Please assess the completion status of the following clinical trial:

Trial Title: Autologous Fibrin Glues for Fistulas Closure

Study Design Characteristics:
- Allocation: NON_RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE
- Phase: PHASE1
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* older than 18 years~* presence of one or more fistulas~* fistulas of low-output volume (\< 200ml/24h)~Exclusion Criteria:~* failure to meet inclusion criteria~* mental handicap~* extreme thinness~* fistulous tract length \< 2 cm~* fistulous tract diameter \> 1 cm~* entero-atmospheric fistulas~* Crohn's disease-related fistulas~* any conditions that might impede spontaneous closure of the fistula, such as complex tracts, associated abscesses, residual disease, foreign bodies or distal obstruction~* any conditions that might increase the risk of auto-transfusion, including hypertension, or diabetes; and acquired immune deficiency syndrome (AIDS)

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: 75 Years
- Healthy Volunteers: f

Study Arms:
- conservative therapy (Type: SHAM_COMPARATOR): Conservative therapy includes orrection of electrolytic disturbances, suppression of gastric/intestinal secretion with octreotide, nutritional support.
- Application of autologous PRFG (Type: ACTIVE_COMPARATOR): The application of the glues through the external opening of the fistula was controlled by the drainage tube, which was based on fistulography to assure total occlusion of the internal hole. To allow the adhesion of the fibrin glues patch, all fistulous tracts were debrided to produce a smooth surface. At the time of procedures, the two components were mixed together to yield a gelatinous substance. After the FG was instilled, any redundant glue was removed from the external openings.

Based on this trial design, predict the completion outcome and termination type (if applicable).
