Intermittent Hiatus Hernia on High-Resolution Manometry Associates With Abnormal Reflux Burden Similar to Persistent Hiatus Hernia.

INTRODUCTION: Hiatus hernia is characterized by axial separation between the lower esophageal sphincter and the crural diaphragm, and higher reflux burden. Impact on reflux is unclear if such separation is intermittent rather than persistent. METHODS: Reflux burden off antisecretory therapy was compared between no hernia (n = 357), intermittent hernia (n = 42), and persistent hernia (n = 155) after review of consecutive high-resolution manometry and reflux monitoring studies. RESULTS: Proportions with pathologic acid exposure was similar between intermittent and persistent hernia (45.2% vs 46.5%, respectively), and both were significantly different from no hernia (28.7%, P ≤ 0.002). DISCUSSION: Intermittent hiatus hernias are clinically relevant in gastroesophageal reflux pathophysiology.

Pulmonary Hypertension as a Rare Complication After Orthotopic Liver Transplant in a Patient With Non-alcoholic Steatohepatitis (NASH) Cirrhosis Complicated by Hepatopulmonary Syndrome.

Hepatopulmonary syndrome is a phenomenon that results in an intrapulmonary shunt leading to dyspnea and hypoxemia with poor response to oxygen supplementation. It is now an indication for liver transplantation; however, some transplants result in subsequent pulmonary hypertension. Postulated mechanisms include unmasking of underlying pulmonary hypertension with liver transplant and increased pulmonary vascular resistance due to increased blood flow in hepatopulmonary syndrome. In this case, we describe pulmonary hypertension developing after orthotopic liver transplant in a cirrhotic patient with hepatopulmonary syndrome.

Infliximab-Induced Vanishing Bile Duct Syndrome.

Drug-induced liver injury (DILI) is a spectrum of pathology that can be classified by mechanism of injury or by type of observed hepatotoxicity. Vanishing bile duct syndrome (VBDS) is a group of acquired and genetic disorders that cause the destruction and disappearance of intrahepatic bile ducts, and cholestasis. VBDS typically presents with severe cholestatic hepatitis and can have immunoallergic features. Infliximab has been reported to rarely cause a cholestatic pattern of liver injury due to ductopenia characteristic of VBDS. Herein we present a clinical case of infliximab-induced DILI resulting in VBDS.

Serrated polyp detection rate in colonoscopies performed by gastrointestinal fellows.

Background: Clinically significant serrated polyp detection rate (CSSDR) and proximal serrated polyp detection rate (PSDR) have been suggested as the potential quality benchmarks for colonoscopy (CSSDR = 7% and PSDR = 11%) in comparison to the established benchmark adenoma detection rate (ADR). Another emerging milestone is the detection rate of lateral spreading lesions (LSLs). Objectives: This study aimed to evaluate CSSDR, PSDR, ADR, and LSL detection rates among gastrointestinal (GI) fellows performing a colonoscopy. A secondary aim was to evaluate patient factors associated with the detection rates of these lesions. Design and Methods: A retrospective review of 799 colonoscopy reports was performed. GI fellow details, demographic data, and pathology found on colonoscopy were collected. Multiple logistic regression analysis was performed to identify the factors associated with CSSDR, PSDR, ADR, and LSL detection rates. A p value < 0.05 was considered statistically significant. Results: For our patient population, the median age was 58 years; 396 (49.8%) were male and 386 (48.6%) were African American. The 15 GI fellows ranged from first (F1), second (F2), or third (F3) year of training. We found an overall CSSDR of 4.4%, PSDR of 10.5%, ADR of 42.1%, and LSL detection rate of 3.2%. Female gender was associated with CSSDR, while only age was associated with PSDR. GI fellow level of training was associated with LSL detection rate, with the odds of detecting them expected to be four times higher in F2/F3s than F1s. Conclusion: Although GI fellows demonstrated an above-recommended ADR and nearly reached target PSDR, they failed to achieve target CSSDR. Future studies investigating a benchmark for LSL detection rate are needed to quantify if GI fellows are detecting these lesions at adequate rates.

Primary lung sarcoma with gastric metastasis and morphological divergence presenting as melena.

A 61-year-old man was admitted to the medical intensive care unit following a 2-week history of weakness, lightheadedness and melena resulting in an acute anaemia. Upper endoscopy revealed multiple large gastric masses without evidence of active bleeding. CT of the chest revealed a large right upper lobe mass with bony destruction of the third rib and invasion into the anterior chest wall and mediastinum, as well as a soft-tissue density in the left kidney. Biopsy and histopathological review of both pulmonary and gastric masses revealed two distinct sarcomatous malignancies that, while both from a primary lung source, differed in their morphology. Natural history and behaviour are not well understood in sarcomas due to their rarity, but abdominal metastasis is considered an uncommon event in the progression of the disease. Gastrointestinal bleeding as the presenting symptom of a primary lung sarcoma is an atypical finding with no previously reported cases.

Case Report: Syphilitic Hepatitis-A Rare and Underrecognized Etiology of Liver Disease With Potential for Misdiagnosis.

Syphilitic hepatitis (SH) in adults is a rare condition that can be easily misdiagnosed. Clinical and histopathologic manifestations of SH can mimic other infectious and non-infectious conditions, and the diagnosis should be considered in all at-risk patients with abnormal liver function tests. We present an unusual case of SH presenting with seizures and multiple liver lesions. This case report, in line with other newly published reports, promotes awareness of SH as a rare manifestation of treponemal infection and highlights the importance of including SH in the differential diagnosis for patients at risk for sexually transmitted infections and presenting with liver enzyme abnormalities. From a hospital quality control and socioeconomic perspective, our case adds to the growing body of evidence that demonstrates an increasing incidence of patients suffering from venereal diseases and injection drug use disorders, and the burden these conditions place on the healthcare system. Recognition of the clinicopathologic features of SH is required to prevent missed diagnosis and to foster systematic crosstalk between healthcare staff and public health personnel managing this problem.
