hilar cholecysto anastomosis

Hepatic hilar anastomosis for the surgical treatment of inoperable orthostatic bile duct atresia. Congenital biliary atresia is a congenital or partial atresia or absence of the bile duct system. The cause is still unclear and may be the result of cholecystectomy in embryonic development. In recent years, some people think that this disease is closely related to neonatal hepatitis. Both can exist at the same time, or first develop into bile duct atresia for giant cell hepatitis. It is also believed that due to infectious, vascular or chemical causes of the embryo, the bile duct system is harmed, and the bile duct is occluded, hardened or partially disappeared. This course of disease can continue from the time of embryonic development to the time of birth. Bile duct atresia can be divided into intrahepatic type and extrahepatic type, in which intrahepatic type is intrahepatic bile duct system atresia, there are only irregular small bile ducts in the liver with stenosis or atresia, and there is no good treatment method; extrahepatic bile duct The lock can be divided into VI type according to the position of the lock. Among them, type I-III is a type, accounting for 80%-90% of extrahepatic bile duct atresia, which is called non-correctable type; type IV-VI is another type, which can be corrected, with a good prognosis, accounting for about 10%~ 20%. Treatment of diseases: cholangitis stenosis Indication Hepatic hilar anastomosis is suitable for patients with hepatic duct atresia, GrossI type and Kasai type III with gallbladder, cystic duct and common bile duct. Surgical procedure 1. Open laparotomy, clearly defined as type 1 extrahepatic biliary atresia, cut the hepatoduodual ligament along the upper edge of the duodenum, and properly protect the gallbladder and common bile duct. The fibrous connective tissue of the hepatic portal was removed in one piece and separated into the hepatic hilum 1 cm deep. Protect the portal vein and hepatic artery. With the liver portal jejunostomy. 2. The gallbladder artery is preserved, the gallbladder is released from the gallbladder bed, and then the bottom of the gallbladder is reversed to the hepatic hilum, and the connective tissue of the hepatic portal is spliced to the sarcoplasmic layer. The gallbladder was incised 1 cm, and the posterior margin of the gallbladder and the fibrous tissue of the hepatic portal was sutured by 2-0 silk suture. The same method was used to match the anterior wall. complication 1. Hepatic damage is aggravated In children with extrahepatic biliary atresia, such as failure to effectively relieve biliary obstruction during surgery, postoperative jaundice will gradually deepen, and cirrhosis and liver function damage will continue to increase. Sometimes complications such as hepatic coma, ascites, and upper gastrointestinal bleeding are combined, which is the main cause of death in sick children. 2. Anastomotic opening It is a serious complication. The reason for the occurrence is that there is local tension after the anastomosis, which affects the blood vessel to cause cracking; in addition, due to the small field of view and the depth of the operation, it is often impossible to satisfactorily perform the inversion suture. In addition, the children with high jaundice, liver dysfunction, hypoproteinemia have a certain degree of impact on healing. When the anastomosis is ruptured, the sick child often has a sudden high fever and increased drainage. The method of treatment is to fully drain, strengthen the supportive therapy, wait for it to heal itself or form a chronic sinus, and elective fistula resection. 3. Incision cracking Often occurs within 5 to 10 days after surgery. The main cause is abdominal distension, severe liver damage, malnutrition, ascites, abdominal or incisional infection. The clinical manifestation is that a large amount of bloody exudate suddenly flows out of the early wound. In severe cases, the incision suture cuts the skin, and the internal organs (mainly the small intestine) come out of the incision. When the incision is opened, the intestine should be immediately removed to the operating room for suturing the incision under general anesthesia. If necessary, the suture should be sutured, and anti-infection and supportive therapy should be strengthened after surgery. 4. Ascending cholangitis This is another serious complication after hepaticojejunostomy. Clinical manifestations of high fever, deepening of jaundice, white stool, high mortality. In the hepatic portal anastomosis, the distal end of the jejunum is made into a stoma, which can greatly reduce the occurrence of reflux and ascending cholangitis. Other authors have made a series of improvements to prevent reflux, such as rectangular petals, intussusception, artificial nipple anti-reflux, etc., can play a different degree of anti-reflux. It is suggested that when reflux cholangitis and jaundice are deepened after hilar jejunostomy, the anastomosis should be re-explored and the anastomotic obstruction should be relieved in time to reduce death and regain bile flow.
