BACKGROUND
Sentinel lymph node (SN) mapping by dye injection on conventional laparoscopy (CL) is often precluded by the presence of mesenteric adipose tissue in patients with colorectal cancer. SN mapping on CL was compared with that on infrared ray laparoscopy (IRL) during laparoscopy-assisted colectomy (LAC).
PATIENTS AND METHODS
Forty-eight patients with colorectal cancer who underwent LAC were enrolled. The tumor was identified by intra-operative fluoroscopy with marking clips. The tumor was stained intra-operatively by peritumoral injection of indocyanine green dye. SNs were observed by CL and by IRL.
RESULTS
In all 48 patients, dye injection and tumor localization during LAC were successful. The identification of SNs on IRL was approximately five times better than that on CL. There were no false-negative cases in T1 and T2 disease by IRL.
CONCLUSION
SN mapping on IRL is superior to that on CL. SN mapping by IRL might be feasible for T1 and T2 tumors.
背景
在传统腹腔镜检查（CL）中，通过染料注射进行前哨淋巴结（SN）定位常因结直肠癌患者存在肠系膜脂肪组织而受到阻碍。在腹腔镜辅助结肠切除术（LAC）期间，将CL上的SN定位与红外线腹腔镜检查（IRL）上的SN定位进行了比较。
患者与方法
纳入48例行LAC的结直肠癌患者。术中通过荧光透视用标记夹识别肿瘤。术中通过在肿瘤周围注射吲哚菁绿染料对肿瘤进行染色。通过CL和IRL观察SN。
结果
在所有48例患者中，LAC期间染料注射和肿瘤定位均成功。IRL上SN的识别率约为CL上的5倍。IRL对T1和T2期疾病无假阴性病例。
结论
IRL上的SN定位优于CL。IRL进行SN定位对T1和T2期肿瘤可能可行。
