目的

探究腹腔镜远端胃D2根治术联合全系膜切除(TME)方案应用于进展期胃癌患者的临床疗效及安全性。

方法

选取2019年3月至2023年3月收治的253例进展期胃癌病例开展回顾性队列研究。根据手术方法分组,121例患者采用腹腔镜远端胃D2根治术联合TME治疗,纳入A组,132例患者采用腹腔镜远端胃D2根治术治疗,纳入B组,采用倾向性评分匹配两组患者的资料,最终配对病例106对。符合正态分布的计量资料以(

±s)表示,组间差异通过独立样本t检验分析;并发症发生率等计数资料的组间差异通过χ2检验分析;生存结局通过Kaplan-Meier法绘制生存曲线,组间生存情况的差异采用Log-Rank检验。

结果

与B组相比,A组手术时间较短、术中出血量较少、区域淋巴结清扫数目更多(P<0.05);两组R0切除率比较,差异无统计学意义(P>0.05)。A组患者肛门排气、首次进食、腹腔引流及术后住院时间均短于B组(P<0.05)。重建方式分层分析显示,A组、B组内部不同重建方式间并发症发生率差异无统计学意义(P>0.05)。A组患者切口感染、腹腔感染及胃肠功能紊乱发生率低于B组(P<0.05)。两组吻合口漏、吻合口出血及肠梗阻发生率比较,差异无统计学意义(P>0.05)。A组患者术后1年、3年无进展生存率和总生存率均高于B组,A组患者无进展生存期和总生存期也比B组长(P<0.05)。A组患者术后1年和3年复发率均低于B组(P<0.05)。

结论

进展期胃癌患者采用腹腔镜远端胃D2根治术联合TME治疗,可优化围手术期相关指标,加快术后康复进程,降低部分并发症发生风险,同时对生存预后有改善作用。

Objective

To investigate the clinical efficacy and safety of laparoscopic distal gastrectomy with D2 resection combined with total mesorectal excision (TME) in patients with advanced gastric cancer.

Methods

A retrospective cohort study was conducted on 253 cases of advanced gastric cancer admitted to our hospital from March 2019 to March 2023. The patients were grouped according to the surgical method. 121 patients underwent laparoscopic distal gastrectomy with D2 resection combined with TME and were included in group A, while 132 patients underwent laparoscopic distal gastrectomy and were included in group B. The data of the two groups were matched by propensity score, and finally 106 pairs of matched cases were obtained. Quantitative data that followed a normal distribution were expressed as (

±s), and the differences between the groups were analyzed by independent sample t test; the differences in count data such as complication rates were analyzed by χ2 test; survival outcomes were plotted using the Kaplan-Meier method, and the differences in survival conditions between the groups were analyzed using the Log-Rank test.

Results

Compared with group B, group A had shorter operation time, less intraoperative blood loss, and more regional lymph node dissections (P<0.05); there was no statistically significant difference in R0 resection rate between the two groups (P>0.05). The time to anal exhaust, first meal intake, abdominal drainage, and postoperative hospital stay in group A were shorter than those in group B (P<0.05). Stratified analysis of reconstruction methods showed that there was no statistically significant difference in the incidence of complications among different reconstruction methods within groups A and B (P>0.05). The incidence of incision infection, abdominal infection, and gastrointestinal dysfunction in group A was lower than that in group B (P<0.05). There was no statistically significant difference in the incidence of anastomotic leakage, anastomotic bleeding, and intestinal obstruction between the two groups (P>0.05). The 1-year and 3-year disease-free survival rate and overall survival rate of group A were higher than those of group B, and the disease-free survival period and overall survival period of group A were also longer than those of group B (P<0.05). The recurrence rate of group A was lower than that of group B at 1 year and 3 years (P<0.05).

Conclusion

For patients with advanced gastric cancer, laparoscopic distal gastrectomy with D2 resection combined with TME can optimize perioperative indicators, accelerate the postoperative recovery process, reduce the risk of some complications, and improve survival prognosis.
