The aim of this article is above all to describe a new experimental protocol of caustic stenosis of the oesophagus in the rat, a protocol leading to regular stanoic scarring and offering and experimental model for the trial of anti-collagen substances. Initial research with d-penicillamine appears to offer encouraging results which justify its continuation.
The authors report 3 cases of intestinal bleeding either micro- or macroscopic induced by ulcers in blind loops. The blind loops developed in all 3 cases on side-to-side ileocolic anastomoses. In one of the patients, the ulcers were demonstrated by colonoscopy. The 3 cases reported are quite comparable to the 18 cases found in the world literature. These hemorrhages may become severe by their abundance or repetition, but a cure is easily obtained by resection of the intestinal blind loops and restoration of the continuity by end-to-end anastomosis.

In a patient with an adenocarcinoma of the ascending colon, the jejunal central villous lymphatics were dilated and contained tumour cells. This case, apparently the only one of its type, demonstrates the proof of a phenomenon sometimes described in connection with malignant diseases, but rarely proven; that of the dissemination of tumour cells by reversal of lymphatic flow.
