右半结肠切除是目前治疗右半结肠癌最主要也是有效的方法，随着外科技术的发展，右半结肠切除也迎来了许多新的手术方式和挑战，从开腹手术到腹腔镜手术，微创外科受到了外科医生重点学习和关注。目前越来越多的患者从微创手术中获益也引起了结直肠外科医生对右半结肠切除的微创技术进行新的挑战。从原来的常规五孔腹腔镜到三孔腹腔镜的探索和单孔腹腔镜的创新也引发了更多的关注和争议。而机器人的应用代表外科技术的又一大进步，机器人手术对于患者术后早期恢复和获得淋巴结数目优于腹腔镜手术，但机器人手术是否会为患者带来远期获益则是现阶段主要的研究目标。除此之外目前对于右半结肠切除形成的统一理念是全结肠系膜切除（CME），而是否还需进行D3淋巴结清扫则是讨论的热点话题；右半结肠切除术后回结肠吻合亦成为目前关注的问题，体内吻合和体外吻合尚未形成统一意见其主要关注点在于腹腔感染的发生情况，本文将就右半结肠切除研究过程中存在的热点话题和争议做一综述。

Right hemicolectomy is currently the most important and effective method for the treatment of right hemicolectomy. With the development of surgical technology, right hemicolectomy has also ushered in many new surgical methods and challenges. From open surgery to laparoscopic surgery, minimally invasive surgery has attracted the attention of surgeons. At present, more and more patients benefit from minimally invasive surgery, which also motivates colorectal surgeons to take on new challenges with minimally invasive techniques for right hemicolectomy. The exploration from conventional five-hole laparoscopy to three-hole laparoscopy and the innovation of single-hole laparoscopy have also aroused more attention and controversy. However, the application of robot represents another great progress in surgical technology. Robotic surgery is better than laparoscopic surgery for early postoperative recovery and the number of lymph nodes obtained. However, whether robotic surgery can bring long-term benefits to patients is the main research goal of surgeons. In addition, the current unified idea for right hemicolectomy is total mesocolectomy and whether D3 lymph node dissection is a hot topic of discussion. Ileocolon anastomosis after right hemicolectomy has also become a problem of current concern. No consensus has been reached between in vivo anastomosis and in vitro anastomosis, and the main concern is the occurrence of abdominal infection. This paper will review the hot topics and controversies in the study of right hemicolectomy.
