Traumatic perforation of the oesophagus is potentially life-threatening. Primary closure may compromise luminal diameter if the defect is large. This report describes the use of a primary sternocleidomastoid flap in the repair of a gunshot injury to the cervical oesophagus.

The use of artificial grafts was proposed to facilitate the construction of palliative bilio-enteric bypass in proximal malignant biliary obstruction. Previous reported clinical experience is favorable. We present herein our preliminary clinical and experimental experience with Dacron and PTFE (Goretex) vascular grafts for the construction of bilio-duodenal bypass. Although our clinical results appear encouraging, the use of these prosthetic conduits is not supported by experimental data obtained in dogs.
Nonmedullary thyroid carcinoma is known to occur in association with primary hyperparathyroidism. A combination of secondary, uremic, hyperparathyroidism and non-medullary thyroid carcinoma is rare and was hitherto reported in only 12 cases. We report another three patients with this parathyroid/thyroid disease combination, suggesting that it may represent not merely a coincidence. A number of factors active in secondary hyperparathyroidism may play a role in the induction and/or promotion of the thyroid cancer. These include parathyroid endocrinopathy, goiterogenic effect of prolonged hypercalcemia, and uremia. During surgery on the parathyroid glands, associated thyroid lesions demand special considerations.
