A retrospective analysis of post‐operative outcomes in a series of 108 labial gland biopsies

Abstract

Aim: Histopathological assessment of labial salivary glands has long been a core part of the diagnostic criteria for Sjogren's Syndrome. Biopsy of labial salivary glands is technique sensitive and has post-operative complications which can affect the patient's quality of life. Varying techniques for labial gland biopsy and associated complications are described in the literature. This article gives a step-by-step account of an effective technique for labial gland biopsy as described by Daniels in 1984 and provides a retrospective analysis of the post-operative complications in a series of 108 labial gland biopsies. Materials and methods: A retrospective, post-operative telephone survey was carried out to study the post-operative complications of labial gland biopsies performed by a single operator. All consecutive patients (180) who had labial gland biopsies between October 2010 and August 2012 at the Department of Oral Medicine at Guy's Hospital were called, and 108 surveys were successfully completed. The telephone questionnaires aimed to find out medium and long-term complications of labial gland biopsies to include subjective measures of post-operative pain, swelling and paraesthesia. Results: One patient out of 108 patients (0.9%) reported pain that lasted ≥ 6 months, and six patients (5.5%) reported swelling that lasted > 2 weeks. Three patients (2.8%) reported paraesthesia lasting ≥ 6 months with a median bother score of 0. All biopsies provided sufficient glands to allow for histopathological diagnosis. Conclusions: This article describes a safe and effective technique for labial gland biopsy. Despite a low complication rate, informed consent is essential. Clinical relevance Scientific rationale for studyLabial gland biopsy (LGB) is an important component in the diagnosis of Sjogren's Syndrome. It is technique-sensitive and has post-operative complications which can affect the patient's quality of life. Principal findingsThis article provides a retrospective analysis of the post-operative complications in a series of 108 LGB carried out using a technique which has proved to be effective in delivering histopathological diagnosis and has a low level of post-operative complications. bs_bs_banner Oral Surgery ISSN 1752-2471 2 Oral Surgery 8 (2015) 2-9. Practical implicationsThis article gives a step-by-step account of an effective technique for LGB which can be used by clinicians, as well as rates of post-operative complications which are useful when obtaining informed consent from the patient.
