Can You Push an Inguinal Hernia Back In?
Yes, you can attempt to manually reduce a reducible inguinal hernia back into the abdomen, but this should only be done if the hernia is not strangulated and the patient shows no signs of bowel compromise—attempting reduction of a strangulated hernia risks a dangerous condition called "reduction en masse" where the hernia sac reduces but the bowel remains trapped and ischemic. 1
When Manual Reduction is Appropriate
- Reducible hernias without signs of strangulation can be safely pushed back through gentle manual pressure with the patient lying supine and relaxed 2, 3
- The hernia contents (typically bowel or omentum) should slide back smoothly into the abdominal cavity without resistance 4
Critical Warning Signs That Prohibit Reduction Attempts
Do NOT attempt manual reduction if any of these are present:
- Severe, unrelenting pain suggesting strangulation 2, 3
- Skin changes over the hernia (erythema, warmth, discoloration) 4
- Systemic inflammatory response syndrome (SIRS) criteria (fever, tachycardia, elevated WBC) 2
- Firm, tender, irreducible mass that does not compress 4
- Signs of bowel obstruction (nausea, vomiting, abdominal distension) 2
- Peritoneal signs on examination 4, 2
These findings indicate potential strangulation requiring immediate emergency surgical intervention to prevent bowel necrosis and death 2, 3
The Danger of "Reduction En Masse"
- This rare but serious complication occurs when you manually reduce the external hernia sac back through the abdominal wall, but the bowel contents remain incarcerated or strangulated in the preperitoneal space 1
- The hernia appears reduced externally, but the bowel is still trapped and ischemic internally 1
- Small bowel obstruction typically follows, requiring urgent trans-abdominal surgical repair 1
- CT imaging is the investigation of choice if reduction en masse is suspected, as clinical diagnosis is extremely difficult 1
Management Algorithm After Successful Reduction
- Even if you successfully reduce the hernia, the patient still requires surgical referral for definitive mesh repair, as the hernia will recur 2, 3, 5
- If the hernia spontaneously reduces before surgical assessment, diagnostic laparoscopy (hernioscopy) should be considered to evaluate bowel viability and rule out occult ischemia 4, 2
- One study showed that hernioscopy after spontaneous reduction decreased hospital stay and prevented unnecessary laparotomies in high-risk patients 4
When Emergency Surgery is Mandatory
- Suspected strangulation requires immediate surgical intervention—delayed diagnosis beyond 24 hours is associated with significantly higher mortality rates 2, 5
- Predictive factors for strangulation include elevated lactate, serum CPK, D-dimer levels, and contrast-enhanced CT findings showing bowel wall ischemia 2, 5
- Femoral hernias carry an 8-fold higher risk of requiring bowel resection and should be treated with particular urgency 5
Common Pitfall to Avoid
The most dangerous error is attempting to reduce a strangulated hernia or assuming a hernia is safe after reduction without proper assessment—this can mask ongoing bowel ischemia and lead to perforation, sepsis, and death 2, 3, 1
