Abstract
Background
No previous study has compared the risk of surgical site infection (SSI) between intracorporeal anastomosis (IA) and extracorporeal anastomosis (EA) related to intra-abdominal infection in laparoscopic right hemicolectomy. Therefore, this study aimed to compare the risk of SSI in IA and EA in this context.
Methods
From July 2014 to March 2018, 101 consecutive (median age, 73 years; male, 54) patients underwent laparoscopic right hemicolectomy for colon cancer. The IA and EA groups consisted of 51 and 50 cases, respectively. After either IA or EA, lavage was performed with 100 mL of saline in the area surrounding the anastomosis, and a sample was collected for bacterial culture. The product of the virulence score and dose of bacterial contamination score called the risk of SSI score was evaluated in both groups, and short-term outcomes in both groups were analyzed retrospectively.
Results
No significant difference was found in patient characteristics between the 2 groups. The frequency of organ/space SSI in the IA group was significantly higher than that in the EA group (7.8% vs 0%, P = .04). The risk of SSI score was significantly higher in the IA group than in the EA group (median, 9 vs 1, P < .01).
Conclusions
Compared with EA, IA in laparoscopic right hemicolectomy increased organ/space SSI rates, signifying intra-abdominal infection. We strongly recommend prevention of intra-abdominal infection when performing an IA.
