Student tip: This case is useful for showing localization of vomiting. |
Historical data and physical examination findings can help initial characterization of the GI pathology in the vomiting patient.
| Question | Answer | Article | |
| Match the color and content of the vomitus with the likely location of GI pathology and any possible characterization of the problem.
Vomitus: White or clear foamy; Blood streaked white liquid; Dark ‘coffee grounds’; Yellow liquid; Green liquid; Dark brown fetid liquid; Bright red bloody liquid Possible location: Stomach; Upper duodenum; Lower duodenum/ileus; Upper ileum Potential pathology: Acute onset; Intestinal obstruction; Ulceration |
White or clear foamy: stomach; typically acute. Blood streaked white liquid: gastric irritation from vomiting. Dark ‘coffee grounds’: pathologic gastric bleeding, ulceration; metabolic cause possible. Yellow liquid: stomach, digested reflux bile; not acute; metabolic cause possible. Green liquid: upper duodenum, reflux of bile; ileus/obstruction; typically acute. Dark brown fetid liquid: lower small bowel; ileus/total obstruction. Bright red bloody liquid: gastric hemorrhage; acute bleed; ulceration.
