ABSTRACT
Pyogenic liver abscess (PLA) is a life-threatening infection in both liver transplant (LT) and non-LT patients. Several risk factors, such as benign and malignant hepatopancreatobiliary diseases and colorectal tumors have been associated with PLA in the non-LT population, and hepatic artery stricture/thrombosis, biliary stricture, and hepaticojejunostomy in the LT patients. The objective of this study is to compare the outcomes of patients with PLA in LT and non-LT patients and to determine the risk factors associated with patient survival. From January 2000 to November 2020, a total of 296 adult patients were diagnosed of PLA in our institution, of whom 26 patients had previously undergone liver transplantation (LTA group), whereas 263 patients corresponded to the non-LTA population. Seven patients with PLA who had undergone previous kidney transplantation were excluded from this retrospective study. Twenty-six patients out of 1503 LT developed PLA (incidence of 1.7%). Median age was significantly higher in non-LTA patients (p = .001). No significant differences were observed in therapy. PLA recurrence was significantly higher in LTA than in non-LTA (34.6% vs. 14.8%; p = .008). In-hospital mortality was greater in the LT group than in the non-LT group (19.2% vs. 9.1% p = .10) and was identified in multivariable analysis as a risk factor for mortality (p = .027). Mortality rate during follow-up did not show significant differences between the groups: 34.6% in LTA patients versus 26.2% in non-LTA patients (p = .10). The most common causes of mortality during follow-up were malignancies, Covid-19 infection, and neurologic disease. 1-, 3-, and 5-year actuarial patient survival rates were 87.0%, 64.1%, and 50.4%, respectively, in patients of LTA group, and 84.5%, 66.5%, and 51.0%, respectively, in patients with liver abscesses in non-LTA population (p = .53). In conclusion, LT was a risk factor for in hospital mortality, but not during long-term follow-up.

BACKGROUND: Percutaneous drainage (PD) and antibiotics are the therapy of choice (non-surgical therapy [non-ST]) for pyogenic liver abscesses (PLA), reserving surgical therapy (ST) for PD failure. The aim of this retrospective study was to identify risk factors that indicate the need for ST. METHODS: We reviewed the medical charts of all of our institution's adult patients with a diagnosis of PLA between January 2000 and November 2020. A series of 296 patients with PLA was divided into two groups according to the therapy used: ST (n = 41 patients) and non-ST (n = 255). A comparison between groups was performed. RESULTS: The overall median age was 68 years. Demographics, clinical history, underlying pathology, and laboratory variables were similar in both groups, except for the duration of PLA symptoms < 10 days and leukocyte count which were significantly higher in the ST group. The in-hospital mortality rate in the ST group was 12.2% vs. 10.2% in the non-ST group (p = 0.783), with biliary sepsis and tumor-related abscesses as the most frequent causes of death. Hospital stay and PLA recurrence were statistically insignificant between groups. One-year actuarial patient survival was 80.2% in the ST group vs. 84.6% in the non-ST (p = 0.625) group. The presence of underlying biliary disease, intra-abdominal tumor, and duration of symptoms for less than 10 days on presentation comprised the risk factors that indicated the need to perform ST. CONCLUSIONS: There is little evidence regarding the decision to perform ST, but according to this study, the presence of underlying biliary disease or an intra-abdominal tumor and the duration of PLA symptoms < 10 days upon presentation are risk factors that should sway the surgeons to perform ST instead of PD.

Difficulty in obtaining adequate abdominal wall closure due to loss of the abdominal domain is a frequent complication of multivisceral, isolated intestinal transplantation and in some cases of liver transplantation. Various methods for primary closure have been proposed, including the use of synthetic and biological meshes, as well as full-thickness abdominal wall and non-vascularized rectus fascia grafts. We describe a novel technique for abdominal wall procurement in which the graft is perfused synchronously with the abdominal organs and can be transplanted as a full-thickness wall or as a non-vascularized rectus fascia graft. We performed six transplants of non-vascularized rectus fascia in three intestinal transplants, one multivisceral transplant, and two liver transplants. The size of the covered abdominal wall defects ranged from 17 cm × 7 cm to 25 cm × 20 cm. Only one patient developed graft infection secondary to enterocutaneous fistula requiring surgical correction and removal of the fascia graft. This patient, as well as two other patients, died due to sepsis. Our procurement technique allows removal of the rectus fascia graft to cover the abdominal wall defect, providing a feasible solution for treatment of abdominal wall defects in recipients after abdominal organ transplantation.

Whether immunosuppression impairs severe acute respiratory syndrome coronavirus 2-specific T cell-mediated immunity (SARS-CoV-2-CMI) after liver transplantation (LT) remains unknown. We included 31 LT recipients in whom SARS-CoV-2-CMI was assessed by intracellular cytokine staining (ICS) and interferon (IFN)-γ FluoroSpot assay after a median of 103 days from COVID-19 diagnosis. Serum SARS-CoV-2 IgG antibodies were measured by ELISA. A control group of nontransplant immunocompetent patients were matched (1:1 ratio) by age and time from diagnosis. Post-transplant SARS-CoV-2-CMI was detected by ICS in 90.3% (28/31) of recipients, with higher proportions for IFN-γ-producing CD4+ than CD8+ responses (93.5% versus 83.9%). Positive spike-specific and nucleoprotein-specific responses were found by FluoroSpot in 86.7% (26/30) of recipients each, whereas membrane protein-specific response was present in 83.3% (25/30). An inverse correlation was observed between the number of spike-specific IFN-γ-producing SFUs and time from diagnosis (Spearman's rho: -0.418; p value = .024). Two recipients (6.5%) failed to mount either T cell-mediated or IgG responses. There were no significant differences between LT recipients and nontransplant patients in the magnitude of responses by FluoroSpot to any of the antigens. Most LT recipients mount detectable-but declining over time-SARS-CoV-2-CMI after a median of 3 months from COVID-19, with no meaningful differences with immunocompetent patients.

BACKGROUND: Graft primary non-function (PNF) is the most severe complication after orthotopic liver transplantation (OLT) and is frequently associated with livers from uncontrolled circulatory death (uDCD). METHODS: We reviewed retrospectively the incidence, risk factors, and outcome of patients showing PNF after receiving uDCD liver grafts. The series comprises 75 OLT performed during 11 years. RESULTS: The incidence of PNF using uDCD livers was 8%. We compared patients who developed PNF (n = 6) vs. patients without PNF (n = 69). Mean pump flow of donors during normothermic regional perfusion (NRP) was significantly lower in PNF (p = .032). Day 1 post-OLT levels of transaminases and the incidence of renal complications and postoperative mortality were also significantly higher in the PNF group, but 5-year patient survival was similar in both groups (66.7% in PNF and 68.5% in non-PNF). All PNF patients underwent re-OLT, and 2 died. PNF incidence has decreased in the last 5-years. Binary logistic regression analysis confirmed final ALT value >4 times the normal value as risk factor for PNF, and median donor pump flow >3700 ml/min as protective effect. CONCLUSIONS: Adequate donor pump flow during NRP was a protective.

The utilization of livers from donation after uncontrolled circulatory death (uDCD) increases the availability of liver grafts, but it is associated with a higher incidence of biliary complications (BCs) and lower graft survival than those organs donated after brain death. From January 2006 to December 2016, we performed 75 orthotopic liver transplantations (OLTs) using uDCD livers. To investigate the relationship of BCs with the use of uDCD OLT, we compared patients who developed BCs (23 patients) with those who did not (non-BC group, 43 patients) after excluding cases of hepatic artery thrombosis (a known cause of BC) and primary nonfunction. The groups had similar uDCD donor maintenance, donor and recipient characteristics, and perioperative morbidity/mortality rates, but we observed a higher rate of hepatocellular carcinoma and hepatitis C virus in the non-BC group. Percutaneous transhepatic biliary dilation, endoscopic retrograde cholangiopancreatography dilation, Roux-en-Y hepaticojejunostomy (HJ), a T-tube, and retransplantation were used for BC management. In the BC group, 1-, 3-, and 5-year patient survival rates were 91.3%, 69.6%, and 65.2%, respectively, versus 77.8%, 72.9%, and 72.9%, respectively, in the non-BC group (P = 0.89). However, 1-, 3-, and 5-year graft survival rates were 78.3%, 60.9%, and 56.5%, respectively, in the BC group versus 77.8%, 72.9%, and 72.9%, respectively, in the non-BC group (P = 0.38). Multivariate analysis did not indicate independent risk factors for BC development. In conclusion, patient and graft survival rates were generally lower in patients who developed BCs but not significantly so. These complications were managed in the majority of patients through radiological dilation, endoscopic dilation, or Roux-en-Y HJ. Retransplantation is necessary in rare cases after the failure of biliary dilation or surgical procedures.

BACKGROUND: Which are the consequences of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in liver transplant (LT) recipients? METHODS: We attempted to address this question by reviewing our single-center experience during the first 2 months of the pandemics at a high incidence area. RESULTS: Nineteen adult patients (5 females) were diagnosed by May 5, 2020. Median age was 58 (range 55-72), and median follow-up since transplantation was 83 (range 20-183) months. Cough (84.2%), fever (57.9%), and dyspnea (47.4%) were the most common symptoms. Thirteen patients (68.4%) had pneumonia in x-ray/CT scan. Hydroxychloroquine was administered in 11 patients, associated with lopinavir/ritonavir and interferon ß in 2 cases each. Immunomodulatory therapy with tocilizumab was used in 2 patients. Immunosuppression (IS) was halted in one patient and modified in only other two due to potential drug interactions. Five (26.3%) patients were managed as outpatient. Two patients (10.5%) died, 10 (52.6%) were discharged home, and 2 (10.5%) were still hospitalized after a median follow-up of 41 days from the onset of symptoms. Baseline IS regimen remained unchanged in all surviving recipients, with good liver function. CONCLUSIONS: Our preliminary experience shows a broad spectrum of disease severity in LT patients with COVID-19, with a favorable outcome in most of them without needing to modify baseline IS.

BACKGROUND: Controversy remains with regard to the higher risk of intra-abdominal infections and lower patient and graft survival when peritoneal dialysis (PD) rather than hemodialysis (HD) is used in simultaneous pancreas-kidney transplantation (SPKT). METHODS: From March 1995 to December 2015, we performed 165 SPKTs. Prior to transplant, patients received hemodialysis (group HD; n = 98) or peritoneal dialysis (group PD; n = 67). A comparison was made to analyze post-transplant complications and patient, pancreas, and kidney graft survivals. RESULTS: Donor, pretransplant, and perioperative recipient variables were similar in both groups. Overall rates of infections (69.4% in HD vs 73.1% in PD; P = .50) and intra-abdominal infections (31.6% in HD vs 35.8 in PD; P = .57) were similar in both groups. The rates of pancreatitis, hemorrhage or thrombosis of the graft, duodenal graft leak, relaparotomy, transplantectomy, pancreas rejection, and retransplantation were similar in both groups. Patient survival at 1, 3, and 5 years (95.9%, 93.9%, and 93.9% in HD vs 95.5%, 92.2%, and 90.4% in PD; P = .54) and pancreas graft survival (83.6%, 78.0%, and 71.8% in HD vs 79.2%, 77.4%, and 71.0% in PD; P = .8) were similar in both groups. Kidney graft survival was similar in both groups. Pancreas graft thrombosis, rejection, and relaparotomy for intra-abdominal complications were independent predictors of lower pancreas graft survival, but dialysis modality did not influence patient or graft survival. CONCLUSIONS: Pre-SPKT modality of dialysis does not significantly influence overall or intra-abdominal infection and patient, pancreas, or kidney graft survivals.

BACKGROUND: Liver abscess after orthotopic liver transplantation (OLT) is a rare, life-threatening complication. The aim of this study is to analyze the incidence, risk factors, clinical manifestations, treatment and outcomes of liver abscesses after OLT. METHODS: We perform a retrospective review of the patients who developed one or more liver abscesses among a series of 984 patients who underwent OLT between January 2000 and December 2016. RESULTS: Fourteen patients (1.5%) developed 18 episodes of liver abscesses, and the median time from OLT to the diagnosis of liver abscess was 39.7 months. Major predisposing factors were biliary strictures in 11 patients, hepatic artery thrombosis in 8, re-OLT in 3, choledochojejunostomy in 2, living donor OLT in 2, donor after cardiac death in 1, split liver in 1, and liver biopsy in 1. All patients were managed by intravenous antibiotics; percutaneous drainage was performed in 10 patients, while 2 patients underwent re-OLT. The mortality rate related to liver abscesses was 21.4%. The mean hospital stay was 30 ± 19 days, and during a mean follow-up of 93 ± 78 months, three other patients died. CONCLUSIONS: Liver abscesses must be managed with antibiotic therapy and percutaneous drainage, but when these conservative measures fail (persistent abscess and sepsis), a re-OLT must be performed in order to prevent the high mortality associated with this severe complication.

INTRODUCTION: gallbladder cancer is the most common biliary neoplasm and the sixth most common tumor of the digestive system. The disease has an ominous prognosis, with a 5-year survival rate of approximately 5%. It is usually diagnosed late and surgical resection is the only potential cure. METHODS: a retrospective study was carried out in 92 patients with a pathological diagnosis of gallbladder cancer from January 2000 to January 2016. RESULTS: the mean age of cases was 72 ± 11 years; 64 subjects were females and 28 were males. Symptoms at admission included abdominal pain (78%), anorexia (77%), nausea (76%) and jaundice (45%). Surgery was indicated in 92 (100%) patients and 59 (64%) underwent a curative/intent resection. The initial surgical procedures included simple cholecystectomy in 69 (75%) cases and extended cholecystectomy in eleven (11%) subjects. Rescue surgery was performed in 15 patients with tumor tissue in the cholecystectomy specimen; ten individuals underwent an R0 curative resection. Adjuvant therapy was administered in 30 (33%) patients. The median survival in our series was 12.5 months, with survival rates of 57%, 30% and 20% at one, three and five years, respectively. CONCLUSION: to conclude, surgical treatment with a complete tumor resection should be considered for all patients, provided that their clinical status allows it.

INTRODUCTION: Renal carcinoma represents 3% of all solid tumors and is associated with renal or inferior caval vein (IVC) thrombosis between 2-10% of patients, extending to right atrial in 1% of cases. METHODS: This is a retrospective study that comprises 5 patients who underwent nephrectomy and thrombectomy by laparotomy because of renal tumor with IVC thrombosis level iii. RESULTS: Four patients were males and one was female, and the mean age was 57,2 years (range: 32-72). Most important clinical findings were hematuria, weight loss, weakness, anorexia, and pulmonary embolism. Diagnostic confirmation was performed by CT scanner. Metastatic disease was diagnosed before surgery in 3 patients. Suprahepatic caval vein and hepatic hilium (Pringle's maneouver) were clamped in 4 patients, and ligation of infrarrenal caval vein was carry out in one patient. Five patients developed mild complications (Clavien I/II). No patient died and the mean hospital stay was 8,6 days. All patients were treated with chemotherapy, and 3 died because distant metastasis, but 2 are alive, without recurrence, at 5 and 60 months, respectively. CONCLUSIONS: Nephrectomy and thrombectomy in renal tumors with caval thrombosis can be curative in absence of metastasis or, at less, can increase survival or quality of live. Then these patients must be treated in liver transplant units because major surgical and anesthesiologic expertise. Adjuvant treatment with tyrosin kinase inhibitors must be validate in the future with wider experiences.

BACKGROUND: Diverticular disease of the appendix is an uncommon condition, with an incidence from 0.004 to 2.1%. It usually occurs between the fourth or fifth decades of life, does not present gastrointestinal symptoms but only insidious abdominal pain. Patients usually delay consultation, leading to increased morbidity and mortality. The aim of this study was to determine the clinical features of diverticular disease of the appendix. METHODS: A retrospective study of all patients undergoing appendectomy in a tertiary hospital between September 2003 and September 2013 was performed. RESULTS: During this period, 7,044 appendectomies were performed, and 42 cases of diverticular disease of the appendix were found, which represents an incidence of 0.59%. A total of 27 patients were male. The mean age was 46.6±21 years. The average hospital stay was 4.5 days. A perforated appendix was identified in 46% of patients. In 80% of the cases, a complementary imaging test was performed. The incidence of neoplastic disease with diverticulum of the appendix was 7.1%. CONCLUSIONS: Diverticular disease of the appendix is an incidental finding. In its acute phase, it presents as an acute appendicitis. The treatment of choice is appendectomy. It presents a higher risk of developing neoplastic disease of the appendix.

Background: Liver transplantation is an increasingly frequent surgical procedure, with elevated rates of postoperative incisional hernias ranging from 5% to 46%. There are numerous known risk factors for incisional hernia, including the type of incision, patient sex, and presence of comorbidities such as diabetes, ascites, older age, and the use of steroids. Most studies on the treatment of incisional hernias in patients who have undergone liver transplantation have shown consistently high rates of complications. Consequently, we propose the use of nonvascular fascia for the symptomatic treatment of incisional hernias in patients with concomitant liver transplantation. Methods: We performed our new technique on 8 patients, who had previously undergone liver transplantation, between January 2019 and January 2023. The patients were examined using imaging techniques during the follow-up period. Results: Of the 8 patients, 7 were liver transplant recipients and 1 was a combined liver-kidney transplant patient. The median donor age was 57 y (5-66 y), whereas the mean recipient age was 58 y (31-66 y). The median patient height and weight were 163 cm (117-185 cm) and 76 kg (17-104 kg), respectively. Immunosuppression did not change in fascia recipients. The median time between transplantation and hernia repair surgery was 41 mo (5-116 mo). The sizes of the aponeurotic defects varied from 6â ×â 6 to 25â ×â 20 cm. Two patients experienced complications: one experienced bulging that required reintervention and the other experienced surgical site seroma. There was no mortality related to the use of the technique, and none were reported during follow-up. Conclusions: With its promising results, nonvascularized fascial transplantation can be a successful treatment for incisional hernias in patients who had previously received a liver transplant.
ABSTRACT
BACKGROUND: Massive blood transfusion (MBT) is a common occurrence in liver transplant (LT) patients. Recipient-related risk factors include cirrhosis, history of multiple surgeries and suboptimal donors. Despite advances in surgical techniques, anesthetic management and graft preservation have decreased the need for transfusions, this complication has not been completely eliminated. METHODS: One thousand four hundred and sixty-nine LT were performed at our institution between May 2003 and December 2020, and data was available regarding transfusion for 1198 of them. We divided the patients into two groups, with regards to transfusion of 6 or more units of packed red blood cells in the first 24 h posttransplant, and we analyzed the differences between the groups. RESULTS: Out of the 1198 patients, 607 (50.7%) met criteria for MBT. Survival was statistically lower at 1, 3, and 5 years when comparing the groups that had MBT to those that did not (92.6%, 85.2% and 79.7%, respectively, in the non MBT group, vs. 78.1%, 71.6% y 66.8%, respectively, in the MBT group). MBT was associated with a 1.5 mortality risk as opposed to non-MBT patients. Logistical regression analysis of our variables yielded the following results for a new model, including serum creatinine (OR 1.97), sodium (OR 1.73), hemoglobin (OR 1.99), platelets (OR 1.37), INR (OR 1.4), uDCD (OR 2.13) and split liver donation. CONCLUSION: Massive blood transfusion impacts patient survival in a statistically significant way. The most significant risk factors are preoperative hemoglobin, INR and serum creatinine.

BACKGROUND: Twenty percent of intestinal transplant recipients will require a surgical alternative to conventional primary abdominal wall closure. Abdominal wall transplant is a developing technique that is increasingly performed for this purpose in isolated intestinal or multivisceral recipients; however, adequate closure of the donor is paramount while simultaneously obtaining a large enough graft. The aim of this study is to describe alternative surgical techniques for closure of the donor in cases in which abdominal wall graft extraction hinders subsequent donor abdominal closure. METHODS: We describe the cases of 2 young donors in whom intestinal extraction was not carried out and in whom wall closure was not feasible, following standard techniques after abdominal wall graft extraction. We performed 2 different procedures to obtain adequate closure. 1. Hemifascia and hemiabdominal wall graft extraction: It is an option when the recipients require an extension of the abdominal aponeurosis yet have enough skin to guarantee skin closure. The perfusion of both epigastric arteries is needed. The remaining cutaneous half is used for closing the donor's abdomen.2. Hemiabdominal wall graft extraction: Full-thickness abdominal wall is harvested from the donor, selecting the most vascularized half. It is an alternative for recipients who need a skin implant in addition to an aponeurosis extension. This option should be used for recipients who do not require a large fascial graft but do require a significant cutaneous graft. The nontransplanted half of full-thickness abdominal wall is used for donor closure. RESULTS: Abdominal wall transplant allows for expansion of the abdominal cavity in organ recipients and reduces the risk of compartmental syndrome and subsequent ischemia. However, the donor wall defect must be considered. The choice of donation technique was based on the magnitude of the defect in the donor as well as the size of defect to be covered in the recipient while ensuring a tight and complete closure of the donor's abdomen. CONCLUSIONS: Abdominal wall graft extraction can be performed using nonconventional techniques that account for the extension and type of coverage needed by the recipient while guaranteeing proper closure of the donor.

BACKGROUND: An increased number of older recipients underwent liver transplantation in recent years, and consequently needing to obtain more liver grafts. In order to increase this pool, in 2006, we initiated the use of livers from uncontrolled circulatory death (uDCD). We analyzed the use of uDCD livers in sexagenarian recipients and their effect on overall survival. METHODS: A retrospective and comparative study was performed among 4 groups according to recipient age (less or greater than 60 years) and donor type (donor brain death [DBD] or uDCD): Group A: DBD livers in recipients aged <60 years (n = 169); Group B: uDCD livers in recipients aged <60 years (n = 36); Group C: DBD livers in recipients aged >60 years (n = 96); and Group D: uDCD livers in recipients aged >60 years(n = 39). RESULTS: Intraoperative transfusion, biliary complications, primary non-function, acute rejection, chronic renal dysfunction, retransplantation, and mortality during follow-up (cardiovascular diseases in 3 patients, hepatitis C virus recurrence in 4 patients, and de novo malignancies in 3 patients) were significantly higher, and 5-year patient and graft survival was significantly lower in sexagenarian recipients. Bilirubin and packed red blood cells transfusion were risk factors for patient survival, whereas hepatocelular carcinoma, creatinine, and packed red blood cells transfusion were risk factors for patient survival. Recipient age (<60 years) was confirmed as protective factor for patient and graft survival, whereas the use of uDCD was not a risk factor for patient or graft survival. CONCLUSIONS: Use of a uDCD liver did not demonstrate as a risk factor for patient and graft survival, and recipient age (<60 years) was a protective factor for patient and graft survival.

Controversy exists regarding whether the rate of hepatocellular carcinoma (HCC) recurrence after orthotopic liver transplantation (OLT) differs when using livers from donation after controlled circulatory death (DCD) versus livers from donation after brain death (DBD). The aim of this cohort study was to analyze rates of HCC recurrence, patient survival, and graft survival after OLT for HCC, comparing recipients of DBD livers (n = 103) with recipients of uncontrolled DCD livers (uDCD; n = 41). No significant differences in tumor size, tumor number, serum alpha-fetoprotein, proportion of patients within Milan criteria, or pre-OLT bridging therapies were identified between groups, although the waitlist period was significantly shorter in the uDCD group (p = 0.040). HCC recurrence was similar between groups. Patient survival was similar between groups, but graft survival was lower in the uDCD group. Multivariate analysis identified recipient age (p = 0.031), pre-OLT bridging therapy (p = 0.024), and HCC recurrence (p = 0.048) as independent risk factors for patient survival and pre-OLT transarterial chemoembolization (p = 0.045) as the single risk factor for HCC recurrence. In conclusion, similar patient survival and lower graft survival were observed in the uDCD group. However, the use of uDCD livers appears to be justified due to a shorter waitlist time, and lower waitlist dropout and HCC recurrence rates.
