Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Low dose group

Group1. Low dose group

Autologous adipose derived stem cells(low dose group)

Intervention Type BIOLOGICAL

low dose group: 1x10e7 cells/mL At 6 weeks after first stem cell injection, fistula closing was assessed. If it is not completely closed, second injection would be applied in 2 weeks. Additional dosage would be doubled to first dosage.

High dose group

Group2. High dose group

Autologous adipose derived stem cells(high dose group)

Intervention Type BIOLOGICAL

high dose group: 2x10e7 cells/mL At 6 weeks after first stem cell injection, fistula closing was assessed. If it is not completely closed, second injection would be applied in 2 weeks. Additional dosage would be doubled to first dosage.
