目的

对比基于精准吻合器和刘氏吻合三步法的改良PPS术与传统PPS术治疗超低位直肠癌的临床疗效。

方法

前瞻性收集自2019年6月至2021年5月行超低位直肠癌精准功能保肛术(PPS术)的患者数据,根据手术方式分为传统PPS组(传统组)和基于精准吻合器和刘氏吻合三步法的改良PPS术(改良组),并对比两组患者的临床资料(包括基线情况、病理学情况、围手术期恢复指标等)。

结果

共纳入135例患者资料,其中传统组110例,改良组25例。两组患者基线水平和病理学情况差异均无统计学意义,术中出血(127 mL vs. 125 mL)、手术时间(207 min vs. 219 min)、远切缘距离(1.2 cm vs. 1.3 cm)、术后住院时间(13.5 d vs. 12.4 d)、手术费用(64 661.3 RMB vs. 62 096.8 RMB)等差异均无统计学意义。改良PPS术显著降低预防性造口比例(37.3% vs. 12%,P=0.015)、总体并发症发生率(32.7% vs. 12.0%,P=0.039)和吻合口漏发生率(22.7% vs. 0%,P=0.008)。

结论

基于精准吻合器和刘氏吻合三步法的改良PPS术显著降低预防性造口比例和吻合口漏风险,具有广阔的前景和良好的社会经济效益。

Objective

To compare the clinical outcomes of the conventional precision functional sphincter-preserving surgery (PPS) with modified PPS based on precision anastomosis and Liu's three-step anastomosis in the treatment of ultra-low rectal cancer.

Methods

Data of patients with ultra-low rectal cancer who underwent PPS from June 2019 to May 2021 were prospectively collected. Patients were divided into two groups, namely the conventional group and modified group. Baseline characteristics, pathological data, and postoperative outcomes were compared between the two groups.

Results

A total of 135 patients were included, including 110 cases in the conventional group and 25 cases in the modified group. There was no significant difference in baseline characteristics and pathological data between two groups, including intraoperative bleeding (127 mL vs. 125 mL), operation time (207 min vs. 219 min) and distal resection margin (1.2 cm vs. 1.3 cm). There was no significant difference in postoperative hospital stay (13.5 days vs. 12.4 days) and operation cost (64 661.3 RMB vs. 62 096.8 RMB). The modified PPS significantly reduced the proportion of prophylactic stoma (37.3% vs. 12%, P=0.015), the overall incidence of complications (32.7% vs. 12.0%, P=0.039) and the incidence of anastomotic leakage (22.7% vs. 0%, P=0.008).

Conclusion

Modified PPS that based on precision anastomosis and Liu's anastomosis can significantly reduce the proportion of prophylactic stoma and the risk of anastomotic leakage, which has a broad prospect and good socioeconomic benefits.
