Handling of the Covid-19 Pandemic and Its Effects on Bariatric Surgical Practice: Analysis of GENEVA Study Database

Obesity Surgery (2022)

Rishi Singhal Tom Wiggins Sjaak Pouwels Yashasvi Rajeev Brijesh Madhok

The coronavirus disease 2019 (COVID-19) pandemic led to a worldwide suspension of bariatric and metabolic surgery (BMS) services. The current study analyses data on patterns of service delivery, recovery of practices, and protective measures taken during the COVID-19 pandemic by bariatric teams.The current study is a subset analysis of the GENEVA study which was an international cohort study between 01/05/2020 and 31/10/2020. Data were specifically analysed regarding the timing of BMS suspension, patterns of service recovery, and precautionary measures deployed.A total of 527 surgeons from 439 hospitals in 64 countries submitted data regarding their practices and handling of the pandemic. Smaller hospitals (with less than 200 beds) were able to restart BMS programmes more rapidly (time to BMS restart 60.8 ± 38.9 days) than larger institutions (over 2000 beds) (81.3 ± 30.5 days) (p = 0.032). There was a significant difference in the time interval between cessation/reduction and restart of bariatric services between government-funded practices (97.1 ± 76.2 days), combination practices (84.4 ± 47.9 days), and private practices (58.5 ± 38.3 days) (p < 0.001). Precautionary measures adopted included patient segregation, utilisation of personal protective equipment, and preoperative testing. Following service recovery, 40% of the surgeons operated with a reduced capacity. Twenty-two percent gave priority to long waiters, 15.4% gave priority to uncontrolled diabetics, and 7.6% prioritised patients requiring organ transplantation.This study provides global, real-world data regarding the recovery of BMS services following the COVID-19 pandemic.

Recidivas de neurocriptococose pós-transplante hepático: relato de caso

Revista Neurociências (2022)

Leticia Scopel Miossi Carolina Vianna Barreto de Fraipont Matheus Dias Caprini Natalia Brito Feu Lívia Zardo Trindade

Relato de caso de dupla recidiva de neurocriptococose com o objetivo de divulgar informações e fomentar discussão sobre essa, que é a terceira infecção fúngica mais comum após transplante de órgãos sólidos e que é de difícil manejo e com literatura escassa. Alguns pacientes apresentam resultados desfavoráveis a despeito da instituição de terapia antifúngica, como morte prematura devido às complicações da doença, controle tardio da infecção ou até mesmo não controle da infecção apesar da terapia instituída. Casos refratários apresentam prognóstico pior.

Comparison of results on the use of extended criteria liver doners for transplants in Espírito Santo

Revista do Colégio Brasileiro de Cirurgiões (2021)

ANTONIO CARLOS LUGON FERREIRA-JR Gustavo Peixoto Soares Miguel Iara Moscon Isaac Walker de Abreu Juliete Borel de Oliveira Silva Aguiar

ABSTRACT Introduction: liver Transplantation is currently the treatment of choice for several terminal liver diseases. Despite the increase in performed transplants, the waiting lists continue to increase. In order to expand the supply of organs, transplantation teams have started to use previously rejected livers for transplants because of an increased risk of unfavorable outcomes. Objective: to evaluate the use of livers of expanded criterion donators. Methods: retrospective study of medical records. The livers were classified as normal or expanded criteria. The groups were divided in low and high MELD. A multivariate analysis was performed through logistic regression. Results: there was no statistical difference regarding early, late and global mortality between the groups. Decreased survival was observed in patients with high MELD (higher or equal to 20) when they received grafts from expanded criterion donators. The association between the occurrence of cardiorespiratory arrest and presence of elevated total bilirubin in donators was associated with higher mortality rates in expanded criterion livers. Conclusion: the overall results are similar, but expanded criteria liver donators was associated with higher mortality in patients with high MELD.

Benign obstruction of the common hepatic duct (Mirizzi syndrome): diagnosis and operative management

Arquivos de Gastroenterologia (2005)

Jaques Waisberg Adriano Corona Isaac Walker de Abreu José Francisco de Matos Farah Renato Arioni Lupinacci

Mirizzi syndrome is a rare complication of prolonged cholelithiasis, characterized by narrowing of the common hepatic duct due to mechanical compression and/or inflammation due to biliary calculus impacted in the infundibula of the gallbladder or in the cystic duct.To describe a series of eight consecutive patients with Mirizzi syndrome, at a single institution, submitted to surgical treatment and to comment on their aspects with emphasis on the diagnosis and treatment.Four women and four men, with a mean age of 61.6 years (42 to 82 years), presenting Mirizzi syndrome were operated between 1997 and 2003. The following items were evaluated: clinical presentation, laboratory results, preoperative evaluation, operative findings, presence of choledocholithiasis, type of Mirizzi syndrome according to the classification by Csendes, choice of operative procedures, and complications.The most frequent symptoms were abdominal pain (87.5%) and jaundice (87.5%). All the patients presented altered hepatic function tests. The diagnosis of Mirizzi syndrome was intra-operative in seven (87.5%) patients, and preoperative in one (12.5%). Cholecystocholedochal fistula associated with choledocholithiasis was observed in three (37.5%) cases. Mirizzi syndrome was classified as Csendes type I in five (62.5%) patients, type II in one (12.5%), type III in one (12,5%) and type IV in another (12.5%). Cholecystectomy, as an isolated surgical procedure, was performed in four (50.0%) patients. One (12.5%) patient was submitted to partial cholecystectomy and closure of the fistulous orifice with the central part of the infundibula. Two (25.0%) patients were submitted to cholecystectomy and side-to-side choledochoduodenostomy and another (12.5%) to side-to-side choledochoduodenostomy remaining the gallbladder in situ. Seven (87.5%) patients had an uneventful recovery and were discharged in good conditions. One (12.5%) patient presented a postoperative sepsis due to a sub-hepatic abscess, and was reoperated. There was no operative mortality.The preoperative diagnosis of Mirizzi syndrome is difficult and an awarded suspicion is necessary to avoid lesions of the biliary tree. The problem may only become evident during the operation due to firm adherences around Calot's triangle. The success of the treatment is related to a precocious recognition of the condition, even at the time of surgery, and adapting the management considering to the individual characteristics of each case.
