A prediction model and nomogram for technical difficulty of peroral endoscopic myotomy
Peroral endoscopic myotomy (POEM) is a promising endoscopic technique for achalasia. We aimed to establish a regression model and develop a simple nomogram to predict the technical difficulty of POEM in a sing...

MRI radiomic features-based machine learning approach to classify ischemic stroke onset time
We aimed to investigate the ability of MRI radiomics features-based machine learning (ML) models to classify the time since stroke onset (TSS), which could aid in stroke assessment and treatment options.

Controlled hypertension under hemostasis prevents post-gastric endoscopic submucosal dissection bleeding: a prospective randomized controlled trial
Endoscopic submucosal dissection (ESD) is a prominent minimally invasive operative technique for treating early gastrointestinal tumors but can result in postoperative bleeding. We conducted a randomized contr...

Short- and long-term outcomes of endoscopic submucosal dissection for superficial esophageal squamous cell cancer in patients with prior gastrectomy
The surgery for esophageal cancer arising after prior gastrectomy is technically difficult with high morbidity and mortality. Endoscopic submucosal dissection (ESD) is a minimally invasive endoscopic treatment...

Open AccessFactors associated with prominent vessel sign on susceptibility-weighted imaging in acute ischemic stroke
The prominent vessel sign (PVS) on susceptibility-weighted imaging (SWI) is not displayed in all cases of acute ischemia. We aimed to investigate the factors associated with the presence of PVS in stroke patie...

Open AccessDissection-related carotid-cavernous fistula (CCF) following surgical revascularization of chronic internal carotid artery occlusion: a new subtype of CCF and proposed management
The development of carotid-cavernous fistulas (CCFs) during surgical recanalization of chronic internal carotid artery occlusion (ICAO) may be secondary to severe ICA dissection rather than a focal tear of the...

Microscopic positive tumor margin does not increase the rate of recurrence in endoscopic resected gastric mesenchymal tumors compared to negative tumor margin
The endoscopic resection of gastrointestinal mesenchymal tumors (GIMTs) is widely accepted because of its minimal invasiveness. However, one major concern is the high rate of positive microscopic margins remai...
