[Malignant colonic polyps: is polypectomy adequate treatment?].

The management of patients with endoscopically removed malignant intestinal polyps is controversial. The risk of residual disease should be assessed against the risk of a surgical operation. The authors report 35 cases of malignant polyps (5.5% of 641 colonoscopically removed adenomas). Sixteen patients had carcinoma in situ and received no further treatment and 19 had invasive carcinoma (sessile in 6, pedunculated in 13). Of these 19, 7 did not undergo surgery--because of old age in 2, minimal invasion in 3, a low rectal location in 1 and refusal in 1. Twelve patients (3 with sessile, 9 with pedunculated polyps) underwent a surgical resection, and residual disease was present in 3 (25%), 1 with positive nodes. Reported criteria of increased risk of residual disease--cancer in lymphatics or veins, incomplete excision, tumour at resection margin, sessile and villous tumours--were present in nine. All three patients with residual disease had microscopically involved margins of resection. The authors believe that the increased risk of recurrence justifies the risk associated with subsequent surgical resection unless the patient is otherwise a poor operative risk.

Inflammatory fibroid polyps of the intestine.

The clinical and pathologic features of 64 inflammatory fibroid polyps of the large and small bowel in 63 patients are reported. Six of the lesions in the small bowel were studied by electron microscopy. Follow-up information was obtained from 39 patients. The lesion was always benign, occurred at all ages, and had a world-wide distribution. The lesions were polypoid, sessile, originated in the submucosa, infiltrated the muscularis propria, and most closely resembled granulation tissue. The principal mesenchymal cell by electron microscopy was the fibroblast. No associated medical conditions were identified and the cause remains unknown.

[Clinical significance of polyps of the large intestine revealed by rectoromanoscopy].

Polyps of distal portions of the large intestine were revealed by rectoromanoscopic examination in 268 patients. In 109 of them solitary and group polyps were found by a colanoscopic examination in proximal portions of ileum, 14 having malignant polyps. In addition, 11 patients had malignant tumors. Polyps in the proximal portions are often found in patients older than 60.

Orbital osteoma in Gardner's syndrome.

A 30-year-old woman developed proptosis secondary to a left ethmoidal compact osteoma. At age 29 years, a mandibular eburnated (ivory) osteoma was excised. At age 25 years, multiple adenomatous polyps of the colon were resected. Her father, age 61 years, had multiple intestinal polyps and bilateral mandibular osteoma. A 24-year-old sister had an osteoma of the forehead. Gardner's syndrome is an autosomal dominantly inherited disorder characterized by intestinal polyposis, various skin and soft tissue tumors, and osteomas of the bony skeleton. Orbital osteomas occur rarely.

Lack of association among typical congenital hypertrophy of the retinal pigment epithelium, adenomatous polyposis, and Gardner syndrome.

BACKGROUND: It has been recently documented that multiple bilateral pigmented lesions at the level of the retinal pigment epithelium may be an indicator of patients with familial adenomatous polyposis who are prone to develop intestinal cancer, particularly if there is a positive family history of these intestinal disorders. Although atypical, such lesions have been called congenital hypertrophy of the retinal pigment epithelium (CHRPE). This study was undertaken to determine whether the typical lesions of CHRPE, seen frequently by ophthalmologists, also were indicators of familial adenomatous polyposis. METHODS: Review of charts and follow-up studies were performed on all patients diagnosed and coded as having solitary CHRPE or its multifocal variant (congenital grouped pigmentation; bear tracks). Patients and their physicians were contacted by telephone to complete a detailed questionnaire designed to detect signs or symptoms of familial adenomatous polyposis or Gardner syndrome among these patients with CHRPE and their relatives. RESULTS: Of the 132 patients with previously diagnosed CHRPE, there were none with familial adenomatous polyposis, Gardner syndrome, or intestinal cancer, and only one patient had a history of intestinal polyps. Among more than 2000 of their blood relatives, only 20 had intestinal polyposis or colonic cancer (1%). This is much lower than would be expected from a survey of patients with the typical fundus lesions seen with familial adenomatous polyposis. CONCLUSIONS: It appears that solitary CHRPE and congenital grouped pigmentation differ clinically from the multiple pigmented lesions seen with familial adenomatous polyposis and that patients with these conditions, as well as their relatives, are not at a greater risk of developing intestinal cancer.

Hamartomatous polyps in the intestine of two dogs.

Partly obstructing, proliferative mucosal masses in the small intestine of two dogs were shown histologically to be hamartomatous polyps. They were characterized by an extension of smooth muscle from the muscularis mucosae into the lamina propria of the lesion. This is the first report of such lesions in domestic animals. In one of the dogs the lesion had become malignant.

Nature of juvenile polyps in the large intestine.

Forty-five juvenile polyps were found among approximately 390 mucosal polyps of the large intestine. Various degrees of epithelial pseudostratification were found among juvenile polyps and the larger-sized polyps of both juvenile type and adult one tended to have a more advanced degree of epithelial pseudostratification. The glands of both juvenile polyps and adult ones revealed a closely resembled or almost identical pattern of size-distribution-pattern of the glandular size in both normal mucosae and hyperplastic mucosae of long-standing ulcerative colitis. Transition of juvenile polyps into adult ones was suggested by the cases with increase in numbers of glands and their orifices to the surface of the polyp and there were some polyps showing an intermediate form between juvenile polyps and adult ones. On the basis of histologic characteristics and age incidence of the patients, it may be said that a juvenile polyp is an immature variant of an adult polyp.

Endorectal pull-through of transplanted colon as part of intestinal transplantation.

BACKGROUND: Two children with life-threatening disorders underwent intestinal transplantation; one multivisceral transplantation excluding the liver, and the second transplantation of the liver, small bowel, and colon. METHODS: Involvement of the native rectum necessitated resection and replacement with the transplanted allograft. To prevent a permanent colostomy, a pull-through of the allograft colon was performed. RESULTS: Both patients had a stormy early postoperative course, mainly because of the complexities of intestinal transplantation, but with eventual recovery, including improvement of rectal function. CONCLUSIONS: These are the first two known cases in which a transplanted large intestine was used for a pull-through procedure.

[Improvement in the resection of intestinal Peutz-Jeghers polyps].

Polyps in patients with Peutz-Jeghers syndrome (PJS) are found in the large and small bowels. In the past, intestinal polyps were treated mainly by multiple abdominal operations. The authors reported resecting 259 polyps in 13 patients with PJS by laparotomy plus colonoscopy via small bowel incision for small intestines, and/or plus colonoscopy via the anus for ileum and large bowel polyps at a time combined with periodic colonoscopy via the anus for colorectal polyps. The largest polyp resected in this way was 10 x 9 x 8 cm. As many as 46 polyps were resected by snare polypectomy at a single colonoscopic attempt. Using the above-mentioned methods, multiple intestinal polyps can be resected more thoroughly, and postoperative recurrence and complication became less frequent.

Mesenteric fibromatosis in Gardner's syndrome.

Gardner's syndrome, first described in the 1950s, is a composite clinical entity characterized by intestinal polyps, osteomas, fibromas, and epidermal cysts. A case of mesenteric fibromatosis in Gardner's syndrome is presented. Whereas most of the literature on this subject stresses the significance of the intestinal polyposis and its premalignant potential, in this paper the serious significance of the intraabdominal fibromas is stressed. This case demonstrates an unusual complication of erosion of this tumor into the small intestine, resulting in multiple intestinal fistulae with abscess formation. Surgical management of this problem necessitated resection of the fibroma and involved small intestine. A review of the literature is presented.
