Management of an unexpected appendiceal neoplasm.

BACKGROUND: Appendiceal neoplasms are rare and most present unexpectedly as acute appendicitis. The classification and management are confusing, and there are few substantial reports in the literature. METHODS: A systematic literature review was performed to access relevant publications on the presentation, pathology and management of appendiceal tumours. RESULTS: Appendiceal tumours account for 0.4 to 1 per cent of all gastrointestinal tract malignancies and are found in 0.7 to 1.7 per cent of appendicectomy specimens. Carcinoid tumours are most common. Most are cured by simple appendicectomy if the tumour is less than 2 cm in size and does not involve the resection margin or mesoappendix. Epithelial tumours may present with, or in time develop, pseudomyxoma peritonei, the optimal management of which involves complete tumour resection and intraperitoneal chemotherapy, usually available only in specialized centres. CONCLUSION: Suggested algorithms for the management of unexpected appendiceal tumours are provided. Recommendations are made for follow-up of patients with a perforated appendiceal epithelial tumour.

Surgical decisions in the elderly: the importance of biological age.

Surgeons will sometimes advise against an operation because the patient is 'old and frail'. A simple starring system (one to five), based on performance and lifestyle, has been devised to assess the biological age of elderly patients. 10 consultant surgeons and 10 trainees answered questions about their treatment recommendations for hypothetical patients of standard age and medical history but with various star ratings and surgical conditions. 1000 decisions were available for analysis. The four and five star patients (those leading an independent existence) were recommended 266 interventions, the one and two star patients 55. Trainees were more inclined to intervene than consultants, recommending operations in half the patients rather than one-third. These results indicate that decisions on surgical management are strongly influenced by the patient's star rating or biological age. If the starring method proves reproducible in other patient groups and settings, it could allow better communication on an important factor in clinical decisions.

Wound infection following high saphenous ligation. A trial comparing two skin closure techniques: subcuticular polyglycolic acid and interrupted monofilament nylon mattress sutures.

A prospective, randomized trial was performed to compare the incidence of wound infection following skin closure with subcuticular polyglycolic acid and interrupted monofilament nylon mattress sutures in patients undergoing high saphenous ligation (126 patients; 75 polyglycolic acid wounds, 86 interrupted monofilament nylon mattress wounds). By 6 weeks after operation, pus had discharged from 15 (20%) polyglycolic acid wounds compared with seven (8%) interrupted monofilament nylon mattress wounds (P = 0.05), giving an overall infection rate of 13.7%. Infection occurred in 23% of the 56 procedures performed by the two surgeons with the highest infection rates compared with 8% of the 105 procedures performed by the remaining nine surgeons (P = 0.02). The excess of infections in wounds closed with subcuticular polyglycolic acid was caused by an excess of infections in operations performed by the two surgeons with the highest infection rates. The higher infection rate found with subcuticular polyglycolic acid appeared to be operator dependent.

Growth patterns and nutrition in Nepali children.

A growth survey of four groups of Nepali children from birth to 12 years was undertaken and the growth patterns related to diet. The patterns are those of children suffering from malnutrition in the second and third year and not those of a genetically small race. Diet histories showed inadequacies of diet, mostly preventable, occurring during the same period. Privileged children within the groups showed a different pattern and a significantly better growth.
