A retrospective review is presented of 496 children with a median age of 4 years (range 0-13 years) on whom a total of 527 hernia repairs were performed as out-patients. No wound infections were observed, and the rate of early surgical complications was 1.5 per cent. ⋯ Owing to the negligible infection rate and the low surgical complication and recurrence rates it is concluded that children with inguinal hernia would benefit from operation as out-patients, and that they should be operated on immediately after diagnosis, irrespective of age. Besides probably minimizing the children's psychological trauma, out-patient surgery provided considerable savings to the health service in the present study.

Medical records of all patients, from a defined population of 88,000 inhabitants, who underwent major lower limb amputation during 1980-82 were retrospectively scrutinized. The records showed 131 amputations were performed in 106 patients at the district hospital and 22 amputations on 17 patients at the local university hospital, referral centre, altogether 57 men and 66 women. This gave an amputation incidence of 46 per 10(5) inhabitants per year. ⋯ For patients who came from and eventually returned to their own homes the mean hospital stay amounted to 184 days (postoperative deaths excluded). After amputation 26 patients were trained to wear a prosthesis and 16 of these used the prosthesis 2 years after amputation. The present study underlines the need for prospective and parallel studies of vascular surgery and amputation as well as analyses of the risk factors involved in lower limb ischaemia in defined populations.

Successful islet allografts can be established in rats bearing long surviving renal allografts, without additional immunosuppression, when kidney and islet donor animals are of the same strain. The applicability of such a scheme to clinical practice has been investigated in a large animal model of diabetes: the pancreatectomized dog. ⋯ Three of the sequentially transplanted dogs had had no renal graft rejection episodes before islet transplantation, yet their islet grafts were all rejected within 19 days. In the pancreatectomized dog, prior donor specific renal transplantation has an adverse effect upon subsequent islet graft survival.

A retrospective study of patients having gastroenterostomies was undertaken to identify predictive factors for the development of postoperative delayed return of gastric emptying (DRGE). A total of 322 consecutive patients underwent 324 gastroenterostomies; 35 experienced delayed return of gastric emptying. Regression analysis demonstrated preoperative obstruction to be the most significant factor (P less than 0.001). ⋯ In all, 86 per cent of cases resolved spontaneously. Only one case of DRGE was found to have a mechanical cause. Most patients were supported by parenteral nutrition but, with a knowledge of the identified risk factors, more thought could be given to establishing a route for jejunal feeding at the time of surgery.
