Colonic injury

What is colon injury Colon injury is a relatively common hollow organ injury caused by blunt abdominal trauma and penetrating injury, and can also result from iatrogenic injury such as perforation of the colon due to barium enema, colonoscopic polypectomy with electrocautery resection. Because the colon contains a large number of bacteria, peritonitis is severe, systemic toxic symptoms are pronounced, and it often threatens life. A portion of the colon is located retroperitoneally; when injured, peritonitis may not be obvious, making it easy to miss the diagnosis. Abdominal injury often involves multiple organs and multiple segments of intestinal injury, with obvious peritonitis, which can mask colon injury and lead to misdiagnosis or missed diagnosis, and attention should be paid to this. The incidence of colon injury is lower than that of small intestine injury, but because the colonic contents have fewer liquid components and a higher bacterial content, peritonitis appears later but is more severe. The vast majority are penetrating injuries, with closed injuries being rare, and most are accompanied by injury to other organs. The prognosis depends on the location of the colon injury, the degree of injury, the extent, and the degree of peritoneal contamination, and is closely related to timely rescue and appropriate management. One-stage repair or anastomosis has a higher rate of complications such as intestinal fistula and residual intra-abdominal infection.
