Comparison of short-term clinical effect between selective three-field lymphadenectomy and two-field lymphadenectomy for esophageal squamous cell carcinoma (ESCC) via video-assisted laparothoracoscopy / 中华胸心血管外科杂志

ABSTRACT

Objective To compare short-term clinical effect according to the extent of lymphadenectomy.To identify the rational lymph node dissection in patients with esophageal squamous cell carcinoma(ESCC).Methods Between January 2010 and December 2013,160 patients with ESCC received video-assisted laparothoracoscopy esophagectomy plus three-field lymphadenectomy(3FL) (86 cases)or two-field lymphadenectomy(2FL) (74 cases).Retrospectively analyzed the lymph node metastasis, postoperative complications and short-term survival rates between 3FL and 2FL.Results There was significantly differences in the number of lymph node between 3 FL(28.60 ± 3.30) and 2 FL(14.54 ± 5.59) (P ＜ 0.05) , but no significantly differences in postoperative complications between 3FL(22.09％) and 2FL(14.86％) (P ＞ 0.05).There was significantly differences in half-year survival rates between 3FL(93.02％) and 2FL(83.78％) (P ＜ 0.05).Conclusion Three field lymph oode dissection can reduce local recurrence, improve survival rate of some patients with ESCC.We suggest that esophagectomy plus three-field lymphadenectomy should be conventional.
