Limited Flexor Sheath Incision and Drainage in the Emergency Department in the Management of Early Pyogenic Flexor Tenosynovitis.

BACKGROUND

Pyogenic flexor tenosynovitis (PFT) has been considered a surgical emergency. Varying operative approaches have been described, but there are limited data on the method, safety, and efficacy of nonoperative or bedside management. We present a case series where patients with early flexor tenosynovitis are managed using a limited flexor sheath incision and drainage (I&D) in the emergency department (ED) to both confirm purulence within the flexor sheath and as definitive treatment.

METHODS

A retrospective study of all patients clinically diagnosed in the ED with flexor tenosynovitis at our institution from 2012 to 2019 was performed. Patients with frank purulence on examination were taken emergently to the operating room (OR). Patients with equivocal findings underwent limited flexor sheath I&D in the ED. Safety and efficacy were studied for patients with early flexor tenosynovitis managed with this treatment approach.

RESULTS

Thirty-four patients met the inclusion criteria. Ten patients underwent direct OR I&D, and 24 patients underwent ED I&D. In the ED I&D group, 96% (24 of 25) of patients did not have frank purulence in the flexor sheath and were managed with bedside drainage alone. There were no procedural complications and no need for repeat operative intervention. Time to intervention (3.1 hours vs 8.4 hours) was significantly shorter for the ED I&D group compared with the OR I&D group. Within the ED I&D group, 86% of patients exhibited good/excellent functional scores.

CONCLUSIONS

Limited flexor sheath I&D in the ED provides a potential safe and effective way to manage patients with early flexor tenosynovitis.
