[Spontaneous esophageal rupture]

Area of Science:

• Gastroenterology and Surgery
• Pathology
• Medical Microbiology

Context:

• Spontaneous esophageal rupture is a rare but life-threatening condition.
• Previous literature highlights high mortality rates and challenges in management.
• Understanding the underlying pathophysiology is crucial for improving patient outcomes.

Purpose:

• To describe clinical observations and outcomes of five spontaneous esophageal rupture cases.
• To investigate the morphological changes in the esophageal wall following rupture.
• To explore the potential role of pre-existing esophageal wall alterations in rupture etiology.

Summary:

• Five cases of spontaneous esophageal rupture were analyzed, with one patient recovering.
• All patients presented with acute onset, esophageal wall phlegmon, and bacterial shock.
• Early mediastinal drainage and aspiration facilitated healing, with mature scars noted at 4 months.
• Morphological studies revealed neuro-muscular coordination disturbances and muscle atrophy in the esophageal circular layer.
• These findings suggest that pre-existing muscle alterations may predispose the esophagus to rupture under increased pressure, such as during vomiting.

Impact:

• Early surgical intervention, specifically mediastinal drainage, is critical for improving survival rates.
• The study identifies pre-existing esophageal muscle abnormalities as a potential contributing factor to spontaneous rupture.
• Findings contribute to a better understanding of the pathophysiology, potentially guiding future preventative or therapeutic strategies.
