RT Journal Article SR Electronic T1 Plastic bag clip discovered in partial colectomy accompanying proposal for phylogenic plastic bag clip classification JF BMJ Case Reports FD BMJ Publishing Group Ltd SP bcr0220113869 DO 10.1136/bcr.02.2011.3869 VO 2011 A1 Larisa M Lehmer A1 Bruce D Ragsdale A1 John Daniel A1 Edwin Hayashi A1 Robert Kvalstad YR 2011 UL http://casereports.bmj.com/content/2011/bcr.02.2011.3869.abstract AB A plastic bag clip was incidentally found anchored in the mucosa of a partial colectomy specimen 2.6 cm proximal to a ruptured diverticulum for which the patient, a mentally retarded, diabetic, 58-year-old man, underwent surgery. Over 20 cases of accidental ingestion of plastic bag clips have been published. Known complications include small bowel perforation, obstruction, dysphagia, gastrointestinal bleeding and colonic impaction. Preoperative diagnosis of plastic clips lodged in the gastrointestinal tract is frustrated due to radiographic translucency. This occult threat could likely be prevented by the design of gastrointestinally safe, plastic-bag-sealing devices. Presented here is a morphologically based classification of bag clips as a possible guide for determining the most hazardous varieties and to aid further discussions of their impact on health.
