Outcomes of anterior versus posterior peroral endoscopic myotomy 2 years post-procedure: prospective follow-up results from a randomized clinical trial
Fig. 1 Peroral endoscopic myotomy, anterior approach (12 to 2 o’clock position), in a 45-year-old woman with type I achalasia. a, b Initially, the gastroscope was advanced to the mid-esophagus and a mucosal bleb was created by submucosal injection of mixed solution of 1% indigo carmine and saline. Using a triangular tip (TT) knife, a 1.5-cm mucosal incision was performed. c, d Following access to the submucosal space, spray coagulation (50W, effect 2) was utilized to dissect the submucosal fibers and create a submucosal tunnel. e The tunnel was extended 2cm into the gastric cardia. Using the TT knife, a full-thickness myotomy was performed. f Following completion of the myotomy, the gastroscope was withdrawn from the submucosal tunnel and the mucosal incision site was secured with clips.
Endoscopic management of superficial nonampullary duodenal tumors: European Society of Gastrointestinal Endoscopy (ESGE) Guideline
Fig. 1 Sporadic duodenal adenoma: different macroscopic presentations. a Type 0-Is with milk-white mucosa; b Type 0-IIa with reddish mucosa; c Type 0-IIa with milk-white mucosa.
A deep learning-based system for identifying differentiation status and delineating the margins of early gastric cancer in magnifying narrow-band imaging endoscopy
Fig. 2 Representative images of convolutional neural network (CNN)1 identifying the differentiation status of EGCs for: a differentiated EGC predicted by CNN1 (to show results intuitively, confidence of differentiated EGC was outputted as “1 − raw prediction confidence”); b undifferentiated EGC predicted by CNN1 (confidence of undifferentiated EGC was outputted as raw prediction confidence).

“Art in endoscopy” is an initiative of four gastroenterologists in training that aims to display examples of the incidentally beautiful images that are sometimes encountered in regular endoscopic practice.
One-year results of gastric peroral endoscopic myotomy for refractory gastroparesis: a French multicenter study
Fig. 1 Endoscopic images of the gastric peroral endoscopic myotomy (G-POEM) procedure showing: a the pylorus prior to the procedure; b the longitudinal mucosal incision; c submucosal tunneling; d the axis of the tunnel being checked; e the end of the myotomy; f closure of the mucosal entry.
Double-balloon endoscopy facilitates efficient endoscopic resection of duodenal and jejunal polyps in patients with familial adenomatous polyposis
Fig. 3 Endoscopic and pathological images of the lesion in patient #5 showing: a a 0-IIa + IIc lesion 7mm in diameter in the third portion of the duodenum; b the lesion being removed by endoscopic mucosal resection with injection; c histopathological appearance of the lesion (stained with hematoxylin and eosin [H&E], × 4), which was an intramucosal carcinoma, with no residual tumor at the resection site.
