Value of different anastomoses in laparoscopic radical right hemicolectomy for right-sided colon cancer: retrospective study and literature review

BACKGROUND: This study aimed to analyze the safety of circular lateral anastomosis and cross-lateral anastomosis in laparoscopic radical resection of right-sided colon cancer. METHODS: From January 2018 to March 2021, 147 patients with right-sided colon cancer were admitted to the Department of General Surgery, Cancer Hospital, Zhengzhou University. The experimental group comprised patients with circular lateral anastomosis, whereas the control group comprised patients with cruciform lateral anastomosis. The general clinical data, intraoperative features, and postoperative results of the two groups were compared and analyzed. RESULTS: Both groups successfully underwent laparoscopic lateral ileocolic anastomosis, with significant differences in anastomotic leakage (χ(2)=4.520, P < 0.05). By contrast, body mass index (t = 1.568, P = 0.119), histological typing (χ(2) = 2.067, P = 0.559), intraoperative bleeding (t = 0.418, P = 0.677), and intestinal obstruction (χ(2) = 2.564, P = 0.109) were not significantly different between the groups (P > 0.05). CONCLUSIONS: In laparoscopic-assisted radical hemicolectomy for right-sided colon cancer, the incidence of postoperative anastomotic leakage was lower with circular lateral anastomosis than with cross-lateral anastomosis, and circular lateral anastomosis was superior to cross-lateral anastomosis in terms of reducing the length of hospital stay and improving patients' postoperative quality of life.
