Hernia Repair (Ventral, Umbilical & Incisional Hernia Surgery)

A ventral hernia is a bulge through a weak spot in the front of the abdominal wall. The main types are:

• Umbilical hernias, at the belly button
• Epigastric hernias, above the belly button
• Incisional hernias, through a prior surgical scar, including small laparoscopic port sites

Ventral hernias are among the most commonly repaired conditions in surgery. They don't heal on their own, and many slowly enlarge over time.

The approach is matched to the hernia. Mesh lowers recurrence compared with stitches alone (López-Cano et al., PLoS One, 2018):

• Small umbilical hernias: a short repair, with mesh for most defects larger than 1 cm
• Larger and incisional hernias: laparoscopic or robotic mesh repair
• Large, complex, or recurrent hernias: abdominal wall reconstruction with component separation

Durability is the central challenge. In a national study of 130,660 patients, 1 in 7 needed another operation for recurrence within 5 years (Howard et al., Annals of Surgery, 2023). The study found lower reoperation rates with:

• Minimally invasive surgery
• Mesh
• Myofascial release techniques

That's why technique, mesh position, and patient optimization matter so much.

• Reduce the hernia. Fat or bowel trapped in the hernia sac is returned to the abdomen.
• Close the defect. The fascial edges are brought back together when possible, restoring the midline (linea alba) and abdominal wall function.
• Reinforce with mesh. Mesh spreads tension across a wide area. Mesh can sit in four positions (Albutt and Fagenholz, Journal of Medical Insight, 2023):
  • Onlay: on top of the muscle
  • Inlay: bridging the defect
  • Sublay (retromuscular): behind the muscle
  • Underlay (intraperitoneal): inside the abdomen
• Sublay is considered the most durable position. Sublay placement is associated with lower recurrence (Bittner et al., International Endohernia Society Guidelines, 2019). Current consensus favors it for durability (Maskal et al., Trials, 2025).
• Wide mesh overlap matters. In laparoscopic repair, recurrence fell from about 8.6% with less than 3 cm of overlap to 1.4% with more than 5 cm (Bittner et al., International Endohernia Society Guidelines, 2019).
• Component separation for big defects. Transversus abdominis release (TAR) lets the abdominal wall layers slide toward the midline. That allows tension-free closure of large defects, with mesh in a well-vascularized plane behind the muscles (Maldonado et al., PLoS One, 2025).

• Fewer wound infections with minimally invasive repair:
  • Network meta-analysis (34 RCTs): risk ratio 0.29 with laparoscopic repair (Almiron da R Soares et al., Journal of the American College of Surgeons, 2025)
  • Meta-analysis of 7,826 patients: risk ratio 0.36 (Ajii et al., Hernia, 2026)
• Shorter hospital stays: about 2 days shorter than open repair (Ajii et al., Hernia, 2026).
• Lower long-term reoperation for recurrence. Each of these was associated with fewer reoperations (Howard et al., Annals of Surgery, 2023):
  • Laparoscopic repair: aOR 0.93
  • Robotic repair: aOR 0.85
  • Mesh: aOR 0.88
  • Myofascial release: aOR 0.79
• Much lower recurrence with mesh. In the landmark randomized trial, 10-year recurrence was 32% with mesh vs 63% with suture repair. Abdominal pain was less frequent in the mesh group (Burger et al., Annals of Surgery, 2004).
• Robotic advantages over open repair: fewer complications (OR 0.61), fewer wound infections (OR 0.47), 3.4 fewer hospital days, and fewer readmissions (de'Angelis et al., Surgical Endoscopy, 2024).
• A smoother recovery. In one randomized trial, event-free recovery was 85% after laparoscopic vs 65% after open repair (Bittner et al., International Endohernia Society Guidelines, 2019). Another found a 5-day faster return to work (Earle et al., SAGES Guidelines, 2016).
• Avoiding a hernia emergency. Emergency repair of umbilical, epigastric, or incisional hernias carries up to 15-fold higher mortality, reoperation, and readmission than elective repair (Bittner et al., International Endohernia Society Guidelines, 2019).

• Symptomatic hernias that cause pain, pressure, a growing bulge, skin changes, or activity limits
• Hernias at higher risk of incarceration. Defects of 3–4 cm were most strongly associated with incarceration, as were peri- and infra-umbilical primary hernias (Sneiders et al., World Journal of Surgery, 2019).
• Incisional hernias after prior abdominal surgery, including open bariatric, colon, gynecologic, or transplant surgery
• Recurrent hernias after a prior repair
• Hernias in patients with obesity, including bariatric surgery candidates, who benefit from a coordinated weight and hernia plan
• Patients with minimal symptoms can often choose watchful waiting. In one model, about 39% of patients under watchful waiting eventually needed repair, and 14% of those repairs were emergencies (Wolf et al., Annals of Surgery, 2019).

Emergency surgery is needed for a hernia that becomes stuck, firm, very painful, red, or discolored, or that comes with vomiting or inability to pass gas or stool.

Laparoscopic or robotic repair:

1. General anesthesia
2. Three to five small incisions, placed away from the hernia
3. Release of adhesions and reduction of hernia contents
4. Defect closure with sutures
5. Mesh placement, either inside the abdomen (IPOM) or, increasingly, in the preperitoneal or retromuscular space, using robotic techniques such as TAPP or eTEP (Peñafiel et al., Hernia, 2024)

Open repair:

• Small umbilical or epigastric hernias: a small incision, often with a flat preperitoneal mesh
• Large or complex hernias: open retromuscular (Rives-Stoppa) repair with or without TAR, often combined with scar or excess skin removal when appropriate

Robotic abdominal wall reconstruction: TAR and retromuscular repair can be done robotically for large defects, avoiding a long midline incision in selected patients.

Typical operating time ranges from under an hour for small umbilical hernias to several hours for complex reconstruction.

• Recurrence. It remains the most important long-term risk:
  • Reoperation within 5 years: about 14% nationally (Howard et al., Annals of Surgery, 2023)
  • True recurrence is likely higher, because reoperation can underestimate recurrence up to 5-fold
  • Risk factors: obesity, smoking, prior wound infection, and large defects
• Seroma. This is fluid collection where the hernia was, and it usually resolves on its own.
• Surgical site infection. It's much less common with minimally invasive repair (Almiron da R Soares et al., Journal of the American College of Surgeons, 2025).
• Mesh infection. It may need antibiotics, drainage, or mesh removal. Up to 7% of meshes ultimately require removal for infection in some series (Howard et al., Annals of Surgery, 2023).
• Chronic pain. It's reported by up to a quarter of patients after mesh repair in some studies (Howard et al., Annals of Surgery, 2023).
• Bowel injury. It's uncommon. Robotic repair was associated with fewer intraoperative bowel injuries (OR 0.59) and fewer conversions to open surgery (OR 0.51) than laparoscopy (de'Angelis et al., Surgical Endoscopy, 2024).
• Blood clots, pneumonia, and anesthesia risks, which are higher with larger, longer operations
• Longer operating time with the robot. Robotic repair averaged about an hour longer than laparoscopic repair, without more complications (de'Angelis et al., Surgical Endoscopy, 2024).

• Small umbilical and epigastric repairs: home the same day, back to desk work in a few days
• Laparoscopic and robotic ventral repairs: same day or overnight
• Complex abdominal wall reconstruction: typically a hospital stay of several days, sometimes with temporary drains
• Walking: starts the day of surgery
• Pain control: mostly non-opioid medication, with ice and an abdominal binder for comfort when recommended
• Driving: once off narcotic pain medication and able to brake comfortably

• Most patients have lasting relief from bulge, pain, and activity limits.
• Recurrence risk continues for years, not just the first year. In national data, recurrence kept accumulating through all 5 years of follow-up (Howard et al., Annals of Surgery, 2023).
• Your health habits affect durability. Weight, smoking, and blood sugar influence recurrence for the rest of your life.
• Abdominal wall function and contour improve, especially after midline reconstruction of large hernias.

Functional and health improvements after hernia repair:

• Relief of pain and pressure
• Return to exercise and physical work, which supports cardiovascular and metabolic health
• A much lower risk of a hernia emergency
• Pre-operative optimization of blood sugar and smoking often brings lasting health gains beyond the hernia. In one hernia center, many patients maintained glucose control and smoking cessation long-term after optimization (Holland et al., Surgical Endoscopy, 2025).

Preventing hernia recurrence:

• Stay smoke- and nicotine-free.
• Keep blood sugar controlled.
• Maintain a healthy weight to avoid renewed strain on the repair.
• Treat chronic cough and constipation.
• Return to heavy lifting gradually, as cleared.
• Report any new bulge early.

Dr. Nestor de la Cruz-Muñoz, MD, FACS, DABOM is a minimally invasive, bariatric, and foregut surgeon who performs laparoscopic, robotic, and open hernia repairs.

• Educator of surgeons. He served for 10 years as a bariatric surgery fellowship program director, training 13–14 fellows in advanced laparoscopic and minimally invasive techniques.
• Treats the cause, not just the hole. Obesity is the leading modifiable driver of hernia formation and recurrence. As a bariatric surgeon and obesity medicine specialist (DABOM), he can offer a coordinated weight-and-hernia plan that most hernia programs can't provide, including Medical Weight Loss Program, Sleeve Gastrectomy, and Gastric Bypass (RYGB).
• The right repair for each hernia:
  • Minimally invasive mesh repair for most hernias
  • Robotic or open component separation for large and recurrent hernias
  • Open repair combined with scar or excess skin management when that serves the patient best
• Experience with complex abdomens. That includes prior open surgery, prior mesh, and post-bariatric anatomy.
• One surgeon for the abdominal wall and foregut. See Inguinal Hernia Repair, Hiatal Hernia Repair, and Minimally Invasive Surgery.

Hernia repair is one of the operations Dr. de la Cruz-Muñoz performs most often. Over 25 years in practice he has completed over 15,000 minimally invasive procedures, a caseload that spans hernia, foregut, gallbladder and other abdominal surgery alongside bariatric operations.

• Ventral hernias and reflux are unrelated conditions.
• Heartburn, regurgitation, or a known hiatal hernia are evaluated separately. See Hiatal Hernia Repair and GERD / Acid Reflux.

• Recurrent hernia after a prior suture repair: mesh repair, usually minimally invasive
• Recurrent hernia after prior mesh: repair in a different, untouched plane, often retromuscular with or without TAR
• Mesh infection or chronic mesh pain: evaluation for drainage or mesh removal, with staged reconstruction when needed
• Large recurrent hernias: robotic or open abdominal wall reconstruction

• Ventral and incisional hernia repair is medically necessary surgery, covered by most commercial plans and Medicare.
• Documentation: a physical exam, plus CT imaging for larger, recurrent, or complex hernias to measure the defect and plan the repair.
• Prior authorization is usually required for elective repair.
• Combined procedures are authorized separately, such as abdominoplasty or panniculectomy.

• Stop smoking and all nicotine for at least 4 weeks. Four weeks of abstinence clearly reduces wound-healing and lung complications (Barua et al., ACC Expert Consensus Decision Pathway, 2018). Many hernia centers confirm abstinence with urine cotinine testing (Kushner et al., Hernia, 2021).
• Blood sugar control. Expert consensus advises avoiding elective repair when HbA1c is above 8%. Risk rises above 6.5% (Kushner et al., Hernia, 2021). Some centers use 7.2% or less as a target (Holland et al., Surgical Endoscopy, 2025).
• Weight optimization, when time and symptoms allow.
• CT scan for larger or recurrent hernias.
• Medication review. Blood thinners and GLP-1 medications are managed as directed by your surgical and anesthesia teams.
• Arrange a ride home, plus help for the first few days.

• Small and minimally invasive repairs: a regular diet the same day, as tolerated
• Complex reconstruction: liquids first, then advancing over 1–2 days
• High-fiber foods and fluids to prevent straining
• A stool softener while on pain medication
• Protein first for healing

• Walk the day of surgery, and often afterward.
• Small repairs: light activity right away, with gradual return to exercise over 2–4 weeks.
• Laparoscopic and robotic ventral repairs: avoid heavy lifting for about 4 weeks, then progress as cleared.
• Large reconstructions: restrictions may last 6–12 weeks.
• Wear an abdominal binder if recommended.

Strength and Healing

• A strong core supports the repair once healing is complete.
• Gradual return to resistance training, as cleared.
• Protein-forward nutrition supports healing and mesh integration.

For patients from abroad, the length of stay depends on the hernia: a few days for routine repairs, and one week or more for complex abdominal wall reconstruction. Sending CT images ahead of time allows accurate planning before travel.
