About this study
Official title: Closure of Fistulas and Perforations Endoscopically to Avoid Laparoscopic or Open Surgery
Background: T-shaped tissue anchors have promise to close incisions and perforations of the intestines securely. The closure of perforations, gastro-gastric, or intestinal fistulas usually requires invasive open or laparoscopic surgery under general anesthesia and can be complex surgeries due to their reoperative or inflammatory nature.
Objective: The proposed use of full thickness tissue anchors adds a new surgical aspect to the endoscopic treatment of fistulas and perforations by offering a robust suture like closure of defects. Instead of a 20 cm abdominal incision or 3 or 4 one centimeter incisions with the related postoperative morbidity an endoscopic technique is used which requires no postoperative limitation of activities.

Methods: In this study the investigators propose to use an endoscopic technique that eliminates the need for open or laparoscopic surgery and provides a more robust endoscopic repair than is possible with traditional endoscopic tools. Patients who are scheduled to undergo surgery for intestinal fistulas will be screened for study eligibility. Patients who are scheduled to undergo complex polypectomy, or submucosal dissection will be screened for study eligibility and informed about all possible therapies in case of an iatrogenic perforation (open - laparoscopic surgery, endoscopic clipping, endoscopic closure with tissue anchors). A commercially available flexible endoscope will be inserted through the mouth and the fistula or perforation will be closed using the Tissue Approximation System (Ethicon Endo Surgery, Cincinnati, OH).
The investigators will initially evaluate the potential benefit, risks and impact on the patient's quality of life of this modified surgical technique in 5 patients.
Expected results: The potential advantages to the patients entered into this study result from the avoidance of open or laparoscopic surgery with the related risks (bleeding, injury of organs, post operative wound infection, hernia), shorter hospital stay, reduced postoperative pain, earlier return to work, and cosmetic advantage.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
gastro-gastric fistula closureProcedure or surgery
Also called Tissue Apposition System, TAS, 510(k) approval # K070151
The mucosa surrounding the orifice of the fistula will be ablated using standard endoscopic techniques. Remnants of mucosa will be treated with argon-plasma coagulation. The mucosa free orifice of the fistula will be closed using the Tissue Apposition System. Tissue anchors with attached threads will be deployed through the intestinal wall full thickness using delivery needles through the working channel of the endoscope. After two anchors are deployed on both sides of the fistulas' orifice a knotting element will be cinched down to approximate the two sides of the fistulas' orifice. The procedure will be repeated until the fistulas' orifice is securely closed.
What is being measured
The primary outcome is the main question the study is designed to answer.
fistula or perforation closure possible; yes or no
Measured: day of surgery
Secondary outcomes (2)
fistula stays closed after 6 months
Measured: 6 months
quality of life comparison, pre-op and after 6 months post-op
Measured: 6 months

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
fistula or perforation closure possible; yes or no (time frame: day of surgery). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00835458, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Feb 2009; AzTrials last refreshed its copy on 8 Nov 2026.
