Summary
Endoscopic stenting of the esophagus (ESE) is safe and effective for esophageal cancer. Delivery devices with proximal opening offer better visual positioning and may be more convenient for esophageal stent placement.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Medical Devices
Background:
- Malignant unresectable esophageal tumors often cause dysphagia.
- Endoscopic stenting of the esophagus (ESE) is a palliative treatment option.
- Various delivery devices (DDs) exist for esophageal stent implantation.
Purpose of the Study:
- To determine the optimal technique for ESE using different DDs.
- To analyze the immediate and long-term outcomes of ESE based on DD type.
Main Methods:
- A comparative study of ESE was conducted in 83 patients.
- Group 1: 41 patients received metal stents via a knitted tubular casing DD (proximal or distal opening).
- Group 2: 42 patients received stents via a contracting outer shell DD.
Main Results:
- Technical success was 100% in both groups.
- The contracting outer shell DD (Group 2) showed significantly less "stumbling" (14.6% vs 0%, p=0.011).
- Stent repositioning was more frequent in Group 2 (38.1% vs 17.1%, p=0.033), especially with distal opening stents.
Conclusions:
- ESE is a safe and effective procedure for dysphagia palliation in esophageal cancer.
- DDs with proximal opening facilitate better visual stent positioning.
- Consideration of DD features is important for optimizing esophageal stenting techniques.

Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

427
An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

01:30Esophageal Strictures-I: Introduction
317
Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

01:28Esophageal Perforation-II: Clinical Manifestations and Management
181
Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.

379
Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers,...
