperative complications. Short-term outcomes were compared between groups.Postoperative complications occurred in 215 patients (17.3%) in F group and 8 patients (11.1%) in D group. Before matching, transverse colon cancer was more frequent (p = 0.002), clinical N-positive status was less frequent (44.1% versus 16.7%, p < 0.001), distant metastasis was less frequent (11.7% versus 1.4%, p = 0.003), and laparoscopic approach was more frequent (87.8% versus 100%, p < 0.001) in D group. After matching, no differences in any clinical factor were evident between groups. Blood loss was significantly lower (28 mL versus 10 mL, p = 0.002) in D group, but operation time and postoperative complication rates were similar between groups.Delta and FEEA were both considered safe as reconstruction methods. Further studies are needed to clarify appropriate case selection for Delta and FEEA.© 2024. Springer Nature Switzerland AG.
