Computer-assisted diagnosis of early esophageal squamous cell carcinoma using narrow-band imaging magnifying endoscopy  (FREE ACCESS)

Yuan-Yuan Zhao, Di-Xiu Xue, Ya-Lei Wang et al.

Artificial intelligence was used to characterize intrapapillary capillary loops (IPCLs) for the diagnosis of esophageal squamous neoplasia with magnifying narrow-band imaging. The developed model had a diagnostic accuracy similar to that of experienced endoscopists and superior to that of the less experienced. Artificial intelligence for characterizing IPCLs could potentially assist in lesion selection for endoscopic resection.

Feasibility of the peroral endoscopic myotomy (POEM) procedure with a new small caliber endoscope (thin-POEM) in patients with achalasia  (FREE ACCESS)

Oscar Víctor Hernandez Mondragón, Marina Alejandra González Martínez, Omar Michel Solórzano Pineda et al.

Study examining the feasibility and safety of performing peroral endoscopic myotomy using a small-caliber endoscope. With slight modifications of the devices and closure method, the authors achieved successful submucosal myotomy in 45 patients, with excellent clinical response. The advantage of this new technique lies in using a smaller endoscope and potentially creating a smaller tunnel, but further studies are needed.
