A 42-year-old male presented to the emergency surgery room (ESR) with complaint of accidental mercury ingestion. As recorded by a glass mercury thermometer, the patient was febrile for 3 days before admission. He had a history of stroke 6 months prior, the sequelae of which, a sudden spastic attack, resulted in accidental chewing of the thermometer. The patient also had an indwelling percutaneous endoscopic gastrostomy (PEG) for severe dysphagia post the episode of stroke.
On examination, the patient was conscious and alert. He was given a gentle head-low position, and X-ray of the chest and abdomen was done to confirm the diagnosis. In view of the diagnosis, the patient was taken up for an emergency upper gastrointestinal (GI) tract endoscopy to retrieve the mercury and prevent its systemic absorption and toxicity. The procedure was done under total intravenous anesthesia (TIVA).
The mercury in the patient's stomach was aggregated in the fundus using the flush technique. An attempt to use the 1-mm suction channel of a flexible endoscope was futile due to the high surface tension of mercury.  The operating surgeon therefore used the existing PEG tube to retrieve the mercury. The tube was moved in a retrograde manner to reach the mercury that had been re-collected in the fundus [Figure 1]. Suction was applied to the PEG tube after establishing contact between the mercury and the funnel end of the tube [Figure 2]. Three sittings ensured complete clearance of the mercury. This was confirmed post-operatively by an X-ray of the abdomen.

Mercury removal from the GI is an extremely challenging task, requiring emergency expertise. The heavy metal with its large number of side effects, , when exposed to, may be lethal. Despite the ban on mercury-containing instruments by the Ministry of Health and Family Welfare over 2 years ago,  mercury glass thermometers are still very much in use in most government hospitals. Usage of mercury thermometers on a day-to-day basis especially among certain groups of patients, such as children, psychiatric patients, and those with a history of cerebrovascular accidents, can result in dangerous situations such as the one mentioned above. To prevent any such mishaps and to reduce the environmental hazards of mercury, we advise replacement of existing glass thermometers with digital ones.
Accidental mercury ingestion is a rare presentation, with no set protocol for its management. On the basis of our case, we recommend immediate head-low position before any intervention can be undertaken. Funneled or wide-bore tubes must be used for suction of the heavy metal to break its high surface tension.
