Sclerosing encapsulating peritonitis (SEP) is a rare disorder that is characterized by encapsulation of bowel loops by thick fibrinogenous case. Most patients present with vague abdominal symptoms. It is challenging to diagnose the condition preoperatively. Surgical management is preserved for patients with small bowel obstruction with no improvement on conservative measures or for those with signs of bowel ischemia (Li et al., 2014; Habib et al. 2011). Herein, we discuss the clinical signs and symptoms, the radiological features, the surgical management, and outcome of SEP based on a patient who underwent surgery in our hospital.
