H. pylori infection did not affect the rate of early complications after sleeve gastrectomy. This suggests that H. pylori screening or eradication policy is not essential for asymptomatic candidates who have undergone sleeve gastrectomy.
Background The incidence of the highly morbid and potentially lethal gangrenous cholecystitis was reportedly increased during the COVID-19 pandemic. The aim of the ChoCO-W study was to compare the clinical findings and outcomes of acute cholecystitis in patients who had COVID-19 disease with those who did not. Methods Data were prospectively collected over 6 months (October 1, 2020, to April 30, 2021) with 1-month follow-up. In October 2020, Delta variant of SARS CoV-2 was isolated for the first time. Demographic and clinical data were analyzed and reported according to the STROBE guidelines. Baseline characteristics and clinical outcomes of patients who had COVID-19 were compared with those who did not. Results A total of 2893 patients, from 42 countries, 218 centers, involved, with a median age of 61.3 (SD: 17.39) years were prospectively enrolled in this study; 1481 (51%) patients were males. One hundred and eighty (6.9%) patients were COVID-19 positive, while 2412 (93.1%) were negative. Concomitant preexisting diseases including cardiovascular diseases (p < 0.0001), diabetes (p < 0.0001), and severe chronic obstructive airway disease (p = 0.005) were significantly more frequent in the COVID-19 group. Markers of sepsis severity including ARDS (p < 0.0001), PIPAS score (p < 0.0001), WSES sepsis score (p < 0.0001), qSOFA (p < 0.0001), and Tokyo classification of severity of acute cholecystitis (p < 0.0001) were significantly higher in the COVID-19 group. The COVID-19 group had significantly higher postoperative complications (32.2% compared with 11.7%, p < 0.0001), longer mean hospital stay (13.21 compared with 6.51 days, p < 0.0001), and mortality rate (13.4% compared with 1.7%, p < 0.0001). The incidence of gangrenous cholecystitis was doubled in the COVID-19 group (40.7% compared with 22.3%). The mean wall thickness of the gallbladder was significantly higher in the COVID-19 group [6.32 (SD: 2.44) mm compared with 5.4 (SD: 3.45) mm; p < 0.0001]. Conclusions The incidence of gangrenous cholecystitis is higher in COVID patients compared with non-COVID patients admitted to the emergency department with acute cholecystitis. Gangrenous cholecystitis in COVID patients is associated with high-grade Clavien-Dindo postoperative complications, longer hospital stay and higher mortality rate. The open cholecystectomy rate is higher in COVID compared with non -COVID patients. It is recommended to delay the surgical treatment in COVID patients, when it is possible, to decrease morbidity and mortality rates. COVID-19 infection and gangrenous cholecystistis are not absolute contraindications to perform laparoscopic cholecystectomy, in a case by case evaluation, in expert hands. Graphical abstract
Background:A thyroidectomy can be performed via a cervical incision in most patients with retrosternal goiter.Aims:To investigate the correlation between the volume of the mediastinal portion of the thyroid gland and the need for an extra-cervical approach for retrosternal goiter.Study Design:Diagnostic accuracy study.Methods:The measurement of craniocaudal length and the volume of the mediastinal component of the thyroid gland on computerised tomography images was performed in 47 patients with retrosternal goiter. Of these 47 patients, 8 (17%) required an extra-cervical approach and were classified as group 1, and 39 (83%) patients that required a cervical incision were classified as group 2. Receiver operating characteristic analysis was performed to determine the cut-off value for the craniocaudal length and the volume of the mediastinal thyroid mass, which significantly correlated with an extra-cervical approach for retrosternal goiter.Results:Reoperative surgery was significantly more frequent in group 1 than in group 2 (50% vs 13%; p=0.03). The craniocaudal length of the mediastinal thyroid gland was significantly longer in group 1 than in group 2 (77±11 mm vs 31±21 mm, respectively; p=0.0001). The volume of the mediastinal component was significantly larger in group 1 compared to group 2 (264±106 cm3 vs 40±41 cm3, respectively; p=0.0001). The receiver operating characteristic curve of craniocaudal length and the volume of the mediastinal component identified ≥66 mm and ≥162 cm3 as the cut-off values with the maximum accuracy, respectively. The craniocaudal length of the thyroid mass below the thoracic inlet ≥66 mm or a volume of the mediastinal portion ≥162 cm3 were significantly associated with an extra-cervical approach (p=0.0001). For predicting an extra-cervical approach, the sensitivity, positive predictive value and negative predictive value of the cut-off value for craniocaudal length was 87.5%, 64% and 97%, respectively. For predicting an extra-cervical approach, the sensitivity, positive predictive value and negative predictive value of the cut-off values for the mediastinal volume were 100%, 89% and 100%, respectively.Conclusion:A thyroid volume of ≥162 cm3 extending below the thoracic inlet was a significant determining factor for an extra-cervical approach, with a negative predictive value for the extra-cervical approach of 100% for retrosternal goiter with smaller volumes. Further studies with an increased number of patients are needed to determine the value of volumetric analysis of retrosternal goiter to predict the need for an extra-cervical approach in retrosternal goiter.
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.
