OBJECTIVETo find an inhibitor to reduce the volatilization of formalin.

METHODThe saturated solution of sodium hydrosulphite (SHS) was sprayed on the surface of the anatomy specimens, then the concentration of formaldehyde in the air was tested.

RESULTSThe concentration of formaldehyde in the air of SHS sprayed group [(3.10 +/- 1.22) mg/m3] was significantly lower than that of the control group [(8.36 +/- 4.11) mg/m3, P < 0.01].

CONCLUSIONSHS may be a volatilization inhibitor for formalin, which could reduce the concentration of formaldehyde in the air.

At present,vascular intervention and surgery are the main methods for the treatment of pancreatic fistula with bleeding after pancreaticoduodenectomy,but these treatment methods have certain drawbacks,such as the complications of pancreatic fistula,bleeding,and abdominal infection after surgical treatment,and interventional treatment sometimes fails to identify the bleeding site.This article reports a case of complex pancreatic fistula with massive venous hemorrhage after pancreaticoduodenectomy treated with Foley catheter balloon compression through the drainage tube sinus.Bleeding was arrested and gastrointestinal fistula was cured after catheter balloon compression and effective drainage,with no complications such as pancreatic pseudocyst,intestinal ischemia,and portal hypertension.
