Up to date, a sure cure for Crohn's fistula does not known and the fistula recurrence rate is high. On 15 October 2008, orphan designation was granted by Korea FDA for human adipose-derived stem cell (ADIPOPLUS) for the treatment of Crohn's fistula. In this study, patients are given injection of ADIPOPLUS in fistula site and followed for 8 weeks to evaluate the safety and efficacy.

Primary Outcome Measures:
  • Efficacy: complete closure of fistula at week 8 [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  • number of patients with any adverse event [ Time Frame: Day 0, Week 8 ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Photo of target fistula [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
    taking Photo of target fistula : Day 0, week 4, 6, 8

  • number of patients with any adverse events [ Time Frame: 8 weeks ] [ Designated as safety issue: Yes ]
    Adverse reaction : day 0, Week 4, 6, 8

  • number of patients with complete closure of fistula [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
    complete closure : every visits more than 50% closure of fistula : every visits

  • Investigator's satisfaction [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
    Investigator's satisfaction : week 8
