Abstract

Background and study aims A percutaneous intragastric trocar (PIT) enables intraluminal use of laparoscopic tools and helps overcome traditional limitations of endoscopy. The aim of this study was to determine the efficacy of using a PIT to perform an anti-reflux stapling procedure.

Materials and methods Trocars were placed in four animals and an articulating stapler was used to perform fundoplication under endoscopic guidance. Animals were monitored for 14 days post-procedure. Functional lumen imaging of the esophagogastric junction (EGJ) was performed at baseline, immediately post-intervention, and at 14 days.

Results The procedure was successful in all animals who survived to day 14 without distress or significant adverse events. Baseline EGJ distensibility was 5.0 ± 1.2 mm2/mmHg, 2.7 ± 0.7 mm2/mmHg post-procedurally, and 3.0 ± 0.8mm2/mmHg on day 14. Average change in distensibility pre- and post-procedure was –2.3 ± 1.8 mm2/mmHg (95 % confidence interval [CI] –0.5 to 5.1, P = 0.08) while change in pre- and day 14 distensibility was –2.0 ± 1.4 mm2/mmHg (95 % CI –0.1 to 4.2, P = 0.06).

Conclusions An intragastric trocar allows for use of large-diameter laparoscopic instruments to safely and effectively perform endoluminal fundoplication with anti-reflux properties that persist for at least 14 days.
