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