Management of Inguinal Hernias

Initial Assessment and Management Decision

The American College of Surgeons recommends determining if the hernia is reducible or incarcerated/strangulated to guide the urgency and approach of surgical intervention 1
Patients with suspected intestinal strangulation should undergo emergency hernia repair immediately to prevent bowel necrosis and increased morbidity/mortality 2, 1

The standard approach for non-complicated inguinal hernias is mesh repair, which is strongly recommended by the American Hernia Society 1
Laparoscopic approaches, such as transabdominal preperitoneal (TAPP) and totally extraperitoneal (TEP), offer advantages including reduced postoperative pain medication requirements, lower wound infection rates, and faster return to normal activities 1

Emergency surgical repair is mandatory for strangulated hernias to prevent intestinal ischemia, according to the World Journal of Emergency Surgery 2, 1
Systemic inflammatory response syndrome (SIRS) and contrast-enhanced CT findings are predictive of bowel strangulation 2
Delayed diagnosis (>24 hours) is associated with higher mortality rates 2

Hernioscopy can be used to evaluate bowel viability, avoiding unnecessary laparotomy, as recommended by the American College of Surgeons 1
Local anesthesia is recommended for emergency inguinal hernia repair in the absence of bowel gangrene 1
Risk factors for bowel resection include lack of health insurance, obvious peritonitis, and femoral hernia 2

Monitor for potential complications including wound infection, chronic pain, and recurrence, which can be significantly lower with mesh repair 1
Antimicrobial prophylaxis is recommended for 48-hour antimicrobial prophylaxis for intestinal strangulation and/or concurrent bowel resection 1

Delaying repair of strangulated hernias can lead to bowel necrosis and increased morbidity/mortality, as warned by the World Journal of Emergency Surgery 2, 1
Overlooking contralateral hernias can be avoided by considering a laparoscopic approach 1

The hernia contents, typically bowel or omentum, should slide back smoothly into the abdominal cavity without resistance, as noted by the World Journal of Emergency Surgery 3
Skin changes over the hernia, such as erythema, warmth, or discoloration, are a contraindication for manual reduction, according to the World Journal of Emergency Surgery 4
A firm, tender, irreducible mass that does not compress is a contraindication for manual reduction, as reported by the World Journal of Emergency Surgery 3, 4
Peritoneal signs on examination are a contraindication for manual reduction, as noted by the World Journal of Emergency Surgery 4

Even if manual reduction is successful, diagnostic laparoscopy should be considered to evaluate bowel viability and rule out occult ischemia, as suggested by the World Journal of Emergency Surgery 3
Hernioscopy after spontaneous reduction can decrease hospital stay and prevent unnecessary laparotomies in high-risk patients, according to the World Journal of Emergency Surgery 3

In patients with cirrhosis and ascites, control ascites before elective herniorrhaphy, as uncontrolled ascites increases recurrence and complication rates, according to the American Association for the Study of Liver Diseases 5, 6
The American Association for the Study of Liver Diseases recommends laparoscopic approaches for hernia repair in patients with cirrhosis and ascites when surgery is necessary 5

Immediate surgical repair is mandatory in cases of hemodynamic instability, as recommended by the European Association for the Study of the Liver 5
