Intussusception in children: 11-year experience in Vladivostok

Idiopathic intussusception is an important abdominal emergency in infancy and childhood. The nonoperative management by air enema has always been the standard of care in Russia. Our purpose is to assess our reduction rate and the rate of complications. We performed a retrospective analysis of all intussusception cases seen at the Department of Paediatric Surgery from 1994 to 2005. The data obtained included age, sex, clinical presentation, diagnostic procedures, mode of treatment, and results. Patients included 280 children from 1 month to 14 years of age. Eighty-one percent of children were under age 1 year old, 61% were boys. The duration of symptoms before treatment was less than 18 h in 65%, 18-24 h in 21%, and more than 24 h in 14% of patients. The successful reduction rate was 86.1%. One patient with a duration of symptoms more than 24 h experienced colon perforation. Thirty-nine patients underwent surgery and, among these, abnormalities in the intestinal wall required resection in 12 cases. An association between the duration of symptoms and the outcome of the non-surgical treatment was present; non-surgical reduction was successful in 97.3% in the group with the duration of symptoms less than 18 h, 86.4% in 12-24 h, and 33.3% in more than 24 h. Air enema is a safe and effective approach for uncomplicated intussusception reduction with a high success rate, but the duration of symptoms directly increases the complication rate.

Intussusception: Trends in clinical presentation and management

The association of a rotavirus vaccine and intussusception has renewed interest in understanding the incidence, clinical presentation and outcome of intussusception. A retrospective chart review of all patients diagnosed with intussusception at Royal Children's Hospital, Melbourne over a 6.5-year period (1 January 1995-30 June 2001) was conducted using patients identified by a medical record database (ICD-9-CM code 560.0 1993-1997; ICD-10-CM code 56.1 1998-2001). Patient profile, clinical presentation, diagnosis methods, treatment and outcome were analyzed and compared to data previously reported on children with intussusception at the same hospital during 1962-1968. The hospitalization rate for primary idiopathic intussusception increased marginally from 0.19 to 0.27 per 1000 live births during the period 1962-1968 to 1995-2001. Most patients (80%) were <12 months of age (median age 7 months, range 2-72 months). The combination of abdominal pain, lethargy and vomiting was reported in 78% of infants. Air enema confirmed the diagnosis of intussusception in 186 of 191 cases (97%) and air reduction was successful in most cases (82%). Factors associated with increased risk of intestinal resection included abdominal distension (32%), bowel obstruction on abdominal X-ray (27%) and hypovolemic shock (40%). No mortality was observed in the present study. Over the past 40 years at Royal Children's Hospital, Melbourne the hospitalization rate due to primary idiopathic intussusception has marginally increased from 0.19 to 0.27 per 1000 live births. Diagnosis and treatment using air enema has been highly successful, resulting in a reduction in patients requiring surgery and reduced hospital stays.

Intussusception in Adults

To review clinical, radiological and histopathological findings of adult intussusception and its management, 18 adult patients who had been treated surgically because of intussusception were reviewed. Of the patients, 5 (27.8%) had idiopathic intussusceptions, while the other 13 (72.2%) had a definable intraluminal pathology. The site of the intussusception was more common in the small bowel (83.3%) than the colon (16.7%). Ultrasonography and computed tomography were successful in demonstrating “target lesion” in 80% and 75% respectively. Patients with idiopathic intussusception were treated with simple reduction, while the others underwent segmental resection because of the possibility of malignant tumour. In contrast to intussusception in childhood, intussusception in adults usually has a definable lead point and resection of the involved bowel, rather than simple reduction, is indicated.

Major causes of intestinal obstruction in Libya.

The object of this study is to focus attention on the causes of intestinal obstruction in Libya. In this study, spread over 30 months and involving 114 patients, the most common cause was the entrapment of bowel in an external hernia. Postoperative adhesions accounted for obstruction in a third of our patients, and 59 per cent of them followed appendicectomy. Biliary lithiasis is the most common surgical disease in Libya, yet there was only one instance of gallstone ileus in this series. Sigmoid volvulus and intestinal lymphoma were also rare, and tubercular stricture and Crohn's disease were remarkable by their absence. There were no cases of idiopathic intussusception during or immediately following Ramadan.

Intussusception and intestinal malrotation in infants: Waugh's syndrome.

The position of the duodenojejunal flexure was determined in 37 out of a group of 49 consecutive infants presenting with intussusception. The flexure was in a normal position in 19, at the midline in 3, and in an abnormal position in 15. The caecum was unfixed in all of the 41 infants subjected to operation. It is concluded that lack of normal rotation and fixation of the intestine is an important factor in the aetiology of idiopathic intussusception of infants.

Adult intussusception in Glasgow 1968-74.

A further review of adult intussusception in Glasgow between 1968 and 1974 is presented. A higher than expected incidence of idiopathic intussusception has been found both in this and in the earlier Glasgow series of Smith and Gillespie (1968)--44 per cent and 50 per cent respectively.

Antibiotic‐Induced Mesenteric Adenopathy in an Intussusception Mouse Model: A Randomized, Controlled Trial

Idiopathic intussusception is a leading cause of intestinal obstruction in young children. Although the etiology remains obscure, lymphoid hyperplasia is found in a majority of cases. Antibiotics, the most frequently prescribed medication class in the pediatric population, have been recently associated with intussusception. The authors sought to determine whether enteral antibiotic exposure influences the development of mesenteric adenopathy, bowel dilation or intussusception in an animal model. The authors conducted a randomized, controlled animal trial using a previously described intussusception model. Mice were gavaged with normal saline, amoxicillin-clavulanate or azithromycin twice daily for 5 days to assess the influence of enteral antibiotic exposure on intussusception, mesenteric adenopathy and bowel dilation. One pediatric surgeon performed all laparotomies and was blinded to group designation. Chi2 and Fisher exact tests were used to evaluate differences between antibiotic exposed and control groups. Mesenteric adenopathy was identified in 4.1% of the normal saline controls compared with 54.1% (P < 0.01) and 38.9% (P < 0.01) of the amoxicillin-clavulanate and azithromycin exposed animals, respectively. A total of four intussusceptions were observed in the antibiotic-exposed groups combined whereas no intussusception cases were identified in the control group (P = 0.30). This is the first study to describe a significant association between antibiotic use and mesenteric adenopathy in any animal species.

Twenty-one cases of small bowel intussusception: the pathophysiology of idiopathic intussusception and the concept of benign small bowel intussusception.

Ultrasonography (US) was used to study intussusceptions prospectively at Kiyama Hospital in 1999 and 2000 under the classification of small bowel intussusception (SBI) and large bowel or ileo-ileo-colic intussusception (LBI). The clinical features, management, outcome and etiology were analyzed. All LBIs and SBIs with ischemic symptoms and SBIs complicated by LBI were treated by enema reduction, whereas SBIs considered to be nonischemic were observed. SBI was seen in 21 patients with a mean age of 62.6+/-31.2 months. Four cases (19.0%) were diagnosed during the course of LBI. US showed mesenteric lymphoid hyperplasia in 15 (71.4%). Hydrostatic enema reduction was successful in 9/9, and SBI reduced naturally in the other 12 (benign SBI). LBI occurred in 38 patients with a mean age of 27.8+/-21.2 months. Mesenteric lymphoid hyperplasia was observed in 29 (76.3%). Hydrostatic enema reduction was successful in 37/38. SBI occurs more frequently and in a wider age group than previously considered. Many SBIs reduced naturally, suggesting that they were only transient invagination phenomena and should be called benign SBI. The frequent association of SBI with LBI and also the frequent association of mesenteric lymphoid hyperplasia with both SBI and LBI seem the key to the pathophysiology of intussusception.

Infection and the gut

Gastrointestinal symptoms, including vomiting, are caused by a variety of infective organisms in children, many of which are self-limiting and resolve within a week, but ohers are potentially much more serious in their consequences. Diarrhea, vomiting and abdominal pain are common but nonspecific symptoms. Investigation is dictated by the likely causative organism, given the age and presentation of the child. The role of bacteria in the pathogenesis of necrotizing enterocolitis, recognition that Yersinia, Campylobacter and Salmonella may produce symptoms difficult to distinguish clinically from appendicitis, the viral causes of idiopathic intussusception, the occurrence of intussusception after administration of rotavirus vaccine, and the evidence incriminating mycobacterium avium subspecies paratuberculosis in the aetiology of Crohn disease are discussed.

Transient adult jejunal intussusception

Intussusception is a rare cause of abdominal pain in adults. It occurs in fewer than 1% of all cases of adult small bowel obstruction. In the adult population, most cases are the result of some type of intestinal lesion like adhesions, melanomas, lipomas or adenomatous polyps. Idiopathic intussusceptions are an extremely rare occurrence in adults, comprising only 2–23% of diagnosed intussusceptions. This report describes two cases of transient, idiopathic adult jejunal intussusception in a 19-year-old woman and a 39-year-old man, both presenting to the same hospital 1 week apart. Both patients complained of nonspecific abdominal pain and nausea and were diagnosed with intussusception by computed tomography (CT) scan. In both cases, no underlying bowel abnormality was identified and neither required a bowel resection. This report discusses the common presentation, diagnosis, and treatment of adult intussusception and questions whether patients with transient intussusceptions require exploratory laparotomy.

Idiopathic enteroenteric intussusceptions in adults.

Intestinal intussusception is infrequent in the adult, especially in the idiopathic and transitory forms. We reviewed the medical records and imaging of four patients with seven idiopathic and transitory intestinal intussusceptions discovered in the course of barium meal and small bowel follow-through radiologic studies carried out for nonspecific abdominal pain. The patients had nonobstructive intestinal intussusception, with no demonstrable underlying cause. Some intussusceptions were resolved by applying pressure to separate the pathologic intestinal loop. No complications associated with the intussusceptions were found during subsequent follow-up. There are cases of idiopathic nonobstructive intestinal intussusception in the adult, with few or no clinical repercussions that require aggressive medical intervention.

Association between antibiotic use and primary idiopathic intussusception.

Intussusception is the leading cause of intestinal obstruction in young children. Antibiotics are the most frequently prescribed medication in the pediatric population and have common adverse effects on the gastrointestinal tract. To determine whether a relationship exists between primary idiopathic intussusception and antibiotic drug use. Case-control study. Ninety-three case patients with intussusception and 353 injury controls younger than 4 years who were seen at the emergency department of the Children's Hospital of Alabama between January 1, 1996, and April 30, 2001, were included. Controls were matched to cases by quarter and year of time of diagnosis, age, and sex. Odds ratios and 2-sided 95% confidence intervals were estimated using conditional logistic regression. Prevalence of antibiotic use in an age-standardized, representative sample of US children from NHANES III (Third National Health and Nutrition Examination Survey) was used for external comparisons. Antibiotic use within 48 hours of diagnosis was found in 23 cases (25%) and 33 controls (9%) (odds ratio, 4.15; 95% confidence interval, 2.17-7.92; attributable risk, 18.7%). Antibiotic use among US children according to NHANES III was 10.7%. In cases, the beta-lactam class accounted for 78% of all medications used. Cephalosporin use was associated with more than a 20-fold increased risk of intussusception. An association between antibiotic drug use and intussusception was identified.

Florid Vascular Proliferation of the Colon Related to Intussusception and Mucosal Prolapse: Potential Diagnostic Confusion with Angiosarcoma

With the exception of angiodysplasia, vascular abnormalities of the intestines are unusual. We describe a florid benign vascular proliferation of the colon in five adult patients, three of whom presented with idiopathic intussusception. In all cases, the proliferation was sufficiently exuberant to raise the possibility of angiosarcoma as a diagnostic consideration. The group included 2 males and 3 females with a median age of 43 years. Two patients were HIV positive. Four patients presented with a colonic mass; other symptoms at presentation included abdominal pain, diarrhea, bleeding, and bowel obstruction. In all cases, a florid lobular proliferation of small vascular channels lined by plump endothelial cells extended from the submucosa through the entire thickness of the bowel wall. The endothelial cells showed minimal nuclear atypia, and mitotic figures were infrequent. The overlying mucosa showed ulceration with ischemic-type changes, and had features of mucosal prolapse. A possible underlying arteriovenous malformation was identified in two cases. All patients were alive and well at last follow-up (interval, 6 months to 5 years). The presence of intussusception or mucosal prolapse in all of the cases suggests repeated mechanical forces applied to the bowel wall as a possible etiologic factor. The role of HIV infection in the pathogenesis of these lesions remains to be determined.

Hydrostatic Reduction of Iatrogenic Intussusception of the Ureter Secondary to Percutaneous Nephrostomy Catheter Exchange

JVIR 2000; 11:1076–1078 ANTEGRADE intussusception of the ureter is a rare but well-recognized condition. The vast majority of cases have been associated with intraureteral polyps, although a recent case of idiopathic intussusception has been reported. All reported cases, regardless of etiology, have been managed surgically. We present the case of a 63-yearold man with bilateral hydronephrosis who developed a retrograde intussusception of his right ureter secondary to manipulation of a nephrostomy catheter during percutaneous catheter exchange. The intussusception was recognized at the time and was reduced completely with hydrostatic pressure. The patient was followed for 7 months with routine catheter exchange, until his death from unrelated causes. There was no evidence of recurrence during this time. This case is unique in its involvement of two unusual conditions: retrograde intussusception of the ureter secondary to antegrade catheter manipulation and successful reduction of this ureteric intussusception with hydrostatic pressure.

Rotavirus infection and intussusception: a view from retrospect.

A live orally-administrable rhesus rotavirus (RRV) tetravalent (TV) vaccine, licensed in the U.S.A. and the European Union, was recalled from the market because it was suspected to increase the risk of intussusception during the week following immunization. In contrast, natural rotavirus infection is generally believed not to cause intussusception. Because my experience contributed to the first paper that linked intussusception with rotavirus infection, I have re-examined our own data published 22 years ago and other studies on this issue. I also made a case study of adenovirus and intussusception as a paradigm to establish an etiological association of viral infection and intussusception. My hypothesis postulated in this review is that natural infection of susceptible (or predisposed) infants with some rotavirus strains, probably serotype G3 rotaviruses, will result in an appreciable fraction of idiopathic intussusception. Thus, the number of rotavirus-induced intussusception cases may change reflecting the relative frequency of G3 strains, which I believe was much higher in the 70s than during the last two decades. The epidemiological data indicate that the RRV-TV vaccine triggers intussusception at a rate significantly higher than the background incidence rate following the week of vaccination, particularly after the first dose. In contrast, the data do not suggest that the cumulative incidence among the vaccine recipients increases accordingly, implicating that the risk of intussusception attributable to the RRV-TV vaccine may be minimal.

AN ADULT INTUSSUSCEPTION DUE TO LIPOMA IN THE ILEUM WITH A 17-YEAR HISTORY-A CASE REPORT AND REVIEW OF THE LITERATURE-

A 61-year-old woman was admitted to the hospital because of a right lower abdominal tumor and pain lasting for about 17 years. Abdominal CT scan indicated an intussusception in the ascending colon, but the right lower abdominal tumor disappeared spontaneously. An idiopathic intussusception was suspected, because no possible causes could be determined by aggressive imaging studies. At laparotomy, intussusception due to a tumor in the ileum locating 50cm to the terminal ileum was detected, and the affected portion was resected. The resected specimen showed a submucosal tumor 2.5×2.5×2.5cm in size and several polyps of 4mm in size. Histopathologically they were benign lipoma and inflammatory polyps, respectively. We report this case with a review of a total of 153 cases of adult intussusception reported for a last one decade in Japan.

Unsuccessful air-enema reduction of intussusception: is a second attempt worthwhile?

Pneumatic reduction of idiopathic intussusception is successful in about 80% of cases, while 60% of the failures are reduced at surgery without resection. To determine whether delayed, repeated attempts at enema reduction of failures would reduce the need for operation in selected cases, over a 2-year period (1994-1996 inclusive), 17 infants with idiopathic intussusception underwent delayed repeat enemas 2-19 h following the first failed attempt at reduction. Clinical parameters and radiologic findings were evaluated with respect to outcome. Ten intussusceptions were successfully reduced after the second attempt in 9 and after the fourth attempt in 1. Seven children underwent a laparotomy, 5 because of failure of progressive reduction at air enema (AE). Two were taken to surgery early in the series, 1 because of perforation during a second attempt and 1 while awaiting a third reduction attempt. The 10 successful reductions all showed progressive movement of the intussusceptum on each AE; the 2 who perforated failed to show progressive reduction on their second AE. Because of these cases, the remaining 5 were referred to surgery because of failure of progressive reduction of the intussusceptum on the second attempt. At laparotomy, of the 7 unsuccessful reductions, 4 required resection and 3 had difficult manual reduction. The presence of vomiting, a mass, and/or bloody stools were not predictors of outcome. Failures had higher body temperatures (38.1 +/- 0.3 vs 37.4 +/- 0.1 degrees C, P = 0.07), heart rates (153.7 +/- 8 vs 136.9 +/- 2.1 min, P = 0.03), and longer duration of symptoms (36.8 +/- 4 vs 21.3 +/- 3.6 h; P = 0.01) than successes. Delayed repeat AEs may be safe and effective in selected cases of idiopathic intussusception, but should be considered only if significant movement of the intussusceptum is noted at each attempt. The ideal time for repeat AE reduction prior to surgery is not established, but 2-4 h appears appropriate. Pyrexia, tachycardia, and duration of symptoms greater than 36 h are relative contraindications to this course of management.

Familial idiopathic intussusception: A report of two families

The authors report on two families with 5 out of 10 and two of two siblings who presented with idiopathic ileocolic intussusception. This may suggest hereditary predisposition as an etiologic factor.
