Impact of Perioperative Steroid Administration in Patients Undergoing Major Hepatectomy with Extrahepatic Bile Duct Resection: A Randomized Controlled Trial.

BACKGROUND: To date, five randomized controlled trials have assessed the clinical benefit of perioperative steroid administration in hepatectomy; however, all of these studies involved a substantial number of 'minor' hepatectomies. The benefit of steroid administration for patients undergoing 'complex' hepatectomy, such as major hepatectomy with extrahepatic bile duct resection, is still unclear. This study aimed to evaluate the clinical benefit of perioperative steroid administration for complex major hepatectomy. METHODS: Patients with suspected hilar malignancy scheduled to undergo major hepatectomy with extrahepatic bile duct resection were randomized into either the control or steroid groups. The steroid group received hydrocortisone 500 mg immediately before hepatic pedicle clamping, followed by hydrocortisone 300 mg on postoperative day (POD) 1, 200 mg on POD 2, and 100 mg on POD 3. The control group received only physiologic saline. The primary endpoint was the incidence of postoperative liver failure. RESULTS: A total of 94 patients were randomized to either the control (n = 46) or steroid (n = 48) groups. The two groups had similar baseline characteristics; however, there were no significant differences between the groups in the incidence of grade B/C postoperative liver failure (control group, n = 8, 17%; steroid group, n = 4, 8%; p = 0.188) and other complications. Serum bilirubin levels on PODs 2 and 3 were significantly lower in the steroid group than those in the control group; however, these median values were within normal limits in both groups. CONCLUSION: Perioperative steroid administration did not reduce the risk of postoperative complications, including liver failure following major hepatectomy with extrahepatic bile duct resection.

Saturation of Percutaneous Oxygen Decreases with Meal Consumption in Patients with Acute Pneumonia.

OBJECTIVE: This study aimed to investigate how respiratory status may be affected during meal consumption in patients with acute pneumonia, mainly aspiration pneumonia, using percutaneous oxygen saturation (SpO2) and pulse rate (PR) measurements. METHODS: We recruited 44 inpatients at the Towada City Hospital and divided them into 'pneumonia' and 'control' groups. Generalized linear mixed effects model was used for analysis. The pneumonia group comprised 22 patients (mean age 81.2 ± 7.0 years, body mass index [BMI] 21.1 ± 4.0 kg/m2) with 1-3 points A-DROP scores. The control group comprised 22 patients (mean age 80.5 ± 4.9 years, BMI 20.9 ± 2.9 kg/m2) with no obvious respiratory diseases. SpO2 and PR were measured 30 min before, during, and 30 min after meals. RESULTS: SpO2 was significantly lower during meals in the pneumonia group (-1.60%; 95% confidence interval = -2.76 to -0.44). There were no significant changes in PR during or after meals in the pneumonia group. CONCLUSIONS: This study suggests pneumonia may worsen respiratory status during meal intake. Patients with pneumonia may be unable to eat adequately due to worsened oxygenation during meals, even in the absence of aspiration. Therefore, it is important to observe whether there is a decrease in respiratory status during meals.

Assessing the Complicated Venous Hemodynamics and Therapeutic Outcomes of Budd-Chiari Syndrome with Respiratory-gated 4D Flow MR Imaging During the Expiratory and Inspiratory Phases.

A man in his 50s with Budd-Chiari syndrome diagnosed with the suprahepatic inferior vena cava (IVC) obstruction on CT was assessed using 4D Flow MRI before and after balloon angioplasty. 4D Flow MRI acquired in two respiratory phases, depicted complex hemodynamic and respiratory variability, and a jet stream at the narrowed channel of the membranous IVC. Post-interventional 4D Flow MRI showed that the IVC blood flow increased with corrected flow directions in the infrarenal IVC.

Complete Lateral Positioning Enabled Feeding in a Patient with Aspiration Pneumonia.

The complete lateral position can be used to widen the lateral pharynx in a direction that facilitates swallowing and reduces the risk of aspiration, even if the patient is unable to eat in the sitting position. Here, we report a case of aspiration pneumonia in a patient who was unable to eat in the sitting position after swallowing endoscopy, but was able to eat in the complete lateral position. By employing complete lateral positioning, more patients may be able to continue oral intake.

Acute Cholecystitis, Sepsis, and Disseminated Intravascular Coagulation Caused by Edwardsiella tarda in an Elderly Woman.

Edwardsiella tarda is a gram-negative bacillus associated with gastrointestinal diseases. It is rarely responsible for sepsis; however, the fatality is very high. Only two cases of E. tarda infections in patients over 90 years of age have been reported; these are not cases of sepsis associated with acute cholecystitis. We report a case of acute cholecystitis, sepsis, and disseminated intravascular coagulation (DIC) caused by E. tarda in a super-elderly woman aged over 90 years. There could be a possibility for recovery from sepsis and DIC if antimicrobial treatment responsiveness is ensured in the super-elderly.
