A prospective study was carried out for 6 months to determine the efficacy of blood ordering routines for elective surgery. It was found that only 23% of procedures needed preoperative crossmatching of blood (transfusion index 'TI' greater than 0.5). There was an excessive over-ordering of blood for 77% of the operations (crossmatch/transfusion ratio greater than 2.5). In addition, the transfusion index for the latter group showed that there was no need to prepare blood preoperatively (TI less than 0.5). A transfusion tariff is worked out which abandons crossmatching for the majority of procedures (cholecystectomy, thyroidectomy and surgery for duodenal ulcer excluding gastrectomy). Instead a 'group and screen' policy is suggested.

Ten cases of necrotizing fasciitis are reviewed. Three patients died but only two of these deaths were due to uncontrolled septicaemia. All isolated organisms were sensitive to a combination of piperacillin and ampicillin which we now regard as the initial antibiotic combination of choice. Prompt and aggressive surgical debridement remains the cornerstone of management.

The effectiveness of two maneuvers, anal stretch (group 1) and sphincterotomy (group 2), were evaluated in reducing posthemorrhoidectomy pain. The study included 133 patients in group 1 and 125 patients in group 2. Immediate follow-up results showed that 18.4 percent of patients in group 2 required narcotic analgesics in the first 24 hours as compared with 100 percent of group 1 patients (P less than .01). Urinary retention developed in 4 percent of the patients in group 2 and 39 percent of the patients in group 1 (P less than .01). Pain associated with the first postoperative motion was severe in 96.2 percent of those in group 1 as compared with 6.4 percent of patients from group 2 (P less than .01). Moreover, long-term follow-up showed that 57.3 percent of group 1 patients continued to suffer from fecal soiling for ten weeks as compared with 6.4 percent in group 2 who suffered only 4.5 weeks (P less than .01). The routine performance of sphincterotomy through one of the hemorrhoidectomy wounds significantly reduced posthemorrhoidectomy pain and complications.

Exteriorized colon anastomosis is simple, avoids the inconvenience of colostomy and can be an alternative to routine colostomy. It is suitable where colostomy is socially unacceptable or the facilities and care is not available.
