Arterial deepvenous difference of lipoproteins in skeletal muscle of patients in postoperative state: effects of medium chain triglyceride emulsion.

The effect of fat infusion with medium chain triglycerides (MCT) and long chain triglycerides (LCT) on serum lipoproteins before and after passage through the skeletal muscle was investigated with the forearm technic in eight patients after abdominal operation. All lipoprotein fractions were enriched with triglycerides and phospholipids from infused artificial fat particles with the consequence of significantly increased ratios of TG/PL and TG/apo B in VLDL, of TG/apo B in LDL and TG/apo A-I in HDL. Uptake and release of lipoprotein components by skeletal muscle are given by arterial-deepvenous differences considering the blood flow rates. The positive arterial-deepvenous difference of VLDL triglycerides after 4-hr infusion is interpreted as cleavage and uptake of infused MCT by the muscle. The release of LDL is more pronounced after the fat infusion than before, suggesting a degradation and enhanced catabolism of artificial fat particles. HDL release may be also a consequence of catabolism of artificial TG/PL-particles. These results indicate an uptake of MCT/LCT emulsion by the skeletal muscle.

Surgical intervention following fragmentation of gallstones by extracorporeal shock waves.

Five cases of surgical intervention following extracorporeal shock wave lithotripsy (ESWL) of gallbladder and bile duct stones are reported. This represents an incidence of surgical intervention in 1% of patients with gallbladder stones and in 9% of patients with common bile duct stones who underwent ESWL during a two-and-a-half-year investigation period. There was no mortality. In 2 patients with gallbladder stones and persistent colic after ESWL, elective cholecystectomy was performed. There was no evidence of macroscopic or microscopic damage or bleeding within the wall of the gallbladder. Furthermore, no damage to the liver, common bile duct, duodenum, or stomach was noted. ESWL was applied in 34 patients with common bile duct stones in whom endoscopic sphincterotomy and stone extraction had proved ineffective. Three (9%) of these patients required surgery. In 1 patient, a Dormia basket got stuck and the basket, together with the stone, were removed by choledochotomy. In a second patient, rupture of a juxtapapillary diverticulum occurred 10 days after ESWL and 2 days after endoscopic extraction of stone fragments. At laparotomy, the retroperitoneum was drained. In a third patient with gallbladder and common bile duct stones, acute cholecystitis developed after lithotripsy of common bile duct stones. Cholecystectomy was performed and a t-tube was inserted in the bile duct. In all patients, the postoperative course was uneventful. In our experience, ESWL is a safe procedure with no mortality and an infrequent need for surgical intervention.
