摘要:

&NA;In the past few years, a correlation has been recognized between calcific aortic stenosis and lower gastrointestinal bleeding in elderly patients. It has been suggested by several authors that mucosal arteriovenous malformations, usually in the right colon, are the cause of bleeding in those patients. Although attention is usually focused on doing a partial colectomy (usually right hemicolectomy) for treating colonic arteriovenous malformation bleeding, several patients with calcific aortic stenosis and gastrointestinal bleeding have been reported in whom bleeding stopped after aortic valve replacement alone. The purpose of this paper is to review the possible mechanisms of lower intestinal bleeding in patients with calcific aortic stenosis, delineate the methods of diagnosis, and finally, to outline the appropriate surgical management.

摘要:

&NA;A case of regional metastatic carcinoid of the appendix is presented and the literature reviewed for indications for right colectomy. Five cases of lymph‐node metastasis from primary appendiceal carcinoids less than 2 cm in diameter have been reported. There is no reported case of systemic metastasis occurring after appendectomy for a carcinoid with a diameter of less than 2 cm. Perineural involvement, lymphatic invasion, mesoappendiceal invasion, histologic appearance, and location of the tumor in the appendix seem to be unreliable predictors of clinically significant regional node involvement. It is concluded that a right colectomy is indicated only in patients with carcinoid tumors of the appendix 2 cm or more in diameter, or with residual tumor at the margin of resection.

摘要:

&NA;The experience with 6299mTc‐labeledin vivoscans performed for lower gastrointestinal bleeding is discussed. Thirty‐seven scans were deemed positive. The tendency of scans to become positive correlated with observations of active bleeding. Five patients had fulminant hemorrhage, necessitating emergency operation. In this group, scanning accurately located the bleeding sources prior to intervention. Seven other patients having later operations bled less rapidly. The bleeding site was localized accurately by scanning in three of these patients. Two studies were falsely positive and two were negative, whereas angiography was positive in two patients studied.Labeled RBC scanning is a useful technique in the early evaluation of patients with lower gastrointestinal bleeding, obviating the need of arteriography in some cases.

摘要:

&NA;Mesenteric desmoid tumors are a recognized sequela of colectomy for polyposis coli of Gardner's type. Relentless growth and recurrence carry a poor prognosis. Recently, nonsteroidal anti‐inflammatory drugs have been used to halt the growth of these tumors, presumably by interfering with prostaglandin metabolism. A 36‐year‐old man presented with small‐bowel obstruction secondary to a large, diffuse mesenteric desmoid six years following colectomy and ileoproctostomy. Laparotomy revealed it to be unresectable. Postoperatively, he was started on sulindac (Clinoril®) 100 mg twice a day. His obstruction resolved, and he remains well at 11 months. A CT scan shows diminution in the size of the tumor. Nonsteroidal anti‐inflammatory agents may be an alternative to chemotherapy and radiotherapy in treating mesenteric desmoids.
