This study aimed to document the baseline incidence and epidemiology of intussusception (IS) in Malaysia. This retrospective surveillance examined hospital discharge data from three hospitals in Malaysia to identify IS cases over a 3-year period (2000-2003) in children <5 years of age. Identification of definite cases of IS was done through a search of computerized hospital discharge records (ICD-9-CM code 560.0) followed by confirmation of diagnosis through medical record review. The definition of IS was based on the clinical guidelines from the IS Brighton Collaboration Working Group, version 2002. During the 3-year study period, there were 62 cases hospitalized due to IS, of which 74.2% were < 1 year of age. The incidences for hospitalization due to IS in children < 1 year old and < 5 years old averaged 17.8 and 4.8 per 100,000 person-years, respectively. No IS-associated deaths were recorded and all IS cases had a favorable outcome. No distinct seasonality with IS occurrence was observed.

The primary objective of this epidemiological surveillance study was to estimate the incidence of intussusception (IS) associated with hospitalisation in children <1, <2 and <17 years of age in Germany. We analysed primary and secondary ICD-10 discharge diagnoses for IS (K56.1) and procedure codes for desinvagination from 28 paediatric hospitals in Bavaria, Germany, to identify children hospitalised in 2005 or 2006 due to IS. A total of 518 children with an ICD-10 code for IS were reported: 123 (23.7%) of the children were <1 year of age, 267 (51.5%) were 1-3 years old and 128 (24.8%) older than 3 years of age. IS was the primary ICD-10 diagnosis in 382 (74%) children, including 231 (60%) children with a procedure code for desinvagination. In 136 (26%) children, IS was reported as a secondary ICD-10 diagnosis, including 38 (28%) with a desinvagination procedure code. The yearly incidence of IS in children <1 year of age was estimated as 72/100,000 overall and as 43/100,000 for those with an additional procedural code for desinvagination. Patients solely with an ICD-10 code for IS are often suspected cases, based on clinical presentation. The combination of the ICD-10 code for IS and a procedure code for desinvagination provides a more specific and clinically relevant case definition, thereby offering a useful tool for long-term surveillance of the incidence of IS.

Background: The aim of this study was to determine the baseline statistics of intussusception in the under-five- year age group in Iran to facilitate the monitoring of potential side effects after administration of rotavirus vaccine. Methods: This hospital-based historical cohort study reviewed children under 60 months of age with the final diagnosis of intussusception, ICD-10 code K56.1, using census in all hospitals of Tehran, Iran from March 2010-2015. Demographic (sex, age, hospital stay duration), clinical manifestations (such as currant jelly stool, abdominal pain, vomiting, and fever),diagnostic and treatment methods (contrast enema, ultrasonography, laparotomy, and laparoscopy), and outcome data of patients aged less than 5 years with the diagnosis of intussusception were collected and analyzed using SPSS Version 16.0 (SPSS Inc., Chicago, IL, USA) Results: In this study, 759 patients were diagnosed with intussusception; 309 (40.7%) cases were less than 12 months old. The annual incidence of intussusception was 66.54 cases per 100.000 in children less than one-year-old and 31.61 cases per 100.000 in children less than five years old. The most common symptoms and signs were abdominal pain/irritability (94.2%) and tenderness (24.2%), respectively. The diagnostic method was ultrasound in 75.9% of cases. The most frequent anatomic location was the ileocolic region (87.87%) and the most common treatment method was barium enema. Conclusion: This research has provided a baseline statistic for childhood intussusception in Tehran prior to the administration of the rotavirus vaccine to provide a better comparison with post-introduction data.
