Objective: Many Chinese doctors have performed microinvasive esophageal cancer resection in the semi-prone position. However, few reports have focused on high-quality methods of scavenging the peripheral lymph nodes (PLNs) of the left recurrent laryngeal nerve (RLN). Materials and Methods: Retrospective analysis was performed on 145 cases of microinvasive esophageal cancer resection in the semi-prone position. Among which, 75 cases underwent complete freeing of the thoracic esophagus and subsequent scavenging of the PLNs of the left RLN from April 2011 to April 2012 (Group A). In the other 70 cases, the incompletely freed upper thoracic esophagus was suspended, and the PLNs of the left RLN were scavenged from May 2012 to April 2013 (Group B). Results: The average number of scavenged PLNs of the left RLN in Groups A and B was 4.6 ± 2.9 and 5.2 ± 3.0 pieces, respectively (P = 0.799). The total scavenged PLNs of the left RLN in Groups A and B were 344 and 357 pieces, respectively. Among which, the broken lymph nodes were 109 and 66 pieces, respectively (P < 0.0001). The postoperative hoarseness rate in Groups A and B was respectively 12.0% and 2.8% (P = 0.038). Conclusions: Dissection of the left RLN can be easily performed after esophageal suspension, thus ensuring the quality of PLN scavenging.

Abstract in Chinese

胸段食管癌半俯卧位胸腔镜下,用食管悬吊法清除左喉返神经周围淋巴结 摘要 目的:许多中国医生已经实施了半俯卧位微创食管癌切除术。然而,很少有报道以此用于左喉返神经(RLN)外周淋巴结清扫(PLNs)。 材料和方法:回顾性分析了半俯卧位微创食管癌切除术145例。其中,75例完全游离胸段食管,随后行左喉返神经外周淋巴结清扫(从2011年4月至2012年4月,A组)。其他70例,上胸段食管不完全游离并悬吊再行左喉返神经外周淋巴结清扫(从2012年5月到2013年4月,B组)。 结果:平均左喉返神经外周淋巴结清除数量,A和B组分别为4.6± 2.9和5.2± 3(P = 0.799)。总左喉返神经外周淋巴结清除数量,A和B组分别为344和357。其中,破碎的淋巴结分别为109和66(P<0.0001)。A和B组分别有12%和2.8%术后声音嘶哑率(P = 0.038)。 结论:食管悬吊后左喉返神经可以容易地进行解剖,从而确保外周淋巴结彻底清除的质量。 关键词:食管癌,淋巴结清除,喉返神经,胸腔镜
