An inguinal hernia is the most common abdominal hernia. Inguinal hernia surgery is the most performed general and abdominal surgery. We divide them into inguinal and femoral. Inguinal hernias are more common and prevalent in men, while femoral hernias are more common in women. Inguinal hernias are divided into direct (medial) and indirect (lateral). Indirect ones are more common and they can be congenital or acquired, while direct ones are always acquired. In the clinical presentation of inguinal hernias, swelling in the groin is visible and the most common symptom is pain or discomfort. However, the hernia can be incarcerated and the symptoms of bowel obstruction can appear. Anamnesis and a clinical examination are sufficient to make a diagnosis. In cases where there are doubts and to narrow down the differential diagnosis, which is very broad, radiological imaging methods are available. In symptomatic inguinal hernias that are not strangulated, manual reduction can be performed to delay surgery. But the only permanent form of treatment is surgical treatment, which is indicated in all inguinal hernias except for asymptomatic inguinal hernias that are only monitored. The principle of surgical treatment of inguinal hernia boils down to treating the hernial sac and the hernial neck with hernioplasty. Operations are performed using open repair and minimally invasive methods, i.e. laparoscopic and robot-assisted hernioplasty. Open repairs are divided into open primary tissue approximation nonmesh and open tension- free repairs. Today, the most common method of treating inguinal hernias is the Lichtenstein technique, which belongs to open tension- free repairs. However, new recommendations suggest that laparoscopic treatment is the gold standard. Studies show that it is associated with faster recovery, reduced postoperative pain, and similar recurrence rates compared to open hernioplasty. But if the surgeon does not have enough experience with the laparoscopic method of treatment because the learning curve is much longer, open repairs are recommended. Robotic surgery of inguinal hernias currently does not show advantages in comparison with laparoscopy, and this suggests that it still needs to be improved.
