Pylephlebitis-induced acute liver failure: A case report and review of literature.

BACKGROUND: Pylephlebitis is an extremely rare form of septic thrombophlebitis involving the portal vein, carrying high rates of morbidity and mortality. CASE SUMMARY: We present a case of a 42-year-old male with no past medical history who presented with acute onset of abdominal pain and altered mental status with laboratory tests demonstrating new-onset acute liver failure. Pylephlebitis was determined to be the underlying etiology due to subsequent workup revealing polymicrobial gram-negative anaerobic bacteremia and complete thrombosis of the main and left portal veins. To our knowledge, this is the first documented case of acute liver failure as a potential life-threatening complication of pylephlebitis. CONCLUSION: Our case highlights the importance of considering pylephlebitis in the broad differential for abdominal pain, especially if there are co-existing risk factors for hypercoagulability. We also demonstrate that fulminant hepatic failure in these patients can potentially be reversible with the immediate initiation of antibiotics and anticoagulation.

Primary Diffuse Large B-cell Lymphoma of the Colon Presenting as Idiopathic Thrombocytopenia: A Case Report.

Introduction: Primary lymphoma of the colon and rectum is an uncommon form of cancer comprising less than 0.5% of all colorectal tumors combined. Typically, extra nodal lymphomas manifest in the gastrointestinal tract, with non - Hodgkin lymphoma being the most frequent subtype and the stomach being the most common location. Case presentation: 70 year old female with medical history of osteoarthritis and osteoporosis was evaluated for bilateral leg rash and thrombocytopenia. Eventual work up revealed cecal mass but inconclusive findings on colonoscopy. She underwent hemicolectomy due to persistent thrombocytopenia with histopathology positive for primary Diffuse Large B-cell Lymphoma (DLBCL). She underwent chemotherapy with complete resolution of her mass and lymphadenopathy. Conclusion: We are presenting a rare case of Non - Hodgkin lymphoma in the colon. This disease can show up with unclear symptoms, so it's important to use different types of imaging and pathology tests to identify the specific type of lymphoma. The main treatment for this type of cancer involves using chemotherapy and radiation therapy.

Probiotics and Fecal Transplant: An Intervention in Delaying Chronic Kidney Disease Progression?

Chronic kidney disease (CKD) is a global health challenge affecting nearly 700 million people worldwide. In the United States alone, the Medicare costs for CKD management has reached nearly USD 80 billion per year. While reversing CKD may be possible in the future, current strategies aim to slow its progression. For the most part, current management strategies have focused on employing Renin Angiotensin Aldosterone (RAS) inhibitors and optimizing blood pressure and diabetes mellitus control. Emerging data are showing that a disruption of the gut-kidney axis has a significant impact on delaying CKD progression. Recent investigations have documented promising results in using microbiota-based interventions to better manage CKD. This review will summarize the current evidence and explore future possibilities on the use of probiotics, prebiotics, synbiotics, and fecal microbial transplant to reduce CKD progression.

Acute Pancreatitis as an Unusual Culprit of Diabetic Ketoacidosis in a Nondiabetic: A Case-Based Review.

Acute pancreatitis has been associated with a multitude of complications including pancreatic necrosis, pseudocysts, abscesses, acute respiratory distress syndrome, disseminated intravascular coagulation, and hyperglycemia. To date, only rare case reports have demonstrated diabetic ketoacidosis (DKA) as a rare sequela of acute pancreatitis. We report a case of a 34-year-old female with no prior history of diabetes who was subsequently diagnosed with DKA after presenting with severe acute pancreatitis. This case serves as a framework to not only highlight DKA as a rare complication of acute pancreatitis but also to explore the potential pathophysiology that underlies this phenomenon including stress hyperglycemia and post-pancreatitis diabetes mellitus.

Unique Variant of Zieve Syndrome With a Normal Reticulocyte Count.

Zieve syndrome is a rare diagnosis seen in patients with chronic alcohol use which consists of a distinct clinical triad of hyperlipidemia, hemolytic anemia, and jaundice. Patients typically have an elevated reticulocyte count due to the hemolytic nature of the anemia. We present the case of a 44-year-old female who was discovered to have an unusual variant of Zieve syndrome with a normal reticulocyte count, which was believed to be due to suppression of bone marrow from excessive alcohol consumption. She was treated with steroids and complete alcohol cessation, with remarkable improvement on subsequent follow-up. An exhaustive literature review of 31 documented cases of Zieve syndrome was conducted to better understand the clinical presentation and overall prognosis of these patients. This case report and literature review aimed to improve patient outcomes through increased recognition of this underrecognized syndrome.

Gastric Outlet Obstruction Caused by Acute Gastric Volvulus: A Rare Complication of Hiatal Hernia.

Hiatal hernias are commonly encountered in elderly patients, predisposing patients to the common condition of gastroesophageal reflux disease (GERD). Depending on the size of the hernia, different complications can arise. Large hernias can lead to development of gastric volvulus, obstruction, strangulation, and perforation. Therefore, management of large hiatal hernias is crucial to avoid such complications. In this paper, we describe a patient who presented with acute gastric volvulus secondary to a large hiatal hernia. She improved with conservative management and subsequently underwent successful repair of the hernia. We emphasized the importance of identifying gastric volvulus among its vague presentation for prompt management.

Ominous Sign of Pneumatosis Intestinalis With Portal Venous Gas.

The presence of gas and free air in the extraluminal space of the intestines is known as pneumatosis intestinalis (PI). There are many different causes of this finding, including gastrointestinal, pulmonary, autoimmune, and many more. It is often difficult to differentiate the etiology and clinical importance of the radiographic evidence on pneumatosis intestinalis due to the unclear pathophysiology causing the disease. To complicate things further, the ominous sign of portal venous gas poses the question of whether surgical intervention is needed. We report two cases both with clinical and radiographic evidence of secondary pneumatosis intestinalis with an associated sinister finding of portal venous gas. The cases differ by urgent surgical intervention versus observation before surgery. In this case series, we emphasize the importance of recognizing the radiographic finding and stress the need for further research to standardize a plan of care, including indications for surgery. We encourage more cases like this to be reported to aid in diagnosing and treating this condition early on with the aim of improving the mortality associated with it.

Fulminant Presentation of Budd-Chiari Syndrome Secondary to COVID-19 Infection.

Budd-Chiari syndrome (BCS) is a rare condition characterized by the obstruction of hepatic venous outflow. It is estimated to affect 1 in 100,000 people worldwide. In cases of new BCS, inherited and acquired hypercoagulability states must be evaluated. Coronavirus disease 2019 (COVID-19) can induce a hypercoagulable state because of its extensive inflammatory response, and while it has been reported to cause portal vein thrombosis, it rarely causes BCS. This article presents a case of a 22-year-old man who developed fulminant symptoms and was subsequently diagnosed with BCS and portal vein thrombosis secondary to COVID-19 infection, after ruling out other inherited and acquired causes of BCS. In addition, a literature review is provided to understand the presentation and management of such patients. Although most patients improve with medical management, this article emphasizes the consideration of liver transplant for patients who do not improve.

Metachronous Squamous Cell Carcinoma of the Esophagus After Resolution of Previous Adenocarcinoma.

Esophageal cancer is the sixth leading cause of cancer-related death worldwide. Metachronous malignancies refer to multiple independent primary cancers diagnosed at least 6 months apart. The incidence of metachronous esophageal cancers with different histologic subtypes is extremely rare. This case presents an unprecedented occurrence of esophageal adenocarcinoma, followed by metachronous squamous cell carcinoma.

Severe Gastrointestinal Hemorrhage due to Monkeypox Virus-Associated Proctocolitis.

Monkeypox is primarily a painful cutaneous disease with occasional systemic manifestations. Monkeypox is transmitted predominantly through close physical contact and occasionally sexual contact. The first case was reported in the United States on May 17, 2022, in a recent monkeypox worldwide outbreak. We present a case of severe gastrointestinal bleeding as an atypical manifestation of monkeypox infection in a 40-year-old male with HIV. In our case, monkeypox-induced proctocolitis progressed to severe rectal bleeding requiring one unit of packed red blood cells transfusion despite one week of tecovirimat (TPOXX) therapy. So, patients should be educated about the possibility of unusual complications of monkeypox infection, i.e., bleeding in immunocompromised hosts.

A Rare Case of COVID-19 Vaccination-Induced Cholangiopathic Liver Injury.

Drug-induced liver injury is a serious adverse drug reaction that can result in acute liver injury or cholestatic injury affecting the bile ducts, known as cholangiopathic liver injury (CLI). Although CLI is not as familiar as the hepatocellular pattern, emerging evidence suggests that it may occur after coronavirus disease 2019 (COVID-19) vaccination. This case report focuses on an 89-year-old woman who developed CLI after receiving the tozinameran COVID-19 vaccine. The main aim of this report was to raise awareness of the possibility of developing CLI after COVID-19 vaccination and to underscore the critical significance of promptly identifying and managing this infrequent but severe side effect.

Appendiceal Bulge on Routine Colonoscopy: Not All Disease Is Luminal.

Appendiceal mucocele is an extremely rare pathology accounting for 0.3-0.7% of all appendiceal pathology. It is characterized by appendiceal lumen dilatation by mucinous secretion collection. Though abdominal imaging and tissue Biopsy aids in diagnosis, suspicion should arise when a slight bulge or protrusion is seen on colonoscopy. We present a case of incidental appendiceal bulge found on a routine colonoscopy to evaluate abdominal pain that led to prompt diagnosis and management of appendiceal mucocele.

Rare Presentation of Stercoral Ulcer Spontaneous Perforation Without Preceding Radiographic Evidence of Colonic Inflammation and Fecal Impaction.

Stercoral ulcers are caused by persistent fecal impaction. A life-threatening consequence of stercoral ulcers is colonic perforation, which is rare. A high index of clinical suspicion should be held for patients with stercoral ulcer, as colonic perforation is a medical emergency, requiring immediate surgical intervention. Here, we report a case of a 45-year-old female admitted with sepsis of unknown picture and subsequently developed stercoral ulcer perforation (SUP), diagnosed intraoperatively, without prior radiographic evidence of colonic inflammation. She was successfully managed with emergency laparotomy and left colectomy with sigmoid colectomy.

Chronic Pancreatitis-Induced Thrombosis of Celiac and Superior Mesenteric Artery.

Every year, nearly 60,000 hospitalizations occur in the United States due to chronic pancreatitis (CP). CP can cause severe chronic abdominal pain, pancreatic insufficiency, and increased risk of pancreatic cancer. While venous thrombotic complications are common, arterial thrombotic events are rarely reported in CP. This report describes a case of a 43-year-old female who presented with severe worsening abdominal pain due to CP. Diagnostic imaging disclosed thrombosis of superior mesenteric artery (SMA) and celiac artery (CA) with acute bowel wall changes reflecting ischemic changes, resulting in acute-on-chronic mesenteric ischemia. Endovascular stent placement relieved the ischemia with the resolution of pain. Arterial thrombosis should be considered as a diagnostic possibility when patients with CP present with a significant change in symptoms. Importantly, the case demonstrates that endovascular treatment with stent placement can relieve ischemia and resolve symptoms in patients with CP.

Preventive Saline Irrigation of the Bile Duct to Reduce the Rate of Residual Common Bile Duct Stones Without Intraductal Ultrasonography: A Systematic Review and Meta-Analysis.

Endoscopic retrograde cholangiopancreatography (ERCP) with endoscopic sphincterotomy (EST) has been proven efficacious in the removal of CBD stones. Even after endoscopic stone removal, recurring cholangitis due to a residual common bile duct (CBD) stone is prevalent in clinical practice with a residual recurrence rate of 4-24% after successful stone retrieval. This comprehensive study and meta-analysis aimed to determine if preventive saline irrigation of the bile duct (PSIB) reduces the amount of residual CBD stones. Through a comprehensive search of PubMed, EMBASE, Cochrane Library, and Web of Science until November 20, 2022, we identified 164 articles comparing the efficacy of PSIB and non-PSIB post-endoscopic CBD stone removal. After stringent selection, three studies were included for meta-analysis using ReviewManager (ReVman version 5.4.1; Cochrane, London, UK). Using a random effect (RE) model, we derived a pooled odds ratio (OR) with confidence interval (CI) (95%CI). A total of three studies have been included in the analysis. Out of which, two are randomized controlled trials (RCTs) and one is a non-randomized study. Out of 323 patients, 157 underwent PSIB after an endoscopic stone removal of CBD stones to reduce the residual of CBD stones, whereas 166 did not undergo saline irrigation (non-PSIB). In our analysis, PSIB significantly reduced the risk of residual stones (OR: 0.22, 95%CI: 0.11-0.45). However, there was no notable link between PSIB and post-irrigation cholangitis (OR: 1.08, 95%CI: 0.21-2.21). Although not statistically significant, PSIB showed a trend toward lowered risks of post-procedural pancreatitis (OR: 0.65), bleeding (OR: 0.68), and other complications (OR: 0.64). PSIB effectively reduces residual CBD stones after endoscopy, offering a cost-effective alternative to invasive procedures such as intraductal ultrasound (IDUS). However, larger RCTs are needed to validate its definitive role.

Role of Plasmapheresis in Hemolysis, Elevated Liver Enzymes and Low Platelets (HELLP) Syndrome.

Hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome is a rare abnormality comprising a series of symptoms that make up a syndrome. It usually happens during pregnancy or right after delivery. We describe a case of a 31-year-old female G4P2A2 (Gravida 4 Para 2 Abortions 2) who presented to the hospital for normal vaginal delivery but immediately postpartum developed HELLP syndrome. Acute fatty liver of pregnancy was a differential that the patient also met the criteria for. Her condition improved after starting her on plasmapheresis without considering hepatic transplantation. We emphasize distinguishing the overlap of symptoms between HELLP syndrome vs. acute fatty liver of pregnancy and the outcomes of plasmapheresis in managing HELLP syndrome without needing hepatic transplantation.

Isolated Colonic Histoplasmosis in Patients Undergoing Immunomodulator Therapy: A Systematic Review.

Gastrointestinal histoplasmosis remains an inconspicuous clinicopathologic entity. It is predominantly considered a protean manifestation of disseminated disease. We hereby delineate a unique case of biopsy-proven isolated colonic histoplasmosis in a patient undergoing methotrexate therapy. Furthermore, we present the first systematic review of the MEDLINE, Google Scholar, Embase, and Scopus databases regarding isolated colonic histoplasmosis in adult patients receiving immunomodulator therapy (IMT). A total of 13 case reports (level of clinical evidence: IV) were identified. The mean age was 55.6 ± 11.1 years, with 9 (69.2%) cases reported in women. Patients with subclinical disease (5, 38.5%) were often incidentally diagnosed by screening colonoscopy. Symptomatic individuals predominantly presented with diarrhea (4, 30.8%), weight loss (3, 23.1%), and/or abdominal pain (3, 23.1%). IMT was mainly administered for liver transplant (4, 30.8%), renal transplant (4, 30.8%), and ulcerative colitis (2, 15.4%). Common colonoscopy features included colonic ulcerations (7, 53.8%), polyps or pseudopolyps (3, 23.1%), and/or mass-like lesions (3, 23.1%). Diagnosis was made by histology of colonic biopsy in 11 (84.6%) and resected specimens in 2 (15.4%) patients. Treatment consisted of a combination of amphotericin B with oral itraconazole in 6 (46.2%), oral itraconazole alone in 5 (38.5%), and amphotericin B alone in 2 (15.4%) patients. Complete clinical recovery was achieved in all patients. This article illustrates that isolated colonic involvement can be the only clinical presentation of histoplasmosis. It may masquerade as other bowel disorders, presenting diagnostic and therapeutic conundrums. Gastroenterologists should rule out colonic histoplasmosis in IMT recipients who develop unexplained colitis symptoms.

Operator-specific outcomes in endoscopic sleeve gastroplasty: a propensity-matched analysis of the US population using a multicenter database.

Background: Endoscopic sleeve gastroplasty (ESG) has emerged as an effective endoscopic bariatric procedure over the past decade. Data comparing short-term outcomes of ESG based on operator specialty is scarce. We aimed to assess the impact of operator specialization on patient outcomes using a large bariatric-specific database. Methods: We identified a retrospective cohort of patients who underwent ESG by gastroenterologists using the Metabolic and Bariatric Surgery Accreditation Quality Improvement Program database (2020-2021). A matched comparison cohort of patients who underwent ESG by surgeons was identified and underwent 1:1 propensity score matching based on age, race, gender, American Society of Anesthesiologists physical status classification, and preoperative body mass index. Results: After matching, 154 patients were included in the final analysis. Of these, 77 patients underwent ESG by surgeons and 77 by gastroenterologists. In the matched cohort, the median operation time was lower in ESG by surgeons compared to gastroenterologists (P < 0.001). The median percent body mass index decrease was higher in the gastroenterologist cohort compared to the surgeon cohort (4.9% vs 3.8%, P = 0.04). The median percent weight loss after ESG was 4.8% in the surgeon cohort and 5.9% in the gastroenterologist cohort (P = 0.09). There was no statistically significant difference in postoperative emergency department visits (P = 0.65), reoperations (P = 0.15), or reinterventions within 30 days (P = 0.87) between the cohorts. There was no difference in major adverse effects between the groups (0% each). Conclusions: Operator choice does not affect ESG-related adverse events or 30-day outcomes in patients undergoing ESG.

Association of nonalcoholic fatty liver disease with acute cholangitis: a nationwide propensity-matched analysis from the United States.

Background: Nonalcoholic fatty liver disease (NAFLD) has previously been linked to several disease states with an impact on patient outcomes. However, clinical evidence on the association between NAFLD and acute cholangitis (AC) remains scarce. We aimed to evaluate the potential association between NAFLD and AC. Methods: We conducted a retrospective cohort study using the US National Inpatient Sample database from 2016 to 2019 to analyze primary AC hospitalizations with NAFLD compared to non-NAFLD in a 1:1 propensity-matched population. Results: A total of 1550 AC patients with NAFLD were matched to 1550 AC patients without NAFLD. NAFLD had a higher association with AC when compared to patients without NAFLD, with an odds ratio of 2.33 (95% CI [1.81-3.0], P < 0.001). The length of stay was higher in NAFLD than in non-NAFLD (4 vs 3 days, P < 0.001). The median inpatient charges in NAFLD were also higher than in the non-NAFLD cohort ($36,182 vs $35,244, P < 0.001). Inpatient mortality was higher in NAFLD compared to non-NAFLD (1.6% vs 0%, P < 0.001). There was an increased prevalence of portal vein thrombosis (3.2% vs 0%), acute kidney injury (24.2% vs 17.7%), sepsis (3.2% vs 1.6%), mechanical ventilation (3.2% vs 0%), and percutaneous cholecystostomy tube insertion (3.2% vs 1.6%) in NAFLD compared to non-NAFLD (P < 0.05). NAFLD also had a higher association with acute cholecystitis, with an odds ratio of 3.70 (95% CI [3.19-4.29], P < 0.001). Conclusions: This study showed an association between NALFD and AC, resulting in increased length of stay, hospital charges, and inpatient mortality. Underlying NAFLD also increases acute complications of AC.
