Transitory elevation of serum amylase levels after restorative proctocolectomy.
The incidence of postoperative hyperamylasaemia was evaluated in 70 patients who underwent staged restorative proctocolectomy. On the 14th postoperative day, 27 of 70 patients after total colectomy showed hyperamylasaemia, and the serum amylase returned to normal on the 30th postoperative day. Three out of 37 after ileoanal anastomosis and 8 out of 70 after stoma closure showed elevation of serum amylase postoperatively. Total colectomy might have a possible role in the postoperative increase of serum amylase. None of these patients had any obvious clinical evidence of postoperative pancreatitis. In 7 patients showing significant elevation of serum amylase levels (over 1000 IU), this was due predominantly to the pancreatic isoenzyme. This transitory elevation of serum amylase did not seem to be altered by the administration of therapeutic agents for pancreatitis. These observations suggest that postoperative hyperamylasaemia without clinical evidence of pancreatitis is very common after total colectomy, and that postoperative hyperamylasaemia itself does not necessarily require treatment.
