Epithelial polyps of the large bowel: a pathological and colonoscopic study.

Ninety patients who had epithelial polyps or carcinoma of the large bowel and underwent at least 2 colonscopic examinations were studied. The cases were divided into three groups: patients who ;ad only one polyp; those in whom more than one epithelial polyp were found and those who had adenocarcinoma of the large bowel and underwent follow-up colonoscopic examinations. The distribution of the polpys was plotted as to type and distribution in the colon. There seemed to be a trend for the polyp found in follow-up examinations to be located proximal to the splenic flexure. In this regard it was noted that the subsequently found polyps in group II were smaller than those removed on the initial colonoscopic examination. No relationship could be found between any histologic type of epithelial polyp and the presence of carcinoma.

Adenocarcinoma

The small carcinoma of the large bowel.

Four small carcinomas (3, 6, 10, and 15 mm) of the large intestine have been examined for residual epithelial polyp; none was found. It is felt that these carcinomas arose from colonic mucosa without a preexisting visible epithelial precursor lesion; however, occasional glands having adenomatous change were seen near the edges of the carcinomas.

Adenocarcinoma

Recurrent hemolytic anemia secondary to acessory spleens.

A patient with recurrent hereditary spherocytosis due to a hypertrophied accessory spleen is presented. In patients in whom splenectomy is performed for hematologic disease, accessory spleens must be sought and removed. Recurrence of the inital disease should prompt a search for accessory spleens.

Nature and significance of colonic polyps.

The concept of inevitable premalignancy in all adenomatous polyps of the colon was challenged as early as 1958, and since that time much debate has centered about the malignant potential of adenomatous polyps of the colon. Current thinking indicates that the majority of colonic polyps fall into one of four categories: hyperplastic, villous adenoma, adenomatous, and villoglandular. Analysis of the present series of 387 colonic polyps removed endoscopically indicates that the villoglandular group has a notable malignant potential, and that the pure adenomatous polyp probably carries a minimal malignant threat. The present series does not challenge the accepted concept that hyperplastic polyps are of no malignant potential, and that villous adenomas are quite frequently malignant at the time of diagnosis.

Colonic Neoplasms

Endoscopic removal of bleeding brunner gland adenoma.

A 36-year-old man had a major hematemesis because of a Brunner gland adenoma in the postbulbar portion of the duodenum. Three months later, the adenoma was successfully removed electively via endoscopic polypectomy. This is the first patient reported, to our knowledge, to have this technique for a bleeding Brunner gland adenoma. Endoscopic surgery is a relatively new development, and the technique of polypectomy has been used primarily in the colon. Surgery via upper gastrointestinal endoscopy promises to be as useful, although a somewhat different set of precautions applies.

Adenoma

Arteriomesenteric duodenal compression syndrome: comparison of methods of treatment.

A group of 80 patients with arteriomesenteric duodenal compression syndrome was reviewed, 48 from the general population and 32 from the Hines, Illinois, VA Hospital. Differences in the patient populations are pointed out, as are differences in the therapeutic results. An additional series is reported. Duodenojejunostomy is a safe and effective operation for the majority of patients who require surgery for this condition, and patients are less likely to require further medical or surgical care than those who have section of the ligament of Treitz.

Adolescent

Endoscopic removal of gastric and duodenal polyps.

As endoscopic surgery comes into its own, the applications of this modality are increasing. This is well illustrated by the use of endoscopic polypectomy in the colon, and more recently by endoscopic polypectomy in the stomach and duodenum. We can anticipate increased applicability of these technics as the experience widens and the margins of safety increase. The present series of six polypectomies from the stomach and duodenum confirms the applicability of endoscopic polypectomy for this portion of the gastrointestinal tract, attests to its safety, and indicates that these procedures can contribute materially to the care of patients with gastric or duodenal polyps. The real and potential problems are discussed.

Adenoma

Pelvic lipomatosis.

A case report of pelvic lipomatosis in a woman is presented. This condition is a benign, apparently self-limited disease in which mature adipose tissue is deposited in the pelvis. The clinical presentation is discussed.

Adult

The surgical and hematologic significance of accessory spleens.

The approximately 10 per cent incidence of accessory spleens in the general population is well documented, and accessory spleens often are not clinically significant. Trauma, torsion and, especially, hematologic diseases can affect an accessory spleen. A careful search should be made for accessory spleens, and they should be removed at the time of primary splenectomy so as to avoid a second operation later in life.

Adult

Prosthetic fitting immediately after below-knee amputation.

Frequently surgical amputation of a lower extremity is required when gangrene develops as a result of peripheral vascular disease. This is particularly true in geriatric patients. A below-knee amputation, with refinements in the surgical procedure, and immediate rigid-cast prosthetic fitting are strongly advocated by our group. The progress of two patients treated in this manner is described. Preservation of the knee joint improves the amputee's prognosis for ambulation with a below-knee prosthesis. The rigid-cast dressing on the below-knee amputation reduces edema and postoperative pain, is of psychologic value to the patient, and permits him to stand at from one to two days postoperatively.

Colonoscopy: Its principles and applications.

Fiberoptic colonoscopy has seen its early development in the past five years and in the last two to three years a rapidly expanding experience has developed. The use of this instrument has been documented abundantly both as a diagnostic tool and as a therapeutic tool, and its effectiveness in both areas is well established. The chief therapeutic use of the colonoscope is in the removal of polyps, and in this area the experience has been most gratifying in regard to the ability to remove most polyps and the low incidencs of complications.
