Inguinal hernia is a protrusion of abdominal viscera (most commonly the small intestine) in the groin through a defect in the abdominal wall and is the most common type of extra-abdominal hernia. The basic symptom is the presence of a reducible mass in the inguinal region, which is usually uncomfortable and only occasionally associated with localized distension and involvement pain. As the disease progresses, the mass may gradually increase in size and descend from the groin into the scrotum or labia majora, making walking difficult and interfering with work. Hernia is mostly painless and uncomfortable. When standing, the hernia mass appears immediately and disappears when lying down. Most hernias are elective, but if they are complicated by intussusception, emergency surgery is required. Otherwise, there is a risk of strangulation of the hernia contents, necrosis (mostly of the intestinal canal) and life-threatening effects. The prognosis after surgery is generally good. Before discharge, the patient should also understand that: 1. The incision is closed intradermally and does not require stitch removal. 2. After discharge, keep the incision dry and clean for one week. About ten days, you can take a shower, and after one month, you can take a bath. 3.After discharge, you need to take a proper rest for 1 or 2 weeks. Light laborers can resume work after one month, but within six months, do not engage in strenuous exercise, do not lift (lift) heavy objects, can walk, play tai chi, drive, climb stairs; heavy laborers are engaged in work of lower intensity than the original labor after three months, and then resume normal heavy labor after six months. 4, after discharge, especially to avoid the occurrence of diseases that can cause increased intra-abdominal pressure. For example, cough, constipation, difficulty in urination, etc. to reduce the chance of hernia recurrence. 5. After hernia surgery, very few patients will have recurrence, and some patients will have hernia on the opposite side of the surgery, therefore, it is necessary to contact the doctor in time for outpatient follow-up or discomfort in January after discharge.
