title: Giant gastric ulcer: its natural history and outcome in the H2RA era.
abstract: OBJECTIVE
  The aim of this paper is to study the natural history and outcome of medical treatment of giant gastric ulcer in the histamine H2-receptor antagonist era.
  
  
  METHODS
  All patients with gastric ulcer were prospectively followed. We assessed the special features (in particular, demography and treatment outcome) in patients with giant gastric ulcer, defined as ulcers large enough to occupy at least one wall.
  
  
  RESULTS
  Between 1976 and 1991, 537 patients with gastric ulcer were seen, of whom 129 (24%) had giant gastric ulcer. Giant gastric ulcer patients were significantly older (p < 0.05) than patients with smaller ulcers and had more aggressive disease, reflected by a higher incidence of bleeding, anorexia, weight loss, and emergency admission. More giant gastric ulcers were located in the body of the stomach and a higher proportion looked malignant. Four of 129 patients died immediately (bleed n = 3, unrelated cause n = 1), 15 had urgent surgery (bleed n = 11, perforation n = 2, suspected cancer n = 2) and 110 were treated medically, mainly with cimetidine 1 g daily. Healing occurred in 97 of 110 (88%), including 14 of 15 with refractory disease, i.e., healing took >3 months and/or needed cimetidine 2-3 g daily. Of the remaining 13 patients, six died (from unrelated causes), three had surgery for failed medical treatment, two defaulted, and two were still on treatment (one with refractory ulcer). Refractoriness was more common in patients with associated major medical illness (42% vs 12%, p < 0.01) or with giant gastric ulcers that looked malignant although they were benign (53% vs 21%, p < 0.01). Relapse off treatment was higher (13 of 26) than on maintenance treatment with cimetidine 0.4-2 g daily (14 of 70). Complications occurred in six patients: four off treatment and two on maintenance treatment. Only two giant gastric ulcers finally proved to be malignant. Of the 129 patients, 47 (36%) died, 14 within 3 months (two from bleeding, three postoperatively, nine from unrelated causes) and 33 later (two with gastric cancer and 31 from unrelated causes).
  
  
  CONCLUSIONS
  Giant gastric ulcer is uncommon. Patients are more seriously ill than those with smaller ulcers. Most giant gastric ulcers heal with histamine H2-receptor antagonist treatment. The condition is a marker of poor general health, reflected by the high long term mortality.
