The gallbladder pathology is mainly represented by cholelithiasis, treated with cholecystectomy, one of the most commonly performed surgical procedures, continues to raise some challenges. Despite the advancements in surgical techniques, especially in those patients presenting some particularities, such as cirrhotic patients or those with sclero-atrophic or acute gangrenous cholecystitis, difficulties continue to arise. This review, including an evaluation of the literature from the last 20 years, aims to explore the pathophysiological mechanisms and surgical approaches for these high-risk conditions. Emphasis is placed on tailoring management strategies in order to reduce complications and improve outcomes, offering insights for optimizing care in difficult cholecystectomies. Full article

Background: This systematic review aimed to comprehensively evaluate the clinical, diagnostic, and therapeutic features of synchronous acute cholecystitis (AC) and acute appendicitis (AAP). Methods: The review protocol was prospectively registered in PROSPERO (CRD420251086131) and conducted in accordance with PRISMA 2020 guidelines. A systematic search was performed across PubMed, MEDLINE, Web of Science, Scopus, Google Scholar, and Google databases for studies published from January 1975 to May 2025. Search terms included variations of “synchronous,” “simultaneous,” “concurrent,” and “coexistence” combined with “appendicitis,” “appendectomy,” “cholecystitis,” and “cholecystectomy.” Reference lists of included studies were screened. Studies reporting human cases with sufficient patient-level clinical data were included. Data extraction and quality assessment were performed independently by pairs of reviewers, with discrepancies resolved through consensus. No meta-analysis was conducted due to the descriptive nature of the data. Results: A total of 44 articles were included in this review. Of these, thirty-four were available in full text, one was accessible only as an abstract, and one was a literature review, while eight articles were inaccessible. Clinical data from forty patients, including two from our own cases, were evaluated, with a median age of 41 years. The gender distribution was equal, with a median age of 50 years among male patients and 36 years among female patients. Leukocytosis was observed in 25 of 33 patients with available laboratory data. Among 37 patients with documented diagnostic methods, ultrasonography and computed tomography were the most frequently utilized modalities, followed by physical examination. Twenty-seven patients underwent laparoscopic cholecystectomy and appendectomy. The remaining patients were managed with open surgery or conservative treatment. Postoperative complications occurred in five patients, including sepsis, perforation, leakage, diarrhea, and wound infections. Histopathological analysis revealed AAP in 25 cases and AC in 14. Additional findings included gangrenous inflammation and neoplastic lesions. Conclusions: Synchronous AC and AAP are rare and diagnostically challenging conditions. Early recognition via imaging and clinical evaluation is critical. Laparoscopic management remains the preferred approach. Histopathological examination of surgical specimens is essential for identifying unexpected pathology, thereby guiding appropriate patient management. Full article

Background: Acute complicated cholecystitis (ACC) is associated with prolonged hospitalization, increased morbidity, and higher mortality. However, objective imaging-based criteria to guide early clinical decision-making remain limited. This study aimed to develop a predictive scoring system integrating clinical characteristics, laboratory biomarkers, and computed tomography (CT) findings to facilitate the early identification of ACC in the emergency department (ED). Methods: We conducted a retrospective study at an urban tertiary care center in Taiwan, screening 729 patients who presented to the ED with suspected cholecystitis between 1 January 2018 and 31 December 2020. Eligible patients included adults (≥18 years) with a confirmed diagnosis of acute cholecystitis based on the Tokyo Guidelines 2018 (TG18) and who were subsequently admitted for further management. Exclusion criteria included (a) the absence of contrast-enhanced CT imaging, (b) no hospital admission, (c) alternative final diagnosis, and (d) incomplete clinical data. A total of 390 patients met the inclusion criteria. Demographic data, laboratory results, and CT imaging features were analyzed. Logistic regression and decision tree analyses were used to construct predictive models. Results: Among the 390 included patients, 170 had mild, 170 had moderate, and 50 had severe cholecystitis. Key predictors of ACC included gangrenous changes, gallbladder wall attenuation > 80 Hounsfield units, CRP > 3 mg/dL, and WBC > 11,000/μL. A novel scoring system incorporating these variables demonstrated good diagnostic performance, with an area under the curve (AUC) of 0.775 and an optimal cutoff score of ≥2 points. Decision tree analysis similarly identified these four predictors as critical determinants in stratifying disease severity. Conclusions: This CT- and biomarker-based scoring system, alongside a decision tree model, provides a practical and robust tool for the early identification of complicated cholecystitis in the ED. Its implementation may enhance diagnostic accuracy and support timely clinical intervention. Full article

Background: This study investigated the reasons for transferring patients to tertiary hospitals due to complications arising after surgery at orthopedic specialty hospitals and the treatment results. Methods: This retrospective cohort study was conducted on all orthopedic patients, except for the spine, at a single institution from January 2012 to May 2022. Results: Of 67,118 patients, 167 (0.24%) were transferred to a tertiary hospital after surgery. Patients’ average age was 72.2 ± 9.2 years (range: 28–91 years), and there were 34 men and 133 women. The most common reason for transfer to a tertiary hospital was pulmonary embolism (27 patients, 16.2%), which occurred on an average 3.81 days (range: 0–23 days) after surgery, and 25 patients were transferred within 1 week after surgery. The next most common cause was acute cholecystitis (19 patients (11.4%), all of whom had undergone total knee arthroplasty), which occurred on an average 6.15 days (range: 1–14 days) after surgery. Conclusions: The rate of transfer from the orthopedic hospital where this study was conducted to a tertiary hospital was very low at 0.24%. Pulmonary embolism, acute cholecystitis, and cerebral infarct were the most common reasons for transfer. In particular, acute cholecystitis was the second most common reason for transfer, and caution should be taken because elderly patients may experience only atypical clinical symptoms without abdominal pain or tenderness even the day after surgery.

Background and Objectives: Early cholecystectomy (EC) is widely regarded as the first-line treatment for acute calculous cholecystitis (ACC). Current debate centers on the feasibility of EC as an option even for elderly patients. This study aims to determine whether age alone is an independent risk prediction factor for prognosis after EC for ACC. Materials and Methods: This study is a post-hoc analysis of the S.P.Ri.M.A.C.C. WSES prospective international multicenter observational study database, including patients with ACC undergoing EC. Univariate and multivariate analyses were conducted, examining different risk factors for major morbidity and mortality after EC. Results: In the univariate analyses, age was found to be a statistically significant risk factor for both 30-day major complications (p < 0.001) and 30-day mortality (p = 0.003). However, in the multivariate analysis, age alone was not a significant predictor for either outcome, with p-values of 0.419 and 0.094, respectively. The only significant risk factor associated with both 30-day mortality and major morbidity in the multivariate model was the POSSUM Physiological Score (PS). Conclusions: Age alone cannot be considered a reliable risk predictor for a complicated postoperative course after EC in patients with ACC. Frailty, rather than chronological age, should be assessed to predict the outcome of these patients. Full article

The Bosniak classification categorizes renal cystic lesions based on cross-sectional imaging features from clearly benign (Bosniak type I) to malignant lesions (Bosniak type IV). A 67-year-old female patient presented to the emergency department with typical symptoms of acute cholecystitis. During a transabdominal ultrasound examination, an incidental finding was a suspicious cluster of anechoic cystic lesions with internal septa in the left kidney. Following contrast-enhanced computed tomography (CT), the lesion was categorized as a Bosniak type IV cyst. Compared to an earlier CT scan, a Bosniak type I cyst preceded the current Bosniak type IV cyst, suggesting a malignant alteration over the 7-year interval. It was surgically removed, and pathohistological analysis revealed cystic renal cell carcinoma. Although simple renal cysts rarely become malignant, scientific discussion about potential algorithms for additional surveillance is needed. Full article

Gallbladder carcinoma (GBC) is one of the most aggressive malignancies of the biliary tract, often originating from chronic inflammation associated with gallstones and cholecystitis. Persistent inflammation plays a pivotal role in the development of preneoplastic changes, such as metaplasia, which may progress to malignancy. Despite its relatively low incidence, GBC is characterized by a poor prognosis due to late-stage diagnosis, highlighting the urgent need for improved early detection strategies. This study aimed to assess the diagnostic and prognostic significance of CA 19-9 and CEA levels in patients with gallbladder lesions, while also evaluating systemic inflammation and hemostatic dysregulation. A retrospective analysis was conducted on patients diagnosed with gallbladder lesions, with histopathological confirmation of adenocarcinoma and metaplasia. Laboratory assessments included serum levels of tumour markers, inflammatory markers such as CRP, and key hemostatic parameters, including thrombocyte count, prothrombin time (PT), activated partial thromboplastin time (aPTT), and fibrinogen levels. A predictive scoring model was developed using the cutoff values of CA 19-9 and CEA to assess their combined diagnostic potential. Among the patients studied, 48.9% had an initial diagnosis of chronic cholecystitis, while 32.2% presented with acute cholecystitis. Adenocarcinoma was identified in 6.7% of cases after histopathological examination, predominantly in females over 65 years old with acute cholecystitis. Metaplasia was detected in 7.8% of cases, primarily in elderly females with chronic cholecystitis. Laboratory findings revealed significantly elevated levels of CA 19-9, CEA, AFP, and CA-125 in patients with adenocarcinoma. Additionally, abnormalities in hemostatic parameters, including increased fibrinogen levels and alterations in thrombocyte count, were observed in patients with malignancy. A combined predictive score using CA 19-9 and CEA demonstrated strong potential for detecting adenocarcinoma and metaplasia, improving diagnostic accuracy. Our findings emphasize the clinical importance of integrating tumour markers, inflammatory biomarkers, and hemostatic parameters in the evaluation of gallbladder lesions associated with chronic inflammation. The combined assessment of these factors enhances early detection, facilitates malignancy risk stratification, and improves prognostic evaluation, particularly in patients with metabolic and cardiovascular comorbidities.

The worldwide prevalence of gallstones (GSs) is estimated to be between 10% and 15% in the general population. Gallbladder carcinoma (GBC) is the most common biliary tract neoplasia, and it is characterized by highly aggressive behavior and poor overall prognosis. Long-standing GSs and chronic inflammatory state represent the most common risk factors for GBC, promoting a carcinogenic microenvironment. Long-standing GSs expose patients to potentially severe surgical and oncological complications. A 71-year-old gentleman, who had never experienced biliary symptoms and had diabetes mellitus (DM), presented with severe peritonitis due to perforated acute calculous cholecystitis. The patient underwent an emergent laparotomic cholecystectomy. Histopathology found a rare pT2b poorly differentiated squamocellular carcinoma of the gallbladder. Although more difficult due to the concomitant inflammatory context, it is critical to identify suspicious lesions during preoperative imaging in patients at high risk of malignancy presenting with complex acute gallbladder pathologies. A review of the literature was conducted to gain a deeper insight into the relationship between long-standing GSs and GBC, evaluating also the difficult diagnosis and management of malignancy in the acute setting. Considering the existing literature, the choice to pursue a prophylactic cholecystectomy may be justifiable in selected asymptomatic GS patients at high risk for GBC. Full article

Gallstone disease (GSD) is a common gastrointestinal disorder affecting approximately 10–20% of the global adult population, characterized by the presence of gallstones, predominantly cholesterol-based, in the gallbladder and/or biliary ducts. While many patients remain asymptomatic, more than 20% develop clinical symptoms such as abdominal pain, nausea, vomiting, jaundice, and anorexia, potentially leading to severe complications like acute cholecystitis and biliary pancreatitis. GSD has a significant genetic predisposition, with the variable prevalence of the disease according to ethnicity being highest in American and European countries and lowest in Asian and African populations. Numerous genes encoding membrane transporters involved in bile metabolism are associated with GSD, including in particular members of ATP-binding cassette transporters and others, which affect bile lithogenicity and contribute to the development of gallstones. Specific mutations in these genes are linked to an increased risk of gallstone formation, especially in individuals with certain hereditary conditions such as hemolytic diseases, thyroid disorders, and hyperparathyroidism. Advances in genetic studies have identified new variants that influence the risk of cholelithiasis, although the exact mechanisms remain partially understood in many cases. This review briefly summarizes the genetic causes of cholelithiasis, highlighting various pathogenetic mechanisms. It presents the currently used treatments and the potential implications of widely applied genetic diagnostics. Full article

Emergency endoscopy is an activity that must be guaranteed 7 days a week and 24 h a day. The pathologies of endoscopic interest that require emergency intervention are mainly hemorrhages of the upper digestive tract, the removal of foreign bodies, and the ingestion of caustics. The emergency endoscopist must therefore be experienced in the management of these pathologies. Nowadays, however, we know that even some biliary tract pathologies must be managed within a variable period between 12 and 72 h, in particular acute cholangitis (Ach), acute biliary pancreatitis (ABP), biliary duct leaks (BDLs), and acute cholecystitis (AC). If, on one hand, there is little awareness among doctors about which pathologies of the biliary tract really deserve urgent treatment, on the other, the international guidelines, although not uniformly, have acquired the results of the studies and have clarified that only severe Ach should be treated within 12 h; in other cases, endoscopic treatment can be delayed up to 72 h according to the specific condition. This obviously has a significant organizational implication, as not all endoscopists have training in biliary tract endoscopy, and guaranteeing the availability of a biliary endoscopist 24/7 may be incompatible with respecting the working hours of individual professionals. This review aims to evaluate which pathologies of the biliary tract really require an endoscopic approach in emergency or urgency and the organizational consequences that this can determine. Based on the guidelines, we can conclude that a daytime availability for urgent biliary tract procedures 7 days a week should be provided for the management of severe ACh. Patients with ABP, AC unfit for surgery, and not responsive to medical therapy or BDLs can be treated over a longer period, allowing its scheduling on the first available day of the week.

Background and Objectives: Acute pancreatitis (AP) is an inflammatory disease where there is autodigestion of the pancreas by prematurely activated enzymes which may lead to a systemic inflammatory response. The aim of our study was to investigate the levels of circulating serum leukotriene B4 (LTB4), lipoxin A4 (LXA4), and resolvin D1 (RvD1) in pancreatitis due to gallstones in the etiologic investigation of AP. Materials and Methods: A total of 147 patients with AP (n: 49), AC (n: 49), and combined AP + AC (n: 49) will be included in the study. Healthy volunteers (n: 49) will be included as the control group. Results: RvD1 levels were significantly lower in patient groups compared to controls, while LXA4 levels were lower in patients with combined AP + AC (145.24 ng/L) compared to both controls (312.36 ng/L) and other patient groups. LTB4 levels were elevated in all patient groups compared to controls (335.56 ng/L vs. 65.56 ng/L) and were highest in combined AP + AC. Significant correlations were identified: RvD1 showed a negative correlation with LTB4 (r =−0.676; p < 0.001) and a positive correlation with LXA4 (r = 0.563, p < 0.001). ROC analysis demonstrated high diagnostic accuracy, with LXA4 and LTB4 achieving perfect differentiation (AUC: 1.0) between control and combined AP + AC cases. Conclusions: Our study showed that serum RvD1 and LXA4 levels have powerful anti-inflammatory properties in accordance with the literature. LTB4 may represent new, effective indicators to predict the severity of AP and the presence of necrosis in patients with AP. Despite its low sensitivity and specificity, RvD1 could be used as a complementary marker to the current scoring systems for the initial assessment of AP prognosis. These findings provide a new mechanistic understanding of how RvD1 attenuates inflammation to facilitate resolution, which could help develop novel therapeutic strategies for diseases caused by unresolved inflammation. It is easily obtainable and can provide additional prognostic information to clinicians. Full article

Background: Laparoscopic cholecystectomy for acute cholecystitis carries an increased risk of biliovascular injuries. Fluorescence cholangiography (FC) is a valuable diagnostic tool for identifying extrahepatic bile ducts (EHBD). The objective of this study was to evaluate the efficacy of FC in delineating EHBD anatomy, both before and after dissection, based on the critical view of safety (CVS) principles. Methods: Urgently admitted patients were prospectively stratified into two groups, depending on whether they had mild or moderate acute cholecystitis, in accordance with the 2018 Tokyo guidelines. All patients were scheduled for an early laparoscopic cholecystectomy using FC and were administered a fixed dose of indocyanine green (ICG) intravenously 12 h prior to the surgical procedure. Results: A total of 108 patients—75 patients with mild acute cholecystitis and 33 patients with moderate acute cholecystitis—were included. More than four CVS steps were performed in 101 patients (93.5%). Less than four CVS steps were performed only in seven patients—three (2.5%) patients with mild acute cholecystitis and four (4%) patients with moderate acute cholecystitis. The achievement of the CVS principles and the visualization rate using FC significantly increased in both patient groups, ranging from 3% before CVS to 100% after CVS (p < 0.001). In both groups, the cystic duct was visualized in most patients after CVS and FC, followed by the common bile duct and the common hepatic duct. Conversely, even after using CVS and FC, the visualization of the confluence of the cystic and common hepatic ducts remained less likely and challenging in both groups (57.3% in mild patients vs. 33.3% in moderate patients; p = 0.022). Background liver fluorescence disturbance was observed equally in both patient groups (6–11%), but it did not reach statistical significance. The median operative time was 60 ± 25 min in patients with mild acute cholecystitis compared to 85 ± 37 min in patients suffering from moderate acute cholecystitis (p < 0.001). No postoperative complications or biliovascular injuries were observed. Conclusions: FC is a convenient, safe, and efficacious procedure for attaining CVS principles and identifying the EHBD anatomy in most patients. The procedure showed superior results in mild acute cholecystitis patients in comparison to moderate acute cholecystitis patients. Full article

Endoscopic management of benign pancreaticobiliary disorders encompasses a range of procedures designed to address complications in gallstone disease, choledocholithiasis, and pancreatic disorders. Acute cholecystitis is typically treated with cholecystectomy or percutaneous drainage (PT-GBD), but for high-risk or future surgical candidates, alternative decompression methods, such as endoscopic transpapillary gallbladder drainage (ETP-GBD), and endoscopic ultrasound (EUS)-guided gallbladder drainage (EUS-GBD), are effective. PT-GBD is associated with significant discomfort as well as variable adverse event rates. EUS-GBD leverages lumen-apposing metal stents (LAMS) for direct access to the gallbladder, providing the ability to treat an inflamed GB internally. Choledocholithiasis is primarily managed with ERCP, utilizing techniques to include balloon extraction, mechanical lithotripsy, or advanced methods such as electrohydraulic or laser lithotripsy in cases of complex stones. Altered anatomy from bariatric procedures like Roux-en-Y gastric bypass may necessitate specialized approaches, including balloon-assisted ERCP or EUS-directed transgastric ERCP (EDGE). Post-operative complications, including bile leaks and strictures, are managed endoscopically using sphincterotomy and stenting. Post-liver transplant anastomotic and non-anastomotic strictures often require repeated stent placements or advanced techniques like magnetic compression anastomosis in refractory cases. In chronic pancreatitis (CP), endoscopic approaches aim to relieve pain and address structural complications like pancreatic duct (PD) strictures and calculi. ERCP with sphincterotomy and stenting, along with extracorporeal shock wave lithotripsy (ESWL), achieves effective ductal clearance for PD stones. When traditional approaches are insufficient, direct visualization with peroral pancreatoscopy-assisted lithotripsy is utilized. EUS-guided interventions, such as cystgastrostomy, pancreaticogastrostomy, and celiac plexus blockade, offer alternative therapeutic options for pain management and drainage of peripancreatic fluid collections. EUS plays a diagnostic and therapeutic role in CP, with procedures tailored for high-risk patients or those with complex anatomy. As techniques evolve, endoscopic management provides minimally invasive alternatives for patients with complex benign pancreaticobiliary conditions, offering high clinical success and fewer complications.

Background and Objectives: The aim of the present study was to calculate HALP and modified HALP scores for patients diagnosed with acute cholecystitis (AC) and to determine the predictive utility of these scores for surgical timing and morbidity in patients who underwent surgery for AC. Materials and Methods: This study included data from 641 patients who underwent surgery for AC between January 2010 and May 2023. The HALP score was calculated using the formula hemoglobin (g/L) × albumin (g/L) × lymphocyte (10⁹/L)/platelets (10⁹/L). The modified HALP score was calculated using the formula hemoglobin (g/L) × albumin (g/L) × lymphocyte (10⁹/L) × platelets (10⁹/L). Results: The mean HALP score was 46.81, and the mean modified HALP score was 2,758,401.21. Laparoscopic cholecystectomy (LC) was successfully completed in 582 (90.8%) patients. When examining the relationship between HALP and modified HALP scores and the procedure type, a statistically significant difference was found in the distribution of median HALP and modified HALP scores between the LC and laparoscopic and open cholecystectomy (LTOC) groups. For patients with a HALP score < 34.43 and modified HALP score < 2,077,019, the likelihood of conversion to open surgery increased, with a sensitivity of 65.5% vs. 58.8% and a specificity of 66.1% vs. 59.3%. In patients who underwent surgery, there was a significant difference in the LTOC between the HALP score and modified HALP score cut-off groups (p < 0.001 and, p = 0.007). Conclusions: Evaluation of the HALP score is a promising and valuable assessment method for designing appropriate treatment and management strategies for patients with AC. Full article

Background: Cholelithiasis is a rare disease in infants, and there is limited data on its risk factors and management. Objectives: To evaluate the risk factors, management, and response to medical treatment of cholelithiasis in infants. Methods: Infants diagnosed with cholelithiasis by ultrasound between 2018 and 2023 were retrospectively analyzed. Details of patient history, imaging findings, current symptoms, and treatments were reviewed. Results: Over 5 years, 98 infants were diagnosed with cholelithiasis. Thirty-three (33.7%) were girls, and the most common risk factors were the use of cephalosporin antibiotic therapy in 46.9%, sepsis in 30.6%, total parenteral nutrition in 29.6%, prematurity in 27.6%, congenital heart disease in 18.4%, and genetic disease (Down syndrome diagnosis in seven patients) in 16.3%. Only fifteen patients (15.3%) were symptomatic. Ursodeoxycholic acid (UDCA) treatment was given to 90.8% of patients, but nine of them used it for a short period or irregularly, and regular users were 81.6%. Gallstones disappeared in 46 patients (46.9%), including 14 (30.4%) without using UDCA regularly. The response rate to UDCA treatment was lower in preterm infants (p = 0.004). Gallstone resolution was higher in the nonusers, 14/18 (77.8%) versus 32/79 (40.5%) (p = 0.03). Acute cholecystitis was observed in only four patients; no other complications were noted. No infant required surgical or endoscopic treatment. Conclusions: UDCA should not be used routinely in children, especially infants, except in symptomatic children with a contraindication to surgery or to reduce clinical symptoms. In the absence of symptoms, patients may be monitored clinically. Full article
