Inguinal and umbilical hernias are two of the most common reasons a primary care patient may need referral to a general surgeon. History and physical examination are usually sufficient to make the diagnosis. Patient symptoms include pain, burning, heaviness, or aching in the groin or umbilical region. It may be worse at the end of the day or after prolonged activity. The patient may also report a bulge that often disappears in the prone position.

It is best to examine the patient standing and then lying supine. Usually, with the patient standing, a visible asymmetry is seen. This can disappear when the patient is lying flat. Physicians can also feel the bulge or impulse when the patient coughs or strains.

The surgeon’s diagnosis and subsequent treatment decisions are reliably made by the patient history and physical examination alone. The routine use of imaging, including ultrasound, in the setting of a clinically palpable inguinal or umbilical hernia is not required. This only adds unnecessary costs and treatment delay with no useful contribution to management decisions.

Choosing Wisely is a global movement for reducing unnecessary tests and treatments in health care. It tries to inspire and engage health care professionals to take the lead in reducing unnecessary tests, treatments, and procedures, and enables them with simple tools and resources that make it easier to choose wisely.

Recommendation

The Fraser Health Authority Division of General Surgeons, with the support of the Section of General Surgeons of BC, recommends avoiding the routine use of ultrasound in the evaluation of clinically apparent inguinal and umbilical hernias. We are happy to accept elective referrals without an ultrasound. If the referring physician is not confident in the diagnosis, it is okay to order an ultrasound. Also, if the physician feels an ultrasound is necessary, it can be ordered at the time of initial consultation.

Above is the information needed to cite this article in your paper or presentation. The International Committee of Medical Journal Editors (ICMJE) recommends the following citation style, which is the now nearly universally accepted citation style for scientific papers:
Halpern SD, Ubel PA, Caplan AL, Marion DW, Palmer AM, Schiding JK, et al. Solid-organ transplantation in HIV-infected patients. N Engl J Med. 2002;347:284-7.

About the ICMJE and citation styles

The ICMJE is small group of editors of general medical journals who first met informally in Vancouver, British Columbia, in 1978 to establish guidelines for the format of manuscripts submitted to their journals. The group became known as the Vancouver Group. Its requirements for manuscripts, including formats for bibliographic references developed by the U.S. National Library of Medicine (NLM), were first published in 1979. The Vancouver Group expanded and evolved into the International Committee of Medical Journal Editors (ICMJE), which meets annually. The ICMJE created the Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals to help authors and editors create and distribute accurate, clear, easily accessible reports of biomedical studies.

An alternate version of ICMJE style is to additionally list the month an issue number, but since most journals use continuous pagination, the shorter form provides sufficient information to locate the reference. The NLM now lists all authors.

BCMJ standard citation style is a slight modification of the ICMJE/NLM style, as follows:

  • Only the first three authors are listed, followed by "et al."
  • There is no period after the journal name.
  • Page numbers are not abbreviated.
