Background/Aims:
Recent pathological study demonstrated that extended lymphadenectomy is not always necessary for patients with early gastric cancer.
Methodology:
Twenty-eight patients underwent pylorus-preserving gastrectomy. The clinicopathological findings of patients with pylorus-preserving gastrectomy were compared to those of 58 patients with conventional distal gastrectomy.
Results:
There were no significant differences in surgical duration, blood loss, blood chemistry, food intake, and body weight loss. Regarding abdominal symptoms, early dumping syndrome was significantly higher in distal gastrectomy than in pylorus-preserving gastrectomy (35.6% vs. 12.0%, p<0.05). Remnant gastritis was also significantly higher in distal gastrectomy (57.1% vs. 27.7%, p<0.05). However, food residue tended to be more frequently seen in pylorus-preserving gastrectomy (33.3% vs. 61.1%, p=0.052). Based on questionnaire results, the rate of patient satisfaction with their surgical outcome tended to be lower in pylorus-preserving gastrectomy than in distal gastrectomy (84.0% vs. 95.6%, p=0.098). The tendency was more pronounced in patients over 70 years old (77.8% vs. 100%, p=0.065).
Conclusions:
Pylorus-preserving gastrectomy is superior to conventional distal gastrectomy in the prevention of dumping syndrome and reflux gastritis. However, since delayed emptying is frequently seen post pylorus-preserving gastrectomy, this procedure is not recommended for older patients under simplistic indications.
