Evaluation of perioperative administration of methylprednisolone sodium succinate and urinary trypsin inhibitor for prevention of surgical stress.
The authors could confirm that the laparoscopy-assisted cholecystectomy (LAC) elicited less postoperative biological responses compared to the ordinary cholecystectomy under laparotomy (OCL), when granulocyte elastase (GE)-alpha1-protease inhibitor complex (GEcomplex), interleukin-6, pancreatic secretory trypsin inhibitor (PSTI) and alpha1-antitrypsin (alpha1-AT) were used as biological response markers. Perioperative administrations of methylprednisolone sodium succinate (MPSL: 10 mg/kg body weigh) or MPSL with urinary trypsin inhibitor (UTI) could suppress such postoperative reactions after OCL down to the levels after LAC, especially immediately after surgery. Preoperative MPSL followed by continuous infusion of UTI for 3 days exerted the most prominent suppressive effects on these markers compared to the effect of the preoperative MPSL alone as well as the preoperative administration of MPSL followed by UTI infusion for only one hour. Bolus administration of MPSL induced no lymphocytopenia. Decreased plasma level of alpha1-AT immediately after operation is thought to be due to consumption in binding to GE as well as other lysosomal enzymes, while production of rapid turn over proteins are still not accelerated in the liver. In early postoperative phase after administration of MPSL, administration of UTI was efficacious to prevent fluctuation of biological response markers. Clinical applications of these drugs might be approved especially for those patients with poor risk.
