*- Chronic peptic ulcer Etiology: Increased gastric acidity is the main association, multifactorial by * Genetic predisposition (large mass) * Increased vagal tone mainly by night may be by worry or stress * Abnormality in gastrin release and inhibition * Helicobacter pylori causing gastritis, duodenal ulcer and sometimes MALT lymphoma. * Hypergastrinaemia by pancreatic (Zollinger Ellison syndrome) * Spicy meals, drinks, smoking, alcohol , drugs,

Clinical presentation: Incidence: *- Pain (post prandial , localized , deep, severe, Decreasing incidence of ulcer disease with 50-60% increased by codiments, wores by night) increased GE reflux and gastritis More common in males (5:1), age is around middle *- and vomiting age (??) *- Periodicity (periods of activity followed by DU : GU = 25 : 1 period of quiescence),loss of periodicity signats

15-20% 15-20% complications , penetration, or spastic pyloric Pathology: stenosis Site gastric , duodenal (Kissing ulcers) Size Single or multiple *- Complications as bleeding (, or Shape Edge Floor Base , hematochasia?? ), penetration (), perforation (), or ?10% pyloric obstruction.

Investigations *- (diagnosis, Biopsy)

*- Barium meal

Treatment: (Peptic ulcer treatment is mainly medical, *- Mucosal protective drugs: surgery has selective indications only) ( Sucralfait, or prostaglandin analogue,) I- Medical treatment *- : *- Complete physical and mental rest. (Aluminum hydroxide, …..) *- Dietary regimens. *- Anti HP drugs, and their regimens. *- H2 receptor antagonists: (Dual therapy, Triple therapy, or Quadruple (Cimetidine 800 mg, Ranitidine 300 mg, Famotidine therapy). 40 mg, Nizatidine 300 mg, or Ruxatidine ??) *- Other drugs *- Proton pump inhibitors (No acid-No ulcer): Sedative tranquilizers, prokinetics, digestants,.. (Omeprazole 20 mg, Lanzoprazole, Pantoprazole, Rapeprazole, or Esomprazole)

II- Surgical treatment Initial treatment Recurrent ← (4-6 or 8 weeks) ulcer Gastric ulcer: Mainly caused by local defect in mucosal ↘ ↓ Once ulcer Intractable ulcer barrier, or local insult, so the treatment is by Re-endoscopy → Non healed ulcer gastrectomy (remove the ulcer or the bearing area, and ensure gastric emptying). ↓ ↘ ↘ Surgical ↓ Duodenal ulcer: Bad patient treatment Healed ulcer → Mainly caused by hypersecretion either due to compliance ↑ increased vagal tone (treated by vagotomy ± ↓ Always ulcer drainage procedure), increased gastrin level Maintenance therapy Complicated → Follow up (treated by anterectomy), or large parietal cell Interval therapy ulcer mass (treated by gastrectomy).

Vagotomy: abolishing entirely the pathway of gastric secretion with immediate reduction of HCL secretion in 80 %, with time it decreased to 50 %. *- Truncal vagotomy + drainage procedure *- Selective vagotomy + drainage procedure *- Highly selective vagotomy (parietal cell vagotomy) (proximal gastric vagotomy) *- lesser curve seromyotomy (+posterior truncal vagotomy) (Taylor operation)

6 Prof. Alaa Ahmad Redwan, 2017 19 September 2018

Drainage procedures: *- Pyloomyotomy (Rammstedt) *- Heineke-Mikulicz pyloroplasty *- Finney pyloroplasty *- Jaboulay pyloroplasty *- Antrectomy + reconstruction ( Billroth I, Billroth II, Polya , or others) *- Gastrojejunostomy ( loop with or without enteroenterostomy, antecolic or retrocolic, isoprestaltic or antiprestaltic, short afferent or ultrashort afferent limb, Roux-en-Y loop.
