title: A prospective series of out-patient endoscopic retrograde cholangiopancreatography.
abstract: OBJECTIVE
  Out-patient endoscopic retrograde cholangiopancreatography (ERCP) is widely practised but the safety of this approach has only been addressed in a limited number of prospective series mainly from specialist North American centres. Our objective was to determine prospectively the safety and admission rates of out-patient ERCPs.
  
  
  METHODS
  Patients were selected for out-patient ERCP if in relatively good health, without major risk factors for complications following ERCP and with adequate social support. Our series consisted of 136 consecutive cases of which 82 were therapeutic. SETTING AND OUTCOME MEASURES: A district general hospital in the UK, which also performs ERCPs for neighbouring health districts. Out-patient ERCP patients were followed up at 30 days using standard criteria for defining complications.
  
  
  RESULTS
  Procedures were 60 biliary sphincterotomy, 10 stone removal, nine stenting procedures, two dilatations and one pancreatic intervention. Complications were pancreatitis in seven patients (six moderate severity, one mild), cholangitis in three patients, haemorrhage in one patient. Nine patients required admission for complications, two from the endoscopy unit and seven from home; their average in-patient stay was 6 days. Seventeen patients were admitted for observation or for further management. There was one death unrelated to ERCP. Overall, 110 of 136 patients did not require inpatient care following out-patient ERCP.
  
  
  CONCLUSIONS
  Our complication rates were similar to those of other series. Out-patient ERCP for selected cases, with adequate post-discharge arrangements for advice and readmission, appears safe and would reduce healthcare costs.
