Abstract Introduction The liver retransplantation rate in Spain is about 6%. The main causes are primary nonfunction, vascular complications, chronic rejection, and recurrent liver disease. The ...results of this procedure are worse than those of first transplantations. Patients and Methods This retrospective study evaluated our experience with 54 retransplantations performed between January 1992 and December 2006, which were 5.6% of the 960 orthotopic liver transplantations (OLT) during this period. Results In this study, 34.7% of the retransplantations were performed between 4 and 30 days after the first transplantation; another 34.7% were within 1 year. Also, 48.9% of the retransplantations were performed in urgent situations. The main causes for retransplantation during the first month were primary hepatic failure (n = 14) and vascular complications (n = 4). After the first month the main causes were chronic rejection (n = 9), recurrence of hepatic disease (n = 3), and biliary complications (n = 4). Postoperative mortality was 23.9% and morbidity was 76.3%. However, 21.2% of the patients needed a third transplant. The overall rate of patient survival was 60.4% (n = 32) and of graft survival was 56.6% (n = 30). The 5-year actuarial graft survival rate was 65.4% with a mean survival time of 89.84 ± 8.72 months; the 5-year patient survival rate was 64% with a mean survival time of 114.7 ± 12.53 months. Worse survival was observed in chronic rejection and in retransplantations performed between 31 and 360 days. Conclusions Liver retransplantation presents greater surgical complexity than the first transplantation, but is a good option for patients with failure of the first graft with a 5-year patient and graft survival rate greater than 65%.
Abstract Background Neurocysticercosis (NCC) is a disorder caused by the Taenia solium larva. It is the most common parasitosis of the central nervous system (CNS). Its distribution is universal, but ...it is endemic in many developing countries and in the third world. In Spain most patients come from countries where the condition is endemic. However, sporadic cases occur among the population of rural regions. NCC in transplant recipients is uncommon. One renal transplant recipient developed NCC but responded to treatment with praziquantel. Recently, it has been reported to complicate a liver transplantation. Case report The patient was a 49-year-old Ecuatorian man who received a cadaveric donor liver graft in June 2001 due to acute liver failure induced by toadstool and was under treatment with FK506. In January 2006, the patient presented with a generalized onset of a tonic-clonic seizure for 1 minute without sphincter incontinence, headache, fever, or previous brain trauma. Neurological evaluation did not show evidence of organic brain dysfunction. The neuroimaging findings (brain) computed tomography scan, magnetic resonance imaging were compatible with NCC: many cystic lesions intra- and extraparenchymatous with a scolex visible in three of them. Serology for cysticercosis in plasma was initially indeterminate but positive afterward. The patient was treated with anticonvulsivants (valproic acid) and albendazole. Systemic steroids were added in order to reduce the edema produced upon death of the cyst. Treatment lasted 3 weeks and it was completed without complications or neurological symptoms. Liver function was not affected. One year later the patient remained asymptomatic. Conclusion NCC is a condition that must be included in the differential diagnosis of patients with CNS involvement and cystic lesions on neuroimaging investigations in transplant recipients, especially patients originating from or traveling to endemic areas. First-line therapy for active cysts includes antiparasitic drugs (albendazole or praziquantel) as well as steroids and anticonvulsivants. In our patient, this therapy was effective.
Abstract Acute liver failure is an uncommon disease but its overall mortality rate is still high without liver transplantation, which is the treatment of choice for patients achieving certain ...criteria. We have reported herein the experience and retrospectively analyzed results of liver transplantation for acute liver failure since the beginning of activity of our group, which is the only one in the region of “Castilla y Leon” (Spain). In 10 years, 14 patients underwent emergency transplantation among an overall series of 325 subjects. The patients were generally young men and women; the average wait list time was 2.14 days. The most common etiology was toxic exposure (no cases were related to acetaminophen overdose), followed by viral infection (all because of acute hepatitis B). Our posttransplant outcomes were: perioperative mortality, 0%; posttransplant in-hospital mortality, 14%; and 1-y, 3-y, and 5-year survival rates of 77.1%, 64.3%, and 64.3% respectively. Retransplantation rate was 7%. A major morbidity occurred in four patients: one primary dysfunction, one hyperacute rejection due to ABO blood group-incompatibility requiring retransplantation, two arterial complications, and two biliary leakages. Our outcomes of emergency transplantation were similar to those reported by both the European and Spanish Liver Transplantation Registries, despite the small number of patients.
Surgical services are preparing to scale up in areas affected by COVID-19. This study aimed to evaluate the association between preoperative SARS-CoV-2 testing and postoperative pulmonary ...complications in patients undergoing elective cancer surgery.
This international cohort study included adult patients undergoing elective surgery for cancer in areas affected by SARS-CoV-2 up to 19 April 2020. Patients suspected of SARS-CoV-2 infection before operation were excluded. The primary outcome measure was postoperative pulmonary complications at 30 days after surgery. Preoperative testing strategies were adjusted for confounding using mixed-effects models.
Of 8784 patients (432 hospitals, 53 countries), 2303 patients (26.2 per cent) underwent preoperative testing: 1458 (16.6 per cent) had a swab test, 521 (5.9 per cent) CT only, and 324 (3.7 per cent) swab and CT. Pulmonary complications occurred in 3.9 per cent, whereas SARS-CoV-2 infection was confirmed in 2.6 per cent. After risk adjustment, having at least one negative preoperative nasopharyngeal swab test (adjusted odds ratio 0.68, 95 per cent confidence interval 0.68 to 0.98; P = 0.040) was associated with a lower rate of pulmonary complications. Swab testing was beneficial before major surgery and in areas with a high 14-day SARS-CoV-2 case notification rate, but not before minor surgery or in low-risk areas. To prevent one pulmonary complication, the number needed to swab test before major or minor surgery was 18 and 48 respectively in high-risk areas, and 73 and 387 in low-risk areas.
Preoperative nasopharyngeal swab testing was beneficial before major surgery and in high SARS-CoV-2 risk areas. There was no proven benefit of swab testing before minor surgery in low-risk areas.
