Correlation between the length of the pyloric cuff and postoperative evaluation after pylorus-preserving gastrectomy

Abstract

Background: Recent years have seen the preserved pyloric cuff being lengthened in pylorus-preserving gastrectomy for early gastric cancer. We performed clinical assessment of the symptoms after pylorus-preserving gastrectomy in patients treated at the National Cancer Center Hospital in Japan during the past 9 years.

Methods: Four hundred and fifty-six patients who had undergone pylorus-preserving gastrectomy and been followed up for at least 3 years were studied. We classified the patients into two groups according to the length of the pyloric cuff (group A, within 3.0 cm; group B, more than 3.0 cm). Medical records were reviewed for further histological and follow-up data. A questionnaire regarding dumping syndrome and gastric stasis was also completed by the patients.

Results: Our results showed no statistically significant differences in symptoms, such as dumping syndrome or emptying disturbances, between the two groups.

Conclusion: Our study revealed that the differences in several functions and symptom scales were not pronounced between the two groups. Regardless of the length of the pyloric cuff, pylorus-preserving gastrectomy can be utilized for the treatment of early gastric cancer even if the tumor is located proximal to the middle body.
