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.

Correlation of Inpatients Suffering from Acute Acalculous Cholecystitis during ICU Treatment with Acute Physiology and Chronic Health Evaluation II Score, Duration of Ventilator Use, and Time on Total Parenteral Nutrition.

Objective: To explore the correlation of inpatients suffering from acute acalculous cholecystitis (AAC) during ICU treatment with Acute Physiology and Chronic Health Evaluation II (APACHE-II) score, duration of ventilator use, and time on total parenteral nutrition (TPN). Methods: From March 2016 to March 2022, the clinical data of 47 patients with AAC who received ICU treatment in our hospital were retrospectively reviewed, and these patients were included in the AAC group. Another 36 patients treated in the ICU in the same period with age and gender matching with those in the AAC group were selected as the non-AAC group. Patients' various clinical data were recorded to analyze the correlation of AAC with APACHE-II score, duration of ventilator use, and time on TPN. Results: The shock time, duration of ventilator usage, and duration of sedative medicine use were all substantially longer in the AAC group than in the non-AAC group, according to the univariate analysis (P < 0.05); the amount of norepinephrine used, white blood cell count, C-reactive protein (CRP) amount, and APACHE-II score were significantly higher in the AAC group than in the non-AAC group (P < 0.05); between the two groups, the time on TPN and fasting time were different, but with no statistical significance (P > 0.05); after performing Spearman's correlation with the significantly between-group different indicators, the result showed that the amount of norepinephrine used, duration of ventilator use, white blood cell count, and CRP amount were significantly correlated with the occurrence of AAC, and the correlation was positive (P all <0.001). Conclusion: The APACHE-II score and time on TPN are not significantly correlated with the occurrence of AAC; and the amount of norepinephrine used, duration of ventilator use, white blood cell count, and serum CRP are positively correlated with the occurrence of AAC. Measuring the variations in the levels of various markers can signal the onset of AAC or reflect the state and prognosis, suggesting a possible application in clinic-based targeted prevention and treatment of AAC.

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.

Long-term outcomes of acute acalculous cholecystitis treated by non-surgical management.

Although cholecystectomy is generally recommended for acute acalculous cholecystitis (AAC) treatment, non-surgical management can be considered in patients at a high risk for surgery. This study compared outcomes of surgical and non-surgical management and analyzed the long-term outcomes of AAC patients managed non-surgically.We retrospectively analyzed 89 patients diagnosed with AAC between January 1, 2007 and April 30, 2014. These patients were divided into 2 groups: non-surgical (n = 41) and surgical (n = 48). Non-surgical management methods were percutaneous cholecystostomy (PC, n = 14) and antibiotics only (n = 27). The non-surgical group was followed up for >3 years after treatment.The mean age was slightly higher in the non-surgical group than in the surgical group without significant difference. The prevalence of cerebrovascular accident in the non-surgical group was significantly higher than that in the surgical group (26.8% vs 8.3%, P = .020). Mean hospital stay was not statistically different between two groups. The surgical group had a significantly higher incidence of posttreatment complications than the non-surgical group (18.8% vs 2.4%, P = .015). During the mean follow-up of 5.7 years, AAC recurred in 4 (9.8%) patients in the non-surgical group. Three patients underwent cholecystectomy, 1 was treated with antibiotics, and no recurrence-related death occurred. The recurrence rate of AAC was not different between PC and antibiotics only groups (14.3% vs 7.4%, P = .596).Recurrence was observed in 9.8% of AAC patients treated non-surgically and the outcome in the non-surgical group was not inferior to that in the surgical group.

Percutaneous Cholecystolithotomy Using Cholecystoscopy.

The morbidity and mortality of cholecystectomy can increase to 10% in high surgical risk patients. The technique for percutaneous cholecystolithotomy consists of 3 steps: (1) percutaneous cholecystostomy, (2) tract dilation and cholecystolithotomy, and (3) tract evaluation and catheter removal. Cholecystoscopy is critical in guiding the lithotripsy probe for fragmentation of large stones and is useful for locating small stone fragments not seen in cholangiography. Cholecystoscopy is also useful for assessing ambiguous lesions and in distinguishing between stone vs debris or mass. Technical success rate of percutaneous cholecystolithotomy using cholecystoscopy ranges from 93% to 100%. Procedure related complication rate has been reported as 4%-15%. The most common complication is bile leak during the procedure or after catheter removal. Although recurrence rate of gallstones has been reported up to 40%, the symptom recurrence rate is much lower. Therefore, percutaneous cholecystolithotomy using cholecystoscopy can be an alternative to cholecystectomy in high surgical risk patients with symptomatic gallstones.

[Effects of magnetic laser therapy on the gastroduodenal system of patients with chronic acalculous cholecystitis]. / Vliianie magnitno-lazernoi terapii na sostoianie gastroduodenal'noi sistemy u bol'nykh khronicheskim nekal'kuleznym kholetsistitom.

BACKGROUND: The inflammatory process in the hepatobiliary system contributes to the development and progression of pathological changes in the adjacent digestive organs. The data available in the literature suggest that laser radiation and magnetic therapy are effective in treating hepatobiliary diseases. AIM: To evaluate the effects of magnetic laser radiation on the status of gastroduodenal organs in patients with chronic acalculous cholecystitis. SUBJECTS AND METHODS: Fifty patients with chronic acalculous cholecystitis, mostly women, were followed up; their mean age was 44±8 years (36 to 56 years); the disease duration was 6±1.5 years. The patients were randomized into 2 groups: 1) a comparison group (n=20) and 2) a study group (n=30). Both groups were homogeneous for sex, age, disease duration and severity. The basic treatment included the oral intake of Jermuk mineral water according to the generally accepted scheme, acupuncture, iodine-bromine baths, massage of the collar area, exercise therapy, and, if indicated, therapeutic enemas. During the basic treatment, the patients in the study group were prescribed magnetic laser radiation to the right subcostal area. Results were assessed at 20-22 days after treatment. RESULTS: The performed treatment resulted in positive clinical changes and improvement in the indicators characterizing the status of gastroduodenal organs. CONCLUSION: The studies have established that rehabilitation in patients with chronic acalculous cholecystitis along with laser radiation contributes to positive clinical changes and improvement in the status of the gastroduodenal system. There is a tendency to normalize acid-forming function and morphological state of the gastric and duodenal mucosa.

Acute calculous cholecystitis: a real-life management study in a tertiary teaching hospital.

AIM: to describe the management of acute calculous cholecystitis in a tertiary teaching hospital and the outcomes obtained. MATERIAL AND METHODS: a retrospective single tertiary center cohort study. RESULTS: medical records of 487 patients were analyzed. The mean follow-up was 44.5 ± 17.0 months. Treatment alternatives were cholecystectomy (64.3%), conservative treatment (23.0%), endoscopic retrograde cholangiopancreatography (17.4%), percutaneous cholecystostomy (10.7%) and endoscopic ultrasound-guided gallbladder drainage (0.8%). Most cholecystectomies were delayed (88.8%). Recurrences occurred in 38.2% of patients. Although cholecystectomy was the therapeutic approach with the lowest recurrence rate once performed, 44.6% of patients that underwent delayed surgery had pre-surgical recurrences. CONCLUSIONS: delayed cholecystectomy is still commonly performed, even though it is related with a high frequency of preoperative recurrences.

Infectious mononucleosis - not always a benign condition: a case report of infectious mononucleosis-associated acute acalculous cholecystitis.

Infectious mononucleosis is typically a self-limited viral infection of adolescence and early adulthood that resolves in a period of weeks, causing no major sequelae. We describe a case of a healthy 18-year-old female diagnosed with infectious mononucleosis who also presented with right upper quadrant abdominal pain, moderate transaminitis, and cholestatic biochemistry. An ultrasound revealed acute acalculous cholecystitis, generally a condition seen in the context of critical illness. Further investigating emergency department patients with infectious mononucleosis is often not indicated, but may be important for those who present atypically.

Acute acalculous cholecystitis in children.

Acute acalculous cholecystitis (AAC) is the inflammatory disease of the gallbladder in the absence of gallstones. AAC is estimated to represent at least 50% to 70% of all cases of acute cholecystitis during childhood. Although this pathology was originally described in critically ill or post-surgical patients, most pediatric cases have been observed during several infectious diseases. In addition to cases caused by bacterial and parasitic infections, most pediatric reports after 2000 described children developing AAC during viral illnesses (such as Epstein-Barr virus and hepatitis A virus infections). Moreover, some pediatric cases have been associated with several underlying chronic diseases and, in particular, with immune-mediated disorders. Here, we review the epidemiological aspects of pediatric AAC, and we discuss etiology, pathophysiology and clinical management, according to the cases reported in the medical literature.

Recent advances in management of acalculous cholecystitis.

Acalculous cholecystitis is a life-threatening gallbladder infection that typically affects the critically ill. A late diagnosis can have devastating outcomes because of the high risk of gallbladder perforation if untreated. The diagnosis is not straightforward as Murphy's sign is difficult to illicit in the critically ill and many imaging findings are either insensitive or non-specific. This article reviews the current imaging literature to improve the interpretation of findings. Management involves a percutaneous cholecystostomy, surgical cholecystectomy, or more recently an endoscopically placed metal stent through the gastrointestinal tract into the gallbladder. This article reviews the current literature assessing the outcomes of each treatment option and suggests a protocol in determining the modality of choice on the basis of patient population. Specifically, endoscopic ultrasound-guided gallbladder drainage is a novel drainage approach for patients who are poor candidates for surgery and obviates the need for a percutaneous drain and all its complications. It has promising results but has caveats in its uses.

Acute Acalculous Cholecystitis in Burns: A Review.

Acute acalculous cholecystitis (AAC) is an acute inflammatory disorder of the gallbladder, which can complicate the recovery of burn patients. No formal literature review has been performed about this uncommon but potentially fatal complication in burn care. A Pubmed search from 1950 to 2015 was performed using MESH terms: "acalculous cholecystitis," "burns or thermal injuries or thermal damage," and "cholecystitis or gallbladder inflammation." The articles were analyzed and data collected individually on the incidence, presenting symptoms or signs, risk factors, investigations, and treatment modalities used. An International Burns Injury Database (IBID) search was additionally performed to identify the incidence of AAC in burn patients between 2005 and 2015 in the United Kingdom. Nineteen articles were identified which described 90 cases of AAC and thermal injuries. The incidence of AAC in burns ranges between 0.4 and 3.5%, typically affecting males (82.4%) with a mean age of 35 (range 13-89), and 97.8% of burns were >30% total body surface area (range: 22-80%). The majority of patients had established known risk factors for acquiring AAC, including blood transfusion (56.6% of patients), sepsis (52.2%), mechanical ventilation (45.5%), prolonged fasting or total parenteral nutrition administration (44.4%), and use of narcotic medication (10%). The IBID search identified one case of AAC among 145,227 burn injuries during 2005 to 2015 in the United Kingdom. AAC is a rare life-threatening condition that is associated with large thermal burns. Improvements in burns critical care have probably improved the management of known risk factors and reduced the incidence of this condition over recent decades.

Expanding role of percutaneous cholecystostomy and interventional radiology for the management of acute cholecystitis: An analysis of 144 patients.

PURPOSE: To investigate the rates of interval cholecystectomy and recurrent cholecystitis after initial percutaneous cholecystostomy (PC) and identify predictors of patient outcome after PC. MATERIALS AND METHODS: A total of 144 patients with acute cholecystitis who were treated with PC were included. There were 96 men and 48 women, with a mean age of 71±13 (SD) years (range: 25-100 years). Patient characteristics, diagnostic imaging studies and results of laboratory tests at initial presentation, clinical outcomes after the initial PC treatment were reviewed. RESULTS: Among the 144 patients, 56 patients were referred for acute acalculous and 88 patients for calculus cholecystitis. Five procedure-related major complications (3.6%) were observed including bile peritonitis (n=3), hematoma (n=1) and abscess formation (n=1). Recurrent acute cholecystitis after initial clinical resolution and PC tube removal was observed in 8 patients (6.0%). The rate of interval cholecystectomy was 33.6% (47/140) with an average interval period of 100±482 (SD) days (range: 3-1017 days). PC was a definitive treatment in 85 patients (60.7%) whereas 39 patients (27.9%) had elective interval cholecystectomy without having recurrent cholecystitis. The clinical outcomes after PC did not significantly differ between patients with calculous cholecystitis and those with acalculous cholecystitis. Multiple prior abdominal operations were associated with higher rates of recurrent cholecystitis. CONCLUSION: For both acute acalculous and calculous cholecystitis, PC is an effective and definitive treatment modality for more than two thirds of our study patients over 3.5-year study period with low rates of recurrent disease and interval cholecystectomy.

Neutropenic acute acalculous cholecystitis (AAC) in a 12-year-old boy with T-acute lymphoblastic leukemia successfully managed with conservative treatment.

Acute acalculous cholecystitis (AAC) is an inflammation of the gallbladder without the presence of gallstones. In children with malignancies or chemotherapy-induced neutropenia, AAC is very rare. Clinical diagnosis of AAC remains difficult in this patient population but an early recognition followed by an appropriate intervention may confer a benefit. Only three pediatric patients with underlying hematological malignancies whose clinical treatment course was complicated by the development of AAC have been described. We describe a neutropenic pediatric patient who developed AAC following chemotherapy for acute T-cell acute lymphoblastic leukemia (T-ALL), which was successfully managed with conservative treatment. ABBREVIATIONS: AAC: Acute acalculous cholecystitis; T-ALL: T-cell acute lymphoblastic leukemia; TPN: Total parenteral nutrition.

So-called Acute Acalculous Cholecystitis in Macrophage Activation Syndrome.

Acute acalculous cholecystitis (AAC) is a severe disease seen in critically ill patients, including those with autoimmune diseases. We herein report the case of a 41-year-old female who developed macrophage activation syndrome (MAS) accompanied by a recurrence of Kikuchi disease. Abdominal imaging revealed marked thickening of the gallbladder wall and pericholecystic fluid, typically found in AAC. Treatment with intravenous pulse methylprednisolone induced in a significant improvement in the gallbladder wall, resulting in no need for surgical intervention. We should consider that patients with MAS may therefore sometimes develop AAC and that early immunosuppressive therapy can be effective in AAC cases associated with rheumatic or autoimmune diseases.

An unusual etiology of abdominal pain in children.

The first case of cholecystitis acalculous by Cryptosporidium in onco-hematology pediatric patient was described in this work.

Endoscopic Transpapillary Gallbladder Stent Placement Is Safe and Effective in High-Risk Patients Without Cirrhosis.

BACKGROUND: Endoscopic transpapillary gallbladder stent (ETGS) placement is a proposed minimally invasive alternative to cholecystectomy in high-risk patients with symptomatic gallbladder disease. AIMS: To describe the safety and efficacy of ETGS placement in 29 consecutive patients without cirrhosis. METHODS: A retrospective analysis of consecutive ETGS cases from 2005 to 2013 at a referral center was undertaken. RESULTS: The mean age was 70 years (range 40-91), and 62 % were hospitalized. The most common indication for ETGS was acute calculus cholecystitis (52 %). Comorbidities precluding cholecystectomy included advanced cancer (45 %), severe cardiopulmonary disease (21 %), and advanced age/frailty (17 %). Eighty-six percent of the patients had an ASA class of III or IV, and the Charlson comorbidity index was >3 in 55 %. An ETGS was successfully placed in 22 patients (76 %) with 18 being successful on the first attempt. A percutaneous rendezvous approach was required to obtain cystic duct access in six patients (21 %). During a mean follow-up of 376 days, a sustained clinical response was noted in 90 % of the patients with a stent placed. No peri-procedural complications were noted. However, two patients developed delayed complications of abdominal pain and cholangitis. Six patients were alive with their original stent still in place at a mean follow-up of 2.5 years. CONCLUSIONS: ETGS is an effective and safe alternative to cholecystectomy in high-risk patients. Technical success can be facilitated by a percutaneous rendezvous technique. Our data and those of others suggest that scheduled stent exchanges may not be required unless a clinical change occurs.

Risk factors and therapeutic outcomes of acute acalculous cholecystitis.

OBJECTIVE: Acute acalculous cholecystitis (AAC) is traditionally known to occur in critically ill patients and to have a poor prognosis. Although cholecystectomy is usually recommended for treating AAC, nonsurgical management may be a good alternative. The objective of this study was to review the incidence, risk factors, treatment modality, and therapeutic outcomes of AAC compared to acute calculous cholecystitis (ACC). MATERIAL AND METHODS: Data from 69 patients with AAC and 415 patients with ACC between January 2007 and August 2011 were collected. Analysis and comparison of clinicopathological features and therapeutic outcomes between patients with AAC and those with ACC was performed. RESULTS: The number of patients over 50 years of age was significantly higher in the AAC group compared with the ACC group (92.8 vs. 81.7%, p = 0.023). Cerebrovascular accidents were significantly more frequent in patients with AAC than in those with ACC (15.9 vs. 6.7%, p = 0.016). A higher incidence of gangrenous cholecystitis was observed in the AAC group (31.2 vs. 5.6%, p = 0.001). The overall therapeutic outcomes for patients did not differ statistically between the AAC and ACC groups, irrespective of treatment modalities. The recurrence rate after nonsurgical treatment was significantly lower in the AAC group than in the ACC group (2.7 vs. 23.2%, p = 0.005). CONCLUSIONS: The risk of AAC increases in patients with advanced age and cerebrovascular accidents. Incidence of gangrenous cholecystitis was higher in AAC compared to ACC. Nonsurgical treatments such as antibiotics alone or percutaneous cholecystostomy might be effective in selected patients.
