The Need for Standardizing Diagnosis, Treatment and Clinical Care of Cholecystitis and Biliary Colic in Gallbladder Disease

A Rare Case of Methamphetamine-Induced Diffuse Gastrointestinal Ischemia

Methamphetamine is a widely used substance known for cardiovascular and neurological complications; however, its gastrointestinal effects remain poorly understood. While rare, methamphetamine-induced gastrointestinal ischemia has high morbidity and mortality rates, with limited case reports in the literature. We present a case of a 48-year-old man with a history of gastroesophageal reflux disease, alcohol use disorder in remission, and previously documented methamphetamine use who presented with two weeks of episodic abdominal pain, nausea, and hematemesis. Significant laboratory and imaging findings included acute anemia, urine toxicology confirming the presence of amphetamines, and computed tomography imaging showing wall thickening in the distal esophagus and stomach. On endoscopy, he was found to have diffuse ulcerations in the distal esophagus and post-pyloric region with pathology indicative of methamphetamine-induced gastrointestinal ischemia. This case highlights the importance of considering amphetamine-induced gastrointestinal ischemia in patients with stimulant use disorders who present with acute abdominal symptoms. Early recognition of this etiology can guide targeted counseling and management to improve outcomes.

An Indian surgeon's perspective on management of asymptomatic gallstones

INTRODUCTION

Cholelithiasis is widely prevalent in India, with a majority of patients being asymptomatic while a small proportion experiencing mild complications. In the laparoscopic era, the rate of cholecystectomies has increased owing to early recovery and fewer complications. In asymptomatic patients, the risk of complications must be balanced against the treatment benefit. Recent guidelines suggest no prophylactic cholecystectomy in asymptomatic patients. We aimed to find out the Indian surgeons' perspective on asymptomatic gallstone management.

METHODS

A cross-sectional e-survey was conducted of practicing surgeons, onco-surgeons and gastrointestinal-surgeons in India. The survey had questions regarding their perspective on laparoscopic cholecystectomy and treatment modalities in asymptomatic gallstones.

RESULTS

A total of 196 surgeons responded to the survey. Their mean age was 42.3 years. Overall, 111 (57%) respondents worked in the private sector. Most surgeons (164) agreed that the rate of cholecystectomy has increased since the advent of laparoscopy; 137 (70%) respondents agreed that they would not operate on patients without risk factors. Common bile duct stones, chronic hemolytic diseases, transplant recipients, and diabetes mellitus were the risk factors. Majority of the participants agreed on not performing a cholecystectomy in patients with asymptomatic gallstones.

CONCLUSION

There exists a lack of consensus among Indian surgeons on asymptomatic gallstone management in India. Where the majority of cases are asymptomatic and do not require surgery, certain comorbidities can influence the line of treatment in individual patients. Currently, the treatment guidelines for asymptomatic patients need to be established as cholecystectomies may be overperformed due to the fear of development of complications.

Cholelithiasis management during hepatitis C treatment: a case report including pathophysiology and literature review

This case reports a 56-year-old male attending a nurse-led hepatitis C (HCV) clinic complaining of abdominal pain. Right upper quadrant abdominal tenderness on palpation with a positive Murphy's sign (pain on inspiration during palpation to the right subcostal area) encouraged timely investigation and diagnosis of non-obstructive cholelithiasis (gallstones). This was managed with interval review and regular clinical assessment pending successful HCV treatment and surgical referral. The main lessons from this case study emphasise the importance of considering concurrent diagnoses for patients complaining of abdominal pain when presenting with a primary diagnosis of HCV. This case also supports a pragmatic approach in considering the treatment of HCV before the surgical intervention of uncomplicated gallstones. Furthermore, it also highlights the value of advanced nurse practice within the multi-disciplinary team.

Not all cholecystitis is created equal: Disparities contributing to ED presentation and failure of the outpatient algorithm

BACKGROUND

The majority of final surgical pathology (FSP) from both emergency department (ED) and outpatient clinic (OC) patients is chronic cholecystitis. We aimed to differentiate these presentations and identify disparities associated with ED utilization and OC failure.

METHODS

Retrospective chart review of single institution ED and OC cholecystectomies for cholelithiasis. Clinical presentation, FSP, demographics, and zip code poverty (ZCP) levels were evaluated. Data analysis by summary statistics, bivariate comparisons, and logistic regression.

RESULTS

Of 299 OC and 308 ED patients, OC was more likely to be Caucasian (78% vs 46%, p < 0.0001) and insured (89% vs. 32%, p < 0.0001). 71.8% of OC with ZCP <10% had insurance versus only 32.5% in ZCP >20%. Uninsured ED OR was 13.1 (95% CI 8.7-22.9).

CONCLUSION

Uninsured ED patients are vulnerable to fail the outpatient algorithm, especially when misdiagnosed by US. Clinical diagnosis of cholecystitis in this population should warrant offering of urgent cholecystectomy.

Gallstone and Gallbladder Disease: Biliary Tract and Cholangiopathies

Cholestatic liver diseases are named primarily due to the blockage of bile flow and buildup of bile acids in the liver. Cholestasis can occur in cholangiopathies, fatty liver diseases, and during COVID-19 infection. Most literature evaluates damage occurring to the intrahepatic biliary tree during cholestasis; however, there may be associations between liver damage and gallbladder damage. Gallbladder damage can manifest as acute or chronic inflammation, perforation, polyps, cancer, and most commonly gallstones. Considering the gallbladder is an extension of the intrahepatic biliary network, and both tissues are lined by biliary epithelial cells that share common mechanisms and properties, it is worth further evaluation to understand the association between bile duct and gallbladder damage. In this comprehensive article, we discuss background information of the biliary tree and gallbladder, from function, damage, and therapeutic approaches. We then discuss published findings that identify gallbladder disorders in various liver diseases. Lastly, we provide the clinical aspect of gallbladder disorders in liver diseases and ways to enhance diagnostic and therapeutic approaches for congruent diagnosis. © 2023 American Physiological Society.

Detection of Gallbladder Disease Types Using Deep Learning: An Informative Medical Method

Nowadays, despite all the conducted research and the provided efforts in advancing the healthcare sector, there is a strong need to rapidly and efficiently diagnose various diseases. The complexity of some disease mechanisms on one side and the dramatic life-saving potential on the other side raise big challenges for the development of tools for the early detection and diagnosis of diseases. Deep learning (DL), an area of artificial intelligence (AI), can be an informative medical tomography method that can aid in the early diagnosis of gallbladder (GB) disease based on ultrasound images (UI). Many researchers considered the classification of only one disease of the GB. In this work, we successfully managed to apply a deep neural network (DNN)-based classification model to a rich built database in order to detect nine diseases at once and to determine the type of disease using UI. In the first step, we built a balanced database composed of 10,692 UI of the GB organ from 1782 patients. These images were carefully collected from three hospitals over roughly three years and then classified by professionals. In the second step, we preprocessed and enhanced the dataset images in order to achieve the segmentation step. Finally, we applied and then compared four DNN models to analyze and classify these images in order to detect nine GB disease types. All the models produced good results in detecting GB diseases; the best was the MobileNet model, with an accuracy of 98.35%.

Gallbladder cancer

Gallbladder cancer (GBC) is the most common cancer of the biliary tract, characterized by a very poor prognosis when diagnosed at advanced stages owing to its aggressive behaviour and limited therapeutic options. Early detection at a curable stage remains challenging because patients rarely exhibit symptoms; indeed, most GBCs are discovered incidentally following cholecystectomy for symptomatic gallbladder stones. Long-standing chronic inflammation is an important driver of GBC, regardless of the lithiasic or non-lithiasic origin. Advances in omics technologies have provided a deeper understanding of GBC pathogenesis, uncovering mechanisms associated with inflammation-driven tumour initiation and progression. Surgical resection is the only treatment with curative intent for GBC but very few cases are suitable for resection and most adjuvant therapy has a very low response rate. Several unmet clinical needs require to be addressed to improve GBC management, including discovery and validation of reliable biomarkers for screening, therapy selection and prognosis. Standardization of preneoplastic and neoplastic lesion nomenclature, as well as surgical specimen processing and sampling, now provides reproducible and comparable research data that provide a basis for identifying and implementing early detection strategies and improving drug discovery. Advances in the understanding of next-generation sequencing, multidisciplinary care for GBC, neoadjuvant and adjuvant strategies, and novel systemic therapies including chemotherapy and immunotherapies are gradually changing the treatment paradigm and prognosis of this recalcitrant cancer.
