RESUMO
Five different kinds of sutures which can be used for closure of the rectal stump in Hartmann's operation are evaluated in the same animal. They are compared at six different phases of the cicatrization process: 7-30-45-60-90 and 150 days. In the analysis, the degree of complete cicatrization is considered as well as the thickness of the cicatriced tissue, and other factors such as persistence of suture material and the result of it. All of the sutures involved accomplished the goal of a good joint of the planes of intestinal suture. Although, two of them, the metal stapler and Polyglactin (Vicryl) in extramucosal surgery fulfill almost in an ideal way the goals concerning security, rare reaction to suture material, and consequently less thickness in the cicatriced tissue (2 x 2 and 1 x 1 mm respectively) as well as complete cicatrization in ninety days. Stapler is performed quicker and in a more aseptic way, but the scar resulting from Polyglactin is smaller. In separate extramucosal points, silk produces a more important tissue reaction with a thicker scar (3 x 3 mm) coming to an end in 150 days. "Albert Lembert" type suture is really far away from being a good mean because it creates an important tissue reaction with a thick scar (3 x 3 mm), with late consolidation (150 days) and granulomatous reaction. Resorbable stapler--Polisorb--has a considerable volume and it causes an important tissue reaction which determines a very thick (4.5 x 4.5 mm) and "unfinished" scar within 150 days; really far away for practical use.

RESUMO
Four cases of colonic endometriosis are reported. Three of them had combined treatment: surgical resection followed by hormonal therapy. The remaining one, just pharmacological treatment. The results were considered satisfactory. The authors had reviewed the disease, the diagnostic procedures, advising for the colonic involvement surgical resection plus hormonal therapy. Danazol is considered the pharmacological agent of choice. They concluded that endometriosis involves the digestive system in 12% of the patients, with good prognosis if properly treated.

De acuerdo con lo que acabamos de informar, pensamos que podemos enunciar lo siguiente: 1) Que los datos observados nos permiten decir que existe coincidencia con los obtenidos por otros dermato-leprologos, pero actualizados con la terapeutica que poseemos. 2) Que es necesario intensificar los estudios sobre lepra infantil porque consideramos que nos permitiran aclarar incognitas pendientes de solucion, con especial referencia a la epidemiologia y patogenia de la enfermedad
