Background
Critical patients with the coronavirus disease 2019 (COVID-19), even those whose nucleic acid test results had turned negative and those receiving maximal medical support, have been noted to progress to irreversible fatal respiratory failure. Lung transplantation (LT) as the sole therapy for end-stage pulmonary fibrosis related to acute respiratory distress syndrome has been considered as the ultimate rescue therapy for these patients.
Methods
From February 10 to March 10, 2020, three male patients were urgently assessed and listed for transplantation. After conducting a full ethical review and after obtaining assent from the family of the patients, we performed three LT procedures for COVID-19 patients with illness durations of more than one month and extremely high sequential organ failure assessment scores.
Results
Two of the three recipients survived post-LT and started participating in a rehabilitation program. Pearls of the LT team collaboration and perioperative logistics were summarized and continually improved. The pathological results of the explanted lungs were concordant with the critical clinical manifestation, and provided insight towards better understanding of the disease. Government health affair systems, virology detection tools, and modern communication technology all play key roles towards the survival of the patients and their rehabilitation.
Conclusions
LT can be performed in end-stage patients with respiratory failure due to COVID-19-related pulmonary fibrosis. If confirmed positive-turned-negative virology status without organ dysfunction that could contraindicate LT, LT provided the final option for these patients to avoid certain death, with proper protection of transplant surgeons and medical staffs. By ensuring instant seamless care for both patients and medical teams, the goal of reducing the mortality rate and salvaging the lives of patients with COVID-19 can be attained.
Background:Surgical resection is generally considered the main curative treatment for intrahepatic biliary cystadenocarcinoma (IBCA) or suspected IBCAs, but controversy exists regarding the prognosis for IBCAs. This study aimed to describe the clinicopathological characteristics of IBCA and identify prognostic factors that may influence the survival of patients treated with surgical procedures.Methods:Thirty-four patients with histologically confirmed IBCA treated between January 2000 and June 2014 were included. The clinical characteristics of patients with IBCA were compared with those of 41 patients with intrahepatic biliary cystadenoma (IBC); factors that significant difference were analyzed for prognosis analysis of IBCA using multivariate/univariate Cox proportional hazards regression models. Survival curves were constructed using the Kaplan–Meier method and compared using the log-rank test.Results:IBCAs had a strong female predominance, and the most common presenting symptoms were abdominal pain or discomfort. Compared with IBCs, IBCAs occurred in older patients, in more male patients, and were associated statistically significant abnormal increase in alanine aminotransferase (P = 0.01) and total bilirubin (P = 0.04). Mural nodules were more frequently seen with IBCAs and may associate with malignancy. It was difficult to differentiate between IBC and IBCA based on laboratory examination and imaging findings. Although complete resection is recommended, enucleation with negative margins also achieved good outcomes. Median overall patient survival was 76.2 months; survival at 1, 3, and 5 years was 88.0%, 68.7%, and 45.8%, respectively. Radical resection and noninvasive tumor type were independent prognostic factors for overall survival.Conclusions:It remains difficult to distinguish between cystadenomas and cystadenocarcinomas based on laboratory examination and image findings. Complete resection is recommended for curative treatment, and patients should be closely followed postoperatively, particularly those with invasive tumors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
