ABSTRACT
@#Objective To evaluate the safety, feasibility and short-term outcomes of single-direction gastric mobilization under 3D-laparoscopy in minimally invasive esophagectomy for the treatment of esophageal cancer. Methods From February 2018 to December 2019, 118 consecutive patients who underwent minimally invasive McKeown esophagectomy for esophageal squamous cell carcinoma in our hospital were included. There were 94 males and 24 females with an average age of 53.7 (41–77) years. They were divided into two groups based on the methods of gastric mobilization: a traditional dissociation (TD) group (n=55) and a single-direction mobilization (MD) group (n=63). The clinical data of the two groups were compared. Results Enbloc resection and a negative resection margin were obtained in all patients. There was no postoperative mortality or incision complication. The rate of postoperative complications was 22.9%. There was no significant difference in the spleen injury, gastric injury, conversion to open surgery, abdominal reoperation as well as cervical anastomotic leakage between the two groups (P>0.05). It took significantly less time in the MD group compared with the TD group (P<0.05). There was an obvious statistical difference in the incidence of gastric mobilization related complications between the MD group (1.6%, 1/63) and TD group (12.7%, 7/55, P<0.05). Conclusion Application of single-direction gastric mobilization under 3D-laparoscopy in minimally invasive esophagectomy for the treatment of esophageal cancer is safe and easy to perform with a satisfactory short-term outcome.
ABSTRACT
【Objective】 To investigate the clinical characteristics of COVID-19 induced deaths and analyze the causes of death. 【Methods】 This was a hospital-based, retrospective, observational cohort study involving hospitalized patients diagnosed with COVID-19 in People’s Hospital of Wuhan University during January 27 and February 25, 2020. The clinical data of identified patients who had died of COVID-19 were retrieved and reviewed. We analyzed the death causes and compared the changes in laboratory findings between patients before death and early onset to summarize the inherent clinical characteristics. 【Results】 We recorded a total of 21 deaths, 61.9% of which had occurred due to simple respiratory failure, followed by respiratory failure with myocardial injury (19%), respiratory failure with renal failure (9.5%), and respiratory failure with shock (9.5%). At the late time, lab test data indicated that white blood cells, D-dimer, amino-terminal brain natriuretic peptide precursors, and hypersensitive C-reactive protein significantly increased while counts of lymphosyte significantly decreased (P<0.05). 【Conclusion】 Continuous monitoring of cardiac function, renal function, and infection severity can assess the disease progression accurately. Moreover, timely intervention has a positive effect in reducing COVID-19 mortality.
ABSTRACT
Objective:To analyze the clinical characteristics and causes of death of 80 dead cases with confirmed coronavirus disease 2019 (COVID-19).Methods:The clinical data of 80 dead patients with COVID-19 who were admitted to Renmin Hospital of Wuhan University from January 11 to February 11, 2020 were retrospectively analyzed.The laboratory examination indexes (including white blood cells, lymphocytes, procalcitonin (PCT), lactic acid, D-dimmer, fibrinogen degradation products, N-terminal pro-brain natriuretic peptide (N-proBNP), ultra sensitive-troponin I, lactate dehydrogenase (LDH) and CD4 + T lymphocyte) of the patients at the time of admission were compared with the indexes at the last time before death. Statistical analysis was conducted by using paired t test or Wilcoxon′s signed rank test. Results:The median age was 72 years old of the 80 patients, and 78.75%(63/80) of them were older than 60 years. Thirty-six cases (45.00%) were severe and 44(55.00%) were critical at admission. Fifty-eight cases (72.50%) had underlying diseases. The common underlying diseases were hypertension, diabetes mellitus, coronary atherosclerotic heart disease, and chronic obstructive pulmonary disease. Comparing the patients′ first laboratory tests at admission with those before death, white blood cells increased (8.01(4.86, 12.29)×10 9/L vs 12.55(8.25, 17.66)×10 9/L), lymphocytes decreased (0.70(0.46, 0.88)×10 9/L vs 0.54(0.39, 0.75)×10 9/L), PCT increased (0.20(0.11, 0.74) μg/L vs 1.00(0.20, 1.99) μg/L), lactic acid increased (2.10(1.40, 3.10) mmol/L vs 3.10(2.60, 4.10) mmol/L), D-dimmer increased (4.33(0.97, 18.98) mg/L vs 15.29(5.17, 53.44) mg/L), fibrinogen degradation products increased (15.90(3.58, 76.60) mg/L vs 63.14(21.23, 110.67) mg/L), N-proBNP increased (1 078.00(347.35, 2 996.50) ng/L vs 3 439.50(1 576.00, 9 281.50) ng/L), ultra-sensitive troponin I increased (0.08(0.03, 0.17) μg/L vs 0.33(0.14, 2.47) μg/L), LDH increased (397.00(327.00, 523.50) U/L vs 624.00(481.00, 854.00) U/L) and CD4 + T lymphocyte decreased (137.00(104.00, 168.00)/μL vs 97.00(67.00, 128.00)/μL). The differences between the two groups were all statistically significant ( W=238.00, 1 053.50, 150.00, 152.00, 192.00, 190.00, 108.00, 57.00, 53.00 and 40.00, respectively, all P<0.05). All patients received antiviral and respiratory-support therapy and the main cause of death was respiratory failure caused by intractable hypoxemia and multiple organ failure. Among them, seven cases died in one day hospitalization, and 66 cases died in seven days hospitalization. Conclusions:Elderly patients with a variety of chronic underlying diseases have poor prognosis. It′s essential to pay more attention and deal with the above clinical characteristics at an early stage to improve the outcome of the COVID-19 patients.
ABSTRACT
Objective:To analyze the risk factors of fatal outcome in patients with severe COVID-19.Methods:The clinical characteristics of 107 patients with severe COVID-19 admitted in Renmin Hospital of Wuhan University from February 12 to March 12, 2020 were retrospectively analyzed. During the hospitalization 49 patients died (fatal group) and 58 patients survived (survival group). The clinical characteristics, baseline laboratory findings were analyzed using R and Python statistical software. The risk factors of fatal outcome in patients with severe COVID-19 were analyzed with multivariate logistic regression.Results:Univariate analysis showed that the two groups had statistically significant differences in age, clinical classification, dry cough, dyspnea and laboratory test indicators ( P<0.05 or <0.01). The random forest model was used to rank the significance of the statistically significant variables in the univariate analysis, and the selected variables were included in the binary logistic regression model. After stepwise regression analysis, the patient’s clinical type, age, neutrophil count, and the proportion of CD3 cells are independent risk factors for death in severe COVID-19 patients. Dry cough is an independent protective factor for the death of severe COVID-19 patients. Conclusion:COVID-19 patients with fatal outcome are more likely to have suppressed immune function, secondary infection and inflammatory factor storm. These factors may work together in severe patients, leading to intractable hypoxemia and multiple organ dysfunction and resulting in fatal outcome of patients. The study indicates that timely intervention and treatment measures against above factors may be effective to save the lives of patients with severe COVID-19.
ABSTRACT
The primary importance of magnetic resonance (MR) imaging in evaluating anal fistulas lies in its ability to demonstrate hidden areas of sepsis and secondary extensions in patients with fistula in ano. MR imaging is relatively expensive, so there are many healthcare systems worldwide where access to MR imaging remains restricted. Until recently, computed tomography (CT) has played a limited role in imaging fistula in ano, largely owing to its poor resolution of soft tissue. In this article, the different imaging features of the CT and MRI are compared to demonstrate the relative accuracy of CT fistulography for the preoperative assessment of fistula in ano. CT fistulography and MR imaging have their own advantages for preoperative evaluation of perianal fistula, and can be applied to complement one another when necessary.
