Timing of Button Battery Removal From the Upper Gastrointestinal System in Children.

OBJECTIVE: The aim of the study was to investigate the appropriate time of removal of button batteries (BB) from the esophagus and stomach in children. METHODS: This is a retrospective descriptive single-center study reviewing the medical records of all children with BB ingestion seen in the Royal Hospital between January 1, 2011, and December 31, 2014. All children younger than 13 years with a history of BB ingestion were included. Biodemographic data including age and sex were obtained. In addition, time of ingestion of BB, location of BB, time of endoscopic removal, and any complications were recorded. RESULTS: Forty-six patients with BB ingestion were identified out of 385 who presented with foreign body ingestion (12%) during the study period. Twenty four (52%) were boys and 22 (48%) were girls. All children had BB of 20 mm in diameter. Two children had the BB in the esophagus, whereas 13 children had the BB in the stomach up on presentation. The mean time of presentation of children with BB in the esophagus was 1.75 hours after ingestion, whereas those with BB in the stomach presented on average 19.4 hours after ingestion (P < 0.035). An endoscopic intervention was done in only 8 of the 46 children. Two children had the BB in the esophagus and 6 children in the stomach. One child required intensive care unit with subsequent esophageal strictures. The mean time of esophageal BB removal was 1.7 hours from ingestion, whereas removal from the stomach was on average 27 hours after ingestion. Endoscopic injuries were noted in 87.5% of the children with BB in the esophagus or the stomach. No mortality occurred during the study period. CONCLUSIONS: Button batteries ingestion is a common problem with variable time of presentation to the emergency department. Esophageal BB presents the highest risk of injury even in as short time as 2 hours. Gastric mucosal injury can occur within 10 hours of ingestion. Button batteries of 20-mm diameter need to be urgently removed from the esophagus and be considered for removal earlier than 24 hours if in the stomach.

Patterns and Complications of Ingested Foreign Bodies in Omani Children.

OBJECTIVES: We sought to describe the frequency of encounters and complications of foreign body (FB) ingestion in children seen at Royal Hospital, Oman. METHODS: Medical records of all children (≤ 13 years) who presented to Royal Hospital between 1 January 2011 and 31 December 2014 diagnosed with FB ingestion were reviewed. Children with FBs in their mouth or airway, with esophageal food impaction, and caustic ingestion were excluded from the analysis. Parameters including age, sex, type of FB, anatomical location of the FB on X-ray, endoscopic findings, and all complications were reviewed. RESULTS: Of the 585 children diagnosed with FB ingestion, 385 were included in the study; 58.4% were males and 41.6% were females giving a male to female ratio of 1.4:1.0. Half (50.9%) of the children were less than three years old. Coins were the most frequently ingested objects (41.3%) followed by disc batteries (12.2%). Sixty-three patients (16.3%) required urgent esophagogastroduodenoscopy (EGD). EGD was performed mainly for coins (44.4%) followed by disc batteries (14.3%) in the esophagus or stomach. The complication rate was 5.2% in total, and 3.6% for clinically significant complications. We had no mortality cases. CONCLUSIONS: FB ingestion is common in toddlers in Oman. Coins and disc batteries are most commonly ingested calling for strict family vigilance. Endoscopy is done in a small number of children and clinically significant complications, in general, are low. However, these findings should not lead to a false sense of security, and ingested FBs should always be taken seriously.
