Sir: Seroma formation after lymph node surgery is an all-too-frequent complication. Management options that have included quilting sutures, suction drainage, and fibrin glue have all been associated with morbidity and lengthy hospital stays. An innovative option for the treatment of freely draining seromas was reported in a past issue of Plastic and Reconstructive Surgery, describing the simple use of a stoma bag placed over the area to aid drainage and provide a means of controlled drainage that is able to be applied, changed, and completely managed in the community.1 We have found this technique to be highly useful in this setting of seromas that are freely draining, and sought the benefit of an adjunctive technique for closed, nondraining seromas. We have since expanded the applicability of this “stoma-bag” technique to more complicated scenarios. Although closed seromas are widely treated with inpatient drainage, we describe a technique for community or outpatient drainage to aid the application of a stoma bag for drainage. The technique requires little more than a sterile environment and a disposable intravenous cannula. Under aseptic technique, a 21-gauge intravenous cannula is passed through the skin into the seroma cavity, until flashback of fluid is seen. The needle introducer is removed and the plastic cannula is left in situ for ongoing drainage. A stoma bag is placed over the cannula to collect fluid according to the previously reported technique (Fig. 1). Simple dressings can hold the cannula in place or sutures can be used if preferred.Fig. 1.: Freely draining axillary seroma, with a 21-gauge plastic cannula having been passed through the skin into the seroma cavity, and a stoma bag placed over the cannula for ongoing drainage.We have used this technique in a range of clinical settings, including seromas accumulating after lymphadenectomy, sentinel node biopsy, large flap donor or recipient sites, and other surgically created cavities. The technique is of particular utility where there is a negative-pressure dressing applied to a wound but where an adjacent cavity is not drained by the suction dressing: in such a setting, the negative-pressure dressing can remain in situ without loss of vacuum seal. The stoma bag technique is thus applicable to a range of clinical scenarios, without necessitating open drainage and its associated morbidity, operating room access, or inpatient stay.
