BACKGROUND: Adoption of minimally invasive approaches continues to increase, and there is a need to reassess outcomes and cost. We aimed to compare open versus minimally invasive colectomy short- and long-term health-care utilization and payer/patient expenditures for benign disease.
METHODS: This is a retrospective analysis of IBM
RESULTS: Of 10,439 patients, 2531 (24.3%) had open, 6826 (65.4%) had laparoscopic, and 1082 (10.3%) had robotic colectomy. MIS patients had shorter length of stay (LOS; mean difference, - 1.71, p < 0.001) and lower average total expenditures (mean difference, - $2378, p < 0.001) compared with open patients during the index hospitalization. At 1 year, MIS patients had lower readmission rates, and fewer mean emergency and outpatient department visits than open patients, translating into additional savings of $5759 and 2.22 fewer days missed from work for health-care visits over the 365-day post-discharge period. Within MIS, RS patients had shorter LOS (mean difference, - 0.60, p < 0.001) and lower conversion-to-open rates (odds ratio, 0.31 p < 0.001) during the index hospitalization, and lower hospital outpatient visits (mean difference, - 0.31, p = 0.001) at 365 days than LS.
CONCLUSION: MIS colectomy is associated with lower mean health-care expenditures and less resource utilization compared to the open approach for benign disease at index operation and 365-days post-discharge. Health-care expenditures for LS and RS are similar but shorter mean LOS and lower conversion-to-open surgery rates were observed at index operation for the RS approach.
