Abstract
Objectives. Endoscopic submucosal dissection (ESD) is a technically difficult, hazardous, and time-consuming treatment option for superficial neoplasms of the esophagus. The aim of this pilot study was to determine the effectiveness and safety of percutaneous transgastric traction (PTT)-assisted ESD, a method that overcomes the drawbacks of conventional ESD, in a porcine model. Methods. Six domestic pigs (2530 kg) were used in the study. In each animal, two 5-cm-long esophageal areas were assigned randomly for resection by conventional ESD or PTT-assisted ESD. The PTT method was designed to offer esophageal mucosal traction directed toward the stomach. The wire was introduced into the stomach through a percutaneous transgastric cannula and was fixed on the resected esophageal mucosa. Results. Submucosal dissection in the traction group required only half the time of that in the non-traction group (mean dissection time 596.0 vs. 1127.3 s, respectively; p 0.01). At necropsy, no differences in the incidence of perforation or bleeding were found between two groups. Conclusions. The PTT method can enhance the speed of submucosal dissection for esophageal ESD to completely remove large areas of resected mucosa. ? 2012 Informa Healthcare.
