The measurement of pre-binding and post-binding tolerance pressure in binding pancreaticojejunostomy

Abstract

To evaluate the superiority of binding pancreaticojejunostomy (BPJ) and the appropriate degree of tightness of binding from the view of tolerance pressure of the anastomotic stoma. The clinical data of 24 patients with diseases of head of pancreas and duodenum who underwent binding pancreaticojejunostomy were analyzed. The tolerance pressure at the anastomotic stoma was measured before and after the binding. The pre-binding tolerance pressure at the anastomotic stoma ranged from 28 cm H2O to 65 cm H2O, with a median of 44 cm H2O. The post-binding tolerance pressure at the anastomotic stoma ranged from 75 cm H2O to 90 cm H2O, with a mean of 85 cm H2O, significantly higher than those before binding (P < 0.01). Binding greatly increases the tolerance pressure at the anastomotic stoma. The tolerance pressure adopted is appropriate.
