Abstract
AIMS
To evaluate association between duodenogastric reflux and early gastric mucosal changes before and after the cholecystectomy procedure.
MATERIALS AND METHODS
Patients were evaluated with preoperative and postoperative endoscopy and endoscopic biopsy. Demographic and clinical characteristics, histological parameters, presence of duodenogastric reflux, and Updated Sydney scores were noted.
RESULTS
A total of fifty patients who obeyed the follow-up were enrolled into the study. Median age of the patients was 43 years (range 25-84). Male-female ratio was 0.51 (17/33). Duodenogastric reflux % and Updated Sydney scores before and after cholecystectomy were 24 (48%) versus 39 (78%) and 2.38 ± 2.21 versus 3.46 ± 3.05, respectively (p = 0.001, p < 0.000). Mucosal inflammation degree showed significant increase in 15 (30%) patients, decrease in 7 (14%) patients and equality in 28 (56%) patients (p = 0.037). Neutrophil activation degree was significantly higher in 21 (42%) patients, lower in 5 (10%) patients after the surgery (p = 0.005). Postoperative glandular atrophy degree was also higher in 13 (26%) patients and equal in 37 (74%) patients (p = 0.001). Pre- and postoperative degree of intestinal metaplasia and H. pylori density did not any show significant difference (p = 0.157, p = 0.248, respectively).There were significant positive correlation between postoperative H. pylori infection and mucosal activity, inflammation, atrophy and intestinal metaplasia.
CONCLUSION
Cholecystectomy is a potent inducer of pathologic duodenogastric reflux. Early onset of duodenogastric reflux and underlying H. pylori gastritis cause early gastric mucosal injury following cholecystectomy procedure by interacting collectively.
