Colorectal carcinoma (CRC) is a very common cancer found worldwide. When metastasizing, it would often seed the liver via traveling through the portal circulation; however, locoregional metastasis is also possible. Abdominal wall seeding postoperatively has been described to happen rarely in those who underwent definitive surgery for CRC. Currently, five case reports are in publication describing this phenomenon. Here, we present a case of a drain site abdominal wall tumor recurrence after definitive surgery with curative intent of a sigmoid adenocarcinoma. Those with higher tumor-node-metastasis (TNM) staging and a primary site at the sigmoid colon were found to be at a higher risk for recurrence. Despite this, abdominal wall recurrence of CRC is exceptionally rare, with less than 1% of those with locoregional recurrence presenting at the incision site or trocar site placement. Because of the rarity of this complication, few studies are available that detail the management of abdominal wall recurrence of CRC. Further studies on this subject are currently warranted.
结直肠癌（CRC）是一种在全球范围内都非常常见的癌症。发生转移时，它常常通过门静脉循环转移至肝脏；不过，局部区域转移也是有可能的。据描述，接受结直肠癌根治性手术的患者术后腹壁种植极为罕见。目前有五例病例报告发表描述了这一现象。在此，我们报告一例乙状结肠腺癌根治性手术后引流部位腹壁肿瘤复发的病例。发现肿瘤-淋巴结-转移（TNM）分期较高且原发部位在乙状结肠的患者复发风险更高。尽管如此，结直肠癌腹壁复发极为罕见，局部区域复发的患者中不到1%在切口部位或套管针穿刺部位出现复发。由于这种并发症很罕见，很少有研究详细阐述结直肠癌腹壁复发的处理方法。目前有必要对该主题进行进一步研究。
