Case Discussion

Overall urgent CT abdomen and pelvis showed the complication of incarcerated hernia where the herniated small bowel loops through the incision became perforated due to closed loop obstruction resulting in abscess formation and cellulitis. The presence of large degree of subcutaneous gas raise suspicion of necrotising fasciitis.

Emergency laparotomy of small bowel resection, primary anastomosis and wound debridement performed.
Intraoperative findings: 10x10cm hernia defect, content was big clump of distal ileum with multiple sites of perforation, 150cm from duodenal jejunal junction, 50cm from terminal ileum. Faecal contamination extraperitoneally and unhealthy anterior abdominal wall.
