The records of 71 patients with the diagnosis of adenocarcinoma of the pancreas were reviewed. Seventeen patients were treated without surgery, 13 underwent exploratory laparotomy for diagnosis with no further palliative or curative operative procedure, six underwent pancreaticoduodenal resection, and 35 patients had a palliative gastric and/or biliary bypass procedure at initial operation. No preoperative signs or symptoms, routine laboratory tests, or radiologic evaluation were helpful as early diagnostic or prognostic indicators. Surgical mortality rates were not significantly different among the four groups; however, the survival time differences between the palliative group (4.8 mo) and the medically managed group (2.0 mo) was significant (p = 0.01 chi 2). Surgical morbidity did not differ significantly among the four groups of patients. The implications of these data in the treatment of patients with adenocarcinoma of the pancreas are discussed.

Measurement of mixed venous oxygen saturation (SvO2) may be helpful in the care of critically ill patients. Serial determinations of SvO2 give an index of the relationship between oxygen delivery and tissue oxygen consumption. Continuous monitoring of SvO2 is now readily available with the Shaw Oximetrix pulmonary artery catheter (Oximetrix Inc., Mountain View, CA). This system has provided useful information in the high risk cardiac surgery patient. Continuous monitoring of mixed venous saturation may be helpful in high risk or critically ill general and peripheral vascular surgery patients both in the intensive care unit and in the operating room. The following clinical report is presented to illustrate the usefulness of continuous SvO2 monitoring in a high risk vascular surgery patient.
