[Isolated iliac aneurysm].

The incidence of isolated iliac artery aneurysm is 1-2% of that of abdominal aortic aneurysms. The natural history is of gradual enlargement, with rupture the most common clinical presentation. The signs and symptoms of such an aneurysm are influenced by its concealed location within the bony pelvis. Awareness of these special characteristics improves the chances of early diagnosis and proper surgical treatment before possible rupture. We report 2 cases which demonstrate the spectrum of the clinical presentation.

[Total colectomy and mucosal proctectomy with J-pouch anal anastomosis for ulcerative colitis and familial colonic polyposis].

Total colectomy and mucosal proctectomy with ileal pouch-anal anastomosis is the accepted surgical procedure for ulcerative colitis and familial polyposis of the colon. During 1981-1990, 25 patients with ulcerative colitis or familial polyposis underwent this operation in our department. In the majority a J-pouch was performed. In the early years, an 8 cm rectal muscular sleeve was left. In later cases, in accordance with opinions expressed in the medical literature, the length of the sleeve was shortened to about 3 cm. We present the functional results and the early and late complications on follow-up of up to 10 years (mean 3.5 years). Although this operation is not the ideal solution, it is better than the alternatives and is the surgical procedure of choice.

[Subtotal cholecystectomy: an emergency procedure for the difficult gallbladder and high-risk patient].

Emergency cholecystectomy in high-risk patients is still associated with significant morbidity and mortality. Occasionally technical difficulties and bleeding diathesis are complicating factors. Our prospective experience with subtotal cholecystectomy in 23 consecutive patients is presented. All presented as increased surgical risks (APACHE II above 10) and suffered from acute cholecystitis with empyema or perforation. 1 patient died (4.4%), but overall, surgical complications were minimal. We conclude that subtotal cholecystectomy combines the advantages of cholecystectomy and cholecystostomy. We believe that this short, simple and safe procedure is a logical choice for emergency situations in critically ill patients.

Contemporary management of the appendiceal mass.

An appendiceal mass is the end result of a walled-off appendiceal perforation and represents a pathological spectrum ranging from phlegmon to abscess. Over the past decade, improved imaging and interventional radiological techniques have allowed a more accurate definition of pathology and thus a more specific and less invasive management than was previously possible. A management policy should be possible that allows over 80 per cent of patients presenting with an appendiceal mass to be safely spared an open operation.

Hypertonic saline infusion in hemorrhagic shock treated by military antishock trousers (MAST) in awake sheep.

OBJECTIVES: To determine the effect of military antishock trousers (MAST) combined with hypertonic saline in controlled hemorrhagic shock in an awake sheep model. DESIGN: Prospective, randomized, controlled study. SETTING: University research laboratory. SUBJECTS: Healthy adult sheep (21 to 33.5 kg) were studied in four experimental groups. INTERVENTIONS: Sheep underwent cannulation of the jugular vein and the carotid artery. An indwelling catheter was also inserted into their bladders. Mean arterial, pulmonary arterial, pulmonary artery occlusion, and central venous pressures, cardiac and stroke volume indices, systemic and pulmonary vascular resistances, PaO2 and PaCO2, and serum lactate and hemoglobin concentrations were measured at baseline, after induction of hemorrhagic shock, and subsequently during resuscitative treatments of normal saline, MAST, hypertonic saline, and the combination of MAST and hypertonic saline. MEASUREMENTS: Controlled hemorrhagic shock was induced by arterial bleeding of 40 mL/kg in all animals. The sheep were randomized into four groups. In group 1 (n = 5), controlled hemorrhagic shock was treated by 5 mL/kg sodium chloride 0.9% (isotonic saline). In group 2 (n = 6), controlled hemorrhagic shock was treated by 5 mL/kg sodium chloride 7.5% (hypertonic saline). In group 3 (n = 5), controlled hemorrhagic shock was treated by MAST inflated to 40 mm Hg followed by 5 mL/kg sodium chloride 0.9%. In group 4, controlled hemorrhagic shock was treated by MAST (40 mm Hg) followed by 5 mL/kg of hypertonic saline. MAIN RESULTS: Arterial bleeding was followed by significant decreases in mean arterial pressure (87 +/- 1 to 41 +/- 4 mm Hg; p < .001), cardiac index (4.6 +/- 0.4 to 2.0 +/- 0.2 L/min/m2; p < .001), and urine output (102 +/- 30 to 13.0 +/- 7 mL/hr; p < .001), and an increase in systemic vascular resistance (1517 +/- 130 to 2601 +/- 370 dyne.sec/cm5; p < .001). MAST inflation in group 3 increased systemic vascular resistance to 3018 +/- 399 dyne.sec/cm5 (p < .05) and mean arterial pressure to 79 +/- 5 mm Hg (p < .05), while cardiac index, urine output, and lactate concentration remained unchanged. Infusion of hypertonic saline after MAST inflation (group 4) resulted in an increase in mean arterial pressure to 99 +/- 4 mm Hg (p < .001), an increase in cardiac index to 4.1 +/- 0.4 L/min/m2 (p < .001), an increase in urine output to 221 +/- 93 mL/hr (p < .001), and a decrease in systemic vascular resistance to 1847 +/- 175 dyne.sec/cm5 (p < .005). CONCLUSIONS: In hemorrhagic shock, the combination of MAST and hypertonic saline increases mean arterial pressure, improves cardiac output and tissue perfusion during the application of MAST, and also prolongs for > 2 hrs the short beneficial effect of hypertonic saline on mean arterial pressure.

Infected peri-pancreatic necrosis causing gallbladder necrosis by direct extension.

Acute acalculous cholecystitis may develop in patients suffering from necrotizing pancreatitis. Conversely, acute pancreatitis may complicate acute gallbladder disease. We present a case that lends support to the existence of another possibility: gallbladder necrosis caused by direct extension of the necrotizing pancreatitic process.

Problems in the surgical management of sclerosing encapsulating peritonitis.

Sclerosing encapsulating peritonitis (SEP) is a rare complication of chronic ambulatory peritoneal dialysis. Although commonly involving the small bowel and associated with severe surgical complications, this entity has almost never been mentioned in the surgical literature. We report here another case of severe SEP and briefly discuss its surgical implications.
