Abstract:
Objective:To investigate the effects of total minimally invasive surgery (TMA) and mixed minimally invasive/open surgery (HMOA) on perioperative conditions and long-term efficacy of patients with rectal cancer.Methods:The clinical data of 240 patients with rectal cancer treated with minimally invasive surgery from January 2014 to August 2018 in Hangzhou Third People′s Hospital were retrospectively analyzed. Among them, 110 patients were treated with TMA (TMA group) and 130 patients were treated with HMOA (HMOA group). The relevant indexes of patients before and after surgery were collected and analyzed.Results:The operation time in TMA group was significantly longer than that in HMOA group: (312.5 ± 20.3) min vs. (210.8 ± 15.2) min, the length of hospital stay was significantly shorter than that in HMOA group: (4.0 ± 0.5) d vs. (6.8 ± 1.0) d, and there were statistical differences ( P<0.01); there were no statistical differences in low anterior resection and surgical procedures, ileostomy, open surgery, postoperative complications, reoperation, morphine dosage at 3 d after surgery and readmission between 2 groups ( P>0.05). Multivariate Cox analysis result showed that BMI ≥ 30 kg/m 2 ( OR=4.11, 95% CI 1.68 to 9.72, P<0.01), TMA ( OR=0.13, 95% CI 0.06 to 0.42, P<0.01), delayed bowel obstruction ( OR=13.6, 95% CI 1.59 to 110.56, P<0.05) and reoperation ( OR=15.32, 95% CI 5.52 to 42.56, P<0.01) were independent risk factors of prolonged hospital stay in patients with rectal cancer. The patients were followed up for 15 to 42 (29.5 ± 0.2) months, and there were no statistical differences in 3-year overall survival (OS) rate and 3-year disease-free survival (DFS) rate between HMOA group and TMA group (92.5% vs. 92.8% and 79.6% vs. 85.5%, HR=1.20 and 0.75, 95% CI 0.35 to 3.14 and 0.28 to 1.34, P=0.98 and 0.25). Conclusions:Patients with rectal cancer treated with TMA have the advantages of shorter hospital stay and shorter short-term effects compared with those treated with HMOA. However, the long-term effects of the two minimally invasive procedures are similar.
