Abdominal cocoon syndrome, a rare and interesting cause of intestinal obstruction: A case report.

Key Clinical Message: Abdominal cocoon syndrome is a rare cause of bowel obstruction, with variable presentation. It needs a high index of suspicion for diagnosis. Surgical management with the release of adhesions is the preferred option for a healthy bowel. Iatrogenic bowel perforation is a possibility during bowel manipulation and the release of thick fibrous adhesions resulting in bowel resection. Abstract: Abdominal cocoon syndrome, also known as encapsulating peritoneal sclerosis, is a rare cause of intestinal obstruction in which the small intestine may be entirely or partially wrapped in a thick sac of fibrous tissue that resembles a cocoon. We present a male Ethiopian patient, 60 years of age, who had a 6-day history of symptoms of intermittent intestinal obstruction. Before his current presentation, he had a 6-month history of sporadic vomiting and periodic abdominal pain. These symptoms would go away on their own. An exploratory laparotomy was performed for the preoperative diagnosis of small intestine obstruction secondary to primary small bowel volvulus after a plain abdomen x-ray confirmed the small bowel obstruction diagnosis. But during surgery, we discovered something unexpected: a mass formed by the encasing membrane over the small bowel. En bloc resection of the mass and distal ileum with ileo-transverse anastomosis was performed. The patient was discharged after 5 days of an uneventful post-operative stay. The morbidity and mortality of this rare instance can be decreased by awareness, prompt diagnosis, and appropriate intervention. We discuss diagnostic and therapeutic challenges encountered during the management of this patient.

An Idiopathic Case of Sclerosing Encapsulating Peritonitis: A Case Report.

Sclerosing encapsulating peritonitis, also known as abdominal cocoon syndrome, is an uncommon disorder where a dense fibrous layer forms around the small intestine, causing blockage and vague abdominal complaints. Despite its infrequency, diagnosing and treating this condition is challenging due to its indistinct symptoms and the complex nature of its treatment. This report discusses a 55-year-old female with no notable medical history who experienced progressive abdominal pain and weight loss. Initial laboratory tests revealed mild normocytic anemia and raised levels of inflammatory markers. A computed tomography (CT) scan demonstrated "cocoon-like" encapsulation of the small intestines. After ruling out infectious, neoplastic, and autoimmune factors, the patient was diagnosed with idiopathic sclerosing encapsulating peritonitis. The treatment strategy began with conservative measures, including total parenteral nutrition and antibiotics, but eventually required surgical intervention due to ongoing symptoms. Postoperatively, the patient recovered well, showing significant symptom relief and weight gain at a six-month checkup. This case emphasizes the need to consider sclerosing encapsulating peritonitis when diagnosing unexplained abdominal symptoms, especially when no typical risk factors are present.

Abdominal cocoon syndrome (ACS): a case report of a Chinese male diagnosed idiopathic ACS with inborn short intestine.

Introduction and importance: Abdominal cocoon syndrome (ACS), as a rare cause of mechanical intestinal obstruction, can be divided into primary/idiopathic vs. secondary type. The primary ACS is often asymptomatic and only diagnosed in exploratory laparotomy. The major treatment of surgery can be challenging. Since the gut wall and peritoneum are densely adhered, gut perforation might occur during adhesiolysis. Thus, it is important to have an experienced surgeon to perform the surgery. Case presentation: The authors present a primary ACS case of a 50-year-old man. The patient demonstrated an unbearable upper abdominal pain upon admission. A computed tomography (CT) scan showed a severe bowel obstruction. An exploratory laparotomy was indicated, leading to the diagnosis of ACS, which was considered idiopathic after ruling out secondary factors. An adhesiolysis was performed successfully. Note that the entire intestine measured was only 2.1 m during the surgery. There was no post-surgical complication. The patient was recovered uneventfully. Clinical discussion: The aetiology of primary ACS is unknown. The incidence is comparatively low and considered equal between men and women. As a rare cause of gut obstruction, the suspicion of the diagnosis should be strengthened. Surgery including adhesiolysis and bowel resection remains the major treatment. If adhesiolysis fails, bowel resection will be inevitable. The knowledge and experience of surgeon will be tested. Conclusion: The aetiology of primary ACS should be further explored. And the differential diagnosis of bowel obstruction should cover ACS in order for the surgeon to be prepared before surgery.

Primary abdominal cocoon syndrome manifesting with Chilaiditi syndrome and intestinal obstruction: A case report.

Key Clinical Message: Abdominal cocoon syndrome and Chilaiditi syndrome are rare etiologies of bowel obstruction which have to be considered in patients with obstructive symptoms. Patients can profit from surgical management rather than non-surgical approach. Abstract: Encapsulating peritoneal sclerosis or abdominal cocoon syndrome (ACS) is an uncommon cause of intestinal obstructions associated with encapsulation of the small bowel by a fibro collagenous sac. Clinical presentations of ACS are unspecific and most patients are diagnosed intraoperatively. Moreover, Chilaiditi syndrome is another rare cause of bowel obstruction defined by interposition of colon and liver. There is no reported relation between these two conditions and surgical intervention is the suggested approach for severe bowel obstruction following them individually. We present a case with both conditions and describe our approach. A 47-year-old male presented with complaints of colic abdominal pain and distention, nausea and several attacks of bilious and nonbilious vomiting, anorexia, and constipation in the last 10 days before his admission. Laboratory data were normal and abdominal X-ray showed large dilation at the distal part of the bowel without air fluid level. The patient underwent explorative laparotomy and a mass-like lesion containing necrotic bowel and a whitish spleen accompanied by a complete anterior-rotated liver was found. The encapsulated bowel and the spleen were resected followed by the complete resolution of symptoms in the patient. The intestinal obstruction caused by ACS is mostly approached by surgery to prevent the fatal sequela of this condition.

A case report of idiopathic sclerosing encapsulating peritonitis causing an acute bowel occlusion in adult.

INTRODUCTION: 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. CASE PRESENTATION: 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. DISCUSSION: 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. CONCLUSION: 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.

Chronic constipation and acute small bowel obstruction due to small bowel encapsulation: A case report.

Key Clinical Message: Peritoneal encapsulation is most of the time asymptomatic and is found incidentally, but when symptomatic it usually presents with bowel obstruction. CT scan is a gold standard for the diagnosis of bowel encapsulation. Abstract: Congenital peritoneal encapsulation (CPE), abdominal cocoon syndrome (ACS), and sclerosing encapsulating peritonitis (SEP) are syndromes in which the small bowel is encapsulated. Small bowel encapsulation is usually asymptomatic and rarely presents with small bowel obstruction. In this article, we report a 65-year-old man who presented to our hospital with signs and symptoms of small bowel obstruction. He underwent an urgent operation, and small bowel encapsulation was diagnosed. One year after the surgery, all symptoms improved.

Coexisting of small bowel perforation and abdominal cocoon syndrome: A case report.

Abdominal cocoon syndrome (ACS) is a rare situation and has an unknown etiology. Patients are characterized by the development of intraabdominal fibrotic tissue surrounding the small intestine as a result of chronic inflammation of the peritoneum. Small bowel perforations due to foreign bodies are not frequent in clinical practice. The coexistence of these two rare situations are extremely uncommon. In this article, the radiological findings and treatment process of the patient who presented with acute abdomen syndrome findings and the association of these two rare conditions are presented.

Idiopathic Sclerosing Encapsulating Peritonitis Associated With Persistent Descending Mesocolon: A Surgical Puzzle.

During our practice as clinical surgeons, we have encountered situations in which exploratory abdominal laparotomies have yielded unexpected outcomes, despite conducting thorough and rigorous preoperative studies. A rare condition called sclerosing encapsulating peritonitis (SEP), in which a fibrocollagenous membrane encircles the intestine and other abdominal organs, surprised us in a case of an acute abdomen. Persistent descending mesocolon is another unusual condition in which the descending colon is transferred downward and to the right abdominal region because its mesocolon is unable to merge with the posterior abdominal wall. Those two different conditions are extremely rare and were never been described in a single case. We present a case of an 80-year-old male who presented in the emergency department with an acute abdomen and puzzled us.

Abdominal cocoon syndrome, a diagnostic challenge affecting the treatment. A rare case report from Somalia.

Abdominal cocoon syndrome is defined as idiopathic encapsulation of the bowel within a fibrocollagenous membrane and is considered as a rare cause of small bowel obstruction. A 15-year-old female presented complaining of right lower abdominal pain, distension and vomiting for 24 hours with previous similar attacks in the last four years. She had no another significant medical or surgical history. Computed tomography study revealed matted mildly distended bowel loops centrally with a suspicion of acute appendicitis. Next day, abdominal pain was the only clinical finding and acute appendicitis was the primary diagnosis. During surgery, most of the small bowel was found to be encapsulated within a cocoon-like fibrous membrane. The appendix was congested. Appendectomy, full resection of the membrane and dense adhesiolysis were performed. Herein, we will present the first reported case from Somalia and discuss the radiological findings affecting the management for such a rare disease.

Abdominal cocoon syndrome. A rare cause of mechanical intestinal obstruction: A case report.

INTRODUCTION AND IMPORTANCE: Abdominal Cocoon Syndrome (ACS) also known as Idiopathic. Sclerosing Peritonitis, is a rare cause of Mechanical Intestinal Obstruction. CASE PRESENTATION: We present a 59-year-old man with severe intestinal blockage symptoms for three days. Rectum had a noticeable amount of abdominal fat. To rule out the more common causes of mechanical blockage, a CT scan revealed the presence of a rare condition called Cocoon Syndrome, which necessitated exploratory laparotomy and adhesiolysis surgery. After the surgery, the patient was declared stable and was released from the hospital. CLINICAL DISCUSSION: The diagnosis of a tuberculous abdominal cocoon before surgery is a real challenge. CONCLUSION: Recognizing and understanding this entity, as well as the usual radiological findings, may help in its appropriate treatment.

Abdominal cocoon syndrome as rare cause of intestinal obstruction: A case report.

INTRODUCTION: Abdominal cocoon syndrome (ACS) is a rare complication that is hardly diagnosed before surgery. Abnormal membrane in partial or total intestine can make obstruction with generalized abdomen pain. CASE PRESENTATION: We present a case of 43-year-old man, who presented to our hospital with generalized abdominal pain, preferably hypogastric. He has recurrent nausea and vomiting with no appetite. Dilated loops were explored between pancreases and stomach that are continued to the ileum. Complete removal of the membrane performed by laparotomy. DISCUSSION: Idiopathic sclerosing encapsulating peritonitis (SEP), known as cocoon syndrome, is a rare complication with unknown cause and pathology. Obstruction is the chief compliant. Abdominal discomfort, tenderness, nausea, and intestinal distention are also presented. Previous peritoneal dialysis, intra-abdominal inflammation, previous abdominal surgery or trauma, and beta-blocker intake predispose patients to the SEP. The present case has chronic SEP type 2, as the membrane existed in the entire small intestine. CONCLUSION: Our case highlights the importance of considering ACS as a differential diagnosis for left upper quadrant abdominal pain in patients with obstructive symptoms, especially by surgeons, because it is difficult to diagnosis before surgery.

Abdominal Cocoon Syndrome: A Laparoscopic Approach.

Sclerosing encapsulating peritonitis, or abdominal cocoon syndrome (ACS), is a rare cause of intestinal obstruction in which the small bowel is encapsulated by a fibro-collagenous membrane. We present the case of a 29-year-old male who presented to us with acute intestinal obstruction. The imaging performed suggested the presence of ACS. The patient underwent laparoscopic adhesiolysis and the small bowel was released. In cases of recurrent small bowel obstruction, a high index of suspicion is required for the diagnosis of ACS. Computed tomography can be a useful imaging modality, and surgery remains the mainstay of treatment.

A Diagnostic Dilemma for Acute Abdomen: Sclerosing Encapsulating Peritonitis (Abdominal Cocoon Syndrome); A Retrospective Cohort Study.

BACKGROUND: Sclerosing encapsulating peritonitis (SEP) is a rare cause of acute abdomen and can be easily misdiagnosed. Preoperative diagnosis of the SEP can be performed with preoperative imaging studies. We aimed to evaluate the clinical features of ileus cases who were diagnosed with primary or secondary SEP in the last five years. METHODS: This retrospective cohort study evaluated the patients who were admitted with ileus or acute abdomen symptoms to the Emergency Department of Elazig Training and Research Hospital and underwent surgery by the same surgical team of General Surgery Department between January 2014 and January 2019. Patients who were diagnosed with primary or secondary SEP were included. The demographic data, clinical presentation, whether the disease was primary or secondary, the treatment options performed and mortality rates were evaluated. RESULTS: SEP was observed in 11 of the patients. Ten patients underwent surgery (90.9%), and one patient (9.1%) was treated conservatively. Of the patients, six had secondary SEP (54.5%) and five had primary SEP (45.5%). In total, five patients were female (45.5%) and six were male (54.5%). The median age of the patients was 35 years (24-69). The median age of the patients with primary disease was 48 (29-69) years, while the median age of patients with secondary disease was 34.5 (24-64) years. One patient expired in the postoperative 8th hour. CONCLUSION: SEP should be considered in the case of recurrent abdominal pain attacks, especially in patients undergoing peritoneal dialysis, and it should be known that the mortality rate is high when misdiagnosed.

Difficult to Diagnose the Cause of Intestinal Obstruction due to Abdominal Cocoon Syndrome.

Abdominal cocoon syndrome (sclerosing encapsulating peritonitis) is a rare condition associated with clinical signs of intestinal dysfunction, episodes of small bowel obstruction and sometimes a palpable abdominal mass. We present the case of a 46-year-old male patient with clinical signs of intestinal obstruction caused by primary sclerosing encapsulating peritonitis. LEARNING POINTS: Abdominal cocoon syndrome is rare condition with repeated episodes of intestinal obstruction.Radiological investigations combined with a high index of suspicion are mandatory for establishing the diagnosis.Proper and timely diagnosis can lead to successful conservative treatment.

Abdominal Cocoon or Encapsulating Peritoneal Sclerosis: A Rare Cause of Small Bowel Obstruction.

Encapsulating peritoneal sclerosis (EPS), also known as abdominal cocoon syndrome (AC) or sclerosing encapsulating peritonitis (SEP), is an uncommon condition typically presenting with features of bowel obstruction. We present the case of a 41-year-old male patient who presented to the accident and emergency department with a 7-day history of abdominal pain. Contrast CT of the abdomen and pelvis was ordered and was suggestive of small bowel obstruction involving most of the small bowel with no apparent transition point. Laparotomy showed a tough whitish fibrous membrane encasing the entire length of the small bowel. Advances in CT have made diagnosis possible before a decision on surgical intervention is made. LEARNING POINTS: Despite being a rare cause of bowel obstruction, based on the clinical presentation and CT findings, abdominal cocoon syndrome should be included in the differential diagnosis.CT of the abdomen is the investigation of choice for most cases of bowel obstruction and can be very helpful in reaching a diagnosis before operative management is undertaken.Laparotomy is the usual choice for management, but laparoscopy can be considered either to establish the diagnosis or to deal with the abdominal cocoon based on the surgeon's clinical judgement and experience.

Primary abdominal cocoon with cryptorchidism: a case report.

BACKGROUND: We report a rare case of primary abdominal cocoon with bilateral cryptorchidism. CASE PRESENTATION: The patient had a history of laparoscopic surgery for bilateral cryptorchidism 6 years earlier. He was admitted to the hospital again due to intestinal obstruction. Surgery was performed on the patient after the failure of conservative treatment. The patient was diagnosed with primary abdominal cocoon. Instead of the greater omentum, many cocoon-like tissues surrounding the bowel were seen during operation. Abdominal surgery can increase the risk of intestinal adhesion, which is one of the main causes of intestinal obstruction, especially in patients with abdominal cocoon. We hypothesize that the surgery 6 years earlier to address transabdominal bilateral cryptorchidism accelerated the patient's intestinal obstruction. CONCLUSION: This case implies that it is important for urologists to evaluate whether their patients exhibit abdominal cocoon before cryptorchidism surgery, to choose better surgical methods and reduce the risks of poor prognosis.

Mechanical intestinal obstruction following laparoscopic inguinal hernia repair in a patient with abdominal cocoon syndrome.

Abdominal cocoon syndrome (ACS) is a rare condition characterized by partial or complete encasement of small intestine by a thick fibro-collagenous membrane. A 65-year-old man presented to the surgical department with left inguinal. He underwent laparoscopic transabdominal preperitoneal inguinal hernia. When we inserted a trocar into the peritoneal cavity, the small intestine was injured and repaired immediately. We identified a fibrotic membrane covering the small intestine, which was found as ACS. Two weeks later after discharge, he presented to the emergency department with mechanical intestinal obstruction. Conservative treatment had no effect on the patient and membrane excision, adhesiolysis and small intestine resection with anastomosis were performed. Unfortunately, the patient was hospitalized for a long time with bowel leakage and discharged on postoperative day 48. The preoperative diagnosis is quite challenging and most cases are diagnosed intraoperatively. When finding the ACS during the operation, careful attention should be needed.

Sclerosing peritonitis presenting as complete mechanical bowel obstruction: a case report.

INTRODUCTION: 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. CASE PRESENTATION: 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. DISCUSSION: 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. CONCLUSION: 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.

An association between transmesenteric internal hernia and abdominal cocoon syndrome: A case report.

INTRODUCTION: Transmesenteric internal hernia is defined as the herniation of the small intestine from a mesenteric defect in the abdominal cavity, and abdominal cocoon syndrome is the partial or entire encapsulation of the small bowel like the shape of an accordion, by a fibrocollagenous membrane. PRESENTATION OF CASE: A 32-year old male patient applied with complaints of abdominal pain, nausea, and vomiting bile. Signs visualized in the abdominal computer tomography were as follows: gatto formation of the small intestinal loops and suspected of an internal hernia.In the operation, a membrane was detected encapsulating the entire intestine resembling a tube, making the intestines to appear like an accordion and an opening was present in the small intestinal mesentery. The intestine was separated from the defect, and placed in its normal anatomical position. The defect in the mesentery was closed and the encapsulating membrane was removed from small intestine. Intestinal resection was not required. DISCUSSION: Internal hernias comprise less than 1% of all intestinal obstructions, and are formed by the herniation of the intestine and mesentery into the opening of the visceral peritoneum or into the recessus. Abdominal cocoon syndrome is a disorder characterized by the partial or total encapsulation of the small intestine by a thick and fibrotic membrane. Preoperative diagnosis is very difficult and is generally diagnosed during laparotomy exploration. CONCLUSION: The association of internal herniation and abdominal cocoon syndrome is an extremely rare cause of mechanical intestinal obstruction. If not promptly diagnosed and treated, can lead to serious complications.
