Intussusception in the Syrian golden hamster.

Of a series of ninety-six young male Syrian Golden hamsters, 13% developed lethargy, anorexia, diarrhoea and colocolic intussusception when their diet was changed from a basal laboratory-grade rodent chow to a nutritionally complete semi-purified diet. Histologically, the colon of the hamsters with intussusception had markedly reduced mucus production. Plasma levels of gastric inhibitory polypeptide (GIP) were reduced 80% (P less than 0.01) but peptide tyrosine/tyrosine and enteroglucagon in plasma were increased 290 and 526% respectively in hamsters with intussusception. Variations in dietary fatty acid composition had no effect but intussusception was not observed after changing the dietary carbohydrate from sucrose to starch.

Intussusception. A case that suggests a new cardinal symptom--lethargy.

Intussusception is an uncommon condition, but it is the most frequent cause of bowel obstruction in infants and children aged 3 months to 5 years. If undiagnosed, it can result in bowel necrosis, perforation, and even death. Four cardinal signs and symptoms (abdominal pain, rectal bleeding, vomiting, and abdominal mass) are described in patients with intussusception, but these manifestations are not always present and their absence may lead to misdiagnosis. Lethargy might be considered a fifth cardinal symptom. As demonstrated in this case, lethargy may be a significant presenting feature in an infant with no history of abdominal pain, and in association with the other cardinal symptoms, it may be an early indication of a significant illness such as intussusception. Awareness of this association may result in an earlier diagnosis and an improved outcome in patients with intussusception.

Tropical paediatric intussusception--is it a different disease entity?

The presentation of intussusception in children in Zaria, Nigeria has been studied with the aim of identifying any features that may differentiate it from that which obtains in temperate countries. Our data reveal no difference in age of peak incidence, sex ratio, absence of preceding upper respiratory infection or lack of significant seasonal variation. However, there is an unusually high incidence (41%) of caecocolic intussusception. It is believed that this may account for other observed features, such as the low occurrence of constipation and other evidence of intestinal obstruction, and the relatively high incidence of "painless" intussusception and sub-acute or chronic intussusception. Twenty-nine per cent of the patients had only one or two of the usual diagnostic features of the disease and this contributed to delayed diagnosis. In all but two patients the condition was idiopathic and there was no evidence to implicate bacterial enteritis or parasitic infestation in the aetiology of the disease.

Intussusception in infants and older children: a comparison.

The clinical features and operative findings in 37 infants and 29 older children with intussusception seen over a 10-year period were compared and contrasted. While most of the children presented acutely, 28% of older children had chronic intussusception compared with 5% in infants. Only about a third of all children had the four classical features of abdominal pain, vomiting, abdominal mass and bloody stool; the rest had two or three of the above features. Pain and palpable abdominal mass were more common features in older children while abdominal distension, constipation and diarrhoea were more prominent in infants. Fifty-four per cent of intussusceptions in infants were entero-colic while in older children 69% were colonic. All the intussusceptions in infants were idiopathic while in 14% of older children there were predisposing causes. Resection for gangrene/perforation was required in 30% of infants compared with 7% of older children.

Laparoscopic diagnosis and treatment of small bowel obstruction caused by postoperative intussusception.

Small bowel obstruction is a common problem, especially for patients who have had previous abdominal surgery possibly complicated by postoperative adhesions. In contrast to adhesions, postoperative intussusception is an unusual cause of small bowel obstruction. We report a case of small bowel obstruction that occurred one month after antrectomy for duodenal ulcer with massive bleeding. Laparoscopic surgery was attempted after conservative treatment failed. A segment of jejunojejunal intussusception about 50 cm below the ligament of Treitz was identified and laparoscopic reduction of the intussusception was performed. The patient had an uneventful postoperative course and remained asymptomatic at 10-month follow-up. Although not frequently encountered, postoperative intussusception should be considered a possible etiology in patients with postoperative small bowel obstruction. In experienced hands, the laparoscopic approach offers a feasible option for correct diagnosis and appropriate treatment in this situation.

Complete appendiceal intussusception induced by primary appendiceal adenocarcinoma in tubular adenoma: a case report.

A case of complete intussusception induced by appendiceal carcinoma is reported. The patient was a 49-year-old man complaining of rectal bleeding. Barium enema and colonoscopy revealed a cecal polyp; it was interpreted as an inverted appendix with a tumor. Computed tomography showed an invaginated appendix into the cecal cavity. During surgery, the appendix was found to be inverted completely into the cecum; ileocecal resection with regional lymph node dissection was performed. Microscopic examination revealed well-differentiated adenocarcinoma in tubular adenoma. Diagnosis of intussusception with carcinoma of the appendix is often difficult because appendiceal carcinoma with intussusception of the appendix is a rare condition. Although this condition can be diagnosed by radiographic imaging or colonoscopy, computed tomography has also been useful. The clinical manifestation of appendiceal intussusception with primary appendiceal tumor resembles a large cecal polyp, but its treatment differs greatly. Failure to recognize this condition may result in unexpected complications such as consequent peritonitis in case of endoscopic removal.

Ileocecal intussusception of small-bowel lymphoma: diagnosis by colonoscopy.

Intussusception is rare in adults. There is little information on the role of colonoscopy in colonic intussusception. We report, to our knowledge, the first adult case of small-bowel lymphoma causing ileocecal intussusception in which the diagnosis was made by colonoscopy. Colonoscopy has a useful role in the diagnosis and management of ileocecal intussusception.

The diagnosis and treatment of adult intussusception.

BACKGROUND: Intussusception in adults is often diagnosed on computed tomography (CT), and the optimal treatment of this entity is not universally agreed upon. We report our experience in an attempt to clarify the usefulness of CT scan and the optimal treatment of this entity. STUDY: Seven cases of adult intussusception were encountered at our institute between 1991 and 2001. Data related to presentation, diagnosis, treatment, and pathology were analyzed. RESULTS: Preoperative diagnosis was made in four patients by CT scan and/or ultrasonography. Two patients had colonic cancer and one had jejunal cancer. Three of four patients with small bowel intussusception underwent reduction before resection and the other one underwent resection without reduction because of severe ischemic bowel. CONCLUSIONS: The CT scan is most useful in making the diagnosis of intussusception. Colonic lesions should be resected without reduction. Small bowel lesions should be reduced only in patients in whom a benign diagnosis has been strongly suggested preoperatively or in patients in whom resection may result in short gut syndrome.

Duodenojejunal intussusception secondary to hamartomatous polyp of Brunner's glands.

A case of duodenojejunal intussusception secondary to a large hamartomatous polyp of Brunner's glands was reported in a 15-year-old girl. Despite a great preponderance of ileocolic intussusception in childhood, this is the first reported case of duodenojejunal intussusception occurring in that age group. The diagnosis was not made by clinical examination; complete duodenal obstruction was shown in upper gastrointestinal series and by endoscopy. The intussusception was reduced manually at laparotomy, and the polyp was excised. Pathological examination revealed a preponderance of normal-appearing Brunner's glands in the tumor, consistent with the diagnosis of Brunner's gland hamartoma.

The role of abdominal x-rays in the diagnosis and management of intussusception.

The management of intussusception requires early diagnosis and reduction with either barium enema or surgical intervention. Supine and erect abdominal radiographs are often obtained prior to ordering a barium enema. In many pediatric centers, the critical, initial interpretation of these radiographs is made by nonradiologists and, in most instances, by pediatric emergency physicians. We determined the sensitivity and specificity of abdominal radiographs in diagnosing intussusception when interpreted by these physicians. Six full-time pediatric emergency physicians evaluated 126 radiographs from 42 patients with intussusception, 42 in whom the disease was clinically suspected but ruled out, and 42 in whom the final radiology report was "normal." These were presented to pediatric emergency physicians in a blinded, randomized sequence without any additional clinical information. These physicians then identified patients for whom they would proceed to barium enema. The mean sensitivity was 80.5% (range, 71-93%), and the mean specificity was 58% (range, 48-69%). This compares favorably to the sensitivity of signs and symptoms, and we conclude that plain and upright abdominal films are a useful adjunct for the clinician evaluating patients for suspected intussusception.

Postoperative intussusception: increasing frequency or increasing awareness?

Postoperative intussusception in children is a rare but well recognized phenomenon. The diagnosis is often delayed due to the protean manifestations of the disorder (ileus, distention, and nausea and vomiting) which, when encountered shortly after an abdominal operation, usually result in a low index of suspicion because they are common after laparotomy. Experience with two cases of postoperative intussusception within 24 hours heightened our index of suspicion. Review of our records indicated we had diagnosed and treated postoperative intussusception in 14 children during the preceding 4 years. Patient ages ranged from 4 months to 12 years (mean 39 months, median 20 months), and symptoms appeared on postoperative days 3 to 36 (mean 10 days, median 6 days). Initial operations included excision of a retroperitoneal or abdominal tumor (five cases), Nissen fundoplication and gastrostomy (three), ileal resection (two), Ladd procedure (one), Duhamel operation (one), and operative reduction of ileocolic intussusception (the two most recent cases). Eleven patients had appendectomy (five by the inversion technique), and three had placement of a transgastric small bowel feeding tube. Nine children had had either barium enema or upper gastrointestinal studies because of the postoperative suspicion of obstruction; one patient had both. Diagnostic studies were not done in four patients. Operative reduction was successful in all but one child, who required bowel resection.

Adult intussusception due to inverted Meckel's diverticulum: laparoscopic approach.

Nowadays, laparoscopy appears to be an attractive alternative to conventional surgery in the management of small bowel obstruction. Adult intussusception is an unusual cause of intestinal obstruction, and a wide range of pathologic conditions can result with intussusception. In this report, we present a very rare case of intussusception secondary to inverted Meckel's diverticulum in an adult who underwent laparoscopic surgery. The diagnostic modalities and surgical management of intussusception are discussed.

Ultrasound of intussusception with lead points.

Ultrasonography of 4 cases of intussusception in children with proven lead points were reviewed retrospectively. The lead points were due to lymphosarcoma, inverted Meckel's diverticulum, jejunal polyps and an inverted appendiceal stump. The lead points form a complex mass in the centre of the intussusception in both transverse and longitudinal sections, distinct from primary intussusception. The presence of such ultrasonographic findings are suggestive of secondary intussusception with a lead point and surgical reduction rather than hydrostatic reduction should be considered.

Tropical intussusception in adults.

In contrast with the incidence in Britain and the United States, about 50% of intussusceptions in Sri Lanka occur in adults, the maximum age incidence being in the fourth decade. Seventy-six cases of intussusception in adults are analysed in this paper, 62 of which were of the caecocolic type, which though only rarely described in the West, have also been frequently reported from other tropical countries. The clinical picture was characteristic, and a mass was palpable in 90% of the patients, facilitating diagnosis without ancillary investigations. On the basis of the histological examination of resected specimens it is concluded that amoebic granulomatous formation in the dependent "diverticulum" of the caecum is the predisposing cause of the caecocolic intussusception, accounting for the chronicity of a large number of cases. Irrespective of the duration of the illness, gangrene did not occur in any of the cases if this type, although resection was occasionally required on account of irreducibility. In view of the proliferation of fibrous tissue in the wall of the caecum, complete evagination of the intussusception can only be achieved by surgical exploration and manipulation, the results of which are excellent.

Jejunogastric intussusception: therapeutic options.

Acute jejunogastric intussusception is a rare complication of gastric surgery. It presents considerable difficulties in diagnosis unless the index of suspicion is high. Four cases of acute retrograde jejunogastric intussusception are reported. They were managed surgically after diagnosis had been confirmed by upper gastrointestinal contrast studies. In situ resection of the distal portion of gangrenous intussusceptum was performed in one case, while the intussusception could be reduced manually in the other three cases. The importance of early diagnosis in preventing avoidable morbidity and mortality has been stressed. In situ resection is recommended as the method of choice for the management of irreducible, gangrenous intussusception.

The cost benefit of changing protocols in the management of intussusception.

BACKGROUND: At a time when pressure is being applied to healthcare systems to reduce costs and improve efficiency, both the medical and financial implications of changing practices need to be documented. METHODS: A review was undertaken of 703 patients with intussusception, treated during a 10-year period from 1983. RESULTS: This review showed that changes to the protocol for the management of intussusception have not only benefited the patient by reducing the morbidity and the operative rate, but also have led to a reduction in the length of hospital stay, providing significant cost savings to the health system. The reduction in the operative rate accounts for an estimated annual saving at the Royal Children's Hospital of $139,000. CONCLUSIONS: Improvements in the management of intussusception have resulted in significant reductions in the costs of treatments. The recent diagnosis-related group casemix funding arrangements mean, however, that the Royal Children's Hospital benefits more financially from inappropriate operative management of intussusception, than from non-operative management. Funding arrangements should not discourage optimal treatment.

Different management options for anaphylactoid purpura with intussusception: a case report.

Intussusception is the most common surgical indication of anaphylactoid purpura. About 50% of cases are of the ileo-ileal type. Surgical intervention, rather than radiologic reduction, is preferable for older children suffering from anaphylactoid purpura with intussusception, where a lead point lesion is often found. The authors report a case of anaphylactoid purpura with intussusception with spontaneous reduction, and postulate that subsequent to relieving bowel-wall edema using antihistamine and steroid therapy, the ileo-ileal intussusception may spontaneously reduce.

Atypical characteristics of a group of children with intussusception.

We describe the characteristics of a group of 140 children with intussusception. They differed strikingly from the classical picture of intussusception given in textbooks and in publications concerning large series. We found a low incidence of intussusception especially in infants and young children. There were far more children of older ages, the delay in diagnosis was significantly longer and there was a very high percentage of leading points. These factors explained our low hydrostatic reduction rate. The weight of most children was under the fiftieth percentile. The percentage of small bowel intussusceptions was somewhat higher. These differences are important in the light of early diagnosis and evaluating the results of treatment.
