The results of extended deep femoral angioplasty (EDFA) have been alaysed for 74 legs in 72 patients. In 69 per cent a femoropopliteal bypass would have been possible, so DEFA is considered here as an alternative operation. The success rate was 66-9 per cent, the failure rate 25-6 per cent and no effect was achieved in 7-5 per cent. Diabetes adversely affected the results. Of the failures, 45 per cent were diabetic, while the incidence of diabetes was only 14 per cent in the group where the operation was successful. The long term results of the operation were reasonable, 75 per cent being successful for 10-39 months. Age had no bearing on success or failure. The effects of EDFA were most dramatic on intermittent claudication. In 52 per cent it was abolished and in 92 per cent claudication distance was increased to over 200 yards. Good results were achieved after failed lumbar sympathectomy and failed femoropopliteal bypass. Successful results of EDFA could be predicted best by inspection of angiograms. Success or failure could have been predicted from the state of the run-off in 81 per cent of the cases. Claudication and rest pain were the most relieved by EDFA, followed by isachaemic ulceration of the leg. Gangrene of digits was helped but less than had been hoped. We conclude that the indications for femoropopliteal bypass are limited to cases of digital gangrene where angiography shows that bypass is possible or where an EDFA operation has failed.

The typical patient with diabetes mellitus seen at major hospitals in Papua New Guinea between 1974 and 1977 had florid symptoms, a very high blood glucose, was non-obese and non-ketotic and, frequently had neuropathy and proteinuria. In 25% hypertension was present which was significantly more common in the presence of proteinuria. Diagnosis was often delayed by failure to test urine for glucose and treatment was usually ineffective so that coma, usually non-ketotic, severe infections and gangrene occurred frequently. Although not as common as in other South Pacific countries, diabetes is increasing in Papua New Guinea. The provision of simple adequate facilities to test urine for glucose in all hospitals and the establishment of diabetic out-patient clinics in major centres to instruct both patients and other health workers are essential to improve treatment and reduce mortality and morbidity.

Forty patients (including 37 juvenile diabetic patients) with insulin-dependent diabetes mellitus and end-stage renal failure received 42 renal allografts during the interval from June 1970 to December 1975. Of the 30 patients who are alive (between six and 72 months after transplantation; average, 29 months), 19 have been fully rehabilitated. Gangrene of peripheral extremities occurred in 30% of the survivors. The use of "pretreated" cadaveric kidneys in the diabetic patient may become an attractive alternative to grafts from living related donors. Renal transplantation with living related and pretreated cadaveric donor kidneys is the treatment of choice and is superior to dialysis in the insulin-dependent diabetic patient with end-stage renal disease.

Of the complications of diabetes mellitus, none is more devastating than gangrene of the foot and the threat of leg amputation. The pathophysiology of vascular insufficiency, neurotrophic changes, and infection leading to this gangrene have been reviewed. Based on this pathophysiology, an approach for conservative surgery of the diabetic foot has been outlined. Using known principles of wound healing and the management of soft tissue infection, obviously necrotic or infected tissue is debrided and the wound managed conservatively. The use of debriding adjuncts such as the pulsating jet lavage, topical antibacterials, and biologic dressings are suggested to control the infection so that the wounds can be closed with either skin grafts or local flaps. This method can result in salvage of many feet and the maintenance of biped ambulation since the outlook for the diabetic with a major amputation is markedly different from the nondiabetic amputee.

Present methods of management of juvenile-onset diabetes mellitus do not prevent serious and debilitating complications affecting multiple organ systems. In an effort to reverse advanced forms of these complications, segmental transplantation of the pancreas has been performed on 10 patients, seven of whom simultaneously or subsequently received renal transplants. Long periods of normoglycemia (two to four and one-half years) were achieved in two patients who also maintained transplant kidney function. The course of these two patients is described to illustrate the possible value and limitations of the procedure. These patients had normal blood glucose levels, exhibited repeated normal intravenous glucose tolerance curves, and had repeated normal endogenous insulin levels. Their courses were characterized by (1) absence of problems related to pancreatic exocrine secretions into the bladder; (2) stable eye changes despite some episodes of hemorrhage from preexisting retinopathy; (3) vascular complications, including stroke and gangrene of extremities necessitating amputation despite successful femoropopliteal bypass grafting; (4) peripheral neuropathy; and (5) repeated infections. Both patients succumbed to vascular complications. Thus, pancreatic transplantation can maintain blood glucose and insulin at normal levels for extended periods of time. However, it does not reverse such complications as advanced retinopathy or atherosclerosis. Since the procedure may have value in preventing progression of these complications, it should be evaluated in patients with less advanced complications of diabetes.

One hundred patients, 111 limbs, with gangrene of the lower extremity were initially treated with lumbar sympathectomy. Lumbar sympathectomy appears to be most beneficial in the management of gangrene of the toe with a limb salvage rate of 75 per cent. The best results were seen when only one toe, not the big toe, was involved. Limb salvage dropped to 38 per cent for gangrene of the foot, and with gangrene of the leg, lumbar sympathectomy had no affect. The presence of diabetes had no affect on limb salvage for gangrene of the toe but did have an apparent affect on limb salvage for gangrene of the foot. Sympathectomy appeared to aid in stump healing, with 77 per cent of the amputations done not requiring revision to a higher level. Results of our experience appear to indicate that, for patients presenting with gangrene of the toes or forefoot who are not candidates for reconstructive arterial procedures, lumbar sympathectomy as an initial operative procedure should be given serious consideration.

During the years 1967-1976, bilateral lumbar sympathectomy was performed in 241 patients with arteriosclerotic occlusions. A questionnaire was completed by 137 patients. Of the total, 68% seem to have improved in some way postoperatively. The material was analyzed with regard to age, sex, diabetes and regarding the effects on pregangrene, established gangrene, amputation, claudication and skin temperature. The operative mortality was 2.1% and postoperative complications were few. Bilateral operation in one stage does not give a higher postoperative mortality than unilateral procedures. Postoperative side-effects, such as neuritic pains, sexual and urological dysfunctions, are considered. Bilateral lumbar sympathectomy still seems to be an alternative procedure, which may be offered some patients with marginal peripheral circulation, when reconstructive arterial surgery is not feasible.

One hundred and eighty-three conservative amputations of some part of the foot in 161 patients with gangrene from diabetes or arteriosclerosis have been studied retrospectively. They constituted 48 per cent of all amputations in one orthopaedic service over a period of twelve years, during which the minimal feasible procedure was always chosen. Sixty per cent healed soundly, but in over a third of these cases at least one revision to a higher level on the foot had been required. Factors that significantly influenced the outcome of the initial operation were the level of amputation, the age of the patient, the interval between the onset of gangrene and operation, anaemia and pyrexia.

Over a period of 11 1/2 years, 140 patients were operated on for aortoiliac disease; 81 had coexisting superficial femoral artery occlusions (combined segment disease). Patients with combined segment disease were older, had twice the incidence of diabetes, and significantly more rest pain and gangrene on presentation. Aortic bifurcation grafts were placed in 114 patients. Relief of rest pain and threatened gangrene was uniformly good. However, relief of claudication was significantly poorer in patients with combined segment disease. There were 11 "late" thrombotic graft occlusions. Six grafts with distal anastamoses to the external iliacs failed because of limb outflow problems, while five grafts to the common femoral position exhibited more diffuse problems. Late graft failures were due to progression of disease and not problems intrinsic to the grafts. Cumulative patency rates were 98.0% at one year and 94.6% at three years.

Two patients developed persistent ulcers on the trunk after cutaneous surgery. Both had "chemical" diabetes mellitus. Bacteriologic and histopathologic studies of the ulcers were not revealing of cause. The characteristics of the ulcers are described, and are contrasted with typical lesions of pyoderma gangrenosum and Meleney's postoperative progressive synergistic bacterial gangrene. We believe these patients had variant lesions of pyoderma gangrenosum.
