术前内镜下自体血标记定位应用于腹腔镜结直肠肿瘤手术的临床效果分析

为评价内镜下自体血标记定位在腹腔镜结直肠肿瘤术前应用的临床价值，回顾分析2019年1月—2021年1月在同济大学附属东方医院行结肠镜下自体血定位并随后行腹腔镜手术的结直肠肿瘤患者资料30例。腹腔镜手术中根据结肠浆膜面局部红色标记判断病灶所在位置。术中探查评估染色清晰度，观察有无注射自体血泄漏情况。所有患者在结肠镜下顺利完成自体血定位，无出血、穿孔和发热等并发症。腹腔镜探查可见清晰的自体血染色部位，未见染色弥散、泄漏污染术野情况。术后病理证实标本切缘阴性。说明经结肠镜下注射自体血是一种理想的腹腔镜结直肠肿瘤手术前病灶定位方法，安全有效，值得临床推广。

Application of preoperative colonoscopic autologous blood labeling to localization for laparoscopic colorectal surgery

To evaluate the effect of preoperative colonoscopic autologous blood labeling to localization for laparoscopic colorectal surgery, data of 30 patients with colorectal neoplasms who underwent colonoscopic autologous blood localization followed by laparoscopic surgery in Shanghai East Hospital, Tongji University from January 2019 to January 2021 were retrospectively analyzed. The location of lesions was determined by local red marks on the serosal surface of the colon during laparoscopic surgery. The clarity of staining and whether there was leakage of injected autologous blood were observed. All patients successfully completed the localization of autologous blood under colonoscopy, without bleeding, perforation, fever or other complications. Laparoscopic exploration showed clear sites of autologous blood staining, without staining dispersion or leakage polluting the operation field. Postoperative pathology confirmed that the margin of the specimen was negative. The injection of autologous blood under colonoscopy is a safe and effective preoperative localization method for laparoscopic colorectal neoplasms surgery, which is worthy of clinical recommendation.
