Abstract

Aim of study


1. Classification of duodenal maglignant lesions


2. Evaluate the clinical and paraclinical characteristics of duodenal maglignant lesions.


Results: There were 34 patients, Male 20 patients, female 14 patients, mean age 64±8,48 year; Medical history:  Abdominal surgery in 26,5%. Clinical features:  Abdominal pain in 91,2%, Vomiting 58,8%, Hematemese in 5,9%, melena in 8,8%, intestinal obstruction in 5,9%; Gastric outlet obstruction in 44,1%. Gastroscopy revealed submucosa tumor (GIST) in 50%; For gastric tumor invaded duodenum: Gastroscopy showed 100% stricture of pylorus, of them  in 2 patients gastric tumor invading beyons pylorus into lumen of duodenum. CTScan finding: 100% duodenal GIST; 14,3% gastric tumor invading duodenum; 14,3% colonic cancer invading duodenum.


Conclusion: There were 6 group of o duodenal maglignant lesions: Duodenal GIST (1); Gastric cancer invading duodenum (2); Right colon cancer invaded or perfogated into duodenum (3); AC of duodenum (4); Lymphoma of duodenum (5); Leiomyoma of duodenum (6).


Clinical and paraclinical features:


- 100% tumor located at distal to the ampoule of Vater; abdominal pain in 100%; Hematemese in 5,9%, melena in 8,8%. CTscan revealed tumor in 100%, Gastroscopy showed submucosa tumor in 50%.


- Abdominal pain in 85,7%, vomiting in 64,3%, gastric outlet obstruction in 78,6%. Gastroscopy revealed gastric tumor invading pylorus in 100%, gastric tumor invading beyons pylorus in  2 patients.


- Intestinal obstruction or subobstruction in 100%, Gastroscopy revealed an  openning hole connecting lumen of duodenum D2 to right colonic lumen in 10%. CTScan showed  the right colonic tumor diameter > 5 cm in 50%, Irregular boder of colonic tumor in 40% (< 5 cm).


- Gastroscopy revealed tumor invading pylorus .


- Abdominal pain and subobstruction in 100%; CT Scan showed tumor in 100% (located at DIV)


- Hematemese and Melena. Gastrscopy: Bleeding in D2 Duodenum. Ctscan: active bleeding  from 0,6 cm actery of pancreatic head in to D2 below the ampoule of Vater.
