“…For the laparoscopic groups, these data varied from 12.2 % [12] to 20 % [11]. However, no significant differences were found between groups, either by studies or by meta-analysis of pooled data [23,29]. In the present study, we found no significant differences in terms of complications between laparoscopic and robotic TME, although there were numerically fewer complications in the robotic group.…”

The aim of our study was to compare short-term outcomes of robotic and laparoscopic sphincter-saving total mesorectal excision (TME) in male patients with mid-low rectal cancer (RC) after neadjuvant chemoradiotherapy (NCRT). The study was conducted as a retrospective review of a prospectively maintained database, and we analyzed 14 robotic and 65 laparoscopic sphincter saving TME (R-TME and L-TME, respectively) performed by one surgeon between 2005 and 2013. Patient characteristics, perioperative recovery, postoperative complications and and pathology results were compared between the two groups. The patient characteristics did not differ significantly between the two groups. Median operating time was longer in the R-TME than in the L-TME group (182 min versus 140 min). Only two conversions occurred in the L-TME group. No difference was found between groups regarding perioperative recovery and postoperative complication rates. The median number of harvested lymph nodes was higher in the RTME than in the L-TME group (32 versus 23, p = 0.008). The median circumferential margin (CRM) was 10 mm in the R-TME group, 6.5 mm in the L-TME group (p = 0.047. The median distal resection margin (DRM) was 27.5 mm in the R-TME, 15 mm in the L-TME group (p = 0.014). Macroscopic grading of the specimen in the R-TME group was complete in all patients. In the L-TME group, grading was complete in 52 (80%) and incomplete in 13 (20%) cases (p = 0.109). R-TME is a safe and feasible procedure that facilitates performing of TME in male patients with mid-low RC after NCRT.

“…In rectal carcinoma, a meta-analysis indicates that the convention to open rate is lower for robotic assistance than the traditional LS (OR ¼ 0.31, 95% CI: 0.12 to 0.78), which is consistent with our results in rectal adenocarcinoma subgroup (OR ¼ 0.17, 95% CI: 0.06 to 0.46), but the EBL is not different between the two approaches. 32 This result seems inconsistent with our findings, however, we should note that in Ortiz-Oshiro's study, there were only two authors who reported the relevant data regarding EBL, 32 which might cause publication bias. Boggi et al provide positive evidence that laparoscopic robot-assisted total pancreatectomies significantly reduce the mean blood loss compared with open total pancreatectomies (220 vs. 705 mL, p ¼ 0.004).…”

In order to compare the curative effect of the Da Vinci surgical system (DVSS) with laparoscopic surgery (LS) or open surgery for colorectal resection, literature search was conducted in PubMed, Excerpt Medica Database (Embase), and Cochrane library up to January 15, 2016. Odds ratio (OR) and weighted mean difference with their corresponding 95% confidence intervals were used as effect size for evaluation of different outcomes. In total, 10 studies consisting of 2767 patients were included for the meta-analysis. As a result, there were no significant differences between DVSS and LS/open surgery in the long-term oncologic outcomes (p > 0.05). However, DVSS achieved a significantly lower length of hospital stay and estimated blood loss (EBL), but a longer operation time. Moreover, DVSS showed a significantly reduced conversion to open surgery than LS (OR ¼ 0.19, 95% confidence interval: 0.08-0.48). Subgroup analysis indicated that DVSS had different results in rectal adenocarcinoma and colon cancer subgroups on outcomes of conversion to open surgery and operation time. DVSS is superior to LS/open surgery in length of hospital stay and EBL, but needs longer operation time. Long-term outcomes of DVSS are comparable with the other approaches. From long-term perspective, DVSS has an equivalent effect to the other two techniques.

“…The overall results compare favorably with those of the standard approaches . Even more interesting, less conversion to open has been reported after robotic low anterior resections when compared with laparoscopy .…”

Robotic assistance may reduce conversion to open in rectal carcinoma laparoscopic surgery: systematic review and meta‐analysis

Abstract: This meta-analysis of available non-randomized studies suggests that conversion to open rate may be reduced when using RARS instead of LARS for rectal cancer.
