Clinical References Utilizing a Dual-Ring Wound Protector

Wound edge protector for prevention of surgical site infection in laparotomy: An updated systematic review and meta-analysis

Zhang MX, Sun YH, Xu Z, Zhou P, Wang HX, Wu YY

"Our exploratory meta-analysis suggests that [Wound Edge Protector] reduces the incidence of SSI in patients receiving laparotomies, especially in the circumstance of dual-ring WEP and in contaminated incisions. In order to fully assess the effectiveness of WEP, large-scale and well-designed RCTs are still needed in the future."

Plastic wound retractors as bacteriological barriers in gastrointestinal surgery: a prospective multi-institutional trial

Mohan HM, McDermott S, Fenelon L, Fearon NM, O'Connell PR, Oon SF, Burke J, Keane E, Shields C, Winter DC; Members of the University College Dublin Wound Retractor Study Group

A prospective, observational, multi-centre study including 250 patients obtained 500 samples for bacterial culture from the inside and outside surfaces of a plastic wound retractor. It was determined that use of a plastic wound retractor should result in the reduction of surgical site infection by reducing wound exposure to enteric bacteria in gastrointestinal surgery.

Wound Infection After Colorectal Surgery in the Laparoscopic Era

Nassif G, Ortiz D, Frenkel J, Berman S, Keller D, Marks G, Marks J

An analysis of 158 patients undergoing laparoscopic colon procedures determined that using a clean and dirty technique and wound protection dramatically reduces wound infections compared to historic controls.

Systematic Review of the Clinical Effectiveness of Wound-edge Protection Devices in Reducing Surgical Site Infection in Patients Undergoing Open Abdominal Surgery

Gheorghe A, Calvert M, Pinkney TD, Fletcher BR, Bartlett DC, Hawkins WJ, Mak T, Youssef H, Wilson S

A systematic review including 12 studies evaluating surgical site infection rate concluded that wound-edge protection devices may be efficient in reducing SSI rates in patients undergoing open abdominal surgery.

Effectiveness of using Wound Retractor for preventing post-operative SSI in colorectal surgeries (in Japanese)

Hirohashi Y, Kitagawa H, Okuyama K, Urata M, Hashiguchi K, Tanaka M, Tanaka T, Sato K

An analysis of methods of wound margin protection for 375 colorectal cases found that using no drape resulted in a 27.6% SSI rate (52 out of 190), using a ring drape resulted in a 24.3% SSI rate (18 out of 74), and using a wound retractor resulted in a 3.4% SSI rate (4 out of 118) – one-seventh of the ring drape SSI rate. Investigators consider that using the wound retractor is cost effective, especially for contaminated procedures such as colorectal surgery.

A Wound Protector Shields Incision Sites from Bacterial Invasion

Horiuchi T, Tanishima H, Tamagawa K, Sakaguchi S, Shono Y, Tsubakihara H, Tabuse K, Kinoshita Y

Bacterial swabs were taken from the incision margin and abdominal cavity side of a wound protector from 272 patients who underwent gastrointestinal surgery. The results suggest that the wound protector protects an incision site from bacterial damage.

Randomized Controlled Investigation of the Anti-Infective Properties of the Alexis Retractor/Protector of Incision Sites

Horiuchi T, Tanishima H, Tamagawa K, Matsuura I, Nakai H, Shouno Y, Tsubakihara H, Inoue M, Tabuse K

A randomized, controlled trial of 221 patients undergoing nontraumatic gastrointestinal surgery demonstrated a statistically significant decrease in superficial incisional surgical site infection when a wound protector/retractor was used. Results indicated that the use of the wound retractor would protect wounds from bacterial contamination and thus prevent infection.

Infection Rates Using Protectors in Laparoscopic Gastric Bypass

Im A, Zuccala K, Saldinger P

For laparoscopic gastric bypass procedures, the left lower quadrant incision used for tissue removal from the gastrotomy and enterotomy closure and EEA introduction for creating the gastrojejunostomy anastomosis experienced a significant decrease in wound infection incidences when a wound protector/retractor was used.

Plastic wound protectors do not affect wound infection rates following laparoscopic-assisted colectomy

Kercher KW, Nguyen TH, Harold KL, Poplin ME, Matthews BD, Sing RF, Heniford BT

A retrospective review of 141 patients undergoing laparoscopic-assisted colectomy using a wound protector concluded that although wound protectors are useful for mechanical retraction of smaller wounds, they do not significantly diminish the rate of post-operative wound infections.
