    Abstract:
    AIM: Following distal gastrectomy, carcinogenesis has been suggested to result from gastroduodenal reflux. In this study, surgical cases of gastric cancer arising after distal gastrectomy were analyzed clinico-pathologically and the possible link to reflux examined. PATIENTS: Thirty-two patients (24 males, 8 females; mean age, 68.7 years; age range, 33-84 years) with gastric cancer arising in the remnant stomach after gastrectomy (also known as gastric stump cancer) were included in this study. Patients were divided into two groups on the basis of the initial diagnosis (benign or malignant) prompting surgery, and distal gastrectomy reconstruction method (Billroth I or II). RESULTS: The interval between distal gastrectomy and detection of cancer in the remnant stomach of patients treated initially for a benign gastric condition vs. malignancy was 360+/-33.04 and 63+/-19.16 months (median+/-SE), respectively (p<0.0001). However, the benign and malignant groups did not differ significantly in the clinicopathological analysis of their stump cancers. All 10 patients in whom gastric cancer was diagnosed within five years of initial surgery had initially been surgically treated for malignancy. The interval between surgery and detection of gastric cancer in the Billroth I and Billroth II groups was 84+/-26.67 and 276+/-44.26 months (median+/-SE), respectively (p<0.01). In the remnant stomach, cancer tended to occur near the site of gastrojejunostomy in the Billroth II group (p=0.05). Helicobacter pylori infection was only detected histologically in four patients who had undergone Billroth I reconstructions after distal gastrectomy for malignancy. CONCLUSION: After distal gastrectomy, careful periodic endoscopic examination for microcarcinoma is required in patients, particularly in those who undergo surgery for malignancy, to maximize detection of gastric cancer.
