How Long Does Inguinal Hernia Surgery Take?

Most inguinal hernia repairs take between 30 and 90 minutes of actual operating time, depending primarily on whether the surgeon uses an open or minimally invasive technique and whether one or both sides need repair. That range surprises many people, who expect a single clean number from their surgeon. The reality is that the clock in the operating room is shaped by the surgical approach, the type of anesthesia, the complexity of the hernia, and even the surgeon’s experience level. And operating time is only one slice of the day you will spend at the hospital.

Open Repair vs. Laparoscopic Repair

The biggest factor in how long you will be on the table is whether your surgeon performs an open repair or a laparoscopic one. Open inguinal hernia repair, most commonly the Lichtenstein technique, involves a single incision in the groin and placement of a mesh patch. Laparoscopic repair uses small incisions and a camera, with the mesh placed behind the abdominal wall. Both are well-established, but they run on different clocks.

A comparative study of unilateral hernias found that open repair averaged about 47 to 53 minutes, while laparoscopic repair averaged roughly 84 to 90 minutes, depending on whether the hernia was direct or indirect.¹ Another trial reported the gap more dramatically, with open repairs averaging about 65 minutes and laparoscopic TAPP repairs averaging around 120 minutes.² A Cochrane review of the available evidence confirmed the general pattern: laparoscopic repairs consistently take longer.³

That said, the gap may not be as wide in everyday practice as it appears in some individual studies. A large risk-adjusted analysis found that, at the median, laparoscopic repair added only about 8 to 12 minutes compared to open repair done under local anesthesia.⁴ The wide range across studies reflects differences in surgical centers, training, and how strictly the clock is defined. Some studies count from first incision to final suture; others include setup time for the laparoscopic equipment. Either way, if your surgeon is doing a laparoscopic or TEP repair, expect it to take somewhat longer in the operating room than an open Lichtenstein approach.

Where Robotic Surgery Fits In

Robotic-assisted hernia repair is growing in popularity, particularly in the United States. The robot gives the surgeon wristed instruments and three-dimensional vision inside the abdomen, but the equipment takes time to set up, and the procedure currently runs longer than standard laparoscopic repair in most head-to-head comparisons. A systematic review and meta-analysis found that overall operative time was about 160 minutes for robotic versus 90 minutes for laparoscopic repair; for unilateral procedures specifically, the comparison was closer, roughly 88 minutes robotic versus 68 minutes laparoscopic.⁵

A narrative review looking across multiple systematic reviews and randomized trials found that the extra time for robotic repair ranged from about 14 to 33 minutes on average. Two large randomized trials, the RIVAL study and the VOLTAIRE trial, both reported that robotic procedures took roughly twice as long as laparoscopic ones. One exception was the DIRECT trial, which actually found shorter times for robotic repair of both simple and complex hernias. So the picture is not perfectly uniform, but the weight of the evidence says robotic repair currently adds time.⁶ Whether that extra time translates to meaningful differences in recovery or outcomes is a separate question that surgeons are still debating.

One Side or Two

If you have hernias on both sides, the surgery takes longer, but not twice as long. A study of more than 2,800 laparoscopic repairs found that unilateral repair averaged about 45 minutes while bilateral repair averaged about 70 minutes.⁷ A learning-curve study found similar numbers, with unilateral laparoscopic repairs averaging around 55 to 62 minutes and bilateral repairs around 85 to 93 minutes, depending on how far along the surgeon was in their training.⁸ A systematic review and meta-analysis confirmed that bilateral operations take significantly longer than unilateral ones.⁹

The upside is that both sides get fixed in a single session, so you only go through anesthesia and recovery once. The period of disability after bilateral laparoscopic repair appears to be the same as for unilateral, about two weeks in the study cited above. That is a strong argument for repairing both sides at once when they are both symptomatic.

Other Factors That Shift the Clock

Body Weight

Higher body weight makes the technical work harder and tends to extend operative time. A prospective cohort study of hernia repairs found that surgery lasted significantly longer in patients with a BMI of 30 or above, roughly 98 minutes compared with 82 minutes for non-obese patients.¹⁰ The difference was especially pronounced in open repairs. Thicker tissue layers, reduced visibility, and a deeper surgical field all slow things down.

Surgeon Experience

Laparoscopic hernia repair has a well-documented learning curve. A study tracking community general surgeons found that complication rates and surgical times began to level off after about 50 operations.¹¹ The learning-curve study mentioned earlier also showed that experienced surgeons performing laparoscopic repairs shaved about 7 to 8 minutes off their unilateral procedure times compared to their early cases.⁸ If you are curious, asking your surgeon how many hernia repairs they do per year is a reasonable question. High-volume hernia surgeons tend to be faster and have fewer complications.

Emergency vs. Elective Timing

An elective hernia repair, the planned kind, runs more smoothly and quickly than an emergency one. Emergency patients, typically those whose hernias have become incarcerated or strangulated, had a median operative time of 80 minutes compared with 65 minutes for elective patients in one study, along with longer hospital stays and higher rates of surgical site infection.¹² Another study found that emergency groin hernia surgery carried roughly four and a half times the odds of complications compared to an elective repair after reduction.¹³ This is one of the clearest practical takeaways: getting a hernia repaired on a scheduled basis, before it becomes an emergency, generally means a shorter operation and a smoother recovery.

Mesh Fixation Method

During laparoscopic repair, the mesh needs to be secured in place, and surgeons can use either small metal or absorbable tacks or a tissue adhesive (glue). You might wonder if one method takes longer. A meta-analysis of 11 randomized controlled trials found no significant difference in operative time between glue and tacker fixation.¹⁴ A quality-of-life study comparing the two methods in TEP repair reported a similar finding, with tack fixation averaging about 85 minutes and glue fixation about 78 minutes, a difference that was not statistically meaningful.¹⁵ So the fixation method is unlikely to change how long your surgery takes.

How Anesthesia Affects the Timeline

The type of anesthesia changes not just the operating time but the total time you spend in the operating theater. Open inguinal hernia repair can be done under local anesthesia with sedation, spinal anesthesia, or general anesthesia. Laparoscopic repair almost always requires general anesthesia because the abdomen needs to be inflated with gas. A randomized trial comparing the three anesthesia types for open repair found that local anesthesia was associated with the shortest time in surgery and the shortest total time in the operating room. General anesthesia required the most time overall.¹⁶

A large database analysis similarly found that local anesthesia was associated with roughly a 13 percent decrease in operative time and a 27 percent shorter recovery room stay compared to general anesthesia.¹⁷ This makes intuitive sense: general anesthesia involves induction, intubation, and a longer wake-up period, none of which applies when you are awake under local numbing. There is a trade-off in patient satisfaction, though. The same randomized trial found that patients under local anesthesia rated their satisfaction lower than those under spinal or general anesthesia, likely because they were more aware of the procedure.

The Rest of Your Day at the Hospital

Operating time is only part of the picture. Most people want to know how long they will actually be at the hospital. For the vast majority of patients, inguinal hernia repair is a same-day procedure. An observational study across England found that about 87 percent of planned day-case inguinal hernia repairs went home the same day, while roughly 13 percent ended up staying at least one night.¹⁸

After the surgery itself, you spend time in a recovery room waking up from anesthesia and being monitored. How long this takes depends heavily on the anesthesia type. One study of outpatient hernia repair found that patients who received a nerve block with light sedation were ready to go home in about two and a quarter hours on average, while those under spinal anesthesia needed closer to four and a half hours.¹⁹ A large series of more than 2,000 single-incision laparoscopic repairs done under tumescent local anesthesia reported a median recovery room stay of about two hours, with all patients going home the same day.²⁰

Putting it all together, a realistic estimate for your total time at the facility, including check-in, anesthesia preparation, the operation, and recovery room monitoring, is somewhere around three to six hours. The surgery itself is the shortest part. Waiting, preparation, and post-anesthesia observation make up the majority of the day.

Getting Back to Normal Life

Most people are able to drive within a few days of a tension-free mesh repair, whether open or laparoscopic. The practical test is whether you can slam on the brakes hard without hesitation or significant pain, which is typically possible by the third day after mesh-based repair.²¹ Walking and light daily activities can usually resume within a day or two.

For heavier physical activity, the expert consensus has shifted in recent years toward earlier return. A survey of European hernia surgeons found that most recommended returning to sports after a median of two weeks for both open Lichtenstein and laparoscopic repairs. For heavy lifting, the median recommendation was two weeks after open repair and three weeks after laparoscopic repair, though individual surgeon advice ranged from one to four weeks.²² An expert survey from the European Hernia Society similarly concluded that full physical strain, sports, and hard work could resume after about two weeks for laparoscopic inguinal repair and about four weeks for open ventral repair, and that recommendations should not exceed four weeks after uncomplicated surgery to avoid the harms of unnecessary immobilization.²³

The old advice of “no lifting for six weeks” is falling out of favor. Pain remains the best guide: if an activity hurts, ease off. If it does not, you are probably fine to keep going.

Chronic Pain After Hernia Repair

The surgery itself is brief, but the possibility of lingering pain is worth knowing about because it affects how many people weigh their options. Chronic postoperative inguinal pain, defined as pain lasting more than three months after surgery, is more common than most patients expect. A systematic review and meta-analysis found a pooled incidence of about 17 percent, with rates varying by geography: roughly 19 percent in European studies, 15 percent in Asian studies, and about 6 percent in North American studies.²⁴

The encouraging part is that chronic pain tends to diminish over time. A large prospective study tracking more than 1,700 patients found confirmed pain in about 14 percent at four months, dropping to about 6 percent at one year and 4 percent at two years.²⁵ Among those who did develop chronic pain, about a third had a neuropathic component, meaning the pain came from nerve irritation rather than tissue inflammation. At two years, about half of those with chronic pain still described it as moderate or intense, and roughly a quarter were using painkillers for it. The mental health impact was measurable too: patients with chronic pain had clinically significant drops in mental health scores.²⁵

Emergency repair does not appear to raise the long-term chronic pain risk compared to elective repair, which is one reassuring finding for patients who end up in the emergency room with a stuck hernia.¹²

Inguinal Hernia Repair in Children

Pediatric inguinal hernia surgery is a different animal. Children’s hernias are almost always indirect, the anatomy is smaller and simpler, and the repair technique is different: it typically involves closing the opening rather than placing a mesh. As a result, the operations are considerably shorter. A study of laparoscopic pediatric inguinal hernia repair using small needlescopic instruments reported a mean operating time of about 42 minutes for unilateral cases and 46 minutes for bilateral cases.²⁶ Many pediatric open repairs are even quicker. Children also tend to bounce back faster, often running around within a day or two, which can be both a relief and a source of anxiety for parents trying to enforce rest.
