Objective:
To determine the therapeutic effect of laparoscopic splenectomy, perisoph-agogastric devascularization, and endoscopic variceal ligation (EVL) on patients with portal hypertension.
Methods:
We randomly divided 105 patients into 3 groups: 40 had endoscopic band ligation (the ligation group), 35 had splenectomy and perisoph-agogastric devascularization (the laparotomy group), and the other 30 had laparoscopic splenectomy, perisoph-agogastric devascularization and endoscopic variceal ligation (the combination group). Blood samples were analyzed preoperatively and postoperatively on day 1,3,and 7,including alanine aminotransferase(ALT),aspartate aminotransferase(AST),total bilirubin(TBIL),and directed bilirubin(DBIL). The length of stay, blood loss, operation time, anal exhaust time, azygos vein diameter, blood flow velocity and blood flow, recurrence of esophageal varices and rehaemorrhagia were compared.
Results:
Between the combination group and the laparotomy group, the serum levels of TbIL and Dbil had difference on 1st postoperative day(P<0.05). AST had difference on 7th postoperative day(P<0.05). The length of stay, blood loss, operation time, and anal exhaust time had significant difference(P<0.05). Among the combination group, the laparotomy group and the ligation group, the azygos vein blood flow before and after the treatment, recurrence of esophageal varices and rehaemorrhagia had no difference(P<0.05).
Conclusion:
Laparoscopic splenectomy, perisoph-agogastric devascularization and endoscopic variceal ligation have less trauma, lower recurrence rate, fewer complications and rapid recovery, and may reduce the azygous vein blood flow. It can be used safely for portal hypertension.
