      BACKGROUND: The aim of this study is to report a novel, multicenter experience with the diverticular peroral endoscopic myotomy (D-POEM) technique in the management of esophageal diverticula.

      METHODS: This is a multicenter, international, retrospective study involving three centers. D-POEM was performed using the principles of submucosal endoscopy.

      RESULTS: A total of 11 patients with an esophageal diverticulum (Zenker's 7, mid-esophagus 1, epiphrenic 3) were included. The mean size of ...

      BackgroundWith the development of minimally invasive endoscopic approaches for the esophagus in recent years, peroral endoscopic myotomy (POEM) in the treatment of esophageal diverticulum has been described recently in some reports due to its successful outcomes. The aim of this study is to report our experience with the use of diverticular POEM (D-POEM) technique in the management of esophageal diverticulum.MethodsThis retrospective study included consecutive patients with symptomatic ...

      During peroral endoscopic myotomy (POEM), creation of the tunnel is highly technically demanding and mucosal injury is one of the most common potential complications. We explored a method without a submucosal tunnel, which we call open peroral endoscopic myotomy (O-POEM). This study aimed to assess the feasibility and safety of O-POEM. O-POEM was performed on 82 patients with achalasia. Treatment success was defined as an Eckardt score of less than or equal to 3 after the myotomy. ...

      BackgroundColorectal endoscopic submucosal dissection (ESD) has always been challenging for endoscopists, but the procedure can be facilitated after adequate exposure of submucosal layer and cutting line. We developed a traction method based on gravity for facilitating colorectal ESD, referred as magnetic bead-assisted ESD (MBA-ESD). This study aimed to compare the safety and effectiveness of MBA-ESD and conventional ESD for treating large superficial colorectal tumors.MethodsThis ...

      BACKGROUND: Endoscopic biliary stenting is a well-established palliative treatment for patients with unresectable distal malignant biliary obstruction (MBO). However, the main problem with stent placement is the relatively short duration of stent patency. Although self-expanding metal stents (SEMSs) have a longer patency period than plastic stents (PSs), the higher costs limit the wide use of SEMSs. A PS with an antireflux valve is an attractive idea to prolong stent patency, but no ...

      BackgroundThe risk factors of duodenal injury from distal migrated biliary plastic stents remain uncertain. The aim of this study was to determine the risk factors of distal migration and its related duodenal injury in patients who underwent placement of a single biliary plastic stent for biliary strictures.MethodsWe retrospectively reviewed all patients with biliary strictures who underwent endoscopic placement of a single biliary plastic stent from January 2006 to October ...

      BACKGROUND: Endoscopic submucosal dissection (ESD) is effective for treating T1a early esophageal squamous cell carcinoma (ESCC). However, occasional recurrences are inevitable. This trial was designed to clarify the efficacy of combining ESD with additional radiotherapy in the treatment of T1a ESCC.

      METHODS: Between January 2015 and September 2018, patients with early ESCC (T1aN0M0) following ESD were randomly assigned (1:1) to the radiotherapy group or non-radiotherapy group. Patients ...

      Circular RNA (circRNA) is a type of non-coding RNA characterized by a covalently closed continuous loop. CircRNA is generated by pre-mRNA through back-splicing and is probably cleared up by extracellular vesicles. CircRNAs play a pivotal role in the epigenetic regulation of gene expression at transcriptional and post-transcriptional levels. Recently, circRNAs have been demonstrated to be involved in the regulation of liver homeostasis and diseases. However, the epigenetic role and ...

      Esophageal cancer poses diagnostic, therapeutic and economic burdens in high-risk regions. Artificial intelligence (AI) has been developed for diagnosis and outcome prediction using various features, including clinicopathologic, radiologic, and genetic variables, which can achieve inspiring results. One of the most recent tasks of AI is to use state-of-the-art deep learning technique to detect both early esophageal squamous cell carcinoma and esophageal adenocarcinoma in Barrett's ...

      BACKGROUND AND AIM: Diagnosis of esophageal squamous cell carcinoma (ESCC) is complicated and requires substantial expertise and experience. This study aimed to develop an artificial intelligence (AI) system for detecting superficial ESCC under multiple endoscopic imaging modalities.

      METHODS: Endoscopic images were retrospectively collected from West China Hospital, Sichuan University as a training dataset and an independent internal validation dataset. Images from other four hospitals ...

      BACKGROUND AND AIMS: Video capsule endoscopy (VCE) is limited by poor image quality and incomplete small-bowel transit. This study was designed to evaluate the diving method for VCE in the examination of small-intestinal disease.

      METHODS: From July 2017 to September 2017, eligible patients were randomly assigned to 2 groups, the diving group and the control group. For the diving group, 500 mL of water was administered every hour when the capsule reached the small bowel. The primary ...

      Achalasia is a type of esophageal motility disorder, consisting of relaxation dysfunction of the lower esophagus and disturbed esophageal peristalsis. Related clinical symptoms include dysphagia, regurgitation, chest pain, and weight loss. Traditional treatment options include endoscopic botulinum toxin injection, endoscopic pneumatic dilation, and laparoscopic Heller's myotomy. These therapies mainly relieve symptoms by reducing the pressure on the lower esophageal sphincter and ...

      RATIONALE: The management of complete obstruction of anastomosis following colorectal surgery is challenging. Some modified minimally invasive methods have been reported to be successfully implemented in some cases. In this case report, we present a case to share our experience.

      PATIENT CONCERNS: A 64-year-old man underwent low anterior resection and single barrel ileostomy for rectal cancer 5 months ago. Completely obstructed anastomotic stenosis was found during colonoscopy.
