Treatment of Complex Abdominal Hernias

Timing of Intervention

Patients with suspected intestinal strangulation should undergo emergency hernia repair immediately (grade 1C recommendation) 1, 3
Systemic inflammatory response syndrome, contrast-enhanced CT findings, elevated lactate, and other biomarkers are predictive of bowel strangulation and should guide urgency of intervention 1, 4

The American College of Surgeons recommends prosthetic repair with synthetic mesh for patients with intestinal incarceration and no signs of strangulation or concurrent bowel resection 1, 5
Mesh repair is associated with significantly lower recurrence rates compared to tissue repair without increasing wound infection rates 5, 1
For patients with intestinal strangulation and/or concomitant need of bowel resection without gross enteric spillage, emergent prosthetic repair with synthetic mesh is recommended 1, 4

Component separation technique may be useful for large midline abdominal wall hernias (grade 1B recommendation) 1, 4
Diagnostic laparoscopy may be useful for assessing bowel viability after spontaneous reduction of strangulated hernias 1, 6

For intestinal incarceration without ischemia, short-term prophylaxis is recommended 2, 4
For intestinal strangulation and/or concurrent bowel resection, 48-hour antimicrobial prophylaxis is recommended 2, 4
For peritonitis, full antimicrobial therapy is recommended 2, 7

Local anesthesia can be used for emergency hernia repair when bowel gangrene is absent, providing effective anesthesia with fewer postoperative complications 2, 4
General anesthesia should be preferred when bowel gangrene is suspected, intestinal resection is needed, or in cases of peritonitis 2, 4

Delayed diagnosis of strangulated hernias can result in bowel necrosis requiring resection, significantly increasing morbidity and mortality 3
