Peristomal hernia following end-colostomy: a conservative approach.

Available data from follow-up of 183 patients who survived abdominoperineal excision for cancer of the rectum are reviewed. Sixteen patients developed a peristomal hernia, but none required surgical correction for over 20 years of observation. An additional group of 50 long-survivors has been recently examined to verify whether our restrictive surgical indications are adequate. Seven of these patients presented with a hernia, but none suffered obstructive symptoms and surgery was judged unnecessary in every case. Thereby, in our view, the benign evolution of peristomal hernias support a conservative approach based on a confident observation, control of the diseases which increase the abdominal pressure, and hernia compression by a colostomy belt.

Anomalous origin of the right coronary artery from the main pulmonary artery.

A case of anomalous origin of the right coronary artery from the main pulmonary artery, in a previously asymptomatic young woman, is presented. Direct transposition into the aortic root of the anomalous vessel was performed. To our knowledge this is the 4th case of this malformation to be successfully corrected.

Heart valve replacement with the Hancock bioprosthesis. Analysis of long-term results.

Between March 1970 and May 1976, 564 patients have undergone single or multiple heart valve replacement with the Hancock "SGP" bioprosthesis in our institution. Of these patients, 335 had single mitral, 102 aortic, one tricuspid, and 126 double or triple valve replacement, for a total of 629 xenografts. The long-term results, in terms of clinical improvement, survival, and complications, have been analyzed. Significant valve insufficiency secondary to primitive tissue alterations occurred in three patients, while reoperations were required in two for endocarditis and in two others for mitral stenosis caused by tissue ingrowth. We found that thromboembolic episodes occurred mainly in the early postoperative period up to the third month in 10 cases (1.76%). Three patients suffered peripheral embolization during the late follow-up period. Anticoagulants were not administered beyond 3 months postoperatively. Hemodynamic re-evaluation has been performed in 42 patients and the prosthesis has been shown to function properly either in the mitral or the aortic position. The data available to date indicate that the glutaraldehyde-preserved porcine valve is durable and we feel that its use is warranted in any valvular position.

[Rupture of the posterior wall of the left ventricule after replacement of the mitral valve: a description of 8 cases (author's transl)].

Eight cases of left ventricular rupture at the atrio-ventricular groove among 693 mitral valve replacements, isolated or associated with other surgical procedures, are reported. In the authors' opinion, the surgical technique of the mitral valve's removal, especially if calcific or with subvalvular disease, as well as the method and the site of implantation of the prosthesis, are the main factors in determining this severe complication. In order to avoid the rupture of the posterior wall of the left ventricle, a simple modification of the surgical technique which reinforces the valvular annulus is suggested.

Successful treatment of intraoperative rupture of the left ventricle after mitral valve replacement: report of a case and review of the literature.

A case of intraoperative left ventricular rupture following mitral valve replacement, promptly detected and successfully treated, is reported, and the literature concerning 19 other patients successfully treated for this complication is reviewed. Routine inspection of the posterior atrioventricular groove and left ventricular wall is to be recommended after prosthetic mitral valve replacement and before cardiopulmonary bypass is discontinued, to allow recognition of the early signs of ventricular rupture.
