Purpose: The purpose of this study was to investigate the effects of postoperative complications on long-term survival after laparoscopic surgery for resectable colorectal cancer. Methods: We retrospectively included 204 patients who underwent laparoscopic surgery for colorectal cancer from January 2016 to June 2020. Results: Overall, 68 (33.3%) patients had postoperative complications, twelve (17.6%) of which were classified as Clavien–Dindo class 3a or higher. The 5-year overall survival rate of the non-complication and complication groups were 93.0% and 81.7%, respectively (p = 0.048; Kaplan–Meier analysis and log-rank test), and those among patients with stage III disease were 87.0% and 61.3%, respectively (p = 0.045). The 5-year disease-free survival rates were 85.6% and 77.4%, respectively (p = 0.042). Multivariable Cox proportional-hazards analysis revealed that nodal stage (hazard ratio, 8.392; 95% confidence interval, 1.892–37.175; p = 0.005) was an independent prognostic factor for overall survival, and postoperative complications (hazard ratio, 2.996; 95% confidence interval, 1.076–8.340; p = 0.036) were independent prognostic factors for disease-free survival. Conclusion: Postoperative complications were associated with poor oncological outcomes, especially among patients with stage III colorectal cancer, and independent prognostic factors for disease-free survival.

The article discusses the challenges of single-port laparoscopic surgery for left-sided colorectal cancer and introduces the ArtiSential instrument as a potential solution. A case study of a 42-year-old woman with obstructed sigmoid colon cancer who underwent surgery using the wristed articulated instrument is presented. The study highlights the benefits of articulated laparoscopic instruments in performing single-incision plus one-port laparoscopic anterior resections for left-sided colon cancer.

Aim: Surgical treatment of splenic flexure cancer (SFC) still presents some debated issues, including the role of laparoscopic surgery. The literature is based on small single‐centre series, while randomized controlled studies comparing open and laparoscopic treatment for colon cancer exclude SFC. This study aimed to determine the role of laparoscopic surgery in the treatment of SFC, comparing short‐ and long‐term outcomes with open surgery. Method: This was an international multicentre retrospective cohort study that analysed patients from 10 tertiary referral centres. From a cohort of 641 cases, 484 patients with Stage I–III SFC submitted to elective surgery with curative intent were selected. After 1:1 propensity score matching, 130 patients in the laparoscopic group (LapGroup) were compared with 130 patients in the open surgery group (OpenGroup). Results: After propensity score matching, the two groups were comparable for demographic and clinical parameters. OpenGroup presented a higher incidence of overall (P = 0.02) and surgery‐related complications (P = 0.05) but a similar rate of severe complications (P = 0.75). Length of stay was notably shorter in the LapGroup (P = 0.001). Overall (P = 0.793) as well as cancer‐specific survival (P = 0.63) did not differ between the two groups. Conclusions: Elective laparoscopic surgery for Stage I–III SFC is feasible and associated with improved short‐term postoperative outcomes compared to open surgery. Moreover, laparoscopic surgery appears to provide excellent long‐term cancer outcomes. [ABSTRACT FROM AUTHOR]

Purpose: The robotic single-port access plus one conventional robotic port, a reduced-port robotic surgery (RPRS) for left-sided colon cancer, can enable lymphovascular dissection using the wristed instrumentation and safe rectal transection through an additional port maintaining the cosmetic advantage of the single-port surgery. The aim of this study is to compare the clinicopathological outcomes between reduced-port and conventional multi-port robotic colectomy for left-sided colon cancer.Methods: The study group included 23 patients who underwent an RPRS and 16 patients who underwent a multi-PRS (MPRS) for left-sided colon cancer between August 2013 and January 2016.Results: The operative time was significantly shorter in the RPRS group than in the MPRS group (mean time 258 ± 67 vs. 319 ± 66 minutes, P = .009). There were no apparent differences in tolerance of diet, postoperative pain score, length of hospital stay, the rate of postoperative complications, and the mean number of harvested lymph node, but the RPRS group had a significantly smaller total incision length (38 ± 12 mm vs. 83 ± 6 mm, P = .013).Conclusions: This study shows the feasibility and safety of the RPRS, with clinicopathological outcomes that is comparable with that of the MPRS for left-sided colon cancer.
