OBJECTIVE To review the results of the different modalities of treatment of acute necrotizing pancreatitis that have been used by a single team during a 6-year period to assess the technique and indications of an endoscopic method of retroperitoneal drainage that is routinely performed for the management of peripancreatic necrosis. DESIGN AND SETTING(More)
The aim of this retrospective study was to evaluate the outcome and prognostic parameters of patients over 85 years of age undergoing major abdominal emergency surgery. The medical records of 45 consecutive patients aged over 85 years who underwent major abdominal emergency surgery between May 1999 and November 2001 were reviewed. The mean patient age was(More)
OBJECTIVES To evaluate the efficacy of arterial embolization (EMB) in the management of bleeding pancreatic pseudocysts or pseudoaneurysms and to assess the possible indication for secondary surgery. DESIGN Retrospective review with a mean follow-up of 60 months (range, 18-125 months). SETTING Tertiary care center, university hospital. PATIENTS The(More)
BACKGROUND Off-line calculation of the pulse pressure variation (PPV(ref)) has repeatedly been shown to be a reliable predictor of fluid responsiveness in mechanically ventilated patients. This study was designed to assess the ability of two algorithms for automated calculation of PPV (PPV(auto)) (Intellivue MP 70) and stroke volume variation (SVV(auto))(More)
OBJECTIVE To evaluate advantages and drawbacks of a controlled conservative management of patients with severe gastric caustic injuries. METHODS Among 40 patients with severe caustic gastric burns (> IIb), 28 with stade III lesions (mosaic necrosis: n = 10, extensive or circumferential necrosis: n = 18) were managed prospectively from 1990 to 1998.(More)
OBJECTIVE In 2003, asplenia had involved 250000 patients in France. These patients are at risk of severe infection, mostly with capsulated bacteria as pneumococci, meningococci and Haemophilus. The higher mortality and morbidity due to infection in asplenic patient led in June 2003 a French expert committee to propose preventive management based on(More)
Transcutaneous oximetry has been used to define the level of amputation in arteritic patients, with discrepant results. We have studied preoperative statix oximetry in 33 arteritic patients at the Leriche-Fontaine Stage IV, who underwent 36 amputations (thighs = 6, Legs+Symes = 14, transmetatarsal = 7, toes = 9). Oximetry included the measurement, at the(More)
We report on two cases of duodenocaval fistula. The first patient, a 73-year-old man, had sepsis and occult digestive bleeding. We diagnosed a fistula that resulted from a right nephrectomy and subsequent radiotherapy for a urothelial tumor 20 months earlier. The second patient, a 60-year-old woman, complained of right abdominal pain. A duodenocaval fistula(More)
We describe a case involving spontaneous retroperitoneal hematoma caused by rupture of an aneurysm of the right ovarian artery 4 days after delivery in a multiparous woman. Diagnosis was achieved by arteriography. Bleeding was stopped by embolization via selective arteriography. Hematoma was drained by lomboscopy. The pathophysiological mechanisms(More)
