Small bowel obstruction caused by transmesenteric hernia in a patient with complex medical history: a case report.

This case report presents a rare instance of small bowel obstruction due to a transmesenteric hernia in a 47-year-old male with a complex medical history. The patient presented with acute abdominal pain, constipation, and urinary retention. Diagnostic laparoscopy revealed bowel ischemia, and open laparotomy confirmed a transmesenteric hernia with necrotic small bowel requiring resection. Postoperative recovery was uneventful, and the patient was discharged with follow-up plans. This case underscores the importance of considering internal abdominal hernias in the differential diagnosis of acute abdominal pain.
