Diverticular Wall Weakening in Complicated Diverticulitis

A weak point in the colon wall balloons outward under pressure.

  • Sigmoid: Common site (Short placeholder note)
  • Muscularis: Wall layer affected (Short placeholder note)
  • 50+: Typical age (Short placeholder note)
  • Low fiber: Risk driver (Short placeholder note)

Wall weakening mechanism

Free Perforation and Escape of Intraluminal Air

Full-thickness rupture lets bowel gas and contents escape freely.

  • Acute: Onset (Short placeholder note)
  • Diffuse: Pain pattern (Short placeholder note)
  • Tachycardia: Vitals (Short placeholder note)
  • III–IV: Hinchey stage (Short placeholder note)

CT Detection of Extraluminal Free Air

CT reveals pockets of free air confirming perforation.

  • CT abd/pelvis: Modality (Short placeholder note)
  • Free air: Key sign (Short placeholder note)
  • High: Sensitivity (Short placeholder note)
  • IV + oral: Contrast (Short placeholder note)

Imaging findings

Fecal and Purulent Peritonitis Development

Spilled bowel contents spread infection across the peritoneum.

  • Fecal/pus: Contamination (Short placeholder note)
  • Sepsis: Complication (Short placeholder note)
  • Elevated: Mortality risk (Short placeholder note)
  • Urgent: Response needed (Short placeholder note)

Peritonitis spread

Emergency Hartmann's Procedure and Colostomy Formation

Diseased segment is resected and an end colostomy is formed.

  • Hartmann's: Procedure (Short placeholder note)
  • End colostomy: Stoma type (Short placeholder note)
  • Closed: Rectal stump (Short placeholder note)
  • Later stage: Reversal (Short placeholder note)
