Management Of Refractory Ulcers

Diagnostic Approach-Exclude H.pylori (use more than 1 test) and biopsy everything.-Fasting serum gastrin should be measured to exclude gastrinoma and antral G cell hyperfunction but caution is necessary because both PPI and H. pylori can raise gastrin levels.-Plasma salicylate levels. Refractory or recurrent peptic ulcer disease Refractory Ulcers — (= No healing after >8weeks treatment)25 % of refractory ulcers are asymptomatic. TreatmentPPIs heal ulcers > H2-receptor antagonists. (85% vs 75% at 4 weeks).Healing of the DU is likely to occur if the gastric pH > 4 for 90 % of the day (stops pepsin from working and being generated).If cause has been removed, but refractory ulcer, continue PPI.No evidence for PPI + H2 antags.Surgery may be necessary. Conditions underlying refractory and recurrent ulcers.Persistent H. pylori infection can contributeNSAIDs account for 40% — 44% discovered by measuring platelet cyclooxygenase activity; salicylate levels should be measured.Large ulcers — Large and small PUD heal at the same rate on antacids, approximately 3 mm per week.Ulcer healing was less likely in ulcers ≥10 mm in diameter.Big ulcers also are often densely scarred.Smoking contributes to impaired healing but may not be a risk factor once H. pylori is eradicated.Acid hypersecretory states can occasionally due to gastrinoma.In nongastrinoma refractory DU, increased basal, nocturnal, and maximal acid secretion may be a contributing factor in a subset of patients.Atrophic gastric predicts enhanced healing, an effect presumably due to lower levels of acid secretion.Impaired response to antisecretory agents can occur.H2 receptor antagonists tolerance can develop.Poor response to PPI is probably P450 mediated rapid metabolism.Comorbid diseases may promote ulcer formation and complications and impair healing. Factors influencing recurrence:The quality of duodenal ulcer healing- this reflects the degree of restoration of normal epithelial architecture.Marked inflammation.An absence of glandular structure.Blunt or absent villi- markers of poor histologic restoration.Duodenal bulb deformity-presumably due to dense scarring, and gastric metaplasia in the duodenum have also predicted DU recurrence.A prior history of ulcer complications-predicts complicated recurrence.A history of prior frequent recurrences or ulcers refractory to initial therapy. Prevention and treatment — Maintenance therapy is indicated to prevent recurrence in high-risk subgroups, defined by a history of complications, frequent recurrences, or refractory, giant, or severely fibrosed ulcers.Recurrences on maintenance therapyAsymptomatic recurrences account for 25 to 40 % of recurrences on therapy for both DU and GU.Ulcers that occur on maintenance therapy are more likely to be asympto-matic.
