Abstract:
Objective To observe changes of hepatic hemodynamics and hepatic functional reserve after splenectomy and periesophagogastric devascularization. Methods From July 2006 to August 2007, thirty patients with portal hypertension caused by hepatitis B cirrhosis underwent splenectomy and periesophagogastric devascuiarization. The PVPG (portal venous pressure gradient) was measured by inductor continually during operation. The HAF (hepatic artery flow), PVF (portal venours flow) and hepatic arterial RI(resistant index) were measured with Doppler sonography. The EHBF(effective hepatic blood flow) and ICGR15 (indocyaninegreen retention rate at 15 minutes) were obtained respectively by indocyaninegreen clearance test before and after the operation. Results PVPG after laparotomy (19±4) mm Hg, ligating the splenic artery(14±4) mm Hg, splenectomy(14±3)mm Hg and periesophagogastric devascularization (12±4) mm Hg showed a tendency to decrease progressively. The PVF decreased [from (42±14) ml/s to (16±8) ml/s] and HAF increased in compensation after operation. The EHBF increased [from (0.48±0.10) L/min to (0.56±0.10) L/min], and the ICGR15 decreased (from 23%±8% to 18%±4%) postoperatively. Conclusion After splenectomy and periesophagogastric devascularization, the hepatic functional reserve improves at least in a short term notwithstanding the decrease of PVPG and PVF.
