Impact of blood transfusion on early outcome of liver resection for colorectal hepatic metastases

The use of intra‐operative blood transfusion has been associated with worse surgical outcome in patients undergoing liver resection for malignancy.

Early regeneration of the remnant liver volume after right hepatectomy for living donation: A multiple regression analysis

Early liver regeneration was studied in a series of 70 patients who underwent right hepatectomy for living donation between November 2004 and January 2010. Liver regeneration was evaluated with multidetector computed tomography (MDCT) at a mean of 61.07 days after surgery. Presurgical variables [eg, age, weight, height, body mass index (BMI), liver function tests, creatinine levels, platelet counts, international normalized ratio, and glucose levels] and variables detected with preoperative MDCT imaging [eg, main portal vein diameter, steatosis, original liver volume, and spleen volume (SV)] were investigated as potential predictors of liver regeneration. The future remnant liver volume (FRLV) was preoperatively calculated with a virtual surgical cut. Liver function tests and creatinine levels were recorded on the 30th postoperative day. In addition, the onset of postoperative complications occurring within 90 days of surgery was analyzed, and the complications were codified according to the 5 tiers of the Clavien‐Dindo classification. In 26 of the 70 patients (37.14%), 100% or greater hepatic regeneration had occurred at 2 months. There was no association between the clinical outcome and the liver regeneration rate. A stepwise multiple regression analysis showed that a higher BMI (coefficient = 0.035, P < 0.0001) and preoperative parameters such as a smaller FRLV (coefficient = −0.002, P < 0.0001) and a greater SV/FRLV ratio (coefficient = 1.196, P < 0.0001) were predictors of greater liver regeneration.

Percutaneous transhepatic venous angioplasty in a two-yr-old patient with hepatic vein stenosis after partial liver transplantation.

Abstract:  We report one case of severe hepatic vein stenosis, in a two‐yr‐old pediatric patient with a left lateral split liver transplantation (S2–S3) and severe ascites, in whom color Doppler ultrasound failed to make the diagnosis and transhepatic balloon angioplasty was successfully performed.

How to face organ shortage in liver transplantation in an area with low rate of deceased donation

Despite advances in patient selection, surgical technique, immunosuppression, and peri-operative management, the need for liver replacement exceeds organ availability. Moreover, in Italy, where the overall rate of cadaver donation is 21 donors per million per year, there are areas of the country, such as Sicily, where the rate of cadaver donation is 9.3 donors per million per year. In fact, this ongoing shortage of organs has led surgeons to develop innovative techniques in an attempt to expand the donor pool, and clinicians are continually modifying criteria to accept organs, particularly the previously defined expanded or marginal donor organs, which are now defined as extended criteria donor. Rarely, in certain specific settings alternative strategies based on the appropriate donor–recipient match allowed the use of grafts that otherwise would have been discarded due to anatomic anomalies. The organ shortage becomes more problematic in the scenario of re-transplantation where the use of a limited resource such as a liver graft must be weighed against the risk of a more difficult surgery.

Recipient-donor age matching in liver transplantation: a single-center experience.

OBJECTIVE The aim of this study was to investigate whether donor age was a predictor of outcomes in liver transplantation, representing an independent risk factor as well as its impact related to recipient age-matching. METHODS We analyzed prospectively collected data from 221 adult liver transplantations performed from January 2006 to September 2009. RESULTS Compared with recipients who received grafts from donors <60 years old, transplantation from older donors was associated with significantly higher rates of graft rejection (9.5% vs 3.5%; P = .05) and worse graft survival (P = .021). When comparing recipient and graft survivals according to age matching, we observed significantly worse values for age-mismatched (P values .029 and .037, respectively) versus age-matched patients. After adjusting for covariates in a multivariate model, age mismatch was an independent risk factor for patient death (hazard ratio [HR] 2.13, 95% confidence interval [CI] 1.1-4.17; P = .027) and graft loss (HR 3.86, 95% CI 1.02-15.47; P = .046). CONCLUSIONS The results of this study suggest to that optimized donor allocation takes into account both donor and recipient ages maximize survival of liver-transplanted patients.

The pitfall of the cystic duct biliary anastomosis in right lobe living donor liver transplantation

Figure 1. (A) Intraoperative cholangiogram obtained by injection of dye through a catheter inserted directly into the incised common bile duct. The patent anastomosis between the recipient common hepatic duct and right lobe posterior segmental system is shown. The cystic duct anastomosis with the allograft anterior segmental biliary system is not visualized. The common bile duct just below the level of insertion of the cholangiogram catheter appears artificially narrowed due to the presence of a suture placed to prevent dye extravasation.

This image is superimposed on the cholangiogram of the patent right posterior system anastomosis with the recipient common hepatic duct obtained by direct catheter insertion into the common bile duct (see A).

Impact of recipients' socio-economic status on patient and graft survival after liver transplantation: The IsMeTT experience

AIM We aimed to determine whether education level and socioeconomic status in a cohort of liver transplant recipients in the south of Italy were potential predictors of graft and patient survival. METHODS This retrospective study included 221 liver transplant recipients at Istituto Mediterraneo per i Trapianti e Terapie ad Alta Specializzazione between January 2006 and September 2009. Donor gender and age, cold ischaemic time, extended criteria donors, recipient age, gender, body mass index, primary aetiology, Model for End-Stage Liver Disease score, co-morbidities, patient health score assessed on the basis of clinical follow-up, highest level of education achieved, and socioeconomic status were collected and analysed. RESULTS Kaplan-Meier analysis of survival measured by education level and socioeconomic status showed a higher survival rate in patients with higher education level (p=0.04) and socioeconomic status (p=0.01). After adjusting for all covariables, results of the multivariate Cox regression analyses showed that only socioeconomic status remained an independent and significant predictor of overall survival (Hazard Ratio=0.16, p=0.03). CONCLUSION Patient survival after liver transplantation was influenced by low income, low educational level, and lack of access to quality health care. Prospective clinical studies are necessary to fully identify the impact of socioeconomic status on long-term health outcomes, and to propose an evidence-based guide to clinical intervention.

The role of basiliximab induction therapy in adult-to-adult living-related transplantation and deceased donor liver transplantation: a comparative retrospective analysis of a single-center series.

AIM The aim of this study was to report our single-center experience with the use of basiliximab, in combination with a steroid and tacrolimus-based regimen in adult to adult living-related liver transplantation (ALRLT) and in deceased donor liver transplantation (DDLT). MATERIALS AND METHODS Seventy-seven consecutive ALRLT recipients (group 1) and 244 DDLT recipients (group 2) were analyzed. All patients received 2 20-mg doses of basiliximab (days 0 and 4 after transplantation) followed by tacrolimus (0.15 mg/kg/d; 10-15 ng/mL target trough levels) and a dose regimen of steroids. Follow-up ranged from 4-1972 days after transplantation in group 1 and from 1-2741 days in group. RESULTS In group 1, 89.32% of the patients remained rejection-free during follow-up, with an actuarial rejection-free probability of 93.51% within 3 months. Actuarial patient survival rate at 3 years was 84.49%. In group 2, 86.07% of the patients remained rejection-free during follow-up, with an actuarial rejection-free probability of 93.04% within 3 months. Actuarial patient survival rate at 3 years was 87.69%. We observed 14 cases of hepatitis C virus (HCV) recurrence in group 1 (prevalence of 26.92%) and 80 cases in group 2 (prevalence of 54.05%). CONCLUSION Basiliximab in association with tacrolimus and steroids is effective in reducing episodes of acute cellular rejection (ACR) and increasing ACR-free survival after ALRLT and DDLT. No difference in patient and graft survival was found between group 1 and 2, nor was there any difference in the incidence of ACR between the 2 groups. However, less risk of HCV recurrence was present in the LRLT group.

Evolution of surgical technique in conventional open hepatectomy for living liver donation over a 12-year period in a single center.

We report details of the experience from the largest Italian program with hepatic living donation, focusing particularly on the use of intraoperative ultrasound in liver transplantation and living donation. During a 12-year period we changed our surgical technique in the conventional open procedures thanks to the experience gained into the laparoscopic setting. Intraoperative ultrasound has been implemented during these delicate procedures for ensuring a fast and safer detection of the accessory veins and final severing of the vascular stumps during liver transection.

Complications in Immunosuppressive Therapy of Liver Transplant Recipients

BACKGROUND In liver transplantation (LT), modern immunosuppressive protocol is focused on early corticosteroid (CS) weaning. The aim of the study was to investigate all early transplant-related complications using Clavien grading system, in order to identify a significant relation in two homogenous groups of consecutive liver transplanted patients, only different for steroid avoidance in immunosuppressive regimen. MATERIALS AND METHODS One group was treated with a tacrolimus-based CS-free immunosuppressive protocol, the other one underwent tacrolimus plus low dose CS therapy. The preoperative continuous variables analyzed were age, gender, model for end-stage liver disease (MELD) score, and the pre-allocation score for predicting survival following liver transplantation (P-SOFT). RESULTS There were 39 patients in Group A (CS free) (37.9%), and 64 patients in Group B (CS on board) (62.1%). No statistically significant differences between the two groups were detected regarding the incidence and Clavien grade of complications (P = 0.116). No significant relation was revealed between Clavien rate of complications and tacrolimus-based CS-free immunosuppressive protocol, comparing the two subgroup of patient with P-SOFT score < 6 and ≥ 6 (P = 0.193). This association was noted comparing the two subgroups on tacrolimus plus low dose CS regimen (P = 0.013). CONCLUSION In this series, the use of CS in sick patient is associated with higher morbidity identified by the Clavien classification.
