Management of the cirrhotic patient that needs surgery.
Conditions that necessitate surgery frequently arise in patients with chronic liver disease and cirrhosis. Because cirrhosis has the ability to cause physiologic derangements in every organ system in the body, clinicians face significant challenges in preoperative preparation of the patient with cirrhosis in order to decrease postoperative morbidity and mortality. Emergent operations add an extra dimension of complexity to the clinical picture, due to limited preoperative time to prepare the patient with cirrhosis for surgery. In cases of severely decompensated cirrhosis, clinicians should have in their armamentarium possible alternatives to surgery that can be used to temporize the emergent nature of the disease and improve patient outcomes. The classification of cirrhotic liver disease by Child and Turcotte was initially utilized to predict mortality in patients undergoing surgically placed shunts for portal hypertensive bleeding. Subsequent studies have pointed to the fact that other general and thoracic surgery procedures can be assigned predicted mortality rates according to a similar classification scheme, the modified Child-Pugh score. Patients with cirrhosis facing surgery should undergo a careful history and physical examination and should be accurately placed into a designated Child-Pugh category. Because the modified Child-Pugh class is the most reliable determinant of postoperative morbidity and mortality, every attempt should be made to upgrade a patient's class in a favorable direction prior to surgery. Patients should be carefully evaluated for the presence of ascites and dietary alterations. In addition, medical management with diuretics should be employed to prevent postoperative ascites leak and possible infectious complications including bacterial peritonitis. Perhaps one of the most feared complications in the patient with cirrhosis facing surgery is hemorrhage. Because the liver is vital in maintenance of coagulation homeostasis, several pharmacologic adjuncts may be administered to correct any coagulopathy in the peri-operative period. Several diseases such as cholelithiasis and peptic ulcer disease are known to be more prevalent in the cirrhotic patient, and clinicians treating these diseases should have a thorough understanding of the pathophysiology of cirrhosis and portal hypertension. Patients with cirrhosis and portal hypertensive bleeding that are considered good surgical candidates (ie, Child-Pugh class A) may benefit from surgical portasystemic shunt in contrast to angiographically placed portacaval shunt (ie, transjugular intrahepatic portosystemic shunt ) due to the lack of durable patency and cost effectiveness in the latter. In patients with cirrhosis awaiting orthotopic liver transplantation, TIPS may be a lifesaving temporizing technique that is utilized as a bridge to transplantation.
