A prospective survey of patients presenting with abdominal aortic aneurysm.

OBJECTIVES: To define the presentation and management of patients presenting with abdominal aortic aneurysm (AAA) DESIGN AND SETTING: A prospective survey was carried out of all patients presenting to hospitals within the Oxford region. MATERIALS AND METHODS: Data were collected by one surgeon in each hospital. Full details were collected onto data sheets. RESULTS: One hundred and ninety patients presented, 141 electively, 46 with ruptured AAA and three with acute AAAs. In 53 patients presenting electively the aneurysm was small and surveillance started. Fifty-six patients underwent an operation, three patients died. Of 46 patients with a ruptured aneurysm 24 (52%) died. In 11 no operation was carried out and all of these patients died within 24 h. Operative mortality was 13 of 35 patients (37%). More patients with a ruptured AAA were transferred to the teaching hospital compared with a district general hospital (p < 0.05). This was reflected in a lower operative mortality in the teaching hospital. CONCLUSIONS: The presentation of AAA in this study was approximately 15 per 100,000 population. Approximately one-third of patients presenting electively had small AAAs which required surveillance. A further third underwent an operation, the remaining patients being unfit. Approximately one-quarter of patients with a ruptured aneurysm did not undergo an operation. The operative mortality was 37%.

Which tests to choose when assessing hand function.

In an attempt to simplify the choice of the many tests available for the assessment of hand function nine commonly used tests assessing different modalities of hand function have been evaluated on a small group of patients. The tests are judged by how well they fulfil the criteria of being simple and quick to use, easy to replicate, relevant to the needs of the patient, objective and inexpensive to acquire. The five tests which most fulfilled these criteria have been used to form a concise and practical hand assessment pro forma.

Isolated tibial fractures in children.

In a review of 65 tibial fractures in children of which 25 were isolated and not associated with a fracture of the fibula, we found that isolated tibial fractures were not uncommon, and accounted for one-third of all tibial fractures in children under 11 years of age. They occur after two types of force, the most common being indirect violence involving a torsional injury. Isolated fractures unite easily without delayed union. Isolated transverse fractures never displace, and consequently do not require further radiographs following the initial check radiograph after the application of the plaster cast. In seven of the 25, the fracture was spiral or oblique and displacement into varus occurred for up to 2 weeks after the initial injury. These need careful follow-up, with weekly radiographs for the first 2 weeks. If the varus displacement is greater than 5 degrees we recommend manipulation in that period. After this time the fracture site is sticky, and manipulation will fail. Non-operative treatment is recommended for this fracture.

Neoplastic change in duplications of the alimentary tract.

Two cases of adenocarcinoma arising in sequestrated duplications of the bowel in adults are reported. The literature is reviewed and a tendency for duplications to present in early childhood is noted. Although relatively few of these anomalies persist into adult life 8 cases of neoplastic change have now been reported. The histological features of many of the duplications undergoing malignant degeneration suggest the presence of underlying epithelial instability in this condition. It is postulated that duplications of the large bowel have malignant potential.
