Septic shock caused by emphysematous hepatitis complicated with intracranial infection

Purpose

Emphysematous hepatitis is an uncommon and life-threatening hepatic infection, characterized by the presence of gas within the liver and high mortality. There are few reports of this condition.

Method

We report a case of septic shock caused by emphysematous hepatitis complicated with intracranial infection, and review the current literature on emphysematous hepatitis.

Results

A 57-year-old male with uncontrolled diabetes mellitus developed emphysematous hepatitis complicated with intracranial infection, which progressed to septic shock. The patient was treated with antibiotics and received percutaneous liver puncture drainage early and was discharged preferably in remission. From the literature review, we found 16 previously published cases of emphysematous hepatitis.

Conclusion

Given our experience and the literature review, percutaneous liver puncture drainage or surgical treatment in the early stage may be beneficial to patients with emphysematous hepatitis.

Radiology and Non-operative Management of Emphysematous Infections of the Pancreas, Gallbladder, and Urinary System

Emphysematous abdominal infections are regarded as potentially life-threatening conditions and benefit from appropriate radiological imaging for timely diagnosis and treatment planning. A 70-year-old non-diabetic male presented with an acute abdomen and had computed tomography diagnosed emphysematous pancreatitis, cholecystitis, and pyelonephritis. Treatment included broad-spectrum antimicrobial therapy. Ultrasound-guided percutaneous drain placement into the peri-pancreatic collection permitted culture-directed antibiotic therapy and continued drainage of the purulent collection. He achieved non-operative management of the first reported case of simultaneous emphysematous infections of the pancreas, gallbladder, and urinary system. His imaging and non-operative management are described.

Emphysematous hepatitis: A rare fatal case

Emphysematous hepatitis (EH) is a rare, insidious, rapidly progressing, and often fatal liver infection characterized by diffuse air in the liver parenchyma. While infectious parenchymal diseases can affect many intra-abdominal organs such as the kidney, urinary bladder, gall bladder, stomach, and pancreas, liver involvement is uncommon. Few cases of EH have been reported in the literature, with only four successfully treated. Diagnosis involves patient history, clinical and laboratory findings, and computed tomography. Treatment is challenging and requires close monitoring. This case report aims to enhance the understanding of EH's diagnosis and treatment in medical literature.

Emphysematous Pancreatitis as a Life-Threatening Condition: A Case Report and Review of the Literature

Emphysematous pancreatitis represents the presence of gas within or around the pancreas on the ground of necrotizing pancreatitis due to superinfection with gas-forming bacteria. This entity is diagnosed on clinical grounds and on the basis of radiologic findings. Computed tomography is the preferred imaging modality used to detect this life-threating condition. The management of emphysematous pancreatitis consists of conservative measures, image-guided percutaneous catheter drainage or endoscopic therapy, and surgical intervention, which is delayed as long as possible and undertaken only in patients who continue to deteriorate despite conservative management. Due to its high mortality rate, early and prompt recognition and treatment of emphysematous pancreatitis are crucial and require individualized treatment with the involvement of a multidisciplinary team. Here, we present a case of emphysematous pancreatitis as an unusual occurrence and discuss disease features and treatment options in order to facilitate diagnostics and therapy.

Gas Density Within the Pancreas: A Case of Emphysematous Pancreatitis

Teaching Point: Computed tomography is the imaging modality of choice to detect the presence of gas within or around the pancreas in emphysematous pancreatitis.

Diagnostic and Management of Emphysematous Hepatitis with Emphasis on Biopathology

Emphysematous hepatitis is a rare infectious disease, which corresponds to the presence of gas in the liver, without collection and after exclusion of vascular origin. This entity belongs to the group of emphysematous infections, whose physiopathology seems to be linked to the presence of unbalanced diabetes and to bacterial fermentation, leading to the production of gas within the liver parenchyma. Very few cases of emphysematous hepatitis have been described in the literature, and most of them had a rapidly fatal course. In this manuscript, we report the case of a 59-year-old man with emphysematous hepatitis due to wild-type Klebsiella pneumoniae that was successfully managed by surgery, and we perform a review of the literature to describe the clinical and biopathological aspects of this rare hepatic disease. Our manuscript underlines the need to perform biological and histopathological sampling to better understand the pathophysiology of this rare entity. The causes and mechanisms of emphysematous hepatitis, which seem to be multiple, lead us to believe that it is a syndrome rather than a simple infectious disease.

Pneumatosis: Appearances on CT Imaging

BACKGROUND

Pneumatosis is a general term used to designate the presence of spontaneous air or gas leaks into the body's compartments.

PURPOSE

In this paper, we provide an overview of gas originating from different sites and present the most common routes by which air may escape free to surrounding or distant tissues.

METHODS

On the basis of 45 interesting clinical cases, we discuss the CT imaging characteristics of thoracic and spinal pneumatosis, better known as pneumomediastinum and pneumorrhachis. In addition, we present craniocervical pneumatosis manifesting as subcutaneous emphysema.

RESULTS

Isolated pneumatosis was diagnosed in 12 (27%) of the 45 patients, manifesting as craniocervical free air or pneumoperitoneum. In 28 (62%) patients with pneumomediastinum, 12 (43%) had concomitant pneumothorax. Soft tissue emphysema was seen in 24 (52%) patients. One of the patients with generalized pneumatosis had craniocervical and extensive soft tissue emphysema, in conjunction with pneumomediastinum, pneumothorax, and pneumoperitoneum. Intraspinal pneumatosis was always coupled with pneumomediastinum.

CONCLUSION

Pneumatosis may not be as uncommon as it seems, and indeed, this condition may need to be recognized early as it can be an alarming sign of serious pathology.

Air in gallbladder: Emphysematous cholecystitis or else?

Gas in gallstones represents a rare but well described radiological finding. Other causes of gas in gallbladder include biliary-enteric fistula, sphincterotomy, gas forming organisms cholangitis. However, gas in gallbladder raises suspicion of emphysematous cholecystitis which necessitates prompt diagnosis and management due to its rapid clinical course and high mortality rate.

Clostridium perfringens gas gangrene caused by closed abdominal injury: A case report and review of the literature

BACKGROUND

Abdominal Clostridium perfringens (C. perfringens) gas gangrene is a rare infection that has been described in the literature as most frequently occurring in postoperative patients with open trauma. Intra-abdominal gas gangrene caused by C. perfringens infection after closed abdominal injury is extremely rare, difficult to diagnose, and progresses rapidly with high mortality risk. Here, we report a case of C. perfringens infection caused by closed abdominal injury.

CASE SUMMARY

A 54-year-old male suffered multiple intestinal tears and necrosis after sustaining an injury caused by falling from a high height. These injuries and the subsequent necrosis resulted in intra-abdominal C. perfringens infection. In the first operation, we removed the necrotic intestinal segment, kept the abdomen open and covered the intestine with a Bogota bag. A vacuum sealing drainage system was used to cover the outer layer of the Bogota bag, and the drainage was flushed under negative pressure. The patient was transferred to the intensive care unit for supportive care and empirical antibiotic treatment. The antibiotics were not changed until the results of bacterial culture and drug susceptibility testing were obtained. Two consecutive operations were then performed due to secondary intestinal necrosis. After three definitive operations, the patient successfully survived the perioperative period. Unfortunately, he died of complications related to Guillain-Barre syndrome 75 d after the first surgery. This paper presents this case of intra-abdominal gas gangrene infection and analyzes the diagnosis and treatment based on a review of current literature.

CONCLUSION

When the intestines rupture leading to contamination of the abdominal cavity by intestinal contents, C. perfringens bacteria normally present in the intestinal tract may proliferate in large numbers and lead to intra-abdominal infection. Prompt surgical intervention, adequate drainage, appropriate antibiotic therapy, and intensive supportive care comprise the most effective treatment strategy. If the abdominal cavity is heavily contaminated, an open abdominal approach may be a beneficial treatment.

Early-onset emphysematous pancreatitis indicates poor outcomes in patients with infected pancreatic necrosis

BACKGROUND

Emphysematous pancreatitis (EP) is a subtype of infected pancreatic necrosis (IPN) characterized by presence of gas in (peri)pancreatic necrosis. However, the impacts of EP on outcomes of IPN are still controversial.

METHODS

A prospective database of consecutive patients with IPN in a tertiary hospital was post-hoc analyzed. Patients were assigned to EP and non-EP groups to perform a comprehensive comparison.

RESULTS

A total of 178 patients with IPN were enrolled and the overall mortality was 30.9%. EP accounted for 20.8% (n = 37) of cases and was significantly associated with higher incidences of Escherichia coli (45.9 versus 18.4%, P = 0.001) and Klebsiella pneumoniae (56.8 versus 33.3%, P = 0.009) infection. There was scarcely any disparity in clinical characteristics and outcomes between IPN patients with and without EP. However, patients with early-onset EP defined as air bubble signs occurring within 2 weeks from disease onset were significantly older and have higher prevalence of history of diabetes, and they were also associated with significantly higher mortality (57.1 versus 8.7%, P = 0.015) compared with late-onset patients.

CONCLUSIONS

The clinical outcomes of EP might be like those of non-emphysematous infection. However, when EP occurs within 2 weeks from disease onset, it is highly lethal.
