    Abstract 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.

    Abstract Abdominal wall transplant is developed in the context of intestinal and multivisceral transplant, in which it is often impossible to perform a primary wall closure. Despite the fact that abdominal wall closure is not as consequential in liver transplant, there are circumstances in which it might determine the success of the liver graft, especially in situations that compromise the abdominal cavity and facilitate an abdominal compartment syndrome. CASE 1: A 14-year-old girl suffering from cryptogenic cirrhosis with severe portal hypertension that causes ascites and severe malnutrition. Uneventful liver transplant, with a graft procured from a 14-year-old donor. At the time of wall closure it was decided to implant a nonvascularized fascia graft to supplement the right side of the transverse incision, with a 17 x 7 cm defect. This required reintervention after 4 months for biliary stricture. At that point, the wall graft was almost completely integrated into the native tissue. CASE 2: A 63-year-old man, transplanted for hepatitis C virus+ hepatocellular carcinoma+ nonocclusive portal thrombosis. Thirty-six hours after transplant the patient developed portal thrombosis. Thrombectomy and closure with biological mesh were performed. After 24 hours he was reoperated on for abdominal compartment syndrome and temporary closure with a Bogotá bag. Six days later he underwent omentectomy, intestinal decompression, and left components separation, identifying a 25 x 20 cm defect. For definitive closure, a nonvascularized fascia graft procured from a different donor was used, accomplishing a reduction in intra-abdominal pressure. Nonvascularized fascia transplantation is an interesting alternative in liver transplant recipients with abdominal wall closure difficulties.

    Title translation Arachnoid cysts: Embriology and pathology.
    Abstract There is still great controversy surrounding the origin of the arachnoid cyst. The most accepted theory in the case of congenital cysts explains how they are formed from an anomalous development of the arachnoid membrane, which is unfolded allowing the accumulation of cerebrospinal fluid inside and creating a cyst. This theory seems to explain the origin of convexity and sylvian cistern arachnoid cysts, whereas those in other locations might be due to other mechanisms. In the anatomopathological analysis, the arachnoid cyst wall can be seen as having few differences from normal, although thickened due to an increase quantity of collagenous material. A description of the embryological development of the arachnoid layer and cyst formation is presented, describing the main anatomopathological findings.

    Abstract 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.

    Abstract 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.

    Abstract Background: The McCluskey index has been used as a tool to predict massive bleeding (>6 red blood cells units) during orthotropic liver transplantation. The objective of this study is to verify its efficacy at our institution.
    Materials and methods: Between May 1998 and December 2017, we performed 1216 orthotropic liver transplantations, of which 1016 had sufficient data registered with respect to hemoderivative transfusion. We divided these patients into groups based on the original study of McCluskey. This study was approved by the ethical committee of our Institution and was performed in accordance with the Declaration of Helsinki.
    Results: The mean Model for End-Stage Liver Disease score in the 4 groups was 7.5 (range, 7-8) for low risk; 13 (range, 3-32) for medium risk, 17 (range, 8-41) for high risk, and 25 (range, 11-36) for very high risk (P < .001). No significant differences were observed regarding body mass index or hospital stay. No differences have been found in the number of suboptimal donors among the groups. With respect to hemoderivative transfusions, we observed the following for red blood cells: 7 (range, 6-8) units for low risk; 5.5 (range, 0-74) for medium risk; 7 (range, 0-73) for high risk, and 12 (range, 5-30) for very high risk (P < .001) and transfusion of plasma: 12 (range, 10-15) units for low risk; 11 (range, 0-89) for medium risk; 14 (range, 0-76) for high risk, and 13 (range, 3-30) for very high risk (P = .001).
    Conclusions: The McCluskey index is a good indicator of the risk of hemorrhage and hence the necessity of transfusion.

    Abstract Introduction: Intraoperative bleeding during liver transplantation has been correlated with a higher risk of morbidity and mortality and decrease in patient and graft survival.
    Materials and methods: Between January 2006 and December 2016 we performed 783 orthotopic liver transplants. After applying exclusion criteria, we found liver grafts from donors after circulatory death (DCD, group A) were used in 69 patients and liver grafts from donors after brain death (group B) were used in 265 patients.
    Results: No difference was found in terms of sex, body mass index, Model for End-Stage Liver Disease score, indication for transplantation, intensive care unit stay, and Child-Pugh score. The mean transfusion of hemoderivates was as follows: red blood cell 9 (0-28) units in group A vs 6 (0-20) units in group B (P = .004) and fresh frozen plasma 10 (0-29) units in group A vs 9.5 (0-23) in group B (P = .000). The only 2 factors related to massive blood transfusion (>6 units of red blood cell) were uncontrolled DCD condition (odds ratio = 2.38; 95% confidence interval, 1.32-4.31; P = .004), and higher Model for End-Stage Liver Disease score (odds ratio = 2.63; 95% confidence interval, 1.53-4.55; P = .001). Survival at 1, 3, and 5 years was 81.3%, 70.2%, and 68.9% in group A vs 89%, 83.7%, and 78% in group B (P = .070).
    Conclusion: The use of liver grafts from DCDs is associated with increased necessity of transfusion of hemoderivates in comparison with the use of liver grafts from donors after brain death.

    Abstract 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.
