The aims of our studies were: (1) to determine if the protein catabolic response after a major or moderate surgical trauma can be restrained by the administration of exogenous human growth hormone (hGH); (2) to determine if the administration of hGH can improve systemic host defenses, thus reducing the risk of infection, and (3) given that the postoperative(More)
The first purpose of the present prospective randomized study was to determine if the protein catabolic response after operation could be restrained by administration of hypocaloric parenteral nutrition (HPN) plus human growth hormone (hGH). Our second aim was to determine if the administration of hGH could improve the systemic host defenses, thereby(More)
The controversy about laparoscopy assisted colectomy for cancer is based on doubt about performing a radical resection and adequate histopathological staging. Therefore, we selected a group of patients who could profit from the accepted benefits of the technique, while avoiding its uncontrolled outcome. We operated on patients with colorectal cancer with(More)
The purpose of the present study was to determine whether the administration of a biosynthetic human growth hormone was capable of enhancing the efficacy of total parenteral nutrition. Patients (n = 38) who had undergone major gastrointestinal surgery were randomly divided into two groups. Group I (n = 20) treated only with PN, and Group II (n = 18) treated(More)
Convalescence after surgery is characterized by a period of fatigue (POF). If we assume that the POF syndrome has a multifactorial etiology, it is clear that the aim of therapeutic measures should be to reduce the response to surgical stress. The purpose of the present study was to determine if administering exogenous human growth hormone (hGH) can prevent(More)
Cysts of epithelial bodies are rare causes of hyperparathyroidism. Reported in this paper are 2 patients with clinical symptoms of hyperparathyroidism, high blood calcium levels and established hormones in their epithelial bodies. Cysts of epithelial bodies were diagnosed by means of angiography, computed tomography, and sonography. Various aetiological(More)
Moderate normovolemic hemodilution (MNH) is used in general surgery not only when major blood loss is anticipated but also as a prophylactic measure for the prevention of postoperative deep vein thrombosis. The hemodynamic effects of MNH (hematocrit value 27-29%) with dextran 70 as diluent were evaluated in 50 patients undergoing major surgery(More)
Treatment of hepatic echinococcosis remains a surgical problem not only in endemic countries. Between January 1983 and December 1999 a total of 29 patients underwent surgical treatment for hepatic hydatidosis at the Department of General Surgery at the University Hospital of Granada. The diagnosis was based on clinical criteria, serology, and imaging(More)
