Emergency medicine bedside ultrasound diagnosis of intussusception in a patient with chronic abdominal pain and unrecognized Peutz-Jeghers syndrome.

An adult patient presented to the Emergency Department (ED) with abdominal pain caused by intussusception. The diagnosis had not been made despite several prior evaluations for episodes of similar symptoms. The diagnosis was finally made by bedside ultrasound performed by the treating physicians in the ED. The patient's underlying condition of Peutz-Jeghers Syndrome with intestinal polyps was also previously undiagnosed. The discussion reviews and compares clinical aspects of intussusception in adults and children. Sonographic findings of intussusception and their pathological basis are described, and the accuracy of sonography in the diagnosis of intussusception is reviewed.

[Intrauterine intussusception causing intestinal atresia during pregnancy].

CASE REPORT: A case of intrauterine intussusception causing ileal atresia is reported. The neonate presented at the age of one day with bilious vomiting, failure to pass meconium and progressive abdominal distension. A clinical diagnosis of intestinal obstruction was made, and was confirmed by plain abdominal radiographs. At laparotomy, atresia of the terminal ileum was found. The lumen of the resected distal segment contained an intussusceptum. The blind ends were resected and an anastomosis was performed. Recovery was uneventful. COMMENTS: Intrauterine bowel intussusception is a rare clinical entity. When intussusception occurs in the foetus and the time elapsed is enough to allow for gangrene and resorption of the intussuscepted portions of the bowel, intestinal atresia may result. CONCLUSIONS: The careful examination of the distal blind end of the ileum aids to obtain a correct classification and etiologic diagnosis of the atresia.

[Iterative intestinal intussusception and appendiceal mucocele in an infant with mucoviscidosis].

UNLABELLED: Cystic fibrosis is a common and potentially life-threatening hereditary disease which can affect numerous organs, particularly the digestive tract. CASE REPORT: A 4.5-year-old boy exhibited two little known clinical manifestations: an appendiceal mucocele and repeated intussusceptions. In spite of an appendectomy, intussusception relapsed and an ileocolic resection was necessary 2 years later. DISCUSSION: Appendiceal diseases in cystic fibrosis represent a large spectrum, ie, distention on the appendiceal lumen, engorged with sticky mucous matter, which becomes an appendiceal mucocele, peritonitis with an appendiceal perforation due to delayed diagnosis since acute appendicitis is difficult to diagnose in these patients. Intussusception is rarely observed in cystic fibrosis. CONCLUSION: Appendiceal mucocele could be a cause of intussusception. If an appendectomy is performed, resection of a part of the cecum, around the appendix, could be useful in preventing again mucocele formation.

[Hypertensive manifestation of an acute intestinal intussusception].

BACKGROUND: Hypertension may be associated with intussusception. CASE REPORT: An 8-month-old infant showed the following symptoms: lethargy, vomiting and hypertension. Abdominal ultrasound suggested the diagnosis of intussusception, which was confirmed by barium enema. The hypertension resolved after the intussusception was reduced. CONCLUSION: Intussusception should be considered a diagnostic possibility in infants who show a history of vomiting and in whom lethargy and systematic hypertension are noted. This case re-affirms the diagnostic usefulness of abdominal ultrasonography.

A simple and safe technique for pneumatic reduction of intussusception.

BACKGROUND: Pneumatic reduction has a higher success rate and lower incidence of complications compared to barium enema and hydrostatic reductions. What is deterrent to its common use is the cumbersome technique. Our aim is to develop a simple technique that can be used in any hospital with locally available facilities. METHODS: An intercostal drainage bottle and an enema can were used to pass air into the rectum at a controlled pressure determined by the height of the enema can. Water running in from the enema can displaces the air in the intercostal drainage bottle into the rectum effecting the reduction of intussusception. RESULTS: This system was tried in 12 patients. Successful air delivery was obtained in all cases. In two cases, the intussusception could not be reduced. Laparotomy revealed these to be ileoileal intussusceptions. CONCLUSION: The technique described is easy to assemble, safe and effective. We recommend it for regular use in pneumatic reduction of intussusception.

Intussusception.

Intussusception is the invagination of one portion of the intestine into another and is the most common form of intestinal obstruction in infants. This report reviews the clinical presentation and diagnostic and treatment options available for intussusception. The etiologies of childhood intussusception are discussed. Details and literature review are provided on the advantages and disadvantages of ultrasonography, barium enema, air contrast enema, and surgery in the diagnosis and treatment of intussusception.

A high incidence of intussusception in Japan as studied in a sentinel hospital over a 25-year period (1978-2002).

The development of second-generation rotavirus vaccines requires knowledge of baseline incidence rates for intussusception in infants prior to vaccine introduction. To obtain such estimates we reviewed clinical records in a hospital that served as the major provider of paediatric beds in a local community in the northern part of Japan. During the 25-year period (1978-2002), there were 91 hospitalizations due to radiologically confirmed intussusception in children <5 years of age, of which 45% were <1 year of age. Assuming that all children with intussusception in the area had been admitted to this hospital, there were an average of 185 and 78 hospitalizations per 100000 person-years for children <1 year old and 5 years old respectively. There was period-to-period variability with no long-term secular trend in the incidence of intussusception. The incidence rate in Japan was among the highest thus far reported, providing further evidence of geographic variability.

Lack of association between intussusception and oral polio vaccine in Cuban children.

Two exploratory investigations found an increased risk of intussusception after oral polio vaccine (OPV). A large, national, population-based study was undertaken in Cuba to investigate a possible association. Three hundred and thirty-five cases of intussusception in children under 2 years of age occurring in 1995-2000 were identified and their OPV records retrieved. The relative incidence (RI) of intussusception in defined periods up to 42 days after OPV in children under 1 year was estimated using the self-controlled case series method, controlling for age and season. The RI was not significantly raised in any of the time intervals examined within the 0-42 day period after OPV. For the period 0-42 days as a whole the RI was 1.11, 95% CI 0.74-1.67. This study does not support the hypothesis that OPV causes intussusception.

Does oral polio vaccine cause intussusception in infants? Evidence from a sequence of three self-controlled cases series studies in the United Kingdom.

BACKGROUND: The use of live oral poliomyelitis vaccine (OPV) has led to the elimination of poliomyelitis disease in many countries since licensure in 1960. The discovery of an increased risk of an intestinal obstruction known as intussusception following live rotavirus vaccination raised questions about the possibility of a link between live OPV and intussusception. METHODS: Three self-controlled case-series studies were carried out. The first was exploratory and included 218 intussusception episodes from hospital admissions data linked to vaccination records in the Thames region. The two subsequent studies, which used further hospital admissions data and the General Practice Research Database (GPRD) included 107 and 198 episodes respectively and were used to test hypotheses generated in the first study. RESULTS: In the exploratory study risk periods of up to 6 weeks after each dose were examined. The only period with some evidence of an increased risk was the 14-27-day period after the third dose (relative incidence (RI) = 1.97, p = 0.011). The second hospital admissions study and the GPRD study showed no evidence of an increased relative incidence in any putative risk period and did not confirm the increased risk in the 14-27-day period after dose 3 with a combined RI of 1.03. CONCLUSIONS: The sequence of studies does not support the hypothesis that OPV causes intussusception. The increased RI in the first study may be explained as a chance finding due to the number of risk periods examined and highlights the need for caution when looking at many risk periods without an a priori hypothesis.

Follicular lymphoid hyperplasia simulating intussusception in a 6-year-old boy: clinical, radiological and histopathological findings.

We report the case of a 6-year-old boy who initially presented with recurrent abdominal pain. Diagnostic imaging, including ultrasound and CT, showed findings typical of an ileocecal intussusception with abdominal lymphadenopathy. Sonographically, the morphological appearance of the intussusception did not change during a 4-week follow-up period. Surgery was performed on the tentative diagnosis of a tumour versus lymphoma. Upon laparatomy, intussusception was ruled out and a large, broad-based tumour of the caecum was palpable. The histopathology after ileocecal resection revealed follicular lymphoid hyperplasia. Where there is radiological suspicion of an intussusception in children with no or insignificant symptoms, follicular lymphoid hyperplasia should be included in the differential diagnosis.

Delta-F508 cystic fibrosis mutation is not linked to intussusception: implications for rotavirus vaccine.

OBJECTIVE: To determine whether the cystic fibrosis (CF) delta-F508 gene mutation predisposes to intussusception, and so selects infants who should not receive rotavirus vaccine. METHODS: Stored neonatal screening blood spots, retrieved from 81 infants with intussusception and from 79 controls, were tested for the presence of the CF delta-F508 gene mutation. RESULTS: Prevalence of the mutation was similar in blood specimens from intussusception patients and from controls. CONCLUSION: Testing for the CF delta-F508 mutation at birth is unlikely to identify infants predisposed to intussusception, and therefore is not relevant to rotavirus vaccine programs.

Duodenojejunal intussusception secondary to hamartomatous polyps of duodenum surrounding the ampulla of Vater.

Duodenojejunal intussusception is a rare pediatric emergency. A case of duodenojejunal intussusception secondary to hamartomatous polyps of the second portion of duodenum in a 10-month-old boy is reported. Surgical excision of the polyps and reduction of the intussusception were performed. Pathologic examination found hamartomatous polyps. This is the third case report of children in literature, but this is the first case of a child with intussusception surrounding the ampulla of Vater and a successful excision performed without damaging the ampulla of Vater.

Familial intussusception.

Intussusception, although a common cause of emergency in pediatric surgery, occurs rarely in more than one member in the same family. A genetic predisposition has been suggested in some cases. The authors report on 4 members of a family in 3 generations who suffered each an episode of idiopathic ileocolic intussusception over a period of 52 years. This is the only instance we found after reviewing 99 cases of intussusception in our hospital during the last 10 years. There was no recurrence of intussusception in any case, and no underlying anatomic abnormality was found in the 2 patients who underwent surgery.

Cecal amputation within the right ventral colon for surgical treatment of nonreducible cecocolic intussusception in 8 horses.

OBJECTIVES: To report a surgical technique for treatment of nonreducible cecocolic intussusception and outcome in 8 horses. STUDY DESIGN: Retrospective study. ANIMALS: Eight horses with nonreducible cecocolic intussusception treated by cecal amputation through a right ventral colotomy. METHODS: Data were obtained from medical records and telephone conversations by using a standardized questionnaire. The large colon was exteriorized and, if necessary, evacuated of its contents through a pelvic flexure enterotomy. A second colotomy was made on the ventral surface of the right ventral colon (RVC) centered over or immediately distal to the intussusceptum. In most horses, attempts to manually reduce the intussusception by pushing the cecum from within the RVC through the cecocolic orifice were unsuccessful. Invaginated cecum was then pulled into the RVC and amputated; the cecum was either ligated with umbilical tape or sutured proximal to the site of amputation. After amputation, the remainder of the invaginated cecum was reduced. After further resection to healthy tissue, the typhlectomy was closed with a double-inverting suture pattern. RESULTS: The median horse age was 2 years (range, 1 to 8 years). Duration of colic ranged from 6 hours to 6 months. Median surgical time was 180 minutes (range, 135 to 300 minutes). Median duration of antibiotic therapy was 7 days (range, 5 to 14 days). Median duration of hospitalization was 12 days (range, 6 to 21 days). All horses survived to hospital discharge. One horse died 3 months postoperatively; however, the remainder survived (median survival, 30 months; range, 6 to 96 months) and returned to or exceeded previous function. CLINICAL RELEVANCE: Despite some contamination during surgery, horses with nonreducible cecocolic intussusception that underwent this method of surgical treatment had a good prognosis.

Intrauterine intussusception presenting as fetal ascites at prenatal ultrasonography.

Intrauterine intussusception, an uncommon cause of bowel obstruction, has rarely been detected by prenatal ultrasonography. We report two cases of intrauterine intussusception after gestation, which presented as isolated fetal ascites at 30 weeks of gestation by ultrasonography. In case 1, on the follow-up ultrasonography at 32 weeks of gestation, the previously observed ascites had disappeared, whereas the echogenicity of the bowel was increased without any sign of dilation, suggesting the presence of meconium peritonitis. The fetus was delivered at 39 weeks. In case 2, however, the amount of fetal ascites became increased, and the fetus was delivered at 34 weeks of gestation. After delivery, both infants were surgically explored with resection of the ileum with end-to-end anastomosis because of intrauterine intussusception and ileal atresia. From the experience of these cases, we suggest that the ultrasonographic finding of isolated or transient fetal ascites might contribute to the early diagnosis and management of intrauterine intussusception.

Intussusception complicated by bowel perforation during hydrostatic reduction.

Most perforations of the bowel during attempt at hydrostatic reduction of intussusception occur in an area of localised infarction in the normal transverse or left colon. An animal model of intussusception was used to find indications for the cause of this phenomenon. We submitted the intussuscipiens of 10 strangulated intussusceptions in 6 dogs to a histological examination. In 6 of 10 intussusceptions we found ischaemic changes in the mucosa of the intussuscipiens. In 3 cases these lesions were multiple. All lesions were found in locations where there was a close contact between the intussusceptum and the intussuscipiens. We did not find signs of impaired circulation of the whole intussuscipiens. We conclude that our findings give an indication that perforation of the intussuscipiens during attempt at hydrostatic reduction occurs through areas of localised ischaemic infarction on the basis of direct pressure by the intussusceptum.

Idiopathic postoperative intussusception.

During the last 11 years idiopathic postoperative intussusception developed in ten children. The incidence was 5.5% of all the intussusceptions. The age ranged from three months to ten years and the interval between two surgical procedures differed from three to eight days. Only one of the patients presented the classical signs of intussusception. In nine of them, the obstructions were in the small bowel. Nine of the ten intussusceptions needed simple manual reduction. Postoperative recovery was uneventful.

Intussusception in a premature infant simulating necrotising enterocolitis.

Intussusception in older infants is manifested by bloody stools, colicky abdominal pain and a palpable abdominal mass. In neonates the symptoms are often restricted to vomiting, guaiac positive stools and abdominal distension. These symptoms closely mimic necrotising enterocolitis. Surgical treatment of necrotising enterocolitis should be postponed until perforation of the gastrointestinal tract has occurred, whereas, prompt surgical treatment is recommended for intussusception. We report a case of intussusception that simulated necrotising enterocolitis in a 740 grammes premature infant in the second week of life. The clinical and radiographic features are described and the difficulty in distinction between the two conditions is emphasised. Neonatologists and paediatric surgeons should always include intussusception in the differential diagnosis of abdominal distension and guaiac positive stools in small premature infants.
