“…Given this increased detection of intussusception, even in asymptomatic patients, and given the recognition that some may be transient, there is an ongoing controversy regarding the optimal management of these cases. The general consensus is that proximal small-bowel intussusceptions measuring less than 3.5 cm in length and without obstruction or an obvious lead point are likely to be selflimiting and of no clinical significance [30], and larger sections should be monitored conservatively [31], only resorting to surgery if complications arise.…”

SummaryBackground Adult intussusception (AI) is a rare condition, usually with a lead point, and for which surgery is the treatment of choice. Given the risks and possible complications of untreated AI, an accurate preoperative diagnosis is of the utmost importance. Although AI remains difficult to diagnose, computerized tomography (CT) is presently considered the best diagnostic tool.Methods Sixteen patients of 20 years and older with intraoperative diagnosis of intussusception, who underwent surgery between January 2000 and December 2009, were reviewed retrospectively. Patients were assessed concerning clinical presentation, imagiological findings, surgical treatment, and postoperative histological evaluation.Results Most patients (93.8 %) were admitted via emergency room (ER) due to abdominal pain. Fourteen (87.5 %) AI cases showed an underlying organic cause, e.g., masses or tumors. The most frequent comorbidities were Peutz-Jeghers syndrome (PJS; 18.8 %) and HIV (12.5 %). Eight (50.0 %) intussusceptions were ileocolic and six (37.5 %) were in the small bowel. Total 43.8 % of lesions were malignant. Preoperative diagnosis of intussusception was possible in 50.0 % of cases by ultrasonography (US) and in 81.8 % by CT. US showed no predictive value concerning intussusception location. Total 27.3 % of CTs correctly identified the location, but only 9 % accurately identified the lead point.Conclusions We propose that all AI cases should be treated with surgical resection without attempting reduction, even when no lead point is detected by imaging studies, and this approach should be based on the oncological criteria. CT can be regarded as the most accurate diagnostic tool for intussusception, although its predictive value concerning location and lead point is still far from ideal.

“…Incidental intussusception was defined as intussusception detected on CT in patients with no symptoms attributable to the intussusception. 16 They are often transient and asymptomatic and usually do not appear on subsequent imaging. 17 Idiopathic (primary) intussusception was defined as an intussusception for which no etiology or lead point could be identified by imaging, exploration, and/or pathologic evaluation regardless of symptoms.…”

“…Dysrhythmic peristaltic activity has been proposed as the cause of intussusception in horses and people. Asymptomatic small bowel intussusceptions occur in humans and dogs and can resolve spontaneously (up to 20% in people and 8% in dogs), suggesting that this process might be underreported . Sonographic signs that have been associated with transient, nonclinical small intestinal intussusceptions are the absence of identifiable intestinal lesions, normal wall thickness, length of less than 3.5 cm, normal undilated proximal bowel, normal vascularity on color Doppler, respected layering, and the intussusception being compressible .…”

“…The authors had different levels of experience, ranging from 6 months to 30 years of ultrasound experience. Intussusceptions were identified in cross‐section if intestine with a classically described target‐like or doughnut appearance was observed, and in longitudinal section when the classically described sandwich sign was observed . One of the authors (MA) measured wall thickness of the intussusceptum and the intussuscipiens for each foal.…”

BackgroundUltrasonographic appearance of the gastrointestinal (GI) tract of equine neonates has not been completely described.ObjectivesTo describe (1) sonographic characteristics of the GI segments in normal nonsedated equine neonates, (2) intra‐ and interobserver variation in wall thickness, and (3) the sonographic appearance of asymptomatic intussusceptions, and (4) to compare age and sonographic findings of foals with and without asymptomatic intussusceptions.AnimalsEighteen healthy Standardbred foals ≤5 days of age.MethodsProspective, cross‐sectional blinded study. Gastrointestinal sonograms were performed stall‐side. Intraobserver variability in wall thickness measurements was determined by calculating the coefficient of variation (CV). The Bland–Altman method was used to assess interobserver bias. Student's t‐test and Fisher's exact test were used to test the association among presence of intussusceptions, age, and selected sonographic findings.ResultsThe reference ranges (95% predictive interval) for wall thickness were 1.6–3.6 mm for the stomach, 1.9–3.2 mm for the duodenum, 1.9–3.1 mm for the jejunum, 1.3–2.2 mm for the colon, and 0.8–2.7 mm for the cecum. Intraobserver wall thickness CV ranged from 8 to 21% for the 2 observers for 5 gastrointestinal segments. The interobserver bias for wall thickness measurements was not significant except for the stomach (0.14 mm, P < .05) and duodenum (0.29 mm, P < .05). Diagnostic images of mural blood flow could not be obtained. Asymptomatic intussusceptions were found in 10/18 neonates. Associations between sonographic variables or age and the presence of intussusceptions were not found.Conclusions and Clinical ImportanceSonographic characteristics of the GI tract of normal Standardbred neonates can be useful in evaluating ill foals. Asymptomatic small intestinal intussusceptions occur in normal Standardbred neonates.
