RESUMO

Liver transplantation from elderly donors is expanding due to demand for liver grafts, aging of recipients and donors, and introduction of machine perfusion. We report on a liver transplant from a 100-year-old deceased donor after brain death. The liver was transplanted after the use of hypothermic machine perfusion to a 60-year-old recipient with advanced hepatocellular carcinoma undergoing neoadjuvant immunotherapy. Nine months after the transplant, the patient is alive with a functioning graft and no evidence of acute rejection or tumor recurrence.

RESUMO

BACKGROUND: The advantages of the robotic approach in minimally invasive liver surgery (MILS) are still debated. This study compares the short-term outcomes between laparoscopic (LLR) and robotic (RLR) liver resections in propensity score matched cohorts. METHODS: Data regarding minimally invasive liver resections in two liver surgery units were retrospectively reviewed. A propensity score matched analysis (1:1 ratio) identified two groups of patients with similar characteristics. Intra- and post-operative outcomes were then compared. The difficulty of MILS was based on the IWATE criteria. RESULTS: Two hundred sixty-nine patients underwent MILS between January 2014 and December 2021 (LLR = 192; RLR = 77). Propensity score matching identified 148 cases (LLR = 74; RLR = 74) consisting of compensated cirrhotic patients (100%) underwent non-anatomic resection of IWATE 1-2 class (90.5%) for a solitary tumor < 5 cm in diameter (93.2%). In such patients, RLRs had shorter operative time (227 vs. 250 min, p = 0.002), shorter Pringle's cumulative time (12 vs. 28 min, p < 0.0001), and less blood loss (137 vs. 209 cc, p = 0.006) vs. LLRs. Conversion rate was nihil (both groups). In RLRs compared to LLRs, R0 rate (93 vs. 96%, p > 0.71) and major morbidity (4.1 vs. 5.4%, p > 0.999) were similar, without post-operative mortality. Hospital stay was shorter in the robotic group (6.2 vs. 6.6, p = 0.0001). CONCLUSION: This study supports the non-inferiority of RLR over LLR. In compensated cirrhotic patients underwent resection of low-to-intermediate difficulty for a solitary nodule < 5 cm, RLR was faster, with less blood loss despite the shorter hilar clamping, and required shorter hospitalization compared to LLR.

RESUMO

Several risk factors for ischaemic-type biliary lesions (ITBL) after liver transplantation (LT) have been identified, but the role of portal vein perfusion at graft procurement is still unclear. This was a prospective study on double aortic and portal perfusion (DP) of liver grafts stratified by donor's decade (<60 yo; 60-69 yo; 70-79 yo and ≥80 yo) versus similar historical cohorts of primary, adult grafts procured with single aortic perfusion (SP) only. The primary study aim was to assess the role of DP on the incidence of ITBL. There was no difference in the incidence of overall biliary complications according to procurement technique for recipients of grafts <80 years. A higher incidence of ITBL was observed for patients receiving grafts ≥80 years and perfused through the aorta only (1.9 vs. 13.4%; P = 0.008). When analysing octogenarian grafts, donor male gender (HR = 6.4; P = 0.001), haemodynamic instability (HR = 4.9; P = 0.008), and type-2 diabetes mellitus (DM2) (HR = 3.0; P = 0.03) were all independent risk factors for ITBL, while double perfusion at procurement (HR = 0.1; P = 0.04) and longer donor intensive care unit (ICU) stay (HR = 0.7; P = 0.04) were protective factors. Dual aortic and portal perfusion has the potential to reduce post-transplant ITBL incidence for recipients of octogenarian donor grafts. Larger series are needed to confirm this preliminary experience.

RESUMO

This is a single center retrospective review of 19 consecutive liver transplant (LT) patients with hepatitis C virus (HCV)-related graft recurrent hepatitis who underwent transjugular intrahepatic portosystemic shunt (TIPS) at a median interval of 21 months (range: 5-50) from LT. Indications were refractory ascites in 11 patients (57.9%), hydrothorax in six (31.6%), and both in two (10.5%). TIPS was successful in 94.7% of cases (18/19) with only one procedure-related mortality (5.3%) owing to sepsis on day 35. At a median follow-up of 23 months (range: one month-nine yr), TIPS allowed for symptoms resolution in 16 patients (84.2%), with ascites resolving in all cases and hydrothorax persisting in 2. Post-TIPS patient survival at six months, one yr, and three yr was 84.2%, 73.7%, and 56.8%, respectively. We compared these results with a control group of 29 patients with HCV recurrence but without unresponsive ascites or hydrothorax. Patients in the control group had better survival than patients undergoing TIPS placement. However, survival of TIPS patients with a MELD score lower than or equal to 12 was similar to that of the control group. We conclude that TIPS may be used to treat complications secondary to HCV.

RESUMO

Maternal immunization is considered the best intervention in order to prevent influenza infection of pregnant women and influenza and pertussis infection of newborns. Despite the existing recommendations, vaccination coverage rates in Italy remain very low. Starting from August 2018, maternal immunization against influenza and diphtheria-tetanus-pertussis were strongly recommended by the Italian Ministry of Health. We conducted a cross sectional study to estimate the effectiveness of an educational intervention, conducted during childbirth classes in three general hospitals in the Palermo metropolitan area, Italy, on vaccination adherence during pregnancy. To this end, a questionnaire on knowledge, attitudes, and immunization practices was structured and self-administered to a sample of pregnant women attending childbirth classes. Then, an educational intervention on maternal immunization, followed by a counseling, was conducted by a Public Health medical doctor. After 30 days following the interventions, the adherence to the recommended vaccinations (influenza and pertussis) was evaluated. At the end of the study 326 women were enrolled and 201 responded to the follow-up survey. After the intervention, among the responding pregnant women 47.8% received influenza vaccination (+44.8%), 57.7% diphtheria-tetanus-pertussis vaccination (+50.7%) and 64.2% both the recommended vaccinations (+54.8%). A significant association was found between pregnant women that received at least one vaccination during pregnancy and higher educational level (graduation degree/master's degree), employment status (employed part/full-time) and influenza vaccination adherence during past seasons (at least one during last five years). The implementation of vaccination educational interventions, including counseling by healthcare professionals (HCPs), on maternal immunization during childbirth courses improved considerably the vaccination adherence during pregnancy.

RESUMO

The aim of the present work was to assess the incidence of neuro-nephrotoxicity after a single-staggered dose of calcineurin inhibitors (CI) with different immunosuppressive approaches. From January to December 2006, all liver transplantation (LT) recipients at risk of renal or neurological complications treated with extracorporeal photopheresis (ECP) + mycophenolate mofetil + steroids and staggered introduction of CI (ECP group) were compared with a historical control group on standard CI-based immunosuppression. The ECP group included 24 patients with a mean model for end-stage liver disease (MELD) score of 19.9 +/- 11.1. The control group consisted of 18 patients with a mean MELD score of 12.5 +/- 5.2 (p = 0.012). In the ECP group CI were introduced at a mean of 9.2 +/- 6.2 d (4-31 d) after LT. Five patients in the ECP group presented acute neuro-nephrotoxicity after the first CI administration on post-transplant d 4, 5, 6, 6, and 14. Overall patient survival at one, six, and 12 months was 100%, 95.8%, and 95.8% in the ECP group vs. 94.4%, 77.7%, and 72.2% in the control group (p < 0.001). In conclusion, we showed that CI toxicity may occur after a single-staggered dose administration, ECP seems to be a valuable tool for managing CI-related morbidity regardless of the concomitant immunosuppressive regimen, being associated with a lower mortality rate in the early post-transplant course.

RESUMO

BACKGROUND: ABO-incompatible (ABO-i) liver transplantation (LT) is a high-risk procedure due to the potential for antibody-mediated rejection (AMR) and cell-mediated rejection. The aim of the current report is to illustrate the results of a retrospective comparison study on the use of immunomodulation with therapeutic plasma exchange (TPE) associated to high-dose immunoglobulins (IVIg) and extracorporeal photopheresis (ECP) in ABO-i adult LT patients. PATIENTS AND METHODS: Between January 1996 and December 2005, 19 patients underwent ABO-i LT. The study was designed for a comparison between two groups of ABO-i LT. Group 1 (control group) consisted of 11 patients treated with TPE only. Group 2 (study group) included eight patients treated with TPE and IVIg. Moreover, all Group 2 patients received acute rejection prophylaxis with ECP. RESULTS: The graft survival at 6, 12, and 18 months was 63.6, 54.4, and 45.5% for Group 1 vs. 87.5, 87.5, and 87.5% for Group 2 (P < or = 0.001). In Group 1 there were 3(27.3%) cases of AMR; 5 (45.4%) biopsy-proven acute rejections (BPAR); 1 (9.1%) chronic rejection and 3 (27.3%) ischemic-type biliary lesions (ITBL). In Group 2 there were no cases of AMR, BPAR, chronic rejection, or ITBL (P = 0.013). CONCLUSION: At median follow-up of 568 days, TPE in combination with IVIg and ECP appears to protect the graft from AMR in ABO-i liver transplantation. Continued patient enrollment will allow validation of these preliminary observations or the opportunity to devise newer AMR-avoidance policies.

RESUMO

Patients with severe liver trauma may be referred to liver transplantation (LT), even though no universal algorithm is currently agreed upon. LT is usually performed as a two-stage procedure after failure of primary surgery or in the event of surgery-related acute liver failure (ALF), but pre-transplant patient management, appropriate selection criteria and prompt referral to LT centers are paramount for a favorable graft outcome. This is a report on a patient who underwent LT as a two-stage procedure for sepsis-related ALF after extended right hepatectomy for a complex abdominal blunt trauma. Prompt referral to the Liver Transplant Unit of the Cisanello Hospital, Pisa, where the whole spectrum of surgical options and intensive care support are available was crucial to allow successful LT in a timely fashion. Therefore, the authors strongly advocate the whole algorithm for patients with severe liver traumas be put under control of an experienced LT team in order to improve surgical results.

RESUMO

This article discusses a new simple, fast, and easily performed technique that allows reduction of morbidity and hospital stay after T-tube removal. A retrospective analysis was conducted of 145 recipients who underwent T-tube removal 3 months after orthotopic liver transplantation. Patients were divided in two groups: group 1 (n=93) underwent T-tube removal and contemporary placement under fluoroscopic guidance of a counter-drain. Group 2 (n=52) T-tubes were removed from the bile duct under fluoroscopy but were left in place as a counter-drain. Overall, there were 33 (22.7%) complications related to T-tube removal. Treatment was always conservative and no deaths were related to T-tube. In group 1, 29 (31.2%) complications occurred; and the mean hospital stay was 9.4+/-9.3 days. In group 2, four complications (7.7%) occurred (P=0.002); and the mean hospital stay was 5.8+/-5.5 days (P=0.012). The adoption of this new technique-under fluoroscopic guidance, using the T-tube itself as a counter-drain-for T-tube removal allowed us to significantly reduce biliary complications and hospital stay.

RESUMO

BACKGROUND: Graft shortage makes multiorgan procurement mandatory. We describe the results of a simplified method for the en bloc procurement of multiple organs, which permits isolated transplantation of all abdominal grafts, including the pancreas and the small bowel, to different recipients. METHODS: Three hundred forty-three multiorgan procurements were done with a simplified en bloc technique. RESULTS: None of the 1374 grafts that were procured sustained injuries that potentially precluded transplantation. Seventy-two grafts that were procured from 18 donors (5%) who were diagnosed with a neoplasm were discarded. Overall, 339 grafts that were procured from 325 donors were discarded because of specific contraindications, and 963 grafts (74%) were transplanted. Ninety-seven pancreata were transplanted. In 3 instances the pancreas and the small bowel were procured simultaneously and transplanted to different recipients. A total of 287 liver grafts were also transplanted at 13 different institutions. In 42 instances, the liver was not allocated to our center. Forty liver teams (95%) from 11 different institutions agreed to procure their grafts according to the simplified en bloc technique. Our team performed 18 procurements, and a surgeon from the liver transplantation team, who was assisted by one of the members of our team, performed 22 procurements. In all, 576 kidneys were transplanted, either alone or simultaneously, with other abdominal grafts at 15 different institutions. CONCLUSIONS: This procurement method has high yields, allows pancreas and small-bowel procurement, and can be learned readily.

RESUMO

Advanced donor age has been considered a risk factor for the use of organs for transplantation. We report the case of an orthotopic liver transplant performed using a 93-year-old donor. The donor had been admitted to the intensive care unit 3 days before due to cerebral hemorrhage. History, viral serology, liver function tests and hemodynamics were normal. At laparotomy, the liver appeared macroscopically normal; histology showed mild parenchymal congestion and focal signs of steatosis (less than 10%). The liver was therefore procured and transplanted into a 52-year-old recipient with alcoholic, post-hepatitis C. cirrhosis. Cold and warm ischemia times were 8 hours 20 min and 67 min, respectively. Production of bile was observed after reperfusion. Six months post-transplantation there is clinical and histological evidence of hepatitis C virus recurrence. Nevertheless, the patient enjoys an acceptable quality of life. Even very old donor livers can be used for transplantation, although it is still debatable whether hepatitis C virus-positive patients are good recipients of such livers.

RESUMO

BACKGROUND/AIMS: An effective recruitment plan and the use of donors with risk factors are essential means of compensating for the lack of organs, but mean a significant change in the type of donor. This study defines the characteristics of the donors currently used, evaluates their impact on short-term outcome and underlines the need for a different approach to organ selection. METHODOLOGY: Data concerning 244 patients were collected for the study of donor characteristics by age groups, and the multivariate analysis of the associated risk factors. RESULTS: There were no significant differences other than the cause of donor death and the appearance of the organ. The annual percentage of donors aged more than 60 years has increased from 5.2% to 47.6%; the percentage of organs from over-60-year-old donors discarded after bioptic sampling was 25.6% (10.4% for donors aged < 60 years). Perioperative mortality did not significantly differ on the basis of donor age (p = 0.186). CONCLUSIONS: Today's liver donors are mainly subjects who have died of cerebrovascular disease, often at an age of > 60 years, and are also affected by other diseases or metabolic alterations. They require a different method of evaluation and, in those aged more than 60 years, the routine use of histological examinations in organ selection. Furthermore, the judicious extension of the inclusion criteria and the characteristics of the currently available donors do not seem to affect short-term, post-transplant outcome.
