1.Why do children get hernia? A: Inguinal hernia includes hiatal hernia, straight hernia and femoral hernia. The vast majority of pediatric inguinal hernias are hiatal hernias. The mechanism of occurrence is that the peritoneal sheath is not occluded, but remains open or partially open, and under the condition of increased abdominal pressure (such as crying, coughing, running and jumping or constipation), the abdominal organs enter into it (mostly small intestine, but also ovaries for girls) and a congenital inguinal hernia is formed. 2.Q: What is the performance of a child with hernia? A: In the case of increased abdominal pressure (such as crying, coughing, running and jumping or constipation), a type of oval swelling, soft and elastic, appears in one or both inguinal regions. The swellings may disappear on their own after lying down quietly. If the swelling is gently pushed upward by hand, it may become smaller until it disappears, and a “gurgling” sound may be heard (not always in girls). If the swelling does not disappear on its own and is painful, then the hernia contents are embedded (stuck). 3.Q: What is the manifestation of a stuck hernia in a child? A: A painful swelling in the inguinal region or scrotum is manifested by the child suddenly crying or pointing his finger at the swelling to indicate pain. It may be accompanied by nausea and vomiting, stopping bowel movements and other manifestations of intestinal obstruction (not necessarily in girls). On examination, a swelling in the inguinal region is visible, hard and painful to palpation. 4.Q: What should I do if my child has a stuck hernia? A: Go to the pediatric surgery department quickly and let the specialist determine whether the hernia can be repositioned manually. If the repositioning fails or is not suitable for manual repositioning, emergency surgery should be performed. 5.Q: How should a child with a hernia be treated? A: Once diagnosed, surgery should be performed as soon as possible (unless the child is preterm, weighing <3kg, gestational age + postnatal weeks <60 weeks). Surgery is not age-restricted, as there is a risk of hernia impaction with serious consequences while waiting. Laparoscopic high ligation of the inguinal hernia sac is an option. Wearing a hernia belt for treatment is ineffective, painful and still requires surgery. Not recommended! 6.Q: Which is better: laparoscopic surgery or traditional open surgery? A: Compared with traditional open surgery, laparoscopic surgery has the following advantages: no dissection of the spermatic cord structure, minimal trauma. It is possible to investigate whether the contralateral sphincter is closed or not, and if there is a cryptic hernia, it can be treated together to solve the problem at once. It is possible to investigate whether other congenital abdominal anomalies (such as umbilical cord, Meckel's diverticulum, etc.) are combined and treated together. 7.Q: What are the things to know related to laparoscopic surgery? A: No respiratory tract infection or other serious illnesses, elective surgery is sufficient. Laparoscopic surgery is minimally invasive and almost negligible. The total hospitalization period is 1-2 days. After the surgery, you can eat and drink normally after waking up from anesthesia, and there is no need to avoid eating. There is no restriction of activity and bed rest is not required. This is a clean procedure and does not require antibiotic treatment (anti-inflammatory).
