IntroductionMen are affected three times as often as
women Duodenal ulcers are ten times more
common than gastric ulcers in young patients
In the older age groups the frequency is about equal

DUODENAL ULCEREpigastric area, mid-day, noon,nightRelieved by foodNormal or increased acid secrtionCommon in young – middle age male95% in duodenal bulb (2cm)90% principle cause is H pylori (GNCB

DiagnosisEpigastric area pain and tendernessEGDGastric analysis ( basal vs maximal)Gastrin serum level (severe or refractory )Contrast meal (show complication)

TREATMENTMedical Treatment (80% in 6 weeks) -H2 antagonsis (zantac……) - Proton pump inhibetors (omperazol…..) - H.pylori eradication (amoxicillin ,
clarithro..) Surgical Treatment I. VagotomyII.Antrectomy and vagotomyIII.Subtotal gastrectomy

Complications of surgery for peptic ulcer Early Complications (leakage, bleeding,
retension)Late Complications1.Recurrent ulcer (marginal ulcer, stomal
ulcer ,anastomotic ulcer)2.Gastrojejunocolic and gastrocolic fistula3.Dumping syndrome4.Alkaline gastritis5.Anemia (Iron defi and vitB12 …) 6.Postvagotomy diarrhea7.Chronic gastroparesis

Brochardt’s triad1. Vomiting followed by retching and then
inability to vomit 2. Epigastric distention 3. Inability to pass a nasogastric tube
