Wilkie’s Syndrome (WS) was described in 1927 and its physiopathology is related to the formation of an abnormal acute aortomesenteric angle measuring between 7o and 22o. It leads to digestive symptoms due to external compression of mesentery artery against the third portion of duodenum. This is a case of WS in a young, tall and slim male patient. Three months before, he began postprandial vomiting, abdominal pain, hyporexia and weight loss. The diagnostis was made by an upper gastrointestinal series with barium contrast and confirmed by Laparotomy. Duodenojejunostomy is a well-known technique and it was successfully performed in this case.
Helicobacter pylori (HP) infection is present in more than the half of the world population. Most individuals are infected during early childhood; in developing countries, 50% of children are infected by the age of 5 years [1,2]. Studies suggest the main etiological role of HP infection in development of chronic gastroduodenal pathology and the formation of its most severe forms in patients of different age groups. However, not all infected people exhibit diseases associated with this bacterium. In addition, pathogenic mechanisms of duodenal ulcer disease (DUD) in childhood remain not fully understood.
Sphincter of Oddi dysfunction (SOD) is a known gastrointestinal disorder that has been well documented but is difficult to diagnose noninvasively.
Esophageal carcinoma is the eighth most common cancer, and the sixth most common cause of cancer-related deaths worldwide. Esophageal carcinomas in developing nations account for more than 80% of the total cases and deaths. Esophageal cancer can arise as esophageal squamous cell carcinoma (ESCC) or esophageal adenocarcinoma (EAC), which have distinct etiological and pathological characteristics. ESCC is the most common histological type of esophageal cancer in the Eastern world, and its incidence remains stable. In contrast, the epidemiology of esophageal cancer in developed nations has dramatically changed over the past 40 years. Forty years ago, ESCC accounted for more than 90% of esophageal cancer cases in the United States. However, adenocarcinoma has now become the leading type of esophageal cancer in the United States, representing 80% of cases.
Gastric Type Adenocarcinoma with Fundic Gland Differentiation in the Duodenum Resected by ESD (Endoscopic Submucosal Dissection)
Gastric type adenocarcinoma with fundic gland differentiation (GA-FG) has been reported as a new, rare, chief cell differentiation composed carcinoma. Clinicopathologically, it exists on the gastric cardia/fundus, with low proliferative activity and low-grade malignancy. Until now, there has been no report of this GA-FG type cancer in the duodenum.
