Mesenteric venous infarction in acute pancreatitis
1Department of Surgery, Emory University, Atlanta, GA 30309.
Summary
Segmental intestinal necrosis, a rare acute pancreatitis complication, can result from mesenteric venous infarction, not just arterial issues. This finding expands understanding of gastrointestinal complications in pancreatitis patients.
Area of Science:
- Gastroenterology
- Pathology
- Surgical Complications
Background:
- Segmental intestinal necrosis is a rare but serious complication of acute pancreatitis.
- The established understanding attributes this necrosis primarily to arterial thrombosis.
Observation:
- An unusual case of segmental small intestinal infarction associated with pancreatitis was observed.
- The clinical, gross, and microscopic features of the patient's condition pointed towards mesenteric venous infarction.
Findings:
- Literature review identified three prior cases of small intestinal infarction in pancreatitis patients with similar findings.
- Mesenteric venous infarction of the colon has also been documented in association with acute pancreatitis.
Implications:
- Mesenteric venous infarction is identified as an additional cause of intestinal necrosis in acute pancreatitis.
- This may stem from pancreatitis-induced alterations in blood clotting mechanisms.
