Plastic wound protectors reduce infection rate after laparoscope-assisted colectomy
Plastic wound protectors, applied to the extraction incision, can reduce postoperative wound infection rates in laparoscope-assisted colectomy, a new cohort study has shown.
There were 109 colorectal cancer patients (median age 58.61±1.12 years) included in the study, all of whom underwent laparoscopic-assisted colectomy. Patients with severe cardiac and pulmonary dysfunction, insufficient bowel preparation, anaemia and diabetes were excluded.
Of the patients, those who received the wound protector (n=57) had significantly shorter postoperative hospital stay than those who did not receive the protector (n=52; 8.73±0.54 vs 7.47±0.24 days; p=0.03). The two groups were comparable in terms of operative time (p=0.37), blood loss (p=0.43) and postoperative exhaust time (p=0.15).
Wound infection rates were significantly lower in patients who received the wound protector than in those who did not (1.75 vs 13.46 percent; p=0.02). Adhesive intestinal obstruction (5.26 percent; n=3) and uroschesis (3.51 percent; n=2) were the most common infections in the wound protector group.
In contrast, wound infection was the most common complication in the nonwound protector group. This was followed by adhesive intestinal obstruction (5.77 percent; n=3) and uroschesis (3.85 percent; n=2). There were no significant differences between the two groups in the rates of other complications.
Surgical site infections are the most common types of complications in laparoscopic-assisted surgery and are known to play a substantial role in patient morbidity and mortality. In colorectal cancer surgery, infectious agents most often come from the skin or gastrointestinal tract.
