| الوصف: | BACKGROUND: Endoscopic submucosal dissection (ESD) is widely accepted as a local treatment for gastrointestinal tract tumors. As a simplified endoscopic procedure, hybrid ESD (H-ESD) has been performed for colorectal neoplasms in recent times. However, whether H-ESD is superior to conventional ESD (C-ESD) for patients with early gastric neoplasms (EGN) remains unclear. In this trial, we will compare the treatment outcomes of H-ESD and C-ESD. We hypothesize that the procedure time for H-ESD is shorter than that for C-ESD. METHODS: This is an investigator-initiated, multi-center, prospective, randomized, open-label, parallel-group trial to be conducted beginning in August 2020 at nine institutions in Japan. We will determine if H-ESD is superior to C-ESD in terms of procedure time in patients with EGN diagnosed as macroscopically intramucosal (T1a) differentiated carcinoma ≤ 20 mm in diameter without ulcerative findings according to current Japanese gastric cancer treatment guidelines. A total of 82 patients will be recruited and randomly assigned to either the C-ESD or the H-ESD group. The primary outcome is ESD procedure time. Secondary outcomes include mucosal incision, time and speed of submucosal dissection, en bloc resection, complete resection, curability, adverse events related to the ESD procedure, extent of dissection before snaring, volume of injection solution, number and time of hemostasis, thickness of the submucosal layer in the resected specimen, and handover to another operator. The stated sample size was determined based on the primary outcome. According to a previous report comparing the procedure times of C-ESD and H-ESD, we hypothesized that H-ESD would provide a 0.2 reduction in logarithmically concerted procedure time (−37%). We estimated that a total of 82 participants were needed to reach a power of 80% for a t-test with a significance level of 0.05 and considering a 10% dropout. DISCUSSION: This trial will provide high-quality data on the benefits and risks of H-ESD for EGN patients. The . |
