A 42 year-old male presented with abdominal pain and multiple episodes of vomiting since last month. He had several such episodes in the past with spontaneous relief. The abdomen was doughy on palpation with lumpish feel in supraumbilical region. X-ray abdomen was normal. CECT abdomen revealed clumping of small bowel surrounded by thickened membrane (Figure 1). At laparotomy the entire small bowel was encased in a cocoon-like fibrous membrane (Figure 2). Extensive adhesiolysis and excision of membrane was done. Histopathology showed lymphocytic inflammation with few gaint cells with the final impression being sclerosing encapsulating peritonitis.
