BACKGROUND Bowel reconstruction after subtotal esophagectomy represents a problem when a previous distal gastrectomy was performed: usually the colon or jejunum is used. METHODS In a 10 year period 126 patients with primary esophageal cancer underwent esophageal resection in our Department. Surgical procedures were 57% two-phase subtotal oesophagectomy, 23% transhiatal, 9% stripping, 10 three...

Seven patients are presented each with symptomatic malignant melanoma metastases to the alimentary tract. Where practicable, surgical excision of the metastases is justified because two patients have had worthwhile periods of survival.

Smooth muscle tumors (SMT) of the alimentary tract are uncommon. A series of 32 cases (16 leiomyomas and 16 leiomyosarcomas) are presented. The most common presenting clinical signs are bleeding or obstruction. These are caused mainly by degenerative changes within the lesion or its enlargement. The endoluminal SMT cause symptoms early and are more easily detectable. However, the extraluminal S...

Isolated duplications of the alimentary tract are rare congenital malformations with a reported incidence of 1:5000.1,2 Duplication anomalies of the pyloroduodenal region are not common as well. Intestinal duplications should be considered if additional specific development malformations are present. The aetiology of duplication cysts may be multifactorial.3 The usual symptoms in patients with ...

Histological development of digestive tract of the Caspian salmon, Salmo trutta caspius, from hatching to 6 month post-hatching was studied using light microscope. The digestive tract of newly hatched larvae was a simple, undifferentiated tube which continued from mouth to anus. In 10 days post hatching larvae, the alimentary canal became more differentiated and secretion was started activity, ...
