title: Ileosigmoid knotting in patients under 25 years of age: A report of two cases.
abstract: BACKGROUND
  Ileosigmoid knotting is a rare cause of acute abdomen with high morbidity and mortality. Its diagnosis is infrequently made before surgery because of its varying ways of presentation and rarity.
  
  
  METHODS
  The first was a 21-year-old male who presented with a history of sudden generalized abdominal pain and progressive abdominal distension. He was pale and severely dehydrated. His extremities were cold and clammy. His pulse rate was 110 per minute and blood pressure was 90/50mmHg. The second case was 20-year-old male who presented with similar symptoms as above. He was not pale but mildly dehydrated. His pulse rate was 92 per minute and blood pressure 110/70mmHg. Both patients were resuscitated and had exploratory laparotomy a few hours after presentation. The first patient was found to have ileosigmoid knotting with gangrenous sigmoid colon and terminal ileum. He had Hartmann's procedure and right hemicolectomy with ileo-transverse anastomosis. The second patient was found to have ileosigmoid knotting with viable loops of bowel. He had careful detorsion, sigmoidectomy with primary anastomosis. Both patients' have good outcome.
  
  
  CONCLUSIONS
  This is to report two cases of ileosigmoid knotting in two male patients aged 21 and 20 years, respectively, with the hope of increasing awareness.
  
  
  CONCLUSIONS
  Ileosigmoid knotting though more common in fourth or fifth decade of life, can also occur in the 2nd decade. Early diagnosis, careful resuscitation and skilful surgical intervention will improve outcome.
