Beyond the Usual Suspects: A Pictorial Case Report of Lemmel Syndrome Emphasizing the Role of Multimodality Imaging.

Lemmel syndrome, characterized by biliary and pancreatic duct obstruction secondary to a periampullary duodenal diverticulum (PAD), remains a rare and often overlooked diagnosis. Although duodenal diverticula are found in approximately 23% of the population, only about 5% of these cases lead to complications such as obstructions. A new case of Lemmel syndrome is demonstrated in the article about a middle-aged woman with chronic epigastric pain and right upper abdominal quadrant initially misdiagnosed as cholelithiasis. The accuracy of diagnosis was made possible by multimodal imaging methods, such as ultrasound, magnetic resonance cholangiopancreatography (MRCP), and computed tomography (CT) with oral contrast when a diffuse common bile duct was compressed by a PAD. Additionally, it highlights the necessity of including Lemmel syndrome in cases where patients have dilated bile ducts without calculi or mass lesions while emphasizing advanced imaging techniques for the revelation of structural malformations that underlay these conditions. The endoscopic intervention was minimally invasive but effective in relieving symptoms through sphincterotomy followed by laparoscopic cholecystectomy and biliary stent placement, thus making a point of the need for multiple disciplinary approaches toward treatment rare phenomenon like this one. This case report not only sheds light on the diagnostic and therapeutic avenues for Lemmel syndrome but also serves as a valuable educational resource for healthcare professionals. It emphasizes the need for heightened clinical vigilance and the adept use of imaging modalities in cases of biliary obstruction with obscure etiology. By contributing to the growing knowledge of this rare condition, we aim to facilitate timely diagnosis and optimize patient outcomes.

Lateral Pancreaticojejunostomy in a Rare Case of Chronic Calcific Pancreatitis With Peripancreatic Pseudocyst in an 18-Year-Old Male: A Case Report.

Another name for the Puestow surgery is a lateral pancreaticojejunostomy. The primary pancreatic duct, which runs from the head to the tail of the organ, is opened, exposing the pancreas. In order to allow the pancreas to empty straight into the intestines, the opening of the pancreatic duct is subsequently joined to a tiny intestinal loop. For more than 50 years, this process has been used to effectively relieve pain caused by chronic pancreatitis. This technique has a very low mortality rate and a low rate of surgical complications, and a high success rate. The gradual fibrosis of the pancreas resulting in the loss of exocrine and endocrine function is known as chronic pancreatitis. Intense pain is the disease's most typical symptom. It is unclear what causes the discomfort in chronic pancreatitis. Nonetheless, a large number of these patients have dilated ducts that are made up of intervening structures and saccular dilations, a condition known as the "chain of lakes" phenomenon. Radiological investigations can be used for diagnosis in these patients. Lateral pancreaticojejunostomy is the most effective treatment option for these individuals. Preservation of endocrine and exocrine pancreatic function is another benefit of lateral pancreaticojejunostomy. With lateral pancreaticojejunostomy, chronic fibrocalcific pancreatitis that manifests as pancreatic ductal dilatation and persistent discomfort can be effectively treated. Excellent early outcomes have been observed in terms of pain alleviation as well as post-operative morbidity and mortality; however, the patient's overall outcome and long-term follow-up have not been as well defined.

Post-cholecystectomy Clip Migration: A Case Report.

Surgical clip migration into the common bile duct (CBD) with subsequent stone formation is an exceedingly rare complication following both laparoscopic and open cholecystectomy, with fewer than 100 cases reported in the literature. Herein, we present the case of a 78-year-old female who presented with abdominal pain and dark urine six years after an open cholecystectomy. Her abdominal ultrasonography revealed no abnormalities, with only mild derangements noted in liver function tests. However, computed tomography of the abdomen unveiled a single metallic surgical clip lodged within the CBD, surrounded by a bile stone, alongside another clip at the gallbladder fossa. The patient underwent endoscopic retrograde cholangiopancreatography (ERCP), during which the clip was successfully removed. The procedure has utilized SpyGlass cholangioscopy. While clip migration into the CBD remains a rare phenomenon, it should be considered in the differential diagnosis of patients presenting with obstructive jaundice or biliary colic post-cholecystectomy. Minimally invasive management by ERCP is the procedure of choice for migrated clips-related complications but surgical common bile duct exploration may be necessary. This case highlights the importance of vigilance and prompt intervention in managing post-cholecystectomy clip migration (PCCM) but potentially serious postoperative complications.

Trifoliate gallbladder: A rare congenital anomaly masquerading as acute cholecystitis.

Key Clinical Message: Triple gallbladder, an extremely rare congenital anomaly, can mimic more common biliary conditions. Accurate diagnosis through imaging and a multidisciplinary approach is essential for timely surgical management, preventing complications, and ensuring better patient outcomes. Abstract: The multiplication of the gallbladder is a congenital malformation with a rare incidence of 1 in 4000 patients, among which the trifoliate gallbladder, even rarer, is included. Gallbladder anomalies are typically discovered incidentally while investigating conditions like gallstones, sedimentation, gallbladder inflammation, or malignancy. The clinical presentation of trifoliate gallbladder disease varies, and it may require a variety of imaging modalities to obtain a preoperative diagnosis. Recommended therapeutics for this anomaly are open or laparoscopic cholecystectomy, depending on the patient's condition. Early diagnosis of gallbladder multiplications is vital to improve prognosis and mitigate the risk of complications like cholelithiasis, cholecystitis, metaplasia, and adenocarcinoma. In our case, we present a 30-year-old male with the diagnosis of acute cholecystitis with triple gallbladder. A confirmatory diagnosis was made with magnetic resonance cholangiopancreatography (MRCP). The patient responded well to the therapy given and was discharged for follow-up.

Clinical study on the necessity and feasibility of routine MRCP in patients with cholecystolithiasis before LC.

BACKGROUND: In the past quite a long time, intraoperative cholangiography(IOC)was necessary during laparoscopic cholecystectomy (LC). Now magnetic resonance cholangiopancreatography (MRCP) is the main method for diagnosing common bile duct stones (CBDS). Whether MRCP can replace IOC as routine examination before LC is still inconclusive. The aim of this study was to analyze the clinical data of patients undergoing LC for cholecystolithiasis, and to explore the necessity and feasibility of preoperative routine MRCP in patients with cholecystolithiasis. METHODS: According to whether MRCP was performed before operation, 184 patients undergoing LC for cholecystolithiasis in the Department of General Surgery, Beijing Shijitan Hospital, Capital Medical University from January 1, 2017 to December 31, 2018 were divided into non-MRCP group and MRCP group for this retrospective study. The results of preoperative laboratory test, abdominal ultrasound and MRCP, biliary related comorbidities, surgical complications, hospital stay and hospitalization expenses were compared between the two groups. RESULTS: Among the 184 patients, there were 83 patients in non-MRCP group and 101 patients in MRCP group. In MRCP group, the detection rates of cholecystolithiasis combined with CBDS and common bile duct dilatation by MRCP were higher than those by abdominal ultrasound (P < 0.05). The incidence of postoperative complications in non-MRCP group (8.43%) was significantly higher (P < 0.05) than that in MRCP group (0%). There was no significant difference in hospital stay (P > 0.05), but there was significant difference in hospitalization expenses (P < 0.05) between the two groups. According to the stratification of gallbladder stone patients with CBDS, hospital stay and hospitalization expenses were compared, and there was no significant difference between the two groups (P > 0.05). CONCLUSIONS: The preoperative MRCP can detect CBDS, cystic duct stones and anatomical variants of biliary tract that cannot be diagnosed by abdominal ultrasound, which is helpful to plan the surgical methods and reduce the surgical complications. From the perspective of health economics, routine MRCP in patients with cholecystolithiasis before LC does not increase hospitalization costs, and is necessary and feasible.

Multiple small bowel obstructions due to unusual formation of biliary phytobezoars following laparoscopic cholecystectomy in a sickler patient: A case report, an atypical surgical approach.

INTRODUCTION & IMPORTANCE: Bezoar formation in gastrointestinal tract is relatively a rare condition. A phytobezoar is the most common type of bezoar (Kement et al., 2012 [6]). Biliary phytobezoar is an extremely rare condition and is usually reported in patients had previous biliary procedures or in presence of bilioenteric fistula (Albogami et al., 2018; Kement et al., 2012; Kim et al., 2006 [2, 6, 7]). CASE PRESENTATION: 35-year-old female with sickle cell anemia (SCA). On 2003 she had gallstones (GS) and obstructive jaundice. She was treated at that time by endoscopic retrograde cholangiopancreatography (ERCP) and sphincterotomy with stent insertion, followed by laparoscopic cholecystectomy (LC). Two years afterwards she had open appendectomy for acute appendicitis. Six months afterward, she suffered several episodes of small bowel obstructions (SBO) for several years. Later, it was discovered due to unusual formation of primary gallstones and subsequent development of biliary phytobezoars accumulated in the terminal ileum causing SBO. CLINICAL DISCUSSION: We are presenting an extremely rare case who developed biliary phytobezoars formation in the absence of a bilioenteric fistula leading to multiple small bowel obstructions. The origin of the gallstones was primary type. The surgical approach was limited right hemicolectomy solved her problem completely until the date of this publication. CONCLUSION: The nature of the disease adding higher risk of morbidity. Management of sicklers with surgical conditions should be individualized. Sicklers with asymptomatic gallstones should have early LC before complications begin. Because anticipated complications carry significant morbidity. The advances in surgical technology and better awareness of the pathophysiology provided an improved and better outcome.

A Rare Case of Trifoliate Gallbladder in an Adult Male and Its Management: A Comprehensive Case Report and Literature Review.

Triple gallbladder, a rare congenital abnormality resulting from the incomplete regression of rudimentary bile ducts, often goes undetected until incidentally discovered during imaging studies. This report presents the case of a 38-year-old male with intermittent abdominal pain, food intolerance, and nausea. Physical examination findings included tenderness in the right hypochondrium and a positive Murphy's sign. Laboratory tests revealed leukocytosis and elevated liver enzymes, while abdominal ultrasound identified three fluid-filled sacs in the expected gallbladder fossa location, with one showing cholelithiasis and mild wall thickening in all three. Further evaluation via magnetic resonance cholangiopancreatography (MRCP) unveiled three incompletely separated tubular cystic structures draining into a solitary cystic duct, confirming the diagnosis as trifoliate gallbladder type 3. This case highlights the importance of considering rare entities like triple gallbladder in the differential diagnosis of biliary pathologies, necessitating a high index of suspicion and comprehensive imaging to ensure accurate diagnosis and appropriate management, as exemplified by successful laparoscopic cholecystectomy.

Previously Untreated Ulcerative Colitis With Newly Diagnosed Primary Sclerosing Cholangitis: A Case Report.

Primary sclerosing cholangitis (PSC) is a rare type of autoimmune hepatic disease with unknown pathophysiology, often a sequela of ulcerative colitis (UC). Liver transplant, though curative, is inaccessible to many patients due to stringent organ availability and barriers to sufficient insurance coverage. Low health literacy and low socioeconomic class can significantly limit healthcare access and thus worsen overall healthcare outcomes. Here, we present the case of an uninsured 49-year-old man with untreated UC who was diagnosed with PSC and subsequently became lost to follow-up. It is critical for providers to identify barriers to acquiring appropriate medical care, such as financial instability and low health literacy, when identifying and treating conditions like PSC. Moreover, more research should be performed to investigate alternative treatments for PSC.

Periampullary Diverticula Causing Recurrent Pancreatitis: A Case Report.

Acute p-ancreatitis (AP) is increasingly rising globally, especially among elderly populations. In many cases, AP can progress to chronic pancreatitis (CP) and cause damage to the pancreas. Common causes of AP include gallstones and alcoholic injury, but periampullary diverticula (PAD) have emerged as a complex etiology. PADs are rare bowel-filled outpouchings located near the main papilla or common bile duct (CBD). In this study, we present a 66-year-old female with recurrent pancreatitis that is caused by a PAD. Due to the paucity of information regarding the management of PADs, we hope this case highlights the need to advance treatment options in this area.

Gallstone Pancreatitis Post Laparoscopic Cholecystectomy: A Case Report.

Gallstone pancreatitis is uncommon after laparoscopic cholecystectomy with minimal cases reported in the literature. We report a case of a 38-year-old female who developed gallstone pancreatitis three weeks after laparoscopic cholecystectomy. The patient presented to the emergency department with a two-day history of severe right upper quadrant and epigastric pain radiating to her back with associated nausea and vomiting. The patient had elevated total bilirubin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and lipase. The patient's preoperative abdominal magnetic resonance imaging (MRI) and magnetic resonance cholangiopancreatography (MRCP), prior to her cholecystectomy, were negative for common bile duct stones. However, it is important to note that common bile duct stones are not always visible on ultrasound, MRI, and MRCP prior to cholecystectomy. In our patient, an endoscopic retrograde cholangiopancreatography (ERCP) revealed gallstones in the distal common bile duct, which were removed with biliary sphincterotomy. The patient had an uneventful postoperative recovery. It is important for physicians to have a high index of suspicion for gallstone pancreatitis in a patient with epigastric pain radiating to the back with a known history of recent cholecystectomy, as this is a diagnosis that can be missed due to its infrequent occurrence.

Investigation of the accuracy of magnetic resonance cholangiography and multi-slice spiral computed tomography in the diagnosis of cholangiocarcinoma.

Background: Cholangiocarcinoma (CCA) is a common malignant biliary tract tumor in clinical practice. The detection rate of multi-slice spiral computed tomography (MSCT) with a diameter of 10 mm is low, and it is easy to be misdiagnosed and missed. In addition, patients who are allergic to iodized contrast media are not eligible for MSCT screening. However, magnetic resonance cholangiopancreatography (MRCP) is non-invasive, does not require contrast injection, scans quickly, and is simple to perform. MRCP has good development rate and the ability to recognize human pancreas and biliary tract. MRCP is also non-invasive, does not require contrast injection, has fast scanning speed, and is easy to operate. In addition, MRCP has a good development rate and the ability to recognize human pancreas and biliary tract. Therefore, this study sought to analyze the accuracy of MRCP and MSCT in the diagnosis of CCA. Methods: In this paper, 186 patients with highly suspected CCA admitted to the Second Affiliated Hospital of Soochow University from March 2020 to May 2022 were selected for MSCT and MRCP examination. We compared the diagnostic accuracy, sensitivity and specificity of MSCT and MRCP with pathological diagnosis and the detection rate of lesions with different diameters between MSCT and MRCP. Finally, the imaging features of MSCT and MRCP of CCA were analyzed. Results: The results showed that (I) the diagnostic accuracy (95.70%), sensitivity (95.12%), and specificity (96.15%) of MRCP were higher than those of MSCT (69.89%, 60.98%, and 76.92%, respectively; P<0.05); (II) MSCT and MRCP were basically consistent with the datum (Kappa value =0.527, Kappa value =0.767, respectively); (III) the detection rate of lesions <0.5 cm in diameter of MRCP (32.05%) was higher than that of MSCT (14.00%; P<0.05); and (IV) the detection rates of lesions 0.5-1.0 cm (38.46%) and >1.0 cm (29.49%) in diameter of MRCP were lower those of MSCT (50.00%, and 36.00%, respectively; P>0.05). Conclusions: MRCP can provide relevant imaging feature information, improve the accuracy, sensitivity and specificity of the diagnosis of bile duct carcinoma, and has a high detection rate for small diameter lesions, which has good reference, promotion and reference value.

Case Series of MRI and CT Assessment of Acquired Hepato-Biliary and Pancreatic Transdiaphragmatic Fistulae.

Transdiaphragmatic fistulae are rare conditions characterized by pathological communication between two epithelium-lined surfaces. Hepato-thoracic fistula consists of abnormal communication between the liver and/or the biliary system and the thorax; while the pancreaticopleural fistula consists of abnormal communication between the pancreas and the thorax, the pleuro-biliary fistula represents the more common type. Clinical symptoms and laboratory findings are generally non-specific (e.g., thoracic and abdominal pain, dyspnea, cough, neutrophilia, elevated CPR, and bilirubin values) and initially, first-level investigations, such as chest RX and abdominal ultrasound, are generally inconclusive for the diagnosis. Contrast-enhanced CT represents the first two-level radiological imaging technique, usually performed to identify and evaluate the underlying pathology sustained by transdiaphragmatic fistulae, their complications, and the evaluation of the fistulous tract. When the CT remains inconclusive, other techniques such as MRI and MRCP can be performed. A prompt and accurate diagnosis is crucial because the recognition of fistulae and the precise definition of the fistulous tract have a major impact on the management acquisition process.

Pancreatic Cystic Lesions: Imaging Techniques and Diagnostic Features.

The detection of incidental pancreatic cystic lesions has increased over time. It is crucial to separate benign from potentially malignant or malignant lesions to guide management and reduce morbidity and mortality. The key imaging features used to fully characterize cystic lesions are optimally assessed by contrast-enhanced magnetic resonance imaging/magnetic resonance cholangiopancreatography, with pancreas protocol computed tomography offering a complementary role. While some imaging features have high specificity for a particular diagnosis, overlapping imaging features between diagnoses may require further investigation with follow-up diagnostic imaging or tissue sampling.

Diagnostic Accuracy of Magnetic Resonance Cholangiopancreatography in Comparison With Endoscopic Retrograde Cholangiopancreatography for Detection of the Etiology of Obstructive Jaundice.

BACKGROUND: Despite technological advances, obstructive jaundice has significant morbidity and mortality rates. When studying obstructive jaundice, endoscopic retrograde cholangiopancreatography (ERCP), the "gold standard" for biliary obstruction identification, might be replaced with magnetic resonance cholangiopancreatography (MRCP), which is a non-invasive procedure. OBJECTIVE: Diagnostic accuracy of MRCP in comparison with ERCP for the detection of the etiology of obstructive jaundice. METHODOLOGY: This prospective, observational study included 102 patients who presented with obstructive jaundice as proven by liver function tests. The MRCP was conducted within 24 to 72 hours before the ERCP. A torso phased-array coil (Siemens, Germany) was used for the MRCP. The duodeno-videoscope and general electric fluoroscopy were used to perform the ERCP. The MRCP was evaluated by a classified radiologist who was blinded to the clinical details. An experienced consultant gastroenterologist who was blinded to the results of the MRCP assessed the cholangiogram of each patient. The hepato-pancreaticobiliary system results from both procedures were compared based on the pathology observed, such as choledocholithiasis, pancreaticobiliary strictures, and dilatation of biliary strictures. We determined the sensitivity, specificity, and negative and positive predictive values with 95% confidence intervals. The statistical significance was set at p<0.05. RESULTS: The most commonly reported pathology was choledocholithiasis, and MRCP diagnosed 55 patients, of which 53 were true positive cases when compared with the ERCP results of the same patients. MRCP demonstrated greater sensitivity and specificity (respectively) for screening choledocholithiasis (96.2, 91.8), cholelithiasis (100, 75.8), pancreatic duct stricture (100, 100), and hepatic duct mass (100, 100) and showed statistically significant values. The sensitivity of MRCP is lower for identifying benign and malignant strictures, but its specificity was observed to be reliable. CONCLUSION: When it comes to determining the severity of obstructive jaundice, both in its early and later stages, the MRCP technique is widely regarded as a reliable means of diagnostic imaging. The diagnostic function of ERCP has been significantly reduced as a result of the precision of MRCP as well as its non-invasive nature. In addition to being a helpful non-invasive method to identify biliary diseases and avoid unnecessary ERCPs and their risks, MRCP offers good diagnostic accuracy for obstructive jaundice.

Acute Gallstone Pancreatitis: If a Picture Is Worth a Thousand Words, How Many Images Do We Need?

Introduction Accurate diagnosis and prompt definitive management of choledocholithiasis are vital in acute gallstone pancreatitis. The sensitivity of detection of choledocholithiasis varies across imaging modalities. Magnetic resonance cholangiopancreatography (MRCP) is the most sensitive but may not be necessary, resulting in both delayed definitive management and increased costs. We aimed to evaluate the range of radiological investigations patients with acute gallstone pancreatitis underwent and the clinical appropriateness of MRCP when performed. Methods This was an observational study of patients diagnosed with acute gallstone pancreatitis between January 1, 2019 and November 30, 2021 in a district general hospital in London, UK. A detailed review of patient records, laboratory and radiological results, and endoscopic and/or operative intervention was undertaken. Results One hundred consecutive patients diagnosed with acute gallstone pancreatitis (median age 57 years) were included. Seventy-nine had a transabdominal ultrasound (USS), 46 had CT, and 40 patients had MRCP. The median waiting time for these investigations was 1, 0, and 4 days, respectively. Choledocholithiasis was identified in 21 patients (4 on USS, 5 on CT, and 12 on MRCP). As definitive management, 37% underwent endoscopic retrograde cholangiopancreatography, and 57% underwent laparoscopic cholecystectomy. A total of 19% of patients were readmitted with pancreatitis prior to definitive management. Conclusions First-line imaging investigations such as USS and CT can detect some cases of choledocholithiasis in patients with acute gallstone pancreatitis, but not all. Despite expenses in terms of cost and length of hospital stay, MRCP remains an essential resource to detect cases of choledocholithiasis not captured by USS or CT. We recommend establishing a guideline to streamline imaging in assessing acute gallstone pancreatitis.

Longitudinal changes in quantitative magnetic resonance imaging metrics in children and young adults with autoimmune liver disease.

PURPOSE: To assess longitudinal changes in quantitative MRI metrics in pediatric and young adult patients with autoimmune liver disease (AILD). METHODS: This prospective, IRB-approved study included 20 children and young adults (median age = 15 years) with primary sclerosing cholangitis (PSC)/autoimmune sclerosing cholangitis (ASC) and 19 (median age = 17 years) with autoimmune hepatitis (AIH). At a field strength of 1.5-T, T2*-corrected T1 mapping (cT1), 3D fast spin-echo MRCP, and 2D gradient recalled echo MR elastography (MRE) were performed at baseline, one year, and two years. cT1 and quantitative MRCP were processed using LiverMultiScan and MRCP + , respectively (Perspectum Ltd, Oxford, UK). Linear mixed models were used to assess longitudinal changes in quantitative MRI metrics. Spearman rank-order correlation was used to assess relationships between changes in quantitative MRI metrics. RESULTS: Changes in quantitative MRI metrics greater than established repeatability coefficients were measured in six (cT1) and five (MRE) patients with PSC/ASC as well as in six patients (cT1 and MRE) with AIH, although linear mixed models identified no significant changes for the subgroups as a whole. For PSC/ASC, there were positive correlations between change in liver stiffness and changes in bile duct strictures (ρ = 0.68; p = 0.005) and bile duct dilations (ρ = 0.70; p = 0.004) between baseline and Year 2. CONCLUSION: On average, there were no significant changes in quantitative MRI metrics over a two-year period in children and young adults with AILD. However, worsening cholangiopathy was associated with increasing liver stiffness by MRE in patients with PSC/ASC.

Application of SpyGlass endoscopic direct visualization system in complicated biliary complications after orthotopic liver transplantation / 器官移植

Objective To evaluate the application efficacy of SpyGlass endoscopic direct visualization system in management of complex biliary complications after orthotopic liver transplantation. Methods Clinical data of 369 adult patients with biliary complications after orthotopic liver transplantation who received endoscopic retrograde cholangiopancreatography (ERCP) for the first time were retrospectively analyzed. Preoperative conditions, intraoperative manifestations, treatment outcomes and complications of patients treated with SpyGlass system were analyzed. Results Fifty-six patients were treated with SpyGlass system. The main preoperative symptoms included abdominal discomfort in 38 cases, fever in 8 cases, jaundice in 6 cases and skin itching in 4 cases. Ultrasound examination in 18 patients indicated common bile duct stenosis and significant intrahepatic bile duct dilatation. Preoperative magnetic resonance cholangiopancreatography (MRCP) of 56 patients revealed that 36 cases were diagnosed with common bile duct stenosis complicated with stones, 16 cases of common bile duct stenosis alone and 4 cases of suspected tumors. All patients had definite indications for SpyGlass system treatment. Among 56 patients treated with SpyGlass system, 34 cases were diagnosed with anastomotic stricture complicated with stones, 12 cases of anastomotic stricture alone, 1 case of biliary stone and 4 cases of tumors. Among 48 cases who were successfully treated, the levels of alanine aminotransferase, aspartate aminotransferase, γ-glutamyltransferase, alkaline phosphatase and total bilirubin at postoperative 48 h were all significantly lower than preoperative levels (all P<0.05). No severe complications occurred in 56 patients treated with SpyGlass system. Conclusions Use of SpyGlass system may significantly increase success rate and guarantee surgical safety in the treatment of complex biliary complications after liver transplantation, which is worthy of promotion and application.

COVID-19 Vaccination-Induced Cholangiopathy and Autoimmune Hepatitis: A Series of Two Cases.

The coronavirus disease 2019 (COVID-19) pandemic has been associated with significant morbidity and mortality. Following the introduction of vaccines, various side effects have been reported. Whilst those reported may be attributed to the vaccine itself, at times, it may simply incite an immunological phenomenon. We present a case series of two patients who presented with symptoms of yellowing of the eyes and the skin along with fatigue, and tiredness, following vaccination for COVID-19. The diagnosis of post COVID-19-vaccination related hepatitis is one of the fewer, less understood, yet reported side effects associated with significant morbidity. The diagnosis of COVID-19 vaccination-related cholangitis is an outcome reported here for the first time to the best of our knowledge. It was alarming that both patients did not have any significant past history of medical ailments. A prompt assessment followed by investigations including liver biopsy assisted in a timely understanding of the phenomenon with complete resolution of the symptoms.

Bouveret's Syndrome: A Case Series and Literature Review on a Gallstone Disease Causing Gastric Outlet Obstruction.

Introduction Bouveret's syndrome refers to a gastric outlet obstruction due to the impaction of a large gallstone following retrograde migration via a bilio-duodenal fistula. Although no clear management guideline has been formulated, different treatment modalities have been described, including endoscopic stone removal using classical endoscopic devices, like snares and forceps, or fragmentation of stones with new devices, such as lasers and extracorporeal shockwave lithotripsy (ESWL). Results This case series reports six patients who have been diagnosed with Bouveret's syndrome and have presented with interesting radiological and endoscopic findings. The report is followed by a literature review, including diagnostic and management options for this rare condition. Discussion Cholelithiasis is a common condition occurring in the general population and may develop rare complications such as cholecystoduodenal fistula. Bouveret's syndrome presents with a clinical picture similar to that of gastric outlet obstruction, and laboratory findings are often consistent with an obstructive jaundice picture. The use of endoscopic treatment with a range of different lithotripsy modalities has been described to manage this condition. Conclusion The diagnosis of Bouveret's syndrome is made after performing appropriate imaging studies. The first-line management option is endoscopic treatment. If this fails, surgical intervention is recommended.

Oral effervescent agent improving magnetic resonance cholangiopancreatography.

Background: The purpose of our study was to validate the oral effervescent agent improving magnetic resonance cholangiopancreatography (MRCP) in patients with suspicious pancreatobiliary disease. Methods: One hundred and eleven consecutive patients with alleged or suspected pancreatobiliary tree problems who had undergone two-dimensional (2D) MRCP imaging both before and after oral effervescent enhancement (conventional-MRCP and enhanced-MRCP) were included. Two radiologists independently scored overall image quality, visualization of ten ductal segments, and gastroduodenal fluid signal intensity score. In consensus, they assessed the presence of gastroduodenal fluids and pancreatobiliary tree overlapping. The data were analyzed using Wilcoxon's signed-rank test, McNemar test, and paired t-test. Results: The grades of overall image quality and individual biliary duct visualization for ten targeted ductal segments, and gastroduodenal fluid signal intensity scores increased significantly on enhanced-MRCP by both readers (P≤0.02), but there was no significant increase for pancreatic duct (PD) at head and tail. On enhanced-MRCP, gastroduodenal fluids except for gastric fundus were less detected rather than those on conventional-MRCP. Anatomic structures of gastroduodenal fluids overlapping extrahepatic bile duct were mainly gastric antrum, duodenal bulb, and 2nd portion on conventional-MRCP. However, these fluids were less overlapped on enhanced-MRCP (P<0.001). Gastric body and antrum were main anatomic structures of gastroduodenal fluids overlapping PD on conventional-MRCP, and fluid in these locations significantly less overlapped PD on enhanced-MRCP (P≤0.02). Conclusions: Oral administration of effervescent agent provided effective elimination of gastroduodenal fluid overlapping pancreatobiliary ductal system at MRCP and can improve the quality of the examination in the patients with known or suspected pancreatobiliary disease.
