Perfil epidemiológico y clínico de la invaginación intestinal en lactantes de la Región Metropolitana

Background. Intussusception (IS) is a potentially severe disease that affects an undetermined number of Chilean infants. The withdrawal of a rotavirus vaccine in 1999 due to its association with IS, highlighted the need for updated information on IS worldwide including Chile, before introduction of...

Intussusception (IS) is a potentially severe disease that affects an undetermined number of Chilean infants. The withdrawal of a rotavirus vaccine in 1999 due to its association with IS, highlighted the need for updated information on IS worldwide including Chile, before introduction of new vaccines. Aim: To estimate the incidence and to describe the epidemiology and clinical presentation of IS in the Metropolitan Area of Chile. Material and methods. IS cases occurring between 1996 and 2001 in the seven public pediatric hospitals and in six private clinics (during 2000 and 2001) were identified. Incidence rates were calculated using updated population estimates. A systematic review of the medical charts of IS cases occurring in the public hospitals for 2000-2001 was performed. Results. IS incidence rates for the Public Sector ranged from 32 to 39 per 100.000 children < 2 years of age. These figures did not vary significantly among the different Health Care Services, nor after inclusion of the private clinics. IS was more common in males (66%) and infants younger than 12 months (83%), with 67% of cases occurring between 3 and 8 months of age. The most common presenting symptoms were abdominal pain (90%), vomiting (86%), and rectal bleeding (75%). Ileocolic IS predominated (83%) and surgical correction was the preferred treatment (81%). No death occurred in this series. Conclusions: IS incidence rates were intermediate compared to other series, stable over time, and similar between the public and private sector. Clinical characteristics were similar to those previously reported with a disproportionately high use of surgical correction over enema, currently considered the preferred treatment option.
