SiewertⅡ型食管胃结合部腺癌的外科治疗

Surgical treatment for Siewert typeⅡadenocarcinoma of esophagogastric junction

外科手术是SiewertⅡ型食管胃结合部腺癌的主要治疗方式,但该部位的肿瘤具有独特的解剖结构及生物学特征,导致其淋巴转移途径、肿瘤浸润范围等较复杂,为其手术方式、切除范围及消化道重建等带来挑战与争议。本文将围绕以上几点,基于现有的循证医学证据,结合自身临床经验及前期研究结果,探讨目前SiewertⅡ型食管胃结合部腺癌外科的治疗策略。

Surgical intervention is the primary treatment option for Siewert typeⅡadenocarcinoma of the esophagogastric junction(AEG).Nevertheless,the unique anatomy and biology of tumors in this region make lymphatic metastasis and tumor infiltration extent highly complex.Consequently,there are challenges and controversies regarding surgical methodology,resection range,and reconstruction of digestive tracts.In this article,we will probe the current surgical management of Siewert typeⅡAEG on the basis of available evidence-based medical evidence,our own clinical experience and previous research.
