Comparisons of outcomes between ProKnife injection endoscopic submucosal dissection and conventional endoscopic submucosal dissection for large gastric lesions in ex vivo porcine model study: A randomized controlled trial.

ABSTRACT:

Objective

To compare treatment outcomes between injection endoscopic submucosal dissection using ProKnife (P-ESD) and conventional ESD (C-ESD) for gastric lesions.

Methods

In this randomized controlled trial, we compared treatment outcomes of P-ESD and C-ESD for simulated gastric lesions ≥3 cm in resected porcine stomachs. Predictive factors associated with ESD difficulties were investigated using logistic regression analysis.

Results

Seventy lesions were screened; however, two lesions were excluded. A total of 12 endoscopists performed 68 ESDs: 34 P-ESDs and 34 C-ESDs. The ESD procedure time of P-ESD (36.3 [28.4-46.8] min) was significantly shorter than that of C-ESD (46 [36.4-64.6] min; p = 0.0014). The technical success rates did not differ between the P-ESD
