METHODS: A retrospective analysis of all patients with liver abscess from 1995 to 2004 was performed. Abscess was diagnosed as amebic in 661 (68%) patients, pyogenic in 200 (21%), indeterminate in 73 (8%) and mixed in 32 (3%). Multiple logistic regression analysis was performed to determine predictive factors for aspiration of liver abscess. RESULTS: A total of 966 patients, 738 (76%) male, mean age 43 ± 17 years, were evaluated: 540 patients responded to medical therapy while adjunctive percutaneous aspiration was performed in 426 patients. Predictive factors for aspiration of liver abscess were: age ≥ 55 years, size of abscess ≥ 5 cm, involvement of both lobes of the liver and duration of symptoms ≥ 7 d. Hospital stay in the aspiration group was relatively longer than in the non aspiration group. Twelve patients died in the aspiration group and this mortality was not statistically significant when compared to the non aspiration group. CONCLUSION: Patients with advanced age, abscess size > 5 cm, both lobes of the liver involvement and duration of symptoms > 7 d were likely to undergo aspiration of the liver abscess, regardless of etiology.展开更多

Generally, it presents as an intra-parenchymal hematoma following rupture of the affected vessels. The risk of rupture is linked to the volume of the malformation, its cortical location and venous drainage. In literature, few cases of rupture have been reported in cases of meningitis, but none are associated with a brain abscess. Objective: To report a case of an intraparenchymal hemorrhage due to rupture of an arteriovenous malformation with an associated brain abscess. Observation: The authors report the case of a 2-year-old child, admitted for impaired state of consciousness associated with a right hemiparesis and seizures in a febrile context. Clinical evaluation revealed a Blantyre score of 3, fever at 40˚C, divergent strabismus of the right eye, a right pyramidal syndrome and meningeal irritative syndrome. Cerebral CT scan revealed a left fronto-parietal intra-parenchymal hematoma and a right occipital ring-enhanced lesion, suggesting a brain abscess. An MRI suggested a probable rupture of an arteriovenous malformation resulting in the intra-parenchymal hematoma. Management consisted of craniotomy to evacuate the intra-parenchymal hematoma, antibiotic therapy with vancomycin and ceftriaxone at meningeal doses. Histopathological analysis of the intraoperative sample revealed an arteriovenous malformation. The postoperative course was marked by regression of hyperthermia, persistence of spasticity, irritability and clonic movement of the right lower limb. These were managed with baclofen, phenobarbital, and ergotherapy. We observed a regression of spasticity and improved motor skills in the right limbs. At 6 months follow-up, child could interact with his social environment despite aphasia, regression of spasticity and right hemiparesis. Conclusion: Rupture of arteriovenous malformations can be enhanced by neuro-meningeal infections and particularly brain abscesses. Cerebrovascular complications of these conditions mostly have unfavorable outcomes and neurological sequelae.展开更多

文摘AIM: To determine the predictive factors for early aspiration in liver abscess. METHODS: A retrospective analysis of all patients with liver abscess from 1995 to 2004 was performed. Abscess was diagnosed as amebic in 661 (68%) patients, pyogenic in 200 (21%), indeterminate in 73 (8%) and mixed in 32 (3%). Multiple logistic regression analysis was performed to determine predictive factors for aspiration of liver abscess. RESULTS: A total of 966 patients, 738 (76%) male, mean age 43 ± 17 years, were evaluated: 540 patients responded to medical therapy while adjunctive percutaneous aspiration was performed in 426 patients. Predictive factors for aspiration of liver abscess were: age ≥ 55 years, size of abscess ≥ 5 cm, involvement of both lobes of the liver and duration of symptoms ≥ 7 d. Hospital stay in the aspiration group was relatively longer than in the non aspiration group. Twelve patients died in the aspiration group and this mortality was not statistically significant when compared to the non aspiration group. CONCLUSION: Patients with advanced age, abscess size > 5 cm, both lobes of the liver involvement and duration of symptoms > 7 d were likely to undergo aspiration of the liver abscess, regardless of etiology.
文摘In the realm of medical rarity,the convergence of infective endocarditis with the development of an aortic root abscess stands as a formidable challenge,often bearing a grim prognosis.Recognizing this perilous condition requires a vigilant eye.Embolic events stemming from infective endocarditis can precipitate acute coronary syndrome,adding another layer of complexity to diagnosis and treatment.
文摘This manuscript is based on a recent study by Pillay et al that was published in recently.Liver abscesses can be caused by rare potentially life-threatening infections of either bacterial or parasitic origin.The incidence rate in Europe is lower than in developing countries,but it is a major complication with high morbidity,particularly in immunocompromised patients.They are most frequently caused by Enterobacterales infections,but hypervirulent Klebsiella strains are an emerging problem in Western countries.Amoebiasis has been a public health problem in Europe,primarily imported from other endemic foci.At the same time,this infection is becoming an emerging disease,as the number of infected patients who have not traveled to endemic areas is rising.Treatment options for hydatid liver cyst include chemotherapy,open or laparoscopic surgery,percutaneous treatment(percutaneous aspiration,re-aspiration and injection and its modification)and“wait and watch”strategy.Most hydatid liver cyst patients in Pillay et al’s study received surgical treatment,but several studies have confirmed the safety and efficacy of percutaneous aspiration,re-aspiration and injection.
文摘Rationale:Abdominal pain is a common complaint with a broad differential diagnosis,including both intra-abdominal and abdominal wall pathologies.While visceral causes are frequently considered,abdominal wall conditions are often overlooked,leading to diagnostic delays.Among them,umbilical abscesses are rare but require distinction from urachal abscesses due to differences in management.Patient’s concern:A 46-year-old woman presented with a one-week history of periumbilical pain unresponsive to analgesics.Diagnosis:Physical examination revealed localized tenderness and a positive Carnett’s sign.Computed tomographic images identified an umbilical abscess without evidence of urachal remnants,ruling out a urachal abscess.Interventions:The patient underwent abscess drainage and received cefalexin(1500 mg/day)for 28 days.Outcomes:The abscess resolved completely without recurrence.Lessons:Umbilical abscesses are rare and may be mistaken for urachal abscesses.A thorough clinical evaluation,including Carnett’s sign and imaging studies,is crucial for accurate diagnosis.Prompt differentiation facilitates appropriate management and prevents unnecessary interventions.
文摘In its classic form,amebic liver abscess(ALA)is a mild disease,which responds dramatically to antibiotics and rarely requires drainage.However,the two other forms of the disease,i.e.,acute aggressive and chronic indolent usually require drainage.These forms of ALA are frequently reported in endemic areas.The acute aggressive disease is particularly associated with serious complications,such as ruptures,secondary infections,and biliary communications.Laboratory parameters are deranged,with signs of organ failure often present.This form of disease is also associated with a high mortality rate,and early drainage is often required to control the disease severity.In the chronic form,the disease is characterized by low-grade symptoms,mainly pain in the right upper quadrant.Ultrasound and computed tomography(CT)play an important role not only in the diagnosis but also in the assessment of disease severity and identification of the associated complications.Recently,it has been shown that CT imaging morphology can be classified into three patterns,which seem to correlate with the clinical subtypes.Each pattern depicts its own set of distinctive imaging features.In this review,we briefly outline the clinical and imaging features of the three distinct forms of ALA,and discuss the role of percutaneous drainage in the management of ALA.
文摘Introduction: Arteriovenous malformation is a rare pathology, often discovered accidentally in children. Generally, it presents as an intra-parenchymal hematoma following rupture of the affected vessels. The risk of rupture is linked to the volume of the malformation, its cortical location and venous drainage. In literature, few cases of rupture have been reported in cases of meningitis, but none are associated with a brain abscess. Objective: To report a case of an intraparenchymal hemorrhage due to rupture of an arteriovenous malformation with an associated brain abscess. Observation: The authors report the case of a 2-year-old child, admitted for impaired state of consciousness associated with a right hemiparesis and seizures in a febrile context. Clinical evaluation revealed a Blantyre score of 3, fever at 40˚C, divergent strabismus of the right eye, a right pyramidal syndrome and meningeal irritative syndrome. Cerebral CT scan revealed a left fronto-parietal intra-parenchymal hematoma and a right occipital ring-enhanced lesion, suggesting a brain abscess. An MRI suggested a probable rupture of an arteriovenous malformation resulting in the intra-parenchymal hematoma. Management consisted of craniotomy to evacuate the intra-parenchymal hematoma, antibiotic therapy with vancomycin and ceftriaxone at meningeal doses. Histopathological analysis of the intraoperative sample revealed an arteriovenous malformation. The postoperative course was marked by regression of hyperthermia, persistence of spasticity, irritability and clonic movement of the right lower limb. These were managed with baclofen, phenobarbital, and ergotherapy. We observed a regression of spasticity and improved motor skills in the right limbs. At 6 months follow-up, child could interact with his social environment despite aphasia, regression of spasticity and right hemiparesis. Conclusion: Rupture of arteriovenous malformations can be enhanced by neuro-meningeal infections and particularly brain abscesses. Cerebrovascular complications of these conditions mostly have unfavorable outcomes and neurological sequelae.
文摘BACKGROUND Renal cysts,especially the cortical type,are a prevalent renal pathology.Most cases are asymptomatic and detected incidentally during abdominal imaging examination for unrelated complaints.They are often benign,but they can rarely transform into cystic renal malignancies.When huge or complicated,especially with an abscess,it may become symptomatic from the renal capsular stretch or inflammation.The open surgical,endoscopic,laparoscopic,and robotic appro-aches are available for symptomatic renal cyst treatment.This paper aims to report our experience in the management of a case of a giant renal cyst abscess.CASE SUMMARY This is a 26-year-old housewife who was referred to the urology outpatient clinic with a history of left flank pain and swelling for 5 months,with the transabdo-minal ultrasound scan and computerized tomography scan findings of a huge left renal cortical cyst(Bosniak I).She had associated anorexia,weight loss,nausea,and intermittent fever,which on one occasion was severe and high-grade with chills and rigors.This warranted hospital admission,analgesic and antibiotic therapy.The physical examination was unremarkable at presentation except for a ballotable and mildly tender left lumbar cystic mass.Her vital signs were stable.There was leukocytosis with relative neutrophilia.Further review of the imaging films confirmed the diagnosis of a left giant renal cortical cyst abscess.She was counselled and had open surgical exploration,drainage of 300 mL of pus,cyst unroofing with marsupialization,and was discharged home on the 10th postoperative day.CONCLUSION Treatment of giant simple renal cortical cyst abscesses should be individualized depending on the pathology in question,the surgeon’s experience,patient preference and availability of facilities for endoscopic,laparoscopic or robotic modalities.Notwithstanding open surgical exploration,cyst unroofing and marsupialization are useful modalities in giant renal cortical cyst abscesses and are associated with patient satisfaction.

文摘BACKGROUND Abdominal cocoons(ACs)lack characteristic clinical manifestations and are main-ly intestinal obstructions that are difficult to distinguish from intestinal obstruc-tion caused by other causes,resulting in difficult preoperative diagnosis and misdiagnosis and mistreatment.There are no reports of enterostomy occlusion caused by ACs in the literature at home and abroad.CASE SUMMARY Here,we report a 16-year-old female patient with intestinal obstruction due to AC.She was treated with abdominal surgery three times.First,she underwent a laparotomy for peritonitis after trauma from a traffic accident.During the pro-cedure,pelvic empyema,severe intestinal adhesions,and damage to the serous layer of the rectum were found,but no significant intestinal rupture and perfo-ration were found.As a precaution,she underwent a prophylactic ileostomy after a flush in her abdomen.The second and third surgeries were for treatment of recurrent stoma obstruction.The patient’s condition was complicated for a long period,but after comprehensive treatment by our department,the patient was successfully discharged from the hospital and is currently recovering well.CONCLUSION Currently,abdominal contrast-enhanced computed tomography is the best imaging modality for pre-operative evaluation of AC,but most patients are diagnosed only after intrao-perative exploration.For the treatment of typical or severe ACs,the primary me-thod of removal and healing of ACs is complete removal of the abdominal fibrous membrane.Finding a breakthrough in the anatomy is the key to the success of the surgery.
文摘BACKGROUND Rectal foreign bodies,though uncommon,present diagnostic and therapeutic challenges,particularly when they result from accidental ingestion.The non-specific symptoms and the potential for serious complications necessitate a thorough and methodical approach to diagnosis and treatment.This case report aims to highlight the diagnostic complexities and management strategies involved in treating a patient with a rectal foreign body,focusing on the use of advanced imaging techniques and the importance of a multidisciplinary approach.CASE SUMMARY A 48-year-old male with a history of hypertension presented with a one-year history of post-defecation anorectal pain and mild post-defecation rectorrhagia.Initial evaluation revealed hemodynamic stability and a tender,non-mucosal lesion in the anterior left rectal region.Imaging studies,including colonoscopy,magnetic resonance imaging,and endosonography,identified an erythematous,exophytic lesion and a perirectal abscess containing a foreign body.Surgical inter-vention revealed necrotic tissue and purulent material,along with two solid foreign body fragments(bone or plant matter).Postoperative follow-up showed the patient in good condition,and pathology confirmed the fragments as mature bone.CONCLUSION This case underscores the diagnostic challenges posed by rectal foreign bodies with nonspecific symptoms and no clear history of ingestion.
文摘BACKGROUND Effective management of liver abscess depends on timely drainage,which is influenced by the liquefaction degree.Identifying predictive factors is crucial for guiding clinical decisions.AIM To investigate the predictive factors of liver abscess liquefaction and develop a predictive model to guide optimal timing of percutaneous drainage.METHODS This retrospective study included 110 patients with pyogenic liver abscesses who underwent percutaneous catheter drainage.Patients were divided into a poor liquefaction group(n=28)and a well liquefaction group(n=82)based on the ratio of postoperative 24-hour drainage volume to abscess volume,using a cutoff value of 0.3.Clinical characteristics,laboratory indicators,and computed tomography imaging features were compared.A predictive model was constructed using logistic regression and evaluated using receiver operating characteristic curves and five-fold cross-validation.RESULTS Independent predictive factors for good liquefaction included the absence of diabetes[odds ratio(OR)=0.339,P=0.044],absence of pneumonia(OR=0.218,P=0.013),left-lobe abscess location(OR=4.293,P=0.041),cystic features(OR=5.104,P=0.025),and elevated preoperative serum alanine aminotransferase(ALT)levels(OR=1.013,P=0.041).The logistic regression model based on these factors demonstrated an area under the curve of 0.814,with a sensitivity of 90.24%and specificity of 67.86%.Five-fold cross-validation yielded an average accuracy of 83.61%and a kappa coefficient of 0.5209.CONCLUSION Pneumonia,diabetes,abscess location,abscess composition,and preoperative serum ALT levels are significant predictors of liver abscess liquefaction.The model can guide clinical decision-making.
文摘BACKGROUND Pyogenic liver abscess(PLA)is a prevalent liver infection with gradual onset and severe symptoms,including fever,abdominal pain,jaundice,and vomiting.Complications like sepsis or toxic shock can also occur.AIM To investigate the clinical value of early ultrasound-guided percutaneous drainage(PCD)in PLA patients,specifically those with non-liquefied abscesses,and evaluate the feasibility of early intervention.METHODS This retrospective analysis included 143 patients with PLA who were admitted to the Department of General Surgery between January 2018 and March 2023.All patients underwent ultrasound-guided PCD.Based on the liquefaction status of the abscess,patients were divided into two groups:Liquefied group and nonliquefied group.Clinical outcomes,including puncture success rate,puncture duration,length of hospital stay,time to fever resolution,abscess shrinkage rate,and complication rates,were compared between the two groups.RESULTS The puncture success rate for all patients was 99.3%,with a postoperative complication rate of 5.59%,and no intraoperative deaths occurred.Compared to the liquefied group,the non-liquefied group had significantly shorter hospital stays(3.9±1.8 days vs 5.1±2.7 days),faster fever resolution(2.4±1.1 days vs 4.9±2.2 days),and quicker abscess shrinkage(>50%)(4.7±1.5 days vs 8.6±3.3 days)(P<0.05).There were no significant differences in puncture success rates or complication rates between the two groups.CONCLUSION Early ultrasound-guided PCD can be safely and effectively performed in PLA,even when the abscess is not fully liquefied or is non-liquefied,supporting the clinical feasibility of early intervention.
文摘BACKGROUND Gastritis cystica profunda(GCP)is a rare submucosal gastric lesion characterized by the extension of cystically dilated gastric mucosal glands into or below the muscularis mucosa,often due to various underlying causes.Typically,asymptomatic or associated with mild symptoms,GCP is most commonly discovered incidentally during surgery or endoscopy.To the best of our knowledge,this is the first documented case of GCP accompanied by acute inflammation and abscess formation.CASE SUMMARY A 37-year-old woman presented with upper abdominal pain.Laboratory tests showed elevated inflammatory markers and carbohydrate antigen 19-9 levels.Gastroscopy revealed a submucosal bulge.Based on enhanced computed tomography findings,an ectopic pancreas with cyst was suspected.Clinically,we decided to perform distal gastrectomy.Postoperative pathology confirmed that the patient had GCP complicated by acute inflammation and abscess formation.The patient had an uneventful postoperative recovery.CONCLUSION This case provides information on new complications of GCP and emphasizes the diagnostic value of enhanced computed tomography.
文摘AIM:To report the demographic and systemic characteristics of patients,clinical progression of endophthalmitis,and the efficacy of various treatment strategies,with a focus on identifying key factors for preserving vision in eyes with endogenous endophthalmitis due to Klebsiella pneumoniae(K.pneumoniae)liver abscess.METHODS:In this single-center,retrospective case series of 18 patients with endogenous endophthalmitis due to K.pneumoniae liver abscess were analyzed.Ophthalmologic features of endophthalmitis at early,intermediate and advanced stages were obtained from eyes with endophthalmitis of different severities.Prompt vitrectomy was considered primarily for all eyes except for very early endophthalmitis.Intravitreal injections of antibiotics were performed in eyes with endophthalmitis in the very early stages and in eyes where vitrectomy was not available,and additional control of infection was needed after vitrectomy.Evisceration was performed in eyes with corneoscleral perforation,advanced endophthalmitis,perforation with preseptal or orbital cellulitis,uncontrolled infection,or severe pain with no vision.RESULTS:Mean(±standard deviation)age of the 18 patients with endophthalmitis was 64.5±12.2(range:32-84)y,and 14 patients(77.8%)were males.Endophthalmitis tended to involve the retinal parenchyma first and then progressed into the vitreous cavity and anterior segments.However,it presented a tendency to cause massive subretinal abscesses even after vitrectomy with silicone oil tamponade.Very high intraocular pressure with new vessels on the iris(41.7%)were also commonly observed.Although all but three patients had systemic disease such as diabetes or hypertension,visual prognosis after treatment did not appear to depend significantly on underlying comorbidities.A final best-corrected visual acuity better than 20/60 was achieved only when lesions were detected very early,with relatively good initial visual acuity,likely reflecting lower bacterial inoculation in the eye.CONCLUSION:Detection of early endophthalmitis lesions appears to be the only way to preserve good vision in patients with K.pneumoniae liver abscesses.Therefore,proper guidelines for ophthalmologic screening remain to be established for subjects at a high risk of endophthalmitis.
文摘BACKGROUND An epidural abscess is a rare but serious medical condition where a pocket of pus forms in the epidural space—the area between the outer covering of the spinal cord(the dura mater)and the bones of the spine.It’s usually caused by a bacterial infection,most commonly Staphylococcus aureus.The infection can spread to this area from other parts of the body,through the bloodstream,or it may be intro-duced directly during spinal procedures like epidural injections or surgery.Symptoms often include severe back pain,fever,and neurological deficits like weakness or numbness,which can progress quickly if untreated.It's considered a medical emergency because if the abscess compresses the spinal cord,it can lead to permanent paralysis or even death.Treatment usually involves antibiotics and,in many cases,surgical drainage.CASE SUMMARY Spinal epidural abscess(SEA)represents a rare yet potentially severe infection affecting the epidural space.We present the following case of a 54-year-old Hispanic white male who initially presented to the emergency department with acute deteriorating symptoms of bilateral lower extremity weakness,which subsequently progressed to involve the upper extremities.However,further evaluation uncovered additional notable symptoms,including urinary inconti-nence and decreased appetite.Further investigation broadened the differential diagnosis,including meningitis,spinal cord compression,acute pyelonephritis,osteomyelitis,bacteremia,torticollis,and acutely progressive ascending bilateral lower extremity weakness,raising the concern for possible Guillain-Barre syndrome.Diagnostic imaging,including magnetic resonance imaging of the spine,confirmed the presence of C5-C6 osteomyelitis and a C6-C7 spinal epidural abscess with severe canal narrowing.The patient underwent an emergency evacuation of epidural abscess with a C6 corpectomy and C5-C7 cervical fusion,followed by an 8-week course of intravenous antibiotics.Cultures from the abscess and bone revealed Staphylococcal aureus.The patient was discharged after 54 days with significant improvement in power and function.CONCLUSION This case highlights the importance of maintaining a high index of suspicion for SEA in patients presenting with atypical symptoms,even in the setting of seemingly unrelated conditions.Early recognition and prompt intervention are crucial to prevent permanent neurological deficits and improve outcomes in patients with SEA.
文摘BACKGROUND Although laparoscopic gastrolithotomy had been widely used in clinical practice,uncommon postoperative complications still require vigilance by medical staff.CASE SUMMARY Here we report a 67-year-old man who suffered for 18 months and underwent surgery several times due to a rare and undetected complication of laparoscopic gastricolithotomy.He presented to multiple hospitals because of sustained left upper quadrant abdominal pain one month after laparoscopic gastricolithotomy due to a large gastric bezoar caused by unrestrained eating of black dates and was diagnosed with possible intercostal neuritis.Many painkillers were used to relieve his symptoms but the condition progressed.Seven months after surgery,he was hospitalized as skin ulceration occurred in the left upper abdominal wall and was subsequently diagnosed with a massive thoracoabdominal wall abscess.One year after surgery,irreversible costal destruction was demonstrated.Both lesions were finally proved to be secondary damage due to a rare chronic gastro-abdominal wall fistula related to laparoscopic gastricolithotomy and the diameter of the gastric fistula reached 2 centimeters(cm).The patient was ultimately cured but underwent multi-regional incisions and drainage of the abscess,drainage of the gastric fistula,partial gastrectomy and removal of damaged ribs,and was followed-up for more than 4 years without recurrence.It is well-known that gastric fistula usually has an acute onset and occurs early after surgery,while chronic gastro-abdominal wall fistula especially with secondary massive thoracoabdominal wall abscess and costal destruction has rarely been reported.CONCLUSION This may be the first reported case of a chronic thoracoabdominal abscess and costal destruction caused by an undetected chronic gastro-abdominal wall fistula.We believe that this is a novel type of gastric fistula and the diagnosis and treatment were challenging.

文摘[Objectives]To investigate the use of the classical Chinese medicine formula Sihu Powder modified decoction for postoperative fumigation and sitz bath in patients with perianal abscess,aiming to promote wound healing and reduce medical burden.[Methods]An observational cohort study was conducted,selecting 200 patients with perianal abscess who underwent surgery in Shenzhen Guangming District People's Hospital.They were randomly divided into a treatment group and an observation group,with 100 cases in each group.Both groups followed the same surgical and antibiotic treatment principles.Starting from the first postoperative day,the treatment group received fumigation and sitz bath with modified Sihu Powder for decoction twice daily;the observation group used Compound Huangbai Liquid for fumigation and sitz bath twice daily.Indicators including pain score,wound secretion score,wound granulation tissue growth score,multidrug-resistant bacterial infection clearance rate,antibiotic usage days,and wound healing rate were observed in both groups 7,14 and 21 d after operation.[Results]On postoperative day 7,the differences in postoperative pain score,wound secretions,and multidrug-resistant bacterial clearance rate between the treatment group and the observation group were statistically significant.On postoperative day 14,the differences between the two groups were significant in indicators including pain score,wound secretions,wound granulation tissue growth,multidrug-resistant bacterial clearance rate,and wound healing rate.On postoperative day 21,the difference in wound healing rate between the two groups was significant;furthermore,the antibiotic usage days in the treatment group were significantly fewer than those in the observation group.[Conclusions]Modified Sihu Powder for fumigation and washing can effectively alleviate postoperative pain in perianal abscess patients,inhibit the colonization and infection of multidrug-resistant bacteria at the wound site,accelerate wound healing,reduce antibiotic usage intensity and medical burden.It possesses advantages such as being economical,effective,safe,and easy to operate,making it worthy of clinical promotion.
文摘BACKGROUND In recent years,there has been a significant increase in pyogenic liver abscesses(PLAs)caused by multidrug-resistant(MDR)Gram-negative bacteria(GNB),pre-dominantly Klebsiella pneumoniae and Escherichia coli.AIM To clarify the clinical characteristics and risk factors associated with MDR-GNB-related PLAs,develop a predictive nomogram for personalized risk assessment,and enhance the timeliness of empirical antibiotic selection.METHODS Based on the antibiotic susceptibility profiles,enrolled patients were divided into two groups:A MDR group com-prising 105 individuals and a non-resistant group comprising 163 individuals.A systematic collection of demo-graphic characteristics,laboratory findings,and prognostic indicators was performed.A predictive nomogram was established using multivariate stepwise regression modeling.Model effectiveness was evaluated by examining its discriminative capability,calibration accuracy,and clinical utility through receiver operating characteristic curves with corresponding area under the curve values,calibration graphs,and decision curve analysis.Continuous data were analyzed using the independent-sample t-test if they met normality criteria;otherwise,the Wilcoxon rank-sum test was adopted.For categorical data,Fisher’s exact test was chosen when the expected count in any cell was below five;in all other instances,the χ^(2) test was applied.RESULTS This retrospective study analyzed clinical and laboratory data from 268 patients diagnosed with Gram-negative PLA at a major healthcare facility from January 2019 to February 2025.Among these,105 cases(39%)were asso-ciated with MDR-GNB,primarily Klebsiella pneumoniae(43%)and Escherichia coli(42%).Mixed infections were rare,accounting for only 3%of cases.Multivariate regression revealed five independent predictors of MDR-GNB liver abscesses:Age≥60 years,diabetes,presence of a malignant tumor,lower C-reactive protein levels,and prolonged prothrombin time.These variables were integrated into a nomogram to facilitate individualized risk assessment.CONCLUSION The results imply that being aged over 60,diabetes,malignant tumor,lower C-reactive protein levels,and higher prothrombin time levels can accurately forecast MDR-GNB infections in PLAs,highlighting the importance of early screening to enable more targeted antibiotic treatments.However,as this was a single-center study without external validation,the generalizability of our model remains limited.Future multicenter,multi-ethnic prospective studies are needed to validate and extend these findings.
文摘In this editorial,we comment on the article published by Qiu et al.Pyogenic liver abscess is a serious clinical condition requiring timely and effective intervention.Ultrasound(US)-guided techniques-whether needle aspiration(NA)or catheter drainage-are key minimally invasive treatments,especially in patients with multiple or deep-seated abscesses where conventional surgery is often impractical.The timing and choice of evacuation method significantly influence clinical outcomes.Although catheter drainage may be necessary for larger or refractory collections,NA represents a less invasive alternative that is often sufficient for smaller abscesses-particularly multiloculated ones-and can avoid multiple catheter placements.This consideration is especially important in the early phase of the disease,when the abscess collection is poorly demarcated from surrounding tissue and more prone to bleeding during or after intervention.Traditional practice delays intervention until liquefaction occurs;however,emerging evidence supports early US-guided evacuation-even in partially liquefied or non-liquefied abscesses-as both safe and effective.Early intervention,particularly via NA when feasible,is associated with faster symptom resolution,shorter hospitalization,and fewer complications.This editorial explores the role of US-guided interventions in pyogenic liver abscess mana-ement,emphasizing the importance of individualized,timely approaches that optimize disease outcomes while minimizing procedural risk.
文摘BACKGROUND Liver cirrhosis patients can develop various complications including bacteremia as the intestinal flora is heterologous.In those with low immunity,trauma,or following surgery,etc.,the body is susceptible to concurrent systemic or local infections.Under these circumstances,even minimally invasive treatment methods such as interventional therapy like transjugular intrahepatic portosystemic shunt(TIPS)for liver cirrhosis patients can also result in complications such as infections.CASE SUMMARY A male patient with decompensated cirrhosis experienced multiple episodes of gastrointestinal bleeding and hypersplenism.He was admitted to hospital due to voluntary remedial TIPS.The patient developed a numerous intrahepatic liver abscess postoperatively.Following initial conservative treatment with intravenous antibiotics and parenteral nutrition,three months after TIPS,the liver abscess had disappeared on imaging examination.At the 6-month postoperative follow-up,outpatient re-examination showed that the patient had recovered and the liver abscess had resolved.CONCLUSION Attention should be paid to decreased blood cell counts,especially low leukocyte levels in patients with liver cirrhosis as the presence of intestinal microbiota dysregulation and portal pyemia can result in liver abscess and sepsis during invasive diagnostic and therapeutic procedures like TIPS.The addition of probiotics might reduce the risk in such patients.
