Abstract
AIM: To investigate and clarify the effect of vagus on gallbladder motility through a comparative study.
METHODS: Twenty-three hepatocirrhosis patients with portal hypertension were included in this study. In Hassab operation group, the anterior and posterior trunk of vagus were surgically excised (H, n = 18); In vena coronaria ventriculi embolization group, the vena coronaria ventriculi bole was ligated and injected TH adhesive (8 mL) after splenectomy (VCE, n = 5). Before operation and 10 d after operation, 99mTc-labeled diethyl acetyl acid anilide iminodiacetic acid (99mTc-EHIDA, 185 MBq) was administered intravenously to the patients, and then scintigraphic method was used to assess the motor function of gallbladder. The index including radiocounting 30 min after injected 99mTc-EHIDA (GBRC 30min), emptying fraction (GBEF), emptying period (GBEP), emptying rate (GBER), latent period (GBLP), latent period radiocounting increment (GBLI) and latent period radiocounting increment rate (GBLR) were analyzed.
RESULTS: GBRC 30 min in H group was significantly lower after operation than that before operation (74.8 ± 66.9 vs 155.7 ± 72.9,P < 0.05); GBLP was very short in pre-operation, and GBLP prolonged significantly after operation (13.36 ± 5.92 vs 2.24 ± 1.48, P < 0.01); the gallbladder radiocounting increased gradually during GBLP; the GBLI and GBLP level were very low before operation, but the GBLI and GBLP increased significantly after operation (79.5 ± 56.3 vs 9.2 ± 11.7, 113.4 ± 49.5 vs 7.6 ± 10.8, P < 0.01); GBEP shortened significantly after operation (18.5 ± 6.3 vs 24.1 ± 6.4, P < 0.05); GBEF and GBER decreased obviously after operation (13.1 ± 5.4 vs 32.3 ± 16.3, 0.7 ± 0.3 vs 1.4 ± 0.8, P < 0.01). The preceding parameters in VCE group had no significant difference before and after operation (P > 0.05).
CONCLUSION: The gallbladder tension weakens obviously in interdigestive phase after the vagus is excised; the gallbladder contraction delays, and the motor function weakens obviously after meals.
