title: Adult intussusception: is associated bowel gangrene common?
abstract: BACKGROUND
  Adult intussusception is a rare clinical entity in contrast to pediatric intussusception. Varied and non-specific clinical features, delayed presentation, and lack of awareness among attending surgeons to consider it as differential diagnosis complicates the clinical course of the disease.
  
  
  METHODS
  A retrospective study was conducted in a tertiary care teaching hospital in north India. Nine adult patients who presented with intussusception over a period of six years were analyzed. Their clinical profile, management and underlying pathology were studied.
  
  
  RESULTS
  Five out of nine patients had acute presentation while remaining four presented with subacute/chronic symptoms. Median duration of presentation was 8 days (range 2-180 days). Clinical diagnosis of intussusception was considered in only one patient. Ultrasonography clinched the diagnosis in all four patients who presented with subacute/chronic symptoms. Ileo-ileal intussusception was present in five patients, with one having associated jejuno-jejunal intussusception. Other four patients had ileo-colic intussusception. Seven of the 9 patients (77%) were found to have associated bowel gangrene. Resection of the bowel segment having intussusception was done in all patients. Five patients had associated benign intestinal pathology while idiopathic intussusception was present in four patients.
  
  
  CONCLUSIONS
  The patients presented in the series are distinct from cases reported earlier in literature in term of late presentation, manifesting as acute intestinal obstruction, high frequency of associated intestinal gangrene, and absence of associated intestinal malignancy. Patients presenting with features of intestinal obstruction and abdominal lump should be subjected to urgent imaging studies to examine the possibility of intussusception. The high frequency of bowel gangrene encountered in patients of adult intussusception mandates prompt surgical intervention soon after diagnosis.
