Abstract
INTRODUCTION: Whether creation of omental pedicle flap (OPF) to reinforce bowel anastomosis can reduce septic outcomes remains controversial. The aim of this study was to investigate the role of this technique on anastomotic leak and septic complications after rectal cancer surgery. METHODS: Patients who underwent rectal cancer surgery from 01/2008 to 12/2013 were identified and categorized into two groups based on OPF creation versus no-OPF creation. Clinical, operative characteristics and postoperative anastomotic leak and surgical site infections within 30 days after surgery were compared between the groups. RESULTS: There were 65 (14%) and 403 (86%) patients in OPF and no-OPF group, respectively. In multivariate analysis, OPF was not found to be associated with anastomotic leak (p = 0.35), organ/space infections (p = 0.99) and overall surgical site infections (p = 0.65). Three hundred and sixty eight (78.6%) patients underwent diversion. OPF did not reduce septic complications irrespective of the stoma status (p > 0.05). There were no differences between the two groups in terms of operative (p = 0.46) and non-operative management (p = 0.14). CONCLUSION: OPF neither reduced the incidence of anastomotic leak and surgical site infections nor had any impact on the management of anastomotic leak.
