Bleeding ileal schwannoma resulting in severe anemia requiring massive blood transfusion: A rare case report.

Introduction: Melena is a common symptom of schwannoma of the small intestine, a rare type of tumor. Even more rare is schwannoma of the small intestine that requires a massive blood transfusion due to hemorrhage. Herein, we report such a case successfully treated with surgical resection.

Time limit to rescue intestine with viability at risk caused by blood flow disruption in patients presenting with acute abdomen.

Purpose: Early management is crucial for acute intestinal blood flow disorders; however, no published study has identified criteria for the time limit for blood flow resumption. This study specifically examines the time factors for avoiding intestinal resection.

Methods: The subjects of this retrospective cohort study were 125 consecutive patients who underwent emergency surgery for a confirmed diagnosis of intestinal strangulation (n = 86), incarceration (n = 27), or volvulus (n = 12), between January 2015 and March 2021.
