The hemolytic-uremic syndrome consists of microangiopathic hemolytic anemia, acute renal failure, and thrombocytopenia following a prodromal illness of gastroenteritis or upper respiratory infection. The syndrome can present in dramatic fashion with severe abdominal pain and signs of peritonitis suggesting an acute surgical crisis. In a series of 25 patients, 40% had abdominal pain, 25% had abdominal tenderness, and 20% had peritoneal signs. Clues to diagnosis in the early stages of the acute illness were mild to moderate hypertension, abnormal peripheral blood smear, anemia despite dehydration, and proteinuria. Significant abdominal pain and x-ray evidence of colitis may occur before development of typical laboratory findings, and these were evident in at least one case. Three patients underwent laparotomy for suspected bowel perforation. Colitis without perforation was found in all cases. In the absence of documented perforation, toxic megacolon, or intussusception, the decision to perform laparotomy in patients with hemolytic-uremic syndrome who have signs of peritonitis must be individualized. Failure to recognize the underlying renal problem can lead to serious errors in fluid and electrolyte management and delay of appropriate therapy.

Small focal areas of intestinal infarction were produced experimentally in mice by two techniques: (1) intussusception and (2) suture strangulation of a loop of jejunum. The radionuclide technetium 99m diphosphonate (99mTc-diphosphonate) was subsequently administered intravenously, and abdominal scans were obtained. The scans demonstrated focal infarcted lesions accurately, and every positive scan was associated with an area of infarction, as demonstrated by pathologic examination. However, negative scans did not definitely exclude an area of infarction: in the intussusception study there were five false negative scans in 25 animals, and in the loop ligation study there were two false negative scans in 28 animals. The technique may have clinical application in such intestinal diseases as necrotizing enterocolitis in infancy in which early diagnosis of small areas of necrosis is currently difficult by clinical and radiologic methods.

The causes of postgastrectomy syndrome are multiple and differ in their relative frequency. Among the more unusual is intussusception of the small bowel into the stomach or into the jejunojejunostomy. We describe a patient with acute retrograde intussusception of the efferent loop into the jejunojejunostomy occurring 14 months after partial gastrectomy with Billroth II anastomosis. Several theories regarding etiology are mentioned, among them functional causes, mechanical causes and derangements in stomal function. In our case, the circulatory derangement might possibly be a causal factor. The diagnostic problems are discussed, and the importance of early diagnosis is pointed out. A chronic form of intussusception is mentioned by several authors. Often the differential diagnosis is difficult, but epigastric pain, vomiting--ultimately of blood--and a palpable mass, constitute a classic triad. X-ray and endoscopy are supplementary aids to the diagnosis. Several types of operative treatment have been used, but no operative procedure seems to be fully effective as a safeguard against recurrence.

A 67-year-old white man presented with bloody diarrhea and passed a 22-cm long segment of full-thickness sigmoid colon following a barium enema. He had advanced peripheral and cerebral vascular disease and had undergone pelvic irradiation for a bladder cancer five years previously. He recovered uneventfully from the bowel sloughage. This was apparently due to an intussusception of the sigmoid colon followed by the formation of adhesions between the edges of the adjacent viable bowel.

A case is presented of afferent loop intragastric intussusception diagnosed by gastroscopy 18 years after partial gastrectomy with retrocolic gastrojejunostomy. The intussusception was successfully reduced by means of the gastroscope. The symptoms were instantly relieved, with a symptom-free follow-up of 1/2 year. Provided that the intussuscepted segment appears viable it seems justified to aim initially to reduce jejuno-gastric intussusception with the aid of the gastroscope.

The history, clinical signs, and clinical pathology in a mature Holstein cow were consistent with a diagnosis of intussusception, but the lesion found during exploratory laparotomy consisted of a penetrating wire in the anterior duodenum.

We present a 14 year old girl with a two years' history of colicky abdominal pain associated with the palpation of a tumor in the left upper quadrant of the abdomen. During these two years, the pain and the tumor appeared and disappeared spontaneously several times. In the operation we found a jejunojejunal intussusception, the head being a sessile polyp placed 20 cm from the ligament of Treitz. The pathological examination showed a polyp formed by mucosa similar to the gastric one with chief and parietal cells. We discuss the clinical pictures that can be associated with this pathological entity in this uncommon localization in opposition to the more common settling in Meckel's diverticulum.

From our experience of malignant lymphoma in the large intestine and reviewing the Japanese literature, it might be concluded that this particular lesion was extremely rare, and was found predominantly in the right side of the colon. In contrast to the other malignant neoplasms in the large intestine, malignant lymphoma was found fairly often in children, which was accompanied by intussusception not infrequently.

The practicality, effectiveness, and safety of feeding very low birthweight infants (less than 1,300 gm) by continuous nasoduodenal infusion was assessed by comparison with continuous nasogastric feeding. The nasoduodenal group appeared to have a clear advantage over the nasogastric group for the overall period in terms of caloric intake (131 cal/kg/day vs. 106 cal/kg/day), average weight gain (16 gm/day vs. 10 gm/day), and safety. This advantage was even more striking in the first two weeks of life. A caloric intake of 120 cal/kg/day could be reached within 48 to 72 hours after tube placement in the nasoduodenal group but only after a week in the nasogastric group. Nasoduodenal feeding resulted in faster weight gain than comparable published data on conventional feeding, peripheral intravenous alimentation, and parenteral alimentation. There were no cases of aspiration associated with tubes placed in the duodenum whereas two cases of aspiration pneumonia were associated with tubes placed in the stomach. With the tip of the catheter in the duodenum, none of the complications reported with nasojejunal tubes (intussusception, perforation, or necrotizing enterocolitis) were seen, either in the initial pilot study reported here or in 50 additional infants.

An 81-year old man who had a plasmacytoma of the ileum presented with melena for which no bleeding site could be established before surgery. He developed intussusception and the tumor was located at laparotomy. Metastases to the skin and axillary lymph nodes were documented prior to his operation, to mesenteric lymph nodes at surgery and to intrathoracic lymph nodes and a substernal goiter at autopsy. The liver, spleen, bones and marrow were not involved by myeloma or amyloid. Immunoelectrophoresis demonstrated an Ig-A (lambda) monoclonal protein in the serum (with nondiagnostic serum zone electrophoresis patterns) and lambda light chains in the urine. Immunoflourescense of Ig-A (lambda) globulin was present in imprint preparations from the bowel tumor.
