Procedure definition | An inguinal hernia repair is surgery to fix a weakness or tear in the abdominal wall in the groin area. The hernia itself happens when internal tissue—often a bit of intestine or fat—pushes through that weak spot, causing a visible bulge or discomfort. It’s one of the most common surgeries performed worldwide, with millions done every year.
The goal of repair is to return the bulging tissue to the abdomen and strengthen the weakened muscle layer. Most repairs today use a synthetic mesh patch to reinforce the area and lower the chance of the hernia returning.
There are two main techniques:
• Open repair (Lichtenstein technique): A single 2–3-inch incision is made in the groin. The surgeon pushes the hernia contents back into place, lays a mesh over the defect, and secures it with sutures or tacks.
• Laparoscopic or robotic repair (TEP or TAPP): Several small incisions are made in the lower abdomen. Using a camera and long instruments, the surgeon places a mesh from the inside of the abdominal wall. This “minimally invasive” approach usually causes less pain and allows faster recovery, though it takes longer to perform and requires general anesthesia.
Both approaches are highly effective, and the choice depends on the patient’s health, hernia type (one-sided, both-sided, or recurrent), and the surgeon’s expertise. |
Why it’s done | An inguinal hernia does not heal on its own. Over time, the opening in the muscle wall can enlarge and cause more pain or risk of incarceration (when tissue gets stuck) or strangulation (when blood supply is cut off). Those conditions are medical emergencies that require immediate surgery.
Most people choose to repair a hernia when it becomes painful, enlarging, or affects daily activity. In certain older or minimally symptomatic patients, doctors may offer “watchful waiting,” but studies show that about 70% eventually need surgery because symptoms worsen.
Repairing the hernia restores comfort, prevents dangerous complications, and often improves core strength and mobility. Laparoscopic repair is often recommended for bilateral (both-sided) hernias or recurrent hernias after prior open surgery. |
Risks & complications (with numeric ranges) | Hernia repair is safe, but all operations have risks. Outcomes depend on technique, mesh type, and surgeon experience.
Overall complication rate: 5–10% (most are mild or temporary).
Specific risks include:
• Recurrence: 1–3% in modern mesh repairs; higher (up to 10%) if no mesh or after emergency repair.
• Seroma or hematoma (fluid or blood collection): 1–8%.
• Wound infection: <1–2%.
• Urinary retention: 1–5%, often short-lived.
• Testicular swelling or injury to the spermatic cord: <1%; temporary swelling is more common.
• Nerve irritation or numbness: 5–10% early on, improving over months.
• Chronic postoperative pain (CPIP): any persistent pain occurs in 10–30% of patients, but moderate-to-severe pain that interferes with daily life occurs in 1–12%. Use of gentle mesh fixation and minimally invasive methods can reduce this.
• Conversion from laparoscopic to open: 1–3%.
• Mortality: extremely low, <0.1% in elective cases.
Large studies and registries show that recurrence and pain outcomes are best when surgery is performed by experienced hernia specialists at high-volume centers. |
Recovery | Hospital stay: Most patients go home the same day. Overnight observation may be recommended for older patients or those with other medical conditions.
Activity: Walking is encouraged right after surgery. Light activities (climbing stairs, gentle errands) can resume within 1–2 days. Most people return to desk work or driving within 5–7 days. Avoid heavy lifting (>10–15 lbs / 5–7 kg) for 2–4 weeks, depending on comfort and surgeon advice.
Pain control: Mild to moderate soreness in the groin is normal for several days. Non-narcotic pain relievers (acetaminophen or NSAIDs) usually suffice. An ice pack can reduce swelling during the first 24 hours.
Wound care: Keep incisions clean and dry for 24 hours; showering is usually fine the next day. Adhesive strips or skin glue fall off naturally. Contact your surgeon if you notice increasing redness, drainage, fever, or severe pain.
Diet: You can eat normally the same day. Drink plenty of fluids and use a stool softener to avoid constipation, which can strain the repair.
Return to full activity: Most patients resume unrestricted activity and exercise by 4 weeks. Laparoscopic patients often do so slightly sooner. Full tissue healing continues for several months, but mesh reinforcement allows early movement safely. |
Surgeon types | Inguinal hernia repairs are performed by General Surgeons. Some have additional focus or certification in minimally invasive or hernia surgery, which is beneficial for complex or recurrent cases.
High-volume hernia surgeons—those performing several hundred repairs per year—consistently show lower recurrence and pain rates. For very difficult re-repairs or abdominal-wall reconstructions, some patients are referred to abdominal wall reconstruction specialists at major medical centers. |
