BACKGROUND Studies find similar perioperative outcomes between single-incision laparoscopic surgery (SILS) and conventional laparoscopic surgery (CLS) for colon cancer. However, few have reported long-term outcomes of SILS versus CLS. We aimed to compare long-term postoperative and oncologic outcomes as well as perioperative outcomes between SILS and CLS for colon cancer. METHODS A total of 641 consecutive patients who underwent laparoscopic surgery for colon cancer from July 2009 to September 2014 were eligible for the study. Data from 300 of these patients were used for analysis after propensity score-matching (n = 150 per group). Variables associated with short- and long-term outcomes were analyzed. RESULTS The SILS group had a shorter mean total incision length, less postoperative pain, and a similar mean rate of incisional hernia (2.7% versus 3.3%) compared with the CLS group. The 7-year overall and disease-free survival rates were 92.7% versus 94% (p = 0.673) and 85.3% versus 84.7% (p = 0.688) in the SILS and CLS groups, respectively. CONCLUSIONS Compared with CLS, SILS for colon cancer appeared to be safe in terms of perioperative and long-term postoperative and oncologic outcomes. The results suggested that SILS is a reasonable treatment option for colon cancer for a selected group of patients.

结肠癌单切口腹腔镜手术的长期肿瘤学结果。

背景 研究发现单切口腹腔镜手术 (SILS) 和常规腹腔镜手术 (CLS) 治疗结肠癌的围手术期结局相似。然而，很少有人报告 SILS 与 CLS 的长期结果。我们旨在比较 SILS 和 CLS 治疗结肠癌的长期术后和肿瘤学结果以及围手术期结果。方法 2009 年 7 月至 2014 年 9 月共有 641 名连续接受腹腔镜结肠癌手术的患者符合研究条件。来自这些患者中的 300 名患者的数据在倾向评分匹配后用于分析（每组 n = 150）。分析了与短期和长期结果相关的变量。结果 SILS 组的平均总切口长度较短，术后疼痛较少，切口疝的平均发生率相似（2. 7% 对 3.3%）与 CLS 组相比。SILS 和 CLS 组的 7 年总生存率和无病生存率分别为 92.7% 和 94% (p = 0.673) 和 85.3% 和 84.7% (p = 0.688)。结论 与 CLS 相比，结肠癌的 SILS 在围手术期和长期术后和肿瘤学结果方面似乎是安全的。结果表明，对于选定的一组患者，SILS 是结肠癌的合理治疗选择。
