An uncommon cause of intestinal obstruction is an abdominal cocoon, also known as sclerosing encapsulating peritonitis (SEP). We present the case of a 24-year-old female peritoneal dialysis patient who presented with a picture of complete intestinal obstruction. After reviewing the patient\'s medical history and acquiring relevant laboratory and imaging data, the decision was made to proceed with surgery. Intraoperatively, however, she had a picture of sclerosing peritonitis. The decision was to terminate the surgery and to take a conservative approach, including total parenteral nutrition. Her condition improved, obstruction was resolved, and she was discharged home in good clinical condition. Sclerosing peritonitis should be considered a possible etiology that can be managed conservatively in any peritoneal dialysis patient with intestinal obstruction.

BACKGROUND: Sclerosing encapsulating peritonitis (SEP), commonly known as abdominal cocoon syndrome (ACS), is considered one of the rare causes of bowel obstruction [1].
METHODS: In this article, we report the case of a 20-year-old male patient with a 6-month history of recurrent colicky right-sided upper abdominal pain accompanied by nausea, vomiting and bloating, which gradually increased in severity and frequency. The contrast-enhanced abdominal computed tomography suggested a small bowel obstruction with a differential diagnosis of SEP. Later exploratory laparotomy and histopathological examination confirmed the diagnosis of ACS. Intraoperative adhesiolysis was performed and the patient\'s symptoms resolved.
CONCLUSIONS: This syndrome is characterised by the formation of a fibrous-collagenous membrane that partially or completely engulfs the small intestine, less commonly the colon and other abdominal organs. SEP is most commonly associated with long-term peritoneal dialysis, although drugs, peritoneal infection and systemic inflammatory disorders have been implicated. Patients often present with symptoms of partial bowel obstruction, which is difficult to diagnose before laparotomy. Of the available investigations, contrast-enhanced CT of the abdomen is the most sensitive, showing a fibrous sac-like membrane covering the intestinal loops and the fluid collection. Definitive treatment includes excision and adhesiolysis.
CONCLUSIONS: This article presents a rare case and focuses on the management of this pathology with a review of the literature.

BACKGROUND: Sclerosing peritonitis (SP), also known as abdominal cocoon, is a and potentially serious condition characterised by the fibrous encapsulation of the small intestine within the peritoneal cavity.
METHODS: In this report, we detail the case of a 67-year-old male with SP who initially presented with symptoms of constipation, vomiting, and abdominal pain. Despite a previous computed tomography (CT) scan revealing ileal thickening, the accurate diagnosis remained elusive until exploratory laparotomy. The patient underwent successful excision of the thick fibro-collagenous membrane, and histopathological examination revealed fibro-collagenous tissue with mild chronic inflammation.
CONCLUSIONS: SP can be classified into primary (idiopathic) and secondary forms. Primary SP, also referred to as cocoon abdomen, is more common in young females from tropical regions, while secondary SP is associated with peritoneal dialysis and other causative factors. Diagnosing SP presents challenges, as clinical symptoms may mimic those of other conditions. Imaging studies, especially CT scans, play a crucial role in the diagnostic process, yet the rarity of SP often leads to misdiagnosis. Although there is no consensus on treatment options, surgical intervention is generally recommended for symptomatic cases, involving excision of the cocoon and adhesiolysis. Conservative management may be considered for asymptomatic cases. The mortality rate for SP is high, emphasizing the importance of early diagnosis and intervention.
CONCLUSIONS: Primary sclerosing encapsulating peritonitis is a and complex, primarily affecting young individuals. Maintaining a high index of suspicion is crucial for an accurate diagnosis, and surgical intervention remains the primary treatment for symptomatic cases. The prognosis is generally favourable with timely and appropriate management.

UNASSIGNED: Idiopathic Sclerosing Encapsulating Peritonitis (ISEP) is an uncommon condition of intestinal bowel obstruction due to encapsulation of the abdominal organs in a thick fibro-collagenous membrane. The case presented here describes the emergency acute presentation of septic peritonitis discovered intraoperatively upon laparotomy.
METHODS: A middle-aged woman was admitted to the emergency department and presented with generalized colicky abdominal pain associated with repetitive vomiting, abdominal distention, and absolute constipation. A digital rectal examination revealed an empty rectum and a bilious output was observed in the nasogastric tube. Abdominal X-Ray demonstrated multiple air-fluid levels with no air under the diaphragm. The patient was treated with fluid therapy and antibiotics intravenously (IV).
UNASSIGNED: The clinical impression of acute-on-chronic intestinal obstruction with peritonitis and the possibility of bowel strangulation was made. Emergency exploratory laparotomy revealed viable bowel loops encased in thickened fibrous capsules covering the entire abdominal viscera establishing the existence of ISEP. The fibrous capsule layer was excised out in small pieces from all the abdominal organs excluding stomach through extensive adhesiolysis without loop resection.
CONCLUSIONS: The emergency presentation of acute peritonitis observed in this study could only be identified through diagnostic laparoscopy and differential radiological imaging techniques. Further, better reporting of such rare cases may help clinicians understand the different clinical features that could indicate the occurrence of ISEP.

BACKGROUND: Sclerosing encapsulating peritonitis is a rare condition with a typical macroscopic appearance, with fibrocollagenous membrane enclosing loops of the small intestine, causing intestinal obstruction. Unexplained recurrent abdominal pain, obstruction, and a large array of other possible clinical signs and symptoms make sclerosing encapsulating peritonitis a diagnostic challenge.
METHODS: A 48-year-old man of Persian ethnicity was admitted multiple times to the emergency surgery department due to recurrent sudden abdominal pain and chronic obstruction without significant findings in medical history or clinical evaluation. Computed tomography was positive for proximal jejunal dilatation and duodenojejunal flexure stenosis due to internal mesenteric hernia. Exploratory laparoscopy, followed by laparotomy, confirmed thick membrane-like fibrous tissue with complete small intestinal loop envelopment. Extensive membrane excision and adhesiolysis was performed, but no mesenteric herniation was found. Early postoperative paralytic ileus with introduction of low-dose steroid therapy, based on histopathological and immunological results, confirming type III sclerosing encapsulating peritonitis, was completely resolved.
CONCLUSIONS: Sclerosing encapsulating peritonitis is a rare and difficult-to-diagnose condition, further divided into primary and secondary sclerosing encapsulating peritonitis, on the basis of underlying etiology, dictating treatment modality and prognosis. Intraoperative diagnosis and surgical treatment are mandatory, besides a wide variety of abdominal computed tomography scans, inconclusive results, and clinical presentations. There are so far no known specific markers for the diagnosis of sclerosing encapsulating peritonitis.

Sclerosing encapsulating peritonitis (SEP), also referred to as abdominal cocoon syndrome, is a rare cause of bowel obstruction characterized by a thickened fibrous peritoneum that encapsulates the intestines. The exact etiology is idiopathic but may be associated with long-term peritoneal dialysis (PD). In the absence of risk factors for adhesive disease, preoperative diagnosis can be difficult and may require operative intervention or advanced imaging to diagnose. Thus, the inclusion of SEP in the differential diagnosis for bowel obstruction is essential for early detection. Existing literature is focused on renal disease as an origin, but it can be multifactorial. Here, we discuss a case of sclerosing encapsulating peritonitis in a patient without known risk factors.

We describe the first French patient treated for sclerosing peritonitis syndrome associated with lutheinized thecomas. At 42 years old, she had respiratory distress with increased abdominal volume. Physical examination revealed ascites, pleural effusions, and two mobile latero-uterine masses. Radiological examinations revealed bilateral ovarian masses of 10 cm. Bilateral adnexectomy was performed by laparotomy. Histological analysis concluded that there were benign luteinized thecomas. Until the 36th postoperative day, the general condition of the patient deteriorated to become critical. A second surgical procedure was attempted revealing sclerosing fibrosis preventing access to the peritoneal cavity. Subsequently, a medical treatment combining parenteral nutrition, high intravenous doses of corticosteroids, antiestrogens, colchicine and sandostatin was administered and effective allowing continuity recovery 15 months later. The clinical outcomes has been favorable at 24 month later.

BACKGROUND: Sclerosing peritonitis or abdominal cocoon syndrome is characterized by small bowel loops completely encapsulated by a fibrocollagenous membrane in the center of the abdomen. Although cocooning of the abdomen is mostly seen in patients on peritoneal dialysis, it can occur de novo; it very rarely manifests as complete mechanical bowel obstruction.
METHODS: A 46-year-old Asian man presented with complete mechanical bowel obstruction. He had previous attacks of partial bowel obstruction during the past 6 to 8 months, which was misdiagnosed as abdominal tuberculosis because tuberculosis is very prevalent in the region in which he lives. He took anti-tuberculosis therapy for 3 months but this did not result in resolution of his symptoms. This time he had diagnostic laparoscopy followed by laparotomy in which a fibrocollagenous membrane, resulting in entrapment of his bowel, was excised and his entire small bowel was freed. Postoperatively he again had a mild episode of partial bowel obstruction but this was relieved with a short course of steroids.
CONCLUSIONS: Sclerosing peritonitis is a rare benign etiology of complete mechanical bowel obstruction. Patients might have suffered recurrent attacks of partial bowel obstruction in the past that were falsely managed on lines of other conditions such as tuberculosis, especially in endemic areas like Pakistan or India.
CONCLUSIONS: Sclerosing peritonitis is a rare benign diagnosis which can manifest as complete bowel obstruction and a high index of suspicion is required to diagnose it. Contrast-enhanced computed tomography of the abdomen is a useful radiological tool to aid in preoperative diagnosis. Diagnostic laparoscopy is usually confirmatory. Peritoneal sac excision and adhesiolysis is the treatment and a short course of steroids in relapsing symptoms.

OBJECTIVE: To describe the most characteristic imaging findings for sclerosing encapsulating peritonitis, with an emphasis on the computed tomography findings.
CONCLUSIONS: The incidence of sclerosing encapsulating peritonitis is low. The pathophysiology of this condition is unclear. Two types are recognized: idiopathic and secondary; the secondary type is generally a complication of peritoneal dialysis. Its nonspecific clinical presentation and the absence of blood markers mean that sclerosing encapsulating peritonitis is usually diagnosed late. Thus, it is important to know the imaging signs; these include thickening and calcification of the peritoneum and dilation of bowel loops with thickening and calcification of bowel walls, whether in isolation or in association with loculated ascites. Although ultrasonography allows the complexity of the collections to be evaluated, computed tomography is the most useful technique for the general assessment of the signs mentioned above.

Mesenteric panniculitis is an uncommon pathology, of poorly understood etiology, characterized by progressive inflammation and fibrosis of the small bowel mesentery. This disease has been reported usually after other abdominal surgeries. We present two cases of young male patients who underwent laparoscopic sleeve gastrectomy and developed abdominal symptoms within 45-60 days of surgery. Both were investigated for known post-bariatric complications. While first patient presented (5 months later) at an irreversible stage and died within 8-9 months of primary surgery, in second patient, the disease process could be reversed through early intervention, diagnosis, treatment, and compliance. Mesenteric panniculitis is a rapidly progressive entity, which can be adequately treated by early identification and long-term immune-suppressive therapy.
