Overview
Obstructed incisional hernia with gangrene is a severe surgical emergency characterized by compromised blood supply to herniated tissue, leading to tissue necrosis and potential systemic complications. Prompt surgical intervention is critical to prevent mortality and morbidity 1.Diagnosis
Clinical presentation includes severe abdominal pain, distension, and signs of systemic inflammatory response syndrome (SIRS) 1.
Imaging studies (CT abdomen) can confirm the presence of hernia, obstruction, and signs of gangrene 1.
Laboratory findings often reveal elevated inflammatory markers and may indicate pre-operative anaemia 1.Management
Immediate surgical intervention: Emergent surgical exploration and resection of necrotic tissue, with repair of the hernia defect using synthetic mesh when feasible 1.
Management of anaemia: Pre-operative correction of anaemia may improve outcomes; consider blood transfusion if haemoglobin levels are low 1.
Infection control: Prophylactic or targeted antibiotic therapy based on culture results to prevent or manage sepsis 1.
Supportive care: Intensive care unit (ICU) monitoring for hemodynamic stability, respiratory support, and management of multi-organ dysfunction 1.Special Populations
Pre-operative anaemia: Particularly relevant in elderly patients, where pre-operative anaemia is associated with increased mortality and prolonged hospital stay 1.
Comorbidities: Patients with comorbidities such as cardiovascular disease may have worse outcomes; careful risk stratification is essential 1.Key Recommendations
Initiate urgent surgical intervention for obstructed incisional hernia with gangrene to reduce mortality risk (Evidence: Moderate 1).
Assess and correct pre-operative anaemia to potentially improve postoperative outcomes (Evidence: Moderate 1).
Provide intensive postoperative care including hemodynamic monitoring and appropriate antibiotic prophylaxis to manage complications (Evidence: Moderate 1).References
