The outcome of 145 patients undergoing Hartmann's resection between 1973 and 1989 has been reviewed. The mortality rate of the primary procedure was 8 per cent. Eighty patients proceeded to reanastomosis. Multifactorial analysis of these patients was undertaken to determine the risk involved. The interval between the primary and secondary procedures was found to be the most important factor. Six of 12 patients had clinical evidence of a leak when this interval was < 3 months, compared with seven of 28 for 3-6 months, and none of 40 when the second operation was delayed for > 6 months. All deaths (three patients) and clinical septicaemia (four) occurred in the two 'early' groups. All colovaginal fistulae (three patients) and strictures (three) were associated with stapled anastomoses. No association was found between the complication rate following reanastomosis and the initial pathology or grade of surgeon undertaking the secondary operation.
tumour size, larger cancers are compared with smaller ones and screen detected cancers may appear less aggressive simply because of their shorter biological age. However, our results indicate that screen detected breast carcinomas are significantly associated with several features associated with low malignant potential even after adjustment for their smaller size.
Antibiotic prophylaxis is not routinely given for nonimplant, clean operations, although this view has recently been challenged. We have conducted a randomized multicenter, double-blind prospective trial to compare co-amoxiclav with placebo in 619 patients undergoing open groin hernia repair. Altogether 563 (91%) patients fulfilled the protocol; 283 received co-amoxiclav and 280 placebo. There was no difference between the groups in the number of patients receiving local or general anesthetic, the type of repair performed, the use of a subcutaneous fat suture, the type of skin closure used, the use of wound analgesia, or the use of a wound drain. Patients were given a card to return to the hospital in the event of their wound discharging or their needing to see their general practitioner. All patients were reviewed at approximately 6 weeks after operation. Fifty (8.9%) patients sustained a wound infection, 25 in the co-amoxiclav group and 25 in the placebo group. We conclude that antibiotic prophylaxis is of no benefit to patients undergoing open groin hernia repair.
The assessment of malnutrition by simple methods was studied in 120 patients undergoing elective major abdominal surgery to determine which index was of the most value in predicting postoperative complications. Weight for height and weight loss were of little significant value; serum albumin less than 35 g/l was more significant (p less than 0.05) but predicted only a quarter of those patients who developed serious complications. Measurements of muscle stores by anthropometry (arm and forearm muscle circumference) predicted nearly half the patients (p less than 0.01). By far the most useful index was hand-grip dynamometry, which predicted 90% of those who developed complications (p less than 0.001). The incidence of serious complications was 6 times greater in those patients with a low grip strength. Hand-grip dynamometry appears to be a useful screening test of patients at risk, and a valuable additional test for nutritional assessment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
