Shunt surgery during the era of liver transplantation.

OBJECTIVE: The indications for and the results of portosystemic shunts done in the authors' institution since initiation of a liver transplant program 10 years ago were reviewed. SUMMARY BACKGROUND DATA: With the widespread availability of liver transplantation as definitive treatment of chronic liver disease, the role of shunts in the overall management of variceal bleeding needs to be redefined. METHODS: Seventy-one variceal bleeders with cirrhosis who received a shunt (82% distal splenorenal shunts) because of sclerotherapy failure or because endoscopic treatment was not indicated were reviewed retrospectively. In 44 patients with well-preserved hepatic reserve, the shunt was used as a long-term bridge to transplantation (shunt group 1). The remaining 27 patients with shunts were not transplant candidates mainly because of uncontrolled alcoholism or advanced age (shunt group 2). Survival of both shunt groups was compared to that of 180 adult patients with a history of variceal bleeding who underwent transplantation soon after referral. RESULTS: Because of their more advanced liver disease, the liver transplant group had a higher operative mortality rate (19%) than did either of the shunt groups (5% and 7%, respectively) (p < 0.02). Kaplan-Meier survival analysis showed better survival in shunt group 1 (seven patients thus far transplanted) than in either the liver transplant group or shunt group 2 during the early years and superior survival of shunt group 1 and the liver transplant group as compared to shunt group 2 during the later years of the analysis. Only two patients from shunt group 1 have died of late postoperative hepatic failure without benefit of liver transplantation. CONCLUSIONS: A shunt may serve as an excellent long-term bridge to liver transplantation in patients with well-preserved hepatic reserve. Shunt surgery still plays an important role in treatment of selected patients with variceal bleeding who are not present or future transplant candidates.     

Liver Transplantation for Cystic Fibrosis in Adults

Purpose To expand our knowledge on liver transplantation for cirrhosis associated with cystic fibrosis in adults. Methods Five patients who underwent a liver transplantation due to cystic fibrosis were reviewed. The outcome of the patients in terms of age, immunosuppression regimen, patient and graft survival, and pre- and post-transplant complications were investigated. Results Five adult liver transplant patients had cystic fibrosis (0.2%). These included 4 men and 1 woman with a mean age of 31 ± 10, ranging from 22 to 52 years old at the time of transplantation. All patients had lung problems. Four patients had exocrine and two had endocrine pancreatic insufficiency. Two are currently alive with a follow-up of 5.8 years and 4 months after transplantation, respectively. There were three deaths from pulmonary embolism at 4.5 years, myocardial infarction with cyclosporine nephrotoxicity at 10.7 years, and lymphoproliferative disorder at 5 months after transplantation. No deaths occurred from lung infection. Only one patient had postoperative pulmonary infectious complications, which were successfully treated with antibiotics and did not result in mortality. Conclusion Adult liver transplantation for end-stage liver disease associated with cystic fibrosis offers encouraging results with a rapid general improvement after surgery and it is now considered to be a safe and acceptable treatment for this disease population.     

Combined Heart-Lung-Liver Transplantation for Patients With Cystic Fibrosis: The Australian Experience

BackgroundCombined multivisceral transplantation has emerged as a therapeutic option for a select patient cohort; however, clinical decision-making remains complex and controversial. The aim of this study was to examine patient characteristics, operative complications, and long-term outcomes of all patients who have undergone combined heart-lung-liver transplantation (HLLTx) in Australia.MethodsIn this study, we performed a retrospective analysis of all adult patients who have undergone combined HLLTx in Australia to date. Recipient clinical characteristics, waitlist, and transplant outcomes are described.ResultsEight adult patients have received HLLTx at a single Australian transplant center. Recipients of HLLTx have typically been young (median age, 30.1 years; range, 24-37), underweight (median body mass index, 19.8 kg/m²; range, 16.2-30.4) patients with cystic fibrosis (n = 8, 100%) with severe airflow obstruction (median forced expiratory volume in the first second of expiration, 24% predicted; range, 17%-48%) accompanied by liver cirrhosis confirmed on histopathology (n = 8, 100%). Despite relative preservation of synthetic function and low model for end-stage liver disease scores (median, 8; range, 6-17), all recipients had complications of portal hypertension prior to transplantation, with many patients having suffered life-threatening variceal hemorrhage. In this cohort, HLLTx was associated with overall posttransplant survival of 87.5% at 30 days, 71.4% at 1 year, and 42.9% at 5 years. Listing for combined HLLTx was associated with prolonged waitlist times relative to bilateral sequential single-lung transplantation (median 556 vs 56 days, respectively), however waitlist mortality and/or delisting was comparable between groups.ConclusionsTaken together, these findings highlight the opportunities and challenges facing combined (heart-) lung and liver transplantation in patients with multiorgan failure.     

Outcome of total splenectomy with portosystemic shunt for massive splenomegaly and variceal bleeding in cystic fibrosis

Multilobular biliary cirrhosis and portal hypertension are frequent complications of cystic fibrosis liver disease, leading to esophageal varices and splenomegaly. Therapy is focused on variceal bleeding control; however, reduction of spleen volume is also important to restore gastric volume and resolve invalidating abdominal discomfort. We report long-term follow up (median duration, 5.5 years; range, 14 months-21.5 years) of 6 patients with cystic fibrosis (4 men, 2 women; median age, 14 years; range, 8-18 years) who underwent splenectomy with a splenorenal shunt operation. Three patients received elective surgery for massive splenomegaly with important abdominal discomfort, recurrent variceal bleeding, and hypersplenism. Three were urgently treated to control variceal bleeding after several sessions of sclerotherapy. All but 2 received antipneumococcal vaccination before surgery. Four patients had a weight gain of 10% within 3 months of surgery, and 3 developed spontaneous puberty. Lung function remained stable, and there was an overall reduction of respiratory tract infections. The youngest patient, however, died of overwhelming septicemia during treatment with steroids. Although total splenectomy has important risks, in well-selected cases, it can have benefits. Immuno- and chemoprophylaxis, combined with patient awareness of supplementary risk of infections is indispensable to minimize septic complications.     

A single centre experience of liver disease in adults with cystic fibrosis 1995-2006.

BACKGROUND: Liver disease is an important cause of death in adults with cystic fibrosis (CF). Ursodeoxycholic acid (UDCA) may slow progression. Managing varices and timely evaluation for liver transplantation are important. METHODS: Adults with CF underwent annual review. Abnormalities of liver function tests or ultrasound prompted referral to the CF/liver clinic where UDCA was commenced. Endoscopic surveillance for varices was undertaken if ultrasound suggested portal hypertension. RESULTS: 154 patients were followed for a median 5 years. 43 had significant liver disease, 29 had cirrhosis with portal hypertension and 14 had ultrasound evidence of cirrhosis without portal hypertension. All started UDCA. Only one patient developed chronic liver failure and none required liver transplantation. 27 underwent endoscopy; 1 required variceal banding, the others had insignificant varices. Ultrasound was normal in 97 patients while five had steatosis; nine further patients had splenomegaly but no other evidence of portal hypertension. Neither spleen size nor platelet count correlated with portal hypertension. CONCLUSIONS: Liver disease was common in adults with CF but disease progression was rare. Thus liver disease detected and closely monitored in adults appeared to have a milder course than childhood CF. Splenomegaly, unrelated to portal hypertension may be a consequence of CF.     

Distal splenorenal shunt: preferred treatment for recurrent variceal hemorrhage in the patient with well-compensated cirrhosis

HYPOTHESIS: Distal splenorenal shunt (DSRS) is a safe and effective treatment for patients with Child-Pugh class A and B cirrhosis with recurrent variceal hemorrhage after failed transjugular intrahepatic portosystemic shunt. DESIGN: Retrospective case review. SETTING: Hepatobiliary surgery and liver transplantation department in a tertiary referral medical center. PATIENTS: Between August 1, 1985, and May 1, 2005, 119 patients with Child-Pugh class A and B cirrhosis underwent DSRS for recurrent variceal hemorrhage. Of these, 17 (14.3%) had thrombosed or failing transjugular intrahepatic portosystemic shunt prior to DSRS. INTERVENTION: Distal splenorenal shunt for recurrent variceal hemorrhage after failure of conservative management. MAIN OUTCOME MEASURES: Morbidity, mortality, and subsequent liver transplantation rate. RESULTS: The overall perioperative morbidity rate was 31.5%. Thirteen patients (11.7%) developed encephalopathy and 6 (5.4%) had recurrent variceal hemorrhage. Other complications included portal vein thrombosis, pancreatitis, pancreatic pseudocyst, pneumonia, and wound infection. The 30-day operative mortality rate was 6.4% (n = 7). The 1-year survival rate was 85.9%. The incidence of DSRS for failed transjugular intrahepatic portosystemic shunt during the first 12 years of the study (1985-1997) was 11.1% (9/81). This proportion increased to 26.7% (8/30) during the second half of the study (1997-2005). During the 20-year period, 15 patients (13.5%) underwent liver transplantation a mean of 5.1 years after DSRS without an increase in morbidity or mortality after transplantation. CONCLUSIONS: Distal splenorenal shunt may be the preferred treatment for recurrent variceal hemorrhage in the patient with well-compensated cirrhosis. In addition, DSRS does not cause increased morbidity or mortality in subsequent liver transplantation.     

Liver transplantation for variceal hemorrhage

At the present time, liver transplantation must be considered among the treatment options for patients with variceal hemorrhage. For a significant percentage of variceal bleeders throughout the world, however, transplantation is not a viable option either because the patient is not an appropriate transplant candidate or because of the etiology of the patient's portal hypertension. Sclerotherapy and portosystemic shunts remain the mainstay of therapy for these patients. The survival rates with liver transplantation are superior to those reported for other therapies for variceal hemorrhage in patients who have moderate or severe liver disease in addition to variceal hemorrhage. Child's C patients whose variceal hemorrhage is controlled medically should be evaluated for transplantation and receive chronic sclerotherapy while they wait on the transplant list. If the variceal hemorrhage cannot be controlled medically in a transplant candidate, then the patient should undergo an emergency shunt procedure. The shunt of choice is a large-bore H-graft mesocaval or mesorenal shunt. This shunt effectively controls the acute hemorrhage, is relatively simple to perform, does not adversely impact on the subsequent liver transplant, and can simply be ligated after the transplant is completed. Patients who experience variceal hemorrhage as the only manifestation of their liver disease should be treated initially with endoscopic sclerotherapy. For that small group of patients who are either not candidates for sclerotherapy or who rebleed despite sclerotherapy, the choice of shunt or transplantation is presently a difficult one, because both therapies provide excellent results in this group of patients. The choice of therapy should be made on an individual basis and only after consultation with both transplant and shunt surgeons. If a shunt is chosen, we prefer the DSRS because it maintains hepatic portal perfusion in many patients and does not require dissection of the porta hepatis. The management of patients with a prior portosystemic shunt at the time of transplantation depends on the type of shunt and the duration of time between the shunt and the transplant. Shunts not involving the hepatic hilum have little adverse impact on the performance of the transplant. There are insufficient data to assess accurately the effect of a prior portacaval shunt on the transplant. However, our clinical experience and that of other transplant groups indicate that the transplantation of these patients is technically more difficult than that of patients with shunts not involving the hilum. With the availability of other shunting procedures that do not involve extensive dissection of the hepatic hilum, there is little role for either end-to-side or side-to-side portacaval shunts in patients who are potential liver transplant candidates.(ABSTRACT TRUNCATED AT 400 WORDS)     

Bleeding esophageal varices: treatment by sclerotherapy and liver transplantation

Variceal hemorrhage is frequently a lethal event. Mortality among patients who have bled is high, with survival over the short term of only 25% to 50%. We retrospectively reviewed the records of 177 patients in whom variceal bleeding was treated with variceal sclerosis during a 5-year period from 1981 to 1986. All patients were treated by freehand injection of 25% sodium morrhuate with 35% dextrose, 4 ml per injection, through a fiberoptic endoscope. Of this group, 46 patients were treated with sclerosis followed by liver transplantation (group 1). These were compared to 36 nonalcoholic Child's class B and C patients treated with sclerosis alone (group 2). Survival at 4 years was poor in group 2 (17%). Liver failure and continued gastrointestinal bleeding were the most frequent causes of death. Survival among the liver-transplant group was significantly better (73%, p less than 0.001). Causes of death in this group were primarily due to sepsis, often in the setting of acute graft rejection. Group 1 patients were younger (39.8 +/- 10.8 vs 49.8 +/- 16.5 years, p less than 0.01); this difference is influenced by the deliberate selection of younger patients for liver transplantation. We conclude that sclerotherapy followed by liver transplantation significantly improves survival compared to conventional therapy in selected patients with advanced liver disease and portal hypertension. Donor organ availability will seriously limit the applicability of this approach to patients with bleeding esophageal varices.     

The surgeon''s role in the management of portal hypertension.

Patients with portal hypertension are referred to surgeons for several reasons. These include the management of continued active variceal bleeding; therapy after a variceal bleed to prevent further recurrent bleeds; consideration for prophylactic surgical therapy to prevent the first variceal bleed; or, rarely, an unusual cause of portal hypertension which may require some specific surgical therapy. Injection sclerotherapy is the most widely used treatment for both acute variceal bleeding and long-term management after a variceal bleed. Unfortunately it has probably been overused in the past. The need to identify the failures of sclerotherapy early and to treat them by other forms of major surgery is emphasized. The selective distal splenorenal shunt is the most widely used portosystemic shunt today, particularly in nonalcoholic cirrhotic patients. The standard portacaval shunt is still used for the management of acute variceal bleeding as well as for long-term management, particularly in alcoholic cirrhotic patients. For acute variceal bleeding the surgical alternative to sclerotherapy or shunting is simple staple-gun esophageal transection, whereas in long-term management the main alternative is an extensive devascularization and transection operation. Liver transplantation is the only therapy that cures both the portal hypertension and the underlying liver disease. All patients with cirrhosis and portal hypertension should be assessed as potential liver transplant recipients. If they are candidates for transplantation, sclerotherapy should be used to treat bleeding varices whenever possible, as this will interfere least with a subsequent liver transplant.     

Transjugular intrahepatic portosystemic shunt in non-cirrhotic portal hypertension related to cystic fibrosis in a lung transplant patient

Liver involvement is not uncommon in patients with cystic fibrosis (CF). Even if serious complications as non-cirrhotic portal hypertension, cirrhosis and liver failure rarely occur, they are associated with impaired survival and reduced quality of life. Herein, we have reported the first case of a patient with CF and non-cirrhotic portal hypertension who underwent transjugular intrahepatic portosystemic shunt placement for recurrent variceal bleeding after bilateral lung transplantation, and we have reviewed the available literature pertaining to this field.     

Heart and lung transplantation for terminal cystic fibrosis. A 4 1/2-year experience

From among 112 patients with cystic fibrosis who were assessed for heart-lung transplantation, 83 were accepted. Twenty-six died while awaiting heart-lung transplantation and 32 had the operation. The management and the outcome of these 32 patients is reported. Survival, infection, and rejection rates among these patients were compared with those of 61 patients without cystic fibrosis who underwent heart-lung transplantation between 1984 and 1990. The cumulative survival rate was 72.29% +/- 94.91% at 1 year and 55.59% +/- 7.50% at 3 years. The mortality rate was slightly higher in the group with cystic fibrosis during the first year after the operation but it was lower at 3 years. The difference, however, could have been due to chance alone (p = 0.308). The same was true for the prevalence of rejection (up to 6 months: chi 2 = 1.8141, p = 0.17), and infection (up to 6 months: chi 2 = 2.20, p = 0.14), between the two groups. It is concluded that cystic fibrosis does not constitute an additional risk in terms of survival and morbidity after heart-lung transplantation.     

Effects of liver transplantation on the nutritional status of patients with cystic fibrosis.

The long-term effects of liver transplantation on nutritional status, body composition and pulmonary function in patients with liver disease associated with cystic fibrosis (CF) are poorly defined. We studied 15 patients with CF-associated biliary cirrhosis and severe portal hypertension. Seven underwent liver transplantation (age: 14.8 +/- 6.2 years), and eight were treated conservatively (age: 15.9 +/- 6.7 years). All patients were evaluated at baseline and thereafter yearly for a median duration of 5 years. During follow-up, transplanted patients gained weight and showed a significant increment in body mass index (P < 0.004), whereas patients without transplantation remained stable (P = 0.063). Baseline bone mineral content (dual energy X-ray absorptiometry scan) was lower than normal in all patients (more in transplanted patients) and increased in transplanted patients (P < 0.05), but not in patients without transplantation. In both groups percent body fat did not change, whereas fat free mass increased only in the transplant group (P = 0.06) (P < 0.03 versus nontransplanted patients). Only in transplanted patients' plasma concentrations of vitamin E and A increased (P < 0.05 versus nontransplanted patients). Forced espiratory volume in 1 s and forced vital capacity showed similar deterioration in transplanted and in nontransplanted patients. Liver transplantation is associated with long-term beneficial effects on the nutritional status of CF patients and seems to favor bone mineralization.     

Outcomes of patients with cystic fibrosis undergoing lung transplantation with and without cystic fibrosis-associated liver cirrhosis

People with severe cystic fibrosis (CF) lung disease with co-existent CF-associated liver disease (CFLD) are often excluded from consideration of sole lung transplantation, largely because of the concerns that they will subsequently develop hepatic decompensation. This retrospective cohort study aimed at determining whether patients with severe cirrhosis caused by CFLD have any differences in perioperative and relevant post-transplant outcomes compared to CF patients without CFLD when undergoing sole lung transplantation. Six patients with CFLD were matched with 18 CF patients without CFLD undergoing sole lung transplant at the same institution. There were no differences in total operative time or intra-operative requirements for cardiopulmonary bypass or blood products. Over a period of five yr post-transplant, no differences were observed between the two groups in body mass index, six-min walk, lung function, and survival. None of the CFLD subjects developed variceal bleeding; however, one developed hepatocellular and renal failure at four yr post-transplant and is being assessed for liver-kidney transplant. One additional patient with CFLD required repeat lung transplantation for bronchiolitis obliterans syndrome. This study provides evidence that CF patients with liver cirrhosis caused by CFLD can safely be considered for sole lung transplantation provided there is no evidence of significant hepatocellular dysfunction with decompensated cirrhosis or hepatic synthetic failure.     

Distal splenorenal shunt: role, indications, and utility in the era of liver transplantation

HYPOTHESIS: The distal splenorenal shunt (DSRS) continues to play an important role in the management of recurrent variceal bleeding with minimal negative impact on subsequent orthotopic liver transplantation (OLT). DESIGN: Case-control study. SETTING: Hepatobiliary surgery and liver transplantation unit in a tertiary referral medical center. PATIENTS: From August 1, 1985, through October 31, 1997, a single team of surgeons performed 81 DSRS procedures for recurrent variceal hemorrhage. Eleven patients undergoing OLT subsequent to DSRS were compared with a group of 274 patients undergoing OLT without any previous shunt during the same period. MAIN OUTCOME MEASURES: Operative time, use of blood products, length of hospital stay, perioperative complications, and survival rates. RESULTS: Operative (30-day) mortality for DSRS was 6% (n = 5). From follow-up information available for 74 patients, the 1- and 5-year survival rates were 86.4% (n = 64) and 74.3% (n = 55), respectively. Recurrent variceal bleeding and hepatic encephalopathy occurred in 5 (6.8%) and 11 patients (14.9%), respectively, after DSRS. In 9 patients, DSRS was used as salvage for failed transjugular intrahepatic portosystemic shunt. CONCLUSIONS: Distal splenorenal shunt is a safe, durable, and effective treatment for controlling recurrent variceal hemorrhage in patients with acceptable operative risk and good liver function. It does not compromise future liver transplantation and can considerably delay the time until transplantation is required. Given the early occlusion rate and need for constant surveillance, transjugular intrahepatic portosystemic shunting should be reserved for patients with Child C classification cirrhosis with chronic hemorrhage or intractable ascites or as an emergency procedure for patients with uncontrollable bleeding using endoscopic therapy.     

Cystic fibrosis. Target population for lung transplantation in North America in the 1990s.

Cystic fibrosis is the most common lethal genetic disease occurring in the white population. It is estimated that 3.5% of the 20,000 individuals with cystic fibrosis in North America will die each year of end-stage lung disease. Lung transplantation (heart-lung or double lung) is becoming more frequent as more patients are referred for this procedure. Since January 1988, we have evaluated 60 patients with cystic fibrosis for lung transplantation and have accepted 30 (50%). Nine patients (30%) died while awaiting a donor. Fifteen patients underwent transplantation (13 heart-lung and two double lung procedures). Actuarial survival at 1, 2, and 3 years is 76%. All survivors are without physical limitations. Pulmonary function, as determined by forced vital capacity, forced expiratory volume in 1 second, and arterial blood gas determinations, is within the normal range. Comparing these data with those of a group of patients without cystic fibrosis who underwent transplantation during the same period did not reveal any significant differences with respect to infection, rejection, and outcome. Preliminary data suggest that obliterative bronchiolitis is less prevalent at 1 year in patients with cystic fibrosis (19%) than in those without cystic fibrosis (41%). Patients with cystic fibrosis present a number of challenges. The problems of pleural adhesions from repeated infections, pleurodesis, and previous thoracic procedures are now readily approached through the bilateral thoracosternotomy (clam shell) incision. Insulin-dependent diabetes mellitus and low-dose corticosteroid therapy are no longer considered absolute contraindications. Both septic lungs must be removed at operation, either with heart-lung transplantation or with double lung transplantation. These data support the therapeutic efficacy of lung transplantation for patients with cystic fibrosis.     

Esophageal endosclerosis in children

During the past 6 years, 25 consecutive patients with esophageal variceal hemorrhage were treated by esophageal endosclerosis (direct injection of varices with a sclerosing agent). The primary disease in the 25 children was portal vein thrombosis (11 patients), biliary atresia (nine patients), and hepatic cirrhosis from cystic fibrosis (three patients), alpha 1-antitrypsin deficiency (one patient), and neonatal hepatitis (one patient). Thirteen patients were treated during acute, major variceal hemorrhage. Esophageal endosclerosis was repeated at regular intervals until all esophageal varices were obliterated. Twenty-one patients completed therapy. Four patients died: one of a complication of therapy and three of the primary disease. Other than the one death, complications were minor. Recurrent esophageal variceal hemorrhage has not been encountered in follow-up from 9 months to 6 years after completion of therapy.     

Endoscopic sclerotherapy in acute variceal hemorrhage

Acute variceal hemorrhage in patients with alcoholic cirrhosis and poor liver function is associated with a high mortality. A nonoperative treatment, endoscopic sclerotherapy, was employed in 22 patients with cirrhosis and poor liver function who had 24 episodes of acute variceal hemorrhage over a 20 month period. Portal hypertension was secondary to alcoholic cirrhosis in 21 patients and cystic fibrosis in 1 patient. Of the 24 patient admissions, 21 were of patients in Child's class C and 3 were class B. Endoscopic sclerotherapy was performed under endotracheal general anesthesia using a modified Negus rigid esophagoscope. The sclerosant (5 percent sodium morrhuate) was injected into all visible varices near the gastroesophageal junction using a MacBeth needle. Definitive control of variceal hemorrhage for the entire hospitalization was achieved in 19 of 24 admissions (79 percent). The in-hospital mortality for acute variceal bleeding was 29 percent; 81 percent of the patients were discharged after control of hemorrhage. There were two major and five minor complications related to sclerotherapy. Based on this preliminary experience it is concluded that injection sclerotherapy controls bleeding and reduces mortality associated with acute variceal hemorrhage in patients with poor liver function.     

Sclerotherapy of esophageal varices: long-term results and determinants of survival

Between 1980 and 1986, 177 patients underwent sclerotherapy by means of the flexible fiberoptic endoscope for bleeding esophageal varices. Of these, 129 were treated with serial sclerotherapy alone. The remaining 48 patients underwent liver transplantation after sclerotherapy; these are reported separately. Patients were classified by Child's criteria, by the severity of the initial bleeding episode as reflected by the urgency of treatment, and by the nature of the underlying liver disease. Long-term survival rates were markedly influenced by Child's classification, with 83% of the patients in class A, 45% of those in class B, and 20% of those in class C surviving beyond 36 months (p less than 0.001). Urgent treatment was associated with a poorer survival than was elective treatment (p less than 0.001). Survival was not influenced by underlying alcoholic liver disease as compared to a nonalcoholic liver disease. The majority of deaths occurred within the first 100 days after the initial treatment. Child's class B and C patients had the highest early mortality rates, particularly in an acute treatment setting. The most frequent causes of death included progressive liver failure and persistent hemorrhage. Sclerotherapy for bleeding esophageal varices may successfully control hemorrhage, but the influence of this treatment on long-term survival is limited. Hepatic reserve, indicated by Child's classification, is the major determinant of survival. Significant improvements in survival after variceal bleeding are intimately linked to improvement in liver function.     

Selective operative approach for variceal hemorrhage

Since 1978, the operation chosen for patients with variceal hemorrhage has been based on preoperative hemodynamic and clinical factors. One hundred sixteen consecutive patients were managed with the following operations: distal splenorenal shunt (75 patients), nonselective shunts (33 patients), and nonshunting operation (8 patients). Emergency surgery was required in 19 percent of patients. The selection criteria used resulted in the majority of high risk patients receiving nonselective shunts. This selective operative approach resulted in an overall operative mortality of 12 percent, a median survival of 3 years, and postoperative encephalopathy, ascites, and recurrent variceal hemorrhage in 20, 23, and 11 percent of patients, respectively. Operative mortality for the total group was closely related to Child's class. Whereas encephalopathy was most frequent after nonselective shunts, ascites was more common after the distal splenorenal shunt. Recurrent hemorrhage rarely occurred after a shunting procedure, but was a frequent complication of nonshunting operations. Neither the type of procedure selected nor the cause of liver disease influenced long-term survival.     

Definitive therapy for variceal bleeding: a personal view

Definitive therapy for variceal hemorrhage has evolved during the past half century. Only completely decompressing shunts (nonselective shunts) were available before 1967. Additional options now include selective shunts, devascularization procedures, endoscopic sclerotherapy, pharmacotherapy, and hepatic transplantation. Although drug treatment is experimental at the present time, the remaining therapeutic options are applicable to various subgroups of patients and in certain clinical settings. At the University of Nebraska, patients with variceal bleeding are first grouped based on their candidacy for transplantation. Transplantation candidates with advanced (Child's class C) or symptomatic liver disease undergo transplantation as soon as possible. Future transplantation candidates with stable, asymptomatic liver disease undergo either long-term sclerotherapy or a distal splenorenal shunt if sclerotherapy fails or if they have poor access to tertiary medical care. These patients are carefully monitored so that they can undergo transplantation before they become high-operative risks. Patients who are not candidates for transplantation receive chronic variceal sclerotherapy as initial therapy so long as shunt surgery is readily available if sclerotherapy fails. When surgery is indicated, the distal splenorenal shunt is preferred to nonselective shunts because several controlled and uncontrolled series have demonstrated a lower frequency of encephalopathy after selective variceal decompression.
