An Assessment of the Clinical and Economic Impact of Establishing Ileocolic Anastomoses in Right-Colon Resection Surgeries Using Mechanical Staplers Compared to Hand-Sewn Technique

Abstract

Purpose. To estimate and compare clinical outcomes and costs associated with mechanical stapling versus hand-sewn sutured technique in creation of ileocolic anastomoses after right sided colon surgery.Methods. A previously conducted meta-analysis was updated for estimates of anastomotic leak rates and other clinical outcomes. A value analysis model was developed to estimate cost savings due to improved outcomes in a hypothetical cohort of 100 patients who underwent right colon surgery involving either mechanical stapling or hand-sewn anastomoses. Cost data were obtained from publicly available literature.Results. Findings from the updated meta-analysis reported that the mechanical stapling group had lower anastomotic leaks 2.4%  n=11/457compared to the hand-sewn group 6.1% leaksn=44/715. Utilizing this data, the value analysis model estimated total potential cost savings for a hospital to be around $1,130,656 for the 100-patient cohort using mechanical stapling instead of hand-sewn suturing, after accounting for incremental supplies cost of $49,400. These savings were attributed to lower index surgery costs, reduced OR time costs, and reduced reoperation costs driven by lower anastomotic leak rates associated with mechanical stapling.Conclusion. Mechanical stapling can be considered as a clinically and economically favorable option compared to suturing for establishing anastomoses in patients undergoing right colon surgery.
