Complications of labial minor salivary gland biopsy and comparison of complications in patients with and without primary Sjögren's syndrome

Objectives: Labial minor salivary gland biopsy (MSGB) is a procedure in which complications such asbleeding, hematoma, numbness, wetness can be seen after the procedure. It is not known whether thesecomplications have changed in patients with primary Sjögren's syndrome (PSS). The aim of this study is toinvestigate the frequency of complications after the labial MSGB and to investigate whether thesecomplications has changed in PSS.Methods: Participants with a preliminary diagnosis of PSS who underwent a labial MSGB without any suturewere included in the study. One month after the procedure, the complication screening questionnaire wasadministered face-to-face interview or by telephone. All complications were compared between PSS and nonPPS groups.Results: Complications screening questionnaire was applied to 99 participants (face to face with 79 participantsand by telephone with 20 participants). After the procedure, 17.2% of the participants had uncomfortablebleeding, 2.0% had persistent numbness which continues more than 1 week and 1.0% had wetness andhematoma. Bleeding duration was more than 1 hour in 11.1% of the participants. Complications were notdifferent between PSS and non-PSS groups (p > 0.05).Conclusions: After the labial MSGB procedure without suturing, uncomfortable bleeding is frequent and theduration of bleeding is long, but complications other than bleeding are rare. The incidence of complicationsafter labial MSGB procedure was not different in participants with PSS than in those without PSS.
