Adenocarcinoma of the duodenojejunal angle (The Angle of Treitz): Diagnostic and therapeutic difficulties: About 02 cases

“…Adenocarcinomas usually present in the 6th and 7th decades [5,7], The mean age at presentation of these tumors is 67 years with higher prevalence in blacks than whites and men than women. 3 The epidemiology of these tumors favors men to women at a rate ratio of 1.5:1.3 [6]. Our two patients are male, the adenocarcinoma was discovered in the 5 th decade, respectively at 51 and 58 years old.…”

“…Most tumors of the angle of Treitz are gastrointestinal stromal tumors (GISTs), adenocarcinomas are rare [4]. The extreme rarity and vagueness of presenting symptoms (Symptoms are often nonspecific (anemia, vague abdominal pain, dyspepsia) makes it hard to diagnose these tumors [3,5,6].…”

“…This non-specific nature of the symptoms makes that the diagnosis is often late, moreover, in our second patient the tumor was palpable at the time of diagnosis. The localization at the angle of Treitz presents another diagnosis problem, which is the inaccessibility of the area by methods conventional endoscopy makes the diagnosis difficult [3,8,9]. barium meal radiography of the digestive tract is useful for detecting endoluminal diseases.…”

“…Adenocarcinomas of the small intestine represent less than 2% of digestive tumors [2]. Among these tumors, the duodenojejunal angle location (The angle of Treitz) is exceptional [3]. The most tumors of the angle of Treitz are gastrointestinal stromal tumors (GISTs), and only a few are adenocarcinomas [4].…”
