Juvenile Recurrent Parotitis: Video-Documented Sialendoscopy

Juvenile recurrent parotitis (JRP) is characterised by recurrent episodes of painful parotid swelling in children. JRP is the second most common cause of parotitis in childhood, behind only paramyxovirus. The prevention of recurrent attacks represents the most dramatic and serious aspect of this pathology. Since 2004, different authors have evaluated sialendoscopy for the diagnostic and therapeutic management of JRP. In this paper, we share our clinical experience of the use of sialendoscopy for the treatment of JRP. We document with video sialendoscopy the glandular pathology in four children with a mean age of 11.5 years, who had suffered from 3-6 episodes/year of inflammation prior to treatment. The use of sialendoscopy in our patients was effective in preventing recurrences. For the first time, the videosialendoscopy of a series of children diagnosed with JRP is documented in the literature.

Sialendoscopy approach in treating juvenile recurrent parotitis: a systematic review

BACKGROUND

Juvenile recurrent parotitis (JRP) is characterized by recurrent episodes of painful parotid swelling in children. The purpose of this systematic review was to determine the diagnostic and therapeutic effectiveness of sialendoscopy in children affected by JRP.

METHODS

A systematic literature search was performed in PubMed, EMBASE, Scopus and the Cochrane Library until April 2022, without language restrictions or specified start date. Quality assessment was performed using the Newcastle-Ottawa Scale (NOS).

RESULTS

Our review included 524 patients and 646 sialendoscopies. The sample sizes of the different studies ranged from 3 to 77 subjects. Most authors performed sialendoscopy under general anesthesia. The mean percentage of recurrences observed was 25.1% (95% confidence intervals) (CI 23.6-26.6). There was a statistically significant relationship between the number of attacks/year and recurrences (p < 0.05). The percentage of recurrences according to the type of irrigation/flushing used ranged from 22.2% to 25.2%, with no significant differences between the use of corticosteroids alone (25.2% of recurrences), corticosteroids plus antibiotics (25% of recurrences) or saline alone (22.2% of recurrences). Sialoendoscopy has proved in all cases to be a valid method for the diagnosis of JRP, but it does not allow a reliable differential diagnosis with other autoimmune parotitis such as Sjögren's syndrome.

CONCLUSION

According to our results, parotid sialoendoscopy was 74.9% effective as a primary treatment in the prevention of recurrent symptoms in JRP. The type of ductal irrigation used did not significantly influence the prognostic outcome.

Sialendoscopy for pediatric salivary gland disorders: a study of safety and effect

PURPOSE

Sialendoscopy has become the preferred modality for managing pediatric salivary gland disorders (PSGD) including juvenile recurrent parotitis (JRP) and sialolithiasis. The literature remains sparse, but several case series have reported good outcomes and few complications. The aim of this study was to investigate the safety and efficacy of sialendoscopy for PSGD in a Danish setting.

METHODS

From a national sialendoscopy database, we included records of children who had undergone sialendoscopy for PSGD at our clinic over a 6-year period. Clinical and intraoperative data, follow-up and e-mail surveys after 1, 3 and 5 years were retrieved for analysis.

RESULTS

We included 52 procedures on 50 glands (32 parotid, 18 submandibular) in 49 children. Of eligible patients, 90% attended clinical follow-up, 80% answered the survey after 1 year, 80% after 3 years and 60% after 5 years. JRP was diagnosed in 33 cases, obstructive causes in 18 cases. Complications noted were ductal perforation (2%), transient lingual nerve affection (4%) and infection (2%). For JRP patients, overall symptoms had improved for 96% after 3 months, 81% after 1 year and 83% after 3 years. For patients suffering from obstruction, overall symptoms were improved for 93% after 3 months and for 100% after 1 year.

CONCLUSION

Sialendoscopy is a safe procedure for PSGD, and effective for sialolithiasis and symptom reduction in JRP.

Pediatric Sialendoscopy

Purpose of Review

To describe the pathophysiology, evaluation, and management of sialadenitis as well as the indications for and outcomes of sialendoscopy in the pediatric population.

Recent Findings

Pediatric sialadenitis makes up a small proportion of all salivary gland disease. Acute viral sialadenitis and juvenile recurrent parotitis are the most common forms of the condition. Juvenile recurrent parotitis is thought to be multifactorial in etiology with infectious, behavioral, autoimmune, and structural contributions. Review of the current literature supports a potential benefit from sialendoscopy for children with recurrent acute or chronic sialadenitis. Sialendoscopy can provide both diagnostic and therapeutic benefits with very low associated risks. The most common sialendoscopy findings include intraductal sludge or debris, sialoliths, and ductal strictures.

Summary

In the select pediatric population, sialendoscopy is a safe and effective procedure with associated decreased rates of recurrent acute sialadenitis including juvenile recurrent parotitis.

The changing landscape of pediatric salivary gland stones: A half-century systematic review

OBJECTIVE

To assess the evidence for pediatric sialolithiasis, including its demographic characteristics, diagnosis, and demonstrate the shift in its treatment paradigm.

DESIGN

A systematic review of sources from the Medline and Embase databases was conducted from inception to Dec 4, 2020. Two researchers independently extracted data and assessed quality.

PATIENTS

Patients under the age of 18 with sialolithiasis were included.

MAIN OUTCOME MEASURES

Study design, cohort size, age, sex, symptoms, stone characteristics, diagnostic modality and intervention were collected data points.

RESULTS

Forty-one studies with 243 patients were included in the review, of which 40 were case reports or series. Most stones were found in the submandibular gland (n = 210, 85.4%) and were single stones (n = 101, 71.1%). Average stone size was 7.7 mm. The most common diagnostic imaging modality used was ultrasound (n = 73, 47.4%), shifting from plain radiograph which was favoured in earlier years. Similarly, open gland excision was historically preferred, but since 2000, sialoendoscopy comprised 40.5% of all treatment modalities and continues to increase in prevalence, up to 52.1% by 2020. Extracorporeal shock wave lithotripsy was associated with the highest complication rate of 54.2%.

CONCLUSIONS

The pediatric sialolithiasis diagnostic and therapeutic landscape has changed with ultrasound replacing plain radiographs, and sialoendoscopy replacing submandibular gland excision. Further high-level quality evidence research is required to refine the indications, effectiveness, and safety of sialoendoscopy in pediatric sialolithiasis.

Treatment of juvenile recurrent parotitis with irrigation therapy without anesthesia

Purpose

No standardized treatment regimen exists for juvenile recurrent parotitis (JRP). The investigators hypothesized that irrigation with saline only without local anesthesia will be an effective and beneficial option.

Methods

Using a retrospective study design, a series of children with typical symptoms of JRP who were treated with at least one irrigation therapy were evaluated. This treatment consisted of irrigation of the affected gland with 3–10 ml saline solution without any type of anesthesia. The outcome variables were patient/parent satisfaction, frequency and duration of acute JRP episodes, and the need for antibiotics before and after irrigation therapy.

Results

The case series was composed of six boys aged 3.3–7.7 years who experienced one to eight sessions of irrigation therapy. The period of follow-up was 9–64 months. We observed a total resolution of symptoms in two children and an improvement in the other four. No relevant side effects were seen.

Conclusion

Our results suggest that irrigation therapy is a reasonable, simple, and minimally invasive treatment alternative for JRP. In contrast to sialendoscopy or sialography, there is no need for general anesthesia or radiation exposure.

Unilateral Sialendoscopy for Juvenile Recurrent Parotitis: What Happens to the Other Side?

OBJECTIVE/HYPOTHESIS

Current literature has confirmed the benefits of sialendoscopy for the treatment of juvenile recurrent parotitis (JRP). However, this procedure is often performed unilaterally, although the disease can affect both sides. This article investigated the clinical course of the contralateral parotid (CL) gland in children requiring unilateral sialendoscopy with the goal of clarifying the necessity of primary bilateral sialendoscopy.

STUDY DESIGN

Prospective cohort study in a tertiary center.

METHODS

Over an eight-year period, 77 children with JRP underwent unilateral sialendoscopy. We observed the clinical course of the CL parotid over a minimum follow-up period of 24 months. New episodes of sialadenitis were recorded on both sides along with the need for a second sialendoscopy. These data were correlated with the preoperative symptoms of the contralateral side as well as ultrasound (U/S) findings at baseline assessment.

RESULTS

In total, six children required sialendoscopy on the CL side (7.8%), 62 children remained asymptomatic or with scarce swellings (80.5%), and nine children improved (11.7%). The preoperative U/S findings on the CL side positively correlated with the number of postoperative swellings. The proportion of children needing CL sialendoscopy was higher (21.4%) among children needing a second sialendoscopy on the operated side.

CONCLUSIONS

In the long term, the vast majority of children needing unilateral sialendoscopy do not require similar treatment of the CL parotid gland. However, a history of bilateral swellings along with U/S findings of parenchymal disorganization on the CL side significantly increases the risk of needing further sialendoscopy at a later time.

Pediatric sialendoscopy: An 11-year study from a single tertiary care center

OBJECTIVES

To evaluate the suitability, benefits, and limitations of sialendoscopy for pediatric patients.

METHODS

We performed a retrospective analysis of all pediatric sialendoscopy patients (aged 16 years or younger) in our tertiary care institution between September 2007 and October 2018. We characterized patient data, procedure-related factors, complications, and outcomes.

RESULTS

In total, 55 sialendoscopies were performed on 42 patients. Among these, 36 were diagnostic endoscopies and 19 were interventional. Five endoscopies were performed under local anesthesia. We identified 16 sialolithiasis patients, where removal of a sialolith was possible in 11 (69%) cases; one case required a second endoscopy. We removed two sialoliths under local anesthesia. Among recurrent juvenile parotitis (RJP) patients, 18/20 (90%) were symptom-free after a single sialendoscopy, and all after a second endoscopy. The median follow-up time was 70 months. We achieved a 95% success rate in sialendoscopies, with a failure-to-treat rate of 15%. The complication rate for the study cohort was 2%, with prolonged parotid swelling the only complication encountered.

CONCLUSIONS

Sialendoscopy represented a safe and effective method to treat pediatric patients. Local anesthesia was successful in selected cases, even for sialolith removal. Sialendoscopy had a soothing effect on RJP and the majority of sialoliths were suitable for endoscopic removal.
