Inflammatory fibroid polyp of the gastrointestinal tract.

Details of 13 new cases of inflammatory fibroid polyp of the gastrointestinal tract and of 76 patients recorded in the literature (total 89) are described and analysed. The lesion is always benign, may occur at any age but is commonest in the sixth and seventh decades, and involves the stomach most frequently. Abdominal pain, often related to obstruction, is the principal symptom. Eosinophilia of the peripheral blood does not occur. The lesions are sessile or polypoidal, originate in the gut submucosa, vary greatly in cellularity, and have a wide range of tissue eosinophilia. Some are very vascular, many of the larger vessels having a notably broad zone of connective tissue about them. The aetiology of the condition is discussed and reasons for distinguishing it from eosinophilic gastroenteritis, with which it is frequently confused, are given. The precise nature and aetiology of the inflammatory fibroid polyp remains undetermined.

The role of decubitus films in double-contrast barium enemas.

Five hundred barium enemas were reviewed to find the influence of the decubitus films on the radiologist's report. In two cases they demonstrated abnormalities that had not been seen on any other film. In 21 out of 43 cases they resolved a diagnostic problem that had arisen when viewing the other films. They were of greatest value in differentiating possible polyps from faecal residue in patients with imperfect bowel preparation.

Small-bowel tumors.

BACKGROUND: The rarity, delayed presentation, and diagnostic difficulty of small-bowel tumors prompted this study. STUDY DESIGN: Charts were reviewed retrospectively for 85 patients with 89 small-bowel tumors (22 primary malignant, 23 primary benign, and 44 metastatic) over a 10-year period (1986-1996) at Louisiana State University Medical Center-Shreveport and two affiliated hospitals in Shreveport. RESULTS: Of the primary malignant tumors, 10 carcinoids and 11 duodenal adenocarcinomas were identified. Most primary benign tumors were adenomatous or hyperplastic polyps, diagnosed by esophagogastroduodenoscopy. Metastatic tumors accounted for nearly 50% of all small-bowel tumors. Across all three tumor types, the most common presenting signs and symptoms were abdominal pain and nausea and vomiting. In addition, patients with benign tumors were more commonly presented with gastrointestinal hemorrhage, and those with metastatic tumors were more likely to present with obstruction. The mean interval from the onset of signs and symptoms to operation was 54 days for primary malignant tumors and 330 days for primary benign tumors. Esophagogastroduodenoscopy and computed tomography of the abdomen were occasionally helpful in diagnosis. Among the 22 primary malignant tumors, curative resections were performed in 11 patients (for 9 carcinoids and 2 adenocarcinomas) and palliative resections were performed in 10 patients (for 9 adenocarcinomas and 1 myxoliposarcoma). One patient had carcinomatosis from colon cancer and an incidentally discovered ileal carcinoid; this carcinoid was not included in this group of resections for primary malignant small-bowel tumors. All operations for 39 (of 44) patients with metastatic tumors were palliative. The remaining 5 (of 44) patients had metastatic duodenal cancer (confirmed by esophagogastroduodenoscopy or endoscopic retrograde cholangiopancreatography with biopsy) and did not undergo laparotomy. Surgical complications occurred more commonly with metastatic than with primary malignant tumors. Patients with primary malignant tumors had a 5-year survival rate of 36%. CONCLUSIONS: These findings demonstrate that small-bowel tumors are difficult to diagnose because of delayed presentation, nonspecific signs and symptoms, and lack of accurate diagnostic studies. If the overall survival of patients with small-bowel tumors is to be improved, clinicians must have a high index of suspicion and be willing to perform exploratory celiotomy early.

Clinicopathological study of juvenile polyp.

Thirty-two cases of juvenile polyp were investigated for the clinical and pathological findings. This type polyps occured frequently in the first decade with male predominance. Melena and bloody stool were found in all cases, prolapse of the polyps in 28%, and spontaneous amputation in 9.4%. The duration of symptoms were usually within 6 months. The polyps were found frequently in the rectum and sigmoid colon, about 75%. One case of juvenile polyposis in a 12 years-old male was found. The size of the polyps was usually within 2 cm in diameter and the majority of the polyps were pedunculated. Polypectomy was performed for all cases and additional partial resection for 2 cases with multiple polyps and polyposis. Recurrence and malignant transformation were not found. It should be considered that these are at least two types of histogenesis for the so-called juvenile polyp like as hamartomatous and inflammatory.

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.

Gastric and small bowel polyps in Gardner's syndrome and familial polyposis coli.

The adenomas of Familial Polyposis Coli and of Gardner's syndrome are widely thought to affect the large bowel only. However, this report and a critical review of the literature shows that of the few hundred reported cases of these diseases, at least thirty-six have also shown gastric and/or small bowel polyps. The majority have been concentrated in stomach, duodenum and ampulla of Vater and the latter two areas have shown the highest incidence of carcinoma. It seems that gastric polyps are especially associated with Familial Polyposis Coli, and duodeno-ampullary ones with Gardner's syndrome.

[Removal of polyps from the stomach and large intestine through a fiberscope].

Polypectomy was performed with a special device (a loop and scissors) inserted via the biopsy canal of a fibroscope. During polypectomy diathermic currents from a commerical electric knife are used. An experience with 67 polypectomies has shown that this operation requirs no special pre- and postoperative measures. Failures of polypectomy were as follows: inadequate polypectomy and development of pseudorecurrences, "a loss" of a polyp during its removal, an impossibility ot loop a polyp. Complications that may appear are described.

[Classification of colorectal adenomas based on the histological picture in patients without symptoms].

During screening of colorectal carcinoma by the test of occult haemorrhage in 1985 to 1989 in the Bruntál district during coloscopic examination of positive subjects a total of 277 adenomatous polyps of the large intestine were revealed. Adenomatous polyps were detected in 227 patients where by in 180 solitary polyps were involved and in 47 cases synchronous polyps. 222 adenomatous polyps were in the rectum and left half of the colon (80.1%). Histological examination revealed: tubular adenoma 153 cases (55.23%), tubovillous adenoma 92 cases (33.21%), villous adenoma 13 cases (4.69%), adenoma with intramucous carcinoma 12 cases (4.43%) and adenoma with invasive carcinoma 7 cases (2.53%).

Further studies on lipid-chemical differences between cancerous and adenomatous polypous tissues in the human large intestine.

17 cases of cancer and 18 cases of adenomatous polyp in the large intestine were subjected to lipid-chemical studies of their tissues in order to clarify the biochemical differences between malignant neoplastic growth and benign growth. Cancerous and adenomatous polypous tissues were collected by biopsy or surgical operation together with the respective control tissues. One part of the total lipid extracted from each tissue was separated into triglyceride and phospholipid fraction by a thin-layer chromatography (TLC). The fatty acid composition and content of each lipid fraction were measured by a gas-liquid chromatography (GLC). When the fatty acid composition of a phospholipid was expressed in terms of the deviation rate, that of C14:0 was remarkably increased and that of C20:4 was remarkably decreased in the cancerous cases as compared with the respective values of the cases of adenomatous polyp. More definite differences were recognized between the cancerous cases and the cases of adenomatous polyp, when the ratio of the deviation rate of C14:0 to that of C20:4 was calculated in each case. Namely, the ratios distributed between 2.064 and 4.125 in 10 cancerous cases, and between 0.393 and 1.856 in 16 cases of adenomatous polyp, indicating the biochemical differences between cancerous tissues and adenomatous polypous tissues.

Tumor-associated antigens in polyps and carcinoma of the human large bowel.

The presence of a number of tumor-associated antigens was studied in eight metaplastic polyps, 22 tubulovillous adenomas, and 20 carcinomas. Specific tumor antigens were identified using the immunohistochemical (P.A.P.) technique to detect carcinoembryonic antigen (CEA), human placental lactogen (HPL), alphafetoprotein (AFP), colon-specific antigen (CSA), pregnancy-specific beta lipoprotein 1 (SP1), human beta chorionic gonadotropin (beta hCG), and placental alkaline phosphatase (P Alk P), isoferritins (FE), and transferrin (TF). There is no difference in either the number of antigens present or the number of cases positive for each antigen in cancers and tubulovillous adenomas, but the majority of metaplastic polyps show only CEA and HPL positivity. The two metaplastic polyps showing a full range of positivity were atypical and over 5 mm in diameter. The findings have shown a remarkable similarity between polyps and cancer, which strengthens the concept of the relationship between adenomatous polyps and carcinoma of the colon.

Intraoperative small bowel enteroscopy in familial adenomatous and familial juvenile polyposis.

BACKGROUND: In familial adenomatous polyposis and juvenile polyposis, polyps can occur throughout the gastrointestinal tract. METHODS: We report seven patients with familial adenomatous polyposis and two patients with juvenile polyposis who underwent small bowel enteroscopy at the time of exploratory celiotomy either for colectomy or other pathology. RESULTS: Polyps in the jejunum and/or ileum were noted in five of nine (56%) patients at enteroscopy. In three of nine (33%) patients these polys were adenomatous. Two of these patients had polyps in the jejunum and in the ileum, whereas one patient had jejunal adenomas alone. These polyps were from 3 mm to 30 mm in size. The remaining two patients with polyps had lymphoid hyperplasia in the ileum. All three patients who had adenomas at intraoperative small bowel enteroscopy had duodenal adenomas at esophagogastroduodenoscopy. At the age of 14 years, one patient had an intramucosal carcinoma in a small bowel juvenile polyp. CONCLUSION: Baseline small bowel enteroscopy should be considered at the time of surgical exploration in patients with asymptomatic familial adenomatous polyposis and juvenile polyposis. In patients with duodenal polyps, enteroscopy should be performed at the time of surgery. Biopsy and/or excision of larger polyps should be performed because these polyps may harbor a carcinoma.
