Patient satisfaction and symptom relief after anal dilatation.

Anal dilatation is used as a simple method of treatment and has been used for both anal fissure and haemorrhoids. This study examined longer-term results among a cohort of 162 patients, 132 of whom responded to a detailed questionnaire, an 82% response (66 patients were male; age range 17-75 years, median 42 years). Follow-up ranged from 16 months to 36 months (median 27 months) after anal dilatation (68 patients for fissure, 32 for haemorrhoids, and 32 for both). In the early months after dilatation, 83% had symptomatic improvement and 76% remained improved. Five (7%) patients with fissure and 11 with haemorrhoids (17%) required further hospital treatment, while 10% and 17%, respectively, had received further treatment from their general practitioners (GPs). Seventy-one percent said they would have a further anal dilation if symptoms recurred. There was no difference in results obtained by surgeons of different seniority. Complications--bleeding (29%) and difficulty controlling flatus (15%) or faeces (8%)--resolved in all cases. The results of anal dilatation for fissure are generally satisfactory in the longer term, with a trend toward better symptom relief in patients with fissure compared with those with haemorrhoids. We do not recommend anal dilatation as the sole treatment of patients with haemorrhoids, but it may be a useful adjunct to other treatments such as banding or sclerotherapy. Morbidity was generally acceptable and the majority of our patients would be prepared to have this procedure again if their symptoms were to return.

Femorotibial bypass: the learning curve.

Femorotibial bypass is still infrequently performed in many district hospitals, because it is time consuming and the risk of failure is high, especially during the learning curve. This article reviews the results of a single consultant surgeon and his team after starting femorotibial bypass de novo in a district general hospital. During the period 1987 to 1992, 85 femorotibial grafts were performed in 76 patients for ulceration and gangrene (57), rest pain (19) and severe claudication (9). Sixty-six were autogenous vein, 15 were PTFE with distal vein cuff, two were composites and two were umbilical vein. Overall, 22 grafts (26%) failed within the first 30 days (two were salvaged) and 21 amputations were required (five despite patent grafts). There were three early deaths (mortality 3.9%). At the end of 1993, 39 limbs had been amputated and 24 patients had died (eight with amputations). Twenty-three (44% of survivors) were alive with patent grafts. These disappointing early results were due to an initial technical learning curve, after which increased confidence may have led to reconstructing some patients with inadequate distal arteries. A more selective approach is now used. Limb salvage can be achieved in a worthwhile proportion of these patients and 3-year primary patency rates are similar to those of teaching hospitals in this country.

Surgical treatment for venous ulcers: is it worthwhile?

We have reviewed the results of treatment of 159 consecutive limbs presenting with a clinical diagnosis of venous ulcer in 140 patients (70 male, aged 28-90 years, median 66 years). Of the patients, 61% were referred because of severe pain and 53% of the ulcers had been present > 2 years. Patients were evaluated clinically and by Doppler, with selective use of venography, photoplethysmography, arteriography and latterly duplex scanning. Seventy-one limbs had surgery to the superficial veins, 18 limbs had arterial reconstruction, and 10 limbs had skin grafting alone. There was one operative death after arterial reconstruction but none after venous surgery. Patients were followed up for 1-5 years (median 3 years). Of those who had been treated surgically, healing was achieved in 88%, and ulcers healed in 52% of those treated non-operatively. In all, 18% of the ulcers recurred in each group. These results show a favourable association between appropriate venous and arterial surgery and the healing of venous ulcers, with relief of pain. They support a policy of thorough evaluation and appropriate surgical treatment in these patients.

Lower limb amputation: striking the balance.

During a 5-year period, 210 patients (125 male: aged 43-96 years, median 76 years) had 228 primary amputations for peripheral arterial disease. Level selection was by clinical criteria, and there were 148 below-knee (BK, 65%), 72 above-knee (AK, 32%) and eight Gritti-Stokes (GS, 3%). Revision was needed in 43 (19%). The 30-day mortality was 14%. There were 69 patients who had previously undergone bypass grafting (< 30 days in 36; 30 days-1 year 20; > 1 year 13). In these there were 57% BK and 43% AK with a revision rate of 13%--no worse than in patients who had not had attempted limb salvage. Decisions about rehabilitation were made by a team of doctors, nurses and therapists. The 69 patients fitted with prosthetic limbs between 1987 and 1990 were followed up for eventual mobility (minimum 6 months). Of these patients, 81% used their prosthesis at least around the house, but only 16% achieved near normal mobility. This series fails to support the claim that failed arterial bypass surgery prejudices amputation level or healing. Despite attempts to achieve a high rate of below-knee amputation and good rehabilitation, the revision rate remains high and really good prosthesis usage remains low in these elderly patients.

Outpatient clinic review after arterial reconstruction: is it necessary?

After arterial reconstruction, patients have traditionally been followed up in clinic in the long term. We have pursued a policy of limited clinic follow-up, with an 'open access' service for suspected graft failure (and latterly duplex scanning surveillance for vein grafts). This policy was assessed by measurement of the success of self-referral, graft patency and patient satisfaction after operation for lower limb ischaemia in 173 patients. At median follow-up of 50 months, 61 (35%) patients had died and 45 (25%) had required amputation. Of those with salvaged limbs and available for follow-up, 55 (86%) patients reported continuing symptomatic improvement with a graft patency rate of 80%. During the review period, 27 (42%) patients had presented themselves on suspicion of graft occlusion and 14 (52%) of these had required surgical intervention. Of the patients, 45 (70%) found a single postoperative clinic visit helpful, and the majority thought that further visits would not have been helpful to them. Limited clinic appointments seem especially desirable for elderly patients for whom journeys are an imposition, as well as reducing travel costs, and giving surgeons more time to deal with new referrals. These results suggest that properly educated patients present themselves when signs of graft occlusion occur, and there is little to be gained by regular long-term clinic follow-up in vascular surgical practice.
