Increased Transumbilical Incision Complication Rates With Laparoscopic Colorectal Resection: A Single-center Propensity Score-matched Cohort Study

To evaluate the complication rates and risk factors associated with transumbilical incision (TUI) and comprehensively examine differences according to the procedures using propensity score matching.The study involved 737 patients who underwent laparoscopic procedures between 2009 and 2017 (Japanese University-Hospital-Medical-Information-Network Clinical Trials Resistry No. 000040653). The occurrences of superficial surgical site infection (SSI) and TUI hernia were analyzed.SSI occurred in 17 patients (2.31%) and hernia occurred in 29 (3.93%). Multivariate analysis revealed that female sex and diabetes mellitus were correlated with incisional hernia. Propensity score-matching analysis was performed to compare those who underwent colorectal resection with those who underwent other resections; the results showed that the former had a significantly higher rate of TUI hernia (p0.001), as well as a significantly higher incidence of SSI (p=0.004).A significant higher incidence of SSI and TUI hernia in laparoscopic colorectal resection was found. The construction of the TUI was feasible with rationality.
