- Abstract: Objective To explore the efficacy and safety of side-to-side anastomosis(SS)and end-to-side anastomosis(ES)of the ileocolon in laparoscopic right hemicolectomy of colon cancer,so as to provide evidence-based evidence for surgical selection.Methods PubMed,Embase,Web of Science,Cochrane Library,China National Knowledge Infrastructure,Wanfang Data,VIP database,Chinese BioMedical Literature database were searched from inception to November 2024 to collect relevant clinical studies of SS versus ES.The Newcastle-Ottawa Scale(NOS)was used to evaluate the literature quality of retrospective studies,and the Cochrane system was used to evaluate the literature quality of randomized controlled trials(RCT).Rev Man 5.3 software was used for Meta-analysis,sensitivity analysis,and publication bias analysis.Results 9 retrospective studies and 4 RCTs with a total of 2 632 patients were included.The Meta-analysis results of the retrospective study show that:Compared with SS,ES has a shorter tolerance time for liquid diet(MD=-0.20,95%CI:-0.40～0.00,P<0.05),fewer daily episodes of diarrhea(MD=-1.06,95%CI:-1.79～0.23,P<0.05),but a higher pain score at 12 hours post-surgery(MD=0.95,95%CI:0.50～1.40,P<0.05).Comparison of the overall complication rates of the two anastomosis methods showed no statistically significant difference((OR)=1.05,95%CI:0.22～5.14,P>0.05).Sensitivity analysis of the retrospective study shows:the incidence of ES bowel obstruction was higher than that of SS,with a statistically significant difference((OR)=2.18,95%CI:1.15～4.14,P<0.05);The sensitivity analysis of the RCT shows:the overall incidence of complications at the anastomotic site of SS was significantly higher than that of ES,with a statistically significant difference((OR)=5.26,95%CI:1.91～14.48,P<0.05),and the results of other outcome indicators did not show reversal.The analysis of publication bias risk showed no significant publication bias.Conclusion Ileocolonic ES has a slight advantage over SS in laparoscopic right hemicolectomy of colon cancer,both anastomoses are safe and effective,and the surgeon can choose the appropriate anastomosis technique according to the patient's specific situation,in order to improve the postoperative recovery.
