Résumé

Objective:To investigate the safety and mid-term efficacy of robotic versus laparoscopic total mesorectal excision surgery in rectal cancer.Methods:A total of 240 patients were diagnosed with rectal cancer at the Anorectal Department of Gansu Provincial Hospital from Aug 2015 to Mar 2021, 112 patients underwent laparoscopic total mesorectal excision (L-TME group) and 128 patients did robotic-assisted total mesorectal excision (R-TME group).Results:Compared to the R-TME group, the L-TME group had higher conversion rate (5.4% vs. 0.8%, χ2=4.417, P=0.036), higher incidence of complications (32.1% vs. 17.2%, χ2=7.290, P=0.007), higher circumferential resection margin involvement (7.1% vs. 1.6%, χ2=4.658, P=0.031), lower 3-year DFS and OS(74.1% vs. 85.2%, χ2=4.962, P=0.026) and (81.3% vs. 91.4%, χ2=5.494, P=0.019), lower 3-year DFS and OS in AJCC stage Ⅲ(52.5% vs. 76.1%, χ2=5.799, P=0.016) and (65.0% vs. 84.8%, χ2=4.787, P=0.029). Conclusion:R-TME can achieve better oncological outcomes and is more beneficial for RC patients compared with L-TME, especially for those with stage Ⅲ rectal cancers.

Résumé

Objective To compare effectiveness and short-term outcomes between robotic-assisted and laparoscopic surgery for radical resection of rectal cancer.Methods A total of 410 patients diagnosed with rectal cancer,undergoing robotic-assisted surgery (RAS) for rectal cancer (215 cases) and conventional laparoscopic surgery(CLS) for rectal cancer (195) from Jan 2016 to Dec 2018 were included into the present study.Operative characteristics,postoperative complications and pathologic parameters were evaluated between RAS and CLS group.Results The RAS group had less intraoperative blood loss[(107 ± 46) ml vs.(147 ±35)ml,t =3.695,P<0.05],longer operation time[(209 ±55)min vs.(195 ± 55)min,t=2.508,P<0.05],earlier first flatus[(3.4 ± 1.4)d vs.(5.3 ± 1.6)d,t =-14.952,P< 0.05],and first liquid diet time [(4.3 ± 1.5) d vs.(6.2 ± 2.6) d,t =-9.109,P < 0.05],more number of dissected lymph nodes[(12.6 ± 4.3) vs.(10.6 ± 4.5),t =4.468,P < 0.05] compared with those in the CLS group.But more expensive total hospitalization costs[(71 775 ±45 089) yuan vs.(66 789 ± 16 721) yuan,t =4.224,P < 0.05].Conclusion Compared with laparoscopic surgery,robotic-assisted surgery has less blood loss,shorter time of first flatus,more lymph nodes yield.
