Comparison of postoperative recovery of patients who underwent laparoscopic-assisted radical resection of right colon cancer with modified triangular anastomosis or tubular anastomosis: a retrospective cohort study.

<bold>Background: </bold>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.<bold>Methods: </bold>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.<bold>Results: </bold>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).<bold>Conclusion: </bold>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. [ABSTRACT FROM AUTHOR]
