Abstract
Objective: to determine the prevalence of Helicobacter pylori
infection in patients having undergone gastrectomy for nonneoplastic
disease who later developed gastric stump cancer.
Material and methods: retrospective study of all patients
with partial gastrectomy for non-malignant peptic disease who
were submitted to an endoscopic exploration between 1995 and
2001. A comparison was made of major clinical and histological
characteristics, and the presence of Helicobacter pylori among
patients with and without gastric cancer in the stomach remnant.
Results: a total of 73 patients were studied in this period. Fifteen
patients (20.5%) had remnant-stump gastric cancer. All but
one were adenocarcinomas (71% intestinal and 29% diffuse, respectively).
The average time between diagnosis of gastric cancer
and previous gastrectomy was 32 (14-48) years. There was a
higher detection rate of Helicobacter pylori in patients with cancer
in the gastric remnant (100 vs. 81.5%, respectively, p <
0.07). No relationship was seen between type of gastric reconstruction
(Billroth I or II) and rate of Helicobacter pylori detection.
Conclusions: Helicobacter pylori infection is frequent in patients
with previous gastrectomy for non-neoplastic disease. The
results of the study suggest that Helicobacter pylori infection may
play a role in gastric stump cancer.
