Lymphocytic Esophagitis

Lymphocytic esophagitis is a new and rare entity, first described in 2006. Histologically, the esophageal mucosa is characterized by a dense peripapillary lymphocytic infiltrate and an intercellular edema without granulocytosis. To this day, it is not yet considered as a disease. Its etiology and clinical significance are still unclear. The predominant symptom is dysphagia and the main endoscopic feature is a normal esophagus. The absence of relationship between lymphocytic esophagitis and specific clinical conditions justifies further studies. Currently, it remains a histologic entity

Unusual Presentation of a Metastatic Esophageal Carcinoma

Esophageal cancer most commonly presents with upper digestive symptoms such as dysphagia. Lymph nodes are among the most common metastatic sites of this type of cancer. We report the case of a 53-year-old man presenting with unusual sole presenting features of esophageal cancer. The patient sought medical attention for abdominal pain without dysphagia, which was first investigated with an abdominal computed tomography scan. A large abdominal mass was discovered on imaging. Biopsies of this mass were in keeping with esophageal squamous cell cancer. With this finding, gastroscopy was performed, confirming the presence of primary esophageal cancer. This is a rare presentation of esophageal cancer without upper gastrointestinal symptoms. This case reinforces the value of biopsy for any neoplastic mass, especially in a context of unusual symptoms

Prevalence of Small Intestinal Bacterial Overgrowth among Chronic Pancreatitis Patients: A Case-Control Study

Background. Patients with chronic pancreatitis (CP) exhibit numerous risk factors for the development of small intestinal bacterial overgrowth (SIBO). Objective. To determine the prevalence of SIBO in patients with CP. Methods. Prospective, single-centre case-control study conducted between January and September 2013. Inclusion criteria were age 18 to 75 years and clinical and radiological diagnosis of CP. Exclusion criteria included history of gastric, pancreatic, or intestinal surgery or significant clinical gastroparesis. SIBO was detected using a standard lactulose breath test (LBT). A healthy control group also underwent LBT. Results. Thirty-one patients and 40 controls were included. The patient group was significantly older (53.8 versus 38.7 years; P < 0.01). The proportion of positive LBTs was significantly higher in CP patients (38.7 versus 2.5%: P < 0.01). A trend toward a higher proportion of positive LBTs in women compared with men was observed (66.6 versus 27.3%; P = 0.056). The subgroups with positive and negative LBTs were comparable in demographic and clinical characteristics, use of opiates, pancreatic enzymes replacement therapy (PERT), and severity of symptoms. Conclusion. The prevalence of SIBO detected using LBT was high among patients with CP. There was no association between clinical features and the risk for SIBO

High Prevalence of Esophageal Dysmotility in Asymptomatic Obese Patients

BACKGROUND: Obesity is an important health problem affecting >500 million people worldwide. Esophageal dysmotility is a gastrointestinal pathology associated with obesity; however, its prevalence and characteristics remain unclear. Esophageal dysmotilities have a high prevalence among obese patients regardless of gastrointestinal symptoms

Plasma Leptin Concentrations and Esophageal Hypomotility in Obese Patients

BACKGROUND: Although esophageal hypomotility is prevalent in obese patients, its cause remains unknown. Leptin, a hormone derived from adipose tissue, may be involved in this phenomenon because it has been shown to decrease gastric and intestinal motility in animals. It has been hypothesized that elevated plasma leptin concentration is a risk factor for esophageal dysmotility in obese patients
