Abstract

BACKGROUND

The examination of the efficacy of near-infrared imaging using indocyanine green in laparoscopic lateral pelvic lymph node dissection remains insufficient.

OBJECTIVE

The aim of this study was to examine whether near-infrared imaging contributed to an increase in the total number of harvested lateral pelvic lymph nodes in laparoscopic lateral pelvic lymph node dissection.

DESIGN

This was a retrospective, multi-institutional study with propensity score matching.

SETTINGS

We conducted this study within the framework of the Yokohama Clinical Oncology Group in Japan.

PATIENTS

The study population included consecutive patients with middle-low rectal cancer (clinical stage II to III) who underwent laparoscopic lateral pelvic lymph node dissection between January 2013 and February 2018.

MAIN OUTCOME MEASURES

The total number of harvested lateral pelvic lymph nodes was compared in laparoscopic lateral pelvic lymph node dissection with and without near-infrared imaging.

RESULTS

A total of 172 eligible patients were included; 84 of these patients underwent laparoscopic surgery with near-infrared imaging. After propensity score matching, 58 patients were matched in each of the near-infrared and the non-near-infrared groups. The operation time in the near-infrared group was significantly longer than that in the non-near-infrared group (426 vs 369 min), and the amount of intraoperative blood loss in the near-infrared group was significantly smaller than that in the non-near-infrared group (13 vs 110 mL). The total number of harvested lateral pelvic lymph nodes in the near-infrared group was significantly higher than that in the non-near-infrared group (14 vs 9). There were no significant differences in the postoperative complication rates of the 2 groups.

LIMITATIONS

The limitations of the present study include its retrospective design.

CONCLUSIONS

This study revealed that laparoscopic lateral pelvic lymph node dissection combined with near-infrared imaging could increase the total number of harvested lateral pelvic lymph nodes without impairing functional preservation.

摘要

背景

使用吲哚菁绿的近红外成像在腹腔镜侧盆淋巴结清扫术中的疗效仍不充分。

目的

本研究旨在检查近红外成像是否有助于增加腹腔镜侧盆淋巴结清扫术中侧盆淋巴结的总检出数。

设计

这是一项回顾性、多机构研究,采用倾向评分匹配。

设置

我们在日本横浜临床肿瘤组的框架内进行了这项研究。

患者

研究人群包括连续接受腹腔镜侧盆淋巴结清扫术的中低位直肠癌(临床分期 II 至 III 期)患者。

主要观察指标

比较腹腔镜侧盆淋巴结清扫术联合和不联合近红外成像时侧盆淋巴结的总检出数。

结果

共纳入 172 例符合条件的患者;其中 84 例接受了近红外成像腹腔镜手术。经倾向评分匹配后,近红外组和非近红外组各匹配 58 例。近红外组的手术时间明显长于非近红外组(426 比 369 分钟),术中出血量明显少于非近红外组(13 比 110 毫升)。近红外组的侧盆淋巴结总检出数明显多于非近红外组(14 比 9)。两组术后并发症发生率无显著差异。

局限性

本研究的局限性包括其回顾性设计。

结论

本研究表明,腹腔镜侧盆淋巴结清扫术联合近红外成像可在不损害功能保留的情况下增加侧盆淋巴结的总检出数。请观看视频摘要,网址:http://links.lww.com/DCR/B800。(由 Dr. Xavier Delgadillo 翻译)本研究在日本临床试验注册中心注册,注册号为 UMIN000041372(http://www.umin.ac.jp/ctr/index.htm)。
