[Lipoma of the colon]. / Les lipomes du côlon.

Two cases of submucosal lipoma of the transverse colon are described with their anatomoclinic characteristics and the different aspects of their treatment. These lesions occur with the maximum frequency in the fifth or sixth decades of life and are mostly found in women. 18 per cent of them are located on the transverse colon. In 10 per cent of the cases, the lipomas are multiple. Their clinical symptoms are directly related to their size. Abdominal pains, rectal bleedings and signs of obstruction are the most common symptoms. Thanks to barium enema and endoscopic examination, they are usually diagnosed preoparatively and may be excised through a colotomy in the majority of cases, or by endoscopic removal.

[Diastatic perforations of the colon of neoplastic origin. Apropos of 15 cases]. / Perforations diastatiques du côlon d'origine néoplasique. A propos de 15 observations.

Typical findings in 15 patients with diastatic perforation of colon due to neoplasm were the preferential site of perforation in cecum and of obstruction in left colon, and the very poor prognosis with postoperative mortality of approximately 50%. The very varied therapeutic attitude is the result of difficulties in deciding which operative procedure is required. When perforation and obstruction are adjacent, a fairly rare observation, radical excision of the segment of intestine involved appears the most suitable operation. When the two lesions are separated then in addition to conservative treatment (suture of perforation and anus bypass or cecostomy alone or combined with colon bypass) an increasing number of authors recommend initial subtotal colectomy.

[Factors in recurrence of perforated duodenal ulcer after simple suture. Therapeutic deductions]. / Les facteurs de récidive des ulcères duodénaux perforés après suture simple. Déductions thérapeutiques.

Objective predisposing factors leading to relapse after simple suture for perforated duodenal ulcer were evaluated by a retrospective study of 80 cases. Statistical analysis showed 3 main factors to be involved: age under 45 years, presence of a previous ulcer ano smoking, and these were attributed a coefficient of severity. A simple method will enable a population at high risk of recurrence to be selected, for which immediate radical treatment can be applied when vital risk factors, also analyzed in this study, are lacking.
