Abstract

We report a case of small bowel obstruction secondary to coin ingestion. A 22-year-oldwoman presented to the Emergency Department (ED) with a 3-week history of abdominal pain. Upon initial history the patient denied any foreign body ingestion. Only after computed tomography (CT) scanning of the abdomen and pelvis did the patient admit to deliberate ingestion of a single United States penny coin. During surgical evaluation it was found that the coin had lodged near the ileocecal valve and an inflammatory mass had formed around the intraluminal coin, causing a 10 × 7 cm fibrous tumor to completely obstruct the small bowel. It is thought that oxidation of the coin, with subsequent exposure of its high zinc content, instigated the inflammatory cascade.

Introduction

Small bowel obstruction is an important cause of abdominal pain in Emergency Department (ED) patients. Common causes include postoperative intra-abdominal adhesions, hernias, and occasionally neoplasms. Less commonly, foreign body ingestions have been reported as the etiology of obstruction. In recent years, there have been reports of small bowel obstruction due to organic material such as fruit pits and crustacean shells, and inorganic material such as dental molds, vascular grafts and postoperative hardware (1, 2, 3, 4, 5, 6).

Case report

The patient was a 22-year-old woman presenting with a 3-week history of worsening abdominal pain. She described the pain as sharp, intermittent, located in the right lower quadrant with no alleviating or exacerbating factors, and associated with intermittent vomiting. During this time, she described a 10-pound weight loss. She had normal bowel movements and flatus, with the last bowel movement being 6 h before arrival. Approximately 1 week before presentation she was seen in another hospital ED

Hospital course

At operation, the terminal ileum was found to be grossly fibrotic with a bowel wall thickness of 3.0 cm. There was a large stricture at the ileocecal valve where a partial perforation due to a rusted copper penny was found. Resection of 25 cm of the distal ileum was done. There was no indication of prior ileocecal valve stricture (see Figure 2).

Discussion

Small bowel obstruction is a common problem encountered in the evaluation of ED patients who present with significant abdominal pain, nausea and vomiting. As many as 20% of patients admitted to a surgical service for acute abdominal pain are found to have bowel obstruction (7). Obstruction may be mechanical or due to adynamic ileus. Approximately 50% of mechanical obstructions are due to postoperative intra-abdominal adhesions, with hernias, neoplasms, and inflammatory processes or strictures

    Coins are the most commonly ingested foreign body among paediatric populations [1,2]. Although most ingested coins are either passed spontaneously or retrieved with medical intervention, without serious consequence, there is potential for serious morbidity and mortality to occur if the coins remain in the gastrointestinal tract [3–7]. Complications can include stricture formation, oesophageal perforation, tracheo-oesophageal fistula and aorto-oesophageal fistula [8].

    In fewer than 10% of cases, foreign bodies may impact within the intestines [15]. Foreign body impaction may result in complications such as mucosal abrasions within the gastrointestinal tract, bleeding, gastric outlet obstruction, oesophageal or gastrointestinal perforation and secondary mediastinitis, peritonitis, abscess or fistula formation [16–19]. Therefore, impaction is generally a strong indication for foreign body removal.

    This may give a false impression of the coins being in the colon, just as in our case (6,7). Coins may become impacted at sites of gastrointestinal tract narrowing like the proximal or distal esophagus and terminal ileum, leading to perforation or the development of an inflammatory mass, leading to bowel obstruction (6,12–14). After absorption, zinc concentrates in the liver, pancreas, and kidney as well as erythrocytes, hippocampus, cerebellum, prostate and bone, and is excreted primarily via bile and pancreatic juice into the feces (5,19).
