Acute diverticulitis of the caecum.

Two cases of inflammation of a solitary diverticulum of the caecum are reported. These probably represent the first cases to be reported in Chinese. The pathogenesis of solitary diverticulum of the caecum is different from that of multiple diverticulosis of the colon. A study of these cases was made to understand better this uncommon entity. Before operation, the symptoms, signs and physical findings of caecal diverticulitis are those found in appendicitis. The diagnosis at operation in some cases is difficult because the inflammatory reaction may simulate a malignant process. Local excision is the operation of choice. Our two patients were treated by right hemicolectomy. Discussion is presented of the clinical presentation, pathology and treatment of this condition, so that its prompt recognition may avoid the incorrect diagnosis of caecal malignancy, which in turn would lead to unnecessary radical surgery resulting in a high mortality rate.

Significance of early and late positive responses to insulin hypoglycaemia in patients with intact vagi.

Insulin tests were performed on 100 subjects with duodenal ulcer who had not undergone surgery. Thirty-seven per cent had ;late' positive responses to insulin. It was suggested that a late response to insulin after surgery was not necessarily an indication of ;adequate' vagotomy. The secretory responses to insulin before operation revealed no difference in peak acid concentrations or outputs between those with early and late responses. Basal acid concentrations were higher in those with late responses, though the difference was only significant when the division between early and late responses was made at 60 minutes. The distribution of the timing of the peak responses suggested that the division into ;early' and ;late' responders was artificial.
