Summary
This study reports a rare case of jejuno-jejunal invagination caused by an epithelioid sarcoma, a rare tumor type. This finding highlights a novel presentation of epithelioid sarcoma in the proximal jejunum.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Pathology
Background:
- Jejuno-jejunal invagination is uncommon, typically resulting from benign conditions.
- Epithelioid sarcoma is a rare histological subtype of sarcoma with limited published cases.
- Sarcomas of the small intestine are rare, with epithelioid sarcoma being exceptionally infrequent.
Purpose of the Study:
- To document a unique case of jejuno-jejunal invagination.
- To describe the presentation of a jejunal epithelioid sarcoma.
- To contribute to the literature on rare gastrointestinal sarcomas.
Main Methods:
- Case report of a 70-year-old male patient.
- Diagnostic imaging to identify jejuno-jejunal invagination.
- Surgical intervention and histopathological analysis of the resected specimen.
Main Results:
- Diagnosis of jejuno-jejunal invagination confirmed.
- Identification of epithelioid sarcoma within the wall of the proximal jejunum.
- The tumor was located on the invaginated segment (ansa).
Conclusions:
- Epithelioid sarcoma has not been previously reported to originate in the proximal jejunum.
- Jejuno-jejunal invagination as a presentation of jejunal epithelioid sarcoma is novel.
- This case expands the known clinical spectrum of epithelioid sarcoma.

01:22Esophageal Perforation-I: Introduction
Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus.

01:28Esophageal Perforation-II: Clinical Manifestations and Management
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.

01:21Barrett Esophagus-II: Clinical Manifestations and Management
Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure entails...

01:29Intestinal Obstruction I: Introduction
Intestinal obstruction is a partial or complete blockage of the small or large intestine that disrupts the normal flow of intestinal contents through the lumen. This interruption impairs digestion, absorption, and fluid balance, and may lead to serious complications if not treated promptly.Mechanical ObstructionMechanical obstruction occurs when a physical blockage prevents intestinal contents from passing, arising from within the lumen or the bowel wall, or from external compression.Adhesions,...
01:07Intestinal Obstruction II: Pathophysiology
Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...
01:21Barrett Esophagus-I: Introduction
Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more similar...
