Complications in lymph node excision in the head and neck area.

ABSTRACT

BACKGROUND: Although needle biopsy is widely used in work-up of lymphadenopathy, lymph node excision (LNE) is often required especially in lymphoma diagnostics. LNE is an invasive procedure, which carries a potential risk of complications. However, comprehensive studies evaluating the spectrum and occurrence of complications are lacking. AIMS/OBJECTIVES: This study addresses the role of preoperative needle biopsies in patients who underwent LNE. Furthermore, surgical complications related to LNE are analyzed. MATERIALS AND METHODS: Altogether 321 patients, who underwent LNE in two-year period in 2018-19, and fulfilled our study criteria, were included. Patients' data were retrieved from the electronic patient records. RESULTS: The surgical complication rate was 5.9%. Most of the complications (n = 16; 84.2%) were categorized as minor (I-II) according to the Clavien-Dindo scale. The remaining three (15.8%), all hemorrhages, were categorized as major complications and required intervention. Preoperative needle biopsy might have avoided the need for LNE in some patients, which we discuss in this study. CONCLUSIONS AND SIGNIFICANCE: Surgical complications after LNE in the head and neck area are rare and mostly minor. Needle biopsy is often recommended preoperatively to avoid unnecessary operations and to refrain performing LNE for patients with non-lymphatic malignancy.
