Acalculous Cholecystitis as a Complication of Primary Epstein-Barr Virus Infection: A Case-Based Scoping Review of the Literature.

Primary Epstein-Barr virus (EBV) infection manifests with diverse clinical symptoms, occasionally resulting in severe complications. This scoping review investigates the rare occurrence of acute acalculous cholecystitis (AAC) in the context of primary EBV infection, with a focus on understanding its prevalence, clinical features, and underlying mechanisms. The study also explores EBV infection association with Gilbert syndrome, a condition that potentially exacerbates the clinical picture. Additionally, a case report of an 18-year-old female presenting with AAC and ascites secondary to EBV infection enhances the review. A comprehensive literature review was conducted, analyzing reported cases of AAC secondary to EBV infection. This involved examining patient demographics, clinical presentations, laboratory findings, and outcomes. The search yielded 44 cases, predominantly affecting young females. Common clinical features included fever, cervical lymphadenopathy, tonsillitis/pharyngitis, and splenomegaly. Laboratory findings highlighted significant hepatic involvement. The review also noted a potential link between AAC in EBV infection and Gilbert syndrome, particularly in cases with abnormal bilirubin levels. AAC is a rare but significant complication of primary EBV infection, primarily observed in young females, and may be associated with Gilbert syndrome. This comprehensive review underscores the need for heightened clinical awareness and timely diagnosis to manage this complication effectively.

Is conservative management a safe approach for patients with acute acalculous cholecystitis presenting with an acute abdomen?

Patients with acute acalculous cholecystitis (AAC) often present with acute abdominal symptoms. However, recent clinical studies have suggested that some patients with AAC and an acute abdomen, especially when caused by viruses or rheumatic disease, may not require cholecystectomy and that conservative treatment is adequate. Whether cholecystectomy is superior to conservative treatment for patients with AAC presenting with a severe acute abdomen is still uncertain. This was a case series study of AAC-related literature published between 1960 and 2022. In total, 171 cases (104 viral infection-associated AAC and 67 rheumatic disease-associated AAC) were included. The prognoses of patients receiving cholecystectomy or conservative treatment were compared. To account for confounding factors, etiological stratification and logistic regression were performed. The prognosis was similar for patients undergoing cholecystectomy and conservative treatment (P value .364), and virus infection-associated AAC had a better prognosis than rheumatic disease-associated AAC (P value .032). In patients with AAC caused by viruses or rheumatic disease, the acute abdomen can be adequately managed by conservative treatment of the underlying etiology and does not mandate surgical intervention.

Cholecystoenteric Stent-Related Complications: Rendering the Inoperable Patient Operable.

INTRODUCTION: Cholecystoenteric stenting is an alternative treatment for cholecystitis. However, complications with this approach can render a need for surgical intervention. METHODS: A case series of three patients undergoing surgery for a cholecystoenteric stent-related complication. RESULTS: Patient 1 was a 42-year-old male with history of lung transplant who had a cholecystoenteric stent placed for acalculous cholecystitis. One year later the stent became occluded with return of symptoms. Endoscopic replacement failed. A laparoscopic cholecystectomy with modified Graham patch was performed. Patient 2 is a 73-year-old female with acalculous cholecystitis in the setting of metastatic colon cancer on FOLFOX. Antibiotic treatment failed. A cholecystoenteric stent was attempted, but the stent dislodged during deployment. The fistula tract was clipped, and a percutaneous cholecystostomy drain was placed, which noted a leak at the gallbladder infundibulum. The patient deteriorated clinically and was taken emergently for an open cholecystectomy. Patient 3 was a 71-year-old male with history of ischemic cardiomyopathy who had a cholecystogastric stent placed for necrotizing gallstone pancreatitis. The stent migrated into the gastrointestinal tract and he developed post-prandial pain. A cholecystectomy and modified Graham patch repair of the gastrotomy was performed. This failed as the gastrotomy was too close to the pylorus. He underwent re-operation with Heineke-Mikulicz pyloroplasty. All patients recovered without any cardiopulmonary complications. CONCLUSION: With the increasing utility of cholecystoenteric stents, surgeons should be aware of the complications and have a plan for managing the duodenotomy or gastrotomy. Shared-medical decision-making involving surgeons should be applied when placing these stents.

Acalculous cholecystitis is a common extrahepatic manifestation of hepatitis E and suggests a more serious condition.

BACKGROUND: This study aimed to understand the incidence and clinical significance of acalculous cholecystitis in patients with acute hepatitis E (HE). PATIENTS AND METHODS: A single center enrolled 114 patients with acute HE. All patients underwent imaging of the gallbladder, and patients with gallstones and cholecystectomy were excluded. RESULTS: Acalculous cholecystitis was found in 66 patients (57.89%) with acute HE. The incidence in males was 63.95%, which was significantly higher than in females (39.29%) (P = 0.022). The mean length of hospital stay and the incidence of spontaneous peritonitis in patients with cholecystitis (20.12 ± 9.43 days and 9.09%, respectively) were significantly higher than those in patients without cholecystitis (12.98 ± 7.26 days and 0%, respectively) (P < 0.001 and P = 0.032). Albumin, total bile acid, bilirubin, cholinesterase, and prothrombin activity in patients with cholecystitis were significantly inferior to those in patients without cholecystitis (P < 0.001, P < 0.001, P < 0.001, P < 0.001 and P = 0.003, respectively). After correction by multivariate analysis, albumin and total bile acid were found to be closely related to acalculous cholecystitis in HE. CONCLUSION: Acalculous cholecystitis is very common in patients with acute HE, and may serve as a predictor of increased peritonitis, synthetic decompensation, and longer hospital stay.

A rare case of acute acalculous cholecystitis secondary to hantavirus infection with renal syndrome.

Hantaviruses are single-stranded RNA viruses. They are transmitted to humans by rodents and insectivore hosts. Some Hantavirus subtypes are the causative agents of haemorrhagic fever with renal syndrome (HFRS), which is characterized by fever, thrombocytopenia, and acute kidney injury. Hantavirus infection is difficult to diagnose due to its non-specific clinical symptoms. Causes of acalculous cholecystitis are severe trauma or burn, surgery, long-term starvation and some viral infections. It is very rare for Hantavirus to cause acute acalculous cholecystitis. The treatment of acute acalculous cholecystitis is usually directed towards its symptoms. A 22-year-old male forest worker was admitted to our emergency outpatient clinic with the complaints of fatigue, oliguria, fever, abdominal pain and vomiting. After the clinical and laboratory examinations, HFRS and acute cholecystitis secondary to Hantavirus infection were diagnosed. The patient's condition and clinical findings improved after supportive treatment. Hantavirus infection should be considered in patients with acute kidney injury, cholecystitis and thrombocytopenia (Fig. 2, Ref. 10). Keywords: Hantavirus, acute kidney injury, acalculous cholecystitis, thrombocytopeni.

ANOTHER FACE OF EPSTEIN-BARR VIRUS INFECTION: ACUTE ACALCULOUS CHOLECYSTITIS WITH CHOLESTASIS IN A PREVIOUSLY HEALTHY FIVE-YEAR-OLD GIRL WITH PRIMARY INFECTION.

Acute acalculous cholecystitis (AAC) is a rare disease, particularly in children. The clinical and laboratory presentation of AAC is variable. The diagnosis is based on radiological criteria. AAC is an atypical and rare complication of Epstein-Barr virus (EBV) infection, therefore we present a girl with AAC and cholestasis due to EBV primary infection. Conservative treatment and careful monitoring was followed by clinical, radiological and laboratory improvement, and finally complete recovery. Our aim was to highlight the importance of recognizing AAC as a differential diagnosis in children with abdominal pain and/or acute cholestasis.

Obstructive jaundice due to acute acalculous cholecystitis: 'Mirizzi-like syndrome'.

A 78 year-old female status post subarachnoid haemorrhage developed abdominal pain and obstructive jaundice. CT scan showed acute cholecystitis and dilation of the intrahepatic ducts. Endoscopic retrograde cholangiography revealed hepatic duct stenosis due to compression by an enlarged gallbladder. No stones were seen in the common hepatic duct and the cystic duct was patent. An endoscopic retrograde biliary drain was placed to relieve the obstructive jaundice due to acute acalculous cholecystitis. Percutaneous transhepatic drainage was performed to treat the acute acalculous cholecystitis. Hepatic duct stenosis was improved on endoscopic retrograde cholangiography performed 19 days after percutaneous transhepatic drainage. It may be reasonable to treat 'Mirizzi-like syndrome' non-operatively.

A Recurrent Case of Adult-onset Still's Disease with Concurrent Acalculous Cholecystitis and Macrophage Activation Syndrome/Hemophagocytic Lymphohistiocytosis Successfully Treated with Combination Immunosuppressive Therapy.

We herein report the case of 21-year-old female diagnosed with adult-onset Still's disease (AOSD) three years earlier who presented with fever and right upper abdominal pain. She was diagnosed with acute acalculous cholecystitis (AAC) based on hepatic dysfunction, elevated C-reactive protein, and gallbladder wall thickening on abdominal ultrasound. Based on the presence of pancytopenia, hyperferritinemia, and hemophagocytosis by a bone marrow examination, she was diagnosed with macrophage activation syndrome (MAS)/hemophagocytic lymphohistiocytosis (HLH) which was refractory to glucocorticoid pulse therapy. The combination of intravenous cyclosporine A with glucocorticoids was able to successfully control the disease activity of AOSD-related AAC and MAS/HLH.

Desarrollo de enfermedades concomitantes en pacientes críticos con COVID-19 / Development of concomitant diseases in COVID-19 critically ill patients

Puede ser necesaria una reflexión sobre cuál es el mejor abordaje para las enfermedades agudas concomitantes que pueden desarrollar los pacientes críticos con COVID-19. Estos requieren una sospecha diagnóstica y un tratamiento precoz, basados en el trabajo de equipos multidisciplinares. Presentamos dos casos de enfermedades concomitantes en pacientes con COVID-19. Un paciente diagnosticado de COVID-19 con buena evolución respiratoria que tras extubación presentó una colecistitis acalculosa y un paciente con neumonía por COVID-19 que presentó una sobreinfección con neumonía necrotizante, cuyo primer síntoma fue hemoptisis y fue finalmente tratado con embolización arterial por radiología intervencionista

It may be necessary a consideration about the best approach to the acute concomitant problems that critical COVID-19 patients can develop. They require a rapid diagnosis and an early treatment by a multidisciplinary team. As a result, we would like to describe two clinical cases a patient with diagnosis of COVID-19 pneumonia with good respiratory evolution that, after extubation suffered an acalculous cholecystitis and a patient with COVID-19 pneumonia that suffered an overinfection with necrotising pneumonia that presented with haemoptysis and was finally treated with arterial embolisation by the interventional radiologist's team

Multiple Myeloma Plasmacytoid Infiltration of the Gallbladder Presenting as Acute Cholecystitis.

Secondary distal plasmacytoma that arise from multiple myeloma is a common hematological malignancy that manifests in later stages of the disease. These plasmacytomas are known to cause extensive systemic organ damage. When extramedullary plasmacytomas reach the gallbladder or biliary ducts, expansion can mimic acute acalculous cholecystitis or cholangiocarcinoma. We report a case of a 56-year-old female with a history of aggressive course IgA κ chain multiple myeloma who presented with right upper quadrant abdominal pain with nausea and vomiting for one week duration. Her laboratory panel revealed liver function tests consistent with gallbladder etiology. Abdominal ultrasound and CT showed no evidence of cholelithiasis precluding to acute acalculous cholecystitis. Initial medical management did not show any improvement. A robotic cholecystectomy was performed, and a pathology review of the specimen found a neoplastic stricture of the gallbladder fundus, the histological evaluation of which revealed plasmacytoid cells originating from her primary multiple myeloma diagnosis. The patient's condition declined following surgery, postoperative presentation included metastatic liver thrombosis mimicking cholangiocarcinoma and the patient later expired with palliative care.

Acute Acalculous Cholecystitis-Associated Bacteremia Has Worse Outcome.

Background: Acute acalculous cholecystitis (AAC) is an inflammation of the gallbladder without gallstones in the setting of critical illness. It represents 2%-15% of acute cholecystitis (AC) cases. Bacteremia is associated with increased morbidity and mortality rates in patients in the intensive care unit (ICU). The incidence of bacteremia in acute calculous cholecystitis (ACC) has been described; however, the incidence of bacteremia in AAC has not been reported. We hypothesized that patients with AAC have higher bacteremia rates, leading to worse outcomes than in those with ACC. Methods: A prospectively collected acute care surgery (ACS) institutional database of patients treated from 2008 through 2018 was queried for patients having ACC using International Classification of Diseases (ICD) 9 and 10 codes. Demographics, microbiology findings, and outcomes were extracted. Only patients with positive blood cultures were included in the study. We defined two cohorts: AAC with bacteremia and ACC with bacteremia. The Student t-test was used for continuous variables and the χ2 and Fisher exact tests for categorical variables. Multivariable regression was applied, and statistical significance was set at p < 0.05. Results: Of 323 patients with AC, 57 (17.6%) had AAC and 266 (82.4%) had ACC. Of the 19 patients who had a blood culture, 11 (57.8%) were positive. Patients with positive blood cultures had a mean age of 56.7 ± 15.3 years and a mean Body Mass Index (BMI) of 26.7 ± 4.9. The incidence of bacteremia was significantly higher in AAC (n = 6; 10.5% versus n = 5; 1.9 %; p = 0.005), although the time between admission and diagnosis of bacteremia was similar in the two groups (1.2 ± 1.1 versus 0.2 ± 0.5 days; p = 0.128). The patients with AAC and bacteremia were younger (53.8 ± 19.2 versus 60.2 ± 8 years; p = 0.021) and had a longer ICU length of stay (LOS) (12.6 ± 7.2 versus 1.3 ± 2.1 days; p = 0.030). However, there was no difference in the mortality rate in the groups (n = 2; 33.3% versus 1; 20.0%; p = 1.000). After adjusting for age, gender, BMI, and Charlson Comorbidity Index, bacteremia in AAC patients was found to be an independent variable for longer ICU LOS (odds ratio 8.8; 95% confidence interval 1.7-15.9; p = 0.024). Conclusions: The incidence of bacteremia in patients with AAC is five-fold higher and the ICU stay eight days longer than in patients with ACC.

Acalculous cholecystitis with gallbladder necrosis in a patient presenting without abdominal pain.

An 83-year-old man with a history of chronic myelogenous leukaemia in remission maintained with bosutinib presented with new-onset fevers. He denied pain and had no other focal symptoms. Ultrasound imaging revealed mild gallbladder wall thickening. Non-contrasted CT revealed right upper quadrant inflammation of indeterminate source. The diagnosis of acalculous cholecystitis was made on the third day when a CT with oral contrast demonstrated a remarkably inflamed biliary tree. The gallbladder was surgically removed and found to be necrotic. The case highlights an unusual presentation for a well-known condition. Both ultrasound and CT have limited diagnostic sensitivity for acalculous cystitis. This case adds to existing literature to support development of acalculous cholecystitis in non-critically ill patients. Clinicians should maintain awareness of this condition among patients presenting to the hospital or clinic with abdominal pain. Careful discussion with radiology and surgery is indicated to guide diagnostic testing when initial imaging results are indeterminate.

All the World Is a Nail: Why Are Surgeons Resistant to Learn How to Place Cholecystostomy Drains in Seriously Ill Patients With Acute Acalculous Cholecystitis?

Surgeons routinely provide palliative care, but often the technical procedure needed for the palliative intervention is beyond our training and comfort zone. This case is an example of surgical palliative care that utilizes image-guided techniques to provide optimal care. A frail elderly patient with multiple comorbidities who had been hospitalized for other diseases was diagnosed with acute acalculous cholecystitis. General surgery and gastroenterology were initially consulted, and the patient was referred to interventional radiology for a percutaneous cholecystostomy. The procedure was technically successful, and the patient's clinical status improved. A few days later, a follow-up cholecystogram showed a decompressed gallbladder, patent cystic duct, a common bile duct free of stones, and dilute contrast in the duodenum. After 2 weeks, the fistula tract was interrogated and found to be intact. The cholecystostomy tube was removed without incident. This case is presented as a call to action for surgeons to learn the skills required to place percutaneous cholecystostomies themselves and to add it to their surgical armamentarium.

Severe Persistent Hyponatremia: A Rare Presentation of Biliary Fluid Loss.

Hypotonic hyponatremia is caused by a serum sodium level of <135 mEq/L in the setting of excess solute loss accompanied by free water retention because of antidiuretic hormone release, subsequent to decreased effective arterial blood volume. Acute hyponatremia can have various neurological manifestations, including drowsiness, lethargy, coma, seizures, respiratory depression, and even death. In this article, we present a case of a 41-year-old man who presented with hyponatremia as a result of sodium containing biliary fluid loss and resultant renal free water retention in response to increased antidiuretic hormone secretion. He underwent placement of a cholecystostomy tube for acalculous cholecystitis and was found to be persistently hyponatremic despite repletion with sodium-containing fluids. Once the cholecystostomy tube was removed, the patient's sodium levels improved, and his symptoms resolved. Our case highlights choleuresis as an unusual but significant cause of hyponatremia in patients who have external biliary drainage.

Predicting factors for the diagnosis of gangrene acute cholecystitis.

Background: Gangrenous cholecystitis (GC) must be promptly treated for its high morbimortality. The object of our study is to identify clinical, laboratory or ultrasound factors that might us diagnose GC. Method: A Retrospective cohort study is devised including all patients admitted to Hospital de Laredo (Cantabria, Spain) between 2015 and 2017 with the diagnose of acute cholecystitis and having been operated. Patients were classified in two groups according to pathology: GC and non-GC. We compared their demographics characteristics, comorbidities, laboratory parameters and ultrasound findings. Results: A total of 115 patients were operated, of whom 32 had CG and 83 CNG. Neutrophil-to-lymphocyte ratio and C-reactive protein (CRP) showed significantly increased levels in GC group (p = 0.042) and CRP (p < 0.0001). To CRP showed an area under the ROC curve of 0.872 (95% confidence interval: 0.797-0.946). Acalculous cholecystitis was significantly associated to GC (24.1 vs. 7%; p < 0.005). In the multivariate analysis only the CPR showed as a predictive factor. A cutting point of CRP at 15.25 mg/dl, that had high sensibility (90.6%) and high negative predictive value (95%). Conclusion: CRP helped identify patients with CG to indicate early surgical intervention.

Antecedentes: La colecistitis aguda gangrenosa (CG) debe tratarse precozmente por su alto riesgo de morbimortalidad. Objetivo: Identificar factores clínicos, analíticos o ecográficos que permitan diagnosticar CG preoperatoriamente. Método: Estudio de cohorte retrospectiva en el Hospital de Laredo (Cantabria, España), entre 2015 y 2017, de pacientes con diagnóstico de colecistitis aguda que hayan sido intervenidos. Se clasificó a los pacientes en dos grupos según el diagnóstico anatomopatológico: CG y colecistitis no gangrenosa (CNG). Se compararon las características demográficas, la comorbilidad, los datos analíticos y los datos ecográficos. Resultados: Fueron operados 115 pacientes, de los cuales 32 tenían CG y 83 tenían CNG. Los pacientes con CG muestran unos valores más altos de índice de neutrófilos/linfocitos (p = 0.042) y de proteína C reactiva (PCR) (p < 0.0001). La colecistitis alitiásica se asoció con mas frecuencia a la CG (24.1 vs. 7.0%; p < 0.005). En el estudio multivariable, solo la PCR se muestra significativa. La PCR mostró un área bajo la curva ROC de 0.872, (intervalo de confianza del 95%: 0.797-0.946). Un punto de corte de PCR de 15.25 mg/dl tuvo una alta sensibilidad (90.6%) y un alto valor predictivo negativo (95%). Conclusión: La PCR ayuda a identificar a los pacientes con CG para indicar una intervención quirúrgica precoz.

[Three patients with large area burns complicated by acute acalculous cholecystitis].

From April 2017 to April 2018, three male patients aged 46-71 years with large area burns were treated in our hospital. Acute acalculous cholecystitis (AAC) symptoms of the patients began to appear 15-81 days after injury. AAC was diagnosed 24-81 days after injury. Ultrasound-guided percutaneous transhepatic cholecystostomy was performed 26-82 days after injury. The symptoms subsided in 2 patients, and cholecystectomy was performed in 1 patient with gallbladder perforation 94 days after injury. The patients were cured and discharged 41-118 days after injury. No recurrence of cholecystitis occurred during 8-9 months of follow-up after discharge.

Acalculous acute cholecystitis during the course of an enteroviral infection.

Gallbladder diseases are uncommon in children. Acalculous acute cholecystitis, although rare, is the most frequent form of acute cholecystitis in childhood. In acalculous acute cholecystitis, clinical presentation and laboratory findings are unspecific, making the diagnosis challenging. Abdominal ultrasonography is the first-line exam. Most cases of paediatric acalculous acute cholecystitis have been described in critically ill patients, but can occur in previously healthy children, without underlying diseases or severe conditions. The authors present a clinical report of a child with acalculous acute cholecystitis and enteroviral infection. Diagnosis, treatment, clinical course and prognosis are described. Pathophysiology, aetiology, diagnosis and treatment of acalculous acute cholecystitis are also discussed.

Acute Acalculous Cholecystitis in Hospitalized Patients With Hematologic Malignancies and Prognostic Importance of Gallbladder Ultrasound Findings.

OBJECTIVES: Patients with hematologic malignancies, especially those with acute disease or those receiving intense chemotherapy, are known to develop acute acalculous cholecystitis (AAC). The aim of this study was to evaluate the diagnostic and prognostic value of the established ultrasound (US) diagnostic criteria for AAC in patients with acute hematologic malignancies who were clinically suspected to have AAC. METHODS: We retrospectively studied the US findings of the gallbladder in patients with hematologic malignancies and correlated these findings with the duration of clinical symptoms, complications, and gallbladder-specific mortality. The major criteria were a 3.5-mm or thicker wall, pericholecystic fluid, intramural gas, and a sloughed mucosal membrane. The minor criteria were echogenic bile and hydrops (gallbladder distension > 4 cm). Ultrasound findings were considered positive if they included 2 major criteria or 1 major and 2 minor criteria. RESULTS: Ninety-four (25.5%) of 368 patients with hematologic malignancies had clinical signs of AAC during their acute phase of illness or during intense chemotherapy. Forty-three (45.7%) of these 94 patients had AAC-positive test results based on US criteria. The mean duration of symptoms was significantly longer (7.8 days) in this group than among the patients with negative test results (3.9 days; P < .001). Patients with positive test results had a higher rate of complications or mortality (20.9%) than those with negative test results (0%; P < .001). CONCLUSIONS: Symptomatic patients who meet the US criteria for the diagnosis of AAC have a poor prognosis. Other patients require a close follow-up US examination within 1 week to detect early progression.
