What is the impact of previous cholelithiasis on sialolithiasis: A systematic review and meta-analysis.

Introduction: A sialolith is a salivary stone usually presenting with swelling and pain in the affected salivary gland, most commonly the submandibular gland. There have been speculations about the association between this condition and other systemic diseases, especially those forming stones, such as nephrolithiasis and cholelithiasis. This systematic review and meta-analysis aimed to summarize the studies assessing the relationship between cholelithiasis and sialolithiasis. Methods: PubMed/MEDLINE, Scopus, Web of Science, and Embase electronic databases were searched according to the keywords related to both disorders without any publication date or language restriction. Case-control and cohort studies evaluating the relationship between salivary and biliary stones were considered eligible. Quality assessment was performed following Newcastle-Ottawa Scale (NOS) for quality assessment of case-control studies. All meta and statistical analyses were performed with Comprehensive Meta-Analysis software. Results: Two studies fully complied with the defined eligibility criteria and were included, both of which were case-control studies using national-scale databases. In both surveys, the prevalence of previous gallstones in patients with sialolithiasis was compared to that of a control group. Though one of the studies found that there is no relationship between sialolithiasis and cholelithiasis, the meta-analysis revealed that previous cholelithiasis is significantly more prevalent among patients with sialolithiasis (P = 0.000), with an odds ratio of 2.04. Conclusion: It seems that cholelithiasis is significantly associated with an increase in salivary stone formation. Therefore, a thorough salivary examination in all patients declaring current or past cholelithiasis is recommended. However, more studies, especially prospective cohorts, are needed to make firmer conclusions.

[Lithiasic salivary gland pathologies]. / Pathologies lithiasiques des glandes salivaires.

LITHIASIC SALIVARY GLAND PATHOLOGIES. Sialolithiasis is the most frequent pathology affecting the salivary glands. Almost 80% of these lithiasis affect the submandibular gland, in the Wharton duct whilst 20% occur in the parotid gland in the Stenon duct. The diagnosis is based on typical patient interrogation and clinical symptoms (intermittent facial swelling associated with eating, sialadenitis) and/or on paraclinical examination. Ultrasound echography is often prescribed, but CT-scan and sialo-MRI offer a more precise preoperative assessment. Minimally-invasive gland-preserving techniques such as sialendoscopy (combined or not with transoral duct surgery) are nowadays considered to be the method of first choice. These methods reach success rates above 80% and significantly reduce surgical complications and hospital stay.

PATHOLOGIES LITHIASIQUES DES GLANDES SALIVAIRES. Parmi les pathologies des glandes salivaires, les lithiases des canaux salivaires sont les plus fréquentes. Elles sont le plus souvent retrouvées dans les glandes sous-maxillaires au niveau des canaux de Wharton (80 %), et plus rarement dans les glandes parotides au niveau des canaux de Sténon (20 %). Le diagnostic repose sur l'interrogatoire et la clinique, qui peuvent être évocateurs (hernie ou coliques salivaires, sialite aiguë), et sur l'imagerie. L'échographie est un examen diagnostique très accessible, mais le scanner et la sialo-IRM permettent une évaluation préopératoire plus précise. Le traitement repose en première intention sur des traitements chirurgicaux conservateurs et mini-invasifs tels que la sialendoscopie, associée ou non à une approche transorale, qui sont efficaces dans 80 % des cas et permettent de réduire les complications postopératoires et la durée d'hospitalisation.

Transoral submandibulotomy plus duct marsupialization; an appropriate approach for the treatment of proximal submandibular sialolithiasis; a long-term follow-up study.

BACKGROUND: Sialolithiasis is the most common salivary gland-related disease worldwide, leading to sialadenitis. Although there is no serious problem with surgical removal of stones at the middle and distal parts of the Wharton's duct, the approach for treating proximal stones located near to hilum and its adjacent parenchyma is a challenge. The current study has aimed to evaluate the outcome of transoral submandibulotomy for submandibular gland stone treatment. METHODS: This study was conducted on 63 patients with proximal (or deep hilar) submandibular sialolithiasis treated with transoral submandibulotomy and duct marsupialization from January 2011 to April 2019 in Pars hospital. Complications of the old fashion surgery (transcervical submandibulectomy) were assessed in this method (number and size of the stone(s), relapse of sialolithiasis-related obstructive symptoms, partial or complete removal of the stone(s), sialolithiasis recurrence, postoperative surgical or nonsurgical intervention, foreign body sensation, and taste sensation quality). RESULTS: The stone(s) was located at the proximal of the duct in 68% of the cases, while 32% of the stones were located at the deep hilar region. The mean size of the stones was 1.28±0.51 cm. Postoperative inflammation, postoperative pain, sialolithiasis recurrence, obstructive symptoms, postoperative nonsurgical intervention, postoperative surgical intervention, reduced taste sensation, and foreign body sensation were presented in 24%, 29%, 29%, 44%, 14%, 6%, 11%, and 10% respectively. Eighty-nine percent of recurrences were healed spontaneously. CONCLUSION: Considering the cosmetic advantage due to the lack of cervical surgery scar (which is mandatory in old fashion transcervical method), long-term follow-up of transoral submandibulotomy showed successful outcomes regarding neurological impairment, postoperative pain and inflammation and incredibly complete stone removal that was found in all of the patients. In addition, submandibular duct marsupialization is recommended based on our study.

[Endoscopy-assisted transoral removal of deep hilar and intraparenchymal stones in the Wharton's duct].

Objective: To investigate the different surgical approaches and long-term outcomes of endoscopy-assisted transoral removal of deep hilar and intraparenchymal stones in the Wharton's duct. Methods: From January 2008 to March 2018, 481 consecutive patients with deep hilar and intraparenchymal calculi in the Wharton's duct underwent endoscopy-assisted transoral removal at Deparment of Oral and Maxillofacial Radiology, Peking University School and Hospital of Stomatology. There were 250 males and 231 females. Their ages ranged from 9-86 years. We operated 476 patients under local anesthesia on an outpatient basis, and the remaining 5 were operated under general anesthesia. On the basis of ultrasonography, spiral CT, sialography and endoscopy, the calculi were classified into 4 types: hilum stones (located at the hilum or proximally with a distance <5 mm from the hilum), infra-hilum stones (intra-glandular stones with a distance of 5-10 mm from the hilum), intraparenchymal stones (with a distance ≥10 mm from the hilum), and multiple stones (concomitant hilum and intra-glandular stones). The treatment approaches included: hilum duct slitting, intraparenchymal duct slitting, submandibulotomy and intraductal retrieval. The success rate, immediate safety and effectiveness of different types of stones were evaluated. After surgery, the patients were followed up, and gland function was analyzed on the basis of clinical symptoms and signs. Results: The calculi sizes varied from 3 to 25 mm, with a mean of 7.8 mm. The calculi were located in the right submandibular gland in 259 patients, in the left submandibular gland in 219 patients and in bilateral glands in 3 patients. The calculi were successfully removed in 446 glands, with a success rate of 92.1% (446/484). The success rate varied according to the stone sites: 97.8% (363/371) for hilum stones, 64.4% (29/45) for infra-hilum stones, 4/16 for intraparenchymal stones and 96.2% (50/52) for multiple stones. The main treatment methods applied included hilum duct slitting in 347 glands, intraparenchymal duct slitting in 13, submandibulotomy in 4, intraductal retrieval in 73, and hilum duct slitting accompanied by intraductal retrieval in 9. Ductal breakage occurred in 2 glands. All patients complained of mild to moderate pain with a duration of 3-7 days. Nine had temporal lingual nerve injury. During 3-120 months' follow-up (mean 36 months) of the total 484 glands, 1.6% (7/446) developed ranula, 1.3% (6/446) experienced obturation of the main duct and 2.0% (9/446) had recurrent stones. The remaining 95.1% (424/446) glands were symptom-free with good function. Conclusions: Endoscopy-assisted transoral removal of deep hilar and intraparenchymal submandibular calculi is a safe and effective gland-preserving procedure. According to the depth, size and number of the calculi, variant surgical approaches should be attempted to maximize the success rate and to minimize the side effects.

Submandibular sialolithiasis with CT and scintigraphy: CT values and salivary gland excretion in the submandibular glands.

PURPOSE: Sialolithiasis is one of the most prevalent large obstructive disorders of the submandibular glands. The aim of this study was to investigate submandibular sialolithiasis with computed tomography (CT) and scintigraphy, with a particular focus on the relationship between CT values of the submandibular glands and their excretion rate. MATERIALS AND METHODS: Fifteen patients with submandibular sialolithiasis who underwent CT and salivary gland scintigraphy were included in this study. The relationship between the CT values of submandibular glands with and without sialoliths and salivary gland excretion measured using salivary gland scintigraphy was statistically analyzed. Dynamic images were recorded on the computer at 1 frame per 20 seconds. The salivary gland excretion fraction was defined as A (before stimulation test [counts/frame]) / B(after stimulation test [counts/frame]) using time-activity curves. RESULTS: The CT values in the submandibular glands with and without sialoliths was 9.9±44.9 Hounsfield units (HU) and 34.2±21.8 HU, respectively (P=.233). Regarding the salivary gland excretion fraction using scintigraphy, the A/B value in the submandibular glands with sialoliths (1.09±0.23) was significantly lower than in the submandibular glands without sialoliths (1.99±0.57, P=.000). CONCLUSION: Assessments of the CT values and the salivary gland excretion fraction using scintigraphy in the submandibular glands seem to be useful tools evaluating submandibular sialolithiasis.

Pediatric sialolithiasis is not related to oral or oropharyngeal infection: A population-based case control study using the Korean National Health Insurance Database.

OBJECTIVES: Poor oral hygiene is one of the risk factors for sialolithiasis particularly in adults; however the etiology of sialolithiasis in pediatric patients remains largely unknown. The purpose of this study is to identify the association between sialolithiasis and the oral/oropharyngeal infections in the pediatric population, as surrogate indicators for oral hygiene and retrograde infections to the affected salivary gland. METHODS: This was a population based case-control study using the Korean National Health Insurance Database. We identified 10,095 pediatric patients, diagnosed with sialolithiasis, as cases (study period 2011-2015) and 50,475 age/gender/residence matched subjects without sialolithiasis, but with unrelated diseases (e.g., simple trauma in extremities) were set as controls. Logistic regression analyses were conducted to evaluate the association of sialolithiasis with oral or oropharyngeal infections. RESULTS: The morbidity rate of sialadenitis was much higher in the cases than the controls (32.92% vs 0.72%, p < 0.0001). By contrast, the prevalence of oral or oropharyngeal infections (stomatitis, gingivitis, periodontitis, and pharyngo-tonsillitis) was significantly lower in pediatric sialolithiasis patients in all age (0-18) groups. The adjusted odds ratios of the multivariate analyses also confirmed significantly less prevalence of the oral and oropharyngeal infections in pediatric sialolithiasis patients. CONCLUSION: Oral or oropharyngeal infections were inversely associated with pediatric sialolithiasis, suggesting that pediatric sialolithiasis may result from the intrinsic factors of the salivary gland itself, not from oral or oropharyngeal infections.

[Paying attention to the protection of the function organ of submandibular gland].

Submandibular gland is an important human function organ. With the wide application of sialoendoscope and new understanding of IgG4 related sialadenitis, a lot of submandibular glands which were previously considered to be removed are preserved. However, some submandibular glands which might be preserved are still unfortunately sacrificed. Therefore, we advocate the popularization and promotion of new knowledge and techniques and should pay more attention to the protection of the function organ of submandibular gland.

Chronic sialadenitis due to the stone inside the accessory duct of submandibular gland.

PURPOSE: Sialolithiasis is the most common cause of chronic sialadenitis. In this case report, intraoperative finding of an accessory submandibular duct, obstructed with stone, originating from the same gland nearby the main Warthon's duct, is presented. CASE REPORT: A 22-year-old male patient, suffering from eating-related pain and swelling in his left submandibular region, was diagnosed with left sublandibular gland sialadenitis with radiologically manifested sialolithiasis, and gland excision was advised. Surgery was performed under general anesthesia. When the full anatomical scenery was delineated before excision of the gland, we surprisingly encountered two submandibular ducts originating from ipsilateral gland, one of them was obstructed with stone. After two ducts were ligated, the gland with sialolith was excised. According to histopathologic examination, the duct obstructed with stone was identified as the accessory duct and the other one was the main Wharton's duct. Postoperative days were uneventful; no neurologic complication was observed. CONCLUSIONS: Otolaryngologists should be aware of anatomic variations of the submandibular duct(s) to avoid possible complications, especially intraoperatively, because rutine preoperative radiologic preparation does not include investigation of possible accessory ducts.

Transoral Stensen's Duct Approach: A 22-case retrospective study.

INTRODUCTION: Parotid gland duct lithiasis is preferentially managed using minimally-invasive techniques such as sialendoscopy and lithotripsy. However, these 2 techniques cannot remedy all obstructions and other techniques such as the Transoral Stensen's Duct Approach (TSDA) may sometimes be helpful. MATERIAL AND METHODS: A retrospective study of patients treated with TSDA was conducted to evaluate this procedure between 2006 and 2013. Criteria for inclusion were: failures for lithiases (22 patients and 28 lithiases) treated with sialendoscopy and/or lithotripsy for parotid gland duct obstruction. Mean follow-up was 47.4 months. Pain intensity, swelling and occurrence of infectious episodes were evaluated immediately and after middle-term and long-term follow-up (up to 36 months). RESULTS: The best results were obtained for anterior lithiasis, with an 87.5% immediate success rate. Morbidity was low with 2 transient facial nerve upper buccal branch palsies and 2 post-operative stenoses. DISCUSSION: TSDA is an easy-to-perform and safe technique that can be recommended in cases of sialendoscopy or lithotripsy failure for anterior-third parotid duct lithiasis. Even if this technique has shown limitations for more posterior lithiases, or other causes of obstruction (stenosis, megaduct), it requires no specific material and may be useful. It may avoid an external combined approach or a parotidectomy.

Rigid swelling of sublingual caruncle area due to the salivary gland duct obstruction by a sialolith

Sialolithiasis is the presence of calculus within the ductal system of a salivary gland. Among the diagnostic methods are inspection, palpation, checking the amount of saliva secreted and the identification of a sialolith. The authors present the case of a 37-year-old female patient with edema of the submandibular area and a bulging sublingual caruncle due to a calculus that obstructed the salivary gland ostium.

Penetração espontânea de objeto metálico em glândula submandibular: relato de caso / Spontaneous penetration of a metalic object in the submandibular gland: case report

Introdução: A obstrução de um ducto salivar por corpo estranho, em que ocorre inflamação crônica e fibrose de glândulas salivares, é de denominada sialoadenite. A obstrução de um ducto salivar por passagem retrógrada acidental de um corpo estranho é muito rara. Revisão de Literatura com Diagnóstico Diferencial: Alguns tipos de corpos estranhos em glândulas salivares já relatados na literatura: cerdas de escova de dente, fios de cabelo, espinha de peixe, semente de girassol, palha e até mesmo lascas de unhas. Esses corpos estranhos se alojam nas glândulas passando pelos ductos salivares gerando o quadro de sialoadenite cujos principais sintomas são: dor, edema e endurecimento da glândula acometida, além de diminuição da secreção salivar. Alguns dos diagnósticos diferenciais que devem ser considerados diante desses sintomas são: síndrome de Sjögren, sialolitíase, sialoadenite aguda e neoplasias de glândulas salivares. Apresentação de Caso Clínico: J.C.S., 32 anos, masculino, procurou atendimento médico com queixa de dor e abaulamento em região submandibular direita há 7 dias, depois de “chupar” um grampo aberto que “desapareceu” no assolho de sua boca. Discussão: O caso foi analisado sob alguns aspectos, para compara-lo com outros casos já relatados na literatura, como: idade, sexo, exames realizados, tratamento adotado, hábitos incomuns como “chupar grampos”. Comentários Finais: Para fazer o diagnóstico de sialadenite por corpo estranho é essencial fazer uma boa anamnese e inspeção da glândula e, assim, conseguir excluir outras hipóteses.

Introduction: The obstruction of a gland duct due to a foreign body, associated with chronic inflammation and fibrosis of the gland, is named sialadenitis. The obstruction of the salivary duct by retrograde passage of an accidental foreign body is pretty rare. Literature Review with Differential Diagnosis: Some types of foreign bodies in the salivary glands already reported in the literature: toothbrush bristles, hairs, fishbone, sunflower seed, straw and even splinters nail. These foreign bodies are lodged in the glands by passing through salivary ducts causing sialoadenitis, whose main symptoms are pain, swelling and hardening of the affected gland, and decreased salivary secretion. Some of the differential diagnosis to be considered due to such symptoms are: Sjögren’s syndrome, sialolithiasis, acute sialadenitis and salivary gland neoplasms. Clinical Case Report: J.C.S, 32 years old, male, complains of pain and swelling of the submandibular region since he “sucked” an opened clip and it “disappeared” in his mouth seven days ago. Discussion: Some aspects of the case were analyzed and compared with others studies of the literature, such as: age, gender, exams that are usually used, chosen treatment, besides unusual habits like “suck clips”. Final Comments: The diagnosis of sialadenitis due to foreign body needs a careful inspection of the gland and also a good anamnesis, to be able to exclude other hypotheses.

Pediatric sialadenitis.

Sialadenitis in the pediatric population accounts for up to 10% of all salivary gland disease. Viral parotitis and juvenile recurrent parotitis are the two most common causes. Multiple factors, independently or in combination, can result in acute, chronic, or recurrent acute salivary gland inflammation. Sialendoscopy has emerged as the leading diagnostic technique and intervention for pediatric sialadenitis. Sialendoscopy is a safe and effective gland-preserving treatment of pediatric sialadenitis. Investigational studies are needed to address the impact of steroid instillation, postoperative stenting, and long-term outcomes of pediatric sialendoscopy. This article presents a comprehensive review of pathophysiology, clinical presentation, diagnosis, and treatment of pediatric sialadenitis.

Parotid sialolithiasis in a two-year-old boy.

Sialolithiasis is caused by the obstruction of a salivary gland or its excretory duct by the formation of calcareous concretions or sialoliths; this results in salivary ectasia and provokes subsequent dilation of the salivary gland. Sialolithiasis is relatively common, accounting for 30% of salivary diseases; however, it is rarely observed in childhood. This case report describes a 2-year-old male patient who complained of a painful swelling over the right cheek, and presented with palpable stones and pus discharge from the orifice of the right Stensen's duct. Computerized tomography of the neck confirmed the diagnosis, and the patient received intravenous empiric antibiotics combined with intraoral sialolithotomy. We also provide a review of the spectrum of concepts regarding the pathogenesis, diagnosis, and treatment of sialolithiasis.

Sialolito gigante em ducto de Warton: relato de caso clínico / Giant sialolith in Warton's duct: a clinical report

Objetivo: Relatar o caso clínico de um sialolito gigante localizado no ducto de warton da glândula submandibular. Relato de caso: Paciente 59 anos, leucoderma com estado de saúde geral regular, compareceu ao serviço de cirurgia Buco-Maxilo do Hospital Santa Isabel/João Pessoa-PB com queixa de "inchaço abaixo da língua e dor quando maior salivação". Ao exame clínico intra-oral foi observado aumento de volume no trajeto do ducto de Warton no segmento de assoalho de boca e após realização de exame de imagem do tipo oclusal de mandíbula observou-se extensa imagem radiopaca em área ductal, concluindo-se assim o diagnóstico de sialolitíase do ducto de Warton. Foi realizado remoção cirúrgica sob anestesia local, com o restabelecimento da patência do ducto e normalidade do fluxo salivar. Conclusão: O diagnóstico e tratamento efetuado no relato de caso clínico descrito foram embasados na literatura e obtiveram eficácia clínica.

Objective: to report a clinical case of a giant sialolith found in the Warton's duct of the submandibular gland. Case Report: Patient 59 years, Caucasian with regular general state of health, attended the Oral and Maxillofacial Surgery service at the Santa Isabel Hospital, Joao Pessoa - PB complaining of "swelling under the tongue and pain when salivating. On intraoral clinical examination, we observed swelling in the path of Warton's duct in the mouth floor segment. After radiographical examination (mandibular occlusal radiograph), we found extensive radiopaque image in the ductal area, establishing therefore a diagnosis of sialolithiasis of Warton's duct. Surgical removal was performed under local anesthesia, with restoration of patency of the ducts and normal salivary flow. Conclusion: The diagnosis and surgical treatment described in this case report were supported by the literature and achieved clinical efficacy.
