Pitfalls in the diagnosis of intussusception

Unusual sonographic behavior of intussusception is demonstrated in 4 cases. The results of 54 well-documented cases have shown two possible deviations from the normal sonographic pattern of an intussusception. The first was a highly reflective target sign, and the second a loss of regular sonographic structure in a tumor-like mass.     

Sonography of appendiceal intussusception

A case in which appendiceal intussusception was diagnosed preoperatively by sonography is described. The sonographic finding of multiple concentric hypoechoic and hyperechoic rings was confirmed at laparotomy to be due to appendiceal intussusception. Demonstration of the sonographic coiled spring sign in the right lower quadrant should raise the possibility of appendiceal intussusception. The differential diagnosis is discussed.     

高频彩超对小儿肠套叠的诊断价值

目的 探讨高频彩超对小儿肠套叠的诊断价值.方法 回顾性分析57例肠套叠患儿高频彩超的声像表现,总结其特征.结果 小儿肠套叠有其典型的声像图特征,其横断面表现为"同心圆"征,纵切面表现为"套筒"征.在肠壁严重水肿、阻力指数(RI)显著升高、无血流显示等情况时应尽快手术复位.57例患儿中52例经空气灌肠复位,3例手术和2例保守治疗患儿均治愈.结论 高频彩超可作为小儿肠套叠的首选检查方法.     

Sonographic diagnosis of juvenile polyps in children

The aim of this study was to assess the diagnostic value of ultrasonography for juvenile polyps in children and their sonographic characteristics. A retrospective analysis was performed of the ultrasound findings in 27 children who were diagnosed preoperatively with juvenile polyp within the intestinal tract by ultrasonography and then confirmed by colonoscopy, laparotomy and histopathology. The ultrasonic finding common to all polyps was an isolated intraluminal nodular or massive protrusion, associated with multiple mesh-like fluid areas of different sizes. In 25 children, surrounding pedicle-like low echoes of varying lengths were seen connecting with the polyps to form “mushroom” sign. The color Doppler showed abundant blood flow signals within all polyps and pedicles in a shape of a branch or an umbrella. For seven children with an intussusception, the polyp shadow was detected in the cervical part or interior of the intussusception. Ultrasonography is, thus, considered to be a feasible method for diagnosing intestinal juvenile polyp.     

Intussusception due to intestinal anisakiasis: Report of a case

This report describes our experience of intussusception due to intestinal anisakiasis which was treated by laparoscopy-assisted surgery. The unique sonographic findings of this complication were a pseudokidney sign and a target sign with an edema of Kerckrings folds in the intussusceptum. Surgeons should know about intussusception as a rare complication of intestinal anisakiasis. Sonography, computed tomography and laparoscopy are helpful in diagnosing and treating this complication.     

Tetra-layered sign of adult intussusception (new ultrasound approach)

Two-dimensional ultrasound is the principle method for the detection of intussusception. The aim of this study was to establish a pathognominic ultrasound criterion for diagnosing intestinal intussusception to facilitate a proper clinical decision. We have developed a new approach to diagnosing colonic intussuception based on the hypothesis that ultrasound image of the invaginated segment should reveal four border layers. We called this sign tetra-layered sign (TLS). In a prospective manner, all adult patients diagnosed with intussusception using the TLS approach in the period from July 1990 and July 2005 were included in this study. All patients underwent explorative laparotomy, and our preoperative diagnoses were compared with the surgical outcome. Thirty patients were diagnosed with intestinal intussusception using the TLS ultrasound sign. Surgery confirmed the preoperative diagnosis in all cases. Conventional ultrasound is very reliable in diagnosing intestinal intussusception in adult patients when utilizing the simple ultrasound applicable TLS. This facilitates the decision-making, improves the clinical outcome and reduces the associated costs.
