Abstract:
OBJECTIVETo study the expressions and the significance of interleukin-8 (IL-8) and cyclooxygenase-2 (COX-2) in the remnant stomach.
METHODSFifty-eight patients with gastrectomy were examined by upper gastrointestinal endoscopy. Two biopsy specimens were obtained from the stoma and the upper corpus gastric mucosa in the remnant stomach. mRNA was extracted from biopsy specimens to measure the IL-8 and COX-2 gene mRNA levels by real-time PCR method.
RESULTSIL-8 and COX-2 levels were higher in stoma than in corpus, IL-8 levels in BI anastomosis were significantly higher in stoma than in corpus (P< 0.05). In Hp-negative patients, IL-8 and COX-2 levels in stoma were significantly higher in BII anastomosis than in BI anastomosis (P < 0.05). In Hp-positive patients, IL-8 and COX-2 levels in stoma showed no significant differences between BII anastomosis and BI anastomosis. In corpus, IL-8 and COX-2 levels in Hp-positive patients were significantly higher than those in Hp-negative patients, (P < 0.05), including in BI anastomosis and in BII anastomosis.
CONCLUSIONSThe risk of the secondary stomach carcinogenesis in stoma after distal gastrectomy is higher than that in corpus; The types of anastomosis may influence the risk for the secondary stomach carcinogenesis in the remnant stomach mucosa.
