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.

Eighty-one patients with proven intussusception were treated at the Cincinnati Children's Hospital from 1970-1974. One died. Seven of these had ileo-ileal intussusception, all treated surgically. Seventy-four had colonic components of their intussusceptions. In 58 of these patients (78%), reduction was attempted at barium enema, successfully in 32. Hydrostatic reduction was abandoned and the patient operated upon when the intussusception was not pushed out of the colon, when barium failed to reflux into several loops of ileum, or when there was a large persistent filling defect in the cecum or terminal ileum. Primary operation without barium enema was done in 16 patients. The appearance of intestinal obstruction by abdominal x-ray seemed to give the best warning about the complicated, incarcerated, or gangrenous intussusception. Primary operation is, therefore, advised for the patient with intussusception if there is x-ray evidence of intestinal obstruction. The age of the patient and the duration of his symptoms do not seem important in this regard, except as they correlate with peritonitis or obstruction. For the patient without peritonitis or intestinal obstruction, attempted reduction of the intussusception at barium enema seems safe and effective, regardless of the patient's age or duration of his symptoms.

Two cases of obstruction of the bypassed small intestine after jejunoileal shunt for obesity are presented. These cases illustrate the possible failure of radiologic visualization of the obstructed bowel since no gas traverses this bowel, as well as two of the possible causes-internal herniation and volvulus. A third cause, intussusception of the blind loop into the colon, has been reported. Obstruction of the bypassed bowel demands surgical intervention and could lead to perforation and peritonitis if untreated. Its prevention involves the closure of all mesenteric defects at the original operation. Surgeons should be aware of the possibility of these conditions in any patient who has had a small-bowel bypass operation.

15 cases of intussusception with presenting symptoms of more than 24 h duration were studied by sonography and Doppler. The aim of the study was to determine the validity of the sonographic criteria of peritonitis and bowel ischaemia in order to reduce the risk of colonic perforation and to increase confidence in achieving a successful hydrostatic reduction. The results were reviewed retrospectively and cases divided into 2 groups. Cases in group 1 were reducible by barium enema while those in group 2 required surgical intervention. Sonographic features of peritonitis were absent in all cases of group 1 and 3 cases of group 2. These 3 cases were reduced manually at surgery while the other 5 cases in group 2 with positive features of peritonitis required bowel resection. Blood flow was documented by colour flow Doppler in all cases except the 3 cases with gangrenous bowel in group 2. When sonographic features of peritonitis and loss of blood flow to the intussusception are present in late intussusception, surgical intervention is required. On the other hand, enema reduction should be pursued when such features are absent.

Gas has replaced barium as the preferred medium for enema reduction of intussusception in tertiary pediatric institutions. Previously, adverse clinical features that in combination predicted a low likelihood of successful reduction using barium had been identified and used to select patients suitable for attempted enema reduction. This study examines whether these adverse features are equally applicable to gas reduction of intussusception. For any given number of adverse features, gas enema reduction was found more likely to be successful than barium reduction and, in the absence of clinical evidence of peritonitis, multiple adverse features probably do not represent a contraindication to attempted gas enema reduction.

Gastroendoscopy was performed on 111 horses (1 to 22 years old) that had signs of abdominal discomfort of variable duration and severity. At least 1 episode of colic had been observed within 48 hours of examination in 31 horses. Recurrent episodes of colic were observed in 28 horses within 2 to 10 days of examination, 31 horses within 11 to 30 days, 12 horses within 31 to 60 days, and in 9 horses at more than 60 days after the initial examination. Gastric ulceration was found in 91 of 111 horses examined. Other abnormalities involving the gastrointestinal tract or other abdominal viscera were not found on examination in 57 of 91 horses with gastric ulcers. The most frequent concurrent abnormalities found in the remaining 34 horses with gastric ulcers were impaction of the large colon (n = 6), colonic tympany (n = 6), peritonitis (n = 6), gastric impaction (n = 4), ileocecal intussusception (n = 3), small-colon impaction (n = 4), and proximal enteritis (n = 2). Thirteen horses with gastric ulceration underwent abdominal surgery, and in 5 horses, lesions were not found at surgery. Gastric ulceration was determined to be the primary cause of colic in 31 horses on the basis of the lack of other abnormalities, clinical response to treatment with histamine type-2 receptor (H2) antagonists, and confirmation of improvement or resolution of gastric ulceration via endoscopy. Gastric ulceration was the suspected cause of colic in 26 other horses on the basis of the lack of other abnormalities, severity of lesions, and clinical response to treatment with H2 antagonists.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of intussusception in a 6 month old with lethargy as the initial and predominant system is presented. Children presented to the Emergency Department with otherwise unexplained lethargy should have intussusception as part of the differential diagnosis. A plain film of the abdomen should be obtained. A rectal exam should be done, and a stool checked for occult blood. Radiologic and surgical consultation should be sought simultaneously. Delay in diagnosis and treatment may be associated with decreased success rates of reduction by barium enema, and increased rates of complications of perforation, peritonitis, sepsis, and death.

The authors describe several cases of intussusception in children and one in an adult, paying attention to the underlying pathology, also in children. This must be kept in mind at the radiological examination (so called "leading points") and at the operation. Different causes are Meckel's diverticulum, ectopic pancreatic tissue, tumours. Air insufflation (= chinese method) could be safer and in case of perforation it would be less dangerous. Surgery shall be undertaken in late diagnosis, difficult or impossible reductions by enema and signs of perforation or peritonitis.

High mortality rates associated with mesenteric ischaemia are a tremendous challenge. We reviewed 43 patients admitted to Chang Gung Memorial Hospital between 1981 and 1988. A total of 24 patients (55.8%) had thrombosis or embolus of the superior mesenteric artery, five patients (11.6%) had superior mesenteric vein thrombosis, and 14 patients (32.6%) had non-occlusive infarction. Patients with mechanical obstructions (volvulus, intussusception, tumour compression, aortic dissection) causing mesenteric ischaemia were excluded. The initial symptoms were not specific before signs of peritonitis presented. The tetrad of leucocytosis (88.4%), metabolic acidosis (88.6%), hyperamylasaemia (46.9%) and elevated phosphate (33.3%) was noted to be significant. There was a high association with previous cardiovascular diseases (78.2%). The plain abdominal X-ray, which was the most frequently used investigative tool, showed suggestive but non-specific findings. A total of 38 patients (88.4%) were operated upon. In six patients (14%) the exploratory laparotomy was open and closed because the bowel gangrene was too extensive. The total mortality rate was 55.8%. To improve prognosis, clinical awareness of the problem should be raised and the use of mesenteric angiography should be encouraged in an attempt to obtain an early diagnosis.

In a 14-year period 15 cases of free perforation of the small bowel in adults were treated in our department. In two patients perforation was caused by a foreign body and in six by each of the following: duplication of the small bowel, Hodgkin's lymphoma, vasculitis and steroid treatment, intussusception, adhesions, diverticulum. All patients presented with the signs of diffuse peritonitis. One patient died before surgery. Of the 14 patients operated upon, 10 underwent resection and primary anastomosis and four suturing of the perforation. In six cases the etiology remains unknown even after surgical intervention and pathological examination. The mortality rate of the 14 operated patients was 7.1%. 78.5% of the patients were operated on within 24 hours of onset of symptoms, and early surgery is considered to be the most important factor in the low mortality rate achieved in this series.
