Observational methods to assess the effectiveness of screening colonoscopy in reducing right colon cancer mortality risk: SCOLAR

AbstractSingle-incision laparoscopic surgery (SILS) has the potential to improve perioperative outcomes, including less postoperative pain, shorter operation time, less blood loss, and shorter hospital stay. However, SILS is technically difficult and needs a longer learning curve. Between April 2016 and September 2019, a total of 198 patients with clinical stage I/II right colon cancer underwent curative resection. In the case of the SILS approach, an organ retractor was usually used to overcome SILS-specific restrictions. The patients were divided into two groups by surgical approach: the SILS with organ retractor group (SILS-O, n = 33) and the conventional laparoscopic surgery group (LAC, n = 165). Clinical T status was significantly higher in the LAC group (p = 0.016). Operation time was shorter and blood loss was lower in the SILS-O group compared to the LAC group (117 vs. 197 min, p = 0.027; 10 vs. 25 mL, p = 0.024, respectively). In the SILS-O group, surgical outcomes including operation time, blood loss, number of retrieved lymph nodes, and postoperative complications were not significantly different between those performed by experts and by non-experts. Longer operation time (p = 0.041) was significantly associated with complications on univariate and multivariate analyses (odds ratio 2.514, 95%CI 1.047–6.035, p = 0.039). SILS-O was safe and feasible for right colon cancer. There is a potential to shorten the learning curve of SILS using an organ retractor.

Abstract Background We compared the advantages and disadvantages of modified triangular anastomosis and tubular anastomosis for digestive tract reconstruction in patients undergoing laparoscopic-assisted radical resection of right colon cancer. Methods This was a retrospective cohort analysis of 92 cases of laparoscopic-assisted resection of right colon cancer, treated from June 2017 to June 2018, at the Huai’an No. 1 People’s Hospital in China. Patients were divided into a modified triangular anastomosis group (n = 33) and a tubular anastomosis group (n = 59). In the modified triangular anastomosis group, digestive tract reconstruction was conducted using side-to-side anastomosis of the ileo-transverse colon with a 60-mm linear stapler. The common entry hole was closed with a running suture. The tubular anastomosis group underwent end-to-side anastomosis of the ileo-transverse colon with a tubular stapler anchor placed at the end of the ileum. Results At baseline and perioperatively, there were no significant between-group differences in age, sex, body mass index, tumor location, pathological stage, or tumour size (P > 0.05). There were also no significant between-group differences in operation time, estimated blood loss, the number of harvested lymph nodes, the first postoperative flatulence time, hospitalisation time, or postoperative complications (P > 0.05); however, the total cost of hospitalization for the triangular anastomosis group was significantly lower than the tubular anastomosis group (P < 0.05). Conclusion Modified triangular anastomosis is a safe and feasible procedure for laparoscopic-assisted radical resection of right colon cancer. These results affirm the safety and effectiveness of total laparoscopic radical resection of right colon cancer. Given the equivalent outcomes between the two procedures, the modified triangular procedure may be more a more cost-effective option for clinical application.
