The objective of this study was to evaluate and compare the histopathological, clinical, and treatment characteristics of xanthogranulomatous cholecystitis (XGC) in patients undergoing cholecystectomy at a single center. Aim: We aim to enhance the understanding of its presentation and improve its differential diagnosis from other gallbladder pathologies. Methods: We retrospectively reviewed 6783 cholecystectomy cases performed between January 2015 and January 2023 at the General Surgery Clinic of Haydarpaşa Numune Training and Research Hospital, and a diagnosis of xanthogranulomatous cholecystitis was histopathologically established in 131 patients. In this retrospective study, we examined the clinicopathological characteristics, preoperative imaging methods and findings, histopathological images, surgical procedure methods, and postoperative complications of 131 patients. Results: The study included 131 patients, with ages ranging from 18 to 88 years, of which 74 (56.5%) were female and 57 (43.5%) were male. Ultrasound imaging was performed on 128 patients. Ultrasound imaging revealed wall thickening in 72.7% of cases, hypoechoic nodules in 13.3%, biliary tract pathologies in 10.9%, and adenomyomatosis in 3.1%. A total of 59 cases had MRI. On MRI, wall thickening was observed in 50.8% of cases, biliary tract pathologies in 33.9%, adenomyomatosis in 10.2%, hypoechoic nodules in 3.4%, and hypoechoic nodules + wall thickening (HN + WT) in 1.7%. Histopathological diagnosis was diffuse in 79.4% of cases and focal in 20.6%. In addition to cholecystectomy, non-surgical interventions were not required in 77.1% of the cases, while 11.5% underwent ERCP, 9.2% underwent percutaneous procedures, 1.5% underwent both ERCP and percutaneous procedures, and 0.8% underwent other non-surgical interventions. Of the surgeries, 93.1% were elective and 6.9% were emergency. Postoperative complications were not observed in 84% of the patients; 5.3% experienced surgical complications, 5.3% had surgical site infection, and 5.3% had other complications (pneumonia and urinary infection). The length of hospital stay ranged from 0 to 26 days, with a mean of 5.27 ± 4.59 days and a median of 4 days. Conclusions: Xanthogranulomatous cholecystitis is a rare disease of the gallbladder with no characteristic radiological or clinical findings and can often be confused with gallbladder cancer. Further studies involving larger populations are needed to improve the preoperative diagnosis. [ABSTRACT FROM AUTHOR]

Background: Transgender individuals frequently undergo gender-affirming hormone therapy (GAHT) during their gender transition which plays a vital role in gender identity affirmation. Cholelithiasis, a common condition affecting 10-15% of the US population, has been linked to estrogen therapy in cisgender women. Despite the fact that hormonal profiles achieved after GAHT are not always identical to cisgender individuals, the effects of GAHT on gallbladder disease (GBD) risk have not been evaluated in transgender populations. This research aims to address this gap utilizing a large nationwide database. Methods: The study analyzed medical records data from the TrinetX database from 52,847 trans men and 38,114 trans women. Four cohorts were created: trans women and men either receiving either hormone therapy or no intervention. Descriptive statistics were calculated before matching to estimate disease burden. The groups were then propensity score matched on known risk factors (age, race, BMI, etc.) and rates of GBD were compared. Results: Before matching, trans women on hormone therapy (TWHT) had a significantly higher 10-year GBD probability than those naïve to therapy (TWNI) (4.69% vs 1.88%). For trans men, there was no significant difference in 10-year rates between those on therapy (TMHT) and those not (TMNI) (3.15% vs 3.87%). Cholecystectomy rates were significantly higher for TWHT than TWNI (1.10% vs. 0.57%), but similar between TMHT and TMNI (0.95% vs. 1.10%). After accounting for risk factors, TWHT had increased GBD risk (HR 1.832), while TMHT showed no significant change. Discussion: This study suggests a link between estrogen GAHT and increased GBD risk in transgender women. Notably, testosterone GAHT did not offer protection against GBD in transgender men, contrary to expectations. This study is, to our knowledge, the first to describe the burden of GBD in the transgender population and to investigate the effects of GAHT on GBD risk. [ABSTRACT FROM AUTHOR]

Background Cholecystectomy, a type of surgery commonly performed globally, has possible mutual effects on the socioeconomic conditions of different countries due to various postoperative recovery times. Aims This study evaluated the medical and socioeconomic factors affecting delayed return-to-work (RTW) time after elective cholecystectomy. Methods This retrospective study analysed patients who underwent elective cholecystectomy for benign gallbladder diseases from January 2022 to April 2023. The patients' medical and socioeconomic data were collected to investigate the clinical and socioeconomic factors correlated with RTW time of >30 days after surgery. Results This study included 180 consecutive patients. Significant correlations were found between delayed RTW time (>30 days) and age (odds ratio [OR]: 1.059, 95% confidence interval [CI] 1.008–1.113, P  = 0.024), lack of medical insurance (OR: 2.935, 95% CI 1.189–7.249, P  = 0.02) and high-intensity labour jobs (OR: 3.649, 95% CI 1.495–8.909, P  = 0.004). Patients without medical insurance (26.6 versus 18.9 days) and those with high-intensity labour jobs (23.9 versus 18.8 days) had a higher mean RTW time than those with insurance and a less-intense labour job (P  < 0.001). Conclusions After cholecystectomy, older age, lack of medical insurance and high-intensity labour job were correlated with a delayed RTW time. Informing patients about their expected RTW time after surgery can help reduce costs. [ABSTRACT FROM AUTHOR]

The influence of metabolic dysfunction-associated steatotic liver disease (MASLD) on gallbladder polyp development in both sexes remains elusive. Therefore, to clarify the role of MASLD in gallbladder polyp development, we investigated the longitudinal association between MASLD and gallbladder polyps. In this observational study, we included 5,527 gallbladder polyp-free patients who underwent > 2 health check-ups over > 2 years. Generalized estimation equations were used to analyze associations between MASLD and gallbladder polyp development according to repeated measures at baseline and the most recent stage. Gallbladder polyp development rates in men and women were 7.5% and 5.6% (p < 0.01), respectively. MASLD was not significantly correlated with gallbladder polyp development. Regarding the association between gallbladder polyp development (men: ≥6 mm and women: ≥5 mm) and the number of MASLD components following lifestyle habits, men and women with ≥ 4 MASLD components had odds ratios of 3.397 (95% confidence interval: 1.096–10.53) and 5.338 (1.054–27.04), respectively. Higher nonalcoholic fatty liver disease fibrosis scores were associated with significant risk of gallbladder polyp development in women (1.991, 1.047–3.785). Although MASLD influence on gallbladder polyp development differs by sex, close monitoring of patients with an increasing number of MASLD components is essential to prevent gallbladder polyp development. Specifically, men with ≥ 4 MASLD components should be monitored for gallbladder polyps measuring ≥ 6 mm. [ABSTRACT FROM AUTHOR]

Aims: To evaluate the safety profile of robotic cholecystectomy performed within the United Kingdom (UK) Robotic Hepatopancreatobiliary (HPB) training programme. Methods: A retrospective evaluation of prospectively collected data from eleven centres participating in the UK Robotic HPB training programme was conducted. All adult patients undergoing robotic cholecystectomy for symptomatic gallstone disease or gallbladder polyp were considered. Bile duct injury, conversion to open procedure, conversion to subtotal cholecystectomy, length of hospital stay, 30-day re-admission, and post-operative complications were the evaluated outcome parameters. Results: A total of 600 patients were included. The median age was 53 (IQR 65–41) years and the majority (72.7%; 436/600) were female. The main indications for robotic cholecystectomy were biliary colic (55.5%, 333/600), cholecystitis (18.8%, 113/600), gallbladder polyps (7.7%, 46/600), and pancreatitis (6.2%, 37/600). The median length of stay was 0 (IQR 0–1) days. Of the included patients, 88.5% (531/600) were discharged on the day of procedure with 30-day re-admission rate of 5.5% (33/600). There were no bile duct injuries and the rate of conversion to open was 0.8% (5/600) with subtotal cholecystectomy rate of 0.8% (5/600). Conclusion: The current study confirms that robotic cholecystectomy can be safely implemented to routine practice with a low risk of bile duct injury, low bile leak rate, low conversion to open surgery, and low need for subtotal cholecystectomy.

Background: This study aimed to summarize evidence of ursodeoxycholic acid (UDCA) use in the management of hepatobiliary diseases, present indications for UDCA use in Korea, and reimbursement criteria for UDCA use in the country. Current Concepts: UDCA is currently approved for the treatment and prevention of gallstone in obese patients with rapid weight loss after post-bariatric surgery, primary biliary cirrhosis (PBC), chronic liver disease with markedly elevated liver function test values, and chronic hepatitis C. However, the approval and reimbursement criteria for UDCA depend on the dose, specific diseases, and circumstances. UDCA is administered at doses of 100, 200, and 300 mg. The 100 mg dose is available over-the-counter, whereas a prescription is required for the 200 and 300 mg doses. The approval standards differed by dose: UDCA 100 mg for biliary diseases and chronic liver disease; UDCA 200 mg for gallstone, PBC, and chronic hepatitis C; and UDCA 300 mg for PBC, gallstone prevention in obese patients, and patients who had undergone gastrectomy. Co-administration of UDCA with antiviral drugs may require patients to bear some costs. UDCA can be combined with either milk thistle or biphenyl dimethyl dicarboxylate but not both. Discussion and Conclusion: UDCA is a relatively safe medication with many benefits. The current reimbursement standards for hepatobiliary diseases include chronic liver disease with elevated liver enzyme levels, gallstone, PBC, chronic hepatitis B, and chronic hepatitis C. Because UDCA is administered at varied doses, it is important to know the appropriate dose and regimen for each condition. [ABSTRACT FROM AUTHOR]

Objective: Rare disease Background: Gallbladder anomalies are rare congenital defects with an incidence rate of approximately 2% in the general population. Phrygian cap gallbladder is a common anatomical variant in which the fundus of the gallbladder folds on itself. Gallstone impaction is rare, and it can be associated with acute pancreatitis. This report describes a 42-year-old woman with recurrent pancreatitis associated with gallstones and Phrygian cap gallbladder. Case Report: We report the case of a 42-year-old woman with acute biliary pancreatitis and a history of repeated hospitalizations for episodes of pancreatitis. A preoperative MRI was conducted, which revealed the presence of a Phrygian cap gallbladder that had not been previously reported in imaging studies. The patient underwent cholecystectomy surgery with a laparo-endoscopic approach (rendezvous technique). No intra-or postoperative complications occurred. Conclusions: We report a case of acute biliary pancreatitis caused by stone migration and describe the anatomical variant of the Phrygian cap gallbladder with its clinical implications. The literature contains very few reports of cholecystitis or pancreatitis in patients with a gallbladder anomaly. Continuous reporting of anatomical variations of the gallbladder and biliary tract improves clinical knowledge, and knowledge of gallbladder anomalies is crucial to avoid injury to the biliary tract during laparoscopic cholecystectomy. This case emphasizes the importance of accurate preoperative evaluation to prevent serious surgical complications. [ABSTRACT FROM AUTHOR]

Percutaneous endoscopy of the biliary system (cholangioscopy) and gallbladder (cholecystoscopy) has significantly impacted diagnostic and therapeutic approaches to many diseases in interventional radiology, overcoming previous challenges related to scope size and rigidity. The current endoscopes offer enhanced maneuverability within narrow tubular structures such as bile ducts. Before endoscopy, reliance on 2D imaging modalities limited real-time visualization during percutaneous procedures. Percutaneous endoscopy provides 3D perspectives, enabling a better appreciation of normal structures, targeted biopsy of lesions, and accurate deployment of therapeutic interventions. This review aims to explore percutaneous endoscopic findings across various biliary and gallbladder pathologies. [ABSTRACT FROM AUTHOR]

Objective: The aim of this study was to determine the characteristics of patients who required conversion from laparoscopic to open cholecystectomy. In addition, we compared the health outcomes of laparoscopic and converted cholecystectomy. Methods: This was a retrospective, cross-sectional study. The laparoscopic cholecystectomy procedures performed in hospitals of the Turkish Ministry of Health in 2016 were examined. Chi-square and Mann-Whitney U tests were used to analyze the data. Results: There were 103,387 laparoscopic cholecystectomy. Of these, 102,294 (98.9%) were laparoscopically completed, whereas 1,093 (1.1%) were converted to open cholecystectomy. The majority (75.9%) of the patients were female. The rate of conversion from laparoscopic to open cholecystectomy; in men ≥65 years of age, patients with chronic renal failure, hypertension, diabetes, malign neoplasm, and cerebrovascular disease were found to be statistically significantly higher than those in the opposing groups. Mortality, complications, intensive care unit treatment rates, and average hospitalization time were found to be statistically significant in cholecystectomy converted to open surgery. Conclusion: Patients who had converted cholecystectomy had more negative health outcomes than those who had completed the procedure laparoscopically. Old age, being male, and having comorbidities and malignancies increase the risk of conversion to open cholecystectomy. These factors can help determine the conversion risk of laparoscopic cholecystectomy to an open procedure. [ABSTRACT FROM AUTHOR]

Objective: Ceftriaxone and metronidazole (CEF/MET) combination therapy is commonly used in the empirical therapy of intra-abdominal infections (IAIs). We aimed to evaluate the treatment response in patients started on empirical CEF/MET therapy and contribute current treatment data on IAIs. Methods: A retrospective analysis was conducted on patients receiving parenteral antibiotic therapy in the general surgery department between 2016 and 2018. Patients aged 18 and older who received CEF/MET therapy for more than 24 hours with a diagnosis of IAI were included. Patient characteristics, antibiotic use and/or surgical history in the last three months, infection source, need for surgical intervention, and clinical and laboratory data were evaluated. Treatment response was analyzed in groups of patients with or without treatment changes. Results: 10,649 patients were evaluated; 591 (5.5%) received CEF/MET therapy, and 297 (50.2%) met the study criteria. Among them, 243 (81.8%) received only CEF/MET treatment (Group 1), while 54(18.2%) received additional antibiotics (median day 5) (Group 2). There was a statistically significant correlation between malignancy, antibiotic use in the last three months and history of surgical intervention and treatment change (p=0.001). The gallbladder (63%) or the biliopancreatic tract (12.1%) were the infection foci in 75.1% of all patients. Treatment was modified in 9.6% of the patients with an infection focused on the gallbladder and 55.6% of the patients with an infection focused on the biliopancreatic tract (p=0.001). Patients with treatment modification had more extended hospital stays and higher mortality rates (p=0.001). Conclusion: Empirical CEF/MET initiation is appropriate for IAIs with a gallbladder focus, yielding a favourable response in four out of five patients. However, CEF/MET therapy may be insufficient in patients with a biliopancreatic tract focus, a history of antibiotic use, malignancy, or surgical intervention, despite source control. Therefore, learning the source of infection and patient characteristics will contribute to the determination of the antibiotic to be selected in empirical treatment, increase treatment success, shorten the hospitalization period, and reduce mortality.

Aims: The aims of this study were to update risk estimates of obesity related co-morbidities and to provide evidence of the importance of obesity prevention to decision makers. Methods: The study included 25- to 74-year-old participants (N =22,977) of the National FINRISK Studies in 1997, 2002 and 2007. Body mass index was calculated from measured weight and height at baseline. Data on morbidity were ascertained via linkage to the National Hospital Discharge Register, the Cancer Register and the records of the Social Insurance Institution of Finland until the end of year 2018. The Cox proportional hazards model was used to estimate associations between weight status and the risk of the end-point diseases during follow-up, with adjustment for age and smoking. Results: At baseline, 31% of participants had at least one of the investigated diseases. Overweight, obesity and severe obesity were associated with type 2 diabetes, gout, gallbladder diseases and knee and hip osteoarthritis during the follow-up in both men and women. The risk of coronary heart disease was increased in men who were overweight, obese and severely obese and in women who were obese and severely obese. Risk of asthma was increased only among women who were obese and severely obese. No associations were found between obesity and breast, prostate or colorectal cancer. Conclusions: The study showed a strong relationship between excess body weight and the prevalence and incidence of several diseases. Obesity prevention is essential to reduce disease burden in the future. [ABSTRACT FROM AUTHOR]

Background: Gallstone disease, traditionally associated with older, overweight females, is increasingly being observed in younger individuals. This shift necessitates a closer examination of the unique characteristics and risk factors associated with gallstone development in this demographic. While conventional risk factors such as gender, age, and genetic predispositions continue to play a role, emerging trends suggest that modifiable factors, including dietary habits, lifestyle choices, and medical conditions, are also influential. Methods: In this observational study conducted at Al Wahda Teaching Hospital in Derna, Libya, between January 2021 and January 2022, we retrospectively collected data from 182 patients diagnosed with gallbladder disease. The study focused on recording demographic information and assessing modifiable risk factors, including dietary habits, reproductive history, smoking, and associated chronic illnesses. Results: The majority of patients were female (92.3%), with the most commonly affected age group being 26 - 30 years. The average weight of the population was also notably high. Assessment of modifiable risk factors revealed a high prevalence of a high-fat diet (75.8%) and a sedentary lifestyle (73.6%), while surprisingly, 69.2% maintained a high-fiber diet. A range of chronic illnesses contributed to a small proportion of cases, including hemolytic anemia (13.2%), diabetes mellitus (5.5%), and liver disease (4.4%). The predominance of laparoscopic cholecystectomy (54.9%) indicates a shift in treatment approach. Complications were absent in the majority of cases (81.3%), suggesting a generally favorable outcome in gallstone disease management within this cohort. Conclusions: The evolving nature of gallstone disease in younger populations calls for a reassessment of understanding and management strategies. The observed trends highlight the need for further research to better understand the changing landscape of gallstone disease and to develop targeted preventive measures for this demographic.

Schistosomiasis is an infectious disease caused by parasitic flatworms of the genus Schistosoma. The species Schistosoma mansoni is associated with hepatosplenic disease. Schistosomiasis involving the gallbladder alone is highly unusual, with a few cases reported. Herein, we present the case of a woman from a region with endemic schistosomiasis who presented with a painless solid lesion and wall thickening of the gallbladder. She underwent an uneventful laparoscopic cholecystectomy. Microscopic examination of the surgical specimen revealed Schistosoma mansoni eggs associated with granulomatous reaction, leading to the diagnosis of schistosomiasis of the gallbladder, prompting subsequent treatment with praziquantel and follow-up. This case illustrates the importance of suspicion for this diagnosis in endemic areas, as it can be misdiagnosed with malignancy if not examined microscopically. Complications and treatment strategies are poorly characterized for the few cases of schistosomiasis; reporting this case can serve as a helpful reminder of a rare presentation of this disease.

Gallbladder (GB) neoplasms, although rare, are the most common group of malignant neoplasms of the biliary system and can be missed preoperatively as well as on gross examination. Detection of the type of GB neoplasm and reporting the depth of invasion are important for appropriate management. Histopathologic examination of all cholecystectomy specimens is a must, even if no malignancy is detected radiologically or grossly. We describe a series of eight incidentally detected GB neoplasms and discuss the morphological features, staging, and management along with clinical significance. [ABSTRACT FROM AUTHOR]

Background. Gallbladder diseases are relatively common, most of which are asymptomatic, others may be presented with right hypochondriac pain. Obesity, metabolic syndrome, long-term fasting, rapid weight reduction, bariatric surgery and drugs are associated with bile stasis and hence participate in gallstone formation. The study aimed to determine the variety of gallbladder disease detected by ultrasound in Iraqi patients. Methods. This study involved a randomly selected sample of 100 men and 100 women who attended the ultrasound clinic at Emamein Kadhimein Medical City for abdominal ultrasonography for various reasons in a period of 8 months (Oct 2022-Jul 2023). Data about age, sex, risk factors and symptoms were collected from those who had ultrasound features of gallbladder diseases. Results. It was found that gallbladder diseases are more common in women (23% of all examined women) than men (11% of all examined men). The most affected age groups are between 40-49, the percentage of women affected in this age group is 30.47% and men 12%. Most of the cases were without symptoms. The most common ultrasound finding is gallstones, where the percentage of affected women reached 82.6% and the affected men 81.8%. Conclusion. Ultrasound has a valuable role in screening, detection and follows up of gallbladder diseases. It is safe, available and cost-effective examination. Gallbladder diseases particularly gall stones are relatively common in Iraqi population, being more common in middle age women with clear association with obesity and multiparty among other risk factors. Most of patients were asymptomatic others presented with symptoms like abdominal pain. [ABSTRACT FROM AUTHOR]

Laparoscopic cholecystectomy for benign gallbladder diseases is being practised as a day-care procedure in many centres around the world. This has been justified in view of the low rate of adverse events or complications following the surgery. There is a lack of uniform protocol for hospital admission and duration of hospital stay for elective laparoscopic cholecystectomy especially in developing countries in remote areas. The purpose of this study was to find out the possibility whether it was safe and feasible to discharge elective laparoscopic cholecystectomy patients as day-care (6 h) in a centre like ours where there is no dedicated unit for ambulatory surgery. It is a retrospective analysis of prospectively collected data. The study was conducted in the Department of general surgery in a rural healthcare setup. The suitability for discharge was assessed at 6 h after surgery. All patients were re-evaluated the following morning to rule out any negative outcomes that might have resulted from being released from the hospital at 6 h post-surgery. Total of 145 patients underwent elective laparoscopic cholecystectomy during the said period. The mean age is 39.6 years. Out of 145, 125 (86%) patients were dischargeable according to the modified Alderete score at 6 h. Duration of surgery (p-value-0.001), occurrence of postoperative nausea and vomiting (p-value-.002), critical view of safety visibility (p-value-.03) and need for foley's catheterization (p < 0.001) have significant associations with suitability for discharge at 6 h. Elective laparoscopic cholecystectomy surgery as a day-care procedure has its own advantages. According to the modified Alderete score, most of the patients in our study who were eligible for discharge after six hours did not experience any difficulties while they were hospitalised, making them candidates for same-day discharge. However, case selection should take care of patient and logistic factors. [ABSTRACT FROM AUTHOR]

Gallbladder diseases are very common, and their diagnosis is based on clinical–laboratory evaluation and imaging techniques. Considering the different imaging diagnostic tools, ultrasound (US) has the advantage of high accuracy combined with easy availability. Therefore, when a gallbladder disease is suspected, US can readily assist the clinician in the medical office or the emergency department. The high performance of US in the diagnosis of gallbladder diseases is mainly related to its anatomic location. The most frequent gallbladder pathological condition is gallstones disease, easily diagnosed via US examination. Acute cholecystitis (AC), a possible complication of gallstone disease, can be readily recognized due to its specific sonographic features. Additionally, a number of benign, borderline or malignant gallbladder lesions may be detected via US evaluation. The combined use of standard B-mode US and additional sonographic techniques, such as contrast-enhanced ultrasonography (CEUS), may provide a more detailed study of gallbladder lesions. Multiparametric US (combination of multiple sonographic tools) can improve the diagnostic yield during gallbladder examination. [ABSTRACT FROM AUTHOR]

Gallbladder polyps (GBP) are solid lesions originating from the gallbladder mucosa and extending into the gallbladder lumen. Preoperative diagnosis of GBP can be easily performed via USG; however, which patients should be followed up and which patients should be operated on is still a matter of discussion. This study aimed to investigate the histopathologic results and indications for surgery in patients diagnosed with GBP in the preoperative period and to present our clinical experience in light of current literature. Patients diagnosed with GBP and who had surgery in our general surgery clinic between July 2019 and July 2023 were retrospectively reviewed. A total of 57 patients were included in the study. The medical records, laboratory results, imaging results, and pathology reports of the patients were examined. The mean age of the patients was 47.1±11.7 years (23-78 years). The male/female ratio was 1.3/1. Polyp diameter was above 10 mm in 61.4% of patients and below 10 mm in 38.6%. The indication for surgery was the presence of coexisting cholelithiasis in 35.1% of the cases, symptomatic polyps in 33.3%, and increased polyp diameter in 21.1%. In histopathologic evaluation, cholesterol polyp was the most frequently encountered polyp (40.4%). The follow-up and treatment of GBP is still controversial. The most important factors to be considered in the surgical treatment of SCP are the polyp being over 10 mm and being symptomatic. In follow-up patients, further detailed clinical examination should be performed if necessary, and other imaging modalities should be preferred along with USG. Furthermore, it is required to establish up-to-date international algorithms for the follow-up and treatment of GBP. [ABSTRACT FROM AUTHOR]

Artificial Intelligence (AI) allows computers to self-develop decision-making algorithms through huge data analysis. In medical investigations, using computers to automatically diagnose diseases is a promising area of research that could change healthcare strategies worldwide. However, it can be challenging to reproduce or/and compare various approaches due to the often-limited datasets comprising medical images. Since there is no open access dataset for the Gallbladder (GB) organ, we introduce, in this study, a large dataset that includes 10,692 GB Ultrasound Images (UI) acquired at high resolution from 1,782 individuals. These UI include many disease types related to the GB, and they are organized around nine important anatomical landmarks. The data in this collection can be used to train machine learning (ML) and deep learning (DL) models for computer-aided detection of GB diseases. It can also help academics conduct comparative studies and test out novel techniques for analyzing UI to explore the medical domain of GB diseases. The objective is then to help move medical imaging forward so that patients get better treatment.

BackgroundCurrent guidelines recommend that patients with choledocholithiasis undergo same-admission cholecystectomy. The compliance with this guideline is poor in elderly patients. We hypothesized that elderly patients treated with endoscopic retrograde cholangiopancreatography (ERCP) alone would have higher complication and readmission rates than the patients treated with cholecystectomy.MethodsThe Nationwide Readmissions Database was queried for all patients aged ≥65 years with admission for choledocholithiasis January to June 2016. The patients were divided based on index treatment received: (1) no intervention; (2) ERCP alone; or (3) cholecystectomy. Multivariate analyses identified predictors of cholecystectomy during index admission and of readmissions.ResultsA total of 16,121 patients with choledocholithiasis were admitted; 38.4% underwent cholecystectomy, 37.6% endoscopic retrograde cholangiopancreatography alone, and 24.0% no intervention. The patients not receiving a cholecystectomy were more likely to be older, female, have a higher Elixhauser score, do-not-resuscitate status, and at a teaching hospital (all P < .001). Emergency readmissions for recurrent biliary disease were lowest in patients undoing a cholecystectomy (2.2% vs 9.2% endoscopic retrograde cholangiopancreatography and 12.4% no intervention, P < .001), as were readmissions for complications (3.6% vs 5.5% and 7.8%, P < .001). Cholecystectomy reduced rates of readmissions for recurrent disease (odds ratio 0.168, P < .001), for complications (odds ratio 0.540, P < .001), and death during readmission (odds ratio 0.503, P = .007); endoscopic retrograde cholangiopancreatography alone reduced only rates of readmissions. Age was not a predictor of readmission or death.ConclusionIndex admission cholecystectomy is associated with a lower risk of readmission for biliary disease or complications, as well as death during readmission, in elderly patients. Age alone is not predictive of outcomes; surgical intervention should be guided by clinical condition, comorbidities, and patient preference.

Abstract Background The clinical management of patients experiencing recurrent abdominal pain resembling biliary-type, but with negative findings on conventional transabdominal ultrasound (TUS), poses a challenge. In recent years, endoscopic ultrasound (EUS) has emerged as a valuable tool for diagnosing gallbladder diseases. This study aims to assess the role of EUS in the evaluation of gallbladder and biliary system diseases specifically in patients with normal transabdominal ultrasonography results. Methods This study was a cross-sectional analytic study that enrolled 150 patients with any complaints related to the gallbladder and biliary system necessitating transabdominal ultrasound and endosonography in the period between February 2021 and December 2021. Results The mean age of the studied patients was 46.1 ± 10.3 years; 46.7% were males and 53.3% were females. The main complaint was right abdominal pain in 78.0%; meanwhile, 74.7% had a picture of obstructive jaundice. EUS revealed gallbladder wall thickening in 15 patients (10%), mud and/or small stones inside the gallbladder in 73 patients (48.7%), positive GB mass and/or polyp findings in 30 patients (20%), and biliary lesions such as duct strictures and/or dilatations were detected in 48 patients (32%), while transabdominal ultrasound was normal in all those patients. Conclusion Endoscopic ultrasound (EUS) proves to be a valuable diagnostic modality in patients experiencing biliary-type abdominal pain, despite normal transabdominal ultrasonography results. It not only aids in the accurate diagnosis of underlying conditions but also has the potential to impact the management plan for these patients.

Gallbladder torsion is a rare cause of acute surgical abdomen. Early recognition and surgical intervention are important for reducing complications and improving postoperative patient outcomes, but standard imaging and laboratory evaluation typically are indistinguishable from those of acute cholecystitis. This article describes a patient with gangrenous cholecystitis secondary to torsion and summarizes recommendations for evaluation and management. [ABSTRACT FROM AUTHOR]

Objective: Some studies have found that cholecystectomy may increase the risk of colorectal cancer (CRC), while others have reached inconsistent conclusions. We thus performed a systematic review and meta-analysis to assess the incidence rate of CRC after cholecystectomy for patients with gallstones or gallbladder diseases, and whether the geographical location of the patients affected the results. Methods: We systematically searched PubMed, Embase, and Cochrane for studies reporting changes in the incidence rate of CRC after cholecystectomy published before January 12, 2023. Our main endpoint was the occurrence of CRC. Data were extracted and pooled, and the relative risk (RR) and 95% confidence interval (CI) were calculated. We assessed pooled data using a random-effects model. Results: In total, 477 articles were identified, and 6 articles were eligible, including 7 studies that included 797,917 participants. Overall, the summarized research results showed that the risk of CRC was reduced in patients with gallbladder diseases who underwent cholecystectomy (RR: 0.80, 95% CI: 0.65 to 0.99, p = 0.040; I2 = 85.0%). In the subgroup analysis based on different geographical locations, cholecystectomy was not associated with the risk of CRC in the Western population (RR: 0.90, 95% CI: 0.65 to 1.25, p = 0.522; I2 = 86.5%), but there was a negative correlation between cholecystectomy and the risk of CRC (RR: 0.66, 95% CI: 0.60 to 0.73, p = 0.000) in the Chinese population. Conclusions: Our findings support that for patients with gallstones or gallbladder diseases, the incidence of CRC after cholecystectomy is lower than that of patients who do not undergo cholecystectomy.

Studies have suggested that adults with gallbladder disease have increased risk of type 2 diabetes. This prospective cohort study assessed the risk of type 2 diabetes in postmenopausal women with gallbladder disease. Data from women enrolled in the Women's Health Initiative from 1993 to 2005, aged 50-79 years (mean = 63.2; standard deviation, 7.2), were analyzed. Cox proportional hazards regression models were used to estimate the risk of type 2 diabetes associated with gallbladder disease. There were 8,896 new cases of type 2 diabetes after 1,025,486 person-years of follow-up. Gallbladder disease was significantly associated with type 2 diabetes (hazard ratio = 1.52; 95% confidence interval (CI): 1.38,1.67). The observed risk of type 2 diabetes in women with both gallbladder disease and central obesity was 37% higher than expected (relative excess risk due to interaction = 0.37, 95% CI: 0.11,0.63) on the additive scale. The hazard ratios for type 2 diabetes associated with gallbladder disease were 1.25 (95% CI: 1.19,1.32) and 1.48 (95% CI: 1.34,1.63) in women with and without central obesity, respectively, on the multiplicative scale. Results of this study support further studies to determine whether interventions in older women with gallbladder disease would reduce type 2 diabetes risk, especially among those with central obesity. Future research should examine the pathophysiological basis of the association between gallbladder disease and type 2 diabetes.

Background: Esketamine, recognized for its analgesic, sedative, and anti-inflammatory qualities, is integral in multimodal analgesia. However, the potential opioid-sparing effects of intravenous esketamine, along with its impact on inflammatory responses, and cognitive function during laparoscopic surgery, remain unexplored. Methods: In this study, 90 patients scheduled for laparoscopic cholecystectomy were equally randomized into three groups: a normal saline control group (NS), a low-dose esketamine group (LS) and a high-dose esketamine group (HS). Subsequently, we monitored several parameters: hemodynamics, levels of stress and inflammatory responses, intraoperative doses of sufentanil, remifentanil, and propofol, and 24-hour postoperative sufentanil requirements. We also evaluated alterations in cognitive function, perioperative indicators, and potential adverse reactions among the three groups. Results: Compared to their levels 5 minutes prior to anesthesia (T0) and 30 minutes post-operation (T4), the NS group exhibited a more significant decrease in Mean Arterial Pressure (MAP) and Heart Rate (HR) at various time intervals: 5 minutes after the skin incision (T1), 30 minutes post-incision (T2), and at the conclusion of the operation (T3), compared to the LS and HS groups(P < 0.05). Furthermore, the NS group exhibited a greater increase in levels of adrenaline (AD), noradrenaline (NE), endothelin (ET), C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α), and interleukin-6 (IL-6) at T1, T2, and T3, more so than the other two groups(P < 0.05). 24 hours after the surgery, patients in the LS group and HS group had significantly higher Montreal Cognitive Assessment (MoCA) scores than those in the NS group(P < 0.05). The LS and HS groups required lower doses of propofol, remifentanil, and sufentanil during surgery (P < 0.05), experienced shorter postoperative recovery times, and had lower incidences of nausea, vomiting, and respiratory depression compared to the NS group (P < 0.05). Conclusion: The administration of low-dose esketamine has been shown to be safe, effective, and dependable in the context of laparoscopic gallbladder surgery. It has the capacity to stabilize hemodynamic responses, ameliorate both stress and inflammatory reactions from surgery, and hastens anesthesia recovery. Furthermore, it fosters the restoration of postoperative cognitive function. Notably, when combined with nalbuphine, it exhibits opioid-sparing effects, reducing postoperative adverse outcomes. Trial registration: The trial is registered with the China Clinical Trials Registry Registration Number: ChiCTR2300067596. Retrospectively registered (date of registration: 12/01/2023).

Background: The clinical management of patients experiencing recurrent abdominal pain resembling biliary-type, but with negative findings on conventional transabdominal ultrasound (TUS), poses a challenge. In recent years, endoscopic ultrasound (EUS) has emerged as a valuable tool for diagnosing gallbladder diseases. This study aims to assess the role of EUS in the evaluation of gallbladder and biliary system diseases specifically in patients with normal transabdominal ultrasonography results. Methods: This study was a cross-sectional analytic study that enrolled 150 patients with any complaints related to the gallbladder and biliary system necessitating transabdominal ultrasound and endosonography in the period between February 2021 and December 2021. Results: The mean age of the studied patients was 46.1 ± 10.3 years; 46.7% were males and 53.3% were females. The main complaint was right abdominal pain in 78.0%; meanwhile, 74.7% had a picture of obstructive jaundice. EUS revealed gallbladder wall thickening in 15 patients (10%), mud and/or small stones inside the gallbladder in 73 patients (48.7%), positive GB mass and/or polyp findings in 30 patients (20%), and biliary lesions such as duct strictures and/or dilatations were detected in 48 patients (32%), while transabdominal ultrasound was normal in all those patients. Conclusion: Endoscopic ultrasound (EUS) proves to be a valuable diagnostic modality in patients experiencing biliary-type abdominal pain, despite normal transabdominal ultrasonography results. It not only aids in the accurate diagnosis of underlying conditions but also has the potential to impact the management plan for these patients. [ABSTRACT FROM AUTHOR]

Bilobed or duplicate gallbladders are the rare anomalies of the biliary system occurring between the 5th and 6th weeks of embryonic life, of which Type 2 ductular variant is the commonest. Patients may be asymptomatic or symptomatic, with majority of the cases being detected intraoperatively or during re-operation. Once suspected a detailed preoperative evaluation is a must to avoid both intraoperative and postoperative complications. We report a case of a 34-year-old female who presented with acute onset of abdominal pain and was detected with symptomatic bilobed gallbladder (H Type) with cholelithiasis, with a resolution of symptoms after a successful laparoscopic cholecystectomy. The case emphasizes the importance of detailed preoperative evaluation in the form of ultrasound and magnetic resonance cholangiopancreatography to be considered during the management of biliary pathologies to avoid any intra- and post-operative complications.

BackgroundEarly experience with indocyanine green-based fluorescent cholangiography during laparoscopic cholecystectomy suggests the potential to improve outcomes. However, the cost-effectiveness of routine use has not been studied. Our objective was to evaluate the cost-effectiveness of fluorescent cholangiography versus standard bright light laparoscopic cholecystectomy for noncancerous gallbladder disease.MethodsA Markov model decision analysis was performed comparing fluorescent cholangiography versus standard bright light laparoscopic cholecystectomy alone. Probabilities of outcomes, survival, toxicities, quality-adjusted life-years, and associated costs were determined from literature review and pooled analysis of currently available studies on fluorescent cholangiography (n = 37). Uncertainty in the model parameters was evaluated with 1-way and probabilistic sensitivity analyses, varying parameters up to 40% of their means. Cost-effectiveness was measured with an incremental cost-effectiveness ratio expressed as the dollar amount per quality-adjusted life-year.ResultsThe model predicted that fluorescent cholangiography reduces lifetime costs by $1,235 per patient and improves effectiveness by 0.09 quality-adjusted life-years compared to standard bright light laparoscopic cholecystectomy. Reduced costs were due to a decreased operative duration (21.20 minutes, P < .0001) and rate of conversion to open (1.62% vs 6.70%, P < .0001) associated with fluorescent cholangiography. The model was not influenced by the rate of bile duct injury. Probabilistic sensitivity analysis found that fluorescent cholangiography was both more effective and less costly in 98.83% of model iterations at a willingness-to-pay threshold of $100,000/quality-adjusted life year.ConclusionThe current evidence favors routine use of fluorescent cholangiography during laparoscopic cholecystectomy as a cost-effective surgical strategy. Our model predicts that fluorescent cholangiography reduces costs while improving health outcomes, suggesting fluorescence imaging may be considered standard surgical management for noncancerous gallbladder disease. Further study with prospective trials should be considered to verify findings of this predictive model.
