61.   Peptic ulcer disease is a multifactorial inheritant disease.

62.   In addition, peptic ulcer disease represents a heterogeneous group of disorders attributable to a variety of genetic and environmental causes.

63.   Besides H pylori, aggressive factors are necessary for peptic ulcer pathogenesis.

64.   This study analysed gastric mucosal DNA by P-postlabelling in a series of patients who have had previous vagotomy for benign peptic ulcer disease.

65.   Large cohort studies have indicated that one such group consists of patients who have had previous vagotomy for benign peptic ulcer disease.

66.   Whatever the agent responsible, or its mode of action, this is another factor to be considered when selecting an operation for benign peptic ulcer disease.

67.   Fifteen peptic ulcer patients who were not part of any formal trial of treatment, were referred, chiefly by surgeons presumasbly to help choose the most appropriate operation.

68.   Efficacy of the heater probe in peptic ulcer with a non-bleeding visible vessel.

69.   A controlled, randomised study was performed to evaluate the efficacy of treatment with heater probe in the prevention of rebleeding from peptic ulcer with a non-bleeding visible vessel.

70.   These results suggest that the heater probe is an effective and safe procedure in the prevention of recurrent haemorrhage in peptic ulcer with a non-bleeding visible vessel.
