Bascom's operation for pilonidal sinus.

During 1985 in England and Wales, 7000 patients were treated for pilonidal disease with an average hospital stay of 5 days. The aim of this paper is to report our early experience with Bascom's operation for pilonidal sinus--a procedure relatively untried in the UK.

Surgical audit without autopsy: tales of the unexpected.

To establish our current practice and the potential value of the autopsy in general surgery, a retrospective review of general surgical autopsies was performed at one district general hospital from January 1989 to August 1991. There was considerable interconsultant variation in autopsy practice with a low 25% overall autopsy rate reflecting a low autopsy request rate. There were discrepancies between the clinical and pathological cause of death in 40 (63%) cases. There were important discrepancies which may have changed management in life in 18 (28%) autopsies, 7 (39%) of which were untreated visceral perforations. Autopsy is an important part of the surgical audit and will disclose considerable unsuspected pathology. Present autopsy rates are low and need to be improved. The unexpected finding of seven untreated visceral perforations requires further study.

Vascular access surgery: a 2-year study and comparison with the Permcath.

The results of a 2-year prospective study of primary and secondary vascular access surgery for haemodialysis have been compared with a retrospective study of central venous access via a flexible silicone catheter (Permcath). Cumulative patency for 61 primary fistulae in 57 patients was 64.8% at 1 year and 57.7% at 2 years. The patency of 55 secondary procedures in 43 patients was 48.1% at 1 and 2 years. Cumulative survival of 64 Permcaths inserted into 51 patients was 74% at 1 year and 43% at 2 years. Surgical complications included explorations for bleeding (2), haematomas (4), swollen arms (4), and inadequately dilated veins (4). Permcath complications included explorations for bleeding (3) and a temporary recurrent laryngeal nerve palsy (1). Exit site infection and septicaemia rates were 4.95 and 3.36 per 1000 catheter days respectively, but 20.6% of septicaemic episodes occurred in a patient who refused catheter removal. For haemodialysis, the Permcath is comparable with secondary vascular access. The Permcath may have a primary access role in patients with limited life expectancy.

Endothelial cell seeding.

Endothelial cell seeding is a technique that has developed over the past 15 years in response to the need for a high performance synthetic vascular graft. This review details our present knowledge of seeding and examines the various problems that have hampered its introduction into clinical practice.
