目的 观察内镜黏膜剥离术（ESD）下治疗早期食管癌的疗效及安全性。 方法 以2009年1月－2012年6月在我院消化内镜中心就诊的患者为研究对象，以内镜黏膜切除术（EMR）为对照，回顾性分析接受ESD和EMR治疗的共75例早期食管癌患者的临床资料，比较两组患者病灶整块切除率、组织学治愈切除率、手术时间及并发症等。 结果 共纳入75例患者，其中41例患者接受ESD治疗，34例接受EMR治疗。ESD和EMR组病灶整块切除率分别为90.2%（37/41）和44.1%（15/34）；治愈切除率分别为78.0%（32/41）和50.0%（17/34），整块切除率（P＜0.001）和治愈切除率（P=0.011）在两组间的分布差异均有统计学意义。ESD组患者手术平均时间（39.5 ± 11.4）min，而EMR组手术平均时间（33.5 ± 18.6）min，但二者之间的差异无统计学意义（P=0.091）。此外，术后延长出血和穿孔等并发症在两组间的分布亦无明显差异。 结论 早期食管癌患者接受ESD治疗可获得更高的整块切除率和组织学治愈切除率。
ObjectiveTo explore the feasibility and clinical efficacy of laparoscopic sentinel lymph node biopsy combined with endoscopic submucosal dissection(ESD) for patients with early gastric cancer(EGC). MethodsThe clinical data of 26 cases who received ESD combined with laparoscopic sentinel lymph node biopsy for EGC between March 2009 to August 2013 in Affiliated Hospital of Jiangnan University were analyzed retrospectively. These patients first underwent laparoscopic sentinel lymph node(SLN) biopsy. If frozen sectioning examination suggested there was lymph node metastasis, laparoscopic D2 radical gastrectomy would be operated. However, the ESD would be operated if the frozen sectioning examination was negative. ResultsThe total numbers of SLN were 95, and mean numbers of SLN were 3.7±1.4(range from 1 to 6). Two patients with positive SLN underwent laparoscopic-assisted distal gastrectomy and 24 patients with negative SLN underwent ESD. The disease free survival(DFS) and local recurrence rate after ESD for EGC was 91.7%(22/24) and 4.2%(1/24), respectively. And the total DFS for all patients was 96.2% (25/26). ConclusionESD for EGC is a safe and feasible procedure, combined with laparoscopic sentinel lymph node biopsy conforms more to the concept of principle of radical operation.
