Intussusception in adults is rare. Symptoms are often uncharacteristic. Therefore diagnosis is difficult. Diagnosis can be confirmed by radiologic and endoscopic measures. Surgical treatment consists in the resection of the struck part of the intestine according to the principles of tumor surgery. The danger of perforation rises if desinvagination is tried. It is reported about 11 own cases in which 7 neoplasms were the cause of intussusception. Two patients died of aspiration pneumonia and intracerebral hemorrhage caused by rupture of an aneurysm of the cerebri media artery.

We describe a technique for nephroureterectomy that includes ureteral intussusception and transurethral ureteral resection and our method for transurethral ureteral pull-through. These adjuncts permit total nephroureterectomy through a single skin incision and are appropriate in all cases except in patients with known high-grade transitional cell carcinoma of the renal pelvis or ureter. In 18 cases, these techniques have been shown to be reliable, safe, and rapid; in the 14 patients under observation for five years or longer, there have been no local recurrences of tumor.

A patient with a hemangiopericytoma of the colon is discussed. This is the second such case reported in the English medical literature. Soon after discovery of the tumor, the patient presented with a colonic intussusception with the tumor serving as the lead point. This was reduced by a hypaque enema, but the intussusception recurred twice more, being reduced again by hypaque enema and finally having to be reduced by colonoscopy. At surgery a left hemicolectomy with primary anastomosis was performed. The microscopic, ultrastructural, and pathologic aspects of hemangiopericytoma are discussed with special attention to lesions of the gastrointestinal tract.

Report on a case of intestinal obstruction due to a sigmoido-rectal and afterwards anal intussusception of a malignant tumor : review of the literature. Colo-anal intussusception remain very rare as, since Lataste in 1975 related six cases, this one is unique. On the contrary seven new cases of colo-rectal intussusception have been reported. Diagnosis can be difficult. The variability of the mass revealed by successive examination and the intussusception pictures sometime provided by the barium enema may give the correct direction. In this case, treatment consists in the perineal resection of the sigmoid intussusception and its causal tumor followed by an end to end primary anastomosis with an iliac colostomy. This treatment seems to be more suitable for old and deficient people where carcinologic problem is not of first importance.

A mass associated with the gastrointestinal tract was detected by sonography in 33 patients. Etiologies included primary or metastatic tumor; intussusception; inflammation secondary to bowel infarction, pancreatitis, or irradiation; and a dilated, fluid-filled gut related to retained gastric contents, obstruction, ileus, or an ileal bypass. Mesenteric or omental changes were identified with inflammation and frequently with metastatic disease. The diagnosis was confirmed by repeat sonography, abdominal radiography, barium examination of the small bowel, computed tomography, surgery, or autopsy. Ultrasound patterns are characteristic in tumor, intussusception, and inflammation; specific features allowing differentiation between tumor and inflammation are described. Colonic haustra, valvulae conniventes, or bowel contours and peristalsis on real-time sonography are helpful in identifying fluid-filled bowel loops.

Albino noninbred weanling male and female rats were fed a basic grain diet (Group 1) or a basic diet supplemented with 33% bracken fern [BF (Group 2)] or 0.1% quercetin [purity, > 99% (Group 3)] for 58 weeks. The quantities of quercetin and kaempferol (a close structural analog) in BF as glycosides were determined to be 0.57 and 1.1 g, respectively, per kg of dried BF. Estimated mean total cumulative doses (mmol) per rat were: Group 1, quercetin, males and females < 0.03; kaempferol, males and females < 0.03; Group 2, quercetin, males 5.8, females 5.2; kaempferol, males 11.9, females 10.8; and Group 3, quercetin, males 27.8, females 25.3; kaempferol, males and females < 0.03. Growth of rats fed BF or quercetin was comparable but significantly (p < 0.01) slower after 24 weeks than that of Group 1. Mean survivals (weeks) of rats of all groups were: Group 1, 58 +/- 7 (S.D.); Group 2, 51 +/- 13; and Group 3, 56 +/- 8. They were not significantly different, although rats fed BF tended to die earlier secondary to intestinal tumor-induced intussusception and obstruction. The following incidences of intestinal or bladder neoplasms in male or female rats, respectively, were observed: Group 1, intestinal and bladder, males, 0 of 9, females, 0 of 10; Group 2, intestinal, males, 7 of 8, females, 10 of 11; bladder, males, 6 of 8, females 8 of 11; Group 3, intestinal, males, 6 of 7, females, 14 of 18; bladder, males, 2 of 7, females, 3 of 18. The histopathology of neoplasms of the 2 target organs was identical for rats of Groups 2 and 3. Multiple ileal intestinal neoplasms of rats fed quercetin included: adenoma, 4; fibroadenoma, 7; and adenocarcinoma, 9 (with mesenteric metastases, 3). The 5 bladder tumors were papillary or sessile transitional cell carcinomas.

It is now apparent that distinction between the so-called malignant histiocytosis and lymphoma can be made using panels of established immunohistochemical markers and/or genotypic analysis. Many, if not all, of the previously diagnosed cases of malignant histiocytosis have been shown to be of lymphoid, rather than histiocytic, lineage. We report a rare case of colonic histiocytic neoplasm accompanied by a lymphoreticular dissemination that mimicked that of malignant histiocytosis. In addition, barium studies and computed axial tomography confirmed an intussusception that subsequently developed. The histiocytic nature of the neoplastic cells was supported by immunohistochemical, ultrastructural, and cytochemical studies. To our knowledge our case may represent the fifth documented case of a histiocytic malignancy reported in the literature. The relationship among the various cases will be discussed as well as the significance of the focal S-100 immunoreactivity observed in the present case.

The literature concerning gastric tumors in children is mainly limited to case studies. The authors reviewed 1,403 histological reports of pediatric gastric pathology (covering 10 years) at their institution. There were three gastric tumors of benign histology and no malignant tumors. The first patient was a 9 1/2-year-old boy who presented with several months of symptomatic, pH-probe-confirmed gastroesophageal reflux. He underwent placement of a Toupet antireflux valve. During laparotomy, a submucosal mass was discovered incidentally, on the greater curvature of the stomach. The mass was excised. Pathological examination showed heterotopic pancreas. The second patient, a 15-month-old girl, presented with a short period of vomiting. Results of an upper gastrointestinal series showed gastric outlet obstruction. She underwent laparotomy and was found to have an intussusception of a gastric polyp into the proximal jejunum, and an associated malrotation. Ladd's procedure, gastroduoduodenostomy with reduction of the intussuscepted polyp, and excision of the polyp were performed. Histological examination of the tumor showed hamartoma with hyperplastic elements. The tumor was benign but was regarded as difficult to classify. The third patient, a 6-year-old boy, presented with microcytic anemia. Endoscopy showed multiple friable bleeding gastric masses. He underwent laparotomy, with partial gastrectomy and pyloroplasty. Histological examination showed the tumor to be plasma cell granuloma. The tumor recurred, and the patient required subsequent operative procedures. The authors confirm that gastric tumors in children are rare. Although the tumor histology may be benign, excision of the tumor may require major operative resection.

We treated a patient with a complete invagination of the cecum that contained two large laminated calcified fecaliths. Colonofiberscopy showed a dimpling submucosal tumor that was palpated as a bony hard tumor at laparotomy. This finding suggested that the fecaliths caused intussusception of the cecum and that such an intussusception should be suspected when a bony hard, dimpling submucosal tumor is found in the cecum. To our knowledge, this is the first reported case of a cecal invagination accompanied by calcified fecaliths without an appendical intussusception.

Gastroduodenal intussusception is a rarely documented condition. A distinction has to be made between complete gastroduodenal intussusception (CGDI) and either prolapse of a pedunculated tumor through the pylorus or mucosal prolapse through the pylorus. CGDI usually occurs secondary to a pedunculated benign gastric tumor. More rarely the tumor is malignant. We report a case of CGDI associated with gastric adenocarcinoma. We emphasize diagnostic difficulties that can be generated by CGDI.
