ROTEM disagreed with SCTs and did not show the temporary hypocoagulability suggested by SCTs. Both ROTEM and SCTs showed no signs of hypercoagulability. Future studies involving ROTEM could help develop new guidelines for coagulation monitoring.

Open (OC) or laparoscopic (LC) cholecystectomy is considered a relative contraindication in patients with liver cirrhosis. The effect of LC and OC on the hepatic catabolic stress response was studied in patients with postnecrotic liver cirrhosis and chronic hepatitis to define the most suitable procedure from a metabolic point of view. Altogether 14 patients with cirrhosis and 14 with chronic hepatitis were randomized to LC or OC (n = 7 in each group). The increase in the functional hepatic nitrogen clearance (FHNC) was quantified. Changes in glucose, insulin, glucagon, cortisol, epinephrine, norepinephrine, and prostaglandin E(2) (PGE(2)) were observed. There was no difference in FHNC between LC and OC in any of the patients. Among cirrhotic patients OC caused a 132% increase in FHNC (p < 0.05) and among the hepatitis patients a 69% increase (p < 0.05). In contrast, there was no significant increase following LC in any of the patients. OC increased fasting glucose and insulin in the hepatitis patients (p < 0.01 and p < 0.001, respectively) and in the cirrhosis group (p < 0.01 and p < 0.05, respectively). Alanine stimulation increased glucose in hepatitis patients after OC (p < 0.05) and after LC (p < 0.01). Stimulated glucagon increased after OC in the hepatitis group (p < 0.05). During stimulation cortisol was higher following LC in hepatitis patients (p < 0.01) and cirrhotic patients (p < 0.05). Fasting PGE(2) was down-regulated after LC in hepatitis patients (p < 0.05) and cirrhotic patients (p < 0.01) and after OC in the hepatitis group (p < 0.001). FHNC is similar after LC and OC. Thus from a metabolic point of view, LC has no advantage over OC.
