Sonography of pediatric small-bowel intussusception: differentiating surgical from nonsurgical cases.

OBJECTIVE: The purpose of this study was to determine whether there are clinical or sonographic findings that can be used to differentiate benign self-limited small-bowel intussusception from pathologic small-bowel intussusception that necessitates surgical intervention. MATERIALS AND METHODS: A retrospective search was performed of abdominal sonograms obtained at two institutions between January 1996 and June 2005. Sonographic findings were correlated with medical and surgical records. RESULTS: A total of 35 cases of isolated small-bowel intussusception were found. Thirteen (37%) of these cases necessitated surgical intervention, and 22 (63%) of the cases were benign and self-limiting. Patients with self-limiting intussusception were younger than patients with intussusception necessitating surgical intervention (mean, 4.2 vs 7.5 years; p = 0.0327). Abdominal sonograms depicted ascites and small-bowel obstruction significantly more frequently in patients with small-bowel intussusception necessitating surgery (n = 7 [54%] for each finding) than in patients with self-limiting intussusception (n = 2 [9%], n = 0) (p = 0.006 and p = 0.0003, respectively). At sonography, patients who later underwent surgical intervention had small-bowel intussusception of significantly greater length (mean, 7.3 cm) than those treated conservatively (mean length, 1.9 cm) (p < 0.0001). Intussusception length greater than 3.5 cm was considered a sensitive and specific independent predictor of the need for surgery (sensitivity, 93%; specificity, 100%). CONCLUSION: When small-bowel intussusception is detected in infants and children undergoing abdominal sonography, intussusception length greater than 3.5 cm is a strong independent predictor of the need for surgical intervention.

Adult intussusception: a 12-year experience, with emphasis on etiology and analysis of risk factors.

BACKGROUND: To determine the incidence, causes, and associated risk factors of adult intussusception. METHODS: Forty-five cases of adult intussusception proven by surgery were collected from 58,000 surgeries performed from December 1986 through December 1998. The condition leading to intussusception, imaging studies, and clinical risk factors were analyzed. RESULTS: Nineteen men and 26 women, 18 to 83 years of age (mean, 52.6 years), experienced intussusception. The incidence of adult intussusception was 0.08% of abdominal surgeries and 3.0% of intestinal obstructions. A benign process was diagnosed in 25 cases (55.6%), malignancy in 16 cases (35.6%), surgery-related intussusception in 1 case (2.2%), and an idiopathic condition existed in 3 cases (6.6%). The major cause of adult intussusception due to benign lesions was polyps (12/25) and for malignancy, it was colonic adenocarcinoma (14/16). The diagnostic imaging rates were 52% for computed tomography, 41% for barium studies and 32% for abdominal ultrasound. There was no mortality due to intussusception; 4 patients (8.9%) died of colon cancer with liver metastasis. No definite risk factor was identified, but leukocytosis and a shorter preoperative duration tended to increase the risk of complications (p = 0.084, 0.082 respectively). CONCLUSION: Malignancy was the major cause of colonic intussusception, as was a benign process the primary cause of intestinal intussusception. These adult patients with intussusception received adequate surgical care and had a good prognosis except for those with colon cancer and liver metastasis.

Endotoxemia associated with intussusception and its diagnostic and surgical interventions.

To determine if and when intussusception results in endotoxemia and to evaluate whether diagnostic and surgical interventions of intussusception aggravate endotoxemia, intussusception was created in seven pigs during general anesthesia (ileocolic n = 3, ileo-ileocolic n = 2, ileocolic with silicone ring as leadpoint n = 1, ileoileal with silicone ring n = 1). After a period of observation and before progression to bowel gangrene, a diagnostic ultrasound study with a saline enema was undertaken, followed by a laparotomy and resection of the intussusception with a primary bowel anastomosis. Serial blood samples were obtained before and at regular intervals after: (1) formation of the intussusception; (2) the enema; and (3) resection for endotoxin measurement by limulus amebocyte lysate assay. The mean level of endotoxin increased from a pre-intussusception value of 0.750 EU/ml (range: 0.215-1.281) to a post-intussusception maximum of 1.482 EU/ml (0.997-2.882, P = 0.009), peaking mostly at 2 h after the intussusception. The mean pre-saline-enema level was 1.547 EU/ml (0.869-2.677) while the post-enema level was 1.41 EU/ml (0.84-2.468, P = 0.655). The mean pre-resection level was 1.470 EU/ml (0.784-2.468) while the post-resection maximum was (2.130 EU/ml) (0.850-4.381, P = 0.09). It is concluded that: (1) even in the absence of bowel gangrene intussusception results in significant endotoxemia within 2 h of its formation; (2) gentle saline enemas are not associated with endotoxemia; and (3) surgical resection results in a further upward surge of endotoxemia. These findings provide a scientific basis for improved understanding and management of intussusception.

AIDS-associated intussusception in young adults.

We have examined the changing demographics of adult intussusception and implicate human immunodeficiency virus (HIV)- and acquired immune deficiency syndrome (AIDS)-associated gastrointestinal pathology as risk factors for intussusception in young adults. The clinical index of suspicion for intussusception should be raised for an HIV-positive young adult with intermittent crampy abdominal pain. Over a 10-year period, eight cases of adult intussusception were diagnosed at our institution, and we reviewed the diagnostic computed tomography (CT) scans and records of these patients to correlate them with radiological studies, clinical history, surgical findings, laboratory studies, pathologic analysis, and outcome. Three of the eight patients with adult intussusception had AIDS, all diagnosed by CT scans. Their average age was 41 years, whereas average age of the non-HIV-associated patients was 63. These findings suggest that HIV- and AIDS-associated gastrointestinal pathology provide lead points for intussusception and are significant risk factors for intussusception in young adults. We reviewed the five previously reported cases of AIDS and intussusception and conclude that intussusception should be a diagnostic consideration in an HIV-positive young adult with abdominal complaints. It is clear that AIDS-associated intussusception is a real clinical problem and that CT is an effective method of diagnosing it.

Distinguishing features of self-limiting adult small-bowel intussusception identified at CT.

PURPOSE: To determine if clinical or computed tomographic (CT) findings can be used to distinguish self-limiting cases of adult small-bowel intussusception from those requiring surgery. MATERIALS AND METHODS: Thirty-seven cases of adult small-bowel intussusception were identified by a retrospective computerized search of 69,040 abdominopelvic CT examinations performed over a 4-year period. Two independent readers recorded CT features. Clinical findings and outcomes were determined by review of all available medical records. Outcome was classified as either surgical or self-limiting. Association between predictive variables and outcome was assessed by the Fisher exact test and logistic regression models. A multivariate, stepwise, logistic regression model was used to determine the best predictors of outcome. RESULTS: Six patients (16%) underwent surgery, and all had lead-point tumors. Thirty-one patients were cared for conservatively (84%) and none required surgery at a mean follow-up of 5.2 months (range, 0-46 months). Multivariate, stepwise, logistic regression analysis showed intussusception length was the only variable that was independently predictive of outcome. All 20 patients with an intussusception length of 3.5 cm or less, as measured by either reader, had cases that were self-limiting. Seventeen patients had an intussusception length greater than 3.5 cm, as measured by either reader. Eleven patients had an intussusception that was self-limiting, and six patients had an intussusception that required surgery. CONCLUSION: Intussusception length is the main factor in distinguishing the majority of small-bowel intussusceptions detected at CT that are self-limiting from the minority that require surgery. An intussusception that is shorter than 3.5 cm is likely to be self-limiting.

Ileoileocolic intussusception in children: diagnosis and significance.

The ileoileocolic type of childhood intussusception is difficult to diagnose pre-operatively and is associated with increased morbidity. This study describes the clinical and imaging features of 10 consecutive ileoileocolic intussusceptions diagnosed ultrasonically in 10 patients over a 36 month period. Ultrasound-guided hydrostatic reduction using Hartmann's solution was attempted in all 10 patients. Clinical and imaging features were compared with those of 28 ileocolic intussusceptions in 25 patients diagnosed and treated using the same methods during the same period. Most of the clinical and plain radiographic features of the patients with the ileoileocolic and ileocolic types of intussusception were similar. The two types of intussusception had the classical doughnut or pseudokidney, or both, signs on pre-reduction ultrasound scans. During the reduction process, when surrounded by fluid within the caecal lumen, the ileoileocolic type of intussusception had a typical complex appearance due to frond-like loops of intussuscepted small bowel. This finding was present in all cases. The hydrostatic reduction rate was only 10% (1/10) for ileoileocolic intussusception, compared with 92.9% (26/28) for the ileocolic type. All unsuccessfully-reduced cases underwent surgery, with surgical confirmation of the intussusception type in all cases. Only one patient was found to have a lead point, caused by a Meckel's diverticulum. In conclusion, the diagnosis of ileoileocolic intussusception can be made pre-operatively and these patients require surgical management.

Sonographic detection of lymph nodes in the intussusception of infants and young children: clinical evaluation and hydrostatic reduction.

OBJECTIVE: Our aim was to assess the sonographic appearance of enlarged lymph nodes in the intussusception in infants and young children and to investigate whether the enlarged lymph nodes affect the hydrostatic reduction rate of intussusception. MATERIALS AND METHODS: This retrospective case control study included a total of 65 children with intussusception, consisting of two groups: a study group of 28 patients with lymph nodes detected in intussusception and a reference group of 37 patients of similar age without lymph nodes in intussusception. The selection criterion for the study group was the presence of a minimum of two lymph nodes, of which at least one had a long axis of 11 mm or greater. The intussusception patterns, target or doughnut-like, and the presence of trapped fluid in the intussusception were also evaluated. Clinical records were reviewed for associated disease. The reducibility of both study and reference groups was assessed and correlated with all the sonographic features mentioned. RESULTS: Twenty-two of the 28 patients in the study group and none in the reference group had a recent or a current history of gastroenteritis. The overall hydrostatic reduction rate was 46.4% in patients with enlarged lymph nodes in the intussusception and 81.1% (p < 0.005) in patients without enlarged lymph nodes in the intussusception. Larger rather than numerous lymph nodes significantly affected the reducibility rate. Most of the reference group patients had a hydrostatic reduction at first attempt, whereas a second attempt at hydrostatic reduction was required in most of the study group patients. CONCLUSION: Enlarged lymph nodes in the intussusception are mainly found in patients with a current or recent history of gastroenteritis and decrease the overall hydrostatic reduction rate.

Intussusceptive angiogenesis: its role in embryonic vascular network formation.

Intussusceptive angiogenesis is a novel mode of blood vessel formation and remodeling, which occurs by internal division of the preexisting capillary plexus without sprouting. In this study, the process is demonstrated in developing chicken eye vasculature and in the chorioallantoic membrane by methylmethacrylate (Mercox) casting, transmission electron microscopy, and in vivo observation. In a first step of intussusceptive angiogenesis, the capillary plexus expands by insertion of numerous transcapillary tissue pillars, ie, by intussusceptive microvascular growth. In a subsequent step, a vascular tree arises from the primitive capillary plexus as a result of intussusceptive pillar formation and pillar fusions, a process we termed "intussusceptive arborization." On the basis of the morphological observations, a 4-step model for intussusceptive arborization is proposed, as follows: phase I, numerous circular pillars are formed in rows, thus demarcating future vessels; phase II, formation of narrow tissue septa by pillar reshaping and pillar fusions; phase III, delineation, segregation, growth, and extraction of the new vascular entity by merging of septa; and phase IV, formation of new branching generations by successively repeating the process, complemented by growth and maturation of all components. In contrast to sprouting, intussusceptive angiogenesis does not require intense local endothelial cell proliferation; it is implemented primarily by rearrangement and attenuation of the endothelial cell plates. In summary, transcapillary pillar formation, ie, intussusception, is a central and probably widespread process, which plays a role not only in capillary network growth and expansion (intussusceptive microvascular growth), but also in vascular plexus remodeling and tree formation (intussusceptive arborization).

Plain abdominal radiography in suspected intussusception: a reassessment.

The objectives of the study were (1) to determine the interobserver variation in interpretation of abdominal radiographs in children with clinically suspected intussusception, and (2) to determine the diagnostic value of abdominal radiographs in these patients. One hundred and eighty-two plain abdominal radiographic examinations (AXR) performed in children with clinically suspected intussusception were reviewed blind to the clinical history and findings of air enema. The presence or absence of nine AXR signs relevant to intussusception was documented. Each AXR was categorized as equivocal, positive or negative for intussusception, with the aim of achieving no false negatives. Interobserver variation in the identification of AXR signs and radiologic diagnoses was calculated using the kappa statistic for 60 cases assessed independently by three observers. Using the findings of air enema as gold standard, the prevalence of AXR signs in all patients with (60) and without (122) intussusception was determined and their diagnostic values calculated. The best observer agreement was for the presence of sparse small bowel gas (supine, k = 0.68) and the worst for the presence of cecal gas (erect, k = 0.18). All three observers agreed intussusception to be present or absent in only 7 of 60 cases and the majority agreement was equivocal in more than half. Overall agreement between observers for the diagnosis of intussusception was k = 0.30. The best positive predictors of intussusception were the soft tissue mass and sparse large bowel gas, with likelihood ratios of 3.9 and 2.5. Cecal feces predicted against intussusception, likelihood ratio 0.11. AXR was equivocal in 53%, positive in 21% and negative in 26%. Where a firm radiographic diagnosis was made, the diagnostic accuracy of AXR was 84%.(ABSTRACT TRUNCATED AT 250 WORDS)

The effect of screening sonography on the positive rate of enemas for intussusception.

BACKGROUND: The referring physicians at our institution used the enema as a diagnostic test in children with suspected intussusception. OBJECTIVE: To determine the change in rate of positive enema findings performed for suspected intussusception with the intervention of screening ultrasound (US). MATERIALS AND METHODS: Since October 1995, 224 children (mean age 2.2 years) with suspected intussusception were referred for enema examination. In January 2001, US was introduced as a screening test for intussusception. Enemas were performed for all children with positive US findings and were offered for those with negative US findings if clinical suspicion persisted. RESULTS: Before 2001, 184 children underwent enema with intussusception documented in 40 (22%). Since January 2001, 40 children have been seen with suspected intussusception (12/40 positive or 30%). Two directly underwent enema (1/2 positive); 38 children underwent US. In 12 of 38 children, the US finding was positive, and an intussusception was found at enema examination in 11 of 12. In 26 cases, the US finding was negative. Seven of the 26 children with a negative sonogram finding had an enema, which was also negative. Nineteen enemas were canceled. With a screening US, the positive rate for enemas is now 58% (11/19). We know of no case of intussusception missed at US. CONCLUSION: Screening US has decreased unnecessary enemas for clinically suspected intussusception, increasing positive findings from 22% to 58%. This has in turn reduced children's exposure to radiation.

Transient small-bowel intussusception in children on CT.

OBJECTIVE: To determine the frequency and significance of small-bowel intussusception identified in children on CT. MATERIALS AND METHODS: All abdomen CT reports between July 1995 and April 2002 were reviewed to identify patients with small-bowel intussusception. Intussusceptions were identified as an intraluminal mass with a characteristic layered appearance and/or continuity with adjacent mesenteric fat. Ileocolic intussusceptions and intussusceptions related to feeding tubes were excluded. Imaging studies and medical records were reviewed. RESULTS: Twenty-five pediatric patients (16 boys, 9 girls; mean age 11.2 years) were identified with small-bowel intussusception on CT. No patient had a persistent intussusception requiring surgery. Fourteen had limited immediate repeat CT images as part of the same examination, ten of which demonstrated resolution of the CT abnormality. Follow-up CT [ n=13 (6 within 24 h)], ultrasound ( n=3), small-bowel follow-through ( n=4) and surgery ( n=3) showed no intussusception. In four patients with persistent symptoms, underlying pathology was identified requiring treatment (giardiasis, 2; small-bowel inflammation/strictures, 1; abscess and partial small-bowel obstruction after perforated appendicitis, 1). In 21 other patients, direct correlation of symptoms to CT abnormality was absent or questionable, no treatment was required, and there was no clinical or imaging evidence of persistence or recurrence. CONCLUSION: Most small-bowel intussusceptions identified in children by CT are transient and of no clinical significance.

Spontaneous reduction of intussusception: clinical spectrum, management and outcome.

BACKGROUND: To analyze the spectrum of clinical features, management and outcome of children with documented spontaneous reduction of intussusception (SROI). MATERIALS AND METHODS: Review of records of 50 children (33 boys, 17 girls; age range 11 days-15 years; mean age 4 years) with documented SROI, in whom intussusception was initially diagnosed by sonography (US) in 44, air enema in 2, and computed tomography in 4, in the 6-year period 1992-1998. RESULTS: Symptoms suggestive of intussusception were present in 21 (3 of whom had Henoch-Schönlein purpura and 4 had previous ileocolic intussusception reduced by air enema). Intussusception was an incidental finding in the other 29, in 28 of whom the finding was in the small bowel. Intussusception was limited to the small bowel in 43 and was ileocolic in 7. SROI was usually documented on US. Laparotomy performed in only 4 showed no evidence of intussusception or pathologic lead point. Outcome in all patients was favorable. CONCLUSIONS: SROI may present in symptomatic or asymptomatic children and occurs more commonly than previously reported. These intussusceptions are usually short-segment, small-bowel intussusceptions with no recognizable lead point. In asymptomatic patients, conservative observation is warranted. Intervention should be dictated by the clinical findings in symptomatic patients.

Sonographic features indicative of hydrostatic reducibility of intestinal intussusception in infancy and early childhood.

The aim of the study was to investigate the various sonographic patterns of intussusception, which may be indicative of its reducibility by hydrostatic reduction. Seventy-one infants and children clinically suspected of having intussusception were studied sonographically and given barium enemas. Sonographic patterns of intussusception were correlated with its reducibility. When the head of intussusception appeared as a target-like mass the hydrostatic reduction rate was 100%. When demonstrated as a doughnut-like mass, the intussusception reducibility depended on the thickness of the hypoechoic external ring of the "doughnut". With a thickness equal to, or less than, 7.2 mm the reduction rate was 100%, with a thickness ranged between 7.5 and 11.2 mm the reduction rate was 68.9% and with a thickness measured 14 to 14.2 mm a surgical resection of bowel was required. When a small amount of fluid appeared within the head of intussusception, like a crescent hypoechoic area, the hydrostatic reduction was unsuccessful, regardless of the sonographic pattern of intussusception (target- or doughnut-like mass). The presence of a small amount of free peritoneal fluid did not affect the reducibility of intussusception. In conclusion, sonographic patterns of intussusception identify good and poor prognostic features for the success of hydrostatic reduction.

Clinical spectrum and surgical approach of adult intussusceptions: a multicentric study.

BACKGROUND: The preoperative diagnosis of adult intussusceptions (AIs) remains difficult, and the assessment of the radiological methods has been evaluated very little in the literature. The aim of this study was to evaluate the interest of the different imaging modalities for the preoperative diagnosis of AI and describe causes of AI. PATIENTS AND METHODS: Consecutive patients of 15 years and older with the postoperative diagnosis of intussusception from 1979 to 2004 were reviewed retrospectively for this multicentric study. Data concerning clinical considerations, morphological examinations, surgical procedure, histological conclusions, mortality rate and recurrence were analysed. RESULTS: Forty-four patients with documented intussusception were included. The mean age was 51 years (15-93 years). The preoperative diagnosis of intussusception was made in 52% of the cases. The sensitivities of the different radiological methods were abdominal ultrasounds (35%), upper gastrointestinal barium study (33%), abdominal computed tomography (CT) (58%) and barium enema (73%). An organic lesion was identified in 95% of the cases. There was 29 enteric and 15 colonic (including appendicular) intussusceptions. Thirty-seven percent of the enteric lesions were malignant, and a bit less than 50% of them were metastatic melanomas. The benign enteric lesions were Meckel's diverticulum and Peutz-Jeghers syndrome in half of the cases. Fifty-eight percent of the pure colonic lesions (excluding appendix) were malignant, and 85% of them were primary adenocarcinomas. The benign colonic lesions were lipomas in 80% of the cases. All patients, except one, had a surgical treatment, and 13 of them had a complete reduction of the intussusception before resection. The mortality rate was 16% and recurrence occurred in three patients; two of them had a Peutz-Jeghers syndrome. CONCLUSION: Intussusception rarely occurs in adults, but nearly half of their causes are malignant. The CT scan is a helpful examination for enteric intussusceptions whether barium enema seems to be the most performing method for colonic lesions. Surgery is the recommended treatment, with or without a primary reduction of the intussusception. During the surgical procedure, this reduction can lead to a more limited bowel resection.

Conservative treatment for small intestinal intussusception associated with Henoch-Schönlein's purpura.

PURPOSE: Emergency laparotomy is generally considered the appropriate course of action for small bowel intussusception associated with Henoch-Schönlein's purpura (HSP). In this paper, we define a conservative approach after witnessing spontaneous reduction of ileoileal invagination at laparotomy in a patient with HSP who had been on steroid therapy for renal involvement. METHODS: HSP was diagnosed by the appearance of a purpuric rash without thrombocytopenia. Intussusception was diagnosed by ultrasonography (USG) and plain abdominographs, which showed signs of obstruction, and clinical examination. Barium enema was used to treat ileocolic intussusceptions, and conservative therapy, consisting of nasogastric drainage, steroids, and intravenous fluid administration, was used to treat ileoileal intussusceptions. Emergency laparotomy was performed for the patients unresponsive to therapy within 24 h, those with peritonitis, and those with ileocolic invagination not able to be reduced by barium enema. RESULTS: Six children with an ileoileal intussusception and one with an ileocecal intussusception were studied. The average age was 6 years old. Apart from the initial patient in whom spontaneous reduction was seen at laparotomy, three others required emergency laparotomy; for ileocolic intussusception unable to be reduced by barium enema in one, for ileoileal invagination with peritonitis on admission in one, and for ileoileal intussusception unresponsive to conservative therapy in one. The other three patients were successfully treated by conservative therapy. CONCLUSION: Conservative therapy is feasible for HSP patients with small bowel intussusception as long as the time of onset is known, an ultrasonographic and X-ray diagnosis is confirmed, emergency operating facilities are available, and an experienced pediatric surgical team follows up the patients.

Rectal intussusception: characterization of symptomatology.

PURPOSE: Rectal intussusception is a common finding at evacuation proctography; however, its significance has been debated. This study was designed to characterize clinically and physiologically a large group of patients with rectal intussusception and test the hypothesis that certain symptoms are predictive of this finding on evacuation proctography. METHODS: A total of 896 patients underwent evacuation proctography from which three groups were identified: those with isolated rectal intussusception (n = 125), those with isolated rectocele (n = 100), and those with both abnormalities (n = 152). Multivariate analyses were used to identify symptoms predictive of findings by evacuation proctography. RESULTS: The symptoms of anorectal pain and prolapse were highly predictive of the finding of isolated intussusception over rectocele (odds ratio, 3.6, P = 0.006; odds ratio, 4.9, P < 0.001) or combined intussusception and rectocele (odds ratio, 2.9, P = 0.02; odds ratio, 2.4, P = 0.03). The symptom of "toilet revisiting" was associated with the finding of rectoanal intussusception (odds ratio, 3.55, P = 0.04). Although patients with mechanically obstructing intussuscepta evacuated slower and less completely (P < 0.001) than those with nonobstructing intussuscepta, no symptom was predictive of this finding on evacuation proctography. CONCLUSIONS: Although certain symptoms are predictive of the finding of rectal intussusception, there is a wide overlap with symptoms of rectocele, another common cause of evacuatory dysfunction. Furthermore, the observation that "obstruction to evacuation" made on proctography had no impact on the incidence of evacuatory symptoms suggests that beyond simply demonstrating the presence of an intussusception, analysis of proctography and subclassifying intussusception morphology seems of little clinical significance, and selection for surgical intervention on the basis of proctographic findings may be illogical.

Recurrent intussusception in children.

Twenty-eight children with 35 recurrent intussusceptions were collected and analyzed from a series of 600 intussusceptions over 17 yr. The overall recurrence rate in the entire series was 5% with 11% recurring after hydrostatic barium enema reduction, and 3% after operative reduction. Twenty-three children had one recurrence each, four children had two recurrences, and one child had four recurrent intussusceptions. More than two-thirds of the patients had a recurrence within 6 mo of their first intussusception, and half of these presented earlier and with fewer signs and symptoms than the previous attack had manifested. Twenty-one of 30 recurrences were reduced with barium enema. Sixteen were operated on, reducing nine manually and resecting four others. Only two leading points were found, and in both instances resection was required. All but two of the intussusceptions were ileocolic. The previous mode of reduction of each intussusception did not set a trend for future treatment of recurrent intussusceptions in the same child. While operative reduction diminishes the chances of a recurrent intussusception and ileocolic resection eliminates it, there does not seem to be any indication for surgery as long as barium enema reduction is successful. We have never observed the hydrostatic reduction of an intussusception caused by a leading point.

The etiologic role of intrauterine volvulus and intussusception in jejunoileal atresia.

PURPOSE: Although intussusception has been reported as quite a rare cause of jejunoileal atresia (JIA), pediatric surgeons have noted the frequent presence of intussusception as well as volvulus at surgery. The aim of this study was to investigate the contribution of intrauterine intussusception and volvulus to the development of JIA. METHODS: In 48 newborns (24 boys and 24 girls) treated for JIA at our hospital between 1978 and 2004, the operative and pathologic findings were reviewed. RESULTS: Intussusception was responsible for gap and cord type atresia in 12 cases (25%). The cord showed an atrophic intestinal lumen in 2 cases. Volvulus was observed in 13 cases. Volvulus and intussusception were simultaneously noted in 1 case. This suggested that intussusception was the cause of the atresia, whereas volvulus was a secondary event. Neither intussusception nor volvulus was observed in high jejunal, apple peel, or multiple atresia. CONCLUSIONS: Intrauterine volvulus and intussusception were commonly observed in single mid- and low JIA. Thus, intrauterine intussusception may be a common cause of gap and cord type JIA. Volvulus may not only cause JIA but also result from anatomic changes after the development of JIA in some cases.
