[Infectious mononucleosis : an atypical cause of acute alithiasic cholecystitis]. / La mononucléose infectieuse : une cause atypique de cholécystite aiguë alithiasique.

The Epstein-Barr virus (also known as EBV), responsible for infectious mononucleosis, is a virus that infects the majority of the world's population. Infection occurs in several forms, most often asymptomatic, or as a fever accompanied by pharyngitis and lymphadenopathies. A rare complication of infectious mononucleosis is acute acalculous cholecystitis, an inflammation of the gallbladder characterized by ischaemia and severe cholestasis. The diagnosis of this pathology is made by imaging, but determining the cause may be tricky. We present here the case of acute acalculous cholecystitis in a 21-year-old woman. This case highlights a rare complication of EBV infection that is probably under-diagnosed, and demonstrates the usefulness of interpreting liver tests and leukocyte count in association with imaging findings.

Le virus d'Epstein-Barr (aussi appelé EBV), responsable de la mononucléose infectieuse, est un virus qui infecte la majorité de la population mondiale. L'infection se présente sous plusieurs formes, soit, le plus souvent, asymptomatique, soit avec une fièvre accompagnée d'une pharyngite et de lymphadénopathies. Une des rares complications de la mononucléose infectieuse est la cholécystite aiguë alithiasique, une inflammation de la vésicule biliaire, caractérisée par une ischémie et une cholestase importante. Le diagnostic de cette pathologie est réalisé par imagerie et la détermination de la cause peut s'avérer compliquée. Nous présentons ici le cas clinique d'une cholécystite aiguë alithiasique chez une jeune femme de 21 ans. Ce cas nous permet de mettre en lumière une complication rare de l'infection par l'EBV, probablement sous-diagnostiquée, et démontre l'utilité d'interpréter les tests hépatiques ainsi que la formule leucocytaire en relation avec les résultats d'une imagerie.

Portal vein thrombosis associated with acute cholecystitis.

ABSTRACT: Portal venous thrombosis (PVT) is an uncommon clinical problem and is rare following cholecystectomy. This article describes a patient who developed PVT after an initially uneventful laparoscopic cholecystectomy. The patient was successfully treated with IV antibiotics and anticoagulation.

Application of 3-Step Laparoscopic Cholecystectomy in Acute Difficult Cholecystitis.

BACKGROUND: With the aging of the global population, the incidence rate of acute cholecystitis is increasing. Laparoscopic cholecystectomy is considered as the first choice to treat acute cholecystitis. How to effectively avoid serious intraoperative complications such as bile duct and blood vessel injury is still a difficult problem that puzzles surgeons. This paper introduces the application of laparoscopic cholecystectomy, a new surgical concept, in acute difficult cholecystitis. METHODS: This retrospective analysis was carried out from January 2019 to January 2021. A total of 36 patients with acute difficult cholecystitis underwent 3-step laparoscopic cholecystectomy. The general information, clinical features, surgical methods, surgical results, and postoperative complications of the patients were analyzed. RESULTS: All patients successfully completed the surgery, one of them was converted to laparotomy, and the other 35 cases were treated with 3-step laparoscopic cholecystectomy. Postoperative bile leakage occurred in 2 cases (5.56%), secondary choledocholithiasis in 1 case (2.78%), and hepatic effusion in 1 case (2.78%). No postoperative bleeding, septal infection, and other complications occurred, and no postoperative colon injury, gastroduodenal injury, liver injury, bile duct injury, vascular injury, and other surgery-related complications occurred. All 36 patients were discharged from hospital after successful recovery. No one died 30 days after surgery, and there was no abnormality in outpatient follow-up for 3 months after surgery. CONCLUSIONS: Three-step laparoscopic cholecystectomy seems to be safer and more feasible for acute difficult cholecystitis patients. Compared with traditional laparoscopic cholecystectomy or partial cholecystectomy, 3-step laparoscopic cholecystectomy has the advantages of safe surgery and less complications, which is worth trying by clinicians.

Acute cholecystitis, obesity, and steatohepatitis constitute the lethal triad for bile duct injury (BDI) during laparoscopic cholecystectomy.

OBJECTIVE: The most feared complication during laparoscopic cholecystectomy remains a bile duct injury (BDI). Accurately risk-stratifying patients for a BDI remains difficult and imprecise. This study evaluated if the lethal triad of acute cholecystitis, obesity, and steatohepatitis is a prognostic measure for BDI. METHODS: A retrospective review of the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) registry was performed. All laparoscopic cholecystectomy cases within the main NSQIP database for 2012-2019 were queried. Two study cohorts were constructed. One with the lethal triad of acute cholecystitis, BMI ≥ 30, and steatohepatitis. The other cohort did not have the full triad present. Multivariate analysis was performed via logistic regression modeling with calculation of odds ratios (OR) to identify independent factors for BDI. An uncontrolled and controlled propensity score match analysis was performed. RESULTS: A total of 387,501 cases were analyzed. 36,887 cases contained the lethal triad, the remaining 350,614 cases did not have the full triad. 860 BDIs were identified resulting in an overall incidence rate 0.22%. There were 541 BDIs within the lethal triad group with 319 BDIs in the other cohort and an incidence rate of 1.49% vs 0.09% (P < 0.001). Multivariate analysis identified the lethal triad as an independent risk factor for a BDI by over 15-fold (OR 16.35, 95%CI 14.28-18.78, P < 0.0001) on the uncontrolled analysis. For the controlled propensity score match there were 29,803 equivalent pairs identified between the cohorts. The BDI incidence rate remained significantly higher with lethal triad cases at 1.65% vs 0.04% (P < 0.001). The lethal triad was an even more significant independent risk factor for BDI on the controlled analysis (OR 40.13, 95%CI 7.05-356.59, P < 0.0001). CONCLUSIONS: The lethal triad of acute cholecystitis, obesity, and steatohepatitis significantly increases the risk of a BDI. This prognostic measure can help better counsel patients and potentially alter management.

A Review on Endoscopic Management of Acute Cholecystitis: Endoscopic Ultrasound-Guided Gallbladder Drainage and Endoscopic Transpapillary Gallbladder Drainage.

A percutaneous cholecystostomy tube (PCT) is the conventionally favored nonoperative intervention for treating acute cholecystitis. However, PCT is beset by high adverse event rates, need for scheduled reintervention, and inadvertent dislodgement, as well as patient dissatisfaction with a percutaneous drain. Recent advances in endoscopic therapy involve the implementation of endoscopic transpapillary drainage (ETP-GBD) and endoscopic ultrasound-guided gallbladder drainage (EUS-GBD), which are increasingly preferred over PCT due to their favorable technical and clinical success combined with lower complication rates. In this article, we provide a comprehensive review of the literature on EUS-GBD and ETP-GBD, delineating instances when clinicians should opt for endoscopic management and highlighting potential risks associated with each approach.

Acute cholecystitis: how to avoid subtotal cholecystectomy-preliminary results.

BACKGROUND: The aim of this manuscript is to illustrate a new method permitting safe cholecystectomy in terms of complications with respect to the common bile duct (CBD). METHODS: The core of this new technique is identification of the continuity of the cystic duct with the infundibulum. The cystic duct can be identified between the inner gallbladder wall and inflamed outer wall. RESULTS: In the last 2 years, from January 2019 until December 2021, 3 patients have been treated with the reported technique without complications. CONCLUSIONS: Among the various cholecystectomy procedures, this is a new approach that ensures the safety of the structures of Calot's triangle while providing the advantages gained from total removal of the gallbladder.

Safety and adverse events of EUS-guided gallbladder drainage using lumen-apposing metal stents and percutaneous cholecystostomy tubes: a systematic review and meta-analysis.

BACKGROUND AND AIMS: EUS-guided gallbladder drainage using lumen-apposing metal stents (EUS-GBD-LAMSs) and percutaneous cholecystostomy for gallbladder drainage (PTGBD) are the alternative treatment modalities in high-risk surgical patients with acute cholecystitis (AC). The aim of this study was to compare the safety of these procedures for AC in surgically suboptimal candidates. METHODS: Six studies compared the 2 groups' early, delayed, and overall adverse events; they also compared length of hospital stay, re-interventions, and re-admissions rate. A random effect model calculated odds ratios (ORs) with a 95% confidence interval (CI). RESULTS: The 2 groups had similar early adverse events; however, EUS-GBD-LAMS was associated with a lower rate of delayed (OR, .21; 95% CI, .07-.61; P ≤ .01) and overall (OR, .43; 95% CI, .30-.61; P ≤ .01) adverse events. Patients with EUS-GBD-LAMSs had a shorter hospital stay than PTGBD. CONCLUSIONS: EUS-GBD-LAMS is a safer option than PTGBD and is associated with a shorter hospital stay in nonsurgical candidates with AC.

Endoscopic Gallbladder Drainage Conversion versus Conservative Treatment Following Percutaneous Gallbladder Drainage in High-Risk Surgical Patients.

Background/Aims: There are no consensus guidelines for patients with acute cholecystitis undergoing percutaneous cholecystostomy who are unfit for interval cholecystectomy. The current study aimed to compare the clinical outcomes of endoscopic gallbladder drainage, i.e. conversion from percutaneous cholecystostomy (including endoscopic transpapillary gallbladder stenting and endoscopic ultrasound-guided gallbladder drainage), and conservative treatment after percutaneous cholecystostomy tube removal. Methods: This retrospective review included patients who underwent percutaneous cholecystostomy for acute cholecystitis between January 2017 and December 2020. Consecutive patients who underwent endoscopic gallbladder drainage or percutaneous cholecystostomy tube removal without interval cholecystectomy were included. Outcome measures included recurrent acute cholecystitis and unplanned readmission due to gallstone-related diseases. Results: During the study period, 238 patients were selected (63 underwent endoscopic gallbladder drainage conversion and 175 underwent conservative treatment). Patients who underwent endoscopic gallbladder drainage conversion had lower rates of recurrent acute cholecystitis (3 [4.76%] vs 31 [17.71%], p=0.012) and unplanned readmission due to gallstone-related diseases (6 [9.52%] vs 40 [22.86%], p=0.022) than those who underwent conservative treatment following percutaneous cholecystostomy tube removal. In the univariate and multivariate analyses, calculus cholecystitis (odds ratio, 13.75; 95% confidence interval, 1.83 to 102.83; p=0.011) and conversion of endoscopic gallbladder drainage (odds ratio, 0.23; 95% confidence interval, 0.06 to 0.78; p=0.019) were significant predictive factors for recurrent acute cholecystitis. Conclusions: Endoscopic gallbladder drainage conversion led to more favorable outcomes than conservative treatment after percutaneous cholecystostomy tube removal. Therefore, endoscopic gallbladder drainage conversion may be considered a promising treatment option for patients undergoing percutaneous cholecystostomy who are at a high surgical risk.

Evaluating Clinical Outcomes of Laparoscopic Subtotal and Total Cholecystectomy for Complicated Acute Cholecystitis: A Systematic Review and Meta-Analysis.

INTRODUCTION: This systematic review and meta-analysis aimed to compare clinical outcomes in patients with complicated acute cholecystitis undergoing laparoscopic total vs subtotal cholecystectomy. METHODS: This systematic review and meta-analysis was conducted according to PRISMA guidelines and queried PubMed, Embase, ProQuest, Google Scholar, and Cochrane databases from inception to May 2023. The primary outcome was complication rates including common bile duct injury, wound infection, reoperation, bile leak, retained stones, and subhepatic collection, whereas secondary outcomes were in-hospital mortality and hospital length of stay. RESULTS: A total of 7 studies with 135,233 cases were included for meta-analysis. Patients who underwent laparoscopic total cholecystectomy had a significantly lower risk of postoperative bile leaks (RR: .15; 95% CI: .03, .80) and subhepatic fluid collection (RR: 0.19; 95% CI: .06, .63) and were 2.94 times less likely to die compared to those who underwent subtotal cholecystectomy (RR .34; 95% CI: .15, .77). Patients who underwent subtotal cholecystectomy had significantly longer hospital length of stay (mean difference 1.0 days; 95% CI: .5 days, 1.4 days). CONCLUSIONS: In adult patients presenting with complicated cholecystitis, management with laparoscopic subtotal cholecystectomy presents a unique complication profile with increased risk of postoperative bile leak and subhepatic fluid collection, in-hospital mortality, and longer hospital length-of-stay when used as an alternative approach to laparoscopic total cholecystectomy. Further research into the most appropriate clinical scenarios and patient populations for the use of the subtotal cholecystectomy approach may prove useful in improving its associated outcomes.

Influence of Percutaneous Transhepatic Gallbladder Aspiration and Drainage for Severe Acute Cholecystitis on the Surgical Outcomes of Subsequent Laparoscopic Cholecystectomy: Post Hoc Analysis of the CSGO-HBP-017 (CSGO-HBP-017C).

OBJECTIVE: Percutaneous transhepatic gallbladder aspiration (PTGBA) and/or drainage (PTGBD) are useful approaches in the management of acute cholecystitis in patients who cannot tolerate surgery because of poor general condition or severe inflammation. However, reports regarding its effect on the surgical outcomes of subsequent laparoscopic cholecystectomy (LC) are sparse. The aim of this retrospective study was to investigate the influence of PTGBA on surgical outcomes of subsequent LC by comparing the only-PTGBA group, including patients who did not need the additional-PTGBD, versus the additional-PTGBD group, including those who needed the additional-PTGBD after PTGBA. PATIENTS AND METHODS: We conducted a post hoc analysis of our multi-institutional data. This study included 63 patients who underwent LC after PTGBA, and we compared the surgical outcomes between the only-PTGBA group (n = 56) and the additional-PTGBD group (n = 7). RESULTS: No postoperative complications occurred among the 63 patients, and the postoperative hospital stay was 11 ± 12 days. Fourteen patients (22.2%) had a recurrence of cholecystitis, of whom 7 patients (11.1%) needed the additional-PTGBD after PTGBA. Significantly longer operative time (245 ± 74 vs 159 ± 65 min, P = 0.0017) and postoperative hospital stay (22 ± 27 vs 10 ± 9 d, P = 0.0118) and greater intraoperative blood loss (279 ± 385 vs 70 ± 208 mL, P = 0.0283) were observed among patients in the additional-PTGBD group compared with the only-PTGBA group, whereas the rates of postoperative complications (Clavien-Dindo grade ≥3: 0% each) and conversion to open surgery (28.6% vs 8.9%, P = 0.1705) were comparable. CONCLUSION: PTGBA for acute cholecystitis could result in good surgical outcomes of subsequent LC, especially regarding postoperative complications. However, we should keep in mind that the additional-PTGBD after PTGBA failure, which sometimes happened, would be associated with increased operative difficulty and longer recovery.

Index admission cholecystectomy for acute cholecystitis reduces 30-day readmission rates in pediatric patients.

BACKGROUND: Adult patients with cholecystitis who do not undergo cholecystectomy on index admission have worse outcomes, however, there is a paucity of data of the role of cholecystectomy during index hospitalization in the pediatric population. Our aim was to determine outcomes and readmission rates among pediatric patients with cholecystitis who underwent index cholecystectomy versus those who did not. METHODS: We performed a retrospective study of pediatric (< 18 years old) admitted with acute cholecystitis (AC) requiring hospitalization using the 2018 National Readmission Database (NRD). Exclusion criteria included age ≥ 18 years and death on index admission. Multivariable logistic regression was performed to identify factors associated with 30-day readmissions. RESULTS: We identified 550 unique index acute cholecystitis admissions. Mean age was 14.6 ± 3.0 years. Majority of patients were female (n = 372, 67.6%). Index cholecystectomy was performed in (n = 435, 79.1%) of cases. Thirty-day readmission rate was 2.8% in patients who underwent index cholecystectomy and 22.6% in those who did not (p < 0.001). On multivariable analysis, patients who did not undergo index cholecystectomy had higher odds of 30-day readmission than those who did not (OR 10.66, 95% CI 5.06-22.45, p < 0.001). Female patients also had higher odds of 30-day readmission compared to males (OR 3.37, 95% CI 1.31-8.69). CONCLUSIONS: Patients who did not undergo index cholecystectomy had over tenfold increase in odds of 30-day readmission. Further research is required to understand the barriers to index cholecystectomy despite society recommendations and clear clinical benefit.

Clinical correlation of cholelithiasis in patients undergoing percutaneous endoscopic gastrostomy.

The risk factor for cholelithiasis include low physical activity. With an aging society, the number of bedridden patients who undergo percutaneous endoscopic gastrostomy (PEG) has increased, and cholelithiasis has often been found in these patients. This study aimed to evaluate the risk factors correlated with cholelithiasis in adults who underwent PEG. This retrospective single-center design study reviewed patients who underwent PEG and were confirmed to have cholelithiasis through imaging from March 1996 to December 2021. The investigated variables were age, sex, body mass index (BMI, kg/m2), cause of PEG insertion, initial physical activity status, laboratory findings on PEG insertion day, and incidence of acute cholecystitis. The differences between categorical and continuous variables were analyzed using Student's t test and chi-square test. We enrolled 576 eligible patients who underwent PEG insertion. A total of 161 patients were detected with cholelithiasis (28.0%). The overall independent risk factors for cholelithiasis in patients who underwent PEG insertion were increased C-reactive protein (CRP) levels and decreased physical activity status (bedridden state). The incidence of cholelithiasis was increased by up to 30.7%, especially in patients with bedridden status. However, the incidence of acute cholecystitis among cholelithiasis group was only 5.6%. BMI and total cholesterol were positively correlated with the size of gallbladder (GB) stones. One of the major risk factors for cholelithiasis is decreased physical activity, especially in patients who underwent PEG insertion. Abdominal imaging is recommended to confirm the presence of cholelithiasis and to consider prophylaxis for cholelithiasis, especially in bedridden patients with elevated initial CRP levels at the time of PEG insertion.

[Acute non-calculous cholecystitis in a young aged patient with COVID-19: A case report].

To date, it is known that COVID-19 can lead to damage to various organs and systems, despite the statistical prevalence of respiratory manifestations of the disease. In some cases, in order to treat complications of coronavirus infection, a multidisciplinary approach may be required, including on an urgent basis. The article presents a clinical case of acute non-calculous cholecystitis in a 41-year-old patient with COVID-19. The importance of timely diagnosis and providing the possibility of emergency surgical care to patients with COVID-19, even under the conditions of the anti-epidemic regime, has been demonstrated.

Urgent laparoscopic cholecystectomy as a result of acute calculous cholecystitis in Pediatrics. / Colecistectomía laparoscópica urgente por colecistitis aguda litiásica en Pediatría.

INTRODUCTION: In spite of the increase in the prevalence of cholelithiasis in the last decades, no recommendations regarding the best treatment of acute calculous cholecystitis (AC) in Pediatrics have been developed. CLINICAL CASE: 4-year-old, 20kg male patient with no significant history referred to our institution as a result of abdominal sepsis. The blood count showed leukocytosis, with normal hemoglobin and bilirubin levels, and a normal liver function. The abdominal ultrasonography revealed cholelithiasis, gallbladder hydrops, and an inflammatory process compatible with appendicular plastron. In the diagnostic laparoscopy, the appendix was macroscopically normal, and acute cholecystitis was observed. Given the patient's situation, and in cooperation with the General Surgery Department, laparoscopic cholecystectomy was carried out. The patient recovered uneventfully on hospitalization day 5 under piperacillin-tazobactam treatment. DISCUSSION: There are no recommendations regarding AC treatment in children. In septic patients, cooperation between general and pediatric surgeons allows urgent cholecystectomy to be considered as a safe option.

INTRODUCCION: Pese al aumento en la prevalencia de colelitiasis durante las últimas décadas, no se han desarrollado recomendaciones sobre el mejor tratamiento de la colecistitis aguda litiásica (CA) en Pediatría. CASO CLINICO: Paciente varón de 4 años y 20 kg de peso sin antecedentes de interés, que acude derivado por sepsis de origen abdominal. Analíticamente destaca leucocitosis con hemoglobina, función hepática y bilirrubina normales. La ecografía abdominal muestra colelitiasis, hidrops vesicular y proceso inflamatorio compatible con plastrón apendicular. En laparoscopia diagnóstica se observa apéndice macroscópicamente normal y colecistitis aguda. Ante la situación del paciente se realiza, conjuntamente con Cirugía General, colecistectomía laparoscópica. El paciente se recupera sin incidencias tras 5 días de ingreso bajo cobertura con piperacilina-tazobactam. COMENTARIOS: No existen recomendaciones sobre el tratamiento de la CA en niños. En los pacientes sépticos, la colaboración entre cirujanos pediátricos y cirujanos generales permite contemplar la colecistectomía urgente como una opción segura.

A rare case of urothelial carcinoma metastasizing to the gallbladder wall with manifestations as acute cholecystitis.

BACKGROUND: Metastasis to the gallbladder is very rare. This case report highlights a rare cause of acute cholecystitis, which should be considered by the surgeon and other treating physicians in the differential diagnosis of patients with urothelial carcinoma. CASE: We report the case of a 73 year-old man with follow-up oncology care. He was diagnosed with infiltrating urothelial carcinoma in 2019, received neoadjuvant chemotherapy, and subsequently underwent radical cystectomy with ureteroileostomy in April 2020. Histology confirmed complete regression of bladder cancer, the lymphonodes were also free of tumour infiltration. In July 2021, the patient was examined for intermittent abdominal pain, predominantly of the right upper quadrant. On clinical examination, the gallbladder hydrops was palpable and a positive Murphy's sign was present. Due to the signs of acute cholecystitis, the patient was indicated for acute cholecystectomy. Gallbladder histology revealed metastatic involvement of the gallbladder wall by urothelial carcinoma. CONCLUSION: If patients with bladder cancer present with intermittent right subcostal pain or signs of acute cholecystitis and diagnostic imaging shows a thickened gallbladder wall, clinicians and radiologists should consider the possibility of metastatic origin of lesion.

What is the ideal timing of cholecystectomy after percutaneous cholecystostomy for acute cholecystitis?

BACKGROUND: Acute cholecystitis (AC) is one of the most prevalent diseases in clinical practice. Poor surgical candidates may benefit from early percutaneous cholecystostomy (PC) drainage followed by interval cholecystectomy (IC), which is the definitive treatment. The optimal timing between the PC drainage and the IC has not been identified. This study aimed to investigate how the duration between PC and IC affects perioperative outcomes and identify the optimal IC timing to minimize complications. METHODS: This retrospective cohort study included all adult patients diagnosed with AC who underwent PC followed by IC at a single institution center between 2014 and 2022. Patients with a history of hepatobiliary surgery, stones in the common bile duct, cirrhosis, active malignancy, or prolonged immunosuppression were excluded. The analysis did not include cases with major concurrent procedures during cholecystectomy, previously aborted cholecystectomies, or failure of the PC drain to control the inflammation. Linear and logistic regression models were used to analyze the impact of the interval between PC and IC on intra- and perioperative outcomes. RESULTS: One hundred thirty-two patients (62.1% male) with a mean age of 64.4 ± 15 (mean ± SD) years were diagnosed with AC (25% mild, 47.7% moderate, 27.3% severe). All patients underwent PC followed by IC after a median of 64 [48-91] days. Longer ICU stay was associated with longer time intervals between PC and IC (Coef 105.98, p < 0.001). No significant variations were detected in the intraoperative and perioperative outcomes between patients undergoing IC within versus after 8 weeks from PC placement. However, a higher percentage of patients with delayed IC (after 8 weeks) were discharged home (96.4% vs. 83.7%; p = 0.019). CONCLUSIONS: Patients may benefit from undergoing IC after the 8-week cutoff after PC. However, very long periods between PC and IC procedures may increase the risk of longer ICU stay.

Percutaneous cholecystostomy as a definitive treatment for acute acalculous cholecystitis: clinical outcomes and risk factors for recurrent cholecystitis.

OBJECTIVE: To investigate the outcomes of percutaneous cholecystostomy (PC) as a definitive treatment for acute acalculous cholecystitis (AAC) and to identify the risk factors for cholecystitis recurrence after catheter removal. METHODS: Between January 2008 and December 2017, 124 patients who had undergone PC as definitive treatment for moderate or severe AAC. The initial clinical success, complications, and recurrent cholecystitis after PC removal were retrospectively assessed. Twenty-one relevant variables were analyzed to identify risk factors for recurrent cholecystitis. RESULTS: Clinical effectiveness was achieved in 107 patients (86.3%) at 3 days and in all patients (100%) at 5 days after PC placement. Six Grade 2 adverse events occurred, including catheter dislodgement (n = 3) and clogging (n = 3), which required catheter exchange. The PC catheter was removed in 123 patients (99.2%), with a median indwelling duration of 18 days (range 5-116 days). During the follow-up period (median, 1624 days; range, 40-4945 days), five patients experienced recurrent cholecystitis (4.1%). The cumulative recurrence rates were 3.3%, 4.1%, and 4.1% at 6 months, 1 year, and 5 years, respectively. Multivariate analysis revealed that an age-adjusted Charlson comorbidity index (aCCI)≥7 positively correlated with recurrence (OR, 1.97; 95% confidence interval, 1.07-3.64; p = 0.029). CONCLUSIONS: Definitive PC is a safe and effective treatment option for patients with AAC. The PC catheters can be safely removed in most patients. An aCCI≥7 was a risk factor for cholecystitis recurrence after catheter removal. ADVANCES IN KNOWLEDGE: 1. Percutaneous cholecystostomy (PC) is a safe and effective as a definitive treatment in patients with acute acalculous cholecystitis (AAC).2. PC can be safely removed after recover from AAC in the majority of patients (99.2%) with low rate of recurrence of cholecystitis (4.1%).3. Age-adjusted Charlson comorbidity index ≥7 was a risk factor for recurrence of cholecystitis after PC removal.

Post-cesarean section laparoscopic cholecystectomy: a case report.

BACKGROUND: Laparoscopic cholecystectomy at the time of cesarean section is novel in medicine. It is safe, feasible, and cost-effective. CASE PRESENTATION: A 29-year-old G3P2 + 0 woman had two previous cesarean sections. She was pregnant at 32 weeks. The fetus had anencephaly. She had acute cholecystitis. Laparoscopic cholecystectomy done at the time of termination of pregnancy by cesarean section. CONCLUSIONS: In a critical period, such as acute cholecystitis, the combination of laparoscopic cholecystectomy immediately post cesarean section is effective if the surgeon is highly qualified and experienced.

Transarterial embolisation of cystic artery pseudo aneurysm: a rare complication of acute cholecystitis.

Pseudo aneurysm of cystic artery is an extremely rare complication which may occur in association with cholecystitis, liver biopsy, biliary interventions, pancreatitis and laparoscopic cholecystectomy. We report the case of a 55 years old male patient who presented with complaint of right upper quadrant pain, haematemesis and melena, he underwent CT scan abdomen that revealed perforated gall bladder with cystic artery pseudo aneurysm secondary to acute cholecystitis. An angiogram was performed that confirmed small cystic artery pseudo aneurysm. Selective embolisation of cystic artery was done, resulting in complete exclusion of pseudo aneurysm. The patient recovered completely.

A novel approach to distinguish complicated and non-complicated acute cholecystitis: Decision tree method.

It is difficult to differentiate between non-complicated acute cholecystitis (NCAC) and complicated acute cholecystitis (CAC) preoperatively, which are two separate pathologies with different management. The aim of this study was to create an algorithm that distinguishes between CAC and NCAC using the decision tree method, which includes simple examinations. In this retrospective study, the patients were divided into 2 groups: CAC (149 patients) and NCAC (885 patients). Parameters such as patient demographic data, American Society of Anesthesiologists (ASA) score, Tokyo grade, comorbidity findings, white blood cell (WBC) count, neutrophil/lymphocyte ratio, C-reactive protein (CRP) level, albumin level, CRP/albumin ratio (CAR), and gallbladder wall thickness (GBWT) were evaluated. In this algorithm, the CRP value became a very important parameter in the distinction between NCAC and CAC. Age was an important predictive factor in patients with CRP levels >57 mg/L, and the critical value for age was 42. After the age factor, the important parameters in the decision tree were WBC and GBWT. In patients with a CRP value of ≤57 mg/L, GBWT is decisive and the critical value is 4.85 mm. Age, neutrophil/lymphocyte ratio, and WBC count were among the other important factors after GBWT. Sex, ASA score, Tokyo grade, comorbidity, CAR, and albumin value did not have an effect on the distinction between NCAC and CAC. In statistical analysis, significant differences were found groups in terms of gender (34.8% vs 51.7% male), ASA score (P < .001), Tokyo grade (P < .001), comorbidity (P < .001), albumin (4 vs 3.4 g/dL), and CAR (2.4 vs 38.4). By means of this algorithm, which includes low-cost examinations, NCAC and CAC distinction can be made easily and quickly within limited possibilities. Preoperative prediction of pathologies that are difficult to manage, such as CAC, can minimize patient morbidity and mortality.
