For some time now, there has been significant interest in understanding and defining the role of minimally invasive surgery in colorectal cancer. Laparoscopic surgery has been shown to have similar or better outcomes compared with open surgery. Recently, prospective randomized trials have demonstrated oncologic outcomes of laparoscopic colon surgery equivalent to those for open surgery. However, the technical challenges of performing laparoscopic resection of rectal cancers and the uncertainty of the oncologic quality of the surgical resection have hindered the growth of minimally invasive rectal surgery. Robotic rectal surgery has recently emerged as an attractive alternative to laparoscopic surgery because it allows for superior visualization within a narrow pelvic field and more precise dissection. Studies of robotic rectal resection have suggested similar or potentially improved short-term oncologic outcomes when compared with laparoscopic rectal resection. Ongoing randomized studies will provide additional insight into the role of laparoscopic and minimally invasive robotic surgery for rectal cancer.
一段时间以来，人们对理解和界定微创手术在结直肠癌治疗中的作用有着浓厚兴趣。与开放手术相比，腹腔镜手术已被证明具有相似或更好的疗效。最近，前瞻性随机试验表明，腹腔镜结肠手术的肿瘤学疗效与开放手术相当。然而，进行腹腔镜直肠癌切除术的技术挑战以及手术切除肿瘤学质量的不确定性阻碍了微创直肠手术的发展。机器人直肠手术最近已成为腹腔镜手术的一种有吸引力的替代方法，因为它能在狭窄的盆腔区域实现更好的视野和更精确的解剖。与腹腔镜直肠切除术相比，机器人直肠切除术的研究表明短期肿瘤学疗效相似或可能有所改善。正在进行的随机研究将为腹腔镜和微创机器人手术在直肠癌治疗中的作用提供更多见解。
