Relationship between Gastric Stasis in the Remnant Stomach and Interdigestive Migrating Complex in Patients after Pylorus-Preserving Gastrectomy for Gastric Cancer

Abstract

Objectives: The demerit of pylorus-preserving gastrectomy (PPG) is gastric stasis in the remnant stomach (GSRS). We investigated the relationship between postgastrectomy disorder (PGD), especially GSRS, and interdigestive migrating complex (IMC) in PPG patients. Background: The cause of GSRS is still unknown. Therefore, we studied relationship between GSRS and IMC. Methods: 24 PPG patients (16 men and 8 women; mean, 61.2 years) were divided into groups A (12 patients without GSRS) and B (12 patients with GSRS). The relationship between GSRS and IMC was studied. Results: Length of the antral cuff (LAC) was significantly longer in group A than group B (P < 0.0001). IMC and appetite were significantly more common in group A than in group B (P = 0.0465, P = 0.0186, respectively). Postprandial abdominal fullness (PAF) was significantly more common in group B than in group A (P = 0.0061). Reflux esophagitis (RE) and body weight loss were found in group B more than in group A. Dumping syndrome was not found in either group. Endoscopic gastritis was found significantly more in group B than in group A (P = 0.0047). Conclusions: In PPG patients with a short LAC, GSRS may occur by the decrease of IMC occurrence.
