High jejunal perforation complicating tuberculous abdominal cocoon: a rare presentation in immune-competent male patient

Gastrointestinal Tuberculosis

Gastrointestinal tuberculosis (TB) is a fascinating disease which can be observed both in the clinical context of active pulmonary disease and as a primary infection with no pulmonary involvement. It represents a significant clinical challenge because of the resurgence of TB as well as the diagnostic challenges it poses. A high clinical suspicion remains the most powerful tool in an era of medicine when reliance on diagnostic technology increases. Antimicrobial therapy is the mainstay of therapy, but surgical and endoscopic interventions are frequently required for intestinal TB. Gastrointestinal TB is truly the "great mimic" and continues to require the astute clinical acumen of skillful clinicians to diagnose and treat.

Role of conservative management in tubercular abdominal cocoon: a case series

BACKGROUND

Sclerosing encapsulating peritonitis (Abdominal cocoon) is an uncommon cause of intestinal obstruction and tuberculosis is an important etiology. Appropriate management of this entity is still uncertain.

METHODS

We did a retrospective analysis of patients with abdominal cocoon who were seen over a two year period at a tertiary care center in North India. We included patients with tubercular abdominal cocoon (TAC) who were managed primarily with antitubercular therapy in the present report. The diagnosis of TAC was made using combination of criteria (radiological or surgical findings of cocoon with evidence of tuberculosis in form of microbiological, histological or biochemical evidence). The clinical presentation, outcome and need for surgery for these patients were retrieved from the records of these cases maintained in a database.

RESULTS

Of 18 patients with abdominal cocoon, 15 patients had underlying tuberculosis. The median age was 28 years (interquartile range 24) and 12 (80%) were males. Three patients had confirmed tuberculosis on basis of microbiological evidence. All had abdominal pain for 1-9 months, and 11 had intestinal obstruction. Twelve patients had positive Mantoux test, none had HIV. Pulmonary tuberculosis was noted in four patients, pleural in five, splenic and intestinal in two each, hepatic and mediastinal lymph-nodal in one each. Thirteen patients were started on usual 4-drug anti-tubercular therapy (ATT) while two cirrhotics needed modified ATT. Three patients were on steroids with ATT and all three improved. One patient was lost to follow up. Of the rest 14 patients, 2 underwent surgery, 1 at initial presentation while another after 4 months of ATT. Overall five patients developed intestinal obstruction while on ATT, one needed surgery and one died of liver failure while others improved with conservative means.

CONCLUSION

TAC can be managed conservatively in a subset of patients.

Coexistence of abdominal cocoon, intestinal perforation and incarcerated Meckel’s diverticulum in an inguinal hernia: A troublesome condition

Sclerosing encapsulating peritonitis (SEP) is a rare disease entity, in which the small intestine becomes encased and mechanically obstructed by a dense, fibrotic membrane. The disorder is characterized as either primary (idiopathic) or secondary to other causes. The idiopathic cases of SEP, which lack any identifiable etiology according to clinical, radiological and histopathological findings, are also reported under the designation of abdominal cocoon syndrome. The most frequent presenting symptoms of all SEP cases are nausea, vomiting, abdominal distention and inability to defecate, all of which are associated with the underlying intestinal obstruction. Persistent untreated SEP may advance to intestinal perforation, representing a life-threatening condition. However, preoperative diagnosis remains a particular clinical challenge, and most diagnoses are confirmed only when the typical fibrous membrane encasing the small intestine is discovered by laparotomy. Here, we report the clinical presentation of an 87-year-old male with signs of intestinal obstruction and the ultimate diagnosis of concurrent abdominal cocoon, right incarcerated Meckel’s diverticulum, and gastrointestinal perforation in laparotomy.

Idiopathic sclerosing encapsulating peritonitis: Abdominal cocoon

Abdominal cocoon, the idiopathic form of sclerosing encapsulating peritonitis, is a rare condition of unknown etiology that results in an intestinal obstruction due to total or partial encapsulation of the small bowel by a fibrocollagenous membrane. Preoperative diagnosis requires a high index of clinical suspicion. The early clinical features are nonspecific, are often not recognized and it is difficult to make a definite pre-operative diagnosis. Clinical suspicion may be generated by the recurrent episodes of small intestinal obstruction combined with relevant imaging findings and lack of other plausible etiologies. The radiological diagnosis of abdominal cocoon may now be confidently made on computed tomography scan. Surgery is important in the management of this disease. Careful dissection and excision of the thick sac with the release of the small intestine leads to complete recovery in the vast majority of cases.

A problem encapsulated - role of CT

Sclerosing encapsulating peritonitis (SEP) is a rare but serious complication of abdominal surgery, recurrent peritonitis, and continuous ambulatory peritoneal dialysis with a high morbidity and mortality. The etiology of this condition is largely unknown. Diagnosis is usually established at laparotomy in patients with recurrent attacks of non-strangulating, small bowel obstruction. We report a case of a patient who presented with intestinal obstruction and who showed typical CT findings of SEP which was diagnosed pre-operatively on a CT scan and confirmed at surgery. The interest of this case lies in its rarity and difficult pre-operative diagnosis.
