Subcutaneous Drain Reduces Surgical Site Infections in Abdominal Wound Closure

Patients with secondary peritonitis who received a subcutaneous drain post-laparotomy had a significantly lower incidence of incisional surgical site infections (20% vs. 68%) and shorter hospital stays (8.96 days vs. 14.04 days) compared to those without the drain. Although not statistically significant, the drain also reduced the risk of wound dehiscence. Subcutaneous suction drainage is beneficial in abdominal wall closure for peritonitis cases as it effectively decreases infection rates and shortens postoperative hospital stays.
