Impact of perioperative probiotic treatment for surgical site infections in patients with colorectal cancer

摘要

The aim of the present study was to estimate the effect of the perioperative administration of probiotics in patients undergoing colorectal cancer (CRC) surgery. The study focused on a total of 156 consecutive surgeries carried out from among all the elective CRC surgeries performed between April 2009 and March 2013. The patients involved in surgeries undertaken between April 2009 and October 2011 were placed in the non-probiotic group (group A, 81 patients) and those involved in surgeries between November 2011 and March 2013 were placed in the probiotic group (group B, 75 patients). Postoperative infectious complications were recorded, and the immune responses and fecal microbiota were determined. A breakdown of infectious complications showed that 21 (13.5%) patients experienced superficial incisional surgical site infections (SSIs), of which 16 patients were from group A (19.8%), and five patients from group B (6.7%) (P=0.016). The ImmuKnow® adenosine triphosphate values peaked on the first postoperative day (POD) in both groups. In group A, the ImmuKnow value of the first POD was increased significantly compared with the preoperative value (P=0.022). In group B, the value of the first POD did not increase compared with the preoperative value (P=0.28). In conclusion, probiotic treatment can reduce superficial incisional SSIs in patients undergoing CRC surgery. Perioperative probiotic treatment can enhance immune responses and improve the intestinal microbial environment.
