Don’t Get Hung Up on Fishhooks: A Guide to Fishhook Removal

Fishing is one of the world’s most beloved activities, enjoyed as a sport or a leisure activity. However, a common injury from fishing is embedment of the fishhook in the cutaneous tissue. Barbed fishhooks are used for their effectiveness in maintaining the fish on the hook once it is caught, but when implanted in the hand of a fisherman or fisherwoman, barbs can pose problems for removal without exacerbating internal tissue injury. Nevertheless, dermatologists should not shy away from removal of barbed fishhooks, as there are several simple methods that can be easily utilized in the outpatient setting.

Case Report

A 68-year-old man presented to an outpatient dermatology clinic after sustaining a barbed fishhook injury while fishing. The fishhook was firmly inserted into the ventral side of the third digit of the right hand (Figure 1).

Prior to presenting to dermatology, the patient went to 2 urgent care clinics the same day seeking treatment. He reported that practitioners at the first clinic were not able to remove the fishhook because they did not have pliers in stock. At the second clinic he was told the fishhook might be embedded in deeper tissues and was advised to go to the emergency department at the local hospital. When he arrived at the emergency department, a 6-hour wait time prompted him to see a local dermatologist instead.

To remove the fishhook, the area was cleaned and prepared first; lidocaine 2% was administered for local anesthesia. An 18-gauge needle was then advanced through the puncture site parallel to the fishhook’s inner shaft on the same side as the barb, which could be successfully palpated using the tip of the 18-gauge needle. The tip of the needle was then used to cap the barb beneath the skin. This technique allowed for the hook to be easily extracted in a retrograde manner without causing further destruction to the surrounding tissue. The patient then was started on prophylaxis cephalexin 500 mg 3 times daily for 3 days.

Comment

The hand is the most common site of fishhook injury, followed closely by the head and eyes.¹ Barbless fishhooks usually can be removed by pushing the hook in a retrograde manner along the path of insertion. This method is simple and rarely results in complications. However, there are no guidelines for removal of barbed fishhooks. Furthermore, removing a barbed fishhook in the same retrograde manner would result in extensive internal tissue destruction and increased complications. Due to the popularity of the sport of fishing, fishhook injuries, depending on geographical location, are not uncommon.² For this reason, trauma and emergency practitioners have become well versed in safe methods for barbed fishhook removal. However, patients are not always able or willing to seek medical care in emergency departments and may opt to seek treatment in outpatient settings, such as in our case. As a result, dermatologists should familiarize themselves with safe and effective fishhook removal methods, as they are not time consuming and do not require complex equipment. Failure to treat the patient may lead to further patient discomfort and increased risk for complications. Additionally, many of the techniques for removal may be useful with other foreign bodies embedded in cutaneous tissue (eg, splinters).

There are a number of safe and effective techniques for removing barbed fishhooks from cutaneous tissue, including the advance-and-cut method, the cut-it-out technique, the string-pull method, and the needle cover technique.^1-3 The method chosen to remove the fishhook is dependent on a variety of factors, such as anatomic location, tissue depth, and provider comfort.

With the advance-and-cut method (Figure 2), the affected area is anesthetized and a small incision in the skin is created to expose the barb. The fishhook is then advanced through the incision, providing visibility of the barb and thus allowing the practitioner to cut the barbed tip without creating further damage to the surrounding tissue. The shaft of the fishhook can subsequently be removed in a retrograde fashion. The advantages of this technique include that it may be successfully used in all types of barbed fishhooks and it provides the practitioner with direct visibility of the barb, thus minimizing risk for neurovascular injury during removal.¹ However, the primary disadvantage is that a second cutaneous wound is created in exposing the barb.

The cut-it-out technique (Figure 3) is similar to the advance-and-cut method in that they both require anesthesia along with creating an incision. With this method, a scalpel is used to create a small linear incision originating at the fishhook entrance site and ending at the approximated location of the fishhook’s tip. The fishhook then is simply lifted superiorly in a retrograde fashion.
