[Alternatives for closure of the rectal "stump" in Hartmann's operation. A comparative experimental study which includes the resorbable mechanical suture (polysorb)]. / Alternativas de cierre de "muñón" rectal en la operación de Hartmann. Estudio experimental comparativo que incluye sutura mecánica reabsorbible (polisorb).

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.

[Pseudotumoral endometriosis of the colon]. / Endometriosis colónica pseudotumoral.

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.

[Experimental esophageal transsection. Application to the treatment of hemorrhage in portal hypertension]. / La transsection oesophagienne expérimentale. Application au traitement des hémorragies de l'hypertension portale.

Nineteen of twenty dogs undergoing experimental esophageal transection with mechanical suturing were followed up over 1 to 120 days by means of light and electron microscopy examinations to evaluate changes in suture line. Histology showed few reactions to the metallic clips, the absence of new vessel formation with early healing from the 4th day, development of collagen fascicles after 1 week and consolidation after 2 weeks with reparation by the end of 1st month. Stability of healing process was apparent between 3 and 4 months, without evidence of stenosis due to scar tissue.

[Clinical evaluation and pH control in patients with duodenal ulcer treated with ranitidine]. / Evaluación clínica y control pH-métrico de pacientes con úlcera duodenal tratados con ranitidina.

In 31 duodenal ulcer patients treated with ranitidine at regular doses, during four weeks we could prove: a) by endoscopy, the ulcer "epithelization" in 13 patients (41.93%) and a positive response in the other cases; b) a high increase in the intragastric pH after the treatment, with an increase rate of pH 3.288 over the initial medium levels. The clinical-endoscopical response as well as an important increase in the intragastric pH, show the effectiveness of the ranitidine in the treatment of the duodenal ulcer.

[Diagnostic value of esophagoscopy and biopsy in 200 cases of carcinoma of the esophagus]. / Valor diagnóstico de la esofagoscopía y biopsia en 200 casos de carcinoma de esófago.

Two hundred cases of cancer of the esophagus are reviewed. Radiological and endoscopic finding were comparatively evaluated: There were 84% of positive radiological diagnosis, 12,5% highly suspicious and 3,5% negative; the latter were seven cases with the following diagnosis: three megaesophagus, one segmental spasm, esophagitis and hernia, extrinsic compression and normal esophagus, respectively. There were 94,5% of positive; 3,5% doubtful and 2% negative endoscopic diagnosis. There were 94% of positive biopsies and 6% negative. It is emphasized: 1o.) the high percentage of positive histological diagnosis and 2o.) in 3,5% of patients, cancer was found by routine endoscopic examinations.
