Temporary Portocaval Shunt Provides Superior Intraoperative Hemodynamics and Reduces Blood Loss and Duration of Surgery in Live Donor Liver Transplantation: A Randomized Control Trial. Ann Surg 2024; 279:932-944. [PMID: 38214167 DOI: 10.1097/sla.0000000000006200] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2023] [Accepted: 01/04/2024] [Indexed: 01/13/2024]
Abstract
OBJECTIVE To compare intraoperative hemodynamic parameters, blood loss, renal function, and duration of surgery with and without temporary portocaval shunt (TPCS) in live donor liver transplantation (LT) recipients. Secondary objectives were postoperative early graft dysfunction, morbidity, mortality, total intensive care unit, and hospital stay. BACKGROUND Blood loss during recipient hepatectomy for LT remains a major concern. Routine use of TPCS during LT is not yet elucidated. METHODS This study is a single-center, open-label, randomized control trial. The sample size was calculated based on intraoperative blood loss. After exclusion, a total of 60 patients, 30 in each arm (TPCS vs no TPCS) were recruited in the trial. RESULTS The baseline recipient and donor characteristics were comparable between the groups. The median intraoperative blood loss ( P = 0.004) and blood product transfusions ( P < 0.05) were significantly less in the TPCS group. The TPCS group had significantly improved intraoperative hemodynamics in the anhepatic phase as compared with the no TPCS group ( P < 0.0001), requiring significantly less vasopressor support. This led to significantly better renal function as evidenced by higher intraoperative urine output in the TPCS group ( P = 0.002). Because of technical simplicity, the TPCS group had significantly fewer inferior vena cava injuries (3.3 vs 26.7%, P = 0.026) and substantially shorter hepatectomy time and total duration of surgery (529.4 ± 35.54 vs 606.83 ± 48.13 min, P < 0.0001). The time taken for normalization of lactate in the immediate postoperative period was significantly shorter in the TPCS group (median, 6 vs 13 h; P = 0.04). Although postoperative endotoxemia, major morbidity, 90-day mortality, total intensive care unit, and hospital stay were comparable between both groups, tolerance to enteral feed was earlier in the TPCS group. CONCLUSIONS In live donor LT, TPCS is a simple and effective technique that provides superior intraoperative hemodynamics and reduces blood loss and duration of surgery.

Which cava anastomotic techniques are optimal regarding immediate and short-term outcomes after liver transplantation: A systematic review of the literature and expert panel recommendations. Clin Transplant 2022; 36:e14681.

Abstract
BACKGROUND It has long been debated whether cava anastomosis should be performed with the piggyback technique or cava replacement, with or without veno-venous bypass (VVB), with or without temporary portocaval shunt (PCS) in the setting of liver transplantation. OBJECTIVES To identify whether different cava anastomotic techniques and other maneuvers benefit the recipient regarding short-term outcomes and to provide international expert panel recommendations. DATA SOURCES Ovid MEDLINE, Embase, Scopus, Google Scholar, and Cochrane Central. METHODS A systematic review following PRISMA guidelines and recommendations using the GRADE approach derived from an international expert panel (CRD42021240979). RESULTS Of 3205 records screened, 307 publications underwent full-text assessment for eligibility and 47 were included in qualitative synthesis. Four studies were randomized control trials. Eighteen studies were comparative. The remaining 25 were single-center retrospective noncomparative studies. CONCLUSION Based on existing data and expert opinion, the panel cannot recommend one cava reconstruction technique over another, rather the surgical approach should be based on surgeon preference and center dependent, with special consideration toward patient circumstances (Quality of evidence: Low | Grade of Recommendation: Strong). The panel recommends against routine use of vevo-venous bypass (Quality of evidence: Very Low | Grade of Recommendation: Strong) and against the routine use of temporary porto-caval shunt (Quality of evidence: Very Low | Grade of Recommendation: Strong).

Abstract
BACKGROUND To evaluate the significance of portosystemic shunts and associated long-term outcomes in living donor liver transplant (LDLT) among pediatric patients. METHODS Retrospective review of 121 pediatric patients who underwent LDLT between May 1994 and December 2015 at Taiwan Kaohsiung Chang Gung Memorial Hospital. Pre- and postoperative computed tomography images of the liver were reviewed, and portal vein complications were assessed. RESULTS Ninety-seven pediatric patients were included in the study, and 70 had portosystemic shunts before transplant. Thirty-three patients have portal systemic shunt (PSS) 6 months after transplant (mean [SD] shunt size, 4.59 [1.98] mm). Thirty-seven patients' portosystemic shunts closed spontaneously (mean [SD] shunt size, 3.14 [1.06] mm). Smaller PSSs tend to close spontaneously with a cutoff point of 3.35 mm by receiver operating characteristic curve (P = .01). Patients with PSS have more portal vein complications than those without PSS (44.3% vs 11.1%, P = .02). Among PSS recipients, patients with portal vein complications tend to have larger PSS size (mean [SD], 4.14 [1.96] mm vs 3.59 [1.48] mm), although the difference is not statistically significant (P = .19). CONCLUSIONS In pediatric patients, preoperative portosystemic shunts are significantly correlated with portal venous complications, some of which require minimal interventions after LDLT with good outcomes. Shunts larger than 3.35 mm tend to persist after transplant with increased portal venous complications.

Friend or Foe? Spontaneous Portosystemic Shunts in Cirrhosis-Current Understanding and Future Prospects. Can J Gastroenterol Hepatol 2021; 2021:8795115.

Abstract
Portal hypertension (PHT) in cirrhosis results from increased resistance to splanchnic blood flow secondary to parenchymal and vascular changes within the liver. In an attempt to counteract the increased portal pressure, two mechanisms simultaneously occur: splanchnic vasodilatation and formation of spontaneous portosystemic shunts (SPSS). Long considered to be a compensatory mechanism to decompress the portal venous system, it is now well established that SPSS are not only inefficient in decreasing the portal pressure but also contribute to reduced hepatocyte perfusion and increased splanchnic blood flow and resistance, associated with worsening PHT. Recent studies have described a high prevalence of SPSS in cirrhosis patients, increasing with liver dysfunction, and observed an association between the presence of SPSS and worse clinical outcomes. In cirrhosis patients with preserved liver functions, the presence of SPSS independently increases the risk of hepatic encephalopathy, variceal bleeding, and ascites, and reduces transplant-free survival. Moreover, the presence of SPSS in patients undergoing transjugular intrahepatic portosystemic shunting and liver transplant has been shown to variably affect the postprocedural outcome. This article provides an overview of the current understanding of the role of SPSS in the natural history of liver cirrhosis and their status as a therapeutic target and an imaging biomarker to identify patients at higher risk of developing complications of PHT.

Abstract
Portal hypertension is the main consequence of liver cirrhosis, leading to severe complications such as variceal hemorrhage, ascites or hepatic encephalopathy. As an attempt to decompress the portal venous system, portal flow is derived into the systemic venous system through spontaneous portosystemic shunts (SPSSs), bypassing the liver. In this review, we aim to provide an overview of the published reports in relation to the prevalence and physiopathology behind the appearance of SPSS in liver cirrhosis, as well as the complications derived from its formation and its management. The role of SPSS embolization is specifically discussed, as SPSSs have been assessed as a therapeutic target, mainly for patients with recurrent/persistent hepatic encephalopathy and preserved liver function. Furthermore, different aspects of the role of SPSS in liver transplantation, as well as in candidates for transjugular intrahepatic portosystemic shunt are reviewed. In these settings, SPSS occlusion has been proposed to minimize possible deleterious effects, but results are so far inconclusive.

Abstract
The management of large spontaneous portosystemic shunt (SPSS) during liver transplantation (LT) is a matter of debate. The aim of this study is to compare the short-term and longterm outcomes of SPSS ligation versus nonligation during LT, when both options are available. From 2011 to 2017, 66 patients with SPSS underwent LT: 56 without and 10 with portal vein thrombosis (PVT), all of whom underwent successful thrombectomy and could have portoportal reconstruction. The SPSS were either splenorenal (n = 40; 60.6%), left gastric (n = 16; 24.2%), or mesenterico-iliac (n = 10; 15.1%). Following portoportal anastomosis, the SPSS was ligated in 36 (54.4%) patients and left in place in 30 (45.5%) patients, based on the effect of the SPSS clamping/unclamping test on portal vein flow during the anhepatic phase. Intraoperatively, satisfactory portal flow was obtained in both groups. Primary nonfunction (PNF) and primary dysfunction (PDF) rates did not differ significantly between the 2 groups. Nonligation of SPSS was significantly associated with a higher rate of postoperative encephalopathy (P < 0.001) and major postoperative morbidity (P = 0.02). PVT occurred in 0 and 3 patients in the ligated and nonligated shunt group, respectively (P = 0.08). A composite end point, which included the relevant complications in the setting of SPSS in LT (ie, PNF and PDF, PVT, and encephalopathy) was present in 16 (44.4%) and 22 (73.3%) patients of the ligated and nonligated shunt group, respectively (P = 0.02). Patient (P = 0.05) and graft (P = 0.02) survival rates were better in the ligated shunt group. In conclusion, the present study supports routine ligation of large SPSS during LT whenever feasible.

Abstract
BACKGROUND The value of temporary intraoperative porto-caval shunts (TPCS) in cava-sparing liver transplantation is discussed controversially. Aim of this meta-analysis was to analyze the impact of temporary intraoperative porto-caval shunts on liver injury, primary non-function, time of surgery, transfusion of blood products and length of hospital stay in cava-sparing liver transplantation. METHODS A systematic search of MEDLINE/PubMed, EMBASE and PsycINFO retrieved a total of 909 articles, of which six articles were included. The combined effect size and 95 % confidence interval were calculated for each outcome by applying the inverse variance weighting method. Tests for heterogeneity (I 2) were also utilized. RESULTS Usage of a TPCS was associated with significantly decreased AST values, significantly fewer transfusions of packed red blood cells and improved postoperative renal function. There were no statistically significant differences in primary graft non-function, length of hospital stay or duration of surgery. CONCLUSION This meta-analysis found that temporary intraoperative porto-caval shunts in cava-sparing liver transplantation reduce blood loss as well as hepatic injury and enhance postoperative renal function without prolonging operative time. Randomized controlled trials investigating the use of temporary intraoperative porto-caval shunts are needed to confirm these findings.

Abstract
During orthotopic liver transplantation (OLT), clamping of the portal vein induces splanchnic venous congestion and accumulation of noxious compounds. These adverse effects could increase ischemia/reperfusion injury and subsequently the risk of graft dysfunction, especially for grafts harvested from extended criteria donors (ECDs). Temporary portocaval shunt (TPCS) could prevent these complications. Between 2002 and 2013, all OLTs performed in our center were retrospectively analyzed and a propensity score matching analysis was used to compare the effect of TPCS in 686 patients (343 in each group). Patients in the TPCS group required fewer intraoperative transfusions (median number of packed red blood cells-5 versus 6; P = 0.02; median number of fresh frozen plasma-5 versus 6; P = 0.02); had improvement of postoperative biological parameters (prothrombin time, Factor V, international normalized ratio, alkaline phosphatase, and gamma-glutamyltransferase levels); and showed significant reduction of biliary complications (4.7% versus 10.2%; P = 0.006). Survival analysis revealed that TPCS improved 3-month graft survival (94.2% versus 88.6%; P = 0.01) as well as longterm survival of elderly (ie, age > 70 years) donor grafts (P = 0.02). In conclusion, the use of TPCS should be recommended especially when considering an ECD graft. Liver Transplantation 23 174-183 2017 AASLD.

Abstract
INTRODUCTION Liver transplantation is the best therapeutic option for end-stage liver disease. Non-selective beta-blocker medications such as propranolol act directly on the cardiovascular system and are often used in the prevention of gastrointestinal bleeding resulting from HP. The effects of propranolol on cardiovascular system of cirrhotic patients during liver transplantation are not known. OBJECTIVE Evaluate the influence of propranolol used preoperatively on cardiac index during the anhepatic phase of liver transplantation. METHOD 101 adult patients (73 male [72.2%]) who underwent cadaveric donor orthotopic liver transplantation by piggyback technique with preservation of the retrohepatic inferior vena cava performed at Hospital das Clinicas, Federal University of Minas Gerais were evaluated. There was no difference in severity between groups by the MELD system, p=0.70. The preoperative use of propranolol and the cardiac index outcome were compared during the anhepatic phase of liver transplantation in 5 groups (I: increased cardiac index, II: cardiac index reduction lower than 16%, III: cardiac index reduction equal to or greater than 16% and less than 31%, IV: cardiac index reduction equal to or greater than 31% and less than 46%, V: cardiac index reduction equal to or greater than 46%). RESULTS Patients in group I (46.4%) who received propranolol preoperatively were statistically similar to groups II (60%), III (72.7%), IV (50%) and V (30.8%), p=0.57. CONCLUSION The use of propranolol before transplantation as prophylaxis for gastrointestinal bleeding may be considered safe, as it was not associated with worsening of cardiac index in anhepatic phase of liver transplantation.

Abstract
OBJECTIVE Our objective was to perform a retrospective study that described the anastomosis technique as well as the complications of side-to-side cavo-caval reconstruction. PATIENTS AND METHODS From June 1998 to April 2011, we performed 284 liver transplantations including 10 adults with live donor organs. In all cases but 2 (272), cavo-caval reconstruction was performed using side-to-side cavo-caval (STSCC) anastomosis. In 19 cases (6.9%), we also carried out an end-to-side temporary porto-caval shunt (TPCS). In 17 cases (6.2%) the technique was performed for retransplantation. RESULTS STSCC anastomosis was technically feasible in all but 2 cases, regardless of the recipient's vena cava, anatomic factors, or graft size. Mean operative time for the STSCC was 13 minutes (range, 6-25). Routine Doppler ultrasonography was performed intraoperatively at the end of the surgery. There was no case of cava stump thrombosis. Complications associated with this technique were limited to 2 patients. One complication was torsion due to donor graft/recipient mismatch, which was successfully treated surgically by falciform ligament fixation. The second complication was only evident by sinusoidal congestion and was managed nonoperatively. Seventeen cases were uneventful for retransplant recipients. CONCLUSIONS STSCC during piggyback liver transplantation is safe and can be performed in the retransplantation setting, with a low incidence of venous outflow obstruction that can be associated with the traditional piggyback technique. Our data suggest that donor graft to recipient mismatch is not an absolute contraindication when proper body size match is considered. A wide anastomosis with typical recipient hepatic vein inclusion is warranted with routine postanastomotic Doppler ultrasonography.

Temporary intraoperative porto-caval shunt: useless or beneficial in piggy back liver transplantation? Transpl Int 2012; 26:90-8. [PMID: 23237579 DOI: 10.1111/tri.12007] [Citation(s) in RCA: 31] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2012] [Revised: 07/21/2012] [Accepted: 10/07/2012] [Indexed: 12/26/2022]
Abstract
The role of intraoperative porto-caval shunts in orthotopic liver transplantation (OLT) is controversial. Aim of this study was to analyze the effects of an intraoperative, porto-caval catheter-shunt on graft function and survival following cava sparing OLT. Four hundred and forty-eight piggy back liver transplantations with or without a temporary spontaneous porto-caval shunt between 1997 and 2010 were analyzed (shunt n = 274 vs. no shunt n = 174). Lab MELD scores and donor risk indices (DRI) were calculated. Hepatic injury (ALT, AST), -function (bilirubin, prothrombin ratio), postreperfusion liver blood flow and graft survival were registered [mean follow-up: 50.5 (0-163.0) months]. The impact of a shunt on graft survival was determined using multivariate analysis. Usage of a porto-caval shunt was associated with reduced hepatic injury (ALT, AST), whereas graft function was not affected. The shunt group showed a significantly increased portal venous blood flow after reperfusion. Retransplantation rate was decreased (7.7% vs. 20.1%, P = 0.001) and long-term graft survival was significantly increased with a porto-caval shunt (hazard ratio 2.1, P < 0.001). This effect was even more pronounced for marginal organs. Usage of intraoperative porto-caval catheter-shunts is beneficial in cava sparing OLT and is associated with reduced ischemia-reperfusion injury and improved organ survival in particular for recipients of marginal organs.

Abstract
BACKGROUND Piggy-back method of transplantation, which involves preservation of the recipient retrohepatic inferior vena cava, has been suggested as an alternative to the conventional method of liver transplantation, where the recipient retrohepatic inferior vena cava is resected. OBJECTIVES To compare the benefits and harms of piggy-back technique versus conventional liver transplantation as well as of the different modifications of piggy-back technique during liver transplantation. SEARCH STRATEGY We searched The Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, and Science Citation Index Expanded until June 2010 for identifying randomised trials using search strategies. SELECTION CRITERIA Only randomised clinical trials, irrespective of language, blinding, or publication status were considered for the review. DATA COLLECTION AND ANALYSIS Two authors (KSG and VP) independently identified trials and independently extracted data. We calculated the mean difference (MD) or standardised mean difference (SMD) with 95% confidence intervals (CI) using both the fixed-effect and the random-effects models with RevMan 5 based on intention-to-treat analysis for continuous outcomes. For binary outcomes, we used the Fisher's exact test since none of the comparisons of binary outcomes included more than one trial. MAIN RESULTS Two trials randomised in total 106 patients to piggy-back method (n = 53) versus conventional method with veno-venous bypass (n = 53). Both trials were at high risk of bias. There was no significant difference in post-operative mortality, primary graft non-function, vascular complications, renal failure, transfusion requirements, intensive therapy unit (ITU) stay, or hospital stay between the two groups. The warm ischaemic time was significantly shorter in the piggy-back method than the conventional method (MD -11.50 minutes; 95% CI -19.35 to -3.65; P < 0.01). The proportion of patients who developed chest complications were significantly higher in the the piggy-back method than the conventional method (75.8% versus 44.1%; P = 0.01).One trial randomised 80 patients to piggy-back with porto-caval bypass (n = 40) versus piggy-back without porto-caval bypass (n = 40). This trial was at high risk of bias. There was no significant difference in post-operative mortality, re-transplantation due to primary graft non-function, vascular complications, renal failure, or hospital stay between the two groups. Fewer patients required blood transfusion in the piggy-back with porto-caval bypass group (55%) than the piggy-back without porto-caval bypass group (75%) (P = 0.02). There was no significant difference in the mean amount of blood transfused between the groups (MD -1.00 unit; 95% CI -2.19 to 0.19; P = 0.10). The ITU stay was significantly shorter in the piggy-back with porto-caval bypass group (2.9 days) than the piggy-back without porto-caval bypass group (4.9 days; MD -2.00 days; 95% CI -3.82 to -0.18; P = 0.03).There were no trials comparing piggy-back method with conventional method without veno-venous bypass or different techniques of piggy-back method. AUTHORS' CONCLUSIONS There is currently no evidence to recommend or refute the use of piggy-back method of liver transplantation.

Abstract
During orthotopic liver transplantation (OLT), a marked decrease in blood pressure following unclamping of the portal vein and liver reperfusion is frequently observed and is termed postreperfusion syndrome (PRS). The predictive factors and clinical consequences of PRS are not fully understood. The goal of this study was to identify predictors of PRS and morbidity/mortality associated with its occurrence during OLT in patients with cirrhosis. During a 3-year period, all consecutive OLT procedures performed in patients with cirrhosis were studied. Exclusion criteria were OLT for acute liver failure, early retransplantation, combined liver/kidney transplantation, and living-donor related transplantation. PRS was defined as a decrease in the mean arterial pressure of more than 30% of the value observed in the anhepatic stage, for more than 1 minute during the first 5 minutes after reperfusion of the graft. Transplantation was performed with preservation of the inferior vena cava with or without temporary portocaval shunt. Associations between PRS and donor and recipient demographic data, recipient operative and postoperative outcomes were tested with bivariate statistics. Independent predictors of PRS were determined in multivariable logistic regression analysis. Of the 75 patients included in the study, 20 patients (25%) developed PRS. In a multivariable analysis, absence of a portocaval shunt [odds ratio (95% confidence interval) = 4.42 (1.18-17.6)] and duration of cold ischemia [odds ratio (95% confidence interval) = 1.34 (1.07-1.72)] were independent predictors of PRS. Patients who experienced PRS displayed more postoperative renal failure and lower early (<15 days after OLT) survival (80% versus 96%; P = 0.04). In conclusion, the absence of portocaval shunt and the duration of cold ischemia were independent predictors of intraoperative PRS. PRS was associated with significant adverse postoperative outcome. These results provide realistic clinical targets to improve patient outcome after OLT for cirrhosis.

Abstract
Over the past 4 decades, the surgical techniques of liver transplantation (LTx) have permanently evolved and been modified. Among these, the modified piggyback (MPB) technique by Belghiti offers specific advantages. The objective of this study was to present our single-center experience with the MPB technique in 500 cases. Recipients' perioperative data were prospectively collected and evaluated. Postoperative and specific complications, stay in the intensive and intermediate care unit, and the mortality rate with cause of death were analyzed. Most recipients were classified as Child C (49.1%). For the patients who underwent LTx for the first time, alcoholic (23.9%) and viral (22.2%) cirrhosis and hepatocellular carcinoma (15.1%) were the prevalent indications. The overall median warm ischemia time, anastomosis duration, and operative time were 45, 108, and 320 minutes, respectively. The median intraoperative blood loss was 1500 mL. A venovenous bypass was never needed to maintain hemodynamic stability. Only in a few cases was temporary inferior vena cava clamping necessary. Most prominent surgical complications were hemorrhage, hematoma, and wound dehiscence. Renal failure occurred in 6.2% of patients. The overall median stay in the intensive and intermediate care unit was 14 days. The mortality rates within 30 and 90 days were 6.3% and 13.3%, respectively. No technique-related death occurred. The MPB technique by Belghiti is a feasible and simple LTx technique. The caval flow is preserved during the anhepatic phase, and this minimizes the need for venovenous bypass or portocaval shunt. This technique requires only 1 caval anastomosis, which is easy to perform with a short anhepatic phase. To minimize the risk of outflow obstruction, attention should be paid by doing a wide cavocavostomy cranially to the donor inferior vena cava in a door-lock manner. This technique can be applied in almost all patients undergoing LTx for the first time and liver retransplantation as well.

Abstract
Maintenance of portal and systemic venous return during the anhepatic phase of liver transplantation (LT) improves hemodynamic stability. With the piggyback technique, caval return is maintained; however, temporary clamping of the portal vein is still necessary. The use of a temporary portocaval shunt (TPCS) has been proposed to minimize the effect of portal venous interruption. The aim of this study was to perform a systematic review of the literature to determine whether there is evidence to support the routine use of a TPCS in LT. An electronic search of the literature from 1963 to 2007 was performed. A total of 4386 articles were identified, of which 8 met all the criteria and were included in the study. Because of the variability in reporting and the small number of studies, statistical comparison was not possible; however, a trend toward a shorter operative time, less blood product transfusion, and maintenance of higher mean arterial pressures during portal vein clamping was seen in patients with a TPCS. In conclusion, the available evidence, albeit scarce, supports the use of a TPCS in patients undergoing LT. A prospective randomized study of patients most likely to benefit from a TPCS is necessary to substantiate these findings.

Abstract
UNLABELLED We evaluated the consumption of blood products during liver transplantation in cirrhotic patients association with the placement of a temporary portacaval shunt (TPCS). PATIENTS AND METHODS We retrospectively divided 349 cirrhotic patients transplanted in our unit between March 1997 and October 2005 into two groups: transplants without a TPCS (group I, 189 cases) and those with a TPCS (group II, 160 cases). In all cases, we preserved the inferior vena cava (piggyback). The dependent variables were consumption of blood-derived products (banked red cells, recovered red cells, fresh frozen plasma, platelets), surgery time, kidney function, intensive care unit stay, and hospital stay. RESULTS Consumption of blood products was significantly lower among patients who received a TPCS. In group II, no platelet transfusion was required in 54% of the patients, and no banked red cells in 12% compared with 18% and 3%, respectively, among group I patients (P < .005). The mean overall transplant procedure time was 74 minutes shorter in group II (361 minutes) compared with group I (435 minutes) (P < .001). The overall hospital stay was shorter among patients transplanted after TPCS. CONCLUSION Liver transplantation with a TPCS was accompanied by a reduction in the intraoperative use of blood-derived products, especially platelet transfusion. Among other advantages, this reduction resulted in a shorter posttransplant hospital stay.
