[Postoperative course after laparoscopic surgery of the upper abdomen].
Laparoscopic techniques in general surgery have become a widely accepted method, especially for treatment of symptomatic gallstone disease. Many reports have investigated the indications, contraindications, equipment, techniques and outcome of laparoscopic procedures. However, as yet, relatively few studies have discussed the problems concerning patient's monitoring and care during the postoperative course. In the present paper, the authors review the pertinent literature analyzing the management of the postoperative period after laparoscopic surgery of the upper abdomen. Obviously, most data have regarded cholecystectomy, that is the most frequent procedure. Surgical laparoscopists have utilized knowledge deriving from gynecological experience, but these procedures are generally short and performed on young, otherwise healthy female patients. On the contrary, laparoscopic digestive surgery shows both gastrointestinal and peculiar general problems. These procedures are frequently performed on older patients who may have pre-existing diseases and require longer periods of peritoneal insufflation. During surgery of the upper abdomen, the pneumoperitoneum and the patient's operative position produce haemodynamic and respiratory changes coupled with acid-base disturbances. Intraabdominal hypertension causes a venous stasis along the inferior vena caval territory that can lead to a decrease in cardiac preload and in cardiac output. Usually, a compensatory increase in peripheral vascular resistance ensures normal or mildly high values of arterial tension. Furthermore, a hypercapnia and a mild mixed acidosis can develop as a result of the concomitance of different pathogenetic factors.(ABSTRACT TRUNCATED AT 250 WORDS)
