  "abstract": "Introduction:: Idiopathic sclerosing encapsulating peritonitis (SEP), or abdominal cocoon syndrome, is a rare cause of chronic small bowel obstruction characterized by encasement of the small intestine within a fibrocollagenous membrane. Its nonspecific presentation and variable imaging findings frequently make preoperative diagnosis difficult.\n\nCase presentation:: A 39-year-old man presented with several months of progressive intolerance to solid food, recurrent vomiting, abdominal pain, constipation, and weight loss. He had no history of abdominal surgery, tuberculosis, inflammatory bowel disease, peritoneal dialysis, or recurrent peritonitis. Laboratory evaluation showed mild normocytic anemia and hypokalemia. Upper gastrointestinal endoscopy demonstrated mild chronic Helicobacter pylori gastritis without mechanical obstruction. A repeat contrast-enhanced computed tomography scan showed diffuse gastric and small bowel dilatation with delayed transit but no definite transition point or visible encapsulating membrane. Because symptoms persisted despite conservative management, diagnostic laparoscopy was performed and was converted to laparotomy because of extensive adhesions. The entire small intestine was enclosed within a dense fibrocollagenous membrane. Complete membrane excision and adhesiolysis were performed without bowel resection. Histopathology confirmed SEP and showed no evidence of tuberculosis or malignancy. Chronic opium use may have contributed to gastrointestinal dysmotility but could not explain the structural encapsulation. The patient remained symptom-free for 6 months of follow-up.\n\nConclusion:: Idiopathic SEP should be considered in patients with chronic or recurrent obstructive symptoms despite nondiagnostic imaging. Definitive diagnosis may require operative exploration and histopathological examination.",
