The stress response to laparoscopic cholecystectomy: investigation of endocrine parameters.

Laparoscopic cholecystectomy, as a typical example of minimal invasive surgery, is associated with low complication rates and minimal patient discomfort, and provides the same safety as conventional cholecystectomy. In the present prospective observational study, endocrine parameters as indicators for stress response were measured. We investigated 53 patient with laparoscopy cholecystectomy and 12 patients with conventional cholecystectomy.

Cardiac function in endocrine diseases: I. Acromegaly.

The aim of our echocardiographic study was to characterize cardiac function and anatomy of 14 acromegalics (A: 9 women, 5 men; mean age: 42.4 yrs) more closely. The duration of acromegaly in 4 of these patients was between 3 and 12 years; the disease was diagnosed for the first time in the other patients.

[Diagnosis and therapy of asymptomatic adrenal tumors].

Adrenal tumours had been discovered incidentally (since 1981) in 32 patients (23 females and nine males; mean age 54 [25-73] years) who had had computed tomography (CT) or ultrasonography for other reasons: none had a history or symptoms of such tumour. Tumours were bilateral in eight, right or left-sided in 12 each: all had been confirmed by CT. Average tumour size was 3 cm (1-9 cm).

The effect of sodium valproate in Cushing's disease, Nelson's syndrome and Addison's disease.

Unlabelled: We investigated the effect of sodium valproate on plasma ACTH and serum cortisol concentrations in different pathological states of ACTH hypersecretion. Five patients with pituitary dependent Cushing's syndrome, two patients with Nelson's syndrome and five patients with Addison's disease were studied. Neither a single dose nor long term administration of sodium valproate resulted in a significant decrease of plasma ACTH levels in patients with Cushing's disease and Nelson's syndrome.
