Distal small bowel motility and lipid absorption in patients following abdominal aortic aneurysm repair surgery.

Aim: To investigate distal small bowel motility and lipid absorption in patients following elective abdominal aortic aneurysm (AAA) repair surgery.

Methods: Nine patients (aged 35-78 years; body mass index (BMI) range: 23-36 kg/m(2)) post-surgery for AAA repair, and seven healthy control subjects (20-50 years; BMI range: 21-29 kg/m(2)) were studied. Continuous distal small bowel manometry was performed for up to 72 h, during periods of fasting and enteral feeding (Nutrison).

Small intestinal motor patterns in critically ill patients after major abdominal surgery.

Objectives: In patients who have had major surgery or trauma, early enteral feeding is safer and more effective than parenteral or nasogastric feeding but is frequently associated with diarrhea. Limited recordings have shown that the patterning of duodenal interdigestive motor activity is frequently abnormal after surgery or in patients who are critically ill. The aims of this study were to evaluate the effects of major abdominal surgery on small intestinal motility, and to elucidate the motor patterns that occur postoperatively in critically ill patients in response to enteral feeding.

Sporting 'groin strains': not always muscular!

A gluteal artery pseudoaneurysm presenting as a 'groin strain' following minor trauma is reported. Diagnosis was made by CT scan and arteriography. Treatment was with superselective catheterization and microcoil embolization.

Blunt injury to the subclavian artery.

This paper reports two cases of closed injury to the subclavian artery, one resulting from avulsion and the other from compression from a seat-belt. Diagnosis may be delayed because of the absence of both haemorrhage and distal ischaemia. The surgical approach may be via a standard supraclavicular incision, but frequently a combined cervicothoracic approach is necessary.

Intermittent sequential pneumatic compression of the legs and thromboembolism-deterrent stockings in the prevention of postoperative deep venous thrombosis.

One hundred fifty patients over the age of 30 who had undergone major abdominal operations were stratified according to the risk of deep venous thrombosis and randomized into three groups to receive different prophylactic regimens: group A, electrical calf stimulation; group B, low-dose subcutaneous heparin; group C, intermittent sequential compression and thromboembolism-deterrent (TED) stockings. All the patients were scanned with the 125I-fibrinogen test for the whole stay in hospital. The incidence of 125I-fibrinogen detected deep venous thrombi was 18% in group A, 9% in group B, and 4% in group C.
