Clinical Picture.

Management.

DEFINITIONBreak in the gastrointestinal mucosa exposed to the aggressive action of acid-peptic juices.

Common sites are the first part of the

duodenum and the lesser curve of the

stomach.

The gastroduodenal mucosal integrity is determined by protective (defensive) & damaging (aggressive) factors.

PATHOPHYSIOLOGY

Pathophysiology• Bicarbonate• Mucus layer• Prostaglandins• Mucosal blood flow• Epithelial renewal

Defensive

• Helicobacter pylori• NSAIDs• Pepsins• Bile acids• Smoking and alcohol

Aggressive

Mucosal damage erosions & ulcerations

ETIOLOGY H. Pylori Infection

NSAIDs

Smoking & Alcohol

Acid Hypersecretion

Stress

Family History of PUD.

Management

Medical.

Surgical.

LIFE STYLE MODIFICATION

Discontinue NSAIDs

Smoking cessation.

Alcohol cessation.

Stress reduction.

AntacidsH2-receptor blocking

agents. Proton pump inhibitors.Cytoprotective and

antisecretory drugs.Antibiotics.

MEDICATIONS

MEDICATIONSH. pylori Eradication Therapy:• Triple therapy:

Proton pump inhibitor . 2 Antibiotics:

• Metronidazole + Clarithromycin.• Clarithromycin + Amoxicillin.

» In some regimens, H2-receptor blockers, e.g. ranitidine, are used instead of PPI.

Indications:

Failure of medical treatment.

Development of complications

High level of gastric secretion and

combined duednal and gastric ulcer.

SURGICAL

Principle:

Reduce acid and pepsin

secretion.

Vagotomy:

Truncal Vagotomy with drainage.

Highly selective Vagotomy.

Combination of vagal

denervation (vagotomy) +

anterctomy.

SURGICAL

VagotomyTruncal vagotomy with drainage:

Resect the major trunk of the vagus to

the stomach this will lead to:Decrease acid and pepsin secretion.

Impair antral motility and drainage.

–Two types of drainage:Pyloroplasty.Gastrojejnostomy.

Pyloroplasty Drainage

Gastrojejunostomy Drainage

Highly selective vagotomy:

• It is a parietal cells vagotomy.• It can be done with or without

drainage.• It is done by cut a branch

of vagus of the body and the fundus this will lead to decrease HCl production.

Vagotomy

Combination of vagotomy+

anterctomy:Combination of vagal denervation & removal of the major area of gastric production.

Vagotomy

Gastrointestinal continuity is restored by gastroduodenal (Billroth 1) anastomosis OR gastrojejunal (Billroth 2) anastomosis.

Dehiscence.Stenosis of

anastomosis.Bleeding.Injury to neighbour

tissues.Dumping

syndrome

Vagotomy

Hemorrhage

Perforation peptic ulcer

Gastric outlet obstruction
