Background and Aims: The intersphincteric resection (ISR) is beneficial for saving patients' anus to a large extent and restoring original bowel continuity. Laparoscopic ISR (L-ISR) has its drawbacks, such as two-dimensional images, low motion flexibility, and unstable lens. Recently, da Vinci robotic ISR (R-ISR) is increasingly used worldwide. The purpose of this article is to compare the feasibility, safety, oncological outcomes, and clinical efficacy of R-ISR vs. L-ISR for low rectal cancer.Methods: PubMed, EMBASE, Cochrane Library, and Web of Science were searched to identify comparative studies of R-ISR vs. L-ISR. Demographic, clinical, and outcome data were extracted. Mean difference (MD) and risk ratio (RR) with their corresponding confidence intervals (CIs) were calculated.Results: Five studies were included. In total, 510 patients were included, of whom 273 underwent R-ISR and 237 L-ISR. Compared with L-ISR, R-ISR has significantly lower estimated intraoperative blood loss (MD = −23.31, 95% CI [−41.98, −4.64], P = 0.01), longer operative time (MD = 51.77, 95% CI [25.68, 77.86], P = 0.0001), hospitalization days (MD = −1.52, 95% CI [−2.10, 0.94], P < 0.00001), and postoperative urinary complications (RR = 0.36, 95% CI [0.16, 0.82], P = 0.02).Conclusions: The potential benefits of R-ISR are considered as a safe and feasible alternative choice for the treatment of low rectal tumors.

Abstract Purpose The aim of the study is to evaluate the surgical and oncology outcomes between laparoscopic Intersphincteric Resection (LISR) and laparoscopic-assisted Abdominoperineal Resection (LARC) for ultra-low rectal cancer patients by using a retrospective analysis, and a meta-analysis of the literature was carried out to further validate the oncology outcome. Patients and methods: Between April 2014 and December 2015, a total of 38 rectal cancer patients who underwent LISR and 41 LARC patients were enrolled in this study. The comparison between the groups was based on clinicopathological characteristics and surgical outcomes. Meta-analysis of published studies, exploring oncology outcome of between LISR and LARC, was carried out using STATA 12.0 software. Results Operating time, blood loss, length of hospital stay, and postoperative complication rates was similar between LISR group and LARC group; Patients undergoing LISR also had a similarly 5-year local recurrence and overall survival rate with LAPR. Meta-analysis showed that five studies, which included a total of 791 patients were final involved for this analysis. Comparing APR, ISR patients obtain similarly 5-years recurrence rate and 5-years survival rate. Conclusion This study suggests that LISR is as technically feasible, safe, and effective as LARC for treating patients with low rectal cancer. Additional high-powered randomized trials are needed to determine whether LISR truly offers any advantages.

Background. Abdominoperineal resection (APR) has been the standard surgery for ultra-low rectal cancer for a century. In recent years, intersphincteric resection (ISR) has been increasingly used to avoid the permanent colostomy. Up to now, there is no relevant meta-analysis comparing the clinical efficacy of ISR and APR. This meta-analysis aimed to compare the outcomes of these 2 procedures. Methods. A comprehensive search of online databases was performed on PubMed, EMBASE, and the Cochrane Library to obtain comparative studies of ISR and APR. Then the data from studies that met the inclusion criteria were extracted and analyzed. Results. A total of 12 studies covering 2438 patients were included. No significant differences were found between ISR and APR in gender, body mass index, distance from tumor to anal edge, operative time, and blood loss. In addition, hospital stay (weighted mean differences = −2.98 days; 95% confidence interval [CI] = −3.54 to −2.43; P < .00001) and postoperative morbidity (odds ratio [OR] = 0.76; 95% CI = 0.59 to 0.99; P = .04) were significantly lower in ISR group compared with APR group. However, patients who underwent ISR showed lower pathological T-stage (T3T4%, OR = 0.49; 95% CI = 0.28 to 0.86; P = .01) and lymph node metastasis rate (OR = 0.77; 95% CI = 0.59 to 1.01; P = .06) compared with those who underwent APR. Moreover, oncological outcomes were similar between the 2 groups. Conclusion. ISR may provide a safe alternative to APR, with shorter hospital stays, lower postoperative morbidity, and similar oncological outcomes. Well-designed randomized controlled trials are needed to confirm and update the findings of this analysis.
