Aim:
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.
Patients And Methods:
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.
Results:
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 (p<0.001), as well as a significantly higher incidence of SSI (p=0.004).
Conclusion:
A significant higher incidence of SSI and TUI hernia in laparoscopic colorectal resection was found. The construction of the TUI was feasible with rationality.
