Does the Pittsburgh Severity Score predict outcome in esophageal perforation?

Area of Science:

• Gastroenterology
• Thoracic Surgery
• Surgical Emergency Management

Background:

• Esophageal perforation is a rare but serious surgical emergency with no established optimal management.
• The Pittsburgh Severity Score (PSS) aims to stratify severity and guide treatment for esophageal perforations.
• Limited research exists on the PSS's validity, particularly in UK populations.

Purpose of the Study:

• To validate the Pittsburgh Severity Score (PSS) in a UK population.
• To explore the PSS's utility in stratifying esophageal perforation patients into subgroups with different outcomes.

Main Methods:

• Retrospective analysis of 87 esophageal perforation cases at Queen Elizabeth Hospital, Birmingham (2003-2017).
• Data collected on clinical presentation, diagnosis, management, and outcomes.
• PSS predictive performance assessed against complications, mortality, and length of stay.

Main Results:

• Overall in-hospital mortality was 13%; 46% of patients experienced post-perforation complications.
• The PSS was not significantly predictive of overall complications or mortality (AUROC 0.62-0.69).
• Subgroup analysis revealed the PSS significantly predicted complications in Boerhaave's perforations (AUROC 0.86).

Conclusions:

• The PSS has some utility in esophageal perforation management but its predictive value varies.
• The PSS is more valuable for predicting outcomes in spontaneous (Boerhaave's) perforations.
• Further validation in diverse populations is warranted.
