Background
The incidence of surgical site infection (SSI) is reportedly lower in laparoscopic colorectal surgery than in open surgery, but data on the difference in SSI incidence between colon and rectal laparoscopic surgeries are limited.
Methods
The incidence and risk factors for SSI, and the effect of oral antibiotics in colon and rectal laparoscopic surgeries, were investigated as a sub-analysis of the JMTO-PREV-07-01 (a multicenter, randomized, controlled trial of oral/parenteral vs. parenteral antibiotic prophylaxis in elective laparoscopic colorectal surgery).
Results
A total of 582 elective laparoscopic colorectal resections, comprising 376 colon surgeries and 206 rectal surgeries, were registered. The incidence of SSI in rectal surgery was significantly higher than in colon surgery (14 vs. 8.2 %, P = 0.041). Although the incidence of incisional SSI was almost identical (7 %) between the surgeries, the incidence of organ/space SSI in rectal surgery was significantly higher than in colon surgery (6.3 vs. 1.1 %, P = 0.0006). The lack of oral antibiotics was significantly associated with the development of SSI in colon surgery. Male sex, stage IV cancer, and abdominoperineal resection were significantly associated with SSI in rectal surgery. The combination of oral and parenteral antibiotics significantly reduced the overall incidence of SSI in colon surgery (relative risk 0.41, 95 % confidence interval 0.19–0.86).
Conclusion
The incidence of SSI in laparoscopic rectal surgery was higher than in colon surgery because of the higher incidence of organ/space SSI in rectal surgery. The risk factors for SSIs and the effect of oral antibiotics differed between these two procedures.
