EUS并ESD在直径≤1 cm的直肠神经内分泌肿瘤中的应用

Application of EUS and ESD in rNENs with diameter less than or equal to 1 cm

[目的]回顾性分析超声内镜(EUS)并内镜黏膜下剥离术(ESD)在直径≤1 cm的直肠神经内分泌肿瘤(rNENs)中的应用价值。[方法]纳入经结肠镜及EUS检查诊断为rNENs、直径≤1 cm的68例患者行ESD治疗。[结果]ESD后病理检查结果示68例为神经内分泌肿瘤;免疫组化分型35例为G1型,无G2型;病理结果切缘报告63例切缘阴性,完整切除率为92.6%;肠镜随访未发现有复发病例。[结论]直径≤1 cm的rNENs患者经EUS评估后,行ESD剥离,具有较高的完整切除价值及较好的预后。

[Objective]To retrospectively analyze the application value of endoscopic ultrasound(EUS)combined with endoscopicsubmucosal dissection(ESD)in rectal neuroendocrine tumors(rNENs)with diameter ≤1 cm.[Methods]Total 68 patients with diameter ≤1 cm who were diagnosed as rNENs by colonoscopy and EUS were enrolled for ESD treatment.[Results]Pathological examination after ESD showed that 68 cases were neuroendocrine tumors, including.35 cases were identified as G1 type without G2 type..The results showed that the resection margin was negative in 63 cases, and the complete resection rate was 92.6%.Colonoscopy follow-up showed no recurrence.[Conclusion]Patients with diameter ≤1 cm of rNENs evaluated by EUS and exfoliated by ESD have higher complete resection value and better prognosis.
