Tube-in-tube endoscopic vacuum therapy for treatment of colorectal anastomotic leaks: A low-cost, patient-friendly, feasible and efficient technical modification of sponge-based endoscopic vacuum therapy.

Background And Aims: Colorectal endoscopic vacuum therapy (CR EVT) is usually performed using sponges passed through the anus. It may be associated with patient discomfort and displacement of the aspiration tube.

Methods: With the tube-in-tube endoscopic vacuum therapy modification (CR TT-EVT), it is possible to position the aspiration tube in the pelvic cavity through the abdominal wall.

Tube-in-tube endoscopic vacuum therapy for the closure of upper gastrointestinal fistulas, leaks, and perforations.

BACKGROUND : Although endoscopic vacuum therapy (EVT) has been successfully used to treat postoperative upper gastrointestinal (UGI) wall defects, its use demands special materials and several endoscopic treatment sessions. Herein, we propose a technical modification of EVT using a double tube (tube-in-tube drain) without polyurethane sponges for the drainage element. The tube-in-tube drainage device enables irrigation and application of suction.
