After gastro-intestinal operations wound infection is usually caused by the inoculation of bacteria present within the intestinal tract into the incision during the surgical procedure. In theory, wound sepsis may be minimized by the following methods: (a) avoiding intestinal contamination of the incision; (b) altering the normal flora of the intestinal tract by adding oral antimicrobials to bowel preparation; (c) using topical or systemic prophylactic antibiotic administration for certain high-risk patients. The relative importance of these methods of prophylaxis is described.

Forty-two patients with idiopathic megacolon who were seen at St Mark's Hospital over an 18-year period are reviewed with regard to presentation, investigation and management. The differential diagnosis is discussed with particular reference to Hirschsprung's disease. ⋯ The indications for surgical intervention in 14 patients are reviewed. The results following subtotal colectomy were better than following a localized sigmoid resection.

The long term results of profundaplasty in the treatment of femoropopliteal arterial occlusion have been reviewed. Fifty patients have been studied with a mean follow-up period of 4 years (range 6 months to 8 years). Intermittent claudication was abolished or substantially improved in 5 of the 25 cases (20 percent); rest pain was relieved in 10 of the 25 cases (40 per cent), the remainder requiring a major amputation. ⋯ The state of the distal 'run-off' and the degree of preoperative profunda stenosis appeared to have little influence on the clinical outcome. After operation pedal pulses were restored in 16 per cent of those presenting with claudication. Profundaplasty was without significant effect on the ankle systolic pressure index both in patients with claudication and those with rest pain.

A series of 45 patients with advanced occlusive arterial disease of the femoropopliteal segment underwent profundaplasty as the sole operative procedure. The value of this technique as a salvage procedure for the severely ischaemic limb is discussed.
