How A General Surgeon Troubleshoots Hernias

Groin hernias in the ED are a bedside diagnosis with a high-stakes split: reducible and incarcerated cases may be managed conservatively, but strangulation is a surgical emergency. Inguinal and femoral hernias behave differently, and reduction technique matters as much as the decision to reduce at all.

Emergency Evaluation of Groin Hernias

• Strangulation red flags: Overlying skin color change, obstructive symptoms, and severe pain should make you presume strangulation rather than a simple incarcerated hernia, and that distinction is worth hearing in the episode.
• Incarcerated versus strangulated: An incarcerated hernia is chronically nonreducible without bowel ischemia, while strangulation adds compromised blood supply, escalating urgency even before labs are back.
• Inguinal versus femoral patterns: Femoral hernias are about four times more common in women and carry a slightly higher operative risk, while inguinal hernias are more prevalent in men.
• CT over ultrasound: CT is the preferred imaging test because it defines direct, indirect, and femoral anatomy while also assessing bowel status and alternative groin diagnoses.
• Lactate as baseline: Lactate does not diagnose strangulation, but it is useful as a resuscitation baseline when bowel ischemia or ongoing obstruction is on the table.

Reduction, Observation, and Surgical Handoff

• Never reduce strangulation: Do not attempt bedside reduction when strangulation is suspected, because reducing necrotic bowel can seed bacteria into the abdomen; call surgery early.
• Taxis setup basics: Trendelenburg, ice, analgesia, and patience set up successful reduction of a non-strangulated hernia, with a few practical nuances we get into in the chapter.
• Neck-first reduction technique: The key maneuver is pressure at the neck of the defect rather than the tip of the bulge, slowly decompressing edematous contents back through the opening.
• Time-intensive reduction attempts: Hernia reduction is often slow and methodical rather than forceful; some attempts take over an hour, and intolerance may be the sign to stop.
• Post-reduction PO challenge: After successful ED reduction, a PO challenge is the bedside check that symptoms and transit have truly improved before discharge.
• High-yield surgical handoff: Surgeons need the symptom timeline, whether the hernia is new or chronic, any abrupt change, and signs of obstruction, ideally paired with imaging already in progress.
