Study Notes
Peptic Ulcer Disease (PUD)
- Peptic ulcer is a mucosal defect extending through the muscularis mucosa into deeper stomach or duodenal layers.
- Management is tailored to etiology, specific ulcer characteristics, and the expected natural history of the ulcer.
- PUD is primarily caused by an imbalance in mucosal defenses and acid peptic injury.
- Major risks include Helicobacter pylori infection and non-steroidal anti-inflammatory drugs (NSAIDs), both of which act independently and together to exacerbate PUD.
- Symptoms develop gradually and include early satiety, bloating, nausea, vomiting, epigastric pain post-meal, and weight loss.
- Complications from PUD can include significant bleeding, perforation, and gastric outlet obstruction.
Complications of PUD
- Bleeding Peptic Ulcer: Often arises from the posterior wall of the duodenum where the gastroduodenal artery is located. Can lead to acute, insidious abdominal pain.
- Perforation: Characterized by sudden, intense pain; managed using Graham's Patch, which involves omentum mobilization to occlude the affected area and promote healing.
- Gastric Outlet Obstruction: Resulting from scarring and narrowing of the pylorus or duodenum; may require endoscopic dilatation or surgical bypass if conservative management fails.
Surgical Interventions in PUD
- Elective surgery for PUD has declined due to the use of proton pump inhibitors and better management of H. pylori infections.
- Emergency surgery is vital for life-threatening complications unresponsive to medical therapies or endoscopic techniques.
Surgical Options
-
Ulcer Bed Management: Techniques range from localized treatments to comprehensive procedures.
-
Bleeding Management: Involves securing and ligating the bleeding vessel directly. Can apply modified Graham’s patch for closure and stability.
-
Gastric Outlet Obstruction Surgery:
- Gastrojejunostomy is performed by creating a bypass from the jejunum to the stomach, avoiding the narrowed pyloric channel.
- Vagotomy involves severing branches of the vagus nerve, decreasing gastric secretions but necessitating a drainage procedure to prevent obstruction of gastric contents.
Additional Notes
- Endoscopic balloon dilatation can be attempted for strictures but it is generally a temporary solution.
- Surgical options vary in complexity, with simple interventions directed at the ulcer bed being less invasive compared to more definitive surgeries like vagotomy.
