Intestinal obstruction in children
Pediatric intestinal obstruction refers to the blockage of intestinal contents within the intestine due to various causes. According to the etiology, it is classified into mechanical intestinal obstruction, dynamic intestinal obstruction, and vascular intestinal obstruction. The main symptoms include abdominal pain, vomiting, and abdominal distension.
View detailsHydrocele
Hydrocele refers to a cystic lesion formed by excessive accumulation of fluid in the testicular tunica vaginalis cavity, exceeding the normal volume. This condition can occur at any stage but is more common in children. When the amount of fluid in the tunica vaginalis is not large, there are usually no symptoms, and it is often discovered incidentally during bathing or physical examinations. When a large amount of fluid leads to a significant increase in the size or tension of the scrotal mass, a sensation of scrotal heaviness may occur.

Congenital hemangiomas are vascular tumors present at birth, a common group of diseases in the neonatal period, formed by the proliferation of angioblastic cells during embryonic development. The incidence rate is less than 3% among all hemangiomas, with a male-to-female ratio close to 1:1. Lesions are commonly found in the head, face, and limbs, mostly solitary, but occasionally multiple.
Infantile hemangioma
Infantile hemangioma is a benign proliferative disease of vascular endothelial cells and is the most common tumor in childhood. It usually appears around 1 week after birth, with the head and neck being the most common sites.

Pediatric hydronephrosis is a condition where urine cannot drain normally from the kidney to the bladder, leading to its accumulation in the kidney and causing swelling in one or both kidneys. In pediatric patients, hydronephrosis can be detected during infancy, and even prenatally during ultrasound examinations before the baby is born.

Cryptorchidism refers to the condition where one or both testes fail to descend into the scrotum at birth. This condition is more common in premature infants. The main symptoms include unilateral or bilateral empty scrotum with no palpable testes.

Congenital megacolon, also known as Hirschsprung's disease, is a common congenital intestinal motility disorder with an incidence of approximately 1/5000, affecting more male infants than female infants. Due to the lack of nerve cells controlling the distal colorectum, normal peristalsis and defecation are impaired, leading to constipation, obstruction, and abdominal distension in infants and young children. As feces accumulate in the intestines, it can cause severe harm to the infant's body, leading to severe infections or malnutrition.
View detailsPediatric hernia
Pediatric hernia refers to a condition where an organ or tissue in the human body leaves its normal position and enters another area through a congenital or acquired weak point, defect, or opening, causing symptoms. Most pediatric hernias appear when the child is 2-3 months old, but some may occur as late as 1-2 years of age. The main manifestation is a variable-sized, changing mass in the inguinal region or umbilical opening. The mass may enlarge when the child coughs, cries, or strains. In the early stages, the mass often disappears spontaneously after lying down or stopping crying, or it can be reduced by manual pressure.
