Evaluation & Management of Peptic Ulcer Disease | Surgery | Bailey learned with Dr. Sandeep
PW MedEd
Overview
This video focuses on the evaluation and management of peptic ulcer disease (PUD), primarily from a surgical perspective. It details how patients present, the diagnostic tools used like upper GI endoscopy and biopsy, and the classification of gastric ulcers using the modified Johnson's classification. The video also covers the crucial evaluation for Helicobacter pylori (H. pylori) infection, explaining various diagnostic tests and the importance of stopping certain medications before testing. Finally, it delves into the management strategies, starting with medical treatment (triple and quadruple therapy) and progressing to surgical interventions like Billroth I and Billroth II surgeries when medical management fails.

Chapters
- The primary complaints in peptic ulcer disease are epigastric pain and upper gastrointestinal (GI) bleeding.
- Upper GI bleeding can manifest as hematemesis (vomiting blood) and melena (black, tarry stools), requiring at least 60 ml of blood to produce melena.
- Upper GI endoscopy is the initial diagnostic tool to visualize ulcers in the stomach or duodenum.
Understanding the typical presentation and initial diagnostic steps is crucial for quickly identifying and assessing patients with potential peptic ulcer disease.
A patient presenting with vomiting blood (hematemesis) and black, tarry stools (melena) is a classic sign of upper GI bleeding, prompting an urgent upper GI endoscopy.
- Gastric ulcers are considered potentially malignant until proven otherwise, necessitating biopsies.
- Duodenal ulcers are almost never malignant.
- The 'U maneuver' during upper endoscopy allows visualization of ulcers in the fundus of the stomach.
- Gastric ulcers are classified using the modified Johnson's classification (Types 1-5) based on their location and cause, guiding surgical planning.
Accurate classification of gastric ulcers is vital for determining the risk of malignancy and planning appropriate treatment, including the extent of surgical resection.
The modified Johnson's classification categorizes gastric ulcers: Type 1 on the lesser curvature (most common), Type 2 with ulcers in the stomach body and duodenum, Type 3 prepyloric, Type 4 high on the lesser curvature, and Type 5 NSAID-induced.
- H. pylori is a major cause of peptic ulcer disease, and its eradication is a key treatment goal.
- The CLO (Campylobacter-like organism) test, a rapid urease assay performed during endoscopy, is the preferred method for detecting H. pylori.
- Other H. pylori tests include histology, culture, urea breath test, antibody tests, and stool antigen tests, each with pros and cons.
- To avoid false negatives, antibiotics must be stopped 4 weeks and proton pump inhibitors (PPIs) 2 weeks prior to H. pylori testing.
Identifying and eradicating H. pylori is fundamental to treating PUD and preventing recurrence, as it directly contributes to ulcer formation and persistence.
During an upper endoscopy, a tissue sample from an ulcer is placed on a yellow strip in a CLO kit; if the strip turns purple, it indicates the presence of H. pylori due to its urease enzyme activity.
- The goals of medical management are H. pylori eradication and reduction of acid secretion.
- Triple therapy typically involves two antibiotics (e.g., clarithromycin with amoxicillin or metronidazole) and a PPI.
- Quadruple therapy adds an ulcer-protective agent like bismuth or sucralfate to the triple therapy regimen.
- Both triple and quadruple therapies are usually administered for 14 days, with quadruple therapy often preferred for better outcomes.
Medical management is the first line of treatment for PUD, aiming to heal ulcers and eliminate the underlying cause, thereby avoiding the need for surgery.
A common quadruple therapy regimen includes a PPI, bismuth, and two antibiotics (like tetracycline and metronidazole) taken together for two weeks to eradicate H. pylori and protect the ulcer.
- Surgery is considered when medical management fails or in cases of complications.
- Surgical goals include removing the diseased part, diverting acid, or reducing acid secretion.
- Billroth I surgery (gastroduodenostomy) involves resecting the distal stomach and anastomosing the remaining stomach directly to the duodenum.
- Billroth II surgery (or Polya surgery) involves resecting the distal two-thirds of the stomach and anastomosing the remaining stomach to the jejunum, bypassing the duodenum.
Surgical interventions offer definitive solutions for refractory PUD or its complications, aiming to control acid production and remove ulcerated tissue.
In Billroth I surgery, if an ulcer is in the antrum, that part of the stomach is removed, and the remaining stomach is sewn directly to the duodenum to restore continuity.
Key takeaways
- Peptic ulcer disease primarily presents with epigastric pain and upper GI bleeding, requiring prompt endoscopic evaluation.
- Gastric ulcers carry a risk of malignancy and require biopsies, while duodenal ulcers are rarely malignant.
- H. pylori is a critical factor in PUD, and accurate testing (like the CLO test) is essential for guiding treatment.
- Medical management focuses on H. pylori eradication and acid suppression using triple or quadruple therapy.
- Surgical options like Billroth I and II are reserved for cases where medical treatment is unsuccessful or complications arise.
- The choice between Billroth I and II depends on the ulcer location and the need to manage potential complications like bile reflux.
