Isolation techniques for gastrointestinal tract defects: Two case reports

Figure 1 Endoscopic view of the fistulas of Patient 1. A: Lower fistulous tract with a channel; B: Openings of the upper fistulous tract above the anastomosis; C: Result after 10 days of therapy, with a residual cavity formed.

Figure 2 PandiCath^®. 1: Channel for inflating balloons 5 and 8; 2: Main channel for fluid infusion, passive drainage, and shunting of the proximal and distal sections of the organ; 3: Manipulation channel connected to a controlled negative pressure pump, ensuring outflow from the isolated area or administration of medications; 4: Perforation openings above the isolated area; 5 and 8: Inflatable isolation balloons positioned above and below the defect area; 6: Opening of the manipulation channel (3), located between the balloons, allowing for biological material collection; 7: Protrusions around opening 6, preventing adhesion of the mucous layer; 9: Distal opening of channel 2.
