    Following the identification of medical tourism as a growth sector by the Malaysian government in 1998, significant government sector and private-sector investments have been channeled into its development over the past 15 years. This is unfolding within the broader context of social services being devolved to for-profit enterprises and 'market-capable' segments of society becoming sites of intensive entrepreneurial investment by both the private sector and the state. Yet, the opacity and paucity of available medical tourism statistics severely limits the extent to which medical tourism's impacts can be reliably assessed, forcing us to consider the real effects that the resulting speculation itself has produced and to reevaluate how the real and potential impacts of medical tourism are - and should be - conceptualized, calculated, distributed, and compensated for. Contemporary debate over the current and potential benefits and adverse effects of medical tourism for destination societies is hamstrung by the scant empirical data currently publicly available. Steps are proposed for overcoming these challenges in order to allow for improved identification, planning, and development of resources appropriate to the needs, demands, and interests of not only medical tourists and big business but also local populations.

    INTRODUCTION: Foreign body (FB) ingestion is a common paediatric emergency. While guidelines exist for urgent intervention, less is known of the natural progress of FBs passing through the gastrointestinal tract (GIT). We reviewed these FB transit times in an outpatient cohort.

    METHODS: A retrospective review was performed on all children (≤18 years) treated for radiopaque FB ingestion at two major tertiary paediatric centres from 2015 to 2016. Demographic data, FB types, outcomes and hospital visits (emergency department [ED] and outpatient) were recorded. All cases discharged from the ED with outpatient follow-up were included. We excluded those who were not given follow-up appointments and those admitted to inpatient wards. We categorised the outcomes into confirmed passage (ascertained via abdominal X-ray or reported direct stool visualisation by patients/caregivers) and assumed passage (if patients did not attend follow-up appointments).

    RESULTS: Of the 2,122 ED visits for FB ingestion, 350 patients who were given outpatient follow-up appointments were reviewed (median age 4.35 years [range: 0.5-14.7], 196 [56%] male). The largest proportion (16%) was aged 1-2 years. Coins were the most common ingested FB, followed by toys. High-risk FB (magnets or batteries) formed 9% of cases ( n =33). The 50 th centile for FB retention was 8, 4 and 7 days for coins, batteries and other radiopaque FBs, respectively; all confirmed passages occurred at 37, 7 and 23 days, respectively. Overall, 197 (68%) patients defaulted on their last given follow-up.

    CONCLUSION: This study provides insight into the transit times of FB ingested by children, which helps medical professionals to decide on the optimal time for follow-up visits and provide appropriate counsel to caregivers.
