Differential bore sheath breast biopsy--a pilot study of a new technique.

The increasing requirement for core biopsy in the diagnosis of early breast disease puts additional demands on radiologists' time and expertise. We present a new approach to percutaneous breast biopsy of impalpable lesions with core biopsy and simultaneous hook wire localization. The technique allows accurate localization of breast lesions and is unique in that it facilitates simultaneous hook wire localization. Percutaneous biopsy by this method was accurate in 9 of 11 patients.

Rectal strictures following abdominal aortic aneurysm surgery.

Rectal stricture formation is a rare complication of aortic aneurysm repair. Two case are described here. A combination of hypotension, a compromised internal iliac circulation and poor collateral supply following inferior mesenteric artery ligation can result in acute ischaemic proctitis--an infrequently described clinical entity. Ulceration and necrosis are the sequelae of prolonged ischaemia and fibrous stricture formation may result. One patient responded to dilatation and posterior mid-rectal myotomy; the other failed to respond to conservative measures and eventually had an end colostomy fashioned following intractable symptoms.

Short communication: Prospective assessment of a new graduated hookwire for the localization of impalpable breast lesions.

The benefits of the addition of site specific variable graduations to a conventional mammographic localizing wire were assessed in a prospective multidistrict study. Six surgeons and five radiologists localized lesions in 31 patients in three District General Hospitals. The advantages of the graduated wire were shown to be greater ease and accuracy of radiological localization with easier surgical excision and a smaller resected breast specimen.

Randomised study of sterile versus non-sterile urethral catheterisation.

Indwelling urethral catheters are the most common cause of urinary tract infections (UTI), yet there is no direct evidence that technique of catheter insertion affects this. In a prospective study, 156 patients underwent preoperative urethral catheterisation, randomly allocated to 'sterile' or 'clean/non-sterile' technique groups. There was no statistical difference between the two groups with respect to the incidence of UTI. There was a considerable cost difference between the two groups, the 'sterile' method being over twice as expensive as the 'clean' method. Strict sterility is not necessary in preoperative short-term urethral catheterisation and is more expensive and time consuming.

Thoracoabdominal total gastrectomy in the management of adenocarcinoma of the cardia. Is it worth it?

A series of 47 consecutive patients with adenocarcinoma of the gastric cardia presenting between 1982 and 1987 have been reviewed. Of these, 38 patients were eligible for surgery (operability rate of 80.85%) but only 25 patients underwent potentially curative resection (resection rate of 65.7%). The disease was extensive at the time of operation, with only two patients (8%) having node negative tumours. The mean hospital stay for patients undergoing resection was 21 days. There were 15 major complications in 10 patients undergoing resection, but a zero 30-day mortality rate. The prognosis of those patients undergoing radical resection remains dismal. No patient survived longer than 30 months, 80% were dead within 1 year. Tumour recurrence and metastases were documented in 13 patients (52%). In the unresectable group there were two deaths from intubation (9%). The mean hospital stay for this group of patients was 12 days. The mean duration of survival in the group was 5.4 months, 70% of patients dying within 6 months and 95% dead within 1 year. The value of radical surgery in patients with adenocarcinoma of the gastric cardia is questioned.

Inflammatory abdominal aortic aneurysms.

Inflammatory abdominal aortic aneurysms account for 10% of all abdominal aortic aneurysms. They are characterized at operation by their thick fibrotic walls which adhere to adjacent structures; this may present major technical difficulties requiring a modified surgical approach. Because they respond to treatment with corticosteroids, their management is controversial.
