The study aim was to report an adenocarcinoma of the anal glands revealed by an anal abscess in a 64-year-old man. Malignant transformation of an anal fistula is discussed in the genesis of this disease. Clinical symptoms are not specific. Abdomino-perineal resection of the rectum is the usual surgical treatment and adjuvant radiation therapy didn't prove its efficiency.
Inflammatory pseudotumor of the spleen is a very rare benign lesion of unknown etiology. Splenectomy is recommended to obtain histological diagnosis and to eliminate a malignant tumor.

Authors report 121 cases of post bulbary ulcers between 1969 and 1987. They precise the frequency of complications in this localisations of the ulcerous disease: Hemorrhage: 38% Stenosis: 39.6% Peritonitis through perforation: 9.09% Anatomical reports of the post bulbary area explain the anatomo-pathological aspects made by the above mentioned complications added the biliodigestive fistula and perforations blocked of a surgical treatment. Considering these elements, the authors show the difficulty of a surgical treatment. They suggest choosing the most simple intervention: Treating the ulcer without approaching the ulceron area; namely; making truncal vagotomy and duodenoplasty, that of Finney being the most adapted in case of haemorrhage. On case of a stenosis, with gastric ditension, exclusion gastrectomy is the adequate intervention. The results are good, except two deaths that occurred by cataclysmic ulcerous haemorrhage.
This work is based on 140 cases of esophageal reconstructions collected during 17 years from 1970 to 1987. Those interventions were performed for 62 cancerous esophageal lesions, 8 peptic stenosis and 70 caustic stenosis. The immediate and long-term results will be presented. Important points of the reconstructions will be stressed.

To look for the explanation about the post-cholecystectomy syndrome, the authors study 637 liver's biopsies during cholecystectomy for cholelithiasis. 373 liver's biopsies showed hepatic lesions (58.5 per cent). The post-cholecystectomy syndrome is observed in 36 per cent of patients who had hepatic lesions, and only 13 per cent of patients with normal liver biopsies.
Three types of porto-systemic shunt were performed in the dog following 65% hepatectomy with the aim of determining the best porto-systemic shunt for the maintenance of hepatic function during regeneration of the liver: terminolateral portocaval shunt, mesenterico-caval shunt and spleno-pancreatico-caval shunt. The hepatic functions studied were the hydroxylation of vitamin D and proaccelerin synthesis. These functions were unaffected by the mesenterico-caval shunt whilst they were depressed to the same extent by both other types of shunt.
