目的

本研究的目的是评估术前使用印度墨水 (ETI) 进行内窥镜纹身对 I 期右侧结肠癌 (RCC) 腹腔镜手术中切除的淋巴结 (LN) 数量的影响。

方法

这项单中心回顾性研究纳入了 2010 年 1 月至 2021 年 12 月期间接受腹腔镜手术的 I 期 RCC 患者。比较了接受和未接受 ETI 治疗的患者的临床病理学背景和取回的淋巴结数量。使用多元线性回归分析来检查自变量对 LN 产量的影响。

结果

共有 169 名患者入组。其中，89 名患者 (52.7%) 被归类为 ETI 组，80 名 (47.3%) 患者被归类为非 ETI 组。两组之间在年龄、性别、体重指数或肿瘤进展方面没有显着差异。单变量分析表明，女性取回的淋巴结数量明显较多（26 对 24，p = 0.026），肿瘤位于升结肠或横结肠（盲肠 20 例，升结肠 26 例，直肠 27 例）横结肠，p < 0.001）和术前 ETI（28 对 21，p < 0.001）。在多变量线性回归分析中，女性 ( p = 0.0011)、D3 淋巴结切除术 ( p = 0.046) 和术前 ETI (p = 0.012) 与 LN 产量独立相关。

结论

在 I 期 RCC 的腹腔镜手术中，术前 ETI 增加了取回的淋巴结数量并允许进行适当的分期。

The effect of preoperative endoscopic tattooing using India ink on lymph node yield in laparoscopic colectomy for stage I right-sided colon cancer

Purpose

The purpose of this study is to evaluate the effect of preoperative endoscopic tattooing using India ink (ETI) on the number of retrieved lymph nodes (LNs) dissected during laparoscopic surgery for stage I right-sided colon cancer (RCC).

Methods

This single-center, retrospective study included stage I RCC patients who underwent laparoscopic surgery between January 2010 and December 2021. The clinicopathological background and number of LNs retrieved were compared between patients managed with and without ETI. A multiple linear regression analysis was used to examine the effect of independent variables on the LN yield.

Results

A total of 169 patients were enrolled. Of these, 89 patients (52.7%) were classified into the ETI group, and 80 (47.3%) were classified into the no-ETI group. There were no significant differences in age, sex, body mass index, or tumor progression between the two groups. A univariate analysis showed that the number of LNs retrieved was significantly higher in female (26 vs. 24, p = 0.026), with tumor localization in the ascending or transverse colon (20 in the cecum, 26 in the ascending colon, 27 in the transverse colon, p < 0.001), and with preoperative ETI (28 vs. 21, p < 0.001). In a multivariate linear regression analysis, female sex (p = 0.0011), D3 lymphadenectomy (p = 0.046), and preoperative ETI (p = 0.012) were independently associated with the LN yield.
