Data may inform device decisions
“This was an important study conducted to evaluate the different scope devices for defect closure,” said Anita Afzali, MD, MPH, AGAF, a gastroenterologist specializing in inflammatory bowel disease and is executive vice chair of internal medicine at the University of Cincinnati.
“These devices have an impact on risk for delayed bleeding and perforation,” said Dr. Afzali, who served as moderator of the session in which the study was presented.
“With different items now available for defect closure, this randomized controlled study provides guidance on which TTS approximation device should be considered, and help determine effectiveness of defect closure,” she said.
“The results of this randomized controlled trial were very informative,” Dr. Afzali said. The data indicated that both DAT and TSD achieved similar rates of tissue approximation and complete closure, but “what was interesting was that one TSD is equivalent to two DAT for tissue approximation. Further, tissue approximation was three times faster with DAT, and complete closure costs were lower in the DAT-treated group.”
In clinical practice, “the study was able to help identify scenarios, such as resection beds involving greater than 50% circumference or defects located in the duodenum, where TSD is preferred over DAT for defect closure. These suggested scenarios are also important for clinical practice and device considerations,” Dr. Afzali said. “Additional studies with use of both devices, TSD and DAT simultaneously on a defect site may be needed to further assist endoscopists in defect management.”
The study was limited by the small size and use of data from a single center.
However, “based on our interim data, both devices are equally effective for tissue approximation of large endoscopic defects,” and facilitate complete defect closure, Dr. Jawaid said.
Ultimately, “both devices have a role,” with DAT being faster and likely more cost effective, while TSD is likely preferable for defects in the duodenum and those with a circumference greater than 50%, he said.
The study received no outside funding. Dr. Jawaid disclosed a consultancy with Boston Scientific, ConMed, CREO Speedboat, and DiLumen. Dr. Afzali disclosed numerous relationships with pharma including having served as an advisor/consultant for AbbVie, Bristol Myers Squibb/Celgene, Eli Lilly, and Gilead, among others.
