Umbilical & Epigastric Hernia — Watchful Waiting vs. Repair, Technique Selection
Source: Guidelines for treatment of umbilical and epigastric hernias from the European Hernia Society and Americas Hernia Society, British Journal of Surgery, 2020

Guideline: Conditional
Guideline: Not recommended

Diagnosis
Diagnostic criteria
A primary hernia with its center at the umbilicus (umbilical) or close to the midline above the umbilicus (epigastric), presenting as a bulge with or without pain/discomfort. Defect size (maximum transverse diameter) is classified as small (<1 cm), medium (1–4 cm), or large (>4 cm) per the EHS/AHS classification, which guides treatment strategy.
⚠ Alarm features (investigate before diagnosing)
- Signs of incarceration (irreducible, tender, firm bulge)
- Signs of strangulation (severe pain, skin changes, systemic toxicity, signs of bowel obstruction) — surgical emergency
- Suspected additional abdominal wall defects, large hernia, obesity, or loss of domain — warrants preoperative imaging
Initial workup
| Test | When to order |
|---|---|
| Physical examination | Sufficient for diagnosis and sizing in most patients; imaging is not routinely required. |
| Ultrasound or CT | Large hernias, potential loss of domain, obesity, unclear defect size, or suspicion of additional defects — to plan the surgical approach. |
Decision Points
❓ Is the umbilical/epigastric hernia symptomatic?
❓ What is the defect size?
❓ Is the patient at higher risk of wound complications (obesity, smoking) or does the defect require a larger mesh?
Treatment
Watchful waiting
1
Watchful waiting with patient counseling
Weak/Conditional (Guideline recommendation) — appears safe based on available data
- Dose
- —
- Duration
- Ongoing; reassess if symptoms develop
- Evidence level
- Low (limited outcome data)
- Avoid if
- Signs of incarceration/strangulation
- If no response ClinicoQ pathway
- Approximately 20% of watchfully-waited patients eventually proceed to surgery as symptoms develop
Suture repair may be considered (selected small defects)
1
Primary suture repair (no mesh)
Conditional (Guideline recommendation) — may be considered for small defects, though mesh reduces recurrence even in this group
- Dose
- — surgical procedure
- Duration
- Elective
- Evidence level
- Low-Moderate
- Avoid if
- Defect ≥1 cm (mesh preferred)
- If no response
- —
Open repair with preperitoneal flat mesh
1
Open repair with a flat mesh placed in the preperitoneal space
Strong (Guideline recommendation) — recommended approach for symptomatic umbilical/epigastric hernias
- Dose
- — surgical procedure
- Duration
- Elective
- Evidence level
- Moderate
- Avoid if
- Active wound infection at the surgical site
- If no response
- —
Laparoscopic repair
1
Laparoscopic mesh repair
Conditional (Guideline recommendation) — reserved for larger defects and patients at higher risk of wound complications, where it lowers wound complication rates versus open repair
- Dose
- — surgical procedure
- Duration
- Elective
- Evidence level
- Low-Moderate
- Avoid if
- Small, uncomplicated defect in a standard-risk patient (open repair is simpler and equally effective there)
- If no response
- —
✕ Treatments the guideline advises against
Watchful waiting for a hernia with signs of incarceration or strangulation: This is a surgical emergency; watchful waiting only applies to genuinely asymptomatic hernias.
