Sialendoscopy - a diagnostic and therapeutic approach subjectively rated by patients

Development of a patient reported outcome instrument for chronic sialadenitis

BACKGROUND

Sialendoscopy assisted treatments are a minimally invasive management modality for chronic sialadenitis. Clinicians report improved patient quality of life (QoL) following sialendoscopy assisted treatments, but there exist gaps in current literature about patient reported outcomes (PROs). PROs are outcome measures developed based on patient perceptions.

OBJECTIVE

The objective of this study was to create a PRO instrument for chronic sialadenitis, to assess the efficacy of sialendoscopy assisted treatments in improve patients' QoL.

DESIGN

This four-phase qualitative study employed grounded theory methodology and a modified Delphi technique. In Phase I, ten patients were interviewed to identify the QoL domains impacted by chronic sialadenitis. In Phase II, these QoL domains were presented to a focus group of different chronic sialadenitis patients, who were asked to rank them by order of importance. A conceptual framework of QoL domains impacted by chronic sialadenitis was created based on patient consensus. Itemization of the PRO questionnaire was done by a focus group of four Otolaryngologists in phase III. Lastly, the questionnaire was completed in Phase IV by cognitive interviewing of five new chronic sialadenitis patients; ensuring ease of understanding and clarity.

RESULTS

Patients identified 15 domains of QoL impacted by chronic sialadenitis, divided into three sub-scales: physical symptoms, psychosocial symptoms, and activity restriction. These domains provided the basis for creation of a 22-item PRO questionnaire, with a Likert-type response scale.

CONCLUSION

Clinical application of the novel questionnaire produced by this study will allow for a patient-centered assessment of the patient reported effectiveness of sialendoscopy assisted therapies for management of chronic sialadenitis. Level of evidence Level V.

Sialolithiasis: retrospective analysis of the effect of an escalating treatment algorithm on patient-perceived health-related quality of life

Background

Gland preserving techniques in the treatment of sialolithiasis have continuously replaced radical surgery. The aim of this study was to evaluate a multimodal treatment algorithm in the therapy of sialolithiasis and assess improvement of HRQoL perceived by patients.

Methods

Patients with sialolithiasis were treated by a multimodal treatment algorithm based on multiplicity of stones, stone size, affected gland, and stone position. The therapeutic spectrum ranged from conservative measures, extracorporeal shockwave lithotripsy, interventional sialendoscopy, combined endoscopic-surgical procedures to surgical gland removal as ultima ratio. Outcomes were evaluated by surgeons by means of the electronic patient record and by patients themselves using a standardized questionnaire.

Results

87 patients treated for sialolithiasis were comprised in this study. The submandibular gland (SMG) was affected in 58.6% and the parotid gland (PG) in 41.4% of cases. Mean patient age was 41.67 years for SMG and 48.91 years for PG. In over 80% of cases sialolithiasis was associated with classic meal-related pain and swelling. Type and intensity of symptomatic sialolithiasis were not dependent on patient age or gender, nor could a relation between the affected gland and the occurrence of symptoms be demonstrated. Overall, 86.2% of cases were reported as cured using the multimodal step-by-step treatment algorithm. Resection of the affected gland could be dispensed in 98.9% of cases. According to patients pain could be reduced in 94.3% of cases.

Conclusions

The analyzed treatment algorithm of increasing invasiveness is a favorable and effective tool to successfully treat sialolithiasis in > 86% of cases. For the first time, the present study shows that patient-perceived improvement of HRQoL due to ease of symptoms has an even higher success rate of > 94%.

Success of minimally invasive salivary gland surgery-Quality of life, prognostic factors

OBJECTIVE

Goal of this study was to investigate, whether sialendoscopy in obstructive salivary gland disorders affects patients' oral health-related quality of life compared to healthy individuals, and to determine factors that might influence this relationship.

STUDY DESIGN

Retrospective observational study.

SETTING

University of Kiel, Department of Otorhinolaryngology, Head and Neck Surgery.

SUBJECTS AND METHODS

A group of 130 patients, undergoing sialendoscopy between 01/2004 and 06/2017 was considered. Oral health-related quality of life was assessed using the OHIP-G14 (Oral Health Impact Profile) in combination with a custom-made questionnaire on satisfaction and success in relation to sialendoscopy.

RESULTS

Oral health-related quality of life of patients without dentures or with removable dentures was significantly worse than in the healthy population, whereas the necessity of multiple additional follow-up treatments was associated with worse oral health-related quality of life. No essential predisposing factors were identified. Average satisfaction with the intervention was observed to be x̅ = 4.33 (SD = 3.69) on a visual analogue scale from 1 (=very satisfied) to 10 (=very unsatisfied). A longer follow-up period and a higher patients' age were positively related, whereas removal of salivary gland during follow-up was negatively related to satisfaction. In 113 cases (86.9%) long-term preservation was accomplished and 115 (88.5%) patients would repeat a sialendoscopy in case needed.

CONCLUSION

In summary, sialendoscopy resulted in long-term high subjective and objective success rates. However, oral health-related quality of life scores did not reach those levels found in the healthy population.

Sialendoscopy under conscious sedation versus general anesthesia. A comparative study

OBJECTIVE

Sialendoscopy is a minimally invasive emerging approach, the general surgical technique has been published but many essential questions still need to be addressed with the aim of improving outcomes. For instance, should we systematically perform sialendoscopy under conscious sedation (CS) or general anesthesia (GA)? What are the limitations of CS? The objective of this study is to compare these two modalities.

METHODOLOGY

A retrospective study of 70 patients who had undergone a sialendoscopy between 2014 and 2016 (34 under GA and 36 under CS). Comparisons were made between these two groups in term of operative time, stone size and location, tolerability, operative success and post-operative pain.

RESULT

The patients' mean age was 45.33 years. The operative success rate among the GA group was 79.4% vs. 88.9% in the CS group (P = 0.276), while complications for both groups were comparable. All patients considered the intervention under CS to be tolerable.

CONCLUSION

Sialendoscopy under CS or GA demonstrated the ability to access large and distal stones among the different salivary glands with an excellent tolerability. Anesthesia type should be based on surgeon and patient preference Nevertheless, patient reassurance and surgeon experience are important to producing a good result with CS.

The significance of ductoscopy of mammary ducts in the diagnostics of breast neoplasms

Introduction

Ductoscopy is a low invasive method enabling the diagnostics of intraductal proliferative lesions in breasts. Fiberoptic ductoscopy (FDS) is important in the diagnosis of patients with pathological nipple discharge. There are attempts to apply FDS in patients with breast cancer without the presence of nipple discharge.

Aim

To assess fiberoptic ductoscopy in the diagnostics of breast neoplasms.

Material and methods

The material was composed of a group of 164 patients treated for intraductal proliferative lesions in breasts. In the analyzed group of patients, FDS was conducted in 128 patients with pathological nipple discharge and 36 patients with the presence of breast cancer. The analyzed period was divided into three sub-periods. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of FDS examination verified by post-operative histopathological examination were analyzed. The safety of the method was also assessed, taking into consideration the complications.

Results

An increasing number of successful ductoscopies together with the number of performed FDS examinations was noted. There were statistically significant differences in the percentage of successful cannulations in relation to the number of performed FDS examinations in the three subsequent stages of the project (p = 0.011). The duration of FDS examination in the third period was reduced in comparison with the first and second period (p < 0.001). Sensitivity of fiberoptic ductoscopy is 68.1%, specificity 77.3% and PPV 90.4%, but NPV is 44.1%.

Conclusions

The introduction of fiberoptic ductoscopy in our clinic has contributed to the widening of the diagnostic possibilities of small intraductal lesions of the mammary gland.
