Abstract
Foreign
body ingestion is common in children. Sharp
foreign bodies are potentially harmful and can result various complications. An
8-month-old infant presented with incarcerated umbilical hernia. With a
suspicion of strangulation, operation was performed that revealed a loop of
ileum being stuck in the umbilical defect. The loop of ileum was freed from the
umbilicus which demonstrated open ends of safety pin piercing out of bowel
lumen. The enterotomy followed by removal of safety pin was performed.
Key
words: Safety pin ingestion, Strangulated umbilical hernia, Intestinal
perforation
Introduction
Sharp
foreign bodies in alimentary tract can produce a number of complications that
often need surgery. The diagnosis is often overt while dealing with the
complications. The presentation of safety pin as incarcerated inguinal hernia
is seldom reported, however, its presentation as incarcerated umbilical hernia
is never described in English literature [1-4]. We are reporting a case of open
safety pin ingestion presenting with incarcerated umbilical hernia.
Case
report
An
8-month-old male infant presented with incarcerated umbilical hernia. The umbilical
hernia was initially reducible but for a day it turned irreducible. General
physical examination was unremarkable (Temp 99F, Pulse 90/min, respiration rate
25/min, BP within normal limits). Abdominal examination showed abdominal
tenderness around umbilicus and an irreducible umbilical hernia. Laboratory
investigations were normal. Ultrasound of the abdomen pointed a loop of bowel being
stuck in the umbilicus. X ray abdomen was not performed.
Operation
was performed by making semi-lunar infra-umbilical incision that revealed a
loop of mid ileum entrapped at the umbilicus. The loop of ileum was reduced.
Further exploration revealed an open safety pin causing perforation of the
ileum (Fig 1). The safety pin was removed by an enterotomy at the site of
perforation. The enterotomy was then closed. Umbilical hernia was also
repaired. The postoperative recovery was uneventful.

Discussion
Various
sharp FBs that are ingested include safety pins, sewing needles, hair pin,
nails etc. In many cases the sharp FB cause complications. The reported
complications are esophageal perforation leading to mediastinitis, pneumothorax,
pneumomediastinum, secondary tracheoesophageal fistula, gastric perforation,
perforation of small and large bowel leading to peritonitis, heart perforation,
duodenocolic fistula, incarcerated inguinal hernia, and the like [1-4]. Rarely,
ingested sharp FB presents with incarcerated inguinal hernia [4]. In our case
the patient developed incarcerated umbilical hernia due to inflammation and
adhesions resulting from the small bowel perforation by open safety pin. The
presentation of ingested safety pin as incarcerated umbilical hernia is a rare
event and not reported before.
