Excision biopsy of malignant melanoma by general practitioners in south east Scotland 1982-91.

OBJECTIVE: To examine the management of patients who had a malignant melanoma excised initially by general practitioners in south east Scotland over the past 10 years and to assess the impact of the April 1990 contract on this. DESIGN: A retrospective case-control study. SETTING: South east Scotland. SUBJECTS: All patients in south east Scotland who had malignant melanomas excised by general practitioners in 1982-91. OUTCOME MEASURES: Demographic details of patients; Breslow thickness, clearance of excision. RESULTS: 42 patients had malignant melanomas excised by general practitioners in 1982-91: 15 in 1982-9 and 27 in 1990-1. These patients were significantly younger than those who had their tumours excised initially in hospital. Although the longest diameter of melanomas excised by general practitioners was significantly less than of those excised in hospital, the Breslow thicknesses were similar. Completeness of initial excision was doubtful or incomplete in nine (23%) general practitioner excisions compared with 4% of hospital excisions, but the time interval between excision biopsy and wide excision was similar. Pathology requests accompanying excision biopsies mentioned melanoma as a possible diagnosis in 15% (6/40) of general practitioner cases compared with 79% of hospital cases. Thirty nine general practitioners responded to a questionnaire and only 12 had considered melanoma in the differential diagnosis. CONCLUSIONS: General practitioners need to think more often of malignant melanoma when they excise pigmented lesions and when they consider this tumour a possibility should perform an excision biopsy with a lateral clearance of at least 2 mm.

Obstructing carcinoma of the left colon managed by subtotal colectomy.

Obstructing carcinomas of the left colon are traditionally managed with a staged resection, as immediate colonic anastomosis is associated with a high risk of anastomotic dehiscence. We have prospectively performed total or subtotal colectomy in 18 consecutive patients presenting with obstruction at or distal to the splenic flexure. The operative mortality was 11%, which compared favourably with the results of other methods of surgical management. The procedure is safe and no cases of anastomotic dehiscence occurred. Subtotal colectomy achieves in a single procedure relief of the obstruction, tumour resection and restoration of gut continuity whilst allowing resection of synchronous lesions and eliminating the risk of metachronous tumour. Frequent liquid stool was not a significant sequel of a subtotal colectomy in this series.

Prophylactic subcutaneous heparin does not increase operative blood loss in transurethral resection of the prostate.

A prospective randomised study of subcutaneous heparin compared with no heparin was performed in 60 patients undergoing transurethral resection of the prostate. Operative blood loss in the irrigation fluid was measured using a haemoglobinometer. Blood loss correlated with the amount of prostate resected and the duration of the procedure. Subcutaneous heparin had no significant effect on the measured blood loss in transurethral resection of the prostate and can be used as a safe means of prophylaxis against thrombo-embolic complications.

An alternative method of draining the pelvis after excision of the rectum and anterior resections.

An alternative method of draining the extraperitoneal pelvis using a constant suction and irrigation drain in the retrorectal space was used in 16 patients undergoing excisional or restorative rectal operation for either inflammatory intestine disease or carcinoma. A transient fecal fluid leak from the drain site developed in one patient. The other patients showed no clinical evidence of anastomotic leakage or infective operative complication. We believe that continuous low pressure suction drainage and irrigation of the retrorectal space is important in the healing of excision and restorative operations of the rectum.

Ischaemic colitis associated with psychotropic drugs.

Two cases of patients with ischaemic colitis requiring operative treatment are presented. Both had received a commonly used psychotropic drug in large dosage before the acute episode. Evidence is produced which may link the drugs used with the condition of ischaemic colitis.

The single cannula method.

The single cannula method adds a useful technique to methods of performing preoperative cholangiography. Its main advantages are evident in the more difficult tasks of obtaining satisfactory postexploration (completion) roentgenograms where it adds an alternative technique to the two methods available.

Scissor excision of anogenital warts.

Anogenital warts were treated by scissor excision in 34 patients while under general anaesthesia; most patients were referred by the department of genitourinary medicine. In 28 patients who were adequately followed up the primary success rate was 71.4% and the rate of recurrence of warts was 9.3%. The technique gave good cosmetic results with few complications.
