Differential patterns of vasculature to liver tumours.

An angiographic study of the vasculature of Vx2 tumour deposits in the rabbit's liver is described.Tumours transplanted from donor rabbits within less than 2 weeks incubation, developed into an amorphic infiltrating tumour, characterized by a rich arterial network. Tumours harvested after 3 weeks growth in donors, became cystic and had a scanty arterial supply.In both groups there was no portal circulation to the tumours' deposits.It is suggested that prior to intra-arterial treatment of cancer in the liver, the morphology of the tumour should be assessed.

Perforation of the sigmoid colon simulating acute appendicitis.

Diverticulitis and carcinoma with abscess formation following perforation of the redundant sigmoid colon was erroneously diagnosed as acute appendicitis in nine patients over a period of five years. As te inflammatory process develops in the right lower quadrant of the abdomen, lack of previous colonic pathology may lead to a misdiagnosis, usually of acute appendicitis. It should be borne in mind, however, that acute appendicitis decreases with age, whereas diverticula and carcinomas increase, and that the sigmoid colon is often a redundant organ with a tendency to migrate to the right side of the abdomen. In elderly patients with acute right abdominal pathology, it is important to operate through a transrectal or paramedian incision. A two-stage operation is preferable to a three-stage one.
