Predictors of severity in ischaemic colitis

Area of Science:

• Gastroenterology
• Colorectal Surgery
• Pathology

Background:

• Ischaemic colitis (IC) results from inadequate colonic perfusion, potentially leading to severe inflammation and life-threatening complications.
• Accurate diagnosis is crucial, as IC can be misdiagnosed and requires exclusion of other conditions like inflammatory bowel disease and infections.

Purpose of the Study:

• To identify patient characteristics that predict disease severity in biopsy-confirmed ischaemic colitis.
• To differentiate factors associated with conservative management versus surgical intervention or mortality.

Main Methods:

• Retrospective analysis of consecutive patients with biopsy-confirmed IC over a 5-year period.
• Strict inclusion criteria were applied to ensure diagnostic accuracy, excluding cases due to vascular procedures, tumors, IBD, or infections.
• Patients were categorized into severe (requiring surgery or mortality) and non-severe groups based on outcomes.

Main Results:

• Thirty-two patients met the inclusion criteria; 23 were managed medically (4.3% mortality) and 9 surgically (22.2% mortality).
• Significant predictors of severe IC included right-sided location (p=0.0002), abdominal guarding (p=0.001), absence of rectal bleeding (p=0.005), and history of chronic constipation (p=0.02).

Conclusions:

• Conservative management is effective for the majority of IC patients.
• Right-sided IC, guarding, lack of rectal bleeding, and chronic constipation are significant indicators of severe ischaemic colitis, aiding in risk stratification and treatment planning.
