Thoracic inlet located corrosive oesophageal strictures

Area of Science:

• Gastroenterology
• Thoracic Surgery
• Oesophageal Diseases

Background:

• Cicatricial corrosive oesophageal strictures typically present as multiple lesions.
• Isolated thoracic inlet strictures are uncommon due to the oesophagus's rapid transit nature.
• These strictures pose diagnostic challenges, especially with complete obstruction, and present surgical access difficulties.

Purpose of the Study:

• To investigate the characteristics and management of apparently isolated cicatricial corrosive strictures in the thoracic inlet.
• To evaluate the diagnostic and operative challenges associated with these specific oesophageal strictures.

Main Methods:

• Retrospective review of patients treated for cicatricial corrosive oesophageal strictures.
• Inclusion criteria: apparently isolated strictures in the thoracic inlet.
• Diagnostic methods included oesophagoscopy and contrast barium studies; treatments ranged from resection and anastomosis to reconstructive surgery with gastric or colonic conduits.

Main Results:

• Eleven cases of isolated thoracic inlet strictures were identified among 316 patients.
• All patients achieved restored swallowing function post-treatment.
• Anastomotic leakage occurred in some cases but healed spontaneously without further intervention.

Conclusions:

• Isolated corrosive oesophageal strictures in the thoracic inlet are infrequent and may be more extensive than initially apparent.
• The location presents unique diagnostic and surgical challenges requiring specialized approaches.
