Retraction Note: Colorectal Infraperitoneal Anastomosis: The Effects of Perioperative Supplemental Oxygen Administration on the Anastomotic Dehiscence

Abstract

The Editors-in-Chief are retracting this article due to similarities to a previously published work entitled "Incidence, consequences, and risk factors for anastomotic dehiscence after colorectal surgery: a prospective monocentric study" by

RETRACTED: High-concentration supplemental perioperative oxygen and surgical site infection following elective colorectal surgery for rectal cancer: a prospective, randomized, double-blind, controlled, single-site trial

“…There were various reasons for administering oxygen for 6 hours after surgery. 34,35 It was known from previous studies that the relative anastomotic ischemia was transitory 36 and limited to the first 24 hours after surgery. Patients may tolerate a mask that delivers a high oxygen concentration for a few hours after surgery, but such concentration would be difficult to maintain for longer periods owing to patient discomfort; for this reason the supplemental oxygen therapy was restricted to 6 hours after surgery.…”

Incidence of surgical site infection in dogs undergoing soft tissue surgery: risk factors and economic impact

“…In human medicine, it is well known that hypotension, hypothermia and hypoxia contribute to the development of tissular hypo-oxygenation. Additionally, tissular hypo-oxygenation has been shown to be a risk factor in the development of SSI by numerous studies 26–32. As a result, most guidelines recommend maintaining optimal tissue oxygenation at all times 33.…”

Systematic review of preoperative, intraoperative and postoperative risk factors for colorectal anastomotic leaks

“…Hypothermia increases the risk of surgical‐site infections and induces vasoconstriction, but there is no conclusive evidence that it is a risk factor for AL. Hyperoxia (fraction of inspired oxygen 80 versus 30 per cent) reduced AL rates in open infraperitoneal colorectal anastomoses in a small RCT, and appears to confer a reduction in mortality.…”
