Abstract

BACKGROUND

The optimal lymph node dissection with central vascular ligation is an important part for oncological outcomes after laparoscopic right-sided colon cancer surgery. Few studies have examined the clinical value of indocyanine green fluorescence imaging-guided D3 dissection for right-sided colon cancer.

OBJECTIVES

We assessed the clinical value of indocyanine green fluorescence imaging-guided laparoscopic surgery in improving the radicality of lymph node dissection for right-sided colon cancer by comparing the outcomes of conventional laparoscopic surgery.

DESIGN

The data were retrospectively reviewed and analyzed.

SETTING

This study was conducted at a single university hospital.

PATIENTS

A 1:2 matched case-control study included 25 patients undergoing fluorescence imaging-guided laparoscopic surgery and 50 patients undergoing conventional laparoscopic surgery for clinical T3 or T4 right-sided colon cancer between June 2016 and December 2017.

MAIN OUTCOME MEASURES

The extent of D3 dissection and pathological results (tumor stage, lymph node yield, and number of metastatic lymph nodes) were analyzed.

RESULTS

The 2 groups were similar in baseline characteristics. The numbers of harvested pericolic and intermediate lymph nodes were not different between the 2 groups. The numbers of central lymph nodes (14 vs 7, p < 0.001) and total harvested lymph nodes (39 vs 30, p = 0.003) were significantly higher in the fluorescence group than in the conventional group. In the multivariate analysis, the use of indocyanine green fluorescence imaging was an independently related factor for the retrieval of higher numbers of overall and central lymph nodes. The number of metastatic lymph nodes was not significantly different between the 2 groups.

LIMITATIONS

The results of this study were limited by its small patient numbers and retrospective nature.

CONCLUSIONS

Real-time indocyanine green fluorescence imaging of lymph nodes may improve the performance of more radical D3 lymph node dissection during laparoscopic right hemicolectomy for advanced right-sided colon cancer.

El número de ganglios linfáticos pericólicos e intermedios recolectados no fue diferente entre los dos grupos. El número de ganglios linfáticos centrales (14 vs 7, p < 0.001) y el total de ganglios linfáticos recolectados (39 vs 30, p = 0.003) fueron significativamente mayores en el grupo de fluorescencia que en el grupo convencional. En el análisis multivariante, el uso de imágenes de fluorescencia verde indocianina fue un factor independiente relacionado para la recuperación de un mayor número de ganglios linfáticos centrales y globales. El número de ganglios linfáticos metastásicos no fue significativamente diferente entre los dos grupos.Los resultados de este estudio fueron limitados por su pequeño número de pacientes y su naturaleza retrospectiva.Las imágenes de fluorescencia verde indocianina en tiempo real de los ganglios linfáticos pueden mejorar el rendimiento de la disección más radical de los ganglios linfáticos D3 durante la hemicolectomía derecha laparoscópica para el cáncer de colon avanzado del lado derecho.

摘要

背景

腹腔镜右半结肠癌手术中,优化的淋巴结清扫术伴中央血管结扎是肿瘤学结果的重要组成部分。少数研究检查了吲哚菁绿荧光成像引导 D3 解剖术对右半结肠癌的临床价值。

目的

我们通过比较常规腹腔镜手术的结果,评估吲哚菁绿荧光成像引导腹腔镜手术在提高右半结肠癌淋巴结清扫根治性方面的临床价值。

设计

数据回顾性分析。

地点

这项研究在一家大学医院进行。

患者

2016 年 6 月至 2017 年 12 月,对 25 例接受荧光成像引导腹腔镜手术和 50 例接受常规腹腔镜手术的临床 T3 或 T4 右半结肠癌患者进行了 1:2 匹配病例对照研究。

主要观察指标

分析 D3 解剖的范围和病理结果(肿瘤分期、淋巴结检出数和转移淋巴结数)。

结果

两组基线特征相似。两组间结肠旁和中间淋巴结的检出数无差异。中央淋巴结的检出数(14 枚比 7 枚,p < 0.001)和总淋巴结检出数(39 枚比 30 枚,p = 0.003)均显著高于对照组。多变量分析显示,吲哚菁绿荧光成像的使用是提高总淋巴结和中央淋巴结检出量的独立相关因素。两组间转移淋巴结的数量无显著差异。

局限性

本研究结果受到患者数量少和回顾性的限制。

结论

在腹腔镜右半结肠切除术治疗晚期右半结肠癌时,实时吲哚菁绿荧光成像引导下的淋巴结成像可能有助于实现更彻底的 D3 淋巴结清扫。详见视频摘要,网址:http://links.lww.com/DCR/B150。
