A therapeutic ERCP in an only 5.9 kg infant with obstruction jaundice using JF-260V duodenoscope.

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) has found extensive use in pediatric patients; however, challenges persist in the application of therapeutic ERCP in infants. CASE PRESENTATION: This case report details the presentation of a 5.9-kilogram infant with obstructive jaundice and suspected hemolytic anemia who underwent ERCP to alleviate biliary obstruction. The infant was admitted due to clay-colored stools, jaundice, and liver injury. Ultrasound and magnetic resonance cholangiopancreatography (MRCP) revealed dilation of the common bile duct (CBD) accompanied by the presence of stones. ERCP was conducted using a JF-260V duodenoscope under general anesthesia. Successful stone extraction and biliary drainage were achieved. CONCLUSIONS: In centers with considerable expertise in ERCP and pediatric anesthesia, the use of a conventional adult duodenoscope for therapeutic ERCP in infants can be considered safe and feasible, provided careful and stringent patient selection criteria are applied. In the future, clear guidelines and standardized protocols for the indications and procedures of pediatric ERCP should be established.

Preoperative endoscopic ultrasound-guided biliary drainage for primary drainage in obstructive jaundice.

INTRODUCTION: Endoscopic transpapillary approach by endoscopic retrograde cholangiopancreatography (ERCP) is the established technique for preoperative biliary drainage (PBD). Recently, endoscopic ultrasound-guided biliary drainage (EUS-BD) has been reported to be a useful alternative technique after ERCP fail. However, the optimal strategy remain controversial. AREA COVERED: This review summarizes the literature on EUS-BD techniques for PBD with a literature search using PubMed, Web of Science, and the Cochrane Central Register of Controlled Trials database between 2000 and 2023 using keywords for 'preoperative biliary drainage' and all types of EUS-BD techniques. EXPERT OPINION: As there is no consensus on the optimal EUS-BD technique for PBD, selection of the EUS-BD approach depends on the patient's condition, the biliary obstruction site, the anastomosis after surgical intervention, and the preference of the endoscopist. However, we consider that EUS-HGS using a dedicated plastic stent may have some advantages in the adverse impact of surgical procedure because the location where the fistula is created by EUS-HGS is away from the site of the surgical procedure. Although there remain many issues that require further investigation, EUS-BD can be a feasible and safe alternative method of PBD for malignant biliary obstruction after ERCP fail.

Obstructive jaundice as a rare complication of multiple pancreaticoduodenal artery aneurysms due to median arcuate ligament syndrome: a case report and review of the literature.

BACKGROUND: Obstructive jaundice has various causes, and one of the rarest is pancreaticoduodenal artery aneurysm (PDAA), which is often associated with celiac axis stenosis caused by median arcuate ligament syndrome (MALS). CASE PRESENTATION: The patient was a 77-year-old Azeri woman who presented with progressive jaundice, vague abdominal pain, and abdominal distension from 6 months ago. The intra- and extrahepatic bile ducts were dilated, the liver's margin was slightly irregular, and the echogenicity of the liver was mildly heterogeneous in the initial ultrasound exam. A huge cystic mass with peripheral calcification and compressive effect on the common bile duct (CBD) was also seen near the pancreatic head, which was connected to the superior mesenteric artery (SMA) and had internal turbulent blood flow on color Doppler ultrasound. According to the computed tomography angiography (CTA) findings, the huge mass of the pancreatic head was diagnosed as a true aneurysm of the pancreaticoduodenal artery caused by MALS. Two similar smaller aneurysms were also present at the huge aneurysm's superior margin. Due to impending rupture signs in the huge aneurysm, the severe compression effect of this aneurysm on CBD, and the patient's family will surgery was chosen for the patient to resect the aneurysms, but unfortunately, the patient died on the first day after the operation due to hemorrhagic shock. CONCLUSION: In unexpected obstructive jaundice due to a mass with vascular origin in the head of the pancreas, PDAA should be considered, and celiac trunk should be evaluated because the main reason for PDAA is celiac trunk stenosis or occlusion by atherosclerosis or MALS. The treatment method chosen (including transarterial embolization, open surgery, or combined method) depends on the patient's clinical status and radiological findings, but transarterial embolization would be safer and should be used as a first-line method.

Significance of Shear Wave Dispersion Slope Values Before Versus After Biliary Drainage in Patients With Obstructive Jaundice: A Single-Center Prospective Observational Cohort Study.

ABSTRACT: The shear wave dispersion (SWD) slope has become available in the clinical practice and is related to tissue viscosity. However, clinical evaluation using SWD was not yet performed for obstructive jaundice. We aimed to evaluate the change of SWD values between before and after biliary drainage in patients with obstructive jaundice. This prospective observational cohort study evaluated 20 patients with obstructive jaundice who underwent biliary drainage. The SWD and liver elasticity values were measured before versus after biliary drainage, comparing between days -5 and 0 (day 0), days 1 and 3 (day 2), and days 6 and 8 (day 7). The mean ± SD values of SWD measured at day 0, day 2, and day 7 were 15.3 ± 2.7, 14.2 ± 3.3, and 13.3 ± 2.4 m/s/kHz, respectively. Dispersion slope values were decreased significantly from day 0 to day 2, from day 2 to day 7, and from day 0 to day 7 ( P < 0.05). Liver elasticity levels and serum hepatobiliary enzymes were additionally decreased significantly over time after biliary drainage. The correlations between SWD and liver elasticity values were strong ( r = 0.91, P < 0.01). In conclusion, t he SWD values decreased significantly over time after biliary drainage concomitant with liver elasticity.

Effect of Biliary Tract Invasion with Obstructive Jaundice on the Prognosis of Patients With Unresectable Hepatocellular Carcinoma.

RATIONALE AND OBJECTIVES: Biliary tract invasion (BTI) is associated with poor outcomes in patients with hepatocellular carcinoma (HCC). However, the presence of a BTI is a neglected variable for staging in the current guidelines. This study aimed to explore the effects of BTI with obstructive jaundice on the prognosis of patients with unresectable HCC. METHODS: We retrospectively included 205 patients initially diagnosed with unresectable HCC who presented with obstructive jaundice due to BTI between January 2010 and June 2021. BTI was classified into four types according to the location of the biliary obstruction. Both clinical and treatment factors that affect median overall survival (mOS) were analyzed. RESULTS: The mOS of patients with Barcelona Clinic Liver Cancer (BCLC) stages B, C, and D was 9.2 months, 3.4 months, and 1.8 months, respectively (p<.001). The mOS of BTI type I patients was superior to that of BTI type II patients (7.1 months vs. 3.2 months, p=.002). Patients who underwent successful biliary drainage had a longer mOS than those who underwent unsuccessful biliary drainage (10.4 months vs. 2.9 months, p<.001). In the multivariate analysis, BTI type I (p=.009), successful biliary drainage (p=.005), and HCC treatment (p<.001) were significant favorable prognostic factors that affected patient survival. CONCLUSION: HCC patients with BTI type II may have a poorer prognosis than those with BTI type I. Effective biliary drainage and anti-cancer treatment may provide survival benefits to these patients. A more detailed staging system for HCC based on the state of BTI is needed.

The value of endoscopic ultrasonography for differential diagnosis in obstructive jaundice of the distal common bile duct.

INTRODUCTION: Obstructive jaundice is a common clinical disease of great significance; however, diagnosing it according to etiology, especially in patients with distal obstructive jaundice is difficult. The development of endoscopic ultrasonography has improved diagnostic methods. Endoscopic ultrasonography not only improves the accuracy of conventional endoscopic ultrasound technology in etiological diagnosis, but also offers several special endoscopic ultrasound technologies for diagnosing distal obstructive jaundice of the common bile duct. What's more, endoscopic ultrasonography can be used to treat distal obstructive jaundice of common bile duct. AREAS COVERED: This review discusses the diagnostic value and applications of endoscopic ultrasonography for obstructive jaundice of the distal common bile duct. EXPERT OPINION: This article summarizes the value of endoscopic ultrasonography in the etiological diagnosis, relevant treatment applications of distal obstructive jaundice and the limitations of endoscopic ultrasonography in some etiologies due to the lack of clear comparison with other imaging methods. We also provide new data for the future research direction of endoscopic ultrasonography in distal obstructive jaundice.

A case of cholestasis caused by inferior vena cava filter.

Cholestasis and obstructive jaundice can be caused by several factors. Kuraoka et al. report an extremely rare case of cholestasis due to occlusion of the distal bile duct by an inferior vena cava filter, which was confirmed on imaging. Jaundice improved after placement of a biliary stent.

Magnetic Resonance Cholangiopancreatography to Evaluate Improvement Effect of FXR Regulating Bile Acid on Hepatocellular Carcinoma with Obstructive Jaundice.

This research aimed at exploring the improvement effect of Farnesoid X receptor (FXR) regulating bile acid (BA) on hepatocellular carcinoma with obstructive jaundice under magnetic resonance cholangiopancreatography (MRCP). Forty-eight hepatocellular carcinoma patients with obstructive jaundice who were examined in hospital were selected as the study group, and another 10 healthy volunteers who were examined at the same period were selected as the control group. The patients were treated with FXR inhibitor, and the therapeutic effect was observed. The results showed that after treatment, the AST content and TBIL content in serum of the study group were 123.5 ± 4.9 U/L and 1.8 ± 0.3 µmol/L, respectively, which were significantly lower than those before treatment, P < 0.05; the ALT content and AST content in serum in patients with high obstruction were significantly lower than those before treatment, and the K+ content was significantly higher than that before treatment (P < 0.05). The ALT, AST, and TBIL contents in serum in patients with low obstruction were significantly lower than those before treatment (P < 0.05). Apparent diffusion coefficient (ADC) was 1.17 ± 0.49 × 10-3 mm2/s in patients with moderate jaundice and 1.20 ± 0.27 × 10-3 mm2/s in patients with severe jaundice, compared with that before treatment, and the difference was statistically significant (P < 0.05). Based on FXR, it can regulate BA synthesis and metabolism, restore BA metabolic homeostasis, effectively play a hepatoprotective role, reduce bilirubin content in the body, and improve jaundice injury, which has application value.

[A case of obstructive jaundice due to the movement of pancreatic calculi].

A 44-year-old man with a history of chronic alcoholic pancreatitis and Crohn's disease presented with abdominal pain. Computed tomography revealed pancreatic calculi in the head of the pancreas and a dilated pancreatic duct. The patient was diagnosed with an acute exacerbation of chronic pancreatitis due to the impact of pancreatic calculi on the main pancreatic duct. During the clinical course, the movement of pancreatic calculi to the major papilla was confirmed, leading to obstructive jaundice. Endoscopic treatment with sphincterotomy of the pancreatic duct was successful. Herein, we report the case of an unusual clinical course involving obstructive jaundice caused by the movement of pancreatic calculi.

ERCP and situs inversus.

An 85-year-old female with situs inversus totalis was admitted due to obstructive jaundice, secondary to multiple choledocholithiasis and distal biliary stenosis due to adenocarcinoma of the head of the pancreas, with duodenal infiltration and metastatic liver disease. An endoscopic retrograde cholangiopancreatography (ERCP) was attempted in the supine position but bile duct cannulation was not possible due to duodenal infiltration. Finally, a palliative biliary stent was placed percutaneously, with resolution of the jaundice.

Obstructive Jaundice Caused by a Large Intact Abdominal Aortic Aneurysm. Case Report and Literature Review.

BACKGROUND: Obstructive jaundice caused by abdominal aortic aneurysm (AAA) is an extremely rare clinical presentation. We present an 85-year-old male with a large intact AAA causing obstructive jaundice and review the relevant literature. METHODS AND RESULTS: The patient was referred to our hospital with jaundice and a palpable pulsatile abdominal mass. Computerized tomography (CT) angiogram and magnetic resonance cholangiopancreatography (MRCP) revealed an infrarenal AAA with maximal diameter of 8.5 cm compressing the pancreatic head and common bile duct, causing obstructive jaundice with elevated levels of total, and direct bilirubin. The patient was subjected to endovascular aneurysm repair (EVAR). Blood bilirubin gradually decreased to normal levels. No complications were reported during the immediate postoperative and at 3-month follow up period. Literature review suggests that our case is one of the largest intact AAAs which have been reported to cause biliary obstruction. CONCLUSIONS: AAAs causing secondary obstructive jaundice is an uncommon clinical presentation requiring high clinical suspicion during differential diagnosis, so that patients can receive proper and early diagnosis and treatment.

Role of Magnetic Resonance Cholangiopancreatography in the Evaluation of Obstructive Jaundice.

Background Magnetic Resonance Cholangiopancreatography is a reliable and highly sensitive imaging modality in the diagnosis of Obstructive jaundice. Objective To evaluate the diagnostic accuracy of Magnetic Resonance Cholangiopancreatography as compared to Endoscopic Retrograde Cholangiopancreatography. Method A prospective, analytical study was conducted in the Department of Radiodiagnosis and Imaging at Dhulikhel Hospital between October 2018 and December 2020. Altogether 100 patients of all ages with obstructive jaundice undergoing Magnetic Resonance Cholangiopancreatography and Endoscopic Retrograde Cholangiopancreatography were included. The causes of obstructive jaundice as identified by Magnetic Resonance Cholangiopancreatography were compared to that of Endoscopic Retrograde Cholangiopancreatography considering Endoscopic Retrograde Cholangiopancreatography as gold standard for the diagnosis. Result Magnetic Resonance Cholangiopancreatography revealed choledocholithiasis in 60 (60%) patients, benign stricture - 14(14%), malignant stricture-11(11%), periampullary carcinoma in 8(8%) and normal study in 4(4%) patients. Endoscopic Retrograde Cholangiopancreatography showed choledocholithiasis in 59(59%) patients, strictures (benign in 13%, malignant in 10%), ascariasis in 3(3%) and normal findings in 5(5%) patients. The sensitivity, specificity, positive predictive value and negative predictive value of Magnetic Resonance Cholangiopancreatography in detecting choledocholithiasis were 96.6%, 92.3%, 95%, and 95%. The same values for benign strictures were 92.3%, 97.7%, 85.7% and 98.9%, whereas those for malignant strictures were 90.9%, 98.8%, 90.9% and 98.8%. All values were 100% for peri-ampullary carcinoma and ascariasis. Hence, Magnetic Resonance Cholangiopancreatography showed good accuracy for detecting causes of obstructive jaundice (p < 0.05) as compared to Endoscopic Retrograde Cholangiopancreatography. Conclusion Magnetic Resonance Cholangiopancreatography is an accurate, non-invasive technique in evaluation of obstructive jaundice and offers similar diagnostic value compared to Endoscopic Retrograde Cholangiopancreatography.
