Two hundred eighty patients underwent laparoscopic cholecystectomy (LC) and were compared with 304 patients who underwent traditional "open" cholecystectomy (OC). Laparoscopic cholecystectomy was performed electively in 72.5% of cases and urgently in 27.5% of cases. Conversion from LC to OC was required in 14 patients (5%), six of whom required common bile(More)

PURPOSE Gastric intramucosal pH (pHi), a surrogate marker of tissue oxygenation, falls following abdominal aorta aneurysm (AAA) repair. We tested the hypothesis that volume replacement with a hydroxyethyl starch solution would result in better preserved splanchnic oxygenation than would volume replacement with crystalloid solutions.

STUDY OBJECTIVE To determine the incidence, clinical presentation, and risk factors of deep venous thrombosis (DVT) in a high-risk group of ICU patients receiving DVT prophylaxis. DESIGN A prospective cohort study. SETTING Two ICUs of a university-affiliated teaching hospital. PATIENTS Patients admitted to the ICUs within 48 h of hospitalization and(More)
Two hundred forty-four consecutive patients were reviewed who presented themselves over a ten-year period (1967 to 1977) with threatened limb loss secondary to arteriosclerosis involving the arteries supplying the lower extremities. Patients with claudication as the presenting complaint were not included. Primary amputation was performed in 14 patients(More)
OBJECTIVE To determine preoperative and perioperative risk factors for gastrointestinal (GI) complications following cardiac surgery. DESIGN A database including records of patients who underwent cardiac surgery was reviewed, with univariate analysis of several variables thought to be relevant to GI complications. Using a risk-adjusted model, preoperative(More)
OBJECTIVE To assess the validity of four severity-adjusted models to predict mortality following coronary artery bypass graft surgery by using an independent surgical database. DESIGN A prospective observational study wherein predicted mortality for each patient was obtained by using four different published severity-adjusted models. SETTING A(More)
