“Impervious plastic wound protectors reduce the risk of SSI when employed in
non-trauma-related gastrointestinal and biliary tract surgery. Wound protectors represent
a safe and simple intervention that may reduce postoperative morbidity and mortality.”
...
“There was a nonsignificant trend toward greater protective effect in studies using a dual
ring protector (RR = 0.31, 95% Cl 0.14-0.67, P = 0.003), rather than a single ring protector
(RR = 0.83, 95% Cl 0.38-1.83, P = 0.64).”
“In this study the use of barrier wound protection in elective open colorectal resectional surgery
resulted in a clinically significant reduction in incisional surgical site infections.”
...
“There was a significant reduction in the incidence of incisional surgical site infections when the
wound protector was used: 3 of 64 (4.7%) vs 15 of 66 (22.7%).”

Clinical Trial. Dis Colon Rectum. 2010 Oct; 53(10): 1374-1380.

2012 Jul; 256(1): 53-59.
“Our data demonstrate that a statistically significant reduction in the incidence of wound
infection was achieved with the use of a wound-protection device. This device provides a
simple intervention that may eventually have a large impact on the incidence of surgical
wound infection and therefore annual health care expenditures.”
“Superficial incisional SSI was significantly diminished in the ALEXIS wound retractor group
(P=0.006).”

“The ALEXIS wound retractor is more effective in preventing SSI in elective colorectal
resections compared with conventional methods.”

in colorectal resections. Colorectal Dis. 2012 Jun; 14(6): 346-351.
“[E]nteric organisms were cultured twice as often from the inside surface of the retractor
compared with the outside surface of the retractor (49% vs 26%, respectively; P < 0.0001).”

“We found that the wound retractor/protector prevented the incision site from drying,
decreased tissue damage, and facilitated the migration of neutrophils, suggesting a preventive
effect of the device with respect to wound infection.”

due to environmental factors experienced during surgery.”

“The results of this study demonstrate that wound infection decreased significantly in the
With Alexis retractor group.”
...
“Only the use of a wound protector was found to significantly reduce the risk of wound
infections in an adjusted analysis.”
“It was suggested that the use of the Alexis wound retractor would protect surgical wounds
from contamination by bacteria and thus prevent infection.”

“These results suggest that the [wound protector] protects an incision site from bacterial
invasion.”
...
“[W]e consider that the low incidence of SSI may have resulted from the protective effects of the
[wound protector].”

Wound Protectors/Retractors
“The wound infection rate of the [left upper quadrant] trocar site was significantly decreased
when utilizing the wound retractor (18% to 0%).”
“[U]se of a plastic wound retractor may result in reduced enteric bacterial colonization of the
surgical incision site during gastrointestinal surgery. Reduced colonization of the surgical
incision site by enteric bacteria due to the use of a plastic wound retractor should result in a
reduction in SSI following gastrointestinal surgery.”
“Laparoscopic colon and rectal resection using a clean and dirty technique, with sterile
specimen extraction, re-gowning procedure and wound protection have proven to reduce the
incidence of wound infections, for an overall SSI rate of 5.1% compared to previously reported
rates of up to 30%.”
