Body packers: the ins and outs of imaging

Smuggling of drugs by body packing: Evidence from Chinese sentencing documents

BACKGROUND

In China, body packing as a means of transporting drugs was firstly found in Yunnan province in an area that shares a border with the Golden Triangle in late 1970s. Since then, drug trafficking cases that utilize body packing as the primary mode of transportation have increased substantially. Due to a scarcity of data, however, the scope and nature of such criminal activity is not thoroughly understood. This study provides a new approach to the analysis of body packing by digitizing and analyzing court sentencing documents in China from 2006-2016.

METHODOLOGY

This study implements network analysis and descriptive statistics to identify the structures of drug trafficking routes involving body packing in China and aims to provide a comprehensive examination of body packing activity, including the pattern of geographic routes and the characteristics of captured body packers. A generalized inflated negative binomial model is also used to investigate the effects of legal and extra-legal factors on the length of sentence for captured body packers.

RESULTS

We identified three types of trafficking routes involving body packing: intra-provincial, inter-provincial, and international. Our results showed that heroin and methamphetamine are the two primary drugs trafficked by captured body packers. Network analysis revealed that among body packing routes, there are three major hubs that serve as the primary origin for the trafficking -Yunnan, Sichuan, and Myanmar- and three potential authorities- Guangdong, Xinjiang, and Sichuan-which serve as the common destinations of the drug routes. Consistent with previous studies, our research also demonstrated that heavier punishments are given in cases that involve a larger quantity of drugs and repeat offenders. Offenders who fall into special groups, such as pregnant/lactating women, the disabled, or minors, receive more lenient sentences. In addition, our analysis further revealed that the logic behind longer sentences for those offenders who confessed as opposed to those who did not, is possibly due to the concentration of imprisonment values at fifteen years, as many of the confessed body packers are sentenced to the maximum fixed term of imprisonment.

CONCLUSION

By narrowing the gap in knowledge on the topic of body packing, our analysis provides evidence-based strategies for fighting against body packing, specifically by identifying geographical patterns and the profiles of captured body packers.

Added value of lung window in detecting drug mules on non-contrast abdominal computed tomography

We evaluated the added value of lung window in non-contrast computed tomography (CT) of suspected body packers or stuffers. Forty suspected drug mules who were referred to our tertiary toxicology center were included. The final diagnosis of drug mule was based on the detection of packs in stool examination or surgery. Non-contrast CT scans were retrospectively interpreted by two blinded radiologists in consensus before and after reviewing the lung window images. The diagnostic performance of abdominal window scans alone and scans in both abdominal and lung windows were subsequently compared. Seven body packers and 21 body stuffers were identified. The sensitivity, negative predictive value (NPV), and diagnostic accuracy of scans in detection of drug mules (either drug packers or stuffers) raised from 60.7, 52.1, and 72.5 to 64.2, 54.5, and 75.0 %, respectively, with a more number of packs being detected (114 vs. 105 packs). In the body packers group, the diagnostic performance of both abdominal windows scans and combined abdominal and lung windows scans were 100 %. In the body stuffers group, the sensitivity, NPV, and diagnostic accuracy of scans increased from 47.6, 52.1, and 55.0 to 52.3, 54.5, and 57.5 %, respectively, after the addition of lung windows. Reviewing the lung window on non-contrast abdominal CT can be helpful in detection of drug mules.

The role of radiology in diagnosis and management of drug mules: an update with new challenges and new diagnostic tools

Emergency physicians and radiologists have been increasingly encountering internal concealment of illegal drugs. The packages commonly contain powdered solid drugs such as cocaine, heroin, methamphetamine and hashish, but they may also contain cocaine in the liquid form. The second type of package has recently been more commonly encountered, and poses a greater diagnostic challenge. As clinical evaluation and laboratory tests frequently fail to make the correct diagnosis, imaging examination is typically required. Imaging methods assume a vital role in the diagnosis, follow-up and management. Abdominal X-ray, ultrasonography, CT and MRI are used for the imaging purposes. Among the aforementioned methods, low-dose CT is state-of-the-art in these cases. It is of paramount importance that radiologists have a full knowledge of the imaging characteristics of these packages and accurately guide physicians and security officials.

Imaging of drug smuggling by body packing

Body packing, pushing, and stuffing are hazardous practices with complex medicolegal and social implications. A radiologist plays both a social and a medicolegal role in their assessment, and it should not be limited only to the identification of the packages but must also provide accurate information about their number and their exact location so as to prevent any package remains in the body packer. Radiologists must also be able to recognize the complications associated with these risky practices. Imaging assessment of body packing is performed essentially through plain abdominal X-ray and computed tomography scans. Ultrasound and magnetic resonance imaging, although with some advantages, actually have a limited use.

Body packing: a review of general background, clinical and imaging aspects

To avoid detection at border crossings or airport customs, drug trafficking is increasingly performed by intra-corporeal concealment. Body packers may ingest packets of varying size and containing varying drugs (mostly cocaine, heroin and cannabis) mixed with other compounds, while body pushers will insert packets in the rectum or vaginal cavity. Body packing may lead to potential life-threatening complications with acute overdose syndromes after packet rupture and intestinal obstruction with possible ensuing bowel rupture being the most significant complications. Physicians including radiologists should be aware of the capabilities of imaging techniques to screen for presence of drug packets as well as the potential complications. Although conventional radiography has long been and still is the most important imaging modality for screening for presence of intestinal packets, the better test characteristics in conjunction with the decreasing radiation exposure, will likely render computed tomography (CT) more important in the future. For imaging of symptomatic patients, CT already is the modality of choice. Besides these modalities, ultrasound and magnetic resonance imaging will be discussed in this paper, together with more general background and clinical information.

Radiological and practical aspects of body packing

Body packing represents the concealment of illegal substances in a person's body with the aim of smuggling. "Body packers" either swallow drug-filled packets or introduce drug-filled packets into their bodies rectally or vaginally with the purpose of concealing them. The three main smuggled drugs are cocaine, heroin and cannabis products. Body packing represents a serious risk of acute narcotic toxicity from drug exposure, intestinal obstruction owing to pellet impaction and bowel perforation with consequent abdominal sepsis. A suspected body packer is generally admitted to hospital to perform imaging investigations and confirm the presence of drugs in his/her body. Radiological imaging methods are essential to diagnose body packing and to detect potential complications. Increasing sophistication of traffickers and improvements in packaging add to the detection difficulty. Radiologists should be aware of the appearance of drug packets in a range of imaging modalities. This article informs physicians about the challenging aspects of body packing, its background and medicolegal issues, what imaging methods can be used and what criteria are necessary to perform a correct diagnosis.
