ABSTRACT
OBJECTIVES: Congenital pyriform sinus fistula (CPSF) is a rare disease that can be easily misdiagnosed. This study investigates the value of ultrasonography in the early diagnosis and treatment of CPSF in children. METHODS: Clinical features and ultrasonography images of 31 CPSF pediatric patients confirmed by operation were retrospectively analyzed, different sonographic features during the infection period and the quiescence period were summarized and the consistency test of ultrasonic recognition and diagnosis between observers was conducted. RESULTS: In this study, 25 CPSF children had thick-walled cystic masses during the infection period, and cystic masses of 8 cases showed gas echo inside; after the modified valsalva maneuver, gas echo was found in another 5 cases. The detection rate of gas can be enhanced through the modified valsalva maneuver and infants' cry so as to provide an important basis for the diagnosis of pyriform sinus fistula. During the quiescent period of inflammation of 6 cases, fistula can be completely shown, and the wall structure has not been completely destroyed, so that the running position of fistula can be clearly seen. Ultrasonography boasted a good inter-observer consistency in identification and determination (Kappa:0.799-0.857; P<0.001). CONCLUSION: Ultrasonography could clearly reveal the position and direction of CPSF fistula. Different ultrasonic characteristics in different periods could provide relevant information for the selection of clinical operation timing and evaluate the post-operative effects.

BACKGROUND: Pyriform sinus fistulas (PSFs) are rare congenital anomalies of the third or fourth brachial pouch. Dyspnea is reportedly secondary to compression by a neck mass. However, hoarseness, as the first symptom of PSF, has not yet been reported. CASE PRESENTATION: This report describes an 11-year-old girl presenting with hoarseness as the first symptom of PSF. Hoarseness occurred 2 days prior to admission. On admission, she had fever, hoarseness, and an elastic soft mass on her left anterior neck. Contrast-enhanced computed tomography of the cervical region demonstrated an abscess partially infiltrating the thyroid gland and an air pocket near the pyriform sinus. Pharyngoscopy revealed swelling of the left arytenoid region, with purulent retention. The left vocal cord was swollen but not paralyzed. Additionally, the laboratory data indicated thyrotoxicosis. Suspecting a PSF infection, parenteral treatment with cefotaxime and dexamethasone was initiated. On the following day, the hoarseness disappeared, and the fever resolved. Four weeks after onset, the thyroid hormone levels returned to the normal range, and a barium esophagogram revealed residual contrast in the left pyriform sinus, leading to a diagnosis of PSF. CONCLUSION: PSF presenting with hoarseness as the first symptom in patients should be considered.

PURPOSE: Pyriform sinus fistula (PSF) diagnosis is often easily delayed and incorrect. Diagnostic values of modalities vary in different situations. The aim of this study was to recommend optimal schemes for diagnosing PSF at different ages and infection stages. METHODS: A search of PubMed, Embase, Cochrane Library, and CBM databases was conducted to identify articles written in Chinese and English concerning PSF diagnosis using keywords: "pyriform sinus fistula", "diagnosis", and relevant synonymous terms. Quality assessment was performed using the Joanna Briggs Institute (JBI) levels of evidence and critical appraisal checklist tool. RESULTS: 111 studies describing 3692 patients were included. The highest true positive rate (TPR) of ultrasonography was 66.67 % in adult cases. Computed tomography (CT) yielded a good TPR (approximately 73 %) in both neonatal and adult patients, and contrast-enhanced CT (84.21 %) was better in adult patients. Most children cases could be accurately diagnosed by barium swallow (BS) examination which was significantly different in acute and non-infection stages (AIS, NIS). Magnetic resonance imaging (MRI) produced a nice TPR in fetal cases (69.23 %) and neonatal cases (54.44 %). Laryngoscopy was also affected by infection stages. TPR of gastroscopy (GS) was the highest in children (86.36 %) and adult cases (87.50 %). CONCLUSION: For fetal cases suspected of PSF, an MRI is recommended. MRI or CT is preferred for neonatal cases regardless of infection stages. Children and adult patients are advised to undergo GS during NIS or AIS, while BS is suggested for NIS. Contrast-enhanced CT can also diagnose adults with PSF in AIS.

Preservation of laryngeal functions after supraglottic laryngectomy depends on both the extent of surgical resection and the type of reconstruction. Any reconstructive modality faces the challenges of preserving voice and swallow function due to the complex and dynamic anatomy of the larynx. In this report, we present a case in which the entire affected unilateral supraglottis and piriform sinus were functionally reconstructed using a triple chimeric superficial circumflex iliac artery perforator (SCIP) free flap. An extended unilateral supraglottic laryngectomy and neck dissection were performed in a 78-year-old male patient presenting with a supraglottic cT4a cN0 cM0 laryngeal cancer. The resulting defect was reconstructed using a triple chimeric SCIP flap from the right inguinal region intended to reconstruct the different affected compartments. It was based on three perforators and consisted of a 4 cm × 3 cm fascial flap from the external oblique muscle and two fasciocutaneous paddles measuring 6 cm × 2 cm and 3 cm × 4 cm. The arterial and venous vessels were anastomosed to the superior thyroid artery and internal jugular vein. The fascial flap was used to reconstruct the aryepiglottic fold. The smaller fasciocutaneous paddle was utilized to reconstruct the affected piriform sinus and former thyroid cartilage compartment, while the larger fasciocutaneous paddle served as a monitor skin flap. The postoperative recovery was uneventful. Laryngeal functions including voice and deglutition were well-preserved after 4 months of rehabilitation. The patient showed no signs of chronic aspiration or tumor recurrence 6 and 12 months postoperatively. The pliable and versatile triple chimeric SCIP flap provides a useful free flap option for a tailored functional reconstruction after an extended supraglottic laryngectomy. Restoration of larynx elevation and mobility with the presented technique substantially improves swallow rehabilitation while preserving the voice.

BACKGROUND: Third and fourth branchial anomalies are rare, accounting for less than 10% of all branchial anomalies. The piriform fossa sinus tract (PFST) typically presents with left-side suppurative thyroiditis, although it can present earlier in neonates as a non-inflamed cystic neck mass. PFST poses a considerable diagnostic challenge with variable clinical and imaging features, leading to long delays to definitive diagnosis and appropriate management. OBJECTIVE: To analyse the patterns of presentation and imaging findings in children with PFST, with a particular focus on neonatal presentation. MATERIALS AND METHODS: This was a retrospective review of the clinical presentation, imaging findings and management in 16 cases of PFST presenting to our tertiary children's hospital between 2003 and 2018. Cases were identified by medical records and picture archiving and communication system (PACS) search using relevant International Classification of Diseases (ICD)-10 coding. RESULTS: Age at presentation ranged from prenatal to 16 years, with a male-to-female ratio of 2:1. All patients presented with neck swelling. Thirteen patients (81%) had suppurative thyroiditis at initial presentation. Two patients had severe thyroiditis/mediastinitis that required intensive care unit admission. Three neonates presented with noninfected, asymptomatic large cystic neck masses; two of these were detected prenatally and misdiagnosed as lymphatic malformations with subsequent spontaneous clinical resolution that later represented with evidence of PFST. The PFST was on the left side in 15/16 (94%) patients. All patients had neck imaging before definitive diagnosis. Imaging studies included radiographs, ultrasound, computed tomography, magnetic resonance imaging and barium esophagram studies. No single modality was diagnostic of PFST in all patients. Seventy-five percent of patients had multimodal imaging before diagnosis. All PFSTs were confirmed by endoscopic visualisation. Management of PFST was by endoscopic cauterisation in 13 patients and open surgery in 2. One patient did not require surgical correction. CONCLUSION: Our study highlights the complex nature of PFST. The anomaly is uncommon, has variable clinical and imaging features and may have a lengthy, complicated course if not considered at initial presentation. An episode of suppurative thyroiditis in a child should prompt investigation for PFST. We describe atypical presentations with cystic masses in neonates that appear to resolve but represent later as typical clinical features of PFST.

BACKGROUND: Pyriform sinus carcinoma with vocal cord fixation is stratified as stage T3 and above, and non-surgical treatment is generally preferred according to the guidelines, aiming to preserve laryngeal function. However, long-term survival is often compromised by deep infiltration of the tumor. Vertical hemipharyngolaryngectomy (VHPL) was previously reported to be a feasible surgical approach for organ preservation. The aim of this study was to evaluate the functional and oncological outcomes of VHPL in patients. METHODS: Patients who underwent VHPL type II (total VHPL, which includes the removal of a vertical section of the thyroid cartilage through the anterior commissure to the upper border of the cricoid cartilage) for pyriform sinus cancer with vocal cord fixation at the authors' institute between 1999 and 2015 were retrospectively analyzed. Functional outcomes concerning swallowing and decannulation were evaluated. Successful functional preservation was defined as laryngeal preservation as well as oral realimentation and decannulation within 6 months after surgery. The oncological outcomes were measured by overall survival (OS) and disease-free survival (DFS) with Kaplan-Meier curves and comparisons were performed between the VHPL-treated patients and patients who underwent non-surgical treatment within the same period. RESULTS: A total of 23 patients (stage T3, 17 patients; stage T4, 6 patients) whose initial treatment was VHPL type II were studied, and a cohort of 123 patients was selected as the control group. Pedicle and free flap reconstructions were performed on 12 and 11 patients, respectively. Postoperative radiation and chemoradiation was performed on 14 and 3 patients, respectively. Flap failure and pharyngeal fistula were detected in 2 and 5 patients, respectively. Oral realimentation and decannulation within 6 months were achieved in 82.6% (19 patients) and 87.0% (20 patients) of patients, respectively, and the total functional preservation rate of the study cohort at 6 months was similar to that of the control cohort. (78.3% vs. 82.9%, p = 0.28). After a median follow-up period of 49 months, 9 recurrences and 8 deaths had occurred in the study cohort. According to the Kaplan-Meier analysis, the study cohort had superior DFS (5-year DFS 60.3% vs. 44.6%, p = 0.04) and similar OS (5-year OS 63.8% vs 57.0% p = 0.28) compared with those in the control group. CONCLUSION: VHPL yielded favorable oncological and functional outcomes in patients with unilateral pyriform sinus carcinoma and vocal cord fixation.

BACKGROUND: A variety of imaging modalities have been described for the diagnosis of congenital pyriform sinus fistula (CPSF). To date, there have been few MRI reports. PURPOSE: To evaluate MRI findings of CPSF and interobserver reliability. STUDY TYPE: Retrospective. POPULATION: In all, 115 patients aged 23 days to 15.4 years at operation. FIELD STRENGTH/SEQUENCE: 3.0T/axial T1 -weighted image (T1 WI)-SPIR, axial T2 WI, axial T2 WI-STIR, coronal T2 WI-SPIR, diffusion-weighted imaging (DWI), axial and coronal gadolinium-enhanced T1 WI-SPIR. ASSESSMENT: For each patient, the medical records, including demographics, clinical manifestations, and MRI findings were reviewed. All the MRI studies were interpreted by three radiologists independently. STATISTICAL TEST: Kendall's W test was made to determine the interobserver reliability of three reviewers for MRI findings. RESULTS: CPSF occurred on the left side in 104 (90.4%) patients and on the right side in 11 (9.6%) patients. The male-to-female ratio was 59:56. The age at first episode varied from birth to 12.3 years. There was one neonate patient, who presented with a unilocular cystic mass in the left neck. A tunnel-like lesion between the pyriform fossa and the upper pole of the thyroid gland, T2 high signal behind the cricothyroid joint, thyroid gland involvement, deep neck abscesses or masses were noted in 46 (40%), 93 (80.9%), 96 (83.5%), and 36 (31.3%) patients, respectively. There was excellent interobserver reliability for all the MRI findings, ranging from 0.84 to 1.00. DATA CONCLUSION: The sinus tract presenting with a tunnel-like lesion goes behind the cricothyroid joint in most cases. For patients presenting with acute suppurative thyroiditis (AST) or neck infection with thyroid gland involvement, the presence of T2 high signal behind the cricothyroid joint highly suggests the diagnosis of CPSF. MRI is a reliable method for the diagnosis of CPSF. LEVEL OF EVIDENCE: 4 TECHNICAL EFFICACY STAGE: 2.

PURPOSE: In neonates, pyriform sinus fistulas and lymphangiomas require different early treatment, such as surgical resection or sclerosing therapy, respectively. We aimed to evaluate the use of sonographic findings for differentiating between pyriform sinus fistulas and lymphangiomas in neonates with a lateral cervical cystic mass. METHODS: Sixteen cases diagnosed with pyriform sinus fistulas (n = 7) or lymphangiomas (n = 9) were included. Sonographic findings, including fistulas from the pyriform sinus, air-containing cysts, abnormal thyroid parenchyma echogenicity, internal septae within the cyst and spread to the opposite cervical site, were compared between neonates with pyriform sinus fistulas and those with lymphangiomas. Fisher's exact was used for statistical comparisons. RESULTS: A significant difference was observed between cases with and without air-containing cysts (present/absent in neonate with pyriform sinus fistula vs lymphangioma: 5/2 vs. 0/9; p = 0.005), abnormal thyroid parenchyma echogenicity (present/absent: 4/3 vs. 0/9; p = 0.019), and internal septae within the cysts (present/absent: 2/7 vs. 9/9; p = 0.005). No significant differences were observed between cases with or without a fistula from the pyriform sinus (present/absent: 2/5 vs. 9/0; p = 0.175) and spread to the opposite cervical site (present/absent: 4/3 vs. 4/5; p = 0.500). CONCLUSIONS: Ultrasound can differentiate pyriform sinus fistulas from lymphangiomas in neonates. In our small cohort, if they exhibited the respective sonographic findings; fistula from pyriform sinus, air-containing cysts or abnormal thyroid parenchyma echogenicity, patients were diagnosed as cases of pyriform sinus fistula. These diagnoses are critical for pediatric surgeons or otolaryngologists in surgical planning.

OBJECTIVE: The aim of this study was to determine if microbiological cultures can guide management of suppurative thyroiditis. DESIGN: This study is a retrospective case series set in 2 tertiary care academic hospitals. METHODS: The microbiological cultures from patients with suppurative thyroiditis who underwent incision and drainage from July 2004 to June 2018 were reviewed. Those who had confirmed pyriform sinus tracts and underwent surgical intervention were included in the study. RESULTS: Fifteen patients satisfied the criteria for inclusion. All had confirmed pyriform sinus tracts and underwent successful intervention. Endoscopic cautery was the most common intervention followed by complete open excision. Five cultures grew alpha Streptococcus, 6 had Eikenella, and 4 Prevotella. Combinations of Eikenella + Prevotella were seen in 3, and 1 sample had all 3 bacteria. Two cultured methicillin-susceptible Staphylococcus aureus alone. One culture was sterile. CONCLUSIONS: The presence of oral flora in an intrathyroidal abscess is confirmatory evidence of a pyriform sinus tract. Further investigations are not needed, and early definitive intervention can be planned.

OBJECTIVES: To evaluate feasibility and efficacy of surgical approach of laryngofissure combined with epiglottis valley in treating locally-advanced pyriform sinus carcinoma. METHODS: Clinical data of 216 patients with T3 and T4a pyriform sinus carcinoma, who came from the Department of Otorhinolaryngology Head and Neck Surgery, Xiangya Hospital, Central South University between January 2013 and December 2019, were retrospectively analyzed. Three different types of surgery were used in these patients. Seventy-three patients were performed by approach of laryngofissure combined with epiglottis valley for partial laryngopharyngectomy (Group I); 75 patients were performed by approach of lateral pharynx for piriform fossa resection (Group II); 68 patients were performed by total laryngopharyngectomy (Group III). All patients were treated with radiotherapy and followed up regularly after operation. Kaplan-Meier regression model was used to analyze the overall survival rate. EAT-10 swallowing scale was utilized to evaluate the postoperative swallowing function, while the rate of tracheal tube extubation and the incidence of postoperative complications in each group were compared. RESULTS: There were 76.7% patients with T3 stage in Group I, 100% patients with T3 stage in Group II, and 64.7% patients with T4a stage in Group III. There was significant difference between them (P<0.01). Clinical stage IV patients in the Group I, Group II, and Group III were 74.0%, 54.7%, and 89.7%, respectively, with significant difference (P<0.01). The 3-year overall survival (OS) rate in Group I, Group II, and Group III were 69.9%, 53.3%, and 58.8%, respectively. Patients in the Group I had a better survival outcome than that in the Group II (P<0.05). The median score of EAT-10 swallowing scale was 12.0 in the Group I, 8.0 in Group II, and 5.0 in Group III, with significant difference (P<0.01). There was no significant difference in the rate of tracheal tube extubation and the incidence of complication among the 3 groups (both P>0.05). CONCLUSIONS: Surgical approach of laryngofissure combined with epiglottis valley in the treating locally-advanced piriform sinus carcinoma presents favorable outcome in terms of survival rate and laryngeal function preservation, which deserves to be promoted.

INTRODUCTION: Hypopharyngeal squamous cell carcinoma (SCC) is rare, but highly aggressive. Due to the advanced stage of this cancer at the time of diagnosis, radical surgery with reconstruction of pharynx is the standard care with high morbidity and mortality rate. A safer partial pharyngectomy could also be used for invasive hypopharyngeal cancer. In this study, we investigated the short and long-term outcomes in patients with SCC of the pyriform sinus apex undergoing standard partial pharyngectomy using a new suturing technique, called end to side technique. METHODS: This case series was performed on 8 patients with SCC of the pyriform sinus apex at the otorhinolaryngology clinic. All participants underwent standard partial pharyngectomy using "end to side technique". Post-operative evaluations included 6 and 12 months CT scan and 1-year barium swallow. RESULTS: Of 8 patients, 7 were male (87.5%) and 1 was female (12.5%) with a mean age of 60 years old. All patients were diagnosed at stage III of hypopharyngeal cancer and cervical lymph node involvement was reported in 3 patients (37.5%). Tumor margins were negative in all patients. Fistula was reported in 2 patients (25%) which was managed using conservative treatments. CONCLUSIONS: According to our study, the standard partial pharyngectomy with end to side technique is a safe and feasible method for the surgical resection of the squamous cell carcinoma of the pyriform sinus apex with good short-term and long-term outcomes.

PURPOSE: Congenital pyriform sinus fistula (CPSF) often presents diagnosis and treatment challenges. This study aimed to explore the treatment principles and to evaluate the effectiveness of the hypothermia plasma cauterization with suspension laryngoscopy for CPSF. METHODS: The medical records of 56 patients with CPSF from January 2000 to December 2019 were retrospectively reviewed. RESULTS: Of the 56 cases, the lesions were predominantly located on the left side (95%), and the accuracy of the first diagnosis was 30%. Ultrasound showed an abnormal rate of 86%, while CT or MRI displayed an abnormal anatomic lesion of 92%. The 3D visual reconstruction enabled the analysis of morphological characteristics of CPSF. The positive predictive value of barium esophagography was 89%, whereas the positive rate of the internal opening in CPSF under local anesthesia laryngoscopy was 33%. Nine cases of sinus type underwent open resection, and the recurrence rate was 33%. Interestingly, ten patients with sinus type underwent hypothermia plasma cauterization with suspension laryngoscopy, leading to a success rate of 100% without apparent complications. CONCLUSIONS: Hypothermia plasma cauterization with suspension laryngoscopy alongside 3D imaging is both minimally invasive and repeatable with neglectable complications, which has the potential to serve as the first-line treatment for CPSF in the future.

Objectives: To evaluate changes in incidence and survival of patients diagnosed with hypopharyngeal cancer (HPC) in Denmark in the period 1980-2014.Methods: All patients registered with HPC in the Danish Cancer Registry (DCR) in the period 1980-2014 were included. Age-adjusted incidence rates (AAIRs), average annual percentage change in incidence, and overall survival were calculated.Results: Two thousand and nine patients were included (79.7% men). The overall AAIR increased significantly from 0.3 per 100,000 to 1.1 per 100,000 during the study period, corresponding to an increase of 4.1% per year. The most frequent histology was squamous cell carcinoma (SCC) comprising 90.3%. The overall five-year survival increased with 13.5 percentage points from 13.4% in the period 1980-1985 to 26.9% in the period 2010-2014. Women demonstrated better survival compared to men with a hazard ratio of 0.83, and patients with SCC had better survival compared to the remaining histology groups.Conclusions: This nation-wide study, covering nearly four decades, showed a significant increase in incidence and survival of HPC in Denmark.

OBJECTIVES: To clarify the reliability of fiberoptic endoscopic evaluation of swallowing (FEES) compared to videofluoroscopic swallowing studies (VFSSs). Second, we explored the effect of the chin-down maneuver in the presence or absence of vocal fold paralysis (VFP) using FEES in patients with 3-field lymphadenectomy (3FL) postesophagectomy. DESIGN: Retrospective data collection from FEES and VFSS. SETTING: Dysphagic clinics in the ear, nose, and throat department. PARTICIPANTS: Patients (N=15) underwent esophagectomy with 3FL at the Department of Gastroenterologic Surgery, during a period of 12 months. INTERVENTIONS: The patients underwent FEES and VFSS with neutral and chin-down maneuvers 2 weeks postoperatively. Two raters of speech pathology blindly scored aspiration, penetration, delayed initiation, and pharyngeal clearance in the pyriform sinus and vallecula, respectively, from recorded movie clips of both examinations, using the penetration aspiration scale (PAS) and modified Hyodo FEES rating scale. MAIN OUTCOME MEASURES: The intrarater and interrater correlation coefficients of each parameter examined with FEES. Statistical comparison of each parameter between FEES and VFSS and of each parameter evaluated using FEES between 2 maneuvers with or without VFP. RESULTS: The intrarater and interrater correlation coefficients of the PAS and pyriform sinus examined with FEES were both statistically consistent between the 2 raters. The PAS and pyriform sinus evaluated using FEES were significantly correlated with those evaluated in a VFSS (P<.05). The 2 parameters evaluated using FEES were significantly (P<.05) improved with the chin-down maneuver compared to the neutral maneuver, especially in VFP patients. CONCLUSION: FEES performed postesophagectomy with 3FL for evaluation of aspiration is as reliable statistically as VFSSs. The chin-down maneuver is especially useful for reducing the PAS score and pyriform sinus in VFP patients.

Thyroglossal duct cysts (TDC) are the most common congenital neck masses. Although they are anatomically closely related to the larynx, intra-laryngeal extension is very rare. We present a case, review the literature and discuss the challenges of intra-laryngeal TDC. A 55-year-old man presented with a neck mass associated with dysphagia. Computer Tomography neck scan showed a midline cyst extending to the pre-epiglottic space with partial obliteration of the right pyriform sinus and narrowing of the larynx. The cyst was excised en-bloc via Sistrunk procedure. Intra-laryngeal TDC are surgically challenging due to risk of perforation into the aerodigestive tract.

Objective: To analyze the long-term outcome of patients with pyriform sinus squamous cell carcinoma treated with planned preoperative (chemo-) radiotherapy plus laryngeal function sparing surgery. Methods: Patients with stage â ¢/â £ pyriform sinus squamous cell carcinoma treated with planned preoperative (chemo-) radiotherapy plus laryngeal function sparing surgery during 1999 to 2000 were retrospectively analyzed. Data including concurrent chemotherapy or not, postoperative pathological diagnosis, postoperative complications, recurrence and survival were collected. Twenty patients were treated with preoperative radiotherapy while 14 patients with preoperative chemo-radiotherapy. Results: Among 31 cases of postoperative pathological diagnosed as pyriform sinus, 12 (38.7%) cases without tumor residue, 7 (22.5%) cases with severe radiation response and 12 (38.7%) cases with tumor residue. The 5-year cumulative local recurrence rate, regional recurrence rate and distant metastasis rate was 14.5%, 13.7% and 23.5%, respectively. Five-year cumulative overall survival rate and recurrence-free survival rate were 69.6% and 65.4%, respectively. Nine deaths were attributed to distant metastasis (8 cases) and regional recurrence (1 case). Conclusion: Most patients with pyriform sinus squamous cell carcinoma acquire long-term survival after treated with planned preoperative (chemo-) radiotherapy plus laryngeal function sparing surgery, and distant metastasis is the main cause of death.

OBJECTIVE: Observation of a sinus tract during a barium swallow examination is important for the diagnosis of pyriform sinus fistula; however, to our knowledge, no reports have existed regarding the optimal timing of the examination in relation to the onset of symptoms. The purpose of this study was to compare the timing of the examination, patient age, the number of inflammatory episodes that occurred before the examination, and the barium concentration used for examinations with true-positive results versus those with false-negative results for the diagnosis of pyriform sinus fistula. MATERIALS AND METHODS: Twenty-three children with pyriform sinus fistula were included. The timing of the examination, patient age, the number of the inflammatory episodes that occurred before examination, and the barium concentration used were compared between examinations with true-positive results and examinations with false-negative results, by use of the Mann-Whitney U test. RESULTS: The examination had true-positive results for 60.9% (14/23) of patients and false-negative results for 39.1% (9/23) of patients. The mean (± SD) interval since the onset of symptoms was significantly shorter for patients with false-negative examination results than for those with true-positive examination results (26.33 ± 21.17 days vs 48.57 ± 17.67 days; p = 0.020). By 6 weeks after the onset of symptoms, more than half of the examinations had false-negative results. No significant difference in patient age (p = 0.238) or number of previous inflammatory episodes (p = 0.431) existed between examinations with true-positive and false-negative results; however, a significant difference was noted in the mean barium concentration used (88.57% ± 31.53% vs 52.86% ± 18.68% weight/volume, respectively; p = 0.014). CONCLUSION: Barium swallow examinations with false-negative results were significantly more likely when the examination was performed soon after the onset of symptoms. Therefore, early first examinations would not be recommended for the diagnosis of pyriform sinus fistula, especially in terms of radiation exposure. A higher barium concentration may be useful.

OBJECTIVES: Ultrasonography (US) has been considered to have a more limited role in the diagnosis of pyriform sinus fistulas than computed tomography. The aim of this study was to evaluate the US characteristics of pyriform sinus fistulas involving the thyroid gland in an attempt to improve our ability to diagnose this condition using US. METHODS: Between 2005 and 2016, 14 patients with pyriform sinus fistulas presenting as suppurative thyroiditis or as thyroid nodules were enrolled in the study. Their US images were reviewed to identify US characteristics indicating the presence of an underlying pyriform sinus fistula and compared with the computed tomographic images. RESULTS: A hypoechoic tubular lesion across the thyroid gland was identified in 9 patients (64.3%). Hyperechoic foci or echogenic lines were found within the lesion in 10 patients (71.4%). A hypoechoic rim was found at the boundary of the lesion in 7 patients (50.0%). A lesion emerging from the posterolateral aspect of the thyroid cartilage was found in 4 patients (28.6%). Thirteen (92.9%) of the 14 patients had 1 of these 4 findings. CONCLUSIONS: Ultrasonography would be a useful diagnostic modality for indicating the presence of an underlying pyriform sinus fistula in patients with suppurative thyroiditis or a thyroid nodule and can be used as a first-line diagnostic tool to screen for pyriform sinus fistulas.
