Intussusception is a serious disorder in which part of the intestine slides into an adjacent part of the intestine. This "telescoping" often blocks food or fluid from passing through. Intussusception also cuts off the blood supply to the part of the intestine that's affected. Intussusception can lead to a tear in the bowel (perforation), infection and death of bowel tissue. Intussusception is the most common cause of intestinal obstruction in children younger than 3.
tatistical analyses were performed with SPSS 13.0.0(SPSS Inc, Chicago, IL). Data on the general populationduring the study period were obtained from the SwissFederal Ofﬁce of Statistics. 26 Independent proportionswere compared by using the Pearson 2 test. P values of .05 were considered signiﬁcant.Reported cases were categorized into levels of diag-nostic certainty, with the Brighton Collaboration casedeﬁnition for acute intussusception, independently by 2of us (Drs Buettcher and Baer), followed by calculationof interobserver agreement as described previ-ously. 27 The capture-recapture analysis was performedaccording to the Chapman-Wittes adjustment of the Lin-coln-Petersen maximal likelihood estimate
An enema is the first step in treatment. In fact, an enema that is used to diagnose intussusception may also help to treat it. Pressure from the air or fluid may cause the intestine to correct itself. The result of an enema treatment might not last, so patients usually stay in the hospital overnight for observation. Surgery is another treatment option. Intussusception surgery involves either a large incision or a small incision and a camera. This is called laparoscopic surgery. The type of surgery depends on the location and severity of the obstruction. Intussusception surgery may include removal of the affected section of intestine. There were 294 patients with reported intussusception; 35 cases were excluded for various reasons, and 29 additional patients were identified through International Classification of Diseases. After capture-recapture analysis, we estimated underreporting to the Swiss Pediatric Surveillance Unit to be 32% and we calculated a true number of 381 intussusception episodes. The highest level of diagnostic certainty was reached by 248 patients, and 20 fulfilled level 2 criteria; for the remaining 20 patients. The mean age of the patients was 2.7 years. The yearly mean incidence of intussusception was 38, 31, and 26 cases per 100000 live births in the first, second, and third year of life, respectively, with no apparent seasonality. Seventy patients had a history of coinciding gastroenteritis, and 5 of 61 tested positive for rotavirus. Spontaneous devagination was observed for 38 patients; enemas reduced intussusception successfully in 183 cases, whereas surgical treatment was required in 67. All patients recovered without squeal.
