Brief Summary

Gastrointestinal (GI) fistula is a complex condition with high mortality and requiring a multidisciplinary management. The aim of this study is to exploit the regenerative-tissue capacities of autologous emulsified adipose tissue-derived stromal vascular fraction (tSVFem, widely used in other medical fields - like plastic surgery -for different purposes) harvested and delivered locally by endoscopy to close the GI fistula. The proposed technique for the treatment of GI fistulas with tSVFem requires a minimal, inexpensive, easily reproducible mechanical manipulation of autologous adipose tissue without necessity of any enzymatic digestion or cell expansion.

Outcome Measures

Primary Outcomes (1)

  • Fistula healing

    Rate of healing of fistula at endoscopy and gastrografin swallow

    7 days after the injection procedure of tSVFem

Secondary Outcomes (1)

  • Incidence of treatment adverse events and complications

    During the procedure, 7 days after and at 1-2 month follow-up

Study Arms (1)

Experimental arm

EXPERIMENTAL

Patients treated by endoscopic injection of emulsified adipose tissue stromal vascular fraction

Procedure: injection of emulsified adipose tissue stromal vascular fraction

Interventions

Endoscopic injection of 10 cc of autologous microfat into the fistula (through a 6-French catheter), until it was completely filled, and a total of 1-2 cc of tSVFem (through a 22G endoscopic needle) into the submucosa of the 4 quadrants of the fistula borders, to obliterate it completely.

Experimental arm
